[Impact factor of timeliness lag for seeing a doctor about cataract patient in Wenzhou region of Zhejiang province].

OBJECTIVE: Investigation the impact factor of timeliness lag about cataract patient of operation. METHODS: Through Opportunistic Screening , from January 2007 to January 2012, we extracted people aged 50 or above and carried out the cataract screening in 10 towns of Wenzhou region of Zhejiang province. People extracted was checked by slit lamp microscope and ophthalmoscope directly, and the people who are suit for operation were brought to a first-rate of level three eye hospital and operated by MSICS . At the same time we have made questionnaire about five aspect including basic situation, economic status, basic life status, health and medical status and health needs for the operator and this questionnaire involves twenty-three relevant indexes about the timeliness, these factors of timeliness for patients seeing a doctor are judged. RESULTS: 36 681 people are checked for five years and 10 326 people(10 326 eyes) are suitable for surgery. Through analyzing sixteen relevant indexes about the timeliness , there are ten indexes which have Statistical Significance including in transportation, the distance for nearest medical aid post , care knowledge, population of family, income of family, respondents degree , the highest degree of family members type of work, structure of building, government subsidies. The first reason that the people can't be operated in time are economic difficulties, next are older and making children trouble for seven factors of no operation in time. The people for this three reason is more than 75% for not seeing a doctor in time. CONCLUSION: The key work of blindness prevention and treatment is the cataract surgery for our country.Eye doctors pay attention to new surgical technique , at the same time we should promote MSICS which is technique of low cost and have good effect of the operation.

Relevant factors of estrogen changes of myopia in adolescent females.

BACKGROUND: Gender is one of the risk factors accounting for the high prevalence of adolescent myopia. Considerable research results have shown that myopia incidence of female is higher than that of male. This study aimed to analyze the correlation between ocular parameters and serum estrogen level and to investigate the vision changes along with estrogen change in menstrual cycle of adolescent females. METHODS: A total of 120 young females aged between 15 and 16 years, diagnosed with myopia were recruited. Spherical lens, cylindrical lens, axis, interpupillary distance (IPD), and vision in each tested eye of the same subject were measured by automatic optometry and comprehensive optometry, with repetition of all measurements in the menstrual cycle of the 2 nd or 3 rd days, 14 th days, and 28 th days, respectively. Serum estradiol (E 2 ) levels were assayed by chemiluminescence immunoassay at the same three times points of the menstrual cycle mentioned above. RESULTS: In young females with myopia, the spherical lens showed a statistically significant difference among all different time in menstrual cycle (all P < 0.0001). The cylindrical lens, axis, and IPD were changed significantly during the menstrual cycle (P < 0.05). The vision of the three different time points in menstrual cycle had a significant difference (χ2 = 6.35, P = 0.042). The vision during the 14 th and 28 th day was higher compared to that on the 2 nd or 3 rd days (P = 0.021). Serum E 2 levels were significantly different at different time points in menstrual cycle (P < 0.05). E 2 levels reached its maximum value on the 14 th day and the minimum value on the 2 nd or 3 rd day. CONCLUSIONS: In adolescent females, the spherical lens and other related ocular parameters vary sensitively with different levels of E 2 in menstrual cycle. Vision in late menstrual stage is significantly higher than that in premenstrual stage.
