Corneal thickness was measured prior to as well as following 1 week, 1 month, and 3 months after surgery. Measurements were performed at the center and at points 3 mm superior, inferior, nasal, and temporal to the center.Results: Across the 20 cases, postoperative data showed a significant increase at 1 week after surgery at all points, but recovery to preoperative levels was evident only 1 month after surgery (P &lt; 0.05, paired t-test test). In the rhegmatogenous retinal detachment group (n = 9), mean corneal thickness 1 week after vitrectomy showed a significant increase at all points, but had recovered to preoperative levels by 1 month. In the proliferative diabetic retinopathy group (n = 5), mean corneal thickness at 1 week after vitrectomy showed a significant increase at central, inferior, and temporal points, but had recovered to preoperative levels by 1 month. In the epiretinal membrane group (n = 6), 6 3 months after surgery (P &lt; 0.05, Wilcoxon signed-rank test).Conclusions: Measurement of corneal thickness is useful for assessing the extent of surgical stress following vitrectomy.Keywords: corneal thickness, vitrectomy, MIVS, invasivenessWatanabe AShibata TTakashina HOgawa STsuneoka HDove Medical PressarticleOphthalmologyRE1-994ENClinical Ophthalmology, Vol 2012, Iss default, Pp 1293-1296 (2012)
