Purpose: The SVOne is a portable Hartmann-Shack wavefront aberrometer that can be attached to a smartphone to determine the refractive error of the eye objectively. The aim of the present study was to compare the findings of the SVOne with retinoscopy, subjective refraction, and two commercially available autorefractors (Topcon KR-1W and Righton Retinomax-3).

Conclusions: The results indicate that the SVOne handheld aberrometer provides measurements of refractive error in normal, young individuals that are not significantly different from other subjective and objective procedures. This instrument is valuable for vision screenings, as well as examinations taking place outside the clinical office. It may also serve as an adjunct in the standard optometric examination.

Purpose

Noninfectious uveitis results in vision loss and ocular complications without adequate treatment. We compared the risk of developing ocular complications between patients with noninfectious intermediate uveitis, posterior uveitis, or panuveitis (NIIPPU) and matched controls.

Large submacular hemorrhage, an uncommon manifestation of neovascular age-related macular degeneration, may also occur with idiopathic polypoidal choroidal vasculopathy. Submacular hemorrhage damages photoreceptors owing to iron toxicity, fibrin meshwork contraction, and reduced nutrient flux, with subsequent macular scarring. Clinical and experimental studies support prompt treatment, as tissue damage can occur within 24 hours. Without treatment the natural history is poor, with a mean final visual acuity (VA) of 20/1600. Reported treatments include retinal pigment epithelial patch, macular translocation, pneumatic displacement, intravitreal or subretinal tissue plasminogen activator, intravitreal anti-vascular endothelial growth factor (VEGF) drugs, and combinations thereof. In the absence of comparative studies, we combined eligible studies to assess the VA change before and after each treatment option.

Although there is evidence for specialization in the human brain for processing biological motion per se, few studies have directly examined the specialization of form processing in biological motion perception. The current study was designed to systematically compare form processing in perception of biological (human walkers) to nonbiological (rotating squares) stimuli. Dynamic form-based stimuli were constructed with conflicting form cues (position and orientation), such that the objects were perceived to be moving ambiguously in two directions at once. In Experiment 1, we used the classification image technique to examine how local form cues are integrated across space and time in a bottom-up manner. By comparing with a Bayesian observer model that embodies generic principles of form analysis (e.g., template matching) and integrates form information according to cue reliability,

Research from JAMA Ophthalmology — Global Survey of Corneal Transplantation and Eye Banking

Importance  Corneal transplantation restores visual function when visual impairment caused by a corneal disease becomes too severe. It is considered the world’s most frequent type of transplantation, but, to our knowledge, there are no exhaustive data allowing measurement of supply and demand, although such data are essential in defining local, national, and global strategies to fight corneal blindness.

To evaluate the association between platelet function and disc hemorrhage in patients with normal-tension glaucoma.

Design

Prospective, cross-sectional study.

Methods

Study involved a total of 315 subjects, including patients with normal-tension glaucoma and disc hemorrhage (n = 120), patients with normal-tension glaucoma without disc hemorrhage (n = 75), and healthy individuals (control group, n = 120). A detailed eye examination including visual field testing, color disc photography, optical coherence tomography scanning, and measurement of collagen/epinephrine closure time using a platelet function analyzer were performed for all subjects.

Primate foveas have several features that are relatively unique. One is the paucity of anterior vasculature in an area in which photoreceptor density, and hence metabolic activity, is strongly peaking (declining in number exponentially as one moves from the foveola). This area is called the foveal avascular zone (FAZ). Another is the dramatic accumulation of dietary carotenoids, specifically lutein and zeaxanthin, also strongly peaking in the very center of the fovea (called macular pigment [MP]). This accumulation can be as high as 1000 times the amount in serum for some individuals (the highest accumulation of carotenoids in the body) or nearly indetectable for others.
