Ge reç ve Yön tem: Okmeydanı Eğitim ve Araştırma Hastanesi Göz Hastalıkları Kliniğinde fakoemülsifikasyon tekniği ile katarakt cerrahisi geçirmiş 65 hastanın 99 gözü çalışmamıza dahil edildi. Tüm hastaların ameliyat öncesi ve ameliyat sonrası birinci gün, birinci hafta, birinci ay ve üçüncü ay fovea kalınlıkları, maküla hacmi ve ortalama maküla kalınlıkları OKT ile ölçüldü. Bulgular: Bu çalışmada KMÖ insidansı %3 olarak bulundu. Hastaların OKT ile yapılan ölçümlerinde ortalama fovea kalınlıkları ameliyat öncesi 250,4 (±18,5) μm, ameliyat sonrası birinci gün 252,08 (±23,2) μm, birinci hafta 261,4 (±27,8) μm, birinci ay 270,6 (±44,4) μm, üçüncü ay 265,4 (±41,6) μm olarak belirlendi. Ameliyat öncesi sonuçlar ile birinci hafta, birinci ay, üçüncü ay sonuçları arasında,birinci hafta ile birinci ay, üçüncü ay değerleri arasında istatistiksel olarak anlamlı fark bulunmuştur (p<0,01). Olguların 44'ünde (%44,4) kalınlık artışı tespit edilmiştir. Maküladaki kalınlık artışı en çok parafoveal bölgede meydana gelmiştir. Ameliyat esnasında görülen iris travması, arka kapsül açılması gibi zorlukların KMÖ gelişme riskini arttırdığı bulunmuştur (p=0,001). Sonuçlar: Katarakt cerrahisi sonrası subklinik maküla kalınlık artışı birinci haftada başlayıp, birinci ayda maksimum değerlere ulaşmaktadır. Özellikle komplike olan katarakt ameliyatlarında sonra KMÖ görülme sıklığı arttığından dolayı bu hastalar OKT ile yakın takip edilmelidir.

Ma te ri als and Met hods: This study included 99 eyes of 65 patients who underwent phacoemulsification surgery in Okmeydanı Training and Research Hospital, Department of Ophthalmology. Foveal thickness, macular volume, and mean macular thickness were measured by OCT preoperatively and at 1 st day, 1 st week, 1 st , and 3 rd months postoperatively. Re sults: In this study, the incidence of postoperative CME was 3%. The mean central foveal thickness was preoperatively 250.4 (±18.5) μm, and postoperatively was 252.08 (±23.2) μm at 1st day, 261.4 (±27.8) μm at 1st week, 270.6 (±44.4) μm at 1st month, and 265.4 (±41.6) μm at 3 rd month. The statistically significant increase in foveal thickness was defined between preoperative and 1st week, 1st month, 3 rd month as well as between 1st week, 1st month, and 3rd month (p<0.01). Increase in macular thickness was demonstrated in 44 eyes (44.4%) which was most frequently located in the parafoveal region. Intraoperative complications like iris trauma, posterior capsule tear, and vitreous loss were increased risk of CME (p=0.001). Conclusion: Subclinical macular thickness increment begins at 1st week and reaches maximum point at 1st month. Incidence of CME increased in patients who had a complicated cataract surgery, so they should be followed closely by OCT.

Materials and Methods: In all, 44 eyes of 44 patients who underwent PPV by one surgeon were evaluated with Pentacam preoperatively, first week, and first month after surgery. The patients were divided into two groups, eyes with silicone injection after PPV and eyes with PPV and no endotamponade. Main outcome measures were preoperative and postoperative anterior chamber volume (ACV), anterior chamber depth (ACD), anterior chamber angle (ACA), and central corneal thickness (CCT) obtained with pentacam. Results: Each group consisted of 22 patients. In both groups no significant difference was detected among preop and postop changes in ACV and ACA values (P > 0.05). The increase in ACD in silicone oil-injected group and the decrease in ACD in PPV group at postop 1 week were statistically significant (P < 0.05). The increase in CCT in silicone oil-injected group at postop 1 week and then decrease in postop 1 month were also significant (P < 0.05). Surgically induced astigmatism (SIA) was 3.7 Dioptry (D) in silicone oil-injected group and 2.4 D in PPV group at postop 1 week. SIA decreased to 1.7 D and 1.5 D, respectively, at postop 1 month. Changes in SIA were significant (P < 0.05). Conclusion: PPV effects cornea and anterior segment. Changes in cornea and anterior segment after PPV seem to return to preoperative values among 1 month after surgery.
