of the eye, including: Cataract Conjunctivitis Corneal injury such as corneal ulcer or corneal swelling Diabetic retinopathy Fuchs' dystrophy Keratoconus (Fleischer ring) Macular degeneration Retinal detachment Retinal vessel occlusion Retinitis pigmentosa Sjögren's syndrome Toxoplasmosis Uveitis Wilson's disease (Kayser-Fleischer ring) One sign that may be seen in slit lamp examination is a "flare", which is when the slit-lamp beam is seen in the anterior chamber. This occurs when there is breakdown of the blood-aqueous barrier with resultant exudation of protein.
