Abstract

Purpose: : To evaluate conjunctival grafts with OCT Visante, determining measures and characteristics that could provide useful diagnostic data as well as graft and underlying corneal tissue behavior.

Methods: : Prospective, descriptive study was done between september 2007 to september 2008, we included all adult patients undergoing conjunctival graft surgery with or without tectonic graft for different pathologies. Clinical pictures as well as an OCT visante image of cornea and anterior segment was obtained before the procedure. We analyzed the following variables: corneal thickness from the affected area, anterior chamber depth, conjunctival and corneal graft thickness; and structural characteristics, such as, reflectivity and morphology of the cornea. Follow up visits were at weeks 1, 2, first and third month. A complete exam, slit lamp pictures and OCT visante were done in each visit.

Results: : We included 9 eyes with different pathologies in which conjunctival graft with or without tectonic graft was indicated. We analized the average variation before and after a treatment using Student's t-test. Corneal graft and anterior chamber showed important differnces, although no statistical difference was found for conjunctival graft thickness. Morphological characteristrics varied for each pathology with a predominium of edema and heterogenous reflectivity which are described in detail for each case. Anterior chamber values and characteristics were useful in deciding treatment and prognosis for one pacient.

Conclusions: : OCT Visante is a non invasive study able to obtain images and biometric meassures of the conjunctival grafts, cornea and anterior segment which could be useful in a clinical setting.
