视力损害（包括盲）

定义

下表根据视力水平对视力损伤的严重程度进行了分类。 对于流行病学研究，建议收集每只眼睛在双眼睁开、远距离和近距离条件下的以下视力信息： a. ‌未矫正视力‌（9D96） b. ‌当前视力‌（9D94） c. ‌最佳矫正视力‌（9D95） 此外，盲症还根据较好眼的中央视野范围缩小至小于10度的程度进行分类。 ‌说明‌： 术语“uncorrected/presenting/best corrected visual acuity”采用眼科标准译法，分别对应“未矫正/当前/最佳矫正视力”。 “central visual field”译为“中央视野”，符合医学文献用语。 保留了原文的编号格式（如9D96）和术语缩写，便于对照原文。

!markdown The table below gives a classification of severity of vision impairment based on visual acuity. For epidemiological studies, it is recommended to collect the following information on visual acuity for each eye, for both eyes open and for distance and near. a. Uncorrected visual acuity (9D96) b. Presenting visual acuity (9D94) c. Best corrected visual acuity (9D95) Blindness is also categorized according to the degree of constriction of the central visual field in the better eye to less than 10 degrees. | Category | Visual acuity *1 <br> Worse than: | <br> Equal to or better than: | |----------|--------------------------------|---------------------------------------------| | No vision impairment | | 6/12<br>5/10 (0.5)<br>20/40<br>0.3 | | 1 Mild vision impairment | 6/12<br>5/10 (0.5)<br>20/40<br>0.3 | 6/18<br>3/10 (0.3)<br>20/70<br>0.5 | | 2 Moderate vision impairment | 6/18<br>3/10 (0.3)<br>20/70<br>0.5 | 6/60<br>1/10 (0.1)<br>20/200<br>1.0 | | 3 Severe vision impairment | 6/60<br>1/10 (0.1)<br>20/200<br>1.0 | 3/60<br>1/20 (0.05)<br>20/400<br>1.3 | | 4 Blindness | 3/60<br>1/20 (0.05)<br>20/400<br>1.3 | 1/60 or counts fingers (CF) at 1 metre<br>1/50 (0.02)<br>20/1200 or counts fingers (CF) at 1 metre<br>1.8 | | 5 Blindness | 1/60<br>1/50 (0.02)<br>5/300 (20/1200)<br>1.8 | Light perception | | 6 Blindness | No light perception | | | 9 | Undetermined or unspecified | | | Near vision impairment | N6 or M 0.8 at 40cms | | *1 Presented in metres, decimals, feet and logMar
