International incidence and temporal trends for rhegmatogenous retinal detachment: A systematic review and meta-analysis. Surv Ophthalmol 2024; 69:330-336. [PMID: 38000699 DOI: 10.1016/j.survophthal.2023.11.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2023] [Revised: 11/15/2023] [Accepted: 11/20/2023] [Indexed: 11/26/2023]
Abstract
We set out to estimate the international incidence of rhegmatogenous retinal detachment (RRD) and to evaluate its temporal trend over time. There is a lack of robust estimates on the worldwide incidence and trend for RRD, a major cause of acute vision loss. We conducted a systematic review of RRD incidence. The electronic databases PubMed, Scopus, and Thomson Reuters' Web of Science were searched from inception through 2nd June 2022. Random-effects meta-analysis model with logit transformation was performed to obtain pooled annual incidence estimates of RRD. Pooled analysis was performed to evaluate the temporal trend of RRD incidence of the 20,958 records identified from the database searches; 33 studies from 21 countries were included for analysis (274,836 cases of RRD in 273,977 persons). Three of the 6 global regions as defined by WHO had studies that met the inclusion and exclusion criteria of the study. The annual international incidence of RRD was estimated to be 12.17 (95% confidence interval [CI] 10.51-14.09) per 100,000 population; with an increasing temporal trend of RRD at 5.4 per 100,000 per decade (p 0.001) from 1997 to 2019. Amongst world regions, the RRD incidence was highest in Europe (14.52 [95% CI 11.79 - 17.88] per 100,000 population), followed by Western Pacific (10.55 [95% CI 8.71-12.75] per 100,000 population) and Regions of Americas (8.95 [95% CI 6.73-11.92] per 100,000 population). About one in 10,000 persons develop RRD each year. There is evidence of increasing trend for RRD incidence over time, with possibly doubling of the current incidence rate within the next 2 decades.

Abstract
Nowadays, automated disease diagnosis has become a vital role in the medical field due to the significant population expansion. An automated disease diagnostic approach assists clinicians in the diagnosis of disease by giving exact, consistent, and prompt results, along with minimizing the mortality rate. Retinal detachment has recently emerged as one of the most severe and acute ocular illnesses, spreading worldwide. Therefore, an automated and quickest diagnostic model should be implemented to diagnose retinal detachment at an early stage. This paper introduces a new hybrid approach of best basis stationary wavelet packet transform and modified VGG19-Bidirectional long short-term memory to detect retinal detachment using retinal fundus images automatically. In this paper, the best basis stationary wavelet packet transform is utilized for image analysis, modified VGG19-Bidirectional long short-term memory is employed as the deep feature extractors, and then obtained features are classified through the Adaptive boosting technique. The experimental outcomes demonstrate that our proposed method obtained 99.67% sensitivity, 95.95% specificity, 98.21% accuracy, 97.43% precision, 98.54% F1-score, and 0.9985 AUC. The model obtained the intended results on the presently accessible database, which may be enhanced further when additional RD images become accessible. The proposed approach aids ophthalmologists in identifying and easily treating RD patients.

Abstract
Myopia is a known risk factor for rhegmatogenous retinal detachment (RRD). Given global trends of increasing myopia, we aimed to determine the absolute risk (incidence rate) of RRD in non-myopes, myopes and high myopes in the United States over ten years. We performed a retrospective cohort study of 85,476,781 commercially insured patients enrolled in the Merative™ Marketscan® Research Database. The incidence rate of RRD in phakic patients in the United States was 39-fold higher in high myopes than non-myopes (868.83 per 100,000 person-years versus 22.44 per 100,000 person-years) and three-fold higher in myopes than non-myopes (67.51 per 100,000 person-years versus 22.44 per 100,000 person-years). The incidence rate was significantly higher in males in each category (P < 0.01). Combined, the incidence rate of RRD in phakic patients in the United States from 2007 to 2016 was 25.27 RRDs per 100,000 person-years, a rate higher than those in prior published studies in North America, South America, Europe, Asia, and Australia. The absolute risk of myopia and high myopia increased from 2007 to 2016. The risk of RRD in phakic high myopes rose with increasing age. Notably, the magnitude of increased risk of RRD in myopes varied substantially according to the minimum follow-up period in our models and should be accounted for when interpreting data analyses.

