This patient is receiving ongoing intravitreal Avastin injections for a type 1 macular neovascularization (MNV) from wet AMD.
The injections caused the MNV to involute and contract, dragging the overlying RPE into radiating radial folds. This is best seen in the cool OCT en face view. The RPE folds are also seen in the OCT retinal map and OCT B-scan.
Learning Points:
Macular neovascularization is known by many other terms, including choroidal neovascular membrane, subretinal neovascular membrane, etc.
However, since these vessels are now known not to necessarily arise just from the choroid, the proper term is macular neovascularization (see Consensus on Neovascular Age-Related Macular Degeneration Nomenclature Study Group Ophthalmology 2020;127;616-636).
MNV is classified according the location of the new vessels in relation to its location relative to the RPE and neurosensory retina: type 1 (below the RPE), type 2 (between the RPE and neurosensory retina, and type 3 (within the neurosensory retina).
