ABSTRACT
PURPOSE: To report the longitudinal outcomes for AZOOR patients including treatment response, imaging evolution, and overlap with multiple evanescent white dot syndrome (MEWDS). METHODS: Visual acuity (VA) and visual field (VF) outcomes of occult and overt AZOOR patients were retrospectively compared between the first and final visits as well as between the two AZOOR subtypes. For treated patients, rates of VA change and fundus lesion area were compared before and after treatment. Analyses were performed using STATA 17. RESULTS: Seventeen eyes from 11 occult AZOOR patients and 45 eyes from 29 overt AZOOR patients were included. In a composite VA/VF primary outcome, clinical improvement was noted in five occult AZOOR and three overt AZOOR patients. The decline of logarithm of the Minimal Angle of Resolution (logMAR) VA was minimal in both groups: 0.00016 units/month in occult AZOOR patients and 0.009 units/month in overt AZOOR patients (p = 0.94). Occult AZOOR patients were more likely to have improved or stable VF than overt AZOOR patients (p = 0.04). One occult AZOOR and two overt AZOOR patients developed MEWDS at subsequent visits. Treatment with steroids or immunomodulatory therapy (IMT) was initiated in one occult AZOOR patient and nine overt AZOOR patients. Treated patients had overall VA stability. Fundus lesion area in treated patients changed by a mean of 0.2831 mm2/month, with 40% of patients showing decreased lesion area. CONCLUSION: AZOOR patients generally maintained their VA. Overt AZOOR patients were more likely to receive steroids or IMT; treatment was associated with stabilization of VA.
ABSTRACT
Purpose: To compare the efficacy of optical coherence tomography angiography (OCTA) and indocyanine green angiography (ICGA) for detecting nonexudative macular neovascularization (MNV) in age-related macular degeneration (AMD). Methods: In this prospective study, patients with a new diagnosis of exudative AMD in 1 eye were imaged using OCTA, fluorescein angiography (FA), and ICGA in both eyes. The rates at which these imaging modalities detected nonexudative MNV in the nonexudative fellow eye were then compared. Results: This study comprised 41 eyes with a mean follow-up was 14 months. Nonexudative MNV was found in 3 eyes using OCTA and ICGA. No MNV exudation was detected on FA or structural OCT. One of 3 eyes with MNV progressed to exudative disease 6 months after the initial visit. During the follow-up, 5 of the 38 eyes without MNV developed exudation at 4 to 18 months. Conclusions: OCTA is similarly effective as ICGA at detecting nonexudative MNV patterns.
