Backgrounds and Objective: Pars Plana Vitrectomy (PPV) and epiretinal membrane (ERM) peeling is the standard surgical procedure of ERM surgery. However, the effect of adding Internal Limiting Membrane (ILM) peeling to the standard surgery on macular function and structure remains still controversial. This study was aimed at investigating the effect of ILM peeling on the macular function and structure in idiopathic ERM surgery. Method: Thirty-six eyes of 34 patients were evaluated in this prospective study. The patients were divided into two groups (ILM peeling and non-ILM peeling group). While the removal of ERM was undergone alone in 19 eyes, it was combined with ILM peeling in 17 eyes. Metamorphopsia scores Vertical Metamorphopsia (VM) and Horizontal Metamorphopsia (HM), were measured at preoperative and 4 months postoperatively. Results: There was a statistically significant decrease in metamorphopsia (VM and HM) scores in both groups after the surgery. However, no statistically significant difference was found between the two groups in terms of reduction in VM scores and HM scores after surgery. Conclusion: Our study indicated that ILM peeling combined with ERM did not affect metamorphopsia scores.

ÖZOn üç yaşında erkek hasta ilerleyici görme azlığı yakınmasıyla başvurdu. Semptomları 3 yıl önce başlamış ve son 2 yıldır kötüleşmişti. Aile öyküsünde benzer yakınmaya sahip birey yoktu. Travma, inflamatuvar veya infeksiyöz oküler hastalık öyküsü yoktu. Düzeltilmiş en iyi görme keskinliği her iki gözünde 0.3 idi. Refraksiyon her iki gözde +2.50 diyoptri idi. Yüksek çözünürlüklü optik koherens tomografi (OKT) incelemesinde bilateral foveal kesitlerde foveanın merkezinde nörosensöriyel retinanın geniş hiporeflektif kistoid boşluklar ile bölündüğü ve perifoveal alanda iç ve dış retinal tabakaların arasında küçük kistik boşlukların olduğu köprü formu vardı. Çalışmamızda, konjenital retinoskizis tanısı alan olgunun yüksek çözünürlüklü OKT bulguları incelendi. Ayrıca hastalığın yönetimiyle ilgili güncel gelişmeler sunuldu.Anahtar kelimeler: Konjenital retinoskizis, maküla, yüksek çözünürlüklü optik koherans tomografi ABSTRACTA 13-year-old-male patient presented with a complaint of progressive visual. His symptoms started 3 years ago and worsened within the past 2 years. There was no one with a family history of similar complaints. He had no previous history of trauma, inflammatory or infectious ocular disease. He had a best-corrected visual acuity of 0.3 in both eyes. Refraction was +2.50 diopters in both eyes. The foveal sections examined with high-resolution optical coherence tomography (OCT) demonstrated wide hyporeflective cystoid spaces that split the neurosensory retina at the center of the fovea and small cystic space that formed bridges between the outer and inner retinal layers in perifoveal area bilaterally. In our study high-resolution OCT findings in patient diagnosed with congenital retinoschisis were analyzed. Also, the current developments related to management of the disease were presented.
