ABSTRACT

Background: To evaluate the various factors associated with recurrence of Amblyopia. Methods:In this prospective observational study, 100 patient’s diagonised anisometropic and strabismic amblyopia. All patients were undergone squint workup and were treated with optical correction, occulusion therapy or penalization. Patients were divided three groups - group 1 age (4-7 year) , group 2 age(8-12 year), group 3 age(13-17 year) . Patients were followed upto 12 month and various factors assessed which could be responsible for amblyopia and compared between three group. Results:Recurrence of amblyopia was seen in 24% of patients which was more in group 1 & mixed amblyopia type (statically significant p < 0.05). Recurrence of amblyopia was found to be patients independent of binocular vision and mode of treatment. Recurrence and its relation with length and dose of occlusion therapy were significant those who were weaned off 6 hrs patching as compared 2 hrs patching. Recurrence of amblyopia was found to be more in those who improved five lines as compared to two lines with statistically significant p < 0.05. Recurrence was more in first 6 month as compared to last six month during follow up. Conclusion: Recurrence is more commonly seen between the ages of 4-7 yrs and those who with mixed amblyopia should be closely monitored during follow up. Occlusion therapy should be prescribed weaning off, it should not be abruptly stop. Since recurrence may occur even beyond 1 year hence, a longer follow up period would be advisable.
