Rheological Behavior Patterns in Artificial Tears
CONCLUSIONS
The viscosity of artificial tears always depends on the shear rate. It is possible to find two patterns simultaneously depending on the shear rate. These rheological patterns could serve to optimize the treatment with lubricants for different conditions of the ocular surface. In vivo studies are necessary to evaluate the clinical significance of these findings. (Source: Optometry and Vision Science)

Compliance versus Risk Awareness with Contact Lens Storage Case Hygiene and Replacement
This study aimed to determine level of compliance with common practices regarding CL storage case hygiene and replacement, type of information provided by practitioners, and risk perception.
METHODS
An ad hoc self-reported survey was used to collect demographic and CL wear details, compliance with storage case care, type of received information, and risk perception (in a 1-to-5 scale). Inferential statistics explored the relationship of demographic details and type of received information with compliance and risk perception.
RESULTS
Nondaily disposable wearing participants returned 299 completed surveys, with...

Comparison of Epithelial Thickness Mapping in Normal Corneas with Different Types of Astigmatism
This study aimed to compare corneal epithelial thickness along different meridians in normal eyes with different types of corneal astigmatism.
METHODS
In this cross-sectional study, corneal topography and epithelial thickness mapping by anterior segment optical coherence tomography was performed for 154 normal eyes. Corneal astigmatism was classified based on the orientation of the steepest corneal meridian (with-the-rule [WTR], against-the-rule [ATR], and oblique) and the amount (low, moderate, and high). On a 9-mm epithelial thickness map, the thickness along the horizontal (180°), vertical (90°), and diagonal (...

Effect of Combining 0.01% Atropine with Soft Multifocal Contact Lenses on Myopia Progression in Children
CONCLUSIONS
Adding 0.01% atropine to SMCLs with +2.50-D add power failed to demonstrate better myopia control than SMCLs alone. (Source: Optometry and Vision Science)

The Limited Value of Prior Change in Predicting Future Progression of Juvenile-onset Myopia
CONCLUSIONS
Young, more myopic Asian American children in the Collaborative Longitudinal Evaluation of Ethnicity and Refractive Error Study were the most likely to progress rapidly. Clinical trials should expect average progression rates that reflect sample demographics and may have difficulty recruiting generalizable samples that progress faster than that average. Knowing progression or elongation history does not seem to help the clinical decision regarding initiating myopia control. (Source: Optometry and Vision Science)

Clinical Report: Experiences of a Driver with Vision Impairment when Using a Tesla Car
CONCLUSIONS
This clinical report demonstrates how assisted and semiautonomous driving systems in a Tesla car were used to support daily driving by a driver with vision impairment. Codriving with these systems allows him to confidently drive more often and to avoid less situations than he used to. (Source: Optometry and Vision Science)

Case Report: Visual Snow Syndrome after Repetitive Mild Traumatic Brain Injury
CONCLUSIONS
Although rare, visual snow syndrome should be considered in all patients reporting continuous pixelations in their vision for more than 3 months, especially when accompanied by at least two of the following: photosensitivity, palinopsia, enhanced entopic phenomena, or nyctalopia. The pathophysiology is still unclear at this point, with evidence suggesting a link to the secondary visual cortex, specifically the lingual gyrus. More studies are needed to determine the exact cause, especially studies that separate visual snow syndrome patients with and without comorbid migraine. Because the pathophysiology is u...

Case Report: Occult Macular Dystrophy
CONCLUSIONS
Reduced visual acuity with a normal clinical examination result is commonly encountered in patients with occult macular dystrophy. Therefore, clinicians must be aware of occult macular dystrophy and order appropriate testing to accurately identify cases of occult macular dystrophy. Without thorough evaluation, patients may be easily misdiagnosed with other etiologies of vision loss. (Source: Optometry and Vision Science)

Case Report: Intracorneal Hemorrhages Seen with Scleral Contact Lens Wear and Netarsudil Therapy
CONCLUSIONS
There are few reports of intracorneal hemorrhages associated with scleral contact lens use and even fewer associated with the use of netarsudil. This case proposes several possible causes of the intracorneal hemorrhages, including topical rho-associated kinase inhibitors, contact lens wear, and trauma. Further studies are needed to determine if netarsudil is associated with intracorneal hemorrhages, to understand the sequelae of intracorneal hemorrhages in netarsudil therapy, and to recommend management when intracorneal hemorrhages manifest with netarsudil use.

Technical Report: Reducing Lens Fogging Associated with Patient Mask Wearing with Heated Diagnostic Fundoscopy Lenses
This study quantified the degree of lens fogging in mask-wearing subjects using ImageJ to measure lens surface area fogged in slit-lamp photographs of 90 D lenses before and after the use of a lens warmer. We investigated the clinical relevance of diagnostic lens fogging via a survey study of eye care providers. Subjects rated on a Likert scale their experience with diagnostic lens fogging during retinal examination in mask-wearing patients with and without the use of a lens warming device.
RESULTS
For mask-wearing subjects, the percentage of fogged lens area in a 90 D lens averaged 32.5% using an unheated lens and ...

Case Series: Tattoo-associated Uveitis
CONCLUSIONS
Simultaneous tattoo granuloma and uveitis is well supported by literature evidence. It is suspected that both patients either had a localized sarcoidosis reaction or had tattoo-associated uveitis due to a delayed-type hypersensitivity reaction caused by an unknown antigen in the tattoo ink.
