Changes in corneal thickness following combined cataract and vitreous surgery.

Watanabe A, Shibata T, Takashina H, Tsuneoka H - BMC Res Notes (2015)

Bottom Line: Measurements were performed at the center and at points 3 mm superior, inferior, nasal and temporal to the center of the cornea.In both groups, postoperative corneal thickness at all points showed a significant increase at 1 day after the surgery when compared with the preoperative measurements (p < 0.05, paired t test).With the exception of the inferior point, the postoperative data for both groups showed a significant increase in the corneal thickness at 1 week after surgery compared with the preoperative measurements.

ABSTRACT

Background: We investigated changes in corneal thickness following combined cataract and vitreous surgery and determined whether such changes could be used as a criterion for evaluating the invasiveness of combined surgery.

Methods: This retrospective, consecutive, comparative study examined 35 eyes that had undergone combined cataract and 23-gauge vitrectomy for epiretinal membrane (ERM) (18 eyes) and rhegmatogenous retinal detachment (RRD) (17 eyes). Corneal thickness was measured before, 1 day, 1 week, and 1 and 3 months after the surgery. Measurements were performed at the center and at points 3 mm superior, inferior, nasal and temporal to the center of the cornea.

Results: In both groups, postoperative corneal thickness at all points showed a significant increase at 1 day after the surgery when compared with the preoperative measurements (p < 0.05, paired t test). At the center and inferior points, the mean corneal thickness in the RRD group was thicker than the mean of the ERM group at 1 day after surgery. With the exception of the inferior point, the postoperative data for both groups showed a significant increase in the corneal thickness at 1 week after surgery compared with the preoperative measurements. At 1 week after surgery, the mean corneal thickness in the RRD group at the center, inferior and temporal points was thicker than the mean of the ERM group.

Conclusions: Corneal thickness measurements are useful for assessing the extent of surgical stress that follows combined cataract and vitreous surgery.

Changes in corneal thickness at the points 3 mm temporal. In both groups, the postoperative corneal thickness was significantly increased at 1 day and 1 week after surgery when compared to the preoperative measurements (p < 0.005, paired t-test). In the RRD group, a significant increase in the corneal thickness was noted for the mean of the postoperative data at 1 month after the surgery when compared with the preoperative measurements (p < 0.005, paired t-test). The mean corneal thickness at 1 week after surgery in the RRD group was thicker than the mean of the ERM group (p < 0.05, t-test)

Fig5: Changes in corneal thickness at the points 3 mm temporal. In both groups, the postoperative corneal thickness was significantly increased at 1 day and 1 week after surgery when compared to the preoperative measurements (p < 0.005, paired t-test). In the RRD group, a significant increase in the corneal thickness was noted for the mean of the postoperative data at 1 month after the surgery when compared with the preoperative measurements (p < 0.005, paired t-test). The mean corneal thickness at 1 week after surgery in the RRD group was thicker than the mean of the ERM group (p < 0.05, t-test)

Mentions: Figures 1, 2, 3, 4, 5 show the results for the comparisons of the corneal thickness changes between the ERM and RRD groups. No significant differences were apparent for the preoperative thickness measurements at any of the measurement points between the two groups (t-test center: p = 0.18, superior: p = 0.81, inferior: p = 0.30, nasal: p = 0.51, temporal: p = 0.69).Fig. 1
