Racial Difference in the Incidence of Retinal Detachment in Singapore

Abstract

To determine the incidence of retinal detachment (RD) operations in a multiracial Southeast Asian population. Design: Population-based incidence study using a universal medical savings database in Singapore. Methods: Information on all RD operations performed for rhegmatogenous RD (International Classification of Diseases, Ninth Revision, Clinical Modification code 361.0) between 1993 and 1996 was retrieved and analyzed from a population-wide, government-administered medical savings database. Exudative, tractional, and unoperated-on rhegmatogenous RD are excluded. The 1990 Singapore population census was used to allow an estimation of age-, sex-, and race-specific annual incidence of RD.

Ethnic differences in the demand incidence of retinal detachments in two districts in the West Midlands

“…5 This has been confirmed in our study in both populations with a demand incidence of 4.6 and 2.0 per 100 000 for Wolverhampton and Walsall, respectively (Table 2).…”

“…There have been few studies 5,6 analysing racial differences in the incidence of retinal detachment. Wong et al 5 have shown a three-fold higher incidence of retinal detachment in Chinese compared to Indians, and alluded to the cause being the increased prevalence of myopia in Chinese compared to Malays.…”

“…5,6 The demand incidence is of importance to ophthalmologists in planning vitreoretinal services as it specifically involves only patients presenting for medical attention and therefore considers the population creating the work load. This paper examines the demand incidence and ethnic differences of RRD in two defined populations of the West Midlands ( Figure 1a).…”

Demand incidence of retinal detachment in Brazil

“…These data are not dissimilar from results in Sweden (10.6:100 000), 8 and Singapore (10.5:100 000). 9 Our calculations underestimate the actual incidences. The profile of private health plans shows that the Southeast Region concentrates 70% of those covered people in Brazil.…”

The Incidence of Rhegmatogenous Retinal Detachment in Kumamoto, Japan between 2009 and 2011

“…Our study found that the incidence of RRD was higher in males than in females, with no marked difference between the sexes in refractive status, which are risk factors of RRD. Ocular trauma was also a risk factor of RRD in males [7,20]. However, traumatic retinal detachment was not included in our study.…”
