Ramazan Orucunun Vasküler Retina ve Ön Kamara Parametrelerine Etkisi

Amaç: Bu çalışmada Ramazan orucunun vasküler retina ve ön kamara parametreleri üzerindeki etkilerini değerlendirmek amaçlanmıştır Gereç ve Yöntemler: Mayıs—Temmuz 2017 döneminde kliniğimize gelen 30 gönüllünün (15 erkek, 15 kadın) 60 sağlıklı gözü çalışmaya alındı. Göz içi basıncı (GİB), ön kamara hacmi (ÖKH), santral kornea kalınlığı (SSK), santral makula kalınlığı (SMK), optik disk retina sinir lifi tabakası (OD-RSLT) ve subfoveal koroit kalınlığı (SFKK) ölçümü ile retinal vasküler analiz (santral retinal arter damar değeri [SRAD], santral retinal ven damar değeri [SRVD] ve arter/ven oranı [AVO]) gerçekleştirildi. Ölçümler Ramazan ayının son 5 gününde orucun 4. ve 12. saatlerinde, iftardan 1 saat sonra ve Ramazan ayından 1 ay sonra tekrarlandı. Bulgular: Katılımcı yaş ortalaması 29,30±8,12 yıl idi. Orucun 12. saatindeki SFKK, SRAD ve SRVD değerleri Ramazan ayından 1 ay sonra ölçülen değerlere kıyasla istatistiksel olarak anlamlı şekilde daha düşüktü (sırasıyla p=0,033; p=0,020; p=0,025). Fakat GİB, ÖKH, SSK, SMK, OD-RSLT ve AVO değerlerinde istatistiksel olarak anlamlı bir değişiklik gözlenmedi. Tartışma ve Sonuç: On iki saat veya daha uzun süre oruç tutmanın retinal damar değerlerinde ve koroit kalınlığında değişiklere yol açtığı saptanmıştır.

Effects of Ramadan Fasting on Retinal Vascular and Anterior Chamber Parameters

Aim: In this study, we aimed to evaluate the effects of Ramadan fasting on retinal vascular andanterior chamber parameters.Materials and Methods: The study included 60 healthy eyes of 30 volunteers (15 males, 15 females) who visited our clinic between May and July 2017. We performed measurements of intraocular pressure (IOP), anterior chamber volume (ACV), central corneal thickness (CCT), centralmacular thickness (CMT), optic disc retinal nerve fiber layer (OD-RNFL) and subfoveal choroidalthickness (SFCT) and retinal vascular analysis (the central retinal artery equivalent [CRAE], central retinal vein equivalent [CRVE], and artery-to-vein ratio [AVR]). The measurements wererepeated in the 4th and 12th hours of the daily fasting period and 1st postprandial hour on the last5 days of the Ramadan month, and one month after the Ramadan month.Results: The mean participant age was 29.30±8.12 years. The twelfth-hour SFCT, CRAE, andCRVE measurements were statistically significantly lower than the values measured one monthafter Ramadan (p=0.033, p=0.020, p=0.025, respectively). However, no statistically significantdifference was observed in the IOP, ACV, CCT, CMT, OD-RNFL, and AVR measurements.Discussion and Conclusion: We found that fasting for 12 hours or longer caused changes inretinal vessel diameter and choroidal thickness.
