Objective:

To investigate the anatomical features of fellow eyes in patients with primary angle-closure glaucoma (PACG) and assess their risk for angle closure.

Approach:

Key Findings:

• Both fellow-eye groups (F-APAC and F-CPACG) showed a more crowded anterior segment compared to healthy controls.
• F-APAC eyes had smaller ACD, narrower angle metrics, and higher lens vault compared to healthy eyes.
• F-CPACG eyes also exhibited reduced ACD and angle parameters, with increased lens vault and iris curvature.

Interpretation:

The fellow eye in unilateral PACG presents anatomical features indicative of high risk for angle closure, even in the absence of detectable optic nerve damage.

Limitations:

• Small sample size.
• Cross-sectional design limits causal inferences.

Conclusion:

Careful assessment of the fellow eye is crucial, as anatomical features like lens vault may help differentiate between acute and chronic angle-closure predispositions.
