Purpose: To analyze the hyperacuity defects by preferential hyperacuity perimeter (PHP) in exudative age-related macular degeneration (AMD) and correlate them with the properties of pigment epithelial detachment (PED) obtained by optical coherence tomography (OCT).
Methods: Thirty eyes with exudative AMD with choroidal neovascularization (CNV) diagnosed by fluorescein angiography underwent PHP for hyperacuity defect and OCT for PED length and height. We compared hyperacuity defect with the shape of the PED by OCT.
Results: 26 eyes with exudative AMD with CNV tested positive for hyperacuity defects. The size of the hyperacuity defect by PHP and the PED length by OCT showed positive correlation (p=0.010). In the 4 eyes that tested negative for hyperacuity defects, the PED was not high although the size was large.
Conclusions: Our results suggest that PHP is a useful method to detect a change of pigment epithelial layer in AMD and the presences of a hyperacuity defect is more sensitive for PED height than size. These results suggest that PHP is useful to detect the state and the activity of CNV lesion
