Abstract

Purpose: To evaluate preoperative visual acuity, central macular thickness, and photoreceptor inner segment/outer segment (IS/OS) line of patients operated on for primary epiretinal membrane and to investigate if these parameters are correlated with final visual acuity. Materials and Methods: Sixty eyes of 60 patients who were operated on for primary epiretinal membrane were included in the study. Preoperative and postoperative best corrected visual acuities (BCVA), central macular thickness (CMT), and optical coherence tomography (OCT) findings were evaluated retrospectively. Thirteen patients with preoperative visual acuity ≤0.1 comprised group 1 and 47 patients with visual acuity ≥0.2 comprised group 2. Results: The mean BCVA was 0.33±0.18 preoperatively and 0.47±0.24 (0.10-0.90) at 6 months postoperatively. This increase in BCVA was considered statistically significant (p=0.000). The mean CMT was 419.6±48.1 μm preoperatively and 366.9±55.8 μm at 6 months postoperatively. This decrease was found to be significant (p=0.000). When group 2 was compared to group 1, the mean age was lower and the final visual acuity was higher in group 2 (p=0.0000). Compared to 9 patients with irregular IS/OS bands, 51 patients with normal IS/OS bands had significantly higher VA and lower CMT (p=0.000) levels. Preoperative CMT was 419.6±48.1 and 6-month postoperative CMT was 366.9±55.8 μm. This decrease was found to be significant (p=0.000). Conclusion: Early surgical treatment of primary epiretinal membrane results in an increase in VA. This increase is significantly higher in patients with good preoperative VA, normal IS/OS line structure, and lower CMT.

Özet

Amaç: Primer epiretinal membran (ERM) nedeniyle cerrahi tedavi uygulanan hastaların ameliyat öncesi görme keskinliği, merkezi maküler kalınlık (MMK) ve fotoreseptör iç segment/ dış segment (IS/OS) bandının değerlendirilmesi ve bu faktörlerin son görme düzeyi üzerine olan etkilerinin araştırılmasıdır. Gereç ve Yöntem: 2009-2011 yılları arasında primer epiretinal membran nedeniyle ameliyat edilen 60 hastanın 60 gözü çalışmaya alındı. Hastaların ameliyat öncesi ve ameliyat sonrası 6. aydaki en iyi düzeltilmiş görme keskinlikleri (EDGK), optik koherens tomografi (OKT) bulguları ve MMK değerleri geriye dönük olarak incelendi. Ameliyat öncesi görme keskinliği ≤0.1 olan 13 olgu Grup 1, ≥0.2 olan 47 olgu Grup 2 olarak adlandırıldı. Bulgular: Olguların ameliyat öncesi görme keskinliği ortalama 0.33±0.18 (0.10-0.70), ameliyat sonrası 6. aydaki görme keskinliği ortalama 0.47±0.24 (0.10-0.90) olup, istatistiksel olarak anlamlı arttığı görüldü (p=0.000). Grup 2, grup 1’e kıyasla anlamlı olarak daha genç, görme keskinliğinin de anlamlı olarak daha yüksek olduğu bulundu (p=0.000). IS/OS bandı normal olan 51 olgunun, ameliyat öncesi ve sonrası görme keskinliği IS/OS bandı bozuk olan 9 olgudan anlamlı olarak daha iyiydi (p=0.000). Olguların ameliyat öncesi MMK ortalaması 419.6±48.1(340-560), ameliyat sonrası 6. ayda 366.9±55.8 (274-504) μm olup, istatistiksel olarak anlamlı azalma gözlendi (p=0.000). Sonuç: Erken dönemde yapılan ERM cerrahisi görme artışı ile sonuçlanmaktadır. Ameliyat öncesi görme keskinlikleri iyi olan, OKT’de IS/OS bandı normal olan ve MMK düşük olan hastalarda görme artışı daha fazla olmaktadır.
