          Abstract

          Rhegmatogenous retinal detachment (RRD) frequency was observed to be higher with an increase in the daily temperature range. This showed that a wide daily range of temperature, rather than the absolute value of the temperature, is associated with the occurrence of RRD. Purpose. To investigate the association between the frequency of rhegmatogenous retinal detachment (RRD) and the atmospheric temperature. Method. A retrospective review of consecutive eyes that had undergone primary RRD surgery from 1996 to 2016 at Chungbuk National University Hospital was conducted. Temperature data (highest, lowest, and mean daily temperatures and daily temperature range) in Chungbuk Province were obtained from the Korean Meteorological Administration database. We investigated the relationship between the daily temperature range and the frequency of RRD surgery. We also analyzed the association between various temperature data and the frequency of RRD surgery. Result. There were 1,394 RRD surgeries from 1996 to 2016. Among them, 974 eyes were included in this study. The monthly average number of RRD operations showed a bimodal peak (in April and October) throughout the year. With the same tendency as the frequency of RRD, the monthly average of the daily temperature range over 1 year also showed a bimodal peak in April and October. There was a significant positive correlation between the monthly average of the daily temperature range and the number of RRD surgeries ( r = 0.297, P < 0.001). However, there were no associations between RRD frequency and the mean temperature, highest temperature, and lowest temperature. Conclusion. The higher the daily temperature range, the higher was the RRD frequency observed. We speculated that dynamic changes in temperature during the day may affect degrees in chorioretinal adhesion and liquefaction of the vitreous, which may eventually result in retinal detachment. Therefore, further experimental studies on the correlation between temperature changes and retinal detachment are needed.

          Posterior vitreous detachment: evolution and complications of its early stages.

          To summarize emerging concepts regarding the onset and progression, traction effects, and complications of the early stages of age-related posterior vitreous detachment (PVD). Interpretive essay. Review and synthesis of selected literature, with clinical illustrations, interpretation, and perspective. Imaging of the vitreoretinal interface with optical coherence tomography has shown that PVD begins in the perifoveal macula. Recent longitudinal studies have demonstrated conclusively that early PVD stages persist chronically and progress slowly over months to years. Vitreous traction forces resulting from perifoveal PVD with a small vitreofoveolar adhesion (500 microm or less) may cause localized cystoid foveal thickening or one of several macular hole conditions. Traction associated with larger adhesion zones may cause or exacerbate a separate group of macular disorders. Ultrastructural studies suggest that epiretinal membrane develops from cortical vitreous remnants left on the retinal surface after PVD and plays an important role in traction vitreomaculopathies. Age-related PVD is an insidious, chronic event that begins in the perifoveal macula and evolves over a prolonged period before vitreopapillary separation. Although asymptomatic in most individuals, its early stages may be complicated by a variety of macular and optic disc pathologic features, determined in part by the size and strength of the residual vitreoretinal adhesion.

            Epidemiology of retinal detachment.

            A survey of rhegmatogenous retinal detachment during 1976 was conducted on the population of Iowa. The annual incidences (per 100,000 populations) of four types of detachment were determined: nontraumatic phakic (6.1), traumatic phakic (1.0), nontraumatic aphakic (4.9), and traumatic aphakic (0.4). The incidences of nontraumatic phakic detachment for men and women were similar, although there was a preponderance of women that reflected their greater representation in the general population. The proportions of men were significantly higher in traumatic detachments compared with nontraumatic detachments. Men tended to be younger than women for all types of detachment; however, only in nontraumatic aphakic detachment was there a significant difference between mean ages. There was an insignificant preponderance of right eye involvement in all four detachment groups.

              Five Year Nationwide Incidence of Rhegmatogenous Retinal Detachment Requiring Surgery in Korea

              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.
