Comparative study of anisometropic amblyopia treatment with spectacles alone and combined spectacles with patching
Purpose: To compare duration and amount of improvement with spectacles alone and spectacles with patching in anisometropic amblyopia.
Study Design: Prospective comparative interventional study
Methods: This prospective study was conducted at Department of Ophthalmology GMC Doda ,GMC Rajori, GMC Handwara , GMC Anatnag and District hospital pulwama J&K for period of five years. Difference in BCVA of 2 snellen lines or more in absence of any structural abnormality or visual pathway was considered indicative of amblyopia.
Inclusion criteria: Unilateral amblyopia, V/A < 6/9, Age 4 to 10 years, Anisometropia > 1D
Exclusion criteria: Stimulus deprivation amblyopia, Age <4 & >10 years, Bilateral Amblyopia, Already treated or under treatment amblyopia. 68 Amblyopic children were either treated with spectacles alone or with combined spectacle and patching. Follow up was done after every 2 months.
Results: Among 68 amblyopic children 30 were treated with spectacles alone and 38 were treated with combined spectacles and patching. Mean age at start of treatment in former was 6.2 +/-2.3 and 5.8 +/- 2.6 in combined group. Final V/A after treatment was 20/40 and 20/25 respectively among two groups. Mean time of amblyopia improvement was 7.3 +/- 4.1 and 6.2 +/- 3.5 in spectacles alone and combined spectacles and patching respectively.
Conclusion: Amblyopic children treated with combined spectacles and patching showed better results in amount as well as duration of treatment than those treated with spectacles alone.
