⚕️FREE MSRA PODCAST –Posterior Cruciate Ligament (PCL) Tear

🎧 Your high-yield revision audio for mastering PCLtears — for the MSRA, exams, or on the go.

🧠Key Learning Points

📌Definition

• Posterior cruciate ligament (PCL) tear = injuryto the main ligament that stabilises the back of the knee, preventing the tibiafrom moving backwards relative to the femur

• PCL provides up to95% of posterior knee stability

📌Causes & RiskFactors

• Direct blow to the front of the knee (e.g.“dashboard injury” in car crashes)

• Hyperextension injuries

• Falling hard onto a bent knee

• High-impact/contact sports (football, rugby)

• Previous PCLinjury increases re-injury risk

Mnemonic: DHFSA — Dashboard, Hyperextension,Fall (bent knee), Sports, Accidents

📌Pathophysiology

• Force exceedsPCL’s tensile strength → partial or complete tear

• Posterior tibialdisplacement = loss of knee stability

• Hamstrings/gravitypull tibia backwards in absence of PCL

📌Symptoms &Clinical Features

• Knee pain, often with swelling and a sensation of instability(“knee might buckle”)

• Difficulty bearingweight

• Instability especially with walkingdownhill/stairs

• May be lessdramatic than ACL tears (often less “pop”)

📌DifferentialDiagnosis

• ACL tear

• Medial/Lateralcollateral ligament tears (MCL/LCL)

• Meniscal tear

• Patellardislocation

• General kneeinstability

• Osteoarthritis (inchronic cases)

📌Diagnosis

• Physical exam:

 – Posterior drawer test (most sensitive)

 – Posterior sag test (Godfrey’s test)

• MRI: gold standard for assessingligament/tissue injuries and grading severity

• X-ray: rules out fractures (especially tibialplateau avulsion)

📌Management

• Conservative for most isolated, mild/moderatetears:

 – PRICE/PRICER: Pain relief, Rest, Ice,Compression, Elevation, early Rehabilitation

 – Physiotherapy: emphasise quadriceps strengthening (quads = key fordynamic stability)

 – Bracing orcrutches for some injuries

• Surgical:

 – Reserved forsevere/complete tears, multi-ligament injuries, avulsion fractures, orpersistent instability

 – Procedure = PCLreconstruction (using tendon grafts)

Mnemonic: "Quadsfor PCL" — quad strength is vital in rehab!

📌Prognosis &Complications

• Good prognosis with early, focused rehab — manyregain full function

• Untreated/unstableknees risk chronic pain, instability, and earlyosteoarthritis

• Complications: Patellofemoral/medial arthrosis,chronic knee pain

• Commitment torehab is crucial for long-term outcome

🎙️Deep Dive:Prepatellar Bursitis (Housemaid’s Knee)– MSRA Essentials

Knee pain right overthe front of the patella? Swelling like a little water balloon? In thisepisode, we break down Prepatellar Bursitis,a deceptively simple but clinically important condition — especially for MSRA revision. Whether it’s from kneeling,trauma, or infection, we walk you through whatmatters and why.

🧠Key Concepts Covered

• 📍 Definition: Inflammation of the prepatellar bursa,a fluid-filled sac sitting just in front of the kneecap

• 💥 Causes: Repetitive kneeling (👷‍♂️ carpet layers, cleaners), direct trauma,infection, or associated inflammatory conditions (RA, gout)

• ⚠️Septic vs Non-septic: ~30% are infected – often Staph aureus

• 👩‍⚕️ Risk Factors: Manual occupations, contact sports,immunosuppression, skin breaks

• 🔍 Pathophysiology: Inflammation or bacterial colonisation of the bursa→ swelling, fluid accumulation, tenderness

🔄DifferentialDiagnosis

📌Don't assume it’sbursitis — rule out:

