“…Reports from Singapore, 103 Taiwan, 108 Hong Kong, 109 and Japan 110 have suggested that the prevalence of myopia is higher in East Asians than in Europeanderived populations. This has led to much debate on the aetiology of myopia and the role of genetic and environmental factors.…”

“…114 The economic boom evident in much of East Asia has been accompanied by higher standards of living and higher prevalence of myopia. 103,108,115,116 This is particularly evident in Singapore where increasing prosperity since the 1970s has led to a highly educated young population which has a higher rate of myopia than the older population. 103 If this really is due to a cohort effect rather than reflecting an actual change in refractive status of the eye with age, this will have profound implications for glaucoma screening and management, due to a likely shift in the balance between POAG and PACG incidence as the population ages.…”

Glaucoma is the leading cause of irreversible blindness worldwide. East Asians account for approximately half of all glaucoma sufferers. It is likely that trabeculectomy will be needed for many of these people as the intraocular pressure is to be maintained at a satisfactorily low level. The eyes of East Asian people differ in some aspects from those of other races. This review describes the natural history of the eye after trabeculectomy in East Asians.

Purpose To investigate the associated factors of foveoschisis and foveal detachment without macular hole in highly myopic eyes. Methods A cross-sectional study of 124 eyes of 68 highly myopic patients was performed. The patients underwent complete ocular examination, fundus photography, and optical coherence tomography (OCT). Results Of the 124 eyes, 10 (8%, 10/124) had foveoschisis or foveal detachment without a macular hole on OCT examination. On the basis of univariate analysis, six variables were associated with the pathologic changes, including age over 40 years (P ¼ 0.018), spherical equivalent over 10 D (P ¼ 0.042), axial length over 31 mm (P ¼ 0.001), macular chorioretinal atrophy (P ¼ 0.00003), posterior staphyloma (P ¼ 0.0003), and vitreoretinal interface factors, including epiretinal membrane, posterior vitreoschisis, and vitreomacular traction (P ¼ 0.00002). In the multivariate analysis, three factors were independently associated with foveoschisis and foveal detachment without macular hole in high myopia: axial length, macular chorioretinal atrophy, and vitreoretinal interface factors. Conclusions Foveoschisis and foveal detachment without macular hole are sight-threatening disorders in highly myopic eyes. Axial length, macular chorioretinal atrophy, and vitreoretinal interface factors were independently associated with these pathological conditions. Thus, both intraocular and outer ocular wall factors play important roles and merit further study.

“…The National Health and Nutrition Examination Survey of the US population, conducted from 1999 to 2004, reported the prevalence of myopia to be 42% of individuals in the 12 to 54-yearold age group, compared to 25% for the same age group 30 years previous [1,2]. In Singapore and Taiwan, prevalence has been estimated at 80% of young adults [3]. Within the next five years, it is estimated that myopia will affect nearly 2.5 billion people worldwide [4].…”

Purpose: To evaluate axial length measurements obtained over a three-year period in children undergoing Orthokeratology (Ortho-K).Methods: Patient records were identified from a specialty contact lens practice. Data were obtained from myopic patients who were prescribed Ortho-K wear. Demographic data at baseline included age at commencement of Ortho-K and ethnicity. Clinical data recorded at baseline and at years 1, 2 and 3 included subjective refraction, corneal topography, corneal curvature, axial length, pupil size, and lens design, changes in lens parameters, lens wear habits, wearing time and unaided visual acuity. The primary outcome measure was change in axial length during the study period.Results: 194 eyes of 97 subjects were included in data analysis. Mean age at start of Ortho-K was 10.4 years (SD=1.9). Mean axial length was 24.59 mm (SD=0.85) at baseline and 24.87 mm (SD=0.87) at the three year evaluation, for a mean change in axial length of 0.28 mm (SD=0.64). 65.5% of eyes (n=127) showed little or no change (<0.5 mm) in axial length during the study period. 20.1% of eyes (n=39) showed moderate increase in axial length of 0.5-1.0 mm and14.4% of eyes (n=28) showed >1.0 mm increase in axial length during the 3-year study period. Linear mixed regression analysis showed a significant association between older age at initiation of Ortho-K and less increase in axial length (p=0.0077). Axial length changes were not associated with duration of wear (both hours/night and nights/week) or baseline corneal curvature. Conclusion:Use of Ortho-K may help reduce axial length elongation in myopic eyes. Age of the initial treatment is a key factor. The baseline of cornea curvature and duration of the wear are not directly associated with treatment outcome. Of note, during the three-year study, 65.5% of treated eyes (n=127) showed a minimal or clinically insignificant increase of axial length (<0.5mm). Early treatment should be considered.
