Case report of brown mclean syndrome

Purpose: To report two rare cases of Brown McLean syndrome after cataract surgery in a patient with aphakia. Case summary: (Case 1) A 54-year-old woman with Marfan's syndrome who had aphakia and peripheral corneal edema after left eye cataract surgery 4 years ago. The patient had an elevated lesion in the peripheral cornea without involving the central cornea, and had symptoms of pain, irritation and tearing. Specular microscopy showed normal endothelial cell density and morphology in the edematous cornea. The peripheral corneal edema improved after use of antibiotics, autoserum eyedrops and 5% NaCl eyedrops. (Case 2) A 61-year-old woman with aphakia in her left eye after bilateral cataract surgery 11 years ago, underwent surgery for a macular hole in both eyes. The patient developed peripheral corneal erosions and edema in the left eye 2 months after the surgery. Specular microscopy showed normal endothelial cell density and morphology. The peripheral corneal edema was static over the years while using 5% NaCl eyedrops and artificial tears, and did not progress to involve the central cornea. Conclusions: Brown McLean syndrome is a rare disease but the possibility should be considered if a patient with aphakia after cataract surgery has peripheral corneal edema for several years.
