| Summary: | Purpose:
The purpose of the study was to study the effectiveness of amblyopia treatment on distance best-corrected visual acuity (DBCVA), contrast sensitivity, and stereopsis in older children aged 9–18 years.
Subjects and Methods:
A prospective observational study was conducted on 54 amblyopic children (anisometropic, strabismic, combined, or ametropic amblyopes) from a tertiary care hospital. Children with ocular comorbidities were excluded. Spectacle correction was prescribed after cycloplegic refraction. Based on the improvement in distance visual acuity (VA) at the end of 4 weeks, the patients were divided into responder (improvement of ≥10 letters in DBCVA from baseline) or nonresponder (<10 letter improvement in DBCVA). Responders were continued on spectacle correction without patching. Nonresponders were prescribed patching according to Paediatric Eye Disease Investigator Group guidelines, and patients were followed up at an interval of 3, 6, and 12 months. Best-corrected distance VA (by LogMAR Chart), stereoacuity (by TNO test), and contrast sensitivity (by Pelli–Robson chart) were assessed at baseline and at each follow-up.
Results:
There was a statistically significant improvement (by paired t-test) in DBCVA (0.455 ± 0.266 vs. 0.093 ± 0.185;P < 0.001), contrast sensitivity (1.37 ± 0.34 vs. 1.54 ± 0.20;P < 0.001), and stereopsis (166.79 vs. 66.90;P < 0.001) from baseline at the end of 12 months. Improvement in DBCVA was statistically significant (P < 0.05 by analysis of variance test) in all types of amblyopia.
Conclusion:
Amblyopia therapy is effective in improving DBCVA, contrast sensitivity, and stereopsis in older children aged 9–18 years, which was maintained at the end of 12 months. |
