	Maldonado et al. [16]; Rothman et al. [9]	Vinekar et al. [7]; Vinekar et al. [31]
Number of patients	42	74
Birth weight (mean)	760 grams	1282 grams
Gestational age (mean)	26 weeks	31 weeks
Race	Mixed race; (African American 52%, White 40%, and Hispanic 7%)	Asian Indian (100%)
ROP stages included	0, 1, 2 and 3	0, 1 and 2
Incidence of macular edema, (%)	21 (50)	12 (16); (23 eyes of 146 eyes with ROP)
CME characteristics	Bulging fovea 13 (62)	Pattern A 52%; Pattern B 48%
Central foveal thickness	166 (91–499) microns	206 (108–304) microns
CME resolution (latest weeks)	43; 9 months	52
Visual acuity correlation (earliest checked)	9 months	3 months
Age range of visual correlation	9 months–5 years, (retrospective)	3–12 months (prospective)
Visual acuity mean at 9 months in logMAR	With edema (2): OD = 1.3, 1.3; OS = 1.9, 1.3; Without edema (2): OD = 0.8, 1; OS = 1, 1	Edema + ROP (11) = 1.30; Without edema + ROP (16) = 1.20; Preterm (17) = 0.98
