Effect of Continuous Positive Airway Pressure Treatment on the Arteriole-to-Venule Ratio in Patients With Nonproliferative Diabetic Retinopathy and Obstructive Sleep Apnea: A Randomized Trial.

Background And Objective: This study aimed to assess the effect of continuous positive airway pressure (CPAP) on the arteriolar-to-venular ratio (AVR) in patients with diabetic retinopathy (DR) and obstructive sleep apnea (OSA).

Patients And Methods: A prospective, randomized, unblinded, and controlled clinical trial with parallel groups was performed. From a base of 138 patients, 83 were randomized to either CPAP or control.

A Pilot Study of a Panel of Ocular Inflammation Biomarkers in Patients with Primary Sjögren's Syndrome.

Ocular diseases have a strong impact on individuals, the effects of which extend from milder visual impairment to blindness. Due to this and to their prevalence, these conditions constitute important health, social and economic challenges. Thus, improvements in their early detection and diagnosis will help dampen the impact of these conditions, both on patients and on healthcare systems alike.

Contralateral orbicularis oculi muscle transposition in facial paralysis: functional, aesthetic and electromyographic outcomes. A case report and literature update.

Purpose: Many surgical approaches have been described for achieving satisfactory functionality in patients with facial paralysis, to ensure the protection of the cornea and the highest degree of physiological blinking. Out of all those available, dynamic techniques are indicated when motion recovery and synchrony are the goals pursued. transposition (OOT) allows a genuine restoration of blinking by means of contralateral reinnervation, with minimal insult for the donor site.
