ABSTRACT
With the alterations of people's living habits and environment,dry eye has become one of the most common diseases in ophthalmic clinic. Diabetes mellitus can cause a variety of ophthalmic complications, such as cataract and diabetic retinopathy. Recently, some studies show that there is higher incidence of dry eye in hyperglycemia and diabetic patients,and diabetes is one of the important risk factors for dry eye.However,the relevant mechanisms and clinical features of diabetic dry eye are not fully understood,and most studies only focus on patients with dry eyes.In this review,we discuss the prevalence,etiology,pathogenesis,clinical characteristics,prevention and treatment for diabetes-related dry eye.
ABSTRACT
AIM:To compare the efficiency of fibrin glue to suture technique in pterygium surgery performed with limbal autograft under different methods of anesthesia. METHODS: A prospective randomised clinical trial was carried out in 60 eyes of 55 patients operated for primary nasal pterygium, which were divided into two groups randomly: experimental group ( 30 eyes in 27 patients ) was under surface anesthesia ( oxybuprocaine ) and control group ( 30 eyes in 28 patients ) was under local anesthesia ( 20g/L lidocaine ). Autologous limbal graft taken from the superotemporal limbus was used to cover the sclera by a fibrin tissue adhesive after pterygium excision. Patients were followed up at least for 6mo. Time of operation, matching degree of graft and VAS score were mainly observed and recorded. RESULTS: In experimental group the average surgery time was shorter (P=0. 008) and matching degree of graft ( 93%) was better than control group ( 83%) , the differences had statistical significance(P CONCLUSION: The surface anesthesia is enough when using fibrin glue for graft fixation in pterygium surgery, which will shorten surgery time and get better matching degree of graft.
ABSTRACT
Objective To estimate the prevalence of cataract and its surgical coverage rate together with the burden related to bilateral cataract-blindness,among adults aged 40 or above in Gongshan county of Yunnan province and to evaluate the current cataract status and the efficacy of local cataract prevention program.Methods Cluster sampling was used.The protocol consisted of personal interview,pilot study,visual acuity checking,measuring the intraocular pressure; slit lamp microscopy and the fundus of the eye examination etc.Cataract was graded clinically using the Lens Opacity Classification System (LOCS) ]Ⅲ.Bilateral cataract-blindness burden,bilateral cataractblindness burden and cataract surgical coverage rate were calculated respectively,using two different criteria.Odds ratios (OR) were compared among different groups regarding age,gender,education,ethnic group and altitude of living area.Results Among the 1236 eligible residents,1116 (90.3％)were enrolled in the present study.The prevalence of cataract was 23.8％ among adults aged 40 or order.When the bilateral best refractive vision ＜3/60 was defined as the blindness criterion,the bilateral cataract-blindness burden showed as 1.3％,and cataract blindness surgical coverage rate was 50.0％.When the bilateral presenting vision ＜ 6/60 was defined as the blindness criterion,the bilateral cataract-blindness burden was 25.0％,and cataract blindness surgical coverage rate was 12.9％.The cataract surgical coverage rates were much lower and the bilateral cataract-blindness burden much higher in women,illiterates,living in high altitude areas and those who were aged 70 or above.Conclusion Cataract blindness was a serious public health problem in aged individuals and illiteracy in the residents of the studied areas.Poor prevention programs on cataract called for urgent action to be taken.