• Septic arthritis – red flag: systemic symptoms,joint pain with all movement

• Patellar tendonitis – pain below the patella

• Meniscal tear – twisting injury,locking/clicking

• Patellofemoral pain syndrome – ache behindkneecap, worse on stairs

• Cellulitis, infrapatellarbursitis, gout/pseudogout

🔬Diagnosis – What YouNeed to Know

✅Aspiration is key – gold standard to rule out infection or crystals

 • Send fluid for:

  – WCC, Gram stain& culture

  – Crystal analysis:

   • ⬆️MSU = gout

   • Rhomboid CPP =pseudogout

✅ Imaging:

 • Not routinely needed unless complicationssuspected

 • 🩻 X-ray: rule out trauma

 • 🧲 MRI/ultrasound: only if persistent or uncertain

💊Treatment Pathways

Type

First-line Management

Second-line

Non-septic

PRICE: rest, ice, NSAIDs, knee pads 🧊

Aspiration ± steroid (if no sepsis)

Septic

Empirical IV antibiotics 🚨

Repeated aspiration or surgical drainage

➡️ Consider bursectomy forchronic/recurrent cases

➡️ Patient education on knee protection is crucialfor prevention 🔁

📈Epidemiology &Prognosis

• 🧍‍♂️ More common in men aged 40–60

• 💼 Linked to manual jobs (e.g. cleaners, roofers, gardeners)

• ~1 in 10,000incidence/year in UK

• 🤒 ~30% are septic – more likely in children or immunocompromised

• 🩹 Non-septic cases usually resolve with conservative care

• 🔁 Recurrence possible if aggravating factors not addressed

📝Rapid MSRA Recap

• Swelling directly over kneecap = think prepatellar bursitis

• Always ask:occupation, trauma, systemic signs

• Aspiration rules in/out: sepsis, gout,inflammation

• Treatment:conservative for non-septic, antibiotics &drainage for septic

• Preventrecurrence: avoid kneeling, use knee pads

⚕️ FREE MSRA PODCAST – Pubic Symphysis Dysfunction (SPD)
🎧 A clear, high-yield breakdown of this often underdiagnosed source of pelvic pain in pregnancy. Perfect for exam prep and real-life clinical scenarios.

🧠 Key Learning Points

📌 Definition
• Pubic Symphysis Dysfunction (SPD) = pain and instability at the joint uniting the left and right pelvic bones
• Common in pregnancy due to hormonal laxity and altered biomechanics
• Can also be caused by trauma, overuse, or pelvic inflammation
💡 Mnemonic: “Hormones, Hits, and Hubbub” – hormones, trauma, and overuse

📌 Causes & Risk Factors
• Pregnancy (↑ relaxin = ligament laxity)
• Previous SPD in earlier pregnancies
• Multiple pregnancies, rapid labour, instrumental delivery
• Pelvic trauma or inflammatory conditions
• High BMI, poor pelvic muscle strength
• Occupations/activities involving repetitive pelvic strain

📌 Pathophysiology
• Relaxin → loosens ligaments → pelvic joint instability
• Uneven forces across pelvis cause micro-movement and pain at pubic symphysis
• May lead to separation or inflammation of joint
💡 Analogy: “A loose suspension bridge under strain”

📌 Differential Diagnosis
• Hip OA or labral tears
• Pelvic girdle pain
• Hernias (inguinal/femoral)
• UTIs or pelvic infections
• Stress fractures or referred lumbar pain

📌 Epidemiology (UK)
• Affects ~1 in 300 pregnancies
• Much rarer in non-pregnant individuals
• Often missed in primary care despite clear impact on function

📌 Clinical Features
• Pain over pubic bone radiating to groin/thighs
• Worsened by walking, stairs, turning in bed
• Clicking, grinding, waddling gait
• Difficulty weight-bearing, dressing, getting into car
💡 Mnemonic: “Waddling, Weight-bearing pain, and Weak pelvic control”

