Partial regression of peripapillary myelinated nerve fibers after non-arteritic anterior ischemic optic neuropathy.

A 71-year-old woman presented a non-arteritic anterior ischemic optic neuropathy in an optic nerve with previously registered superonasal peripapillary myelinated nerve fibers.

Changes in eyelid position after glaucoma filtering surgery.

Background: While ptosis is a well-known consequence of glaucoma surgery, some isolated case reports point to the possibility of upper eyelid retraction occurring after glaucoma surgery. This study aims to analyze the occurrence of ptosis and eyelid retraction after glaucoma surgery and to evaluate factors contributing to these palpebral fissure changes.

Methods: Cross-sectional study including 100 eyes of 100 patients that had undergone unilateral glaucoma surgery.

Epidemiology of pseudomembranous conjunctivitis in a tertiary hospital: A 2-year retrospective study.

Purpose: To describe the incidence, duration, and complication rate of patients with a clinical diagnosis of pseudomembranous viral conjunctivitis.

Methods: A retrospective observational study is performed compiling the data of patients diagnosed as pseudomembranous conjunctivitis at the hospital's emergency department from June 2016 to May 2018. Demographic variables, duration of symptoms, and follow-up until resolution of the pseudomembranes and associated complications are collected.

Congenital lacrimal sac diverticulum.

We report the case of a 6-month-old boy with recurrent episodes of acute dacryocystitis from age 3 months to 1 year of age. The cause was determined to be congenital nasolacrimal sac diverticulum, a rare and commonly asymptomatic entity. An isolated diverticulectomy without dacryocystorhinostomy was performed because of lacrimal drainage system patency.
