[2] Serpiginous choroiditis is characterized acutely by irregular, gray-white or cream-yellow subretinal infiltrates at the level of the choriocapillaries and the RPE.

[1] Patients present with unilateral or bilateral visual loss when the macula is involved and they may also notice photopsias and scotomatas.

Persistent placoid maculopathy is a resistant form of serpiginous choroidopathy and resembles macular GHPC, but differs in its clinical course and effect on visual acuity as a majority of the eyes develop CNVM, resulting in central vision loss.

Immunosuppressive agents can help lengthen periods of disease inactivity and reduce the risk of potential side effects associated with high-dose steroids.
