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.
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.
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.
