**Question:** Most common complication of Acute Anterior Uveitis is

A. Cataract
B. Glaucoma
C. Corneal Ulcer
D. Choroidal Neovascularization

**Correct Answer:** B. Glaucoma

**Core Concept:**
Acute Anterior Uveitis is a form of uveitis, an inflammatory condition affecting the middle layer of the eye known as the uvea. This condition is typically caused by an infection, autoimmune disorder, or an allergic reaction. When left untreated, acute anterior uveitis can lead to several complications, primarily affecting the eye's health and vision.

**Why the Correct Answer is Right:**
The most common complication of acute anterior uveitis is glaucoma. Glaucoma is a group of eye conditions characterized by increased intraocular pressure (IOP), which leads to damage to the optic nerve and subsequent vision loss. In acute anterior uveitis, the inflammation in the uveal tract can impair the aqueous humor drainage system, resulting in elevated IOP and the development of glaucoma.

**Why Each Wrong Option is Incorrect:**
A. Cataract: Acute anterior uveitis itself does not directly cause cataract formation. While inflammation can worsen an existing cataract, it is not the primary complication of acute anterior uveitis.

C. Corneal Ulcer: Corneal ulcers are typically caused by bacterial or viral infections, trauma, or other external factors. While acute anterior uveitis itself does not directly lead to corneal ulcers, it may facilitate the entry of pathogens into the eye, increasing the risk of corneal ulcers.

D. Choroidal Neovascularization (CNV): Choroidal neovascularization is a complication of various ocular conditions, such as age-related macular degeneration, but is not directly caused by acute anterior uveitis.

**Clinical Pearl:**
While acute anterior uveitis is a crucial diagnostic consideration in patients with eye inflammation, it is essential to differentiate between the primary condition and its potential complications, such as glaucoma, corneal ulcers, and choroidal neovascularization. Early recognition and management of these complications are crucial to preserve a patient's vision and eye health.
