Abstract
Purpose:
To assess the efficacy of patching therapy in people with unilateral anisometropic amblyopia in adults.
Methods:
The research was conducted at Visifert Eye Clinic in Noida, India, from August 2023 to May 2024, involved 28 adults with unilateral anisometropic amblyopia. Those who were at least eighteen years old met the inclusion requirements, a spherical equivalent less than -3.00D, best habitual visual acuity between 0.3 logMAR and 1.0 logMAR in the amblyopic eye, and logMAR 0.2 or better in the fellow eye. Participants underwent cycloplegic refraction and were given corrective spectacles to wear for one month. If no improvement was observed, patching treatment commenced, involving 3 hours of daily occlusion for 8 weeks. Visual acuity was assessed at the start and end of the treatment.
Results:
Out of 28 subjects, vision improved in 26 (92.85%) and did not improve in 2 (7.14%) after 6 weeks of patching therapy. The 17-20 age group showed 100% improvement, 20-24 age group had 92.85% improvement, and the 25 and above age group had 50% improvement. The overall mean visual improvement was 1.03 ± 0.944 lines on the log MAR chart.
Conclusion:
The study demonstrates that patching therapy leads to significant visual acuity improvement in adults with unilateral anisometropic amblyopia in the 18-20 age group. The results demonstrate the possibility of patching therapy beyond childhood, despite the limited sample size, and reinforce the necessity for bigger sample sizes in future studies to corroborate these findings.
