Conjunctival Myxoma: High-Resolution Optical Coherence Tomography Findings of a Rare Tumor.

Purpose: The purpose of this study was to describe 2 cases of biopsy-proven conjunctival myxomas and present their optical signs on high-resolution optical coherence tomography (HR-OCT) with clinical and histopathological correlations.

Methods: Two middle-aged female patients with a clinical diagnosis of conjunctival cysts were referred for surgical treatment. Clinical assessment, photographs, ultrasound biomicroscopy, and HR-OCT images were obtained.

Polymicrobial Keratitis: Risk Factors, Clinical Characteristics, Bacterial Profile, and Antimicrobial Resistance.

Objective: To describe clinical characteristics, complications, and the most prevalent microorganisms causing polymicrobial keratitis and their antibiotic sensitivities.

Methods: A cross-sectional study including a consecutive analysis of patient's records with a diagnosis of bacterial keratitis with a positive culture and antibiogram report were included. Patients were grouped into those having monomicrobial and polymicrobial infection.

In Vivo Confocal Microscopy Findings in Bowman Layer Transplantation.

Purpose: To report the in vivo confocal microscopy (IVCM) findings of a case who underwent femtosecond laser-assisted Bowman layer transplantation (BLT).

Methods: This is a case report.

Results: In a 25-year-old man with previous diagnosis of keratoconus in whom a BLT was performed using the femtosecond laser-assisted technique, IVCM (Confoscan 4; Fortune Technologies, Vigonza, Italy) was performed 3 months after surgery, obtaining a sequence of 4 digitalized images of the total thickness of the cornea, from the epithelium to the endothelium, and then backward.

Whole exome profiling and mutational analysis of Ocular Surface Squamous Neoplasia.

Purpose: To determine genetic mutational profiles in patients with Ocular Surface Squamous Neoplasia (OSSN) using whole exome sequencing.

Methods: Prospective, case-series study. Patient recruitment was conducted in a single tertiary referral center from April to September 2017.

Bowman layer transplantation using a femtosecond laser.

We describe a variation of the original manual Bowman layer transplantation technique. After the isolation of the graft, a stromal pocket is created using a femtosecond laser. With the use of this technology, which entails preservation of the conjunctiva and the non-use of sutures, we avoid the scleral approach.

Optic Neuropathy Secondary to Polyarteritis Nodosa, Case Report, and Diagnostic Challenges.

Purpose: To describe a case of optic neuropathy as a primary manifestation of polyarteritis nodosa (PAN) and discuss diagnostic challenges.

Methods: Case report.

Results: A 41-year-old Hispanic man presented with a 2-day history of reduced visual acuity in his left eye.