Abstract
Rhegmatogenous retinal detachment (RRD) is the most common form of retinal detachment (RD), affecting 1 in 10,000 patients per year. The condition has significant ocular morbidity, with a sizeable proportion of patients obtaining poor visual outcomes. Despite this, the genetics underpinning Idiopathic Retinal Detachment (IRD) remain poorly understood; this is likely due to small sample sizes in relevant studies. The majority of research pertains to the well-characterised Mende lian syndromes, such as Sticklers and Wagners, associated with RRD. Nevertheless, in recent years, there has been an increasing body of literature identifying the common genetic mutations and mechanisms associated with IRD. Several recent Genomic Wide Association Studies (GWAS) studies have identified a number of genetic loci related to the development of IRD. Our review aims to provide an up-to-date summary of the significant genetic mechanisms and associations of Idiopathic RRD.

Abstract
Purpose To investigate the incidence, seasonal variation, and differences among age, sex, and race for rhegmatogenous retinal detachment (RRD) repair, retinal break (RB) treatment, and posterior vitreous detachment (PVD) in the Intelligent Research in Sight (IRIS) Registry. Design Retrospective database study. Participants Patients in the IRIS Registry who underwent RRD repair, RB treatment, or cataract surgery (CS) based on Current Procedural Terminology codes and PVD diagnosis based on International Classification of Diseases, Ninth and Tenth Revision, codes. Methods Daily incidence rates were defined as the ratio of patients who underwent RRD repair or RB treatment and patients with a diagnosis of PVD to the total number of patients followed on a given day within the IRIS Registry. The CS group was included as a comparison for seasonal variation. Rates were stratified by decade of life, sex, and race. Main Outcome Measures Time series trends for incidence rates of RRD, RB, and PVD. Results A total of 7 115 774 patients received a diagnosis of incident PVD, 237 646 patients underwent RRD repair, and 359 022 patients underwent RB treatment. Also included were 5 940 448 patients who underwent CS. The mean daily incidence for RRD repair, RB treatment, PVD diagnosis, and CS were 0.46 per 100 000 patients, 0.70 per 100 000 patients, 13.90 per 100 000 patients, and 11.80 per 100 000 patients, respectively. Men showed higher incidence of RRD repair and RB treatment than women, whereas women showed higher incidence of PVD diagnosis. Rhegmatogenous retinal detachment incidence was higher in White people compared with other races. Seasonal decreases in PVD, RB treatment, RRD repair, and CS corresponded to national holidays, with larger decreases in winter months. Kaplan-Meier estimates showed that RRD repair and RB treatment typically occurred within 60 days of PVD diagnosis. Conclusions Within the IRIS Registry, the highest incidence of RRD was in the 6th and 7th decade of life. There was a higher incidence of RRD repair and RB treatment in men compared with women. The seasonal variation associated with national holidays was less pronounced for RRD repair and RB treatment.

Abstract
Background To determine the 12-year incidence of and trends in rhegmatogenous retinal detachment (RRD) requiring surgery in Korea. Methods This was a nationwide, population-based, retrospective study. We identified 53,179 patients with incident RRD requiring surgery using the Korean National Health Claims Database from 2004 to 2015. We estimated the crude incidence rates and age- and sex-standardized incidence rates per 100,000 person-years in each year during the study period. A joinpoint regression analysis was performed to determine the trend. Results The average annual incidence rate was 9.78 (95% CI: 9.70–9.86). Male patients showed an incidence rate (10.68 [95% CI: 10.57–10.80]) 1.20 times that of female patients (8.87 [95% CI: 8.76–8.98]). The incidence showed a bimodal distribution; the highest peak was in the 60–64 year age group (23.77 [95% CI: 23.18–24.35]) and the second peak was in the 20–24 year age group (7.68 [95% CI: 7.41–7.95]). An increasing trend of RRD incidence was observed in the total population throughout the study period using joinpoint analysis (annual percentage change [APC], 2.05; 95% CI: 0.7–3.4). The increasing trend was more prominent among individuals aged under 50 years (APC, 3.44; 95% CI: 2.3–4.6), while among those aged 50 years or above, the increasing incidence was observed only in male patients. Conclusions In Korea, the incidence of RRD has increased recently. People in the < 50 year age group accounted for the major part of this significant increase, which is related to the increasing incidence of myopia in the young generation in Asia.