📌 Diagnosis
• Clinical diagnosis based on symptoms + physical exam
• Tenderness at pubic symphysis
• Positive single-leg stance or Patrick’s test
• Imaging (X-ray, US) only if red flags or to rule out other causes

📌 Management
🎯 Goals: Reduce pain, improve function, support pelvic stability
• Physiotherapy – pelvic floor, gluteal and core strength
• Pelvic support belts – external stability aid
• Paracetamol – 1st line for pain
• Opioids (short-term) – for severe cases with caution in pregnancy
• Night positioning advice – pillow between legs, side-sleeping
• Referral to obstetrics/orthopaedics if symptoms severe or ongoing postpartum

📌 Prognosis
✅ Most resolve after delivery as hormone levels fall
❗ Symptoms may persist postpartum or recur in future pregnancies
• Rare chronic pelvic instability or mobility issues

📌 Complications
• Chronic pelvic pain
• Functional limitations
• Postnatal depression (due to loss of mobility)
• Long-term pelvic floor dysfunction

👁️ MSRA Podcast: Blepharitis – Red, Sore Lids Explained

Let’s explore Blepharitis, a chronic eyelid inflammation that’s one of the most common causes of sore, irritated eyes seen in GP and ophthalmology clinics.

🧠 Definition & Types
• Inflammation of eyelid margins – usually bilateral and chronic
• Anterior = lash line (bacterial/seborrhoeic) → “A for At the lashes”
• Posterior = meibomian glands (MGD-related, rosacea) → “P for Poor oil production”

⚠️ Causes & Risk Factors
• Bacterial colonisation, seborrhoeic dermatitis
• MGD, dry eyes, rosacea, eczema, psoriasis
• Allergies, ageing, contact lens use, Demodex mites

🔬 Pathophysiology
• Debris/oil at lid margin → bacterial overgrowth → immune response

🎧 MSRA Podcast: Anterior Uveitis (Iritis) – Red Eye, Real Risk
A focused Deep Dive into anterior uveitis, the most common uveitis type in the UK. Perfect for MSRA revision, GP triage, or acute red eye cases.

🧠 What You’ll Learn
✅ Definition
• Inflammation of the anterior uveal tract (iris + ciliary body)
• Presents with unilateral red eye, photophobia, pain
• May be granulomatous (chronic/systemic) or non-granulomatous (acute/idiopathic)
🧠 Mnemonic: Mutton fat KPs → think systemic disease

⚠️ Key Associations
• Strong links: HLA-B27 (Ankylosing Spondylitis, Psoriatic Arthritis, IBD, Reactive Arthritis)
• Other: Sarcoidosis, Behçet’s, JIA, Herpes simplex, CMV, Syphilis, TB
🧠 Mnemonic: A-I-I-I – Autoimmune, Infectious, Iatrogenic, Idiopathic

🔬 Pathophysiology
• Immune-mediated, often due to molecular mimicry
• Triggers cytokine release → keratic precipitates, synechiae, flare, hypopyon

🔍 Differential Diagnosis
• Conjunctivitis, scleritis, acute glaucoma, herpes keratitis (no steroids!)
• Other uveitis types, trauma, lens-induced inflammation
🚨 Red flag: Dendritic ulcer on slit lamp = avoid steroids!

📊 Epidemiology
• Most common uveitis in the UK (25–50/100,000/year)
• Peaks age 20–50, slight male predominance (HLA-B27)
• JIA-related uveitis may be asymptomatic – screen regularly

👁️ Clinical Features
• Unilateral red eye, photophobia, blurred vision, lacrimation
• Miotic, irregular pupil, ciliary flush, hypopyon, keratic precipitates
🧠 Mnemonic: RIPP – Red eye, Irregular pupil, Photophobia, Pain

