中文摘要 | 背景: 探討長庚醫院低視能病人的特性,及各種低視能輔具的臨床價值。 方法: 我們收集自西元1998至2001年期間,共203位低視能初診病人的資料,評估其使用低視能輔具的成功率。並分別與1984至1987年及1991至1994年兩個不同時期的報告比較,分析他們在年齡、性別、視力及造成低視能病因的異同。 結果: 經過謹慎的驗光之後,有21位(10.3%)配戴一般眼鏡即可滿足看遠及看近視力的需求;其中3位偏盲患者,可接受高偏折稜鏡。在121位有看遠需求者中,84位(69.4%)可成功使用望遠鏡,如加用頭戴式輔助,則僅多1位成功者。在136位無法閱讀報紙者中,有118位(86.8%)可成功使用放大鏡,再加用擴視機,則可達125位(91.9%)。與過去的資料比較,目前低視能病人的平均年齡有逐漸增高的趨勢,其病因也有相對變化的現象。 結論: 擴視機可以幫助某些無法使用光學放大鏡滿足看近需求的病人。然而目前我們的多數患者仍以使用傳統光學輔具為主。 |
英文摘要 | Background: The aims of this study were to determine the clinical effectiveness of optical and video low vision aids (LVA) and analyze the characteristics of the visually impaired at the low vision clinic of Chang Gung Memorial hospital. Methods: The use of LVA to improve distance and near visual functions was evaluated in 203 new patients from 1998 through 2001 at our clinic. The age, gender, visual status, and primary condition causing low vision of the patients were also compared with data obtained from two different study periods. from 1984 through 1987 and 1991 through 1994. Results: After careful refraction, spectacles only were able to meet both distance and near visual requirements in 21 patients (10.3%), and among them, 3 patients with hemianopsia were further prescribed Fresnel prisms. Of the 121 patient with distance visual requirements, 84 (69.4%) benefited from using telescopes; however, only one additional patient benefited from the addition of a head-mounted device. Of the 136 patients who could not read the newsprint, 118 (86.8%) succeeded in reading newsprint using optical magnifiers, and up to 125(91.9%) with using the addition of a closed circuit television. Compared with the previous data, the average age of our patients has steadily increased, and the main cause of ocular pathology has changed accordingly. Conclusion: Video magnifiers provided suitable rehabilitation for some patients who failed to see clearly using optical magnifiers. However, most of our low vision patients, who have changed during the last decades, can accomplish their desired visual tasks using traditional LVA. |
