Purpose To examine the incidence of retinal detachments and to evaluate patient profiles and surgical characteristics. Methods Retrospective review of patients operated for primary retinal detachment ( RD) and redetachment between 2010 and 2012 at the Department of Ophthalmology, Odense University Hospital, Denmark. We included all RD such as rhegmatogenous retinal detachment ( RRD), tractional retinal detachment ( TRD) and exudative retinal detachment (ERD). Results In total, 779 RD surgeries were performed: 83.7% ( n = 652) primary operations and 16.3% ( n = 127) reoperation. For primary operation, pars plana vitrectomy ( PPV), scleral buckling and combined operations were performed in 95.1% ( n = 620), 4.6% ( n = 30) and 0.3% ( n = 2) respectively. Over time there was less use of silicone oil and greater use of gas tamponade (p = <0.001), less simultaneous cataract operations (p = <0.001), less use of cryotherapy (p = 0.045) and more use of peeling procedures (p = <0.001) in primary operations. The annual incidence of surgery for primary RD was 22.0 [95% confidence interval ( CI) 20.4-23.8] per 100 000 inhabitants aged >15 years. Retinal detachment (RD) was more common in males than females (1.8:1), and mean age at presentation was 61.8 years (standard deviations ± 12.3). The annual incidence for RRD and TRD operation was 20.72 (95% CI 19.11-22.43) and 1.25 (95% CI 0.9-1.7) per 100 000 inhabitants >15 years. Conclusion This study presents the first overall incidence for RD in Denmark. The highest incidence of RRD was among males aged 60 to 79 years, whereas TRD was among females at same age. Pars plana vitrectomy (PPV) was the preferred surgical technique, and during 2012 all RD patients were treated with PPV, independent of lens status and age. [ABSTRACT FROM AUTHOR]

Surgical approaches for rhegmatogenous retinal detachment (RRD) have evolved rapidly in the past century. This has resulted in an increase in the anatomical success rate from zero per cent in the beginning of the 1900s to now almost 100 per cent. Rhegmatogenous retinal detachment is regarded as an acute eye disease that needs immediate treatment. With the increasing number of cataract surgeries and an increased elderly population, the numbers of RRD occurrences are increasing. The aim of this thesis is to create knowledge on how treatment and care of RRD patients can be optimized. In the first paper, data on the incidence of RRD in Denmark are presented based on data from a nation register the National Patient Registry ( NPR). It was discovered that the incidence of RRD in Denmark is similar to previous reported numbers and that the incidence has been increasing due to increasing numbers of cataract surgeries and an increased elderly population. Using data from the NPR, we estimated that the risk of a RRD occurring on the fellow eye is 100 times larger than on the first eye and that middle aged men have the highest risk. Having an increase in the incidence of RRD we need to ensure that the patients are also treated in the most optimal way. To ensure this, an indicator is needed to monitor the quality at the different centres. This indicator presented in the second paper is based in the occurrence of redetachment. We define a detachment to be caused by poor surgery if the retina detaches within one year after initial surgery with pneumatic retinopexy, scleral buckling and VTX with gas, and one and a half years after surgery with VTX with oil. Also lack of oil removal within the first year is a failed operation. It is widely accepted that RRD is an acute disease but when should surgery be performed to attain the most optimal result? In the third paper, we evaluated the progression of posterior RRD with an optical coherence tomography to make an objective assessment of the movement. We found that the risk of a macula on RRD progressing to affect the fovea is small if the patient is postured appropriately. We found that the movement of the RRD is dynamic but the detachments will ultimately approach the fovea. Having an opportunity to postpone surgery without risking the outcome for the patient allows a more optimal surgery. The results of this thesis can be used by all health care systems to establish optimal conditions in the treatment of RRD. [ABSTRACT FROM AUTHOR]

Purpose: To study the development over time of the age‐ and sex‐standardized incidence of rhegmatogenous retinal detachment (RRD) in Denmark. Methods: Registry study, based on the Danish National Patient Registry data. End‐point: Individuals undergoing the first surgery for RRD. Results: During 2000–2016 we identified 11 769 individuals with a primary RRD surgery in either eye. The age‐ and sex‐standardized incidence rate of RRD increased by more than 50% during the study period. We found a significant increase in this incidence rate for both men and women older than 50 years, and in men, but not in women, younger than 50 years (p < 0.001). However, the increase of primary RRD surgery during the study period was most pronounced in men aged 50 years or older, where the rate of increase was 1.7 ± 0.1 cases per 100 000 person‐years per year (p < 10−11). Conclusion: The incidence of RRD is increasing, and this increase is primarily driven by men aged 50 years or older. [ABSTRACT FROM AUTHOR]