🧪 Diagnosis & Investigations
• Slit lamp: cells + flare in anterior chamber
• IOP may be low or high
• OCT: for macular oedema
• Investigate if recurrent, bilateral, granulomatous, or systemic symptoms
• Bloods: FBC, ESR, ACE, HLA-B27, ANA, RF, Syphilis, TB
• Imaging: CXR (sarcoidosis/TB)
• Infectious screen: HSV, CMV, VZV, toxoplasmosis, Lyme, HIV

💊 Management
• Urgent ophthalmology referral within 24 hours
• Cycloplegic drops (e.g. atropine) – relieve pain, prevent synechiae
• Topical corticosteroids (e.g. prednisolone) – reduce inflammation
❌ Do not start steroids in primary care unless advised
• If infectious: add antivirals/antibiotics
• Systemic immunosuppressants for chronic/refractory cases
• Monitor for glaucoma, macular oedema, cataracts with OCT + exams

📉 Prognosis
• Good with prompt treatment
• Risk of relapse, esp. in HLA-B27
• Chronic cases = higher risk of complications

🚨 Complications
• Glaucoma, cataracts, macular oedema, posterior synechiae
• Long-term: vision loss, optic nerve damage, retinal detachment, neovascularisation

🎧MSRA Podcast:Argyll-Robertson Pupil – A Small Sign with Big Implications

In today’s DeepDive, we explore the Argyll-Robertson pupil– a classic and high-yield neurological sign that can unlock insight intoserious underlying conditions like neurosyphilis.

This is the “light-near dissociation” you absolutely needto know for the MSRA.

🧠What is theArgyll-Robertson Pupil?

• Bilateral, small, irregular pupils

• Do not react to light

• But constrict normally to accommodation (near focus)

• Classic for neurosyphilis, but also seen in otherneurological conditions

🧠Mnemonic: “ARP” =Accommodation Reflex Present, Pupillary Reflex Absent

🔍Key Causes to Know

• Tertiary syphilis (neurosyphilis) – most commoncause

• Diabeticneuropathy

• Midbrain lesions(e.g., Parinaud syndrome)

• Alcoholic midbraindegeneration

• Encephalitis

• Multiple sclerosis

• Pineal glandtumours

🔬Pathophysiology – WhyDoes This Happen?

• Damage to the pretectal area of the midbrain

• Disrupts light reflex pathway

• Accommodation reflex pathway is either sparedor takes an alternate route

• A brilliantclinical example of how localised neurologicaldamage can dissociate reflexes

🧪DifferentialDiagnoses

Don’t forget to ruleout:

• Adie’s (tonic) pupil

• Horner’s syndrome (with ptosis and anhidrosis)

• Opioid overdose (pinpoint pupils)

• Pharmacologic causes – e.g. miotic agents

📊Epidemiology

• Rare in the modern UK due to earlydiagnosis/treatment of syphilis

• Still important tospot in undiagnosed or inadequately treatedlate syphilis

• May be seen in global health contexts, or in patients with complex neurological presentations

🔎Clinical Features

• Bilateral, small, irregular pupils

• Poor or absentlight reflex

• Normalconstriction to near stimulus

• No direct visualcomplaint – diagnosis based on clinicalexamination

🧪Investigations

• Detailed eye exam including light and near reflex testing

• Syphilis serology: treponemal-specific andnon-specific tests

• Neuroimaging (MRI) if other midbrain pathologysuspected

• Consider CSF analysis if neurosyphilis is suspected

💉Management

• Treat the underlying cause, not the pupil abnormalityitself

• For neurosyphilis:

– IV high-dose penicillin G is the treatment ofchoice

– Monitor for Jarisch-Herxheimer reaction

• Addressco-existing neurological or infectious complications

📈Prognosis &Complications

• ARP itself causes no direct harm

• But underlyingneurosyphilis can lead to:

– General paresis

– Tabes dorsalis

– Cognitiveimpairment

– Vision and hearingloss

• Early detectionand treatment improve outcomes

🧠Quick Summary – Whatto Remember

• ARP = small, irregular pupils, poor light response,good near response

• Strongly associated with neurosyphilis

• Test with light and accommodation reflexes

• Confirm with syphilis serology

• Manage the underlying cause, not the pupil itself

• MSRA loves classicsigns – and this one is gold

👁️ Cataracts – High-Yield Revision for the MSRA 👁️

Welcome to anotherDeep Dive! Today we’re focusing on one of the most common causes of vision lossworldwide – cataracts.

