OBJECTIVE

To calculate the percentage of blindness in the mass and evaluate the current conditions of treatment for cataract.

METHODS

In accordance with the national unified standards and procedures, a clue survey of the people aged under 40 years and a general survey of the people over 40 years in Gejiu city, Yunnan province were carried out. In the mean time, operations were performed for the patients with cataract.

RESULTS

Of the total 361 214 persons being surveyed, there were binocular blindness in 1 037 cases (0.29%) and monocular one in 983 cases (0.27%). Of the cases with binocular blindness, 593 cases (57.18%), and of the monocular blindness, 617 cases (62.77%) could be treated. The leading causes of 1037 cases with binocular blindness were cataract (51.98%), injuries of the eye (19.96%), corneal opacity (16.00%), glaucoma (10.03%), refractive error and other ocular diseases (2.03%). The average prevalence rate in the female cases was higher than that of male cases (chi(2) = 53.48, P < 0.01). Blindness was associated with older age There were variations in the prevalence rates in different aboriginals and in cases with different occupations. Cataract was the main disease to cause both the monocular and binocular blindness. Among the patients with cataract 539 cases (90.98%) of binocular blindness and 500 cases (81.03%) of monocular blindness were curable. The cataract operation was performed on 738 cases with cataract, including 396 cases with binocular blindness and 342 cases with monocular blindness. At postoperative 3 months, the rate of the best corrected visual acuity (eye sight > 0.05) was accounted for 97.73%, the rate of the eye sight > 0.3, 86.36% and the rate of wearing glasses (including implantation of intraocular lens), 85.60%.

CONCLUSION

The prevalence of blindness is associated with the aboriginal, occupation, age and the sex. The leading cause of blindness is cataract. So the surgical restoration of vision in cases with cataract is the main measure in the prevention of blindness.

目的

计算群体中的失明率并评估白内障的当前治疗状况。

方法

按照国家统一标准和程序，对云南省个旧市40岁以下人群进行线索调查，对40岁以上人群进行普查。同时，为白内障患者实施手术。

结果

在总共361214名受调查者中，双眼失明1037例（0.29%），单眼失明983例（0.27%）。在双眼失明病例中，593例（57.18%），单眼失明病例中，617例（62.77%）可以治疗。1037例双眼失明的主要原因是白内障（51.98%）、眼外伤（19.96%）、角膜混浊（16.00%）、青光眼（10.03%）、屈光不正及其他眼病（2.03%）。女性病例的平均患病率高于男性病例（χ² = 53.48，P < 0.01）。失明与年龄较大有关。不同民族和不同职业的患病率存在差异。白内障是导致单眼和双眼失明的主要疾病。在白内障患者中，双眼失明539例（90.98%），单眼失明500例（81.03%）可治愈。对738例白内障患者实施了白内障手术，其中双眼失明396例，单眼失明342例。术后3个月，最佳矫正视力（视力>0.05）率为97.73%，视力>0.3率为86.36%，配镜（包括人工晶状体植入）率为85.60%。
