Northern New Zealand Rhegmatogenous Retinal Detachment Study: epidemiology and risk factors

Abstract

The annual incidence of RRD in northern New Zealand is comparable to values reported for other parts of the world and, consistent with previous studies, the incidence of RRD was found to increase with age, and in association with trauma, high myopia and cataract surgery.

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

“…The following have been suggested as possible causes of the variation in incidence rates: (1) The definition of RRD differs among studies; for example, some studies only included surgery-requiring RRD [2,7]. Patients treated by retinal photocoagulation or cryotherapy alone were not counted in the present study, but in other studies, all patients with RRD were counted, regardless of the therapeutic method [3][4][5][6]. In addition, there has been variation in the inclusion of traumatic retinal detachment, retinal detachment associated with macular hole, recurrent RRD, and RRD after intraocular surgery.…”

“…(2) The demographic characteristics, such as age distribution, also differed among studies. In some previous studies, the incidences of RRD were higher in the elderly age group, with a peak at 50-79 years of age, than in younger subjects [1][2][3][4][5][6][7]. Similarly, the incidences of RRD were 18.2 and 13.2 per 100,000 people in the Netherlands [7] and Scotland [4], where 35% and 34% of the population were 50 years of age or older, respectively.…”

“…Similarly, the incidences of RRD were 18.2 and 13.2 per 100,000 people in the Netherlands [7] and Scotland [4], where 35% and 34% of the population were 50 years of age or older, respectively. In contrast, the incidences of RRD were 7.9 per 100,000 people and 11.7 per 100,000 people in China [1] and New Zealand [5], where 25% and 23% of the population were 50 years of age or older, respectively. We found a relatively high incidence of RRD in the present study compared with previous studies [1][2][3][4][5][6][7].…”

“…The results showed that the annual incidence of RRD in Kumamoto, Japan, between 2009 and 2011 was approximately 17 per 100,000 people. Previous studies have reported that the incidence of RRD was 7.98-18.2 per 100,000 people [1][2][3][4][5][6][7]. In ascending order, the incidence of RRD was 7.98 per 100,000 people in Beijing, China (1999-2000) [ [7].…”

“…Previous studies have reported that the annual incidence of RRD was 7.98-18.2 per 100,000 people [1][2][3][4][5][6][7]. Because the incidence of RRD is influenced by demographic characteristics [8], severe myopia [9,10], and history of cataract surgery [11,12], the incidence varies widely by region and age group.…”
