Complications And Prognosis

Rarely, patients with chronic IK may develop progressive corneal opacification, which decreases visual acuity. Such patients may require corneal transplantation. Cataracts may also occur and require extraction. Serious posterior segment eye disease can lead to decreased visual acuity. The hearing decline is the major debilitating complication of CS. Progression to deafness is frequent and occurs in approximately 25% to 50% of patients. Many patients have benefited from a cochlear implant, which has dramatically improved their quality of life. Vestibular symptoms usually improve with time, but as many as 20% of patients may have persistent oscillopsia.
