Juvenile Tree Shrews Do Not Maintain Emmetropia in Narrow-Band Blue Light

Timothy J. Gawne, Alexander H Ward and Thomas T Norton

The authors show that feedback signals from longitudinal chromatic aberrations may be essential to maintain emmetropia in tree shrews that had completed initial emmetropization.

The Relationship between Progression in AL/CR Ratio and Spherical Equivalent Refractive Error in Myopia

T. Monica Jong, Padmaja Sankaridurg, Thomas John Naduvilath, Wayne Li, Mingguang He

In this study the authors assess the validity of determining myopia magnitude or monitoring myopia progression by using the ratio or axial length to corneal radius of curvature. They found that this anatomical relationship behaves differently for low and high myopia.

Tear Lactoferrin and Features of Ocular Allergy in Different Severities of Meibomian Gland Dysfunction

Cecilia Chao, Louis Tong

Meibomian gland dysfunction, but not atrophy, may be associated with increased ocular surface inflammation and reduced tear lactoferrin production.

Development of Silicone Hydrogel Antimicrobial Contact Lenses with Mel4 Peptide Coating

Debarun Dutta, Bjorn Kamphuis, Berkay Ozcelik, Helmut Thissen, Rasim Pinarbasi, Naresh Kumar and Mark DP Willcox

The authors have developed Mel4, an antimicrobial contact lens coating, which may reduce contact lens related infection and inflammatory events.

Shelf-Life and Efficacy of Diagnostic Eye Drops

Jean-Marie Hanssens, Carolina Quintana-Giraldo, Sandrine Jacques, Nohade El-Zoghbi, Vanessa Lampasona, Camille Langevin, Jean-Francois Bouchard

The authors of this study found that diagnostic eye drops maybe used for up to 7 months instead of the recommended 28-days and found low contamination with similar efficacy in a clinical setting.

iPhone-based Pupillometry: A Novel Approach for Assessing the Pupillary Light Reflex

J. Jason McAnany, Brandon M Smith, Amy Garland, Steven L Kagen

Our authors describe a smart phone-based method for measurement of the pupillary light reflex. This method showed excellent agreement with infrared video-based pupil measurements.

Neutralizing Peripheral Refraction Eliminates Refractive Scotomata in Tilted Disk Syndrome

Jack Phu, Henrietta Wang, Sephora Miao, Lydia Zhou, Sieu Khuu, Michael Kalloniatis

Tilted optic discs can be associated with visual field defects. In this study our authors show that some of the visual field defect could be mitigated by compensating for peripheral retinal defocus in the tilted disc region.

Case Report: Importance of B-scan Ultrasonography for the Detection of Choroidal Melanoma

Margaret A. Wilczek, Aaron Samuel Gold, Fiona J. Ehlies, Timothy G. Murray

Ultrasonography is commonly used to assess eyes where no clear view of the fundus is possible. This case demonstrates the use of ultrasound to detect a choroidal melanoma.
