This 65YO female is receiving ongoing anti-VEGF therapy in her right eye for macular neovascularization (MNV).
Optos imaging shows an inactive pigmented MNV OD and bilateral peripapillary degenerative propeller-shaped lesions radiating from the optic nerves.
Vision is 20/40 OD and 20/30 OS.
Learning Points:
Helicoid peripapillary chorioretinal degeneration (HPCD) is a benign autosomal dominant disorder caused by a mutation in the TEAD1 gene.
It is characterized by a unique pattern of bilateral peripapillary chorioretinal atrophy. These degenerative wing or propeller-shaped lesions radiate centrifugally from the optic nerve head.
Vision is usually normal, although central vision can rarely be affected if atrophy progresses through the fovea. MNV can rarely develop as in our patient (see Triantafylla et al, Eur J Ophthalmol 2016;26:e30-e31).
