A 36-YEAR-OLD man had sudden and painless reductionof central visualacuity, a subjective spherical equivalent increase (hyperopization), and metamorphopsias. Slitlamp biomicroscopy of the anterior segment was unremarkable. Intraocular pressure was in the normal range. Red-free ophthalmoscopy showed a circumscribed detachment of the fovea but no other details (Figure 1). Fluorescein angiography demonstrated a typical dye leakage from the choroid into the subretinal space in an umbrella-like or smokestack-like fashion (Figure 2 and Figure 3). At the base of the smokestack, pooling of fluorescein suggested a localizeddetachment of the retinal pigment epithelium. The circumscribed detachment of the retinal pigment epithelium was confirmed by opticalcoherence tomography and thus led to the diagnosis of central serous chorioretinopathy with associated detachment of the retinal pigment epithelium (Figure 4).1-3
