To estimate effectiveness of internal limiting membrane pealing at patients with primary pigmentary degeneration of retina
Kazakh Research Institute of Eye Diseases
4 patients had been under observation. Among them 3 women and 1 man in age from 30 to 60 years (in average 46,3±5,7 years). In 3 cases there was a mixed stage and in 1 case there was – peripheral stage. Maximal corrected vision acuity (MCVA) before treatment comprised from 0.03 to 0.2 (in average 0,08±0,02). Thickness of the retina in the centre (TRC) before treatment comprised from 397 to 733 mk (in average 508,3±65мк) according to the OCT data. In all the cases structural changes of the retina and vitreous were observed in the macular area. In 2 cases myopic refraction and in 2 other cases hypermetropic refraction were observed. Posterior capsular cataract was diagnosed at all the patients. Intraocular pressure was compensated. All the patients had been operated: they had internal limiting membrane pealing with phaco
Operations and postoperative period passed within normal limits. Epiretinal membrane was abolished at all the patients intraoperatively, what was confirmed by OCT in postoperative period. MCVA after operation increased and comprised in average 0,2±0,07 (from 0,05 to 0,4). Thickness of the retina in the centre according to OCT data decreased and comprised in average 300,3 ±32 мc (from 263 to 393 мc)
Internal limiting membrane pealing can be considered as a variant of the rehabilitative treatment directed towards improvement and relative stabilization of visual functions at patients with primary pigmentary degeneration of retina and abnormal changes in macular area, associated with epiretinal fibrous proliferation.
