Ellipsoid zone evaluation may predict outcomes after cataract surgery in retinitis pigmentosa

Posted on December 21, 2021

Patients with retinitis pigmentosa (RP) who had preserved foveal ellipsoid zone prior to cataract surgery had a better visual prognosis, according to a study.

In this retrospective, observational study, 64 patients with typical RP who underwent cataract surgery were followed up for ≥3 years post-surgery.

A total of 96 eyes underwent cataract surgery and were followed for an average of 5.8 ± 2.4 years. The mean pre-surgery BCVA was 0.64 ± 0.52 and the final post-surgery BCVA was 0.61 ± 0.67 (P = 0.57), with significant improvement after surgery observed only in eyes with preserved foveal ellipsoid zone (grade 3). At the final visit, there was a significant decrease in mean values of deviation, macular sensitivity and foveal sensitivity in the 62 eyes that received Humphrey Field Analyzer 10-2 tests compared with preoperative values. There was no significant change post-surgery in grade 3 eyes.
