MACULAR HOLE ASSOCIATED WITH TOXOPLASMOSIS: A SURGICAL CASE SERIES

There are currently limited data addressing the surgical outcomes of pars plana vitrectomy (PPV) in toxoplasmosis-related macular hole (tMH). We aim to report and discuss safety and efficacy of PPV for tMH.

Surgical case series (n = 11), with minimum postoperative follow-up time of 6 months. Consecutive patients who underwent PPV for tMH from 2013 to 2016 were included. Indications for surgery were: visual acuity ≥ 0.6 logarithm of the minimum angle of resolution (Snellen 20/80 or less), no intraocular inflammation for more than 6 months, extrafoveal toxoplasmosis scar, elevated tMH borders on optical coherence tomography, and patient agreement with surgery. Surgery was performed-PPV with epiretinal (if present) and internal limiting membrane peeling. Safety and efficacy of PPV for tMH were addressed by evaluating: 1) surgery-related complications and 2) visual acuity improvement.

A total of 11 patients (6 male), with a mean age of 33.2 ± 11.0 years were studied. Mean preoperative best-corrected visual acuity significantly improved from 1.10 ± 0.24 (Snellen 20/252) to 0.43 ± 0.18 logarithm of the minimum angle of resolution (Snellen 20/54) at last follow-up visit (P < 0.01). The rate of visual acuity improvement (i.e., a gain of at least three lines) and tMH closure was 100% for both. The only reported surgery-related complication was cataract in one case.

Our results suggest that PPV is a safe and effective option in tMH cases. A controlled, longitudinal study would contribute to confirm these findings.
