Abstract: Objective To analyze the prognostic factors in patients with high myopia (HM) combined with choroidal detachment retinal detachment(RRD-CD). Design Retrospective case series. Participants 836 patients with HM and RRD-CD of Beijing Tongren Hospital from 2004 to 2018. Methods A retrospective chart review was carried out on all patients with HM and RRD-CD having surgical treatment. Recurrence rate was calculated and risk factors of recurrence RRD were analyzed using Logistic regression analysis. Main Outcome Measures Operation success rate, risk factors of recurrence RRD. Results A total of 836 patients with HM complicated with RRD-CD were included, with an average age of 56.51±12.14 years; 518 cases (61.9%) were male, 434 cases (51.9%) had right eye disease, and 22.7% had retinal detachment without reattachment. Compared with the patients with retinal reattachment, the age of patients without reattachment was younger, and the differences in preoperative visual acuity, axial length, lens state, retinal hole, PVR grade and operation method were statistically significant. Age [odds ratio (OR)=0.972, 95% confidence interval (95% CI), 0.967-0.989], preoperative visual acuity (OR=1.898, 95% CI: 1.297-2.777), intraocular lens (OR=1.860, 95% CI: 1.255-2.758), axial length more than 30 mm (OR=1.718, 95% CI: 1.240-2.379), giant retinal hole (OR=2.464, 95% CI: 1.495-4.063) and PVR Grade D (OR=1.551, 95% CI: 1.046-2.300) was the risk factor for retinal detachment without reattachment. Conclusions High myopia patients with RRD-CD have a large proportion of males. Middle aged patients with ultra-high myopia, intraocular lens, giant retinal hole and PVD grade D have low success rate of the first operation, and retinal detachment is easy to relapse.
