Utilization and Abandonment of Low Vision Devices Prescribed on a Mobile Clinic.

Significance: Device utilization and abandonment for patients seen on a mobile clinic are explored. Findings are informative for resource allocation in a novel low vision rehabilitation (LVR) delivery model. This study also explores the relationships between device abandonment and LVR patient-reported functional outcomes.

Clinical outcomes of low vision rehabilitation delivered by a mobile clinic.

Purpose: This prospective cohort study examined clinical outcomes of low vision rehabilitation (LVR) delivered by a mobile clinic.

Methods: Participants were recruited from those scheduled for mobile clinic LVR and met the United States definition of legal blindness. Participants completed the Massof Activity Inventory (AI) before LVR, 3 months post-LVR, and 1 year post-LVR.

Abandonment of low-vision devices in an outpatient population.

Purpose: To investigate abandonment rate of prescribed low-vision devices for near tasks and factors associated with abandonment in a U.S. outpatient population.

Survey of optometric low vision rehabilitation training methods for the moderately visually impaired.

Purpose: The goal of this survey study is to determine the low vision rehabilitation training practices of optometrists who prescribe near magnifying devices for low vision patients who have moderate visual impairment from age-related macular degeneration.

Methods: A total of 2,028 surveys were sent electronically or by mail. A total of 136 optometrists reporting a special interest in low vision rehabilitation responded to an 18-item survey about practice mode, educational background, affiliations, and other demographic information.

Low vision rehabilitation for a target-shooting marksman with visual field loss and diplopia.

Background: In the United States in 2006, there were 17.8 million hunters and 17.1 million target shooters.

Scanning eye movements in homonymous hemianopia documented by scanning laser ophthalmoscope retinal perimetry.

Sparing or partial recovery of visual fields in hemianopic patients is frequently difficult to document. This is because when testing large field losses, the standard automated or manual visual field testing systems have limited fixation controls. Measured visual field recovery in these cases may not be real but instead may be due to an artifact such as scanning eye movement.

Clinical quality assessment using computer monitor photoimages of optic nerve head cupping.

Background: Photo documentation (color slides) of abnormal optic nerve heads enable the clinician to accurately access or estimate the percentage of the optic nerve cupping to quantify the progression of glaucoma. The purpose of this study is to compare cupping estimations using digital images on a computer monitor to those using standard color slides.

Methods: Ten sets of stereo optic nerve head photos from six glaucoma suspects were used in this study.

Clinical comparison of the SITE IRAS hand-held interferometer and Haag-Streit Lotmar visometer.

The preoperative testing of retinal acuity was evaluated using two instruments in each of 35 eyes having extracapsular cataract extraction. Retinal acuity was measured using the SITE IRAS hand-held interferometer and the Haag-Streit Lotmar visometer. The postoperative findings are given for comparisons of final acuity, prediction, and instrument evaluation.

Prospective evaluation of radial keratotomy using the Fyodorov formula: preliminary report.

Eighteen eyes were preoperatively evaluated and operated on by the method of Fyodorov. Although Fyodorov stated that his formula improves the predictability of radial keratotomy, we know of no previously published studies that included it. They all omitted the Maklakov measurement of scleral rigidity, although Fyodorov stated that it may influence the surgical result profoundly.
