Performance of the Plusoptix A09 photoscreener in detecting amblyopia risk factors in Chinese children attending an eye clinic.

Purpose: To assess the accuracy of the Plusoptix A09 photoscreener in detecting amblyopia risk factors in children and determine referral criteria when using Plusoptix A09 for a large-scale vision screening.

Methods: Pediatric patients attending our eye clinic underwent a comprehensive ophthalmic examination that included photorefraction, orthoptic examination, anterior segment assessment, fundus examination and cycloplegic retinoscopy. The measurements were collected for statistical analyses.

[Antiproliferative effect of sustained drug delivery system of all-trans retinoic acid implant into rabbit's vitreous cavity for treatment of proliferative vitreoretinopathy].

Objective: To investigate the antiproliferative effect of different concentration of all-trans retinoic acid (atRA) in a drug delivery system (DDS) in an experimental proliferative vitreoretinopathy (PVR) model.

Methods: The PVR animal model was induced by central vitrectomy and homologous fibroblasts injected at the same time in pigmented rabbits. Fifty rabbits underwent the surgery.