🧠 What you'll learn in this episode:

• Clear definition of cataracts: progressive clouding of the lens leading to blurry vision
• Why age is the biggest culprit, but how trauma, diabetes, steroids, UV exposure & smoking also play key roles
• How cataracts present: think gradual vision loss, glare sensitivity, faded colours, halos, frequent glasses changes
• Types of cataracts (nuclear, cortical, subcapsular) and how they differ
• How to diagnose them (visual acuity, slit lamp exam, red reflex check, dilated fundoscopy)
• Definitive management: cataract surgery with IOL implantation
• Prognosis: excellent with surgery, but untreated cataracts can lead to blindness
• Key complications post-op: posterior capsule opacification (PCO), infection (endophthalmitis), or raised IOP

📝 Memory Aids:

• 🔑 Mnemonic: AFMSS for risk factors – Age, Family history, Medical conditions (esp. diabetes), Sunlight, Smoking
• 🔍 Symptoms: BGLCDH – Blurred vision, Glare, Low-light difficulty, Colour fading, Double vision, Halos

🎯 MSRA Focus:

• Know when surgery is indicated (not just vision score – based on functional impact)
• Surgery is the only curative treatment – drops & glasses help symptoms but don’t reverse the disease
• Posterior capsule opacification is the most common post-op issue and is fixed with YAG laser

🌍 Did you know?

• Over 12 million people globally are blind due to cataracts
• In the UK, >50% of people over 65 have cataracts, and 70% of those over 85
• Cataract surgery is one of the most commonly performed surgeries worldwide

🎧Deep Dive: AllergicConjunctivitis – MSRA Ophthalmology Essentials

You know that itchy,watery, red-eye feeling—especially during spring or when your pet curls up nextto you? That’s where today’s deep dive begins. We're unpacking allergic conjunctivitis — what it is, whatcauses it, and how to manage it effectively, especially for your MSRA prep.

👁️What Is It?

An inflammation of the conjunctiva triggered byallergens like pollen, pet dander, or dust mites. It's your immune systemoverreacting to harmless substances.

🧬Pathophysiology

Exposure toallergens → IgE binds to mast cells →release of histamine and inflammatory mediators→ itching, redness, watering, and swelling.

📌Key Risk Factors

• Personal or familyhistory of atopy (eczema, asthma,allergic rhinitis)

• Seasonal pollenexposure (hay fever overlap)

• Indoor allergens(dust mites, pets)

• Contact lens use(risk of Giant Papillary Conjunctivitis)

🧠Symptoms & Signs

• Intense itching – the hallmark symptom

• Bilateral red, watery eyes

• Puffy eyelids,chemosis (conjunctival swelling), papillae under lids

• History ofseasonal allergy or atopic conditions

❗DifferentialDiagnosis

Don’t confuse itwith:

• Infective conjunctivitis (viral/bacterial –sticky discharge)

• Uveitis, keratitis (pain, photophobia, visionloss)

• Blepharitis, scleritis, glaucoma – especiallyif pain, photophobia, or unilateral

🔍 Always ask: Is it itchy or painful? Pain = red flag 🚨

📊Epidemiology

• Affects up to 40% of the population

• Common in childrenand young adults

• Oftenunderdiagnosed

• Peaks in spring/summer (pollen), but can be perennial (dust/pets)

🩺Diagnosis

✅ Primarily clinical

✅ Based on history + bilateral itch/redness

🔬 Investigations (if needed):

• Conjunctival swab(to exclude infection)

• Allergy testing(if severe/recurrent)

• Slit lamp exam(for papillae, corneal involvement)

• Fluoresceinstaining (if keratitis suspected)

💊Management (UKNICE-Based)

1️⃣Avoidance – limit allergen exposure

2️⃣Cool compresses +artificial tears

3️⃣Topicalantihistamines – fast symptom relief

4️⃣Mast cell stabilisers – prevent recurrence

5️⃣Oral antihistamines – useful if hay fever present

6️⃣Steroid eye drops – only under ophthalmology care

🚫 Avoid rubbing eyes – it worsens inflammation!

