Central serous chorioretinopathy after trabeculectomy in a patient with microphthalmos and congenital rubella syndrome.

Purpose: To describe a case of central serous chorioretinopathy after trabeculectomy surgery in an eye with microphthalmos in the setting of congenital rubella syndrome.
Methods: A Case report with color fundus photographs, fluorescein angiography, and spectral domain optical coherence tomography.
Results: A 46-year-old African American man, with a history of congenital heart disease and bilateral hearing loss, developed persistent vision loss in the left eye after trabeculectomy surgery. Ocular examination revealed bilateral salt-and-pepper retinopathy and a serous detachment in the macula of the left eye. Fluorescein angiography showed an early "smoke-stack" pattern of hyperfluorescence with progressive filling of the subretinal space consistent with central serous chorioretinopathy. Spectral domain optical coherence tomography documented both size and extent of the serous retinal detachment and showed several pigment epithelial detachments. B-scan ultrasonography confirmed the serous retinal detachment on the left but showed no evidence of posterior eye wall thickening or of retrobulbar fluid. An A-scan revealed an axial length of 21.8 mm on the right and 19.7 mm on left eye, confirming microphthalmos and supporting the suspected diagnosis of congenital rubella syndrome.
Conclusion: Although uncommon, central serous chorioretinopathy can occur in anatomically small eyes after trabeculectomy surgery.
