Vision loss in a patient with primary pulmonary hypertension and long-term USE of sildenafil.
Abstract
PURPOSE: To describe a case of bilateral, asymmetrical outer macular atrophy in a patient with pulmonary hypertension treated with long-term sildenafil (Revatio).
METHODS: Case report with fundus photography, spectral domain optical coherence tomography, fundus autofluorescence, and fluorescein angiography imaging.
RESULTS: A 32-year-old African American woman with a history of primary pulmonary hypertension and 5-year history of oral sildenafil (Revatio) use presented with decreasing central vision in her left eye. She reported a decline in central vision in the left eye that started 1 month after treatment initiation and progressed until discontinuation 5 years later. Visual acuity was 20/20 in the right eye and 20/100 in the left eye. Fundus photography revealed retinal pigment epithelial mottling and atrophy in the right eye and parafoveal retinal pigment epithelial mottling and atrophy in a ring-like configuration of the left eye. Optical coherence tomography demonstrated outer retinal irregularity in the right eye and disrupted outer retina involving the external limiting membrane, inner segment/outer segment junction, and the retinal pigment epithelium in the left eye; no choroidal thickening was observed. Fundus autofluorescence showed mild hypoautofluorescence in the foveal center with an irregular autofluorescence pattern in the parafovea of the left eye. Fluorescein angiography revealed capillary dropout with pinpoint hyperfluorescence and leakage in the far…
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
