We reviewed the records of 61 patients with age-related macular degeneration who had an exudative or a dry macular scar and who had received low-vision rehabilitation. Exudative scars resulted from the natural course of sub-retinal new vessels, and dry scars from successful photocoagulation to the new vessels. Low-vision aids consisted of high-power positive lenses. Eyes were divided into three groups according to their distance visual acuity before using low-vision aids: Group 1, 20/100; Group 2, 20/200 to 20/300; and Group 3, 20/400 or poorer. The print size resolution on the Rosenbaum pocket vision screener and power of the low-vision aid in each group were compared for the eyes having exudative scars and those with dry photocoagulation scars. In Groups 2 and 3, eyes with dry macular scars reached a similar resolution of print size but with significantly (P less than .01) lower-power visual aids than eyes with exudative macular scars. In Group 1, eyes with dry macular scars achieved a better print size resolution using significantly (P less than .01) lower-power visual aids than eyes with exudative scars.
我们回顾了61例年龄相关性黄斑变性患者的记录，这些患者有渗出性或干性黄斑瘢痕，并接受了低视力康复治疗。渗出性瘢痕由视网膜下新生血管的自然病程导致，干性瘢痕则来自对新生血管成功进行光凝治疗后。低视力辅助器具包括高倍正透镜。根据使用低视力辅助器具前的远视力将眼睛分为三组：第1组，视力为20/100；第2组，视力为20/200至20/300；第3组，视力为20/400或更差。对有渗出性瘢痕的眼睛和有干性光凝瘢痕的眼睛，比较了罗森鲍姆袖珍视力筛查仪上的印刷字体分辨率和每组低视力辅助器具的度数。在第2组和第3组中，有干性黄斑瘢痕的眼睛达到了相似的印刷字体分辨率，但与有渗出性黄斑瘢痕的眼睛相比，使用的低视力辅助器具度数显著更低（P小于0.01）。在第1组中，有干性黄斑瘢痕的眼睛使用的低视力辅助器具度数显著更低（P小于0.01），却获得了更好的印刷字体分辨率。
