Abstract

BackgroundTo study the effect of retinal- vitreoretinal surgeries on corneal elevations.

MethodsPatients who underwent retinal- vitreoretinal surgeries were divided into 3 groups. Scleral buckling was performed in 11 eyes Group 1. In 8 25% eyes, vitreoretinal surgery was performed along with scleral buckling Group 2. In 12 eyes, pars plana vitrectomy was performed for vitreous hemorrhage Group 3. An encircling element was used in all the eyes. The parameters evaluated were best-corrected visual acuity BCVA, change in axial length, and corneal topographic changes on Orbscan topography system II, preoperative and at 12 weeks following surgery.

ResultsThere was a statistically significant increase in anterior corneal elevation in all the three groups after surgery p = 0.003, p = 0.008 and p = 0.003 respectively. The increase in posterior corneal elevation was highly significant in all the three groups after surgery p = 0.0000, p = 0.0001 and p = 0.0001 respectively. The increase in the posterior corneal elevation was more than the increase in the anterior elevation and was significant statistically in all the three groups group I: p = 0.02; group II: p = 0.01; group III: p = 0.008.

ConclusionsRetinal- vitreoretinal surgeries cause a significant increase in the corneal elevations and have a greater effect on the posterior corneal surface.
