[Prediction of curative effect of amblyopia by laser interference fringe visual acuity]

Laser interference fringe visual acuities (IVAs) and E visual acuities (EVAs) of 116 cases 171 amblyopic eyes were examined. All cases were treated by various therapies and the average follow-up was 2.5 years. Before treatment, the IVAs of 86.5% eyes were better than their EVAs and the IVAs of 13.5% eyes were equal to their EVAs. After treatment, the EVAs of all the eyes were raised to their IVA levels (P < 0.0001, r = 0.8218). The results show that the IVA examination can predict the curative effect and monitor the treatment of amblyopia. The relationships between the IVA and the character of visual fixation, the type and degree of amblyopia, elder child and adult amblyopia, etc. were discussed.
