Not All That Flickers Is Snow

J Neuroophthalmol. 2021 Mar 1;41(1):e97-e99. doi: 10.1097/WNO.0000000000000935.


A woman presented with bilateral visual disturbances that had been diagnosed as visual snow. Dilated ophthalmic examination and multimodal imaging were strongly suggestive of birdshot chorioretinopathy, meriting initiation of systemic immunomodulatory therapy. Visual snow requires a thorough ophthalmologic exam to exclude other ocular diseases.
