Abstract

Objectives: To investigate the ideal time and reproducibility of anterior chamber flare measurements. Ma­te­ri­als and Met­hods: Anterior chamber flare measurements were performed with laser flaremetre device at 8 am to 45 volunteers and these measurements were repeated on the same day at 12 pm and 4 pm. Re­sults: Twenty-five (55.5%) of the volunteers were women and 20 (44.5%) were men; mean age was 28.67±7.40 (18-49) years. The mean anterior chamber flare measurements taken following the ophthalmologic examination were 5.94±1.41 foton/msn at 8 am, 5.65±1.45 foton/msn at 12 pm, and 5.79±1.20 foton/msn at 4 pm. No statistical difference was found between the measurements (p=0.08). Subgroup analysis according to eye color, revealed no significant difference between flare measurements in brown, hazel, and green eyes (p=0.21). Correlation analysis demonstrated association between age and all flare measurements within the day (r=0.24, p=0.03; r=0.41, p=0.01, r=0.27, p=0.01). Conclusion: No significant diurnal change was detected in the flare measurements of our study subjects but positive correlation with age was observed. Hence, all flare measurements within a day are reliable and have high repeatability in healthy subjects. (Turk J Ophthalmol 2015; 45: 52-5)

Özet

Amaç: Laser flaremetre cihazı ile yapılan ön kamara bulanıklık ölçümlerin ideal zamanı ve tekrarlanabilirliğinin araştırılması. Ge­reç ve Yön­tem: Kırk beş gönüllünün sabah saat 8.00da laser flaremetre cihazı ile ön kamara bulanıklık ölçümleri yapılmış ve bu ölçümler aynı gün saat 12.00 ve saat 16.00da tekrarlanmıştır. Bulgular: Gönüllülerin 25i (%55,5) kadın ve 20si (%44,5) erkekti ve ortalama yaşları 28,67±7,40 yıldı. Olguların oftalmolojik muayenelerini takiben alınan ortalama ön kamara bulanıklık ölçümleri sabah saat 8:00da 5,94±1,41 foton/msn, saat 12de 5,65±1,45 foton/msn, saat 16.00da 5,79±1,20 foton/msn idi. Ölçümler arasında anlamlı bir farklılık saptanmadı (p=0,08). Katılımcıların göz rengine göre yapılan alt grup analizinde de kahverengi, ela ve yeşil göz renkler arasında anlamlı bir farklılık bulunmamıştır (p=0,21). Korelasyon analizinde gün içinde alınan üç ölçümün de yaşla korele olduğu görülmüştür (r=0,24, p=0,03; r=0,41, p=0,01, r=0,27 p=0,01). Sonuç: Ön kamara bulanıklık ölçümlerinde sağlıklı bireylerde gün içerisinde anlamlı bir değişiklik saptanmamıştır ancak yaşla pozitif korelasyon göstermektedir. Bu nedenle gün içindeki tüm ölçümler güvenilirdir ve tekrarlanabilirliği yüksektir. (Turk J Ophthalmol 2015; 45: 52-5)
