SIGNIFICANCE: Existing patient-reported outcome instruments in refractive error are paper-based questionnaires. They are not comprehensive and psychometrically robust. This study has identified the content of the refractive error-specific item banks that aim to provide comprehensive and scientific measurement of refractive error-specific quality of life. PURPOSE: The purpose of this study was to identify minimally representative, optimally informative, and efficient sets of items for measuring quality of life in people with refractive error METHODS: First, items were identified from existing patient-reported outcome instruments...

SIGNIFICANCE: Before the appearance of evident keratoconus, corneal biomechanical changes may be detectable. Here, these properties are analyzed to detect any difference that could help in the early recognition of keratoconus to allow patients to benefit from early treatments and to avoid refractive procedures in these corneas. PURPOSE: The purpose of this study was to compare corneal biomechanical characteristics as determined by Corvis Scheimpflug Technology tonometry between normal eyes and asymmetric keratoconic eyes...

Hyung Bin Lim, Woo Hyuk Lee, Young Joon Jo, Jung Yeul Kim
SIGNIFICANCE: The interocular difference in the ganglion cell-inner plexiform layer thickness showed a significant correlation with the diabetic retinopathy (DR) severity. PURPOSE: The purpose of this study was to analyze the interocular differences in the foveal, retinal nerve fiber layer (RNFL), and ganglion cell-inner plexiform layer (GC-IPL) thickness of DR patients using spectral-domain optical coherence tomography. METHODS: A total of 508 eyes from 254 patients with different severities of DR and 184 eyes from 92 control subjects were included...

Anna B Webster, Georgia M Lyon, Kathryn A Blowers, Gillian N Roth, Jacinta A Deacon, Cassandra L Baan, Andrew Carkeet
SIGNIFICANCE: This is the first report of monocular ghost image offset thresholds measured using O optotypes. Monocular diplopia is a complaint of patients and is the result of a variety of etiologies. Furthermore, monocular image doubling also can be a confounding variable of vectographic stereoacuity tests, warranting an investigation of ghost image offset thresholds. PURPOSE: To measure ghost image offset thresholds of normal observers and how they are affected by offset orientation, target size, and ghost image relative luminance...

#5
Linda Trang Nguyen, David Yang, Lee Vien
SIGNIFICANCE: Transitory corneal epithelial macrocysts associated with scleral contact lens wear post-penetrating keratoplasty are observed in areas of corneal edema. The macrocysts do not appear to result in complications that would prevent successful wear of scleral contact lenses. PURPOSE: The purpose of this study is to report three cases of transitory corneal epithelial macrocysts associated with scleral lenses in post-penetrating keratoplasty corneas. CASE REPORTS: Three cases including anterior segment photographs and anterior segment optical coherence tomography highlight the clinical presentation of transient corneal epithelial macrocysts...

#6
Licia Tan, Lynn Teo, Shu Yen Lee
SIGNIFICANCE: Bilateral occurrence of rhegmatogenous retinal detachment is a potentially blinding condition seen most commonly in patients with atopic dermatitis. Poor control of the skin condition may lead to simultaneous or sequential retinal detachment and even development of complications such as proliferative vitreoretinopathy. PURPOSE: The purpose of this study was to highlight the importance of the dermatologist's role in aggressive treatment of atopic dermatitis to prevent this potentially blinding condition...

Bruce Alan Furr, David C Musch, Chris A Andrews, Rachel Schumann
SIGNIFICANCE: Vision screening can identify people who have vision problems requiring a comprehensive examination. When children are screened, the most prevalent serious problem is amblyopia secondary to uncorrected ametropia. Screening also identifies strabismus, which can lead to loss of binocularity. Early diagnosis permits treatment with restoration of balanced vision and binocularity. PURPOSE: The study evaluated the testability of the Titmus V3 Vision Screener as a method to screen vision and strabismus in pre-school children...

Prachi A Dave, Kunal K Dansingani, Ayesha Jabeen, Asiya Jabeen, M Hasnat Ali, Kiran Kumar Vupparaboina, Hari Kumar Peguda, Rajeev Reddy Pappurru, Rupesh Agrawal, Jay Chhablani
SIGNIFICANCE: This study compares foveal avascular zone (FAZ) geometry in healthy eyes as imaged by two commercially available optical coherence tomography angiography (OCTA) devices. Foveal avascular zone measurements are repeatable and reproducible with each OCTA device, but interdevice agreement was poor. We provide conversion factors between devices. PURPOSE: The purpose of this study was to perform comparative evaluation of FAZ geometry in healthy eyes as imaged by two commercially available OCTA devices...

#12
Jean-Baptiste Bernard, Susana T L Chung
SIGNIFICANCE: Little is known about how the preferred retinal locus (PRL) develops in patients with macular disease. We found that acuity is worse at the PRL than at other retinal locations around the scotoma, suggesting that the selection of the PRL location is unlikely to be based on optimizing acuity. PURPOSE: Following the onset of bilateral macular disease, most patients adopt a retinal location outside the central scotoma, the PRL, as their new retinal location for visual tasks...

SIGNIFICANCE: For people with limited vision, wearable displays hold the potential to digitally enhance visual function. As these display technologies advance, it is important to understand their promise and limitations as vision aids. PURPOSE: The aim of this study was to test the potential of a consumer augmented reality (AR) device for improving the functional vision of people with near-complete vision loss. METHODS: An AR application that translates spatial information into high-contrast visual patterns was developed...

SIGNIFICANCE: A new driving simulator paradigm was developed and evaluated that will enable future investigations of the effects of the ring scotoma in bioptic drivers with diverse vision impairments and different telescope designs. PURPOSE: The ring scotoma may impair detection of peripheral hazards when viewing through a bioptic telescope. To investigate this question, we developed and tested a sign-reading and pedestrian-detection paradigm in a driving simulator...

Daniel M Laby
SIGNIFICANCE: Despite our inability to attenuate the course of many ocular diseases that can ultimately lead to loss or significantly decreased visual function, this report describes a potential technique to aid such patients in maximizing the use of the vision that remains. PURPOSE: The aim of this study was to demonstrate the applicability of utilizing sports vision training to improve objective and subjective visuomotor function in a low-vision patient. CASE REPORT: A 37-year-old woman with Usher syndrome presented with reduced central visual acuity and visual field...

Daniel M Laby, David G Kirschen, Usha Govindarajulu, Paul DeLand
SIGNIFICANCE: A visuomotor skill (eye-hand visual-motor reaction time [EH-VMRT]) important for baseball performance is described. Eye-hand visual-motor reaction time represents the integration of visual information, perceptually based decisions, and motor movements to accomplish a specific task. The speed at which this occurs depends on many factors, some visual, some perceptual, and some motor related. PURPOSE: The purpose of this study was to describe the EH-VMRT ability and evaluate its relationship to the baseball batting performance of professional baseball players...

Hui-Ying Kuo, David A Atchison, Katrina Leanne Schmid
SIGNIFICANCE: Central motion perception, as assessed by minimum displacement detection, was reduced in highly myopic eyes. Peripheral motion detection may be influenced by myopia, particularly in the inferior-nasal retina. PURPOSE: Motion discrimination is a complex visual task processed mainly via the magnocellular pathway. We investigated whether it is affected in myopia. METHODS: Ninety young adults aged 18 to 28 years participated: 30 emmetropes (spherical equivalent refractions +1...
