Estimations of the Passing Height of Approaching Objects
CONCLUSIONS
Overall, estimates of vertical passing distance were inaccurate particularly at the lower speeds. Underestimates of vertical drop at lower speeds may have resulted from overestimates of ball speeds. At short exposure durations, optical cues associated with ball flight were inadequate for predictions of vertical passing distance at all speeds for the no-experience group and at lower speeds for the experienced group.

Analysis of Optical Coherence Tomography in Acute versus Chronic Central Serous Chorioretinopathy
CONCLUSIONS
The high-reflection band in the outer nuclear layer within the serous neurosensory detachment limited to the macular area was a new finding in CSC patients. This finding can be used as an imaging feature to aid in the diagnosis of CSC. (Source: Optometry and Vision Science)

Digital Eyestrain and the Critical Fusion Frequency
This study sought to determine whether symptoms of digital eyestrain after a sustained computer task are indeed associated with changes in critical fusion frequency.
METHODS
The experiment was performed on 30 young visual-normal subjects. They attended two sessions, during which they undertook a 20-minute reading task. This comprised either reading random words from a tablet computer or a story from a printed children's book. Critical fusion frequency was measured both before and immediately after each of the reading tasks. In addition, the level of digital eyestrain was assessed by subjects completing a questionnai...

Objective Measures of Near Viewing and Light Exposure in Schoolchildren during COVID-19
SIGNIFICANCE
Wearable sensors provide the opportunity for continuous objective measurement of the visual environment with high resolution. Our findings show that absolute and temporal properties of near viewing and time outdoors vary between myopic and nonmyopic schoolchildren, which are important considerations when studying refractive error pathogenesis.
PURPOSE
Numerous behavioral factors, including near work, time outdoors, electronic device use, and sleep, have been linked to myopia. The purpose of this study was to assess behaviors using subjective and objective methods in myopic and nonmyopic schoolchildr...

Topical Review: An Update of Diagnostic and Management Algorithms for Acquired Blepharoptosis
SIGNIFICANCE
Acquired ptosis is a condition of the upper eyelid that has negative cosmetic and functional effects but is likely underdiagnosed and undertreated. Given the evolving understanding of the condition and expanding therapeutic options, this review reappraised published evidence and clinical experience regarding diagnosis and treatment of acquired ptosis.
The authors met over two structured virtual working sessions to review current evidence and develop timely recommendations for acquired ptosis identification, differential diagnosis, characterization, and treatment selection. Diagnostic algorithms, plus ma...

A Randomized Trial of Binocular Dig Rush Game Treatment for Amblyopia in Children Aged 4 to 6 Years
This study aimed to compare change in amblyopic-eye visual acuity (VA) in children aged 4 to 6 years treated with the dichoptic binocular iPad (Apple, Cupertino, CA) game, Dig Rush (not yet commercially available; Ubisoft, Montreal, Canada), plus continued spectacle correction versus continued spectacle correction alone.
METHODS
Children (mean age, 5.7 years) were randomly assigned to home treatment for 8 weeks with the iPad game (prescribed 1 h/d, 5 d/wk [n = 92], or continued spectacle correction alone [n = 90]) in a multicenter randomized clinical trial. Before enrollment, children wearing spectacles were require...

Long-term Effect of Dual-focus Contact Lenses on Myopia Progression in Children: A 6-year Multicenter Clinical Trial
CONCLUSIONS
Dual-focus soft contact lenses continue to slow the progression of myopia in children over a 6-year period revealing an accumulation of treatment effect. Eye growth of the initial control cohort with DFCL was slowed by 71% over the subsequent 3-year treatment period. (Source: Optometry and Vision Science)

Case Report: Multimodal Imaging Features of an ABCA4 Cone Dystrophy
CONCLUSIONS
The identification of an incomplete focal cavitation could alert the clinician to consider early ABCA4 central cone dystrophy. The patient in this case also exhibited reduced vessel density in the foveal area. Both of these characteristics could be important features related to the underlying genetic mutation.

Case Report: Ocular Manifestation of Mantle Cell Lymphoma
CONCLUSIONS
Primary eye care providers should be aware of limitations of orbital imaging during routine positron emission tomography and computed tomography scans in those with MCL, and consultation with neuroradiology for image review may be useful if the clinical findings are suspicious.

Effect of Latanoprostene Bunod on Optic Nerve Head Blood Flow
This study aimed to evaluate the effect of topical latanoprostene bunod on optic nerve blood volume and oxygen saturation in a population of healthy participants.
METHODS
In this prospective double-blind crossover study, 23 healthy participants aged from 21 to 62 years were recruited. Optic nerve head capillary blood volume (ONHvol) and oxygen saturation (ONHSaO2) baselines were measured over a period of 2 hours using multichannel spectroscopic reflectometry and were remeasured after a 7-day once-daily instillation regimen of either latanoprost 0.005% or latanoprostene bunod 0.024%. After a 30-day washout period, pa...