Abstract
Objectives: To assess seasonal variations in the incidence of rhegmatogenous retinal detachment (RRD) in the Eastern Black Sea region of Turkey. Materials and Methods: Patients presenting due to primary RRD to a university hospital operating as a reference clinic in the region between 2011 and 2018 were evaluated retrospectively. Patients’ ages, sex, affected eye, and presentation times were recorded. Years were divided into months, quarters, seasons, and half-year periods, and these periods were analyzed in terms of differences in patient numbers. Results: Two hundred eighty-one eyes of 276 patients meeting the study criteria were included. The patients’ mean age was 60.2 years, and the male:female ratio was 1.35:1. Right and left eye rates were similar. Detachments were most common (49.4%) in the upper temporal quadrant. Eighty-nine patients (31.6%) had undergone uncomplicated phacoemulsification surgery a mean 2.7 years previously. The mean annual case number was 35.13±5.43, and no statistically significant variation was determined in case numbers by year (p=0.558). Analysis of all years revealed a monthly mean case number of 23.42±4.4, with the highest number of cases, 29 (10.3%), being seen in September and the lowest number, 13 (4.7%), in December. No statistically significant monthly variation was determined (p=0.613). Similarly, no statistically significant variation was observed in case numbers analyzed by quarter, season, or half-year (p>0.05). Conclusion: The incidence of cases of uncomplicated RRD does not exhibit seasonal variation in our region. We also think that since 31.6% had a history of cataract surgery, patients undergoing phacoemulsification surgery, even if uncomplicated, should be periodically assessed for detachment.

Abstract
Rhegmatogenous retinal detachment (RRD) is a potentially blinding disease, more common in the myopic population. This systematic review aimed to collect the existing literature on the incidence of RRD in myopic phakic eyes. MEDLINE, Embase, and the Cochrane Library were searched to identify eligible studies published until February 2020. In total 2715 publications were identified, of which only 3 were considered eligible and 2 as eligible with major limitations. Because of substantial differences between the included studies, a pooled analysis was not conducted. Summarizing the results and considering several limitations, an annual RRD incidence per 100 000 of 15 to 34 for mild myopia, 15 to 73 for moderate myopia, 102 to 128 for high myopia, and 287 in very highly myopic eyes was shown. Large well-designed studies are needed, including precise information on the refractive status or axial eye length, lens status, traumatic injuries, and intraocular surgeries during follow-up.

Abstract
PURPOSE The prevalence of myopia is increasing around the world, stimulating interest in methods to slow its progression. The primary justification for slowing myopia progression is to reduce the risk of vision loss through sight-threatening ocular pathologic features in later life. The article analyzes whether the potential benefits of slowing myopia progression by 1 diopter (D) justify the potential risks associated with treatments. METHODS First, the known risks associated with various methods of myopia control are summarized, with emphasis on contact lens wear. Based on available data, the risk of visual impairment and predicted years of visual impairment are estimated for a range of incidence levels. Next, the increased risk of potentially sight-threatening conditions associated with different levels of myopia are reviewed. Finally, a model of the risk of visual impairment as a function of myopia level is developed, and the years of visual impairment associated with various levels of myopia and the years of visual impairment that could be prevented with achievable levels of myopia control are estimated. RESULTS Assuming an incidence of microbial keratitis between 1 and 25 per 10 000 patient-years and that 15% of cases result in vision loss leads to the conclusion that between 38 and 945 patients need to be exposed to 5 years of wear to produce 5 years of vision loss. Each additional 1 D of myopia is associated with a 58%, 20%, 21%, and 30% increase in the risk of myopic maculopathy, open-angle glaucoma, posterior subcapsular cataract, and retinal detachment, respectively. The predicted mean years of visual impairment ranges from 4.42 in a person with myopia of -3 D to 9.56 in a person with myopia of -8 D, and a 1-D reduction would lower these by 0.74 and 1.21 years, respectively. CONCLUSIONS The potential benefits of myopia control outweigh the risks: the number needed to treat to prevent 5 years of visual impairment is between 4.1 and 6.8, whereas fewer than 1 in 38 will experience a loss of vision as a result of myopia control.

