Purpose: To estimate the incidence and characteristics of surgery for retinal detachment (RD) at the Department of Ophthalmology, Odense University Hospital (OUH), Denmark. Methods: The Department of Ophthalmology, OUH, is the only retinal surgical department in the Region of Southern Denmark that covers a population of 1.2 million inhabitants. This was a retrospective chart review of all patients who underwent surgery for RD from January 1st 2010 to November 24th 2012. There were no exclusion criteria. Results: In the study period 678 operations were performed for RD. Of these, 84.8% (n=575) were primary operations, 14.5% (n=98) were re-operations and the remaining 0.7% (n=5) were not registered by type. The annual incidence of primary retinal detachment was 16.4 (95% CI: 15.1; 17.8) per 100,000 inhabitants. Pars plana vitrectomy (PPV) and sclera buckling were performed in 96.5% (n=654) and 3.2% (n=22), respectively. The remaining operations (0.3%, n=2) were not registered by type. In patients operated with PPV, instillation of intraocular gas was used in 58.7% (n=398) and instillation of silicone oil in 35.7% (n=242). Use of other vitreoretinal procedures was registered in 2.1% operations (n=14). RD was more common in males than in females (1.8:1), and the mean age at presentation was 59.0 years. RD was caused by ocular trauma in 5.8% (n=39) of the operated eyes, and among these 92.3 % (n=36) were men. There was a seasonal variation between Summer and Winter with 73 and 38 operations in June and January, respectively. Conclusion: An annual incidence of 16.4/100,000 inhabitants was found for primary RD in the Region of Southern Denmark. RD was associated with a seasonal distribution and was predominantly found in the population older than 50 years, and males. Results were consistent with previous studies. This retrospective review was part of a bigger PhD study for retinal detachment at OUH.
