Purpose: To investigate the relationship between axial myopia and visual deprivation in patients with cataracts in their youth.Methods: Forty myopic eyes of 25 cases had long deprivation of form vision due to cataracts during their youth. The axial length was measured by A-Scan ultrasound.Results: The axial length is 2-6mm (mean: 3. 7mm) longer than the other eyes in 10 patients with unilateral cataracts. Fifteen cases with bilateral cataracts had 25-29mm of axial length (mean of the right eyes 26-8mm and the left eyes: 26. 7mm). Six cases with unilateral cataract had traumatic histotry at age from 2-9 years (mean: 5. 1 years) and the duration of visual deprivation due to cataract was from 8 to 30 years (mean; 12 years). Thirteen cases with dilateral congenital cataract had 17- 4 years(from 3 to 37 years) of visual deprivation. Concusion: The deprivation of form vision due to cataracts in childhood leads to in crease in axial length and myopia. Eye Science 1996; 12: 135- 137.
