๐ Clinical Case Study:
A 60-year-old female presents with sudden, severe pain in her right eye, accompanied by blurred vision, halos around lights, headache, nausea, and vomiting. On exam, the eye is red, the pupil is mid-dilated and non-reactive, and the cornea is cloudy. What is the diagnosis?
๐ Options:
โข Option A: A. Acute angle-closure glaucoma
โข Option B: B. Primary open-angle glaucoma
โข Option C: C. Optic neuritis
โข Option D: D. Central retinal artery occlusion
โ
Correct Answer: Option A
๐ก Explanation:
Acute angle-closure glaucoma is an ophthalmic emergency caused by rapid blockage of the trabecular meshwork by the iris, leading to a sudden rise in intraocular pressure (IOP). Key signs include severe pain, red eye, mid-dilated non-reactive pupil, and cloudy cornea.
๐ง Mnemonic: Acute Glaucoma Triad
โข P โ Pain (severe, sudden, radiating to head)
โข R โ Red eye & mid-dilated pupil
โข C โ Cloudy cornea with high intraocular pressure
โ ๏ธ Exam Trap to Avoid:
Primary open-angle glaucoma is completely painless and asymptomatic ('silent thief of sight') until late visual field loss, whereas acute angle-closure glaucoma is highly painful.
