Thickness measurements of donor posterior disks after descemet stripping endothelial keratoplasty with anterior segment optical coherence tomography.

Purpose: To evaluate donor posterior disk thickness measured with anterior segment optical coherence tomography after Descemet stripping endothelial keratoplasty.

Methods: Fifteen patients (17 eyes) after Descemet stripping endothelial keratoplasty, using manually dissected donor posterior disks, were measured with the Visante anterior segment optical coherence tomography (Carl Zeiss Meditec Inc, Dublin, CA). Optical coherence tomography scans were made in a radial pattern, 45 degrees apart, starting in the horizontal axis.

Decreased optical coherence tomography-measured pericentral retinal thickness in patients with diabetes mellitus type 1 with minimal diabetic retinopathy.

Aim: A comparison of retinal thickness (RT) measurements with optical coherence tomography (OCT) in patients with type 1 diabetes mellitus (DM) and no or minimal diabetic retinopathy (DR) versus healthy controls.

Methods: Fifty-three patients with type 1 DM with no or minimal DR underwent full ophthalmic examination, fundus photography and OCT. Mean RT measured by OCT was calculated for the central fovea, the fovea, the pericentral and the peripheral area of the macula, and compared to healthy controls.
