Multifocal choroiditis and choroidal neovascularization associated with the multiple evanescent white dot and acute idiopathic blind spot enlargement syndrome.
BACKGROUND
Several recent articles have described syndromes in which there is enlargement of the blind spot associated with retinal lesions. These have included the multiple evanescent white dot syndrome, acute macular neuroretinopathy, acute idiopathic blind spot enlargement syndrome, and multifocal choroiditis or pseudo presumed ocular histoplasmosis syndrome (pseudo POHS).


METHODS
The authors reviewed the records of seven patients in whom signs and symptoms of acute enlargement of the blind spot and pseudo POHS developed.


RESULTS
All seven patients had photopsia accompanying enlargement of the blind spot during their illness. Four had transient white spots as seen in the multiple evanescent white dot syndrome. All presented with or developed chorioretinal scars or neovascularization similar to that seen in multifocal choroiditis or pseudo POHS. In four of the seven patients, POHS-like scars developed only in the eye that was symptomatic with blind spot enlargement and photopsia. Five of the 7 had visual acuity of 20/25 or better at the last follow-up.


CONCLUSIONS
It would appear that there is an overlap in the clinical findings of all of these syndromes and that there may be a common link in their etiology.
