Characteristics of primary rhegmatogenous retinal detachment in Taiwan

Abstract

Purpose To investigate the epidemiological characteristics and related risk factors for primary rhegmatogenous retinal detachment (RRD) in Taiwan. Methods The case-control study was based on retrospective chart review of hospital patients treated for primary RRD from 1995 to 2001, inclusively. The preoperative fundus findings and refractive status were collected for each patient. Controls were selected from a nationwide survey of visual impairment in the adult population during the same period. Risk factors for RRD were analysed by logistic regression. A total of 1032 RRD cases and 3537 controls were enrolled for the study. Results A pronounced bipeak pattern was evident in the age distribution for primary RRD in the third and sixth decades of life. Atrophic hole with lattice degeneration was preferential to younger (20-30 years) and highly myopic individuals (À7.475 D), whereas the flap tear tended to occur in middle-aged individuals (50-60 years) and those with moderate myopia (À4.175 D). The odds ratio for primary RRD with myopia, male gender, and older age (440 years) were 1.33/D, 2.15, and 1.69, respectively. Conclusions Myopia is an important RRD risk factor for young Taiwanese. The increasing prevalence of myopia has predisposed the young population to RRD.

Epidemiology and clinical characteristics of rhegmatogenous retinal detachment in Taiwan

“…Besides, we noted bimodal age peaks of RRD in our study, which has also been reported in previous studies on Chinese patients 12 14. As high myopia is an important risk factor for RRD in younger patients,14 the higher incidence of RRD in the young patients in this study may be due to the high prevalence of myopia in these patients in Taiwan 7…”

“…The median (50 years) and mean (47.76±0.67 years) ages in the present study are younger than reports from Western countries,9 10 13 but similar or older than reports including other Chinese populations 11 14. Differences in the mean age of patients with RRD between different ethnic groups was also reported by Chandra et al ,15 who reported that patients from South Asia had a younger age at onset and more myopic refraction than patients in Europe.…”

Seasonal Variation of Retinal Detachment in Lebanon

“…In contrast, Chou et al [20] found males to be significantly more prone to RRD than females by an odds ratio of 2.15. Similarly, in our case series, the male-to-female ratio was 3.3.…”

The Prevalence and Impact of High Myopia

“…67 This increased risk with increasing refractive error has been quoted as an odds ratio of 1.33 times per diopter of myopia in the adult Taiwanese population. 68 Retinal detachment is often a secondary complication of a macular hole. Macular holes in themselves can be devastating to visual acuity.…”
