A new OCT finding in tuberculous serpiginous-like choroidopathy.

PURPOSE To present a case of tubercular serpiginous-like choroiditis (SLC) with previously unreported choroidal findings on enhanced depth imaging OCT (EDI-OCT). DESIGN Case report. METHODS A 60-year-old female presented with decreased vision. Serpiginous choroidopathy was diagnosed. Laboratory workup revealed an infectious etiology. EDI-OCT revealed previously unreported choroidal findings. RESULTS Laboratory workup revealed nonreactive Treponema pallidum antibodies and positive QuantiFERON Gold. CT chest showed scars of prior granulomatous disease. OCT with EDI of active lesions demonstrated infiltration of the choroid, elevation of the RPE-Bruch's membrane complex and focal increase of choroidal thickness. CONCLUSIONS Choroidal infiltration with elevation of the RPE was demonstrated on EDI-OCT in active areas of tuberculous serpiginous-like choroiditis in this patient. This finding has not been described in imaging of patients with noninfectious serpiginous choroidopathy and may be a useful tool to differentiate serpiginous choroidopathy (SC) from serpiginous-like choroiditis (SLC). EDI-OCT may provide characterization of choroidal involvement.
