Anizometrik ambliyopide kapama tedavisinin farklı yaş gruplarındaki etkinliği

Bu çalışmada, anizometropik ambliyopili hastalara uygulanan kapama tedavisinin farklı yaş gruplarına göre etkinliği araştırıldı. Okul öncesi (4-6 yaş grubu) 15 hasta ve okul çağı (7-11 yaş grubu) 19 hasta olmak üzere anizometropik ambliyopi tanısı almış toplam 34 hastaya kapama tedavisi uygulandı. Günlük kapama süresi minimum 6 saat idi. Hastaların başlangıç, 1. ay, 3. ay ve 6. ay' da düzeltilmiş en iyi görme keskinliği ölçülerek, ambliyop gruplar birbirleriyle ve kontrollerle karşılaştırılarak değerlendirildi. Başlangıç görme düzeyleri bakımından, ambliyop okul öncesi ve 7-11 yaş grubu arasında istatistiksel anlamlı fark bulunmazken (P>0.05), ambliyop gruplarla aynı yaş kontroller arasında anlamlı fark vardı (P

The effectiveness of occlusion treatment on anisometric amblyopia in different age groups

The aim of this study was to investigate the efficacy of occlusion treatment on different age group patients with anisometropic amblyopia. Occlusion treatment was applied to 34 patients, 15 preschool children (age between 4-6 years), and 19 school age children (7-11 years). Daily duration of occlusion was minimum 6 hours. Best corrected visual acuity of patients was measured initially, at the end of 1st, 3rd and 6th months. Data belonging to amblyopia groups was compared with one another and with the controls. Initial visual acuity of two amblyopia groups were similar, however there was a significant difference between the amblyopia groups and the controls (P<0.05). Compared to the initial levels, statistically significant recovery was observed in the visual acuity of amblyopia groups measured at the 1st, 3rd and 6th months of treatment (P<0.05). Although no significant difference was found in visual acuity of two amblyopia subgroups 6 months after the completion of treatment, at post-treatment 6th month, amblyopia groups had better visual acuity compared to the controls. In conclusion, occlusion treatment improved the visual acuity in anisometropic amblyopia without a difference between preschool and school age groups.
