Purpose: To determine the efficacy of treatment on visual outcomes in bilateral refractive myopic amblyopia according to the degree of amblyopia and myopia in children of 4-18 years of age-group.
Materials and Methods: This prospective interventional study enrolled 25 cases with bilateral myopia in the age group of 4-18yrs excluding those with organic cause. Thorough ocular examination carried out including subjective test, torch-light and slit-lamp examination, fundoscopy, cycloplegic refraction, wet retinoscopy,. Myopia not improving with best-corrected visual acuity[BCVA] selected and classified according to the degree of amblyopia. The Initial and final BCVA compared converted to log MAR scale for statistical analysis. Treatment planned according to degree of amblyopia and myopia were macular stimulation, occlusion, and combination of occlusion with macular stimulation and spectacle correction. Follow-up period was 1 year with initial weekly visits followed by monthly visits. Percentage improvement of visual acuity assessed in each patient.
Result: Among 25 cases, with respect to difference in amblyopia grade in BE, maximum mild amblyopia in 10 eyes improved with macular stimulation and 8 eyes of moderate-severe amblyopia improved with combination of macular stimulation and occlusion. P-value[0.01] is statistically significant with macular stimulation in LE.
Conclusion: Untreated refractive errors in myopic are more prone to develop bilateral amblyopia. Timely proper treatment and compliance are necessary for visual improvement.
