Intraretinal microvascular abnormalities (or IrMAs) are shunt vessels and appear as abnormal branching or dilation of existing blood vessels (capillaries) within the retina that act to supply …

Nov 4, 2015 · Usually the IRMA is within the retina and does not occur on the disk. Neovascularization is on top or even growing into the vitreous and are associated with leaks …

Intraretinal microvascular abnormalities (IRMA) are abnormalities of the blood vessels that supply the retina of the eye, a sign of diabetic retinopathy. [1] IRMA can be difficult to distinguish from …

Optical coherence tomography angiography, through flow overlay, has utility to image and differentiate IRMA and NV, which are key features distinguishing severe non-PDR and PDR, …

Can be difficult to differentiate IRMA and NV! IRMA • Location: intraretinal (not at disc) • Appearance: Outline may be angulated with sharp corners. Do not cross over major retinal …

Jan 1, 2015 · In this study, we identified several OCT-derived parameters that distinguish IRMAs and NVEs. We suggest that current clinical and FA definitions of IRMA vs NVE should be …

IRMA and NV can be differentiated based on the size, shape location, color , configuration and FFA features. the video explains all those with examples. #Neovascularisation …

Mar 7, 2024 · Intraretinal microvascular abnormalities (IRMAs) refer to a potential complication of diabetic retinopathy. Damage may start to occur in the blood vessels of the eyes if a person …

Oct 1, 2019 · Neovascularization differed from IRMA on OCTA by demonstrating supraretinal flow breaching the internal limiting membrane and posterior hyaloid (P < 0.001).

The use of OCTA technology may provide a more noninvasive, efficient, risk-free way to identify IRMA and retinal neovascularization than FA, with the potential for use in screening and …
