Incidence, Pathophysiology, Complications, and Management of Positive Vitreous Pressure During Penetrating Keratoplasty: A Literature Review.

Positive vitreous pressure (PVP) is common during open anterior segment surgery and penetrating keratoplasty (PKP) has a reported incidence rate of 40-50%. Despite adequate perioperative preventive precautions, positive pressure occurs during surgery and optimum management of PVP is required to avoid serious complications. Many pharmacological and mechanical approaches can be employed either preoperatively or intraoperatively to decrease vitreous pressure.

A Comparison Between Cross-Linking Protocols in Patients With Progressive Keratoconus: A Review.

Keratoconus (KC) is a noninflammatory cornea disease leading to progressive thinning, causing it to change from its normal dome shape to a cone shape. One of the novel treatments of KC is corneal collagen cross-linking (CXL). Due to its importance, many studies have been conducted to compare corneal cross-linking protocols; this review article aims to discuss corneal cross-linking and compare its different treatment options, including Dresden, accelerated, and customized protocols in patients with progressive KC and their respective long-term outcomes.

Incidence and outcome of transplantation of fungal-culture-positive donor corneoscleral tissue in optical keratoplasty.

Purpose: This study aims to determine the incidence of fungal-culture-positive corneoscleral donor rim in patients undergoing keratoplasty and evaluate clinical outcomes of eyes that received these contaminated donor tissues.

Methods: Patients who had optical keratoplasty between 2006 and 2016 and were found to have fungal-culture-positive donor rim were included. Microbiological and eye bank records were reviewed to determine the incidence of positive fungal rim cultures.

Serous retinal detachment after panretinal photocoagulation for proliferative diabetic retinopathy: a case report.

Background: Proliferative diabetic retinopathy is a major cause of visual impairment in working-age adults worldwide. Panretinal photocoagulation is a cornerstone in its management; however, it may include a range of side effects and complications, one of these being serous retinal detachment. To the best of our knowledge, this is the first report of the use of intravitreal injection of bevacizumab for serous retinal detachment after panretinal photocoagulation.
