Neovascular AMD is the most common cause of vision loss in people over the age of 65 . With the evolution of diagnostic imaging this portion of the population, at greatest risk of developing neovascular AMD, can be efficiently and effectively screened for MNV using OCT-A. Currently, dye angiography and SD OCT remain the gold standard for the diagnosis and follow up of MNV, and these techniques have guided the approach to treating neovascular AMD for years. This approach was in fact based on "reactive" therapeutic regimens [15, 16]. However, dye angiography is an invasive method requiring a long time to perform, also providing only two-dimensional imaging and is not free from a series of risks (albeit with a low incidence) such as nausea, allergy and, rarely, anaphylaxis. In addition, FA has a low sensitivity for type 1 MNV, since these lesions present a poorly defined area of leakage both in the early and late times of angiography [2–5]. On the other hand, the SD OCT has a limited ability to discriminate the MNV themselves; this method is able to recognize the indirect pathological signs of neovascularization, such as serous exudation, elevation of the RPE and retinal thinning. Furthermore, SD OCT has limited specificity, since it is not always able to differentiate active MNVs from normal choroidal vascularity, fibrotic scars, and accumulation of lipids or fibrous material under the RPE. Finally, it can be difficult to distinguish NE-MNV from drusenoid retinal pigment epithelial detachments resulting from the confluence of soft drusen, as both appear as collections of moderately reflective material in the sub-RPE space at SD-OCT [17–20]. Recent studies have shown that OCT-A can accurately identify microvascular structures and that it can be used to classify the morphology of type 1, type 2 and type 3 MNV . Using OCT-A the MNVs can be visualized with particular attention to the morphological details, thus allowing a qualitative and quantitative evaluation of the microvascular characteristics and a classification based on size, morphology, caliber of the vessels and the presence of retinal fluid . The appearance of MNV does not depend on its activity and vascular loss, therefore both exudative and non-exudative forms are diagnosable with OCT-A [17–20]. Precise localization and measurement in MNV with OCT-A can be an effective tool for monitoring NE-MNVs and may contribute to therapy planning. In fact, repeated scans of the lesion allow an effective measurement of the growth rate in a faster and safer way than angiography. In our study OCTA imaging revealed 18 non exudative type 1 MNV in 211 eyes with intermediate AMD. In eyes where subclinical MNV was detected, exudation developed in 9 patients. The neovascular lesions were classified as type 1 MNV and all the lesions presented elevation of the RPE associated with the MNV. Usually MNV was associated with a flat ped in b-scan imaging (Fig. 1), sometimes the RPE elevation was at the margin of an area of geographical atrophy (Fig. 2). In all eyes that showed exudation, we found a larger basal and final area of the lesion and a larger flow area. Both groups exhibited a similar growth rate, so the MNVs that developed exudation were probably in a more advanced stage. It is our interest to follow in the next months the patients who did not show exudation to understand if a further increase in area and flow coincides with an activation; this could be useful to understand if there is an area of the lesion beyond which the exudation is very likely. It is common practice in clinical practice not to treat asymptomatic MNV as they are not associated with intra or sub retinal fluid, as they do not possess the criteria for eligibility for treatment with anti VEGF . However, the widening of the surface of the lesion could represent a sign of progression to more aggressive forms of the disease. Laighinhas et al.20 found in the reviewed studies about 25% of NE-MNV lesions became exudative. Some authors have shown that enlargement of NE-MNV may be predictive of exudation, whereas others have not. In our study the area and the flow of nonexudative lesions seems to be an important predictive factor for exudative disease. However, OCT-A imaging has several limitations, such as poor fixation by the patient and projection artifacts. A limitation of this study is the number of patients, since non exudative MNV is an uncommon form of AMD.
