[A case of atypical serpiginous choroiditis with chorioretinal lesions along retinal blood vessels]

Serpiginous choroiditis, a chronic disease affecting the choroid and retinal pigment epithelium, is characterized by acute lesions located adjacent to atrophic scars initiated from the peripapillary region. This report describes a chorioretinal disease accompanied with retinal phlebitis finally diagnosed as serpiginous choroiditis by the characteristic extension of the lesions.

A 68-year-old man was referred to our hospital with blurred vision in his both eyes. A small amount of cells infiltrating the vitreous, partial vitreous opacity, retinal phlebitis, grayish-white lesions around the optic disc and retinal phlebitis, and cystoid macular edema were observed in the both eyes. Since active lesions were found at the border of the inactive lesions and appeared in an interlocking polygonal pattern that spread out continuously, the condition was diagnosed as serpiginous choroiditis with retinal phlebitis. Systemic administration of predonisolone was initiated, which resolved the retinal phlebitis, and the active lesions were turned to scars. No recurrence has been observed since.

Atypical serpiginous choroiditis accompanied with retinal phlebitis responds to systemic steroid administration.