Abstract
Purpose To determine the risk between degree of myopia and myopic macular degeneration (MMD), retinal detachment (RD), cataract, open angle glaucoma (OAG), and blindness. Methods A systematic review and meta-analyses of studies published before June 2019 on myopia complications. Odds ratios (OR) per complication and spherical equivalent (SER) degree (low myopia SER < -0.5 to > -3.00 diopter [D]; moderate myopia SER ≤ -3.00 to > -6.00 D; high myopia SER ≤ -6.00 D) were calculated using fixed and random effects models. Results Low, moderate, and high myopia were all associated with increased risks of MMD (OR, 13.57, 95% confidence interval [CI], 6.18-29.79; OR, 72.74, 95% CI, 33.18-159.48; OR, 845.08, 95% CI, 230.05-3104.34, respectively); RD (OR, 3.15, 95% CI, 1.92-5.17; OR, 8.74, 95% CI, 7.28-10.50; OR, 12.62, 95% CI, 6.65-23.94, respectively); posterior subcapsular cataract (OR, 1.56, 95% CI, 1.32-1.84; OR, 2.55, 95% CI, 1.98-3.28; OR, 4.55, 95% CI, 2.66-7.75, respectively); nuclear cataract (OR, 1.79, 95% CI, 1.08-2.97; OR, 2.39, 95% CI, 1.03-5.55; OR, 2.87, 95% CI, 1.43-5.73, respectively); and OAG (OR, 1.59, 95% CI, 1.33-1.91; OR, 2.92, 95% CI, 1.89-4.52 for low and moderate/high myopia, respectively). The risk of visual impairment was strongly related to longer axial length, higher myopia degree, and age older than 60 years (OR, 1.71, 95% CI, 1.07-2.74; OR, 5.54, 95% CI, 3.12-9.85; and OR, 87.63, 95% CI, 34.50-222.58 for low, moderate, and high myopia in participants aged >60 years, respectively). Conclusions Although high myopia carries the highest risk of complications and visual impairment, low and moderate myopia also have considerable risks. These estimates should alert policy makers and health care professionals to make myopia a priority for prevention and treatment.

[PMID: 31899252 DOI: 10.1016/j.exer.2019.107907] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2019] [Revised: 11/05/2019] [Accepted: 12/30/2019] [Indexed: 02/05/2023]
Abstract
Rhegmatogenous retinal detachment (RRD) is the most common type of RD, the separation of neurosensory retina from the underlying retinal pigment epithelium. The RRD patients can be benefited from appropriate treatment if detected early, especially for the people predicted at high risk. In this study, we aimed to investigate the genetic association and clinical correlation of collagen type II alpha 1 (COL2A1) variants with sporadic RRD in a southern Chinese population. Totally 156 RRD patients and 254 control subjects were recruited, and 12 COL2A1 tag single nucleotide polymorphisms were genotyped by the TaqMan assay. The RRD patients had poorer visual acuity (P < 0.001) and lower intraocular pressure (IOP; P < 0.001) in their surgical eyes compared to the fellow eyes. The COL2A1 rs1793958 variant was significantly associated with RRD in the genotypic (P = 0.024), allelic (P = 0.011, odds ratio (OR) = 0.669), recessive (P = 0.011, OR = 0.384) and homozygous models (P = 0.007, OR = 0.348). RRD patients carrying the rs1793958 G allele had smaller retinal detachment area (P = 0.041) and smaller IOP differences (P = 0.046) between the surgical and fellow eyes compared to those carrying the wildtype AA genotype. In summary, this study revealed that the COL2A1 rs1793958 variant is associated with reduced risk of sporadic RRD, and patients carrying rs1793958 G allele have lower RRD severity.

