“…17 In this survey, CO was the most frequent type, followed by NO, and then PSC, a finding reported in another study in western Nigeria (Table 5), 18 Tanzania, 19 and surveys in Barbados 20 and in the United States of people of African descent, 21 and Sri Lanka. 22 This contrasts with surveys in India, 6,23,24 Australia, 25 Taiwan, 26 Finland, 27 China, 28 and Myanmar where NO predominated. 29 More population-based data on the morphological types of opacities are required from Africa to explore reasons for the differences between regions.…”

“…Female gender is a well-described risk factor for cataract [7][8][9][10][11] though not all studies have found a difference in cataract prevalence between males and females [12,13]. The reduction in female hormones encountered during menopause may provide part of the explanation for the higher prevalence of cataract in females since hormon replacement therapy has been shown to prevent or postpone cataract development [14].…”

performed from 2002 to 2010 (excluding congenital and childhood cataracts) were drawn from the database yielding a total of 14,701 eyes (9,474 first eye surgeries and 5,227 second eye surgeries). To avoid problems with inter-eye interaction, the analyses were separated into first eye surgeries and second eye surgeries. However, only second eyes that were operated on within one year of the first eye were included in the second eye analyses (n=4.677). Thus, 550 eyes that were operated more than 1 year later than the first eye were excluded from the study.At the pre-operative visit all patients had a full ophthalmic examination including determination of best corrected visual acuity and a thorough slitlamp examination after pharmaceutical pupil dilation as well as biometric measurements including determination of axial length and radii of curvatures. Furthermore, patients were interviewed about cataract related symptoms as well as general health status. Any ocular co-morbidities were evaluated. For the statistical analyses, patients were grouped into those with ocular co-morbidities thought to be of significance for the visual acuity (e.g. age-related macular degeneration, glaucoma, previous retinal detachment, or previous vitreoretinal surgery) and those who did not have visually significant ocular co-morbidity (e.g. no other eye disease except cataract or visually insignificant eye disease such as blefaritis).Statistical analyses were performed using the SAS computer AbstractBackground: Due to the increasing proportion of elderly citizens the need for cataract surgery is expected to increase markedly within the next two decades but also the indication level for cataract surgery will influence the need for surgery. The aim of the present study was to examine if the indication for cataract surgery has remained stable over an eight year period in a university clinic setting in the Capitol Region of Copenhagen, Denmark.Methods: All pre-operative visits from 2002 to 2010 were evaluated yielding a total of 14,701 eyes (9,474 first eye surgeries and 5,227 second eye surgeries). Information was drawn from a database where pre-, peri-and postoperative data regarding all cataract surgeries (except for congenital and childhood cataract) performed at the clinic had been entered at the time of examination/surgery. Evaluation of the indication level for cataract surgery was assessed primarily based on visual acuity. Results:In the 8 year period, mean visual acuity increased significantly from 0.18 to 0.24 Snellen (corresponding to 0.74 to 0.62 logMAR) in the eyes that underwent surgery first and in second eyes from 0.29 to 0.41 Snellen (corresponding to 0.54 to 0.39 LogMAR, respectively, p-values <0.0001) and concomittantly the mean age of patients at the time of surgery decreased from 75.4 to 71.6 years in females and 72.1 to 69.1 years in males. Conclusion:During the time period from 2002 to 2010 the indication for cataract surgery changed towards patients being operated at better visual acuities and at younger ages. In the ...

“…Considering cataract prevalence in adults of the general population, the range varied from 33.2% in central Sri Lanka (Athanasiov et al 2010) to 40.4% in central Myanmar (Athanasiov et al 2008), compared to a prevalence in outdoor workers, ranging from 37.2% in a sample of agricultural workers from Tibet to 42.4% in mountain guides from France (El Chehab et al 2012) and 42.8% in outdoor workers from north Pakistan (Burton et al 1997). A lower prevalence (25.4%) was reported in a group of younger salt workers in India (Cherian et al 2015).…”

Cataract is currently the primary cause of blindness worldwide, and one of its main risk factors is solar ultraviolet radiation exposure. According to the localization of lens opacities, three main subtypes of cataract are recognized: nuclear, cortical and posterior subcapsular cataract. One of the main determinants of individual long-term solar radiation exposure is outdoor work. We systematically reviewed scientific literature from the last 20 years to update the recent development of research on the risk of cataract in outdoor workers and on the specific subtypes involved, also investigating the methods applied to evaluate the occupational risk. A total of 15 studies were included in the review, of which 12 showed a positive association. The studies confirm the relationship of long-term occupational solar radiation exposure with cortical cataract and give new support for nuclear cataract, although no substantial new data were available to support a relation with the posterior subcapsular subtype. In most of the studies, the exposure assessment was not adequate to support a representative evaluation of the ocular risk; however, outdoor work is clearly a relevant risk factor for cataract. Further research providing a better evaluation of the relation between solar radiation exposure levels and lens damage in workers is needed and aimed to establish adequate occupational exposure limits and better preventive measures, studying also their effectiveness.
