ABSTRACT
 Objective: The aim of this study was to investigate the changes according to age in anterior segment parameters measured by Galilei Dual Scheimpflug Analyzer. Material and Methods: Healthy subjects were recruited and classified into seven groups according to age. Group 1 consisted of subjects whose ages ranged between 5 and 10 years. Group 2, 3, 4, 5, 6, 7 consisted of subjects who were in their second, third, forth, fifth, sixth and seventh decades, respectively. After a detailed examination, anterior segment parameters were assessed by using Galilei Dual Scheimpflug Analyzer. The following parameters were obtained from topographic and pachymetric maps for analysis: anterior chamber angle (ACA), anterior chamber depth (ACD), anterior chamber volume (ACV), central corneal thickness (CCT), pupil diameter (PD) and corneal horizontal diameter (CHD). Statistical analysis was performed by using SPSS for Windows version 23.0. Results: The age of subjects ranged between 5 and 67 years. Of 229 subjects, 152 (66.4%) were female and 77 (33.6%) were male. The decrease in CCT, CHD, PD, ACD and ACA with age was statistically significant and a negative correlation was present (p=0.000). Except Group 1, the decline in ACV by increasing age was statistically significant and a negative correlation was present [r (458) =-0.34. p=0.000]. Conclusion: All anterior segment parameters except mean ACV measured by Galilei Dual Scheimpflug Analyzer were found to decline with age and mean ACD achieved to adult size till the beginning of the second decade.

ÖZET
 Amaç: Yaşla beraber ön segment parametrelerindeki değişimin Galilei Dual Scheimpflug Topografi ile değerlendirilmesi. Gereç ve Yöntemler: Çalışmaya sağlıklı denekler alınarak yaşlarına göre 7 gruba ayrıldı. Grup 1'deki deneklerin yaşları 5 ile 10 arasında idi. Grup 2, 3, 4, 5, 6 ve 7 ise yaşları sırasıyla ikinci, üçüncü, dördüncü, beşinci, altıncı ve yedinci on yıllarında olan deneklerden oluşturuldu. Detaylı göz muayenesinden sonra Galilei Dual Scheimpflug Topografi ile ön segment parametreleri değerlendirildi. Ön kamara açısı (ÖKA), ön kamara derinliği (ÖKD), ön kamara hacmi (ÖKH), merkezi kornea kalınlığı (MKK), pupilla çapı (PÇ) ve horizontal kornea çapı (KÇ) değerleri topografik ve pakimetrik haritalar incelenerek değerlendirildi. İstatistiksel analiz SPSS 23,0 programı ile yapıldı. Bulgular: Çalışmaya katılan 229 deneğin yaşları 5 ile 67 arasında değişmekte ve 152'si (%66,4) kadın, 77'si (%33,6) ise erkekti. Analiz sonucunda MKK, KÇ, PÇ, ÖKD ve ÖKA yaşla beraber azalmakta ve yaş ile bu değerler arasında istatistiksel olarak negatif korelasyon mevcuttu (p=0,000). ÖKH'de ise Grup 1 hariç diğer gruplar arasında yaşla beraber düşme olduğu gözlenmiş ve istatistiksel olarak negatif korelasyon bulunmuştur [r (458) =-0,34. p=0,000]. Sonuç: Galilei Dual Scheimpflug topografi ile ortalama ÖKH hariç tüm ön segment parametreleri yaşla birlikte azalmıştır. ÖKD'nin ikinci on yıldan itibaren erişkin boyutuna ulaştığı gözlenmiştir.
