“…Außerdem könnte auch die in den Sommermonaten verstärkte körperliche Aktivität im Freien eine Rolle spielen. Andere Arbeiten zeigten jedoch entweder keine saisonalen Schwankungen oder sogar eine Häufung in den Wintermonaten beispielsweise im Staat Kuwait [15,18,39]. Hierzu ist zu erwähnen, dass in Kuwait aufgrund der großen Hitze im Sommer eher der kühlere Winter zu mehr Außenaktivitäten und Tageslichtexposition animiert, was diese Trendumkehr erklären könnte [36].…”

“…Des Weiteren wird diskutiert, ob klimatische Faktoren einen Einfluss auf die Inzidenz der rhegmatogenen Netzhautablösung haben können. So wurde ein direkter Zusammenhang zwischen einer erhöhten durchschnittlichen Außentemperatur und einem vermehrten Auftreten von rhegmatogenen Netzhautablösungen vermutet [39]. Es wird angenommen, dass warme Temperaturen eine Verflüssigung des Glaskörpers begünstigen, während Kälte eher protektiv wirkt [36].…”

“…36 In contrast, a retrospective evaluation of RRD in Kuwait from 1981 to 1987 reported a peak incidence in winter (with the highest level in November) and a trough in the summer months. 38 These findings have not been replicated elsewhere.…”

“…Most studies describe a summer peak and winter trough; others vice versa and some no seasonal variation at all [35][36][37][38][39] . This is likely attributed to increased sun exposure and outdoor activities in summer³ .…”

Retinal detachment is a potentially blinding condition. It is caused by separation of neurosensory retina from the underlying retinal pigment epithelium. Despite treatment advances, functional results remain poor (with only 42% achieving 6/12 vision and only 28% if the macula is involved). There are three distinct types of retinal detachment: rhegmatogenous (RRD), tractional and exudative. For the purpose of this chapter we will focus on RRD.RRD demonstrates wide geographical variation with incidence reported between 6.3 and 17.9 per 100, 000¹ with 7300 new cases estimated annually in the UK² . Risk factors include myopia, increasing age and certain vitreoretinal conditions. Horseshoe tears, giant tears and round holes have been shown the most common along with lattice degeneration .Vitreoretinal traction is responsible for most RRD. As the vitreous becomes syneretic (liquefied) with age, a posterior vitreous detachment (PVD) occurs. In most cases, the vitreous separates from the retina without any sequelae. However, in certain eyes, strong vitreoretinal adhesions are present and the occurrence of a PVD can lead to a retinal tear; then, fluid from the liquefied vitreous can enter the sub-retinal space through the tear, leading to a retinal detachment.Several studies have investigated the epidemiology and risk factors associated with RRD.

“…Furthermore, a thorough literature review was undertaken, using a variety of search engines and databases. This yielded a total of 14 articles and reports [1][2][3][4][5][6][7][8][9][10][11][12][13][14] . The study was approved by the Institutional Review Board of the University.…”

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.
