Abstract (2. Language): 
Purpose: To reveal the effect of intensive reading on myopic development in secondary school children with emmetropic eyes. Methods: Both eyes of 77 male children (n = 97) with mean age of 12.70 years and mean 6 hours of reading (Group 1) were compared prospectively with the eyes of 36 children (n = 72) with mean age of 13.31 years without reading (Group 2) by means of cycloplegic refraction and ultrasonic biometric measurements at intervals of 18 months. Results: Myopic shift was present in 68 (72.3%) of 97 eyes by means ofcyclopleg ic refraction in Group 1. The mean anterior chamber depth (ACD), axial length (ALX), and keratometric (K) readings were sign if cantly higher after 18 months than first measurements (p = .0001 for all) in Group 1. There were no any statistically significant differences between two measurements of these parameters in Group 2 except increasing in keratometric readings. Conclusion: Our preliminary results show that reading and writing, one of the important environmental factor, causes refract ve myop c sh ft n emmetrop c male schoolch ldren, and is related with statistically signifcant increase in both ALX and K readings.

Abstract (Original Language): 
Amaç: Emetrop gözlerde yoğun okumanın miyopi gelişimi üzerindeki etkisinin 7 yıl süreli prospektif araştırılması. Metod: Yaş ortalamaları 12.70 olan, günde ortalama 6 saat okuma-yakın çalışma yapan 77 erkek ortaokul öğrencisinin 97 gözü ile (l.Grup), yaş ortalamaları 13.31 olan, okumayan ve sanayi mesleklerinde çalışan 36 çırağın 72 gözü (2.Grup=kontrol)18 ay arayla sikloplejik refraksiyon (SKP-R) ve ultrason i k biyometri k ölçümler yapılarak karşılaştırıldı. Bulgular: Birinci grupta sikloplejik refraksiyona göre 97 gözün 68 (%72.3)'inde miyopiye kayma oldu. Yine l.Grupta 18 ayarayla alınan SKP-R, keratometre (K), ön kamara derinliği (ÖKD) ve aksiyel uzunluk (AU) ölçümlerinde anlamlı artış vardı (her üç değer için p=0.0001). İkinci grupta se, K değerler ndek artış dışında hem refraks yondak hem de biyometrik parametrelerdeki fark anlamsızdı. Sonuç: Çalışmamızın ön sonuçları, öneml b r çevresel faktör olan okuma-yazmanın emetrop öğrencilerde miyopi yönünde refraksiyon değişimi yaptığını ve bu değişimin hem ÖKD ve AU hem de K değerindeki artma ile birlikte olduğunu göstermştr.
