FOCAL SCLERAL NODULE

Originally posted on @retina.rocks 10/28/2021

This patient presented with an asymptomatic yellowish, nodular subretinal lesion inferonasal to the right optic nerve.

Spectral domain optical coherence tomography shows that the lesion originates from the sclera. 

Learning Points:
Focal scleral nodule (previously known as solitary idiopathic choroiditis [SIC] and unifocal helioid choroiditis) presents as a single, yellow-white, elevated nodular, avascular subretinal lesion. On OCT, it arises from the inner sclera, causing marked choroidal compression.

For the largest series to date and the rationale behind the renaming of this entity, see Fung et al, Ophthalmology 2020;127:1567-1577.
