Correlation between the Proportion of Patients with Ocular Findings and Duration of Disease

	No.	Duration of Disease (days)			Correlation Coefficient	P Value∗
		1–10	11–20	21–38
Ocular symptoms, no. (%)					0.111	0.22
Yes	8	1 (12.5)	4 (50.0)	3 (37.5)
No	113	45 (39.8)	35 (31.0)	33 (29.2)
Conjunctival SARS-CoV-2 detection, no∙ (%)					0.074	0.42
+	3	0 (0.0)	2 (66.7)	1 (33.3)
±	4	1 (25.0)	2 (50.0)	1 (25.0)
–	114	45 (39.5)	35 (30.7)	34 (29.8)

SARS-CoV-2 = severe acute respiratory syndrome coronavirus 2; + = positive (cycle threshold values, <37); ± = suspicious (cycle threshold values, 37–40); – = negative (no cycle threshold value or cycle threshold values = 40).
