Surgical outcomes of rhegmatogenous retinal detachment associated with ocular toxoplasmosis

To evaluate the anatomical and functional outcomes of surgical treatment of retinal detachment secondary to ocular toxoplasmosis.

A retrospective analysis of data from patients who had undergone vitreoretinal surgery for retinal detachment secondary to ocular toxoplasmosis was conducted. The parameters that were analyzed include surgical procedures, anatomical outcomes, visual acuity, and postoperative complications.

This study included 22 patients, of which 13 were female (59.1%). The mean age was 28.5 years (SD ± 14.5, range 12-78 years) and the follow-up period varied from 1 to 163 months (mean 64 months). The mean baseline best-corrected visual acuity (BCVA) was 2.0 logMAR (SD ± 1.0). A total of 31 surgeries were performed, and the retina was reattached in 15 patients (68.2%) immediately after the first surgery and in 20 patients (90.9%) at a later point. The mean postoperative BCVA improved to 1.3 logMAR (SD ± 0.9) (p<0.05). Nineteen patients (86.4%) underwent cataract surgery with intraocular lens implant, and 12 patients (60.0%) underwent silicone oil removal. Five patients (22.7%) exhibited elevated intraocular pressure, and 1 patient (4.5%) developed hypotonia.

Surgical treatment of retinal detachment secondary to ocular toxoplasmosis resulted in considerable anatomical and functional improvement. Although PPV with silicone oil injection demonstrated the best outcomes, it is not reasonable to conclude that this is the best surgical approach given the small number of patients included in this study.
