Can your patients with heart failure see? The prevalence of visual impairment among adults with heart failure.
This study used data from the 2005-2008 National Health and Nutrition Examination Survey to determine the prevalence of visual impairment among adults with heart failure. There is a higher prevalence of visual impairment with that cohort, even with wearing glasses. This finding warrants more collaboration between general internists, cardiologists, ophthalmologists, and other caregivers.

Patient harm in cataract surgery: a series of adverse events in Massachusetts.
This study examined the reported adverse events (AEs) involving cataract surgery in Massachusetts from 2011 to 2015. There were 37 AEs reported, with 15 anesthesia related, 5 were wrong eye blocks, 3 cases of hemodynamic instability, 2 retrobulbar hematoma/hemorrhages, and 5 globe perforations resulting in permanent loss of vision. However, the authors believe the numbers reported to Massachusetts state agencies are lower than the true number of AEs.

Preventing adverse events in cataract surgery: recommendations from a Massachusetts expert panel.
The purpose of this article is to identify contributing factors to the adverse events (AEs) reported in Massachusetts and present the panel's recommended strategies to prevent them. The panel identified 2 principal categories of contributing factors to the state's cataract surgery-related AEs: systems failures and choice of anesthesia technique. The panel recommended several strategies to prevent AEs during cataract surgery, including performing a distinct time-out with at least 2 care-team members before block administration.

Patient-physician communication on medication cost during glaucoma visits.
The aim of this secondary analysis was to describe the frequency and nature of patient-physician communication regarding medication cost during glaucoma office visits. Most participants did not discuss medication cost during their glaucoma office visit. The majority of the subjects who discussed cost had mild disease severity (51 percent), took one glaucoma medication (63 percent), and had Medicare (49 percent) as well as a form of prescription insurance (78 percent).

Vision screening in children aged 6 months to 5 years: Evidence report and systematic review for the US Preventive Services Task Force.
The researchers reviewed the evidence on screening for and treatment of amblyopia, its risk factors, and refractive error in children aged 6 months to 5 years to inform the US Preventive Services Task Force. They concluded that studies directly evaluating the effectiveness of screening were limited and do not establish whether vision screening in preschool children is better than no screening.

MIRank-KNN: multiple-instance retrieval of clinically relevant diabetic retinopathy images.
Computer-aided diagnosis has the potential of improving diabetic retinopathy (DR) screening or diagnosis. The researchers developed a feature space of a modified color correlogram appended with statistics of steerable Gaussian filter responses selected by fast radial symmetric transform points. Experiments with real DR images collected from five different datasets demonstrate that the proposed approach is able to outperform existing methods.

Visual acuity and self-reported vision status.
This study examined the associations of two measures of vision impairment (i.e., a clinical measure of visual acuity and self-reported vision status) and social isolation in a nationally representative sample of Americans aged 60 and older. Effects of both measures of vision impairment in predicting social isolation were substantially reduced or eliminated in adjusted models.

Cataract surgery complications and revisit rates among three states.
The authors studied cataract procedures from California, Florida, and New York, to characterize population-based 30-day procedure-related readmissions following surgery. Their results highlight the importance of age as a risk factor for cataract surgery readmissions, and suggest a relationship between black or Hispanic race, Medicaid insurance, and diabetes associated with higher risk for cataract surgery complications.

Screening for impaired visual acuity in older adults: updated evidence report and systematic review for the US Preventive Services Task Force.
This update of a 2009 systematic review on screening for impaired visual acuity among older adults found that new evidence on the diagnostic accuracy of visual acuity screening tests was limited and consistent with previous findings that screening questions or a visual acuity test was associated with suboptimal accuracy. Direct evidence found no significant difference between vision screening in older adults in primary care settings vs no screening for improving visual acuity or other clinical outcomes.

The effect of Medicaid adult vision coverage on the likelihood of appropriate correction of distance vision: evidence from the National Health and Nutrition Examination Survey.
This paper examined whether providing adult vision benefits is associated with an increase in the percentage of low-income individuals with appropriately corrected distance vision as measured during an eye exam. Findings imply that Medicaid adult vision coverage is associated with a significant increase in the percentage of Medicaid beneficiaries with appropriately corrected distance vision.