Abstract
Retinal detachment can lead to severe visual loss if not treated timely. The early diagnosis of retinal detachment can improve the rate of successful reattachment and the visual results, especially before macular involvement. Manual retinal detachment screening is time-consuming and labour-intensive, which is difficult for large-scale clinical applications. In this study, we developed a cascaded deep learning system based on the ultra-widefield fundus images for automated retinal detachment detection and macula-on/off retinal detachment discerning. The performance of this system is reliable and comparable to an experienced ophthalmologist. In addition, this system can automatically provide guidance to patients regarding appropriate preoperative posturing to reduce retinal detachment progression and the urgency of retinal detachment repair. The implementation of this system on a global scale may drastically reduce the extent of vision impairment resulting from retinal detachment by providing timely identification and referral. Li et al. develop a cascaded deep learning system for automated retinal detachment and macular status detection based on ultra-widefield fundus (UWF) images. With reliable and comparable performance to an experienced opthamologist, this system can also provide guidance to patients regarding appropriate preoperative posturing to reduce RD progression.

Abstract
PURPOSE To examine the prevalence and incidence of rhegmatogenous retinal detachment (RRD) in Europe. METHODS A systematic review of the prevalence and incidence of RRD in Europe according to the meta-analyses of observational studies in epidemiology (MOOSE) guidelines was performed using the databases PubMed, Embase, and Web of Science followed by a meta-analysis of incidence data. RESULTS 658 studies were identified, 76 full-text articles were assessed, and 5 studies were eligible for meta-analysis. Random-effects pooled mean annual incidence of RRD in Europe was 13.3 cases per 100,000 inhabitants (95% CI: 11.3-15.6) based on the examination of 95,765 individuals from the 5 incidence studies. No European studies reporting prevalence of retinal detachment were identified. CONCLUSION Published articles on the prevalence and incidence of RRD in Europe are limited. Further epidemiological research is needed for adequate healthcare planning.

Abstract
PURPOSE To report the results and complications of scleral buckling for the treatment of rhegmatogenous retinal detachment (RRD) using 25-gauge chandelier endoillumination. METHODS A total of 61 patients (61 eyes) with RRD were treated with scleral buckling. For the sclera buckling procedure, a 25-gauge chandelier was inserted through the pars plana for intra-ocular illumination, and retinal tears were identified and treated with episcleral cryotherapy under surgical microscope. On postoperative days 1, 3 and 7, the intra-ocular pressure was measured by a non-contact tonometer. On postoperative months 1 and 3, ultrasound biomicroscopy was used to examine the pars plana incision. RESULTS In the surgical procedure, there was no lenticular or retinal damage due to the chandelier insertion. There was no conjunctival bleb formation at pars plana incision and no incidence of endophthalmitis after surgery. The mean intra-ocular pressure was 15.74 ± 2.98, 15.83 ± 2.76 and 16.14 ± 2.52 mmHg on postoperative days 1, 3 and 7, respectively. The one-time retinal reattachment rate was 93.4%. No visible vitreous incarceration was found in the incision of the pars plana. CONCLUSION There was no complication found due to the chandelier insertion in early postoperative period. Chandelier endoillumination is a feasible method for retinal visualization under surgical microscope during scleral buckling.

Abstract
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
PURPOSE We aimed to investigate the clinical variation of rhegmatogenous retinal detachments (RD) in patients of different ethnicities. METHODS Patients presenting with a primary RD from two ethnic groups were recruited from our tertiary referral hospital between August 2010 and December 2012. Patients who self-reported their ethnic origin either as European Caucasian (EC) or South Asian (SA) were included. Exclusion criteria included trauma, previous vitreoretinal procedures, age under 18 years, complicated cataract surgery and the presence of syndromes known to be associated with a high prevalence of RD. Detailed phenotypic data were collected. Descriptive and comparative statistical analyses were undertaken. RESULTS 1269 Patients were recruited. 1173 (92.4%) were EC. Mean age of onset was 58.3 years (EC) and 54.5 years (SA) (P=0.006). 75.3% EC and 58.4% SA were phakic (P<0.001). 12.8% of EC and 19.4% of SA patients had a lattice retinal degeneration in the affected eye (P=0.003). Refractive myopia was greater in SA patients (mean: -6.1DS) than EC (-4.2DS) (P=0.032). Additionally, SA patients had a greater mean axial length (25.65 mm) than EC (25.06 mm) (P=0.014). No differences were demonstrated in laterality, family history, type of retinal break or macular status. CONCLUSIONS SA patients present with RD at an earlier age and have a more severe phenotype than ECs. Future management strategies for RD may need to reflect these differences.

