Purpose: To report a case of Cogan syndrome that presented with the appearance of bilateral asymmetric corneal ectasia on Scheimpflug tomography. Methods: Case Report and Literature Review. Results: A 43-year-old woman previously diagnosed with keratoconjunctivitis sicca and presumed keratoconus presented with seven months of episodic eye pain and progressive bilateral blurry vision with new onset bilateral monocular diplopia. Review of symptoms were significant for tinnitus, vertigo, and sensorineural hearing loss that began many months after her initial presentation for visual symptoms. Scheimpflug tomography showed asymmetric focal steepening on anterior curvature with corresponding focal total corneal thinning, focal posterior elevation, and abnormal ARTMax (205 OD, 103 OS) and BAD-D (2.75 OD, 5.6 OS) values. Clinical examination was notable only for faint anterior corneal stromal inflammation without neovascularization, but there was significant corresponding focal hyperreflectivity on anterior segment optical coherence tomography (OCT) examination with focal epithelial hypertrophy rather than thinning. Given the combined findings of interstitial keratitis and sensorineural hearing loss the patient was diagnosed with Cogan syndrome. She responded well to topical steroids and systemic immunosuppressive therapy, with near resolution of her abnormal topographic and tomographic findings and resolution of monocular diplopia in both eyes. Conclusions: Cogan syndrome should be suspected for any patient with corneal stromal findings and associated with vertigo and/or hearing loss. Anterior segment optical coherence tomography (OCT) can distinguish between ectatic and inflammatory diseases and may help make the appropriate diagnosis in subtle cases. |
