Serous Neurosensory Retinal Detachment Associated With Atypical Cogan Syndrome: A Case Report

To present a case of a 71-year-old woman with possible focal choroiditis and secondary serous neurosensory retinal detachment associated with atypical Cogan syndrome.Retrospective case report.On initial evaluation, the patient had decreased vision with photopsias and distortion in the affected eye. Her history revealed 3 years of preexisting neurosensory hearing loss and corneal scarring in the affected eye. Examination findings were significant for unilateral interstitial keratitis and focal macular neurosensory retinal detachment. Fluorescein and indocyanine green angiography demonstrated focal macular leakage and staining. Treatment with intravitreal and periocular steroid injections resulted in complete resolution of the subretinal fluid and visual improvement.Posterior segment manifestations associated with Cogan syndrome are exceedingly rare. This is the first known case of a serous neurosensory retinal detachment from suspected choroidal inflammation associated with Cogan syndrome. Prompt recognition and treatment with corticosteroids may result in anatomical and functional visual improvement, as in this case.