📈When to Refer

🔺 Severe or persistent symptoms

🔺 Need for topical steroids

🔺 Unclear diagnosis

🔺 Suspected sight-threatening causes (uveitis,keratitis, etc.)

📅Prognosis

✅ Excellent in most common forms(seasonal/perennial)

⚠️Vernal and atopickeratoconjunctivitis carry risk ofcorneal damage – need specialist input

✅ Vision usually well preserved with proper care

🧠MSRA Key Takeaways

• Itch = Allergy

• Bilateral, red,watery eyes = classic

• Atopy is a strongclue

• Rule out painful, unilateral, or vision-threateningcauses

• Topicalantihistamines + stabilisers = 1st-line

• Refer if red flagsor steroid needed

🎓 Mnemonic: ITCH = Intense Tearing, Chemosis, Hyperaemia

🧰 Management: Avoid, Antihistamines, Artificial tears, Atropine(stabiliser)

📤 Referral if Pain, Photophobia, Poor vision

👁️‍🗨️ Age-related Macular Degeneration(AMD): The Fast Facts for MSRA 🚦

🔍 What is AMD?

• AMD = progressive degeneration of the macula (central retina) → central vision loss.
• #1 cause of severe visual impairment in older adults in the UK.

🧬 Types

• Dry (atrophic) AMD 🟡 (90%)
  Gradual loss, drusen (yellow deposits), slow atrophy.
• Wet (neovascular/exudative) AMD 💧 (10%)
  Rapid, severe vision loss. Caused by leaky, abnormal new blood vessels under the macula.

🧑‍⚕️ Causes & Risks

• Age ↑ (biggest risk)
• Genetics (family history)
• Smoking 🚬 (x2-5 risk & more severe)
• CV: Hypertension, high cholesterol, diabetes
• UV light ☀️, poor diet, obesity, Caucasian ethnicity, female gender

⚡️ Pathophysiology

• Dry: Drusen accumulate → damage retinal pigment epithelium (RPE) → photoreceptor loss.
• Wet: Choroidal neovascularization → vessels leak fluid/blood → fast central vision loss.

🤔 Differentials

• Diabetic maculopathy, myopic degeneration, CSR, macular dystrophies, macular hole, retinal vein/artery occlusion, late glaucoma, stroke/tumor (visual pathway), cataract, posterior vitreous detachment.

📊 Epidemiology

• Prevalence increases steeply with age:
  2.4% (>50y), 5% (>65y), 12% (>80y)
• 90% dry, 10% wet—but wet AMD causes most severe vision loss.

🛑 Symptoms

• Blurry or distorted central vision (trouble reading, faces)
• Metamorphopsia (straight lines bend)
• Central scotoma (dark/empty spot)
• Loss of contrast/colour, glare
• Charles Bonnet syndrome (visual hallucinations)

🩺 Diagnosis

• Fundoscopy: Drusen (dry); subretinal fluid, hemorrhage, exudates (wet)
• OCT (Optical Coherence Tomography): Essential for detecting retinal changes/fluid
• Fluorescein angiography: For diagnosis/planning wet AMD
• Amsler grid: Self-test for distortion

💊 Management

Dry AMD

• No cure—but slow progression:
• Lifestyle: Stop smoking, healthy diet (leafy greens, lutein)
• Supplements: AREDS2 (antioxidants, zinc, lutein, zeaxanthin)
• Low vision aids, regular monitoring

