Venous-air embolism during vitrectomy for endoresection of choroidal melanoma: Case report.

Introduction: The purpose of this study is to report a case of venous-air embolism during a vitrectomy for endoresection of choroidal melanoma.

Case Description: A 31-year-old man went to the clinic because of photopsias and vision loss in his right eye. On fundoscopy of the right eye, a choroidal mass with an associated retinal detachment was found near the inferotemporal vascular arcade.

Retinopathy of prematurity: incidence report of outliers based on international screening guidelines.

Aim: The objective of this study is to report the incidence of retinopathy of prematurity (ROP) outliers that fall outside the screening guidelines of the American Academy of Ophthalmology (AAO) in our country.

Methods: A retrospective review of 503 records of newborns evaluated in our institution between January 2011 and March 2017. We analyzed the data by subgroups based on gestational age (GA), birth weight (BW) and stage, focusing on the outliers that don't meet the criteria of the screening AAO guidelines (GA ≤ 30 weeks, BW ≤ 1500 g).

Multimodal imaging in choroidal osteoma.

Purpose: To describe characteristics of choroidal osteomas (CO), using ocular ultrasound, fluorescein angiography, ultra-widefield retinal imaging, ultra-widefield autofluorescence, optical coherence tomography, enhanced-depth-imaging OCT, and OCT angiography (OCT-A).

Methods: Retrospective, observational case series study. Clinical records from patients with diagnosis of CO who underwent complete imaging evaluation were analyzed.
