Do different experimental tasks affect psychophysical measurements of motion perception in autism-spectrum disorder? An analysis.

Clin Optom (Auckl) 2018 12;10:131-143. Epub 2018 Dec 12.

Theoretical and Experimental Epistemology Laboratory, School of Optometry and Vision Science, University of Waterloo, Waterloo, ON, Canada,

There is a rapid increase in the number of individuals with high-functioning autism (HFA). Research on motion perception in HFA has shown deficits in processing motion information at the higher visual cortical areas (V5/middle temporal). Several hypotheses have been put forth to explain these deficits as being due to enhanced processing of small details at the expense of the global picture or as a global integration abnormality.

Therapeutic uses of scleral contact lenses for ocular surface disease: patient selection and special considerations.

Clin Optom (Auckl) 2018 11;10:65-74. Epub 2018 Jul 11.

University of Illinois at Chicago, Chicago, IL, USA.

Scleral lenses are being prescribed for the management of corneal irregularity, uncomplicated refractive error, and ocular surface disease. There are many potential therapeutic uses of scleral lenses in addition to providing similar benefits as corneal gas permeable lenses. Scleral contact lenses are a valuable therapeutic tool for patients with ocular surface disease as these lenses protect the ocular surface, provide continuous corneal hydration while providing optimal visual correction, and are often used in conjunction with other therapies.

Diagnosis and management of blepharitis: an optometrist's perspective.

Clin Optom (Auckl) 2016 8;8:71-78. Epub 2016 Aug 8.

College of Optometry, Adjunct Faculty, University of Missouri-St Louis, St Louis, MO, USA,

Blepharitis is a condition characterized by inflammation of the eyelid margin and is a common cause of discomfort and irritation among people of all ages, ethnicity, and sex. In general, blepharitis is not a sight-threatening condition, but if left untreated has the potential to cause keratopathy, corneal neovascularization and ulceration, and permanent alterations in eyelid morphology. Historically, blepharitis has been categorized according to multiple structural classifications, including anatomic location, duration, and etiology. Read More

Strategies for improving the early diagnosis of keratoconus.

Authors:
Yue Shi

Clin Optom (Auckl) 2016 24;8:13-21. Epub 2016 Feb 24.

Doheny Eye Institute, Department of Ophthalmology, David Geffen School of Medicine, University of California at Los Angeles, Los Angeles, CA, USA,

To diagnose keratoconus at its earliest stage is meaningful in order to avoid refractive surgery in the eye, which may lead to further damage in the abnormal cornea structure and consequently cause iatrogenic ectasia. In this article, the following aspects of detecting earliest stage of keratoconus were reviewed: 1) nomenclature of the earliest forms of keratoconus; 2) diagnosis of keratoconus using curvature-based topography (also known as Placido-based topography, ie, videokeratography) as a traditional method and elevation-based topography as a new method which has gained popularity in recent years; and 3) other methods analyzing keratoconus cornea like corneal biomechanics and wavefront sensing. Elevation-based topography using either Scheimpflug imaging techniques or slit-scanning imaging techniques has shown to be advantageous over the curvature-based topography in detecting keratoconus at its earliest stage.
