Perception of #TheDress in childhood is influenced by age and green-leaf preference.

The perception of the ambiguous image of #TheDress may be influenced by optical factors, such as macular pigments. Their accumulation during childhood could increase with age and the ingestion of carotenoid-containing foods. The purpose of this study was to investigate whether the visual perception of the dress in children would differ based on age and carotenoid preference.

Importance of multimodal imaging diagnostics in acute angle closure glaucoma: Case report.

To describe the natural history and management of an acute angle closure secondary to choroidal melanoma. A 70-year-old female presented with pain, elevated intraocular pressure, mature cataract, and angle closure in right eye. With further studies she was found to have a choroidal melanoma causing the acute angle closure.

Ultrasound-Guided Pars Plana Vitrectomy.

Purpose: To assess the feasibility of a novel surgical technique that combines B-scan ultrasound with modern vitrectomy techniques.

Methods: Patients with a clinical diagnosis of infectious keratitis endophthalmitis, which were scheduled for pars plana vitrectomy and ruled out as candidates for transient keratoprosthesis, were enrolled. The ultrasound probe was placed over the eye to use the images to witness the vitreous movement around the cutter and to establish its position in relation to the retinal wall.

Primary Cancer Sites and Clinical Features of Choroidal Metastasis in Mexican Patients.

Purpose: To describe the primary cancer sites and clinical features of choroidal metastasis in Mexican patients.

Methods: This was a retrospective, observational, and multi-center study. Data were recollected from 6 ophthalmological hospitals in Mexico from patients with choroidal metastasis diagnosed from 2000 to 2018.

A Proposed Method to Quantify Vitreous Hemorrhage by Ultrasound.

Purpose: To propose a method for quantification of vitreous hemorrhages (VH) termed minimum image gain (MIG). Therefore, to obtain MIG measurements in patients with VH and to compare them to normal controls; to compare results between graders; and to obtain and compare MIG from two different ultrasound systems.

Methods: Retrospective and cross-sectional, observational, and comparative study performed in two parts: Part 1) Retrospective comparison of MIG in VH vs controls by two experienced graders, with intra/inter-observer variability: MIG technique is described.
