Aim: To evaluate the role of age on the success of occlusion treatment in strabismic amblyopia.Institution: SSK Ankara Eye Disease Hospital.Materials and Method: Data, related to the cases with the diagnosis of accomodative or infantile esotropia and who received occlusion therapy for strabismic amblyopia in the strabismus department of our clinic from January 1995 to January 2000, were gathered retrospectively. Cases were grouped into three according to their age: 4 years and below (Group 1), 5-6 years (Group 2) and 7 and above (Group 3). LogMAR equivalents of the visual acuities of better and amblyopic eyes, visual acuity differences between the eyes before and after the treatment and visual acuity changes that occurred in the eyes during treatment and follow-up period were compared among the groups. Incidences of amblyopia resolution and recurrences in the groups were also compared.Results: There was a statistically insignificant increase in the treatment time as the age of the group increased (p=0.537). Increase in visual acuity in the first, second and third groups were found 0.40±0.31, 0.40±0.24, 0.35±0.27 logMAR respectively and they were found similar statistically (p=0.685). Resolution rates of amblyopia in the groups were found 67%, 78% and 58%. They were also found statistically not different (p=0.221). On the other hand amblyopia recurrences were found statistically more frequent in the youngest group (p=0.016). As a consequence of this regression, final success rates at the end of follow-up period changed and they were found 41%, 72% and 45% respectively. Occlusion treatment of the amblyopia was found most effective at the age of 5-6 years (p=0.012).Conclusion: We could say that occlusion treatment in amblyopia could be most effectively applied at the age of 5-6 years. In the much younger group although visual acuity increase could occur more quickly, regression of this acquired acuity could also occur more quickly due to plasticity of the brains of these cases. More frequent follow-up of these cases during and after therapy could be appropriate. In the older groups although amblyopia resolution rates were found lower and treatment times longer, we could say it is worth to treat, looking at the success rates.Keywords: Amblyopia, Occlusion treatment, AgeTurkiye Klinikleri J Ophthalmol 2002, 11:189-194
