IN THIS ISSUE:

• Increasing Letter Chart Contrast Sensitivity Reliability

Figure
Figure

The importance of the use of similarly identifiable chart letters is known for clinical tests. Our authors suggest that using only high-frequency components in letters for chart clinical research design reduces interletter contrast sensitivity differences. (p. 1125)

• Smart Phone Autorefractor

Figure
Figure

Our authors found that a portable Hartmann-Shack wavefront aberrometer attached to a smart phone (SVOne) enabled an objective assessment of mean spherical refractive error for screening purposes, comparable to retinoscopy, subjective refraction, and two other autorefractors. (p. 1133)

• Portable Autorefractor Prototype

Figure
Figure

In their clinical evaluation of their novel wavefront sensing portable autorefractor (“Quicksee”) against a commercial autorefractor (Grand Seiko WR-5100K), the authors found equivalence in measuring spherical and astigmatic refractive errors. The potential manufacturing cost is reported to be low. (p. 1140)

• Accommodation Reduced in Vitrectomy

Figure
Figure

Uneventful monocular pars plana vitrectomy in prepresbyopia reduced accommodation at 12 weeks after vitrectomy (compared with the other eye) without observable cataract progression. (p. 1148)

• Replacement of Lenses Exposed to High UV Radiation?

Figure
Figure

Our authors consider their study to be the first demonstration that UV radiation of CR39, polyurethane, and polycarbonate lenses with various hard and antireflection coatings significantly weakened the lenses in ballistic impact tests. (p. 1154)

• Lens Implant Changes Pupil Size

Figure
Figure

The anterior vault design of an implantable collamer lens for high myopia affects pupil dynamics. Postoperative pupil diameters were smaller, perhaps related to mechanical contact between the implantable collamer lens and the posterior iris surface. (p. 1161)

• Distortion Correction for Corneal Tomography

Figure
Figure

Unfortunately, commercially available optical coherence tomography systems (e.g., Visante) suffer from geometric and optical distortions resulting in inaccurate measurement of anterior segment parameters according to our authors. They develop distortion corrections that effectively address this problem for Visante images. (p. 1170)

• IOP Changes with Health Characteristics

Figure
Figure

In an impressively large (>150,000 nonglaucoma participants in their twenties through their fifties) Korean study, our authors show that male sex, high systolic blood pressure, diabetic parameters, factors related to obesity, and current smoking status were significantly correlated with increased intraocular pressure. (p. 1182)

• Toward Evidence-Based Dry Eye Management

Figure
Figure

Our authors provide an evidence-based review for contemporary clinical diagnosis and care of dry eye. (p. 1189)

• Common Clinical Features Hide Rare Condition

Figure
Figure

The authors describe an unusual presentation of Foster Kennedy syndrome (unilateral optic nerve atrophy with optic nerve edema in the other eye) with optic nerve atrophy and hemiretinal vein occlusion where a comprehensive examination and imaging revealed the diagnosis. (p. e425)

• Confocal Microscopy in Endotheliitis

Figure
Figure

The authors describe an adult case of endotheliitis treated and resolved on biomicroscopy where confocal microscopy detected subclinical inflammation—a surprising finding. (p. e431)

• Atypical Morning Glory Syndrome

Figure
Figure

In a 6-year-old child, despite normal visual function, neuroimaging revealed ipsilateral carotid and middle cerebral vascular narrowing without associated collateral vessels or cerebral ischemia. The case illustrates the wide phenotype and variability of morning glory syndrome. (p. e437)
