Abstract |
PURPOSE To analyze the hyperacuity defects of preferential hyperacuity perimeter (PHP) in myopic CNV and correlate with the other macular anatomical or physiological properties obtained with fluorescein angiography (FA), Optical coherence Tomography (OCT), and central perimeter. METHODS: Seven patients with myopic CNV diagnosed by FA underwent PHP, OCT, central visual field (VF). We examined the locational correlation among FA, central VF and PHP hyperacuity defect and then compared PHP hyperacuity defect with the CNV size by OCT. Also we made a comparison with macular sensitivity change in VF and hyperacuity defects change in PHP after PDT in 4 patients. RESULTS: All the 7 eyes with myopic CNV tested positive for hyperacuity defects. 5 eyes showed locational correlation among PHP and FA, central VF. The size of hyperacuity defect of PHP and CNV size by OCT was positive correlation (p=0.007). Four eyes treated with PDT showed decrease of PHP hyperacuity defect size and changes in location according to decrease of CNV size after PDT. CONCLUSIONS: Our results suggest that the PHP may be used to detect myopic CNV and beneficial for analyzing functional effect following PDT in myopic CNV patients. These results require further validation in a larger population. |
