Central Serous Chorioretinopathy Development following Cessation of Terbinafine Treatment

This report describes a case of central serous chorioretinopathy (CSCR) occurring following cessation of terbinafine treatment. A 51-year-old man presented for a routine ophthalmic examination. He was treated with oral terbinafine for onychomycosis up to 3 months before the presentation. Spectral-domain optical coherence tomography (OCT) showed extrafoveal subretinal fluid in both eyes with small underlying pigment epithelial detachments. There were no additional relevant findings in the patient history or ocular examination. A diagnosis of CSCR was made. After 10 weeks without treatment, OCT demonstrated almost complete resolution of subretinal fluid in both eyes. The exact key ingredients of the perfect storm leading to CSCR in young, healthy individuals are still unknown. Here, we describe, to our knowledge, the first documented case, where the appearance of CSCR was apparently triggered by cessation of antifungal treatment. This unusual case may provoke further research that will bring us closer to understanding the mechanism behind the appearance of CSCR. It may also widen the scope of the routine anamnesis when dealing with patients newly diagnosed with this enigmatic condition.
