The objective of this study on patients with albinism in different age groups was to compare their level of visual impairment with the low-vision intervention (LVI) and its benefit.
The medical records of 72 patients with low vision secondary to albinism who were referred to the low vision care clinic from 2015 to 2017 were analyzed. This included the demographic profile such as age, gender, occupation, ocular history, visual acuity status, and type of low-vision device (LVD) preferred. The LVDs prescribed and its subsequent improvement was compared.
In this data, 70 (97.2%) people had oculocutaneous albinism and 2 (2.8%) had ocular albinism. Majority of the patients had hyperopic astigmatism 42 (58.3%) and with-the-rule astigmatism 58 (93.5%). Presenting mean visual acuity for distance was noted to be 0.88 logMAR which improved to 0.83 logMAR with the help of spectacle correction. The most commonly prescribed LVD was a dome magnifier for 15 (34.9%) patients. In all the patients, there was statistically significant improvement ( < 0.05) in near vision with the help of LVDs.
The study highlights the importance of appropriate LVI for each subdivided age group. Patients with albinism who have received medical and surgical treatment have no or a limited role in restoring useful vision.
本研究针对不同年龄组的白化病患者，旨在比较他们的视力损害水平、低视力干预措施及其效果。
分析了2015年至2017年转诊至低视力保健诊所的72例白化病继发低视力患者的病历。这包括人口统计学资料，如年龄、性别、职业、眼部病史、视力状况以及偏好的低视力辅助器具类型。比较所开具的低视力辅助器具及其后续改善情况。
在这些数据中，70例（97.2%）患有眼皮肤白化病，2例（2.8%）患有眼部白化病。大多数患者有远视散光42例（58.3%）和顺规散光58例（93.5%）。远距离的初始平均视力为0.88 logMAR，经眼镜矫正后提高到0.83 logMAR。最常开具的低视力辅助器具是圆顶放大镜，用于15例（34.9%）患者。在所有患者中，借助低视力辅助器具，近视力有统计学显著改善（<0.05）。
该研究强调了针对每个细分年龄组进行适当低视力干预的重要性。接受过药物和手术治疗的白化病患者在恢复有用视力方面作用不大或作用有限。
