Abstract
- Purpose
The long-term clinical outcomes of cataract surgery in patients with retinitis pigmentosa (RP) were evaluated.
Methods
A retrospective analysis of medical records was performed for patients who were diagnosed with RP and underwent cataract surgery. Preoperative best-corrected visual acuity (BCVA) was compared with BCVA at 1 month postoperatively and at the final visit. The proportion of patients with cystoid macular edema development or aggravation after surgery was evaluated, as was the proportion of patients with intraocular lens subluxation/dislocation. For patients who underwent optical coherence tomography, factors associated with a BCVA of 0.5 or better at 1 month were analyzed.
Results
In total, 133 eyes were included and the mean follow-up period was 58.7 months. The mean logarithm of minimal angle of resolution BCVA was 0.69 ± 0.65 at diagnosis. The BCVA was significantly improved to 0.51 ± 0.47 at 1 month postoperatively (p < 0.001). However, the BCVA at the final visit (0.70 ± 0.81) was similar to the baseline value (p = 1.000). Cystoid macular edema development or aggravation was noted in 8 eyes (6.0%) and intraocular lens subluxation/dislocation was noted in 4 eyes (3.0%). A subgroup analysis involving 108 eyes revealed that preoperative BCVA (p < 0.001) and ellipsoid zone status (p = 0.001) were associated with postoperative visual acuity.
Conclusions
Short-term outcomes of cataract surgery in patients with RP were comparatively good. However, long-term visual deterioration was noted with disease progression. Preoperative BCVA and ellipsoid zone status are useful markers for predicting short-term visual outcomes.
