Metabolic monitoring of transcorneal electrical stimulation in retinitis pigmentosa.

Purpose: Transcorneal electrical stimulation (TES) is a novel treatment approach for patients with retinitis pigmentosa (RP). With progression of RP, loss of photoreceptors leads to less oxygen consumption and lower demand in the retina. Retinal oximetry (RO), as a non-invasive method to analyse oxygen saturation in retinal vessels, promises to be a useful therapy monitoring tool.

Muscle Relaxants as a Risk Factor for Vis-à-tergo During Penetrating Keratoplasty: A Prospective Interventional Study.

Introduction: This study aimed to investigate the influence of three muscle relaxants on intraocular pressure (IOP), ocular pulse amplitude (OPA), and vis-à-tergo (VAT) in patients undergoing penetrating keratoplasty (PKP) under general anesthesia.

Methods: Ninety-five patients undergoing PKP were included in this prospective single-center interventional study. IOP and OPA were measured with a dynamic contour tonometer before and 5 min after onset of general anesthesia.
