Review Of Related Disease (RRD) 5 Practice Exam

Which of the following is commonly present in acute angle-closure glaucoma?

Sudden-onset severe eye pain Red eye, corneal edema Halos around lights Mid-dilated pupil

Correct Answer:

Halos around lights

Explanation:

Halos around lights are commonly present in an acute angle-closure glaucoma because the sudden rise in intraocular pressure causes corneal edema, which diffuses light and creates visible halos around light sources. This edema distorts the refractive surface of the cornea, making rings around lights a noticeable symptom for patients during an acute attack. Along with halos, you often see a very painful, red eye and a mid-dilated pupil, and patients may report blurred vision or nausea. These signs together reflect the abrupt angle closure and elevated pressure, but halos around lights stand out as a distinctive, patient-reported clue that points to an acute attack.
