Abstract

Purpose: To determine the effect of the optic cup on the visual field in normal population and to evaluate age dependent differences in this relation. Material and Methods: Three-dimensional optic nerve head analysis and standart perimetric analysis of both eyes of 329 healthy subjects with no systemic and ocular problems (other than refractive error) was performed using a confocal scanning laser ophthalmoscope, HRT II (Heidelberg Retinal Tomograph II, Software Version 1.5, Heidelberg Engineering, Heidelberg, Germany) and Model-II Humphrey- 750 perimetry instrument, respectively. Disc area, cup area, linear cup to disc ratio (LCD), cup to disc area ratio (CDA), the visual field mean sen-sitivity(MS) and the mean defect(MD) were calculated. The standard achromatic perimetric analysis (SAP) was performed using SITA Standard central 30-2 program. Subjects were divided into six age groups as 20-29, 30-39, 40-49, 50-59, 60- 69 and 70-79 years. Subjects were also divided into six groups with respect to their LCD ranging between 0 to 0,6. The relation of the visual field MS with the optic nerve head cup parameters of all age groups were compared. Results: The mean age of the subjects (177 males, 152 females) was 48,3 ± 19,8 years (ranged 20-76 years). The mean disc area of the subjects 2,08 ± 0,39 mm2 (ranged 1,58 - 4,78 mm2). The mean visual field MS was 29,6 ±1,2 dB. LCD ratio was found to have a negative correlation with the disc area (r:-0,44, p

Özet

Amaç: Normal toplumda optik çukur konfigürasyonunun görme alanı duyarlılığına etkisinin belirlenmesi ve yaşa göre bu ilişkilerdeki farklılıkların ortaya konulması. Gereç ve Yöntem: Sistemik ve kırma kusuru dışında göz problemi olmayan sağlıklı 329 olgunun her 2 gözüne, konfokal tarayıcı laser oftalmoskop, HRT II (Heidelberg Retinal Tomograph II, Software Version 1.5, Heidelberg Engineering, Heidelberg, Germany) ile üç boyutlu optik sinir başı topografik analizi yapılarak disk alanı (DA), çukur alanı, lineer çukur/disk (LCD) oranı, çukur/ disk alanı (CDA) oranları hesaplandı. Tüm gözlerin model-II Humphrey-750 perimetri cihazıyla santral 30° SITA Standart algoritmasıyla görme alanı analizleri gerçekleştirilerek görme alanı ortalama duyarlılıkları (MS) ve ortalama sapma değerleri hesaplandı. Olgular yaşlarına göre altı gruba bölündüler (20-29, 30-39, 40-49, 50-59, 60-69, ve 70-79 yaş). Olgular LCD oranlarına göre 0.0-0.6 arasında olmak üzere de altı ayrı gruba bölündüler. Her yaş grubunda bulunan bireylerin görme alanı MS değerlerinin optik sinir başı LCD ve CDA oranı parametrelerine göre ilişkileri karşılaştırıldı. Bulgular: Olguların (177 erkek, 152 bayan) ortalama yaşı 48,3±19,8 yıl'dı (min-maks: 20-76 yıl). Olguların ortalama disk alanı 2,08 ± 0,39 mm2 (min-maks, 1,58 - 4,78 mm2) olarak bulundu. Görme alanı ortalama duyarlılığı 29,6 ± 1,2 dB olarak saptandı. LCD oranı, optik disk alanıyla yüksek düzeyde ilişkili olduğu saptandı. LCD ile görme alanı MS değerlerinin ters yönde ilişkili olduğu bulundu (r:-0,44, p
