Purpose: This study aimed to report an experiment designed to determine anatomical changes in porcine corneas following placement of a novel polymer implant into the cornea.
Methods: An ex vivo porcine eye model was used. A novel type I collagen-based vitrigel implant (6 mm in diameter) was shaped with an excimer laser on the posterior surface to create three planoconcave shapes.
Purpose: The purpose of this article is to report a bilateral conjunctivitis case in a patient with confirmed 2019 novel coronavirus disease (COVID-19).
Case Report/observations: A 24-year-old healthy man developed severe conjunctivitis in his right eye, followed by his left eye 4 days after fever and myalgia. He reported yellowish conjunctival discharge, foreign body sensation, redness, and tearing, and those symptoms were resolved in 10 days.
To evaluate the characteristics of Vogt-Koyanagi-Harada (VKH) syndrome in Brazilian children.M Clinical data were obtained from the medical records of six children with VKH disease from March 2014 to June 2018 at the Federal University of São Paulo, Brazil. Six patients met the diagnostic criteria for VKH.

Methods: A cross-sectional, observational study of current practices pertaining to pediatric keratoplasty was performed by designing a 20-question survey focused on preoperative indications, surgical techniques, and postoperative management. This survey was sent electronically to corneal specialists and pediatric ophthalmologists.
Purpose: Zika virus infection is associated with vision-threatening ocular complications including uveitis and outer retinopathy. The aim of this report is to describe a case of an adult patient with serologically confirmed Zika infection who presented with retinal vascular abnormalities that coincided with systemic post-viral neurological manifestations of the disease.
Observations: A 34-year-old white female presented with symptoms of peripheral neuropathy following serologically confirmed Zika virus infection that was acquired in Puerto Rico four months prior to presentation.
Zika virus was considered an innocent pathogen while restricted to the African and Asian population; however, after reaching the Americas in March 2015, it became a global threat. Despite usually causing mild or no symptoms in infected adults, Zika virus displays a different behavior toward fetuses. When infected during gestation, fetuses have their immature neural cells killed by the virus and consequently have devastating findings at birth.

However, successful transplantation can afford a child vision in an otherwise poorly seeing eye. This review will provide an update on recent advances in pediatric keratoplasty.

Background: Calcified band keratopathy is a chronic degenerative disease characterized by the deposition of gray to white opacity in superficial layers of the cornea that typically develops over months or years. It is associated with a variety of conditions, including chronic uveitis.
Purpose: The objective of this study is to assess visual acuity and corneal changes in patients with band keratopathy secondary to uveitis who underwent phototherapeutic keratectomy (PTK).
Purpose: To evaluate topical tacrolimus ointment for treating Thygeson's superficial punctate keratitis (Thygeson SPK).
Design: Retrospective interventional case series.
Methods: setting: Institutional practice.
