The aim of the study was to look into the factors that contributed to the development of rhegmatogenous retinal detachment (RRD) in a group of patients whose surgery was postponed during COVID-19's top-level emergency response.

The medical histories of both consecutive RRD patients who underwent surgical treatment were reviewed retrospectively. The medical history, symptoms, and clinical signs of RRD development of the patient were all recorded. RRD progression was described as the presence of either choroidal detachment or proliferative vitreoretinopathy (PVR) progression during the quarantine period.

Results:
--79 eyes of 79 patients met the inclusion criteria and were included in the study. The median time was 14 days (3–61 days).

--There were 70 cases who did not present to the hospital within 1 week of the onset of visual symptoms.

--There were 69 macular-off cases at the presentation and 27 cases combined with choroidal detachment.

--There were 49 cases with PVR B, 22 cases with PVR C, 4 cases with PVR D, and 4 cases with anterior PVR.

--After the 14-day quarantine, 21 cases showed RRD progression, and 9 cases showed RRD regression at the time of surgery.

--Neither the time of onset of the visual symptom nor the time between presentation and admission was significantly different between the patients with RRD progression and patients without RRD progression.

--The combination of choroidal detachment (3.07) and retinal breaks located posterior to the equator (3.79) were factors related to the progression of RRD.

Finally, choroidal detachment and retinal breaks posterior to the equator were discovered to be RRD progression risk factors during the COVID-19 outbreak. According to ophthalmologists, RRD patients with these signs should have surgery as soon as possible.
