Abstract

Purpose : To describe findings in OCT Angiography and Fluorescein Angiography in patients with Adult Onset Viteliform Macular Distrophy (AVMD)

Methods : An observational, prospective study, which included 12 eyes of 6 patients with AVMD. The exam was performed on OCTA RTVue® XR Version 2015.1.0.90 with Cross Line (size: 10mm), Radial Lines (size: 8mm), Retina Map (6mm x 6 mm), 3D Widefield MCT (12mm x 9mm), AngioVue Retina (3mm x 3mm), Enhanced HD Line (12mm). The FA (Fluorescein Angiography) was done after excluding any contraindication of contrast injection, considering hypersensibility reaction or kidney failure.

Results : The commom findings in the vitelliform lesions was a low flow signal resulted from the block of the yellowish material, observed from the inner retina to choroid; in the Pseudo-hypopyon, a low flow signal of the lesions border; in the geographic atrophy a persistent high flow signal of choroid vessels observed from the inner retina layers to choroid; in the choroid neovascularization, a round shape vessels (lacy wheels).

Conclusions : In this study, we evaluate the importance, difficulties and practicality of OCT-A, mainly in the detection of CNV in the early stages, when the pattern of the AFG becomes difficult to analyze because of the small size of the lesion. Then it works like a complementary method to the tests considered the gold standard today for the retinal vascular disorders, and improvements in the software and algorithms may allow in the future, the end of contrast use to study the retinal vessels.

This is an abstract that was submitted for the 2017 ARVO Annual Meeting, held in Baltimore, MD, May 7-11, 2017.