Abstract
PURPOSE To perform a short-term and a long-term cost-utility analysis of rhegmatogenous retinal detachment (RRD) surgery in Shanghai, China. METHODS A total of 117 patients who underwent RRD surgery at Shanghai First People's Hospital, Affiliated Shanghai Jiaotong University, and then underwent follow-up for at least 1 year, were included in the study. Costs associated with RRD surgery and time trade-off utility values before and after surgery were recorded. Short-term analysis was made for 1 year. Quality-adjusted life years (QALYs) gained by RRD surgery over the lifetime were calculated at a 3% discount rate in the long-term analysis. This study used the bootstrap method in statistical analysis and one-way sensitivity analyses to test robustness of the results. RESULTS Compared with no treatment, the mean incremental costs of RRD surgery was 11,384 Chinese yuan (CN¥) (US$1751); the mean additional QALYs gained was 0.05 (95% confidence interval [CI] 0.04-0.06) for 1 year and 0.88 (95% CI 0.64-1.13) for life expectancy; the incremental cost effectiveness ratio (ICER) was CN¥224,921 (US$34,603)/QALY for the short-term, and CN¥13,794 (US$2122)/QALY for the long-term. In short-term analysis, the ICER was CN¥150,087 (US$23,090)/QALY for scleral buckling surgery, and CN¥507,727 (US$78,112)/QALY for vitreous surgery. In the long-term analysis, the ICER was CN¥6280 (US$966)/QALY for scleral buckling, and CN¥30,756 (US$4732)/QALY for vitreous surgery. CONCLUSIONS For RRD patients, surgery increases QALYs. In a 1-year analysis, surgery is not a cost-effective treatment, however it is cost-effective over the lifetime.

Abstract
PURPOSE To define the incidence and demographic characteristics of rhegmatogenous retinal detachment (RRD) requiring surgery in Korea. DESIGN Nationwide population-based retrospective study. METHODS Patients who underwent surgery for RRD from 2007 to 2011 were retrospectively identified using the diagnostic code for RRD and the surgical codes for retinal detachment surgeries in the national claim database. The average incidence rate of RRD during the 5-year period was estimated using the population data of the 2010 Census in Korea. RESULTS A total of 24,928 surgically treated RRD cases were identified. The average incidence of surgery requiring RRD was 10.39 cases per 100,000 person-years [95% confidence interval (CI), 10.26-10.52). The incidence in men (11.32 cases per 100,000 person-years; 95% CI: 11.13-11.51) was significantly higher than that in women (9.47 cases per 100,000 person-years; 95% CI: 9.29-9.64) (p<0.001). The incidence of surgery requiring RRD showed a bimodal distribution across age groups, with one peak (28.55 cases per 100,000 person-years; 95% CI: 27.46-29.67) representing patients between 65 and 69 years of age and the second peak (approximately 8.5 per 100,000 person-years) representing patients between 20 and 29 years of age. The male-to-female ratio was approximately 1.0 for the peak-incidence age groups, whereas the ratio was higher for the other age groups. CONCLUSIONS The incidence of RRD in the Korean population was similar to that reported previously, with the peak incidence being lower than that in the Caucasian population. The age-specific RRD incidence pattern in Korea followed a bimodal distribution.

