Abstract
Purpose- The aim of the study is to compare visual functions of children with uncorrected amblyopia treated with different binocular I Pad games and/or patching. Methods- Children with untreated amblyopia were enrolled in this pilot study. Children were divided into three groups: children treated with patching only, children attributed to play binocular snake I Pad game with patching, children attributed to play binocular blocks I Pad game with patching. Visual acuity VA, refraction, stereo acuity test, and ocular alignment tests were performed for all participants in the first visit and 4 weeks after starting treatment. Visual functions were compared between both visits. Results- A total of 18 children with untreated amblyopia participated in this study. Children were divided into three groups: Group 1= 8 children treated with patching only, Group 2= 5 children attributed to play binocular snake I Pad game with patching, and Group 3= 5 children attributed to play binocular blocks I Pad game with patching. There was no significant difference (P > 0.05) in gender and age between the three groups. Children showed good compliance to all patching treatment and I pad games groups. After 4 weeks, Visual acuity was improved in all amblyopic children in the form of one line improvement in patching group, two lines with binocular snake I Pad game and three lines with binocular blocks I Pad game. Moreover, stereoacuity was improved in all groups with greatest advance in blocks games group followed by snake group then patching group. Conclusion- This study demonstrated great effectiveness of both snake, and blocks binocular I Pad games on visual functions improvement for treatment of amblyopia. These games can contribute with patching in achieving better VA and stereoacuity enhancement in a shorter duration than patching alone.
Highlights
Amblyopia (Lazy eye) was defined as “decreased vision in one or both eyes as a result of insufficient stimulation of the development of the visual system” [1]
Children with amblyopia were recruited from Pediatric ophthalmology clinic of a tertiary care hospital and were divided into three groups based on treatment: Group 1= 8 children treated with patching only, Group 2= 5 children attributed to play binocular snake I Pad game with patching, and Group 3= 5 children attributed to play binocular blocks I
Visual acuity was improved in all amblyopic children in the form of one line improvement in patching group, two lines with binocular snake I Pad game and three lines with binocular blocks I Pad game
Summary
Amblyopia (Lazy eye) was defined as “decreased vision in one or both eyes as a result of insufficient stimulation of the development of the visual system” [1]. It is clinically a change in the visual acuity between the two eyes that is equal or more to 0.2 log MAR. The highest prevalence of amblyopia is in Canada (4.7%), while the lowest prevalence of amblyopia was in Singapore (1.19%) [2,3,4,5,6] This variation of prevalence among different countries could be due to different vision screening programs used for pre-school children, which plays a major role in detecting different visual problems. Early treatment of the condition and preventing visual complications [2]
