Which describes the signs of primary closed-angle glaucoma?

• A. Diffuse Corneal Edema, Mydriasis, Episcleral Injection, Blepharospasm, High IOP
• B. Cloudy Cornea With Halos Around Lights
• C. Painless Red Eye With Itching
• D. Subconjunctival Hemorrhage

Answer: (A)

The main idea here is recognizing the cluster of signs that come with an acute rise in intraocular pressure from a blocked drainage angle. In an acute primary angle-closure attack, you’d expect a painful, red eye with a dilated pupil and corneal edema that makes the cornea look hazy. The eye is intensely red (episcleral injection) and the person often grimaces or keeps the eye closed (blepharospasm) because of the pain. The defining feature is a very high intraocular pressure, which fits with this presentation.

This combination—diffuse corneal edema, a dilated pupil, red eye with scleral injection, and painful ocular guarding along with markedly elevated IOP—best matches the signs of an acute angle-closure glaucoma. Other options describe symptoms more typical of non-glaucoma conditions (like a painless itchy red eye or a subconjunctival hemorrhage), or only partial features, and don’t convey the full acute attack picture.