Abstract
Rhegmatogenous retinal detachment (RRD) is an important cause of vision loss and can potentially lead to blindness. The underlying pathogenesis is complex and incompletely understood. We applied a two-stage genetic association discovery phase followed by a replication phase in a combined total of 2833 RRD cases and 7871 controls. The discovery phase involved a genome-wide association scan of 867 affected individuals and 1953 controls from Scotland, followed by genotyping and testing 4347 highest ranking or candidate single nucleotide polymorphisms (SNPs) in independent sets of cases (1000) and controls (2912) of Dutch and British origin. None of the SNPs selected reached a Bonferroni-corrected threshold for significance (P < 1.27 × 10(-7)). The strongest association, for rs12960119 (P = 1.58 × 10(-7)) located within an intron of the SS18 gene. Further testing was carried out in independent case-control series from London (846 cases) and Croatia (120 cases). The combined meta-analysis identified one association reaching genome-wide significance for rs267738 (OR = 1.29, P = 2.11 × 10(-8)), a missense coding SNP and eQTL for CERS2 encoding the protein ceramide synthase 2. Several of the top signals showing suggestive significance in the combined meta-analysis encompassed genes with a documented role in cell adhesion or migration, including SS18, TIAM1, TSTA3 and LDB2, which warrant further investigation. This first genetic association study of RRD supports a polygenic component underlying RRD risk since 27.4% of the underlying RRD liability could be explained by the collective additive effects of the genotyped SNP from the discovery genome-wide scan.

Abstract
This study aimed to examine the seasonal variability of retinal detachment (RD) in Taiwan by using an 11-yr nationwide population database. This study also investigated the association of weather conditions, i.e., ambient temperature, relative humidity, rainfall, monthly hours of sunshine, and atmospheric pressure, with RD. Data were retrospectively collected from the Taiwan National Health Insurance Research Database. The study sample included 23 718 RD hospitalizations between January 1999 and December 2009. The incidence rate of RD/100 000 people over the 132 months was computed according to sex and age groupings of <20, 20-39, 40-59, and ≥60 yrs. Then, the association between climatic factors and the monthly RD incidence rate was examined. The ARIMA (autoregressive integrated moving average) method was also employed to test the seasonality of RD incidence rates and their association with climatic factors. The annual RD incidence rates were between 7.8 and 10.8 cases/100 000 people during the study period. A fairly similar seasonal pattern of monthly RD incidence rates was apparent for males and females and males and females combined. Rates were highest August through October, decreasing in November, and lowest in February. After adjusting for time, trend, and month, the ARIMA regression models for the male, female, and males and females combined consistently revealed the monthly RD incidence rate was significantly and positively associated with ambient temperature, but negatively associated with atmospheric pressure. The authors conclude that the monthly RD incidence rates were significantly associated with seasonality. The monthly RD incidence rates were positively associated with ambient temperature and negatively associated with atmospheric pressure.

Abstract
PURPOSE To describe the predisposing pathology and clinical features of all incident cases of rhegmatogenous retinal detachment (RRD) recruited in Scotland during a 2-year period. DESIGN Prospective surveillance study of incident cases of RRD. PARTICIPANTS All incident cases of RRD recruited as part of the Scottish Retinal Detachment Study. METHODS During a 2-year period, we coordinated a comprehensive system in which every case of primary RRD presenting to 1 of 6 vitreoretinal surgical sites in Scotland was examined and approached for study inclusion. MAIN OUTCOME MEASURES Rhegmatogenous retinal detachment incidence, predisposing features, and clinical characteristics. RESULTS A total of 1202 cases were recruited. Detailed clinical information was available on 1130 (94%) of cases. By causative break, the proportions of RRD were horseshoe tear (HST) associated with posterior vitreous detachment (PVD) in 86.2%, giant retinal tear (GRT) and PVD in 1.3%, non-PVD round hole (RH) in 4.9%, retinal dialysis in 5.9%, and retinoschisis RRD in 1.6%. One in 10 cases reported significant ocular trauma. One in 5 cases were pseudophakic. Round hole RRD more frequently presented with multiple retinal breaks compared with HST RRD (67.8% vs. 48.7%; P = 0.003). In PVD-associated RRD, 56.1% (95% confidence interval [CI], 53.8-58.3) of breaks were identified in the superotemporal retina. In non-PVD RRD, 54.6% (95% CI, 47.9-61.1) of breaks were inferotemporal, followed by superotemporal in 34.9% (95% CI, 28.7-41.5). Lattice degeneration was present in 18.7% of affected eyes and more common in RH RRD (35.7%) than in HST RRD (19.3%) (P = 0.003). Seven percent reported an affected first-degree relative, and these cases were significantly more myopic than nonfamilial cases. CONCLUSIONS More than 85% of RRD cases are associated with PVD and related tractional tears. Non-PVD RH RRD occurred in younger and more myopic individuals. The majority of cases are caused by more than 1 retinal break, and the macula is affected in more than 50% at presentation. Ocular trauma, previous cataract surgery, family history, and lattice degeneration are important predisposing features.

