“…This may be attributed to the well-established quality control system and surgical training procedures implemented in the charity centers. Consultant ophthalmologists from urban centers provided on-site surgical training to local doctors, and supervised on sutureless large incision manual cataract extraction (SLIMCE)[ 11 ] [ 12 ]. After 6 months of hands-on training, these local surgeons were able to perform cataract surgery independently with encouraging outcomes.…”

PurposeTo estimate the prevalence and causes of blindness and visual impairment (VI), and report the outcomes of cataract surgery in Chaonan Region, Guangdong Province, southern ChinaDesignCross-sectional population-based surveyParticipantsA total of 3484 participants including 1397 men (40.1%) and 2087 women (59.9%) aged ≥50 years were examined (94.2% response rate).MethodA two-stage cluster sampling procedure was used to select 3700 participants aged ≥50 years from 74 clusters of Chaonan Region. Participants were examined according to the Rapid Assessment of Avoidable Blindness (RAAB) method. Blindness and visual impairment (VI) were defined by the World Health Organization criteria. Participants with visual acuity (VA) < 6/18 in either eye were examined by ophthalmologists. The primary causes of blindness and VI were reported with reference to the participant’s better eye.Main outcome measuresPrevalence and main causes of blindness, severe visual impairment (SVI), VI and the outcomes of cataract surgeryResultsThe standardized prevalence rates of blindness, SVI, and VI were 2.4% (95% confidence interval [CI], 1.9–2.9%), 1.0% (95% CI, 0.7–1.4%), and 6.4% (95% CI, 5.6%– 7.1%), respectively. The principal cause of blindness and SVI was cataract, accounting for 67.1% and 67.6% respectively, and the principal cause of VI was refractive error (46.9%). One hundred and fifty five out of 3484 (4.4%) people (211 eyes) had cataract surgery. Of the 211 eyes that had cataract surgery, 96.7% were pseudophakic. 67.2% of the 211 operated eyes had a presenting visual acuity (PVA) of 6/18 or better.ConclusionsThe prevalence of blindness, SVI, and VI was high among rural residents in Chaonan. Cataract remained the leading cause of avoidable blindness. Outcomes of cataract surgery performed in rural private clinics were suboptimal. Quality-control initiatives such as hands-on training program should be introduced to improve cataract surgery outcomes.

“…On this account, Project Vision, a non-governmental organization, was established to build a sustainable model to reduce cataract blindness in rural China. Project Vision’s first priority is to develop rural charity eye centers wherein local doctors are trained to provide high quality and low cost cataract surgery[ 11 ].…”

“…It is therefore not surprising that cataract remains the leading cause of vision impairment and blindness worldwide [3]. According to the latest information posted on the official website of Hellen Keller International (http://www.hki.org/working-worldwide/asia-pacific/china/) and a recent editorial article published in New England Journal of Medicine [4], cataract is responsible for at least 50% of the total (approximately 2.5 million) cases of blindness in China. As China's population is rapidly aging, age-related cataract is becoming an increasingly significant public health problem in the country.…”

Association of the Ephreceptor Tyrosinekinase-Type A2 (EPHA2) Gene Polymorphism rs3754334 with Age-Related Cataract Risk: A Meta-Analysis

et al. 2013

BackgroundRecent clinical studies have assessed the association of various polymorphisms on the ephreceptor tyrosinekinase-type A2 (EPHA2) with the risk for age-related cataract in populations of different ethnic/racial backgrounds, but inconsistent results have been obtained.ObjectiveThis meta-analysis aimed to identify if any polymorphism(s) might be commonly present in different ethnic/racial populations in association with the age-related cataract risk.MethodsThe PubMed and Web of Science databases (up to December 1, 2012) were searched for clinical studies on the association of EPHA2 polymorphisms with the risk for age-related cataract. The polymorphisms that were assessed in all eligible studies were analyzed for their association with the risk for age-related cataract using different models.ResultsThree studies were identified, which were conducted, respectively, on white Americans in the Unites States and on Asians in Indian and China. The polymorphism, rs3754334, was the only one studied in all these three studies and was therefore the focus of this meta-analysis. No publication bias or heterogeneity was found. Our analysis results demonstrated that rs3754334 was associated with the risk of any cataracts in the recessive (OR = 1.202, 95% CI: 1.051–1.375, P = 0.007) and Codominant (OR = 1.194, 95% CI: 1.035–1.378, P = 0.015) models, but its association with cortical or nuclear phenotype of age-related cataract was not evident.ConclusionPolymorphism, rs3754334, might be a variant on the EPHA2 gene that is commonly associated with the risk for age-related cataract in different ethnical and geographical populations.
