Abstract
BackgroudChoroidal detachment (CD) following primary rhegmatogenous retinal detachment (RRD) is a special type of RRD. The purpose of this study is to investigate the potential risk factors of RRD with CD in a Chinese population.MethodsAll of 201 consecutive RRD with CD patients and 210 RRD without CD patients were enrolled in this case–control retrospective study. The clinical data from these cases were reviewed here. Patients were undergone scleral buckling or encircling or both, or pars plana vitrectomy with or without scleral buckling or encircling or both according the patients’ condition. The incidence of RRD with CD in this Chinese population was measured, and the potential risk factors for the development of RRD with CD were investigated by multivariate logistic regression analysis.ResultsIn this population, the incidence of RRD with CD was 8.6 %. The incidence of RRD with CD was significantly higher in patients with macular hole (P < 0.05), retinal breaks located posterior to the equator (P < 0.05), and total detachment (P < 0.05). Furthermore, the incidence of RRD with CD was significantly higher in patients with longer axial length (P < 0.05) only when ages, IOP, AL and duration time was set for categorical variables.ConclusionsHypotony, retinal breaks located posteriorly especially macular hole, longer axial length, and the whole retinal detachment might be the potential risk factors for the development of CD in RRD patients.
Highlights
The worldwide occurrence of choroidal detachment (CD) following primary rhegmatogenous retinal detachment (RRD) is rare, affecting only 2 %–4.5 % of RRD cases [1,2,3], but the incidence is higher (1.5 %–18.1 %) in China [4]
A total of 2,348 consecutive cases that underwent scleral buckling or pars plana vitrectomy (PPV) for retinal reattachment at the Department of Ophthalmology at Beijing Tongren Hospital affiliated with Capital Medical University, were reviewed in this study
All 201 patients with RRD with CD patients, and 210 patients with RD and no CD, who were randomly selected from 2,147 consecutive patients, were enrolled in this study
Summary
The worldwide occurrence of choroidal detachment (CD) following primary rhegmatogenous retinal detachment (RRD) is rare, affecting only 2 %–4.5 % of RRD cases [1,2,3], but the incidence is higher (1.5 %–18.1 %) in China [4]. Because of the high incidence of proliferative vitreoretinopathy after surgery,, varying from 35.4 %–52.4 %, [3, 6] the results of conventional scleral buckling in eyes with RRD and CD have been reported to be relatively poor. This unfavorable prognosis has been attributed to poor visualization, difficult identification of causative breaks, In most cases, CD occurs after the development of RRD. Due to the small sample size, these studies were inconclusive