Abstract
Background Rhegmatogenous retinal detachment (RRD) is a potentially blinding condition and a common cause of ocular morbidity. Establishing an accurate estimate of disease incidence and distribution is an important first step in assessing the healthcare burden related to this condition and in subsequent planning and provision of treatment strategies. The aim of this study is to obtain a first estimate incidence of RRD in Scotland, to estimate the incidence of familial RRD and to describe the known associations of RRD within the study population. Methods/Design We have established a national prospective observational study seeking to identify and recruit all incident cases of RRD in the Scottish population over a 2 year period. After fully informed consent, all participants will have a blood sample taken and a full medical history and clinical examination performed including visual acuity, refraction, slit-lamp examination, intra-ocular pressure measurement and detailed fundal examination. We describe the study design and protocol. Conclusion This study will provide the first estimate of the annual incidence of RRD in Scotland. The findings of this study will be important in estimating the burden of disease and in the planning of future health care policy related to this condition. This study will also establish a genetic resource for a genome wide association study to investigate if certain genetic variants predispose to RRD.

Abstract
PURPOSE To investigate the neuron protective effect of recombined nerve growth factor (rNGF) on retinal cell damage induced by experimental retinal detachment. METHODS Experimental retinal detachment models were created in Sprague-Dawley rats by subretinal injection of sodium hyaluronate. Intravitreal injection of rNGF (5 microg/eye) or phosphate-buffered saline (PBS) was separately applied every 4 days after retinal detachment. The rat eyes were then observed and sacrificed at various time points. Morphologic changes were observed by light microscopy, electron microscopy, and cell counts. Apoptosis of retinal cells was detected by TUNEL assay. RESULTS After retinal detachment, most eyes from NGF-treated groups showed better organized structure of retinal cells than those from the PBS-treated control groups. Cell counts indicated that the nuclei numbers in the outer nuclear layer (ONL), inner nuclear layer (INL), and ganglion cell layer (GCL) of NGF-treated groups were significantly more than those from PBS-treated control group (p < 0.05) after retinal reattachment. TUNEL-positive cells were identified in ONL, INL, and GCL. They peaked at the fourth day after retinal detachment in both the NGF-treated groups and the control groups. But the cell counts of apoptosis revealed that the NGF-treated retina had less TUNEL-positive cells than the control groups (p < 0.05). CONCLUSIONS The results showed that intravitreal injection of exogenous NGF can protect retinal cells from degeneration and apoptosis in experimental retinal detachment. It may exert its neuroprotection effect by preventing the apoptosis of retinal cells after retinal detachment.

Abstract
PURPOSE To investigate the epidemiological characteristics and related risk factors for primary rhegmatogenous retinal detachment (RRD) in Taiwan. METHODS The case-control study was based on retrospective chart review of hospital patients treated for primary RRD from 1995 to 2001, inclusively. The preoperative fundus findings and refractive status were collected for each patient. Controls were selected from a nationwide survey of visual impairment in the adult population during the same period. Risk factors for RRD were analysed by logistic regression. A total of 1032 RRD cases and 3537 controls were enrolled for the study. RESULTS A pronounced bipeak pattern was evident in the age distribution for primary RRD in the third and sixth decades of life. Atrophic hole with lattice degeneration was preferential to younger (20-30 years) and highly myopic individuals (-7.4+/-5 D), whereas the flap tear tended to occur in middle-aged individuals (50-60 years) and those with moderate myopia (-4.1+/-5 D). The odds ratio for primary RRD with myopia, male gender, and older age (>40 years) were 1.33/D, 2.15, and 1.69, respectively. CONCLUSIONS Myopia is an important RRD risk factor for young Taiwanese. The increasing prevalence of myopia has predisposed the young population to RRD.
