---|---|---|---|---|---|---|---|
Current Study | 85 infants (169 eyes) | 28 (2) | 976 (269) | 36 (0.6) | 60% | 0: 95 eyes 1: 29 eyes 2: 42 eyes 3: 3 eyes* |
Prevalence of macular edema increased with higher stages of ROP |
Zepeda et al, 201830 | 65 infants | 28 (2.7) | 997 (286) | 34 (3) | 40% | 0: 43 eyes 1: 8 eyes 2: 4 eyes 3: 10 eyes |
Association between macular edema and ROP not tested in this study. |
Erol et al, 201411 | 179 infants (358 eyes) | 30.9 (2.7) | 1609 (477) | 38.2 (3.9) | 38% | 1: 82 eyes 2: 28 eyes 3: 16 eyes |
The presence of macular edema increased with increasing ROP stage |
Dubis et al, 201312 | 46 infants | 27 (3) | 914 (358) | 30-57 | 56% | 0: 17 infants 1: 4 infants 2: 8 infants 3: 12 infants 4A: 2 infants |
No association between the most severe ROP stages and the presence of macular edema |
Maldonado et al, 20128 | 42 infants | 26 (1.8) (median) | 760 (272) (median) | 34 (1.6) (median) | 50% | 0: 13 infants 1: 6 infants 2: 17 infants 3: 6 infants |
Increased severity of edema was associated with plus disease, higher ROP stage and subsequent laser treatment |
Vinekar et al, 201110 | 74 infants (146 eyes) | 31.2 (2.32) | 1282 | 37 (2.7) | 29% of stage 2 | 1: 27 eyes 2: 79 eyes |
Macular edema was present only in Stage 2 eyes |
SD: Standard deviation; PMA: postmenstrual age; ROP: retinopathy of prematurity
Stage 3 not included in the analysis due to small numbers
