Purpose: The preferential hyperacuity perimeter (PHP) is a new macular perimeter for monitoring AMD patients for development of CNV that displays the metamorphopsia. A dot deviation signals is flashed to the central 14° of macular visual field, and perceived hyperacuity defect is detected. The aim of this study was to determine that the PHP would have any useful role in the investigation of visual function in patients with maculopathy due to various retinal diseases besides AMD. Methods: Seventy four eyes (55 patients) with macular abnormality caused by various retinal diseases (44 eyes of diabetic retinopathy, 6 eyes of central serous chorioretinopathy, 24 eyes of other retinal diseases) underwent PHP, Optical coherence tomography (OCT) and fluorescein angiography (FA). The hyperacuity defects were correlated with OCT and FA. Results: Of 74 eyes with maculopathy, 60 eyes (81%) had a positive test for hyperacuity defects. Forty eyes (40/44, 91%) with diabetic retinopathy, 3 eyes (3/6, 50%) with central serous chorioretinpathy, and 17 eyes (17/24, 71%) with other retinal diseases showed positive PHP finding. The hyperacuity defect in the PHP appeared when a lesion is located in outer retinal layer as well as in retinal pigment epithelium. Regional correlation of location with OCT and FA were observed in 6 eyes (6/40, 15%) with diabetic retinopathy, 1 eye (1/3, 33%) with central serous chorioretinpathy, and 5 eyes (5/17, 29%) with other retinal diseases. Conclusions: The hyperacuity defect in PHP appeared in large number of maculopathy due to various retinal diseases. But regional correlation of location with other examination was not sufficient as in patients with AMD. The patient’s visual acuity and visual field defect should be considered when the PHP results are analyzed.
