First-order Design of a Reflective Viewfinder for Adaptive Optics Ophthalmoscopy [PDF]

, 2012
Adaptive optics (AO) ophthalmoscopes with small fields of view have limited clinical utility. We propose to address this problem in reflective instruments by incorporating a viewfinder pupil relay designed by considering pupil and image centering and ...

Duration‐Dependent Efficacy and Clinical Safety of Repeated Low‐Level Red‐Light Therapy for Paediatric Myopia: A Systematic Review and Meta‐Analysis

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background Repeated low‐level red‐light (RLRL) therapy is a novel, non‐invasive intervention for controlling paediatric myopia progression. Despite increasing clinical use, questions remain regarding the magnitude, durability, and safety of treatment effects.

Myopia and defocus: the current understanding [PDF]

, 2011
The current theories relating to the development and progression of myopia are related to exposure of the eye to hyperopic defocus. This paper discusses these theories and the large body of recent research investigating the evidence behind them.
