Abstract Purpose:To report findings by optical coherence tomographic angiography(OCTA)in treated eyes of age-related macuar degeneration(AMD)with or without recurrence.

Cases and Method:This study was made on 29 eyes of 29 cases of AMD who were treated by intravitreal injection of anti-VEGF preparations. The series comprised 25 males and 4 females. Typical AMD was present in 22 eyes, polypoidal choroidal vasculopathy in 6 eyes, and retinal angiomatous proliferation in one eye. They were followed up for 6 months using OCTA. The findings and rate of recurrence were evaluated regarding parameters for the shape of CNV, branching, anastomosis and loop formation, shape of terminal vessels, and halo around the lesion.

Findings:AMD recurred in 10 out of 29 eyes within 6 months of treatment. Four out of these 10 eyes showed more than 3 points of parameters. None of the 19 eyes that showed no recurrence was scored 3 points or more. The score was thus significantly correlated with the recurrence(p=0.009). Branching of CNV, anastomosis or looping, morphology of the terminal vessels, decreased halo around the lesion were significantly correlated with recurrence of AMD(p<0.05).

Conclusion:OCTA showed characteristic findings of recurrence of AMD within 6 months of treatment.
