Abstract
PurposeTo present a case of occult macular dystrophy accompanying normal-tension glaucoma. DesignObservational case report. MethodsVisual function and ophthalmoscopic and electroretinographic findings in a 56-year-old man suffering from gradually progressive photophobia and visual dysfunction were followed up over 4 years. ResultsBest-corrected visual acuity was below 20/200, and intraocular pressures remained in the low teens in both eyes. A wedge-shaped visual field defect in the right eye, corresponding to the enlarged disk cupping, and a relative central scotoma in the left were detected. Ophthalmoscopy and fluorescein angiography detected no apparent abnormality at the macular region in either eye. Severely attenuated multifocal electroretinographic responses were recorded from only the central areas, with normal full-field responses. ConclusionClinicians must look for additional pathologic conditions in patients with normal-tension glaucoma who have unexplained central visual dysfunction.
