Validation of a New Software Application for Tear Breakup Measurement
SIGNIFICANCE
Tear film instability has been recognized as one key mechanism on dry eye disease. There is a need for new instruments, methods, or protocols to improve the repeatability and reproducibility of the tear film stability to facilitate its clinical evaluation use as a rapid and reliable primary diagnostic test.
PURPOSE
The present pilot study aimed to validate a method to automatically measure the tear film breakup time (BUT).
METHODS
A total of 264 videos of BUT were randomly selected among the clinical history of subjects attending the optometry clinic. Videos were stored in a backup server thr...

Differences in Image Quality after Three Laser Keratorefractive Procedures for Myopia
This study aimed to compare longitudinal changes in higher-order wavefront aberrations and image quality before and after bilateral PRK, FS-LASIK, and SMILE refractive procedures for correcting myopia.
METHODS
Wavefront aberrations and image quality of both the eyes of 106 subjects (n = 40 for FS-LASIK and SMILE and n = 26 for PRK) were determined pre-operatively and at 1-week, 1-month, 3-month, and 6-month post-operative intervals using computational through-focus analysis for a 6-mm pupil diameter. Image quality was quantified in terms of its peak value and its interocular difference, residual defocus that was nee...

Vision, Driving Exposure, and Collisions in Bioptic Drivers
CONCLUSIONS
Visual acuity, visual field, and contrast sensitivity were associated with driving exposure in bioptic drivers (with drivers with poorer vision reporting lower annual mileage), and poorer visual acuity and visual field were associated with more collisions. The per-mile collision rate for bioptic drivers was within the range of that previously reported for fully sighted drivers, although higher than would be expected for fully sighted drivers of similar age distribution.

Detection of Significant Hyperopia in Preschool Children Using Two Automated Vision Screeners
This study aimed to compare the sensitivity and specificity of two automated screening devices to identify preschool children with moderate to high hyperopia.
METHODS
Children in the Vision in Preschoolers (VIP) study were screened with the Retinomax Autorefractor (Nikon, Inc., Melville, NY) and Plusoptix Power Refractor II (Plusoptix, Nuremberg, Germany) and examined by masked eye care professionals to detect the targeted conditions of amblyopia, strabismus, or significant refractive error, and reduced visual acuity. Significant hyperopia (American Association for Pediatric Ophthalmology and Strabismus definition o...

Topical Review: Studies of Ocular Function and Disease Using Hyperspectral Imaging
SIGNIFICANCE
Advances in imaging technology over the last two decades have produced significant innovations in medical imaging. Hyperspectral imaging (HSI) is one of these innovations, enabling powerful new imaging tools for clinical use and greater understanding of tissue optical properties and mechanisms underlying eye disease.
Hyperspectral imaging is an important and rapidly growing area in medical imaging, making possible the concurrent collection of spectroscopic and spatial information that is usually obtained from separate optical recordings. In this review, we describe several mainstream techniques used in ...

Effect of Autologous Serum Eye Drops on Corneal Haze after Corneal Cross-linking
This study aimed to compare the effect of autologous serum tears versus preservative-free artificial tears on the prevention and resolution of post–cross-linking corneal haze.
METHODS
A retrospective cohort study was conducted in a sample population from one surgeon at a tertiary eye center from 2016 to 2019. Seventy-six eyes of consecutive patients who underwent cross-linking were included. Records were reviewed for corneal Scheimpflug densitometry values and maximum keratometry, epithelial healing time, and the use of either autologous serum tears or preservative-free artificial tears. Corneal densitometry value...

Case Report: Erdafitinib-induced Central Serous Chorioretinopathy
CONCLUSIONS
Erdafitinib, a potent tyrosine kinase receptor inhibitor of fibroblast growth factor receptors 1 to 4, demonstrates antitumor activity in advanced urothelial carcinoma with fibroblast growth factor receptor mutations with a response rate of approximately 40%. However, central serous chorioretinopathy develops in 25% of patients treated with a daily 8-mg dose of erdafitinib. Although most mild to moderate erdafitinib-induced central serous chorioretinopathies resolve with dose interruption or reduction, occasionally discontinuation of the medication is necessary. Therefore, careful coordination with oncologi...

Case Report: Longitudinal Effect of Progressive Epiretinal Membrane on the Retinal Nerve Fiber Layer
CONCLUSIONS
Both macular and RNFL OCT allow us to observe morphologic changes to the retina caused by epiretinal membrane. Other authors have described this phenomenon, but this case demonstrates the continual change over time, suggestive of a dynamic process that requires continuous awareness and monitoring. Clinicians should be especially aware of this phenomenon when a patient is also suspicious of glaucoma. These RNFL changes can make it more problematic to rely on the OCT GPA to determine early progressive glaucomatous changes to the RNFL. (Source: Optometry and Vision Science)

Case Report: Swept-source Optical Coherence Tomography and Angiography Findings in Lipemia Retinalis
CONCLUSIONS
Swept-source OCT and OCT-A were beneficial in assessing lipemia retinalis noninvasively and monitoring choroidal and retinal vascular changes. Lipemia retinalis signs regressed initially in the posterior pole, choroidal anomalies were first to resolve, and clinical normalization preceded tomographic resolution.

Effect of a Novel Omega-3 and Omega-6 Fatty Acid Supplement on Dry Eye Disease: A 3-month Randomized Controlled Trial
This study aimed to determine the effect of daily intake of a novel combination of essential fatty acids on signs and symptoms of DED.
METHODS
Participants with moderate to severe DED were enrolled in a prospective, randomized, double-masked parallel group study. Participants ingested either the treatment supplement containing omega-3 and omega-6 fatty acids (1200 mg eicosapentaenoic acid, 300 mg docosahexaenoic acid, 150 mg γ-linoleic acid) or the placebo (coconut and olive oil) daily for 3 months. To determine compliance, Omega-3 Index blood tests were conducted. At baseline and at 1 and 3 months, the following a...
