Incidence and characteristics of rhegmatogenous retinal detachment during coronavirus-19 pandemic: A French study.

ABSTRACT

PURPOSE: To assess the impact of the Covid-19 pandemic and subsequent lockdown on the number and clinical characteristics of patients with retinal detachment (RD) in a French public university eye hospital. METHODS: Single-center, retrospective non-interventional study. Patients consulting at the emergency room (ER) of Quinze-Vingts Hospital (France) for rhegmatogenous RD before and after instauration of the lockdown were reviewed. We compared the characteristics of patients with RD between the containment period (March17th - April27th,2020) and the period preceding the lockdown (February18th - March16th,2020). We compared the number of RD surgeries performed between the first month of lockdown (March17th - April19th,2020) and the corresponding period of 2019. Number of cases, delay between diagnosis and surgery, visual acuity was measured. RESULTS: During the first month of lockdown, 59 RDs were operated on, compared to 107 in the corresponding period in 2019 (-44,8%). Mean time from first symptoms to surgery was significantly higher during the lockdown 12.7 (11.3) days vs 7.6 (7.8) days (p = 0.031) before. During the lockdown, the mean BCVA was lower albeit the difference did not reach statistical significance (1.16 (0.9) during pre-containment vs 1.5 (0.9) during containment; p = 0.09). Reasonsfor delayed consultation were fear of Covid-19 (31%; p = 0.0001), absence of referral doctor (31%; p = 0.003) and difficulties in getting to public transport (10.3%;p = 0.859). CONCLUSION: Despite maintaining accessto emergency eye care facilitiesin our hospital, the lockdown affected visual health. Should the lockdown be reinstated, we postulate that a better information about eye care access for non-Covid emergencies may attenuate its effect on visual health.
