“…A significant reduction in the incidence of RD occurred in comparison to the same period of the previous four years ( Table 1 ). To reduce the impact of known seasonality in RDs, 15 , 16 the study period was compared with the same day interval of the previous years. The 2020 cohort included fewer patients than in the pre-COVID-19 period.…”

To compare the incidence and clinical characteristics of retinal detachments (RDs) diagnosed in a tertiary eye emergency department (EED) during the COVID-19 pandemic and in the corresponding period of the previous 4 years. Methods: EED consultations performed from February 21, 2020 (first national case of COVID-19 infection) to May 3, 2020 (end of lockdown imposed by national Government) and for the same date range of 2016-2019 (pre-COVID-19 period), and with a confirmed diagnosis of RD were collected and reviewed. The following demographical and clinical features have been analyzed: age, gender, etiology of RD, macular involvement, best corrected visual acuity (BCVA), and duration of experienced symptoms. Results: Eighty-two subjects (20.5±1.0 eyes/year) were diagnosed with RD in the pre-COVID-19 period, compared to 12 patients in the COVID-19 period (−41.5%). During the pandemic, patients complained symptoms for a median of 8.5 days (IQR, 1.7-15 days) before the EED consultation, while in the pre-COVID-19 period, they declared they had been symptomatic for 2 days (IQR, 1-4 days) (p=0.037); macula-off RD raised from 56% to 75% and no one reported trauma as a triggering event. Conclusion:During the COVID-19 pandemic, the rate of RD diagnosed in our EED decreased significantly and patients waited longer before asking for an ophthalmologic examination. These findings are probably due to the fear of contracting the COVID-19 infection attending hospital environments. Even if emergency departments are often misused by people suffering non-urgent conditions, patients complaining of sudden visual loss, visual field defects, or phosphenes should always and promptly attend an EED visit to prevent a worse prognosis.

“…Several authors have pointed out the higher incidence of RD in the summer and autumn months [1][2][3][4][5][6]. Other investigators found a small peak in September [7], A dif ferential analysis of the incidence of RD and of the spectral energy distribution of solar and cosmic radiation over a 1-year period was made and the results indicated a possible relationship between RD and the intensity of the shorter-wavelength radia tion (ultraviolet and blue light). However, the existence of a second October peak in ultraviolet radiation in addition to the Feb ruary peak makes such a correlation un likely.…”

The seasonal variation in the incidence of retinal detachment over the period from 1981 to 1987 inclusive was investigated. Highly significant associations were observed between this variation and both sunshine and temperature. Hence, it is suggested that heat or cold may be important additional factors in the development of retinal detachment in an already damaged retina. The occurrence of retinal detachment peaks over the winter months with the highest level being in the month of November, while there is a trough over the summer months.

“…This may be partly due to the relatively small sample size in our case series or alternatively as a result of the use of composite values for the weather measures, owing to the lack of daily measurements in the country. In Italy, Ghisolfi et al [4] found a significant correlation between RRD and light flux values. Similarly in Germany, Thelen et al [2] found a significant correlation between RRD and the astronomic duration of the day.…”

Seasonal Variation of Retinal Detachment in Lebanon

Background: The literature remains controversial regarding seasonal variation of rhegmatogenous retinal detachment (RRD). Methods: In this retrospective chart review, seasonal variation of RRD was examined based on the records of 211 consecutive patients operated for idiopathic RRD in one referral medical center over a 13-year period. Results: The number of eyes with RRD recorded per season was 46 in autumn, 46 in winter, 62 in spring and 57 in summer. There was a significant seasonal variation (p < 0.05) with an increase in RRD in the warm seasons (spring and summer) compared to the cold seasons (winter and autumn; 56 vs. 44%). Right eyes were more likely to be affected than left eyes (54 vs. 46%), and cases presented with a significantly younger age at onset in the warm than in the cold seasons (47 vs. 54 years, p = 0.007). A literature review of 8,533 cases including the present case series established further the seasonal variation of RRD (p < 0.001). Conclusion: There is convincing evidence for a seasonal variation of RRD in Lebanon and in the literature. This is likely to be related to sun exposure and outdoor activities in the warm seasons.
