Abstract
INTRODUCTION: Amblyopia is one of the most common causes of visual impairment among children. They are susceptible to amblyopia from birth, till when their visual cortex completes its development. The reason for this is, the abnormal visual experience during early childhood, the critical period of visual development. The earlier, the onset of this abnormal visual experience, the greater the amblyopia. OBJECTIVES: 1. To assess improvement in compliance during occlusion therapy with counseling alone and using occlusion with low vision devices. 2. To assess improvement in vision and higher visual functions. METHODS: Children with unilateral amblyopia (old cases alreadywith less compliance and new cases), between 5-18 years, were included into the study, after an informed consent. Distant and near visual acuity, contrast sensitivity in each eye and stereopsis were measured. Counselling for occlusion and near activity during occlusion was given Occlusion compliance was assessed at 1,3 and 6 month as in the occlusion monitor book. Children with good compliance were advised to continue occlusion and those with moderate and poor compliance were taught occlusion with low vision devices. Data analysis – SSPS 23 statistics, Categorical variables – Percentage, Continuous variables –Mean, Standard deviation. RESULTS: Counselling had clinically significant occlusion compliance (84.93%) Mean vision and stereopsis improvement (log 0.72 to 0.57 and 2167.57 to 836.83) was statistically significant Contrast sensitivity improvement (log 0.88 to 1.05) was highly significant In the low vision device group, there was good improvement in compliance rate, vision, contrast sensitivity and stereopsis. CONCLUSION: With good counselling and good occlusion compliance vision and higher visual functions improved.
