Macular optical coherence tomography (OCT) changes in anisometropic amblyopia before and after part time occlusion treatment
Keywords:
macular optical coherence tomography (OCT), anisometropic, amblyopia, BCVAAbstract
Background: Amblyopia denotes unilateral (or rarely bilateral) decrease of best corrected visual acuity (BCVA) with no identifiable organic pathology of the eye or visual pathway. It results from vision deprivation and/or abnormal binocular interaction. Aim and objectives: The aim of work was to measure the thickness of macula, nerve fiber layer, and ganglion cell layer by the use of optical coherence tomography (OCT) in eyes with anisometropic amblyopia before and after part-time occlusion therapy. Patients and methods: It was a prospective comparative clinical study conducted during the period from June 2020 through December 2020 and Mattaria teaching hospital. The total sample size is 50 eyes of 50 participants. Each treatment should have a confidence level of 95% and a margin error of 5%. Results: There was a statistically significant difference in the central macular thickness when compared before and after amblyopia treatment (the difference was more than 10 µm in 11 patients, while it was less than 10 µm in the rest of the patients), while the difference was statistically insignificant in either average macular thickness or total volume.
