Anterior segment abnormalities and angle-closure glaucoma in a family with a mutation in the BEST1 gene and Best vitelliform macular dystrophy.

摘要

PURPOSE: To present the clinical and electrophysiological findings in four members of a family with Best vitelliform macular dystrophy (BVMD) and angle-closure glaucoma (ACG). METHODS: Four members of a family with BVMD were examined clinically, including visual acuity, slit-lamp examination, biomicroscopy, Goldmann applanation tonometry and gonioscopy. Measurements of the anterior chamber depth and axial length, visual field, optical coherence tomography, full-field electroretinography, multifocal electroretinography and electrooculography were performed. In addition molecular genetic analysis of the bestrophin-1 gene (BEST1), the microphthalmia-associated transcription factor gene (MITF) and the cone-rod homeobox gene (CRX) were performed. RESULTS: Four family members with the c.253T>C p.Y85H mutation in the BEST1 gene and BVMD in different stages also exhibited anterior segment abnormalities such as shallow anterior chambers (two cases), and reduced axial lengths in all cases.
