Sildenafil-induced bilateral ciliochoroidal effusion syndrome: Case report

To report a case of bilateral ciliochoroidal effusion syndrome associated with sildenafil use.

A 41-year-old male presented with a five-day history of bilateral blurred vision, elevated intraocular pressure, and myopic shift. Ultrasound biomicroscopy radial scans showed closed angles and 360 degrees of ciliochoroidal effusion in both eyes. Anterior segment coherence tomography angiography showed bilateral shallow anterior chamber. Further questioning revealed that the patient had taken sildenafil several times just a few days before symptoms appeared. Since then, the patient stopped dosing sildenafil. After treatment of anti-inflammation and shifting the lens-iris diaphragm posteriorly, the patient's visual acuity improved and intraocular pressure decreased. Follow-up ultrasound biomicroscopy and anterior segment coherence tomography angiography revealed resolution of ciliochoroidal effusion and increase of anterior chamber depth in both eyes.

The patient demonstrated a rare case of sildenafil-induced bilateral ciliochoroidal effusion syndrome. This case report shows that sildenafil should be added to the possible causative agents of ciliochoroidal effusion syndrome.
