	abstract = {<p>Aim: Retinal detachment (RD) is an ophthalmic emergency. Few studies addressed its incidence in the whole world. A recent study from Germany tried to estimate its incidence in a group of patients between 35 and 74 years of age in the city of Mainz. In our study, we aim to present the incidence of RD in the whole population in Germany, studying the trends and incidence per different age groups. Methods: We have analyzed the DRG records made by the institute for the hospital remuneration system and provided by the German federal statistics office. The data were collected using ICD- 10 H33.0, H33.2, and H33.4 for rhegmatogenous, serous, and tractional RD respectively. The files spanned the period between 2005 and 2019. We have calculated the crude and age-standardized incidence rates per 100,000 persons. We have analyzed the age and sex distributions, length of stay, patient comorbidity score, and geographical distribution. Results: We have analyzed the files of 389,138 admissions due to RD between 2005 to 2019. The number of admissions with all types of RD together increased from 20,457 in 2005, to 31,522 in 2019. This represented an increase in the crude incidence rate of RD from 25.1 to 37.7 per 100,000 respectively. The fraction of rhegmatogenous RD increased from 68\% in 2005 to 76\% in 2019. In General, the Age group of 70 to 74 showed the highest age-standardized incidence rate, however, this pattern was not the same for the whole study period. Interestingly, our study discovered a shift in the peak case numbers from the age group of the late sixties in 2005 to the late fifties/early sixties in 2019. The fraction of men diagnosed with rhegmatogenous RD increased from 59.15\% in 2005 to 64.3\% in 2019. The tractional type of RD showed a similar pattern. Apart from Bremen, all the federal stats showed an increase in the incidence rates over the study period. The duration of admission decreased from around 6 days in 2005 to 3.4 in 2019. In 2019, the reoperation rate was 12.2 \% in rhegmatogenous RD, compared to 14.14 \% in serous, and 21.2 \% in tractional RD. Patients{\textquoteright} comorbidity conditions were favorable in rhegmatogenous RD, while they were least favorable in tractional disease. Conclusion: The incidence of RD increased in Germany over the study period. The incidence rates also increased with age until the age group of the late sixties then declined again. The regulations enforced by the remuneration system resulted in decreasing the admission duration.</p>
