Optical coherence tomography (OCT) OCT is useful in the initial stage of RAP to image the vessels and the cystic spaces within the retina. As the disease progresses and a serous or vascularized PED occurs, changes beneath the pigment epithelium become difficult …

SS-OCT is helpful in the diagnosis of RAP lesions; OCTA is an effective aid in monitoring flow reduction following anti-VEGF therapy in RAP lesions; and En Face is excellent for monitoring intra-retinal cyst reduction, among other things.

Through analysis of OCT findings, we revealed six different types of lesions distinctive of RAP which may provide helpful diagnostic information for subsequent treatment and predicting the prognosis of RAP.

OCT is a useful tool in the differential diagnosis between RAP, PCV and occult CNV (28,29). In RAP, intraretinal hyperreflectivity may be observed, corresponding to angiomatous proliferation associated with intraretinal fluid and/or RPE detachment (30,31).

Oct 29, 2010 · We propose a classification system for RAP on the basis of ICG and present the angiographic and OCT findings of these lesions. These data may further aid in the early diagnosis of RAP and can...

In this article, we describe the multimodal imaging features of precursor RAP lesions, including optical coherence tomography angiography (OCTA), and present the results of long-term follow-up with B-scan spectral domain optical coherence tomography (SD-OCT) using high sampling density and eye-tracking mode.

May 24, 2016 · Retinal angiomatous proliferation (RAP) is a unique variant of neovascular age-related macular degeneration. Published studies have estimated that up to 15% of patients with neovascular age-related macular degeneration have RAP.

RAP has distinct OCT features such as intraretinal cyst-like fluid accumulation 28–30, a break of the RPED 28,30, gently-sloping dome-shaped or trapezoid-shaped RPEDs without obvious peaks 13, intraretinal or intraretinal-subretinal hyperreflective mass lesions 28,31, and a …

The diagnosis of RAP stage 1 could be made both in the OCT, the FA and the OCT-A. All patients showed macular edema in the OCT. The FA showed selective hyperfluorescence in the early phase and fluorescein extravasation in the late phase.

The use of OCT‑A is helpful for the diagnosis and follow-up examinations of RAP lesions (type 3 neovascularization). It enables the detailed visualization of intraretinal and choroidal microcirculation.
