Visual function for ten patients undergoing HPD-PRT was tested using 1) the Graham Field Eye Chart for distance vision, 2) pseudo-isochromatic plates for color vision, and 3) Amsler grid for changes in macular function. Whereas some increases and decreases in ocular function were observed, no clear patterns or changes of significance were observed.
使用以下方法对10名接受血卟啉衍生物光动力疗法（HPD-PRT）的患者的视觉功能进行了测试：1）使用格雷厄姆视野视力表测试远视力，2）使用假同色图测试色觉，3）使用阿姆斯勒方格表测试黄斑功能变化。虽然观察到了一些眼功能的增加和减少，但未观察到明显的模式或显著变化。
