Abstract
Aim: To compare macular and peripapillary RNFL thickness in amblyopic & fellow eye in unilateral amblyopia,using OPKOS SLO/OCT.
Method: A prospective cross sectional study was conducted on 55 patients (37 anisometropia,10 strabismic & 7 form deprivation) of 5-40y of age(mean 20.2±8.4).Macular and RNFL thickness were measured using SD-OCT(OPKOS SLO/OCT) and compared.
Result: Mean macular thickness of all amblyopia patients showed statistically significant increase (P=0.05) in amblyopic eye( AE=262.27±19.29,Non AE=255.21±18.63).On subgroup analysis, increase was significant only in anisometropes (P=0.03)while RNFL thickness was increased in strabismic amblyopes (P=0.04).(AE=102.22±14.06 Non AE=93.55±12.24).No correlation was found with age of patient.
Conclusion: There was a significant increase in mean macular thickness in 55 amblyopes,which was significant only in anisometropes, while RNFL thickness was significantly increased only in strabismic amblyopia, when compared with fellow eye. These results corroborate with findings of similar previous studies.
