Abstract

PURPOSE
This study was designed to evaluate the change of contrast sensitivity under the photopic and mesopic illumination in amblyopic patient after occlusion therapy. METHODS: The subjects comprised 32 pediatric patients with strabismic or anisometropic amblyopia who were followed up at the clinic. We measured the best corrected visual acuity and contrast sensitivity under the photopic and mesopic illumination using ACV instrument before and three months after occlusion therapy.
RESULTS
Mean best corrected visual acuity of amblyopic eyes before occlusion therapy was 0.54 +/- 0.21. In 17 eyes with improvement in best corrected visual acuity (mean: 0.21 +/- 0.05), there was improvement in photopic and mesopic contrast sensitivity (p<0.05). In 15 eyes without improvement in the best corrected visual acuity, there was no difference in photopic and mesopic contrast sensitivity (p>0.05).
CONCLUSIONS
From above mentioned results, we can conclude that the contrast sensitivity using ACV instrument is responsive to short term (three months) occlusion therapy for amblyopic eyes.
