Altered anterior segment biometrics in cataract patients with retinitis pigmentosa: a propensity-matched analysis suggests patterns of zonular weakness.

ABSTRACT:

Purpose

To explore the spatial structure of the anterior segment biometrics in cataract patients with retinitis pigmentosa (RP).

Methods

This is a retrospective study. We conducted a propensity score matching analysis (1:3) on anterior segment data of RP patients and normal cataract patients who underwent cataract surgery from August 2023 to February 2025. Baseline variables (age, gender, axial length, and Pentacam Nucleus Staging (PNS) score) were balanced to compare the differences in anterior segment biometric measurements between the two groups.

Results

We analyzed the anterior segment data of 37 cataract patients with RP and 102 simple cataract patients. The RP group exhibited a thicker lens (p < 0.001), a more anterior lens position (p = 0.003), a