Wet AMD

• Urgent referral!
• Anti-VEGF injections (e.g., ranibizumab, aflibercept, bevacizumab)
• 🏥 Given monthly, then as needed based on OCT.
• Rare: Photodynamic therapy (PDT), laser (uncommon now)
• Supportive: Visual aids, driving advice, support groups

🧨 Complications

• Central vision loss → legal blindness
• Wet AMD: Rapid progression, subretinal hemorrhage, retinal detachment
• Anti-VEGF: Infection, inflammation, rarely retinal detachment, IOP rise
• Mental health: Depression, social isolation, falls risk

🏁 Key Takeaways

• AMD = dry (slow, drusen) or wet (rapid, leaky vessels)
• Biggest risks: Age & smoking!
• Diagnosis = clinical + OCT
• Management:
• Dry: Lifestyle, AREDS2, monitor
• Wet: Urgent anti-VEGF injections
• Regular review needed—early detection = better vision!

🎧MSRA Deep Dive: AcuteIritis (Anterior Uveitis)

Suddenpainful red eye? Blurred vision? Sensitivity to light? 🚨 Let’s break down one of the most tested ophthalmology topics for theMSRA: acute iritis, also known as anterior uveitis.

In this episode, wecover everything you need to know in a concise, high-yield format perfect forfast revision — or helping a patient in clinic. Get the essential facts,mnemonics, red flags, and NICE-aligned management steps all in one go.

🧠Core Learning Points

📌Definition

• Acute iritis = inflammation of the anterior uveal tract (iris + ciliary body)
• Most common type of uveitis
• Rapid onset (within hours–days)

📌Symptoms

🔺 Painful red eye

🔺 Photophobia (light sensitivity)

🔺 Blurred vision

🔺 Watery eye, no discharge

🔺 Usually unilateral

📝Mnemonic: PURR

Painful red eye

Unilateral

Reduced vision

Reaction to light

📌Differentials to RuleOut

• 🌫️ Conjunctivitis – itchy, gritty, sticky discharge
• 🌈 Acute angle closure glaucoma – severe pain, halos, vomiting, firm eye
• 🌊 Keratitis – corneal damage
• 🧠 Posterior/Intermediate/Pan-uveitis – different ocular zones

📌Causes

🔹 Idiopathic (most common)

🔹Autoimmune diseases:

• Ankylosing spondylitis
• Reactive arthritis
• Psoriatic arthritis
• IBD (Crohn’s/UC)
  🔹 Infections: HSV, TB, syphilis, HIV
  🔹 Trauma or post-op
  🔹 HLA-B27 associated (↑ risk)

📌Investigations

🧪Slit lamp exam – shows cells & protein flare in anteriorchamber

📏 Check intraocular pressure (to exclude secondaryglaucoma)

🧬 Bloods if: recurrent, bilateral, systemic symptoms

• HLA-B27
• ESR/CRP
• Autoimmune panel
  🩻 Chest X-ray – if sarcoidosis/TB suspected

📌Management

💧Topicalcorticosteroids (e.g. prednisolonedrops) – reduce inflammation

💧Cycloplegic drops (e.g. atropine) – dilate pupil, reduce pain &prevent synechiae

📉IOP-lowering drops – if raised pressure

📅 Taper steroids over 6+ weeks

🔁 Regular follow-up to prevent complications

📌Complications

🚨 Posterior synechiae (iris sticking to lens)

🚨 Secondary glaucoma

🚨 Cataracts (from inflammation/steroids)

🚨 Chronic uveitis or vision loss (if not treated)

📌Prognosis

👍 Excellent with prompt treatment

⚠️ Risk of recurrence (especially in HLA-B27+)

🩺 Long-term follow-up often needed

💡Patient Tips

• Don’t drive if vision is affected
• Stick to prescribed drop regimen
• Seek help quickly for any return of symptoms
