Correlation Between Morphological Features on Ultra-widefield Fluorescein Angiography and Optical Coherence Tomography Results in Patients with Idiopathic Epiretinal Membranes by Seungwoo Lee, South Korea

Seungwoo Lee, South Korea

Purpose:
To determine the association between ultra-widefield fluorescein angiography (UWFA) findings and spectral domain optical coherence tomography (SD-OCT) images in the idiopathic epiretinal membrane(ERM).

Methods:
A retrospective review of 92 eyes from 67 patients diagnosed with idiopathic ERM were analyzed. Peripheral vascular morphology was classified two groups (loop pattern and branching pattern) Microvascular abnormalities such as capillary telangiectasia, microaneurysm, or vascular leakage were evaluated. The appearance of ERM on SD-OCT was also classified into four types: lamellar hole with ERM, flat, convex and concave thickening of the foveal center. Statistical analysis was done to analyze the correlation in the peripheral vascular finding of UWFA by the morphological OCT pattern.

Results:
One or more peripheral anomalies were noted in all patients. The peripheral vascular morphology of UWFA patterns was statistically different according to SD-OCT images. Peripheral vascular loop pattern (64.7%) and vascular leakage(52.9%) were found to be more commonly seen in patients in convex foveal contour group on SD-OCT.

Conclusion:
The convex contour type in patients with ERM has a significantly higher incidence of microvascular abnormalities and the relationship with peripheral vascular morphology. These finding of this study may provide that peripheral vascular change involved in idiopathic ERM formation.
