Accommodating IOLs Differ for Myopes

The authors use MRI, OCT, ultrasound and interferometry to quantify the dimensions of the human eye in vivo, and explore differences with accommodation, age and refractive error. This is the first evidence for why accommodating IOLs may have different effects in myopes than in hyperopes.
Cycloplegia Produces Corneal Flattening in Myopes

Cycloplegia leads to flattening of the cornea and deepening of the anterior chamber in adult myopes, particularly the posterior curvature. Recognizing these changes allows more accurate phakic/functional IOL selection and improved refractive results.
Genetic Basis For Very Short Hyperopic Eyes

The authors study used whole exome and Sanger sequencing analyzed Chinese probands with high hyperopia. Three potential pathogenic compound heterozygous mutations were detected in three of the 46 probands. This may be the first report of these mutations in a Chinese cohort.
Binocular Status and Accommodation Impact on Myopia Children

As part of an ongoing clinical trial using up to 3D plus addition lenses, the authors seek optimal binocular balance on myopia control by comparing accommodative response, phoria, and fusional amplitudes at 33 cm  before and after 6 minutes of adaptation.

Is Lipid Uptake on Contact Lenses Increasing Discomfort?

By examining the in vitro uptake of cholesterol on a variety of daily disposable lens materials, our authors show that cholesterol uptake is greater on some silicone hydrogel materials. They suggest patients with an oilier tear film could potentially have an issue with such materials and this could decrease comfort.
Corneal Inflammatory Events in Contact Lens Wearers

In an attempt to identify the contact lens related modifiable and non-modifiable factors associated with corneal inflammatory events (CIE) our authors studied about 80 CL wearers with CIE and 80 controls. Age, and interaction between disinfectant and wearing schedule were significant determinants of CIE in the 18 -36 year old university eye care center participants.

Corneal Edema and Non-Contact and Contact Tonometry

The IOP differences between before and after post cataract surgery was measured by both non-contact and contact tonometry. The tonometry increase after phacoemulsification surgery appears related to increased edema with corneal thickening.
Intermittent Exotropia and Birth Hypoxia

In a relatively large Chinese pre-school population aged 3-6yrs (n = 5831), intermittent exotropia (IXT) of 10 prism diopters or more had a prevalence of about 1 in 30 and was strongly associated with hypoxia at birth.

Upper Airway Obstruction and RNLF Thinning

Upper airway obstructions and sleep apnea, relatively common (upwards of 3%) in young children and often the result of adenotonsillar hypertrophy, were associated with reversible thinning of the retinal nerve fiber layer (RNLF) - a novel and important finding for the literature. All 42 children in the study had tonsillectomies and subsequently had thickening of the RNLF for the group.
Vision Detection of Early AMD?

The authors use what they call a functional visual acuity (FVA) system, with 2-second monitor exposure of Landolt rings, to report early changes in unilateral age-related macular degeneration (AMD) attributable to retinal changes revealed by optical coherence tomography.
Low Vision Provision Nation-Wide

The author proposes a 3-tier model whereby all patients seen by optometrists in Canada could ultimately receive appropriate low vision care.

Variations in Color of Mobile Devices

The authors call for a standardization of color specifications for mobile devices, especially if they are to be used for vision testing. The authors note the assumptions on color additivity can lead to egregious errors in vision testing.

World Renowned Vision Scientist Traces His Optometric Path

After entering the Optometry program at Sydney Technical College in 1940, Gerald Westheimer reveals a very interesting journey in becoming a leading international optometric scientist, a faculty member in three USA optometry schools and finally a long research career in vision science and neurophysiology at UC Berkeley.

A Rare Look at APMPPE

Acute Posterior Multifocal Placoid Pigment Epitheliopathy (APMPPE) is a rare inflammatory condition with acute bilateral visual loss due to multiple cream colored Retinal Pigment Epithelium (RPE) lesions. The possible mechanism is explained in this clinical case, as the presence of papillitis and serous retinal detachments was an intermediate between APMPPE and Harada's disease.

Atypical Exophytic Retinal Capillary Hemangioma (RCH)

Our authors present a clinical case illustrating an atypical exophytic peripheral RCH, rarely reported in the literature. The utilization of various diagnostic modalities was highly effective in the diagnosis of this rare tumor.
