The clinical course of serpiginous choroidopathy

We closely observed nine patients (17 eyes) with serpiginous choroidopathy for time periods ranging from two to ten years. There were seven men and two women with ages ranging from 22 to 58 years, average age was 46 years. Eight patients were bilaterally affected; one patient had only one eye. The clinical course of the disease was characterized by multiple recurrences. The recurrences and progression of the disease often were not noticed by patients if the macular area was not involved. Serial fundus photographs proved to be invaluable in establishing progression. Although the disease usually progresses in a centrifugal manner from the disk toward the periphery, three patients demonstrated centripetal progression and one of these three permanently lost central acuity. Visual acuity was affected only when the foveal or parafoveal areas became involved, but in nine of the 17 eyes, visual acuity returned to a variable degree. None of the patients had any general systemic illness. However, five of the patients reported chronic exposure to an unusual variety of chemicals.
