Vitreous incarceration was found in 96.5% of the wounds without conjunctival bleb (
B0) (55.6% [140/252]) presented vitreous entrapment
V1, and 40.9% (103/252) [entrapment
V2]). Amongst the sclerotomies that showed subconjunctival leakage
B1, 81.8% of them exhibited vitreous incarceration (75.7% [25/33] showed incarceration
V1, and 6.1% [2/33] incarceration
V2). Finally, when the incisions with conjunctival blebs
B2 were studied, 14.3% of them had vitreous entrapment
V1 (1/7) and none of them presented vitreous strands
V2 (
Fig. 4). When we compared the presence of vitreous incarceration (
V0 or
V1+
V2) observed in the sclerotomies, according to the absence or presence of conjunctival bleb (
B0 or
B1+
B2), significant differences were found between the greater proportion of vitreous incarceration presented in the sclerotomies without conjunctival bleb (243/252) when compared with the less proportion of residual vitreous detected in sclerotomies with subconjunctival leakage (28/40) (
P < 0.001; Fisher's Exact test). When we compared the proportion of vitreous incarceration grades (
V0,
V1, or
V2) observed in the three sclerotomy subgroups, according to the conjunctival bleb grade detected (
B0,
B1, or
B2), significant differences were found (
P < 0.001; Kruskal-Wallis test). These differences were mainly based on the greater number of vitreous incarcerations
V2 observed in sclerotomies without conjunctival bleb, and the fewer number of vitreous entrapments
V1 presented in the sclerotomies with conjunctival bleb
B2 (
Fig. 4).
