Abstract
PURPOSE
Preferential hyperacuity perimeter (PHP) is a device that measures metamorphopsia in the central 14 degrees of the macular visual field which is presented by hyperacuity defect. We elucidated a hyperacuity defect lesion of PHP in exudative age-related macular degeneration (AMD) by Optical coherence tomography (OCT). METHODS: Nineteen eyes of 18 patients with exudative AMD diagnosed by fundus examination and fluorescein angiography (FA) underwent PHP. We then elucidated any hyperacuity defect lesion of PHP by fundus photography, FA and OCT. For a control, 20 eyes of 10 age-matched persons who had no ophthalmological abnormality underwent PHP and OCT to determine if hyperacuity defect would appear. RESULTS: Hyperacuity defect lesion appeared in 18 eyes (95%) of AMD patients. There was good locational correlation between the hyperacuity defect lesions and lesions in the fudoscopic examination in 16 eyes of 18, but there was a counterpart relation at the superior-inferior and left-right in 2 eyes. Hyperacuity defect lesion in PHP was of smooth or irregular elevation of the retinal pigment epithelium (RPE) in OCT. In the control, hyperacuity defect lesion appeared in 1 eye (5%) and it was normal in OCT. CONCLUSIONS: PHP showed a highly positive rate in detecting AMD-related lesion. The hyperacuity defects that are noted by the PHP are produced from elevation of the RPE.
