More PD loss was associated with lower OCT and OCT-angiography signal strength (odds ratio [95% confidence interval], 0.64 [0.40, 0.96] and 0.60 [0.38, 0.86], per dB, respectively), thicker retinal nerve fiber layer thickness (1.08 [1.01, 1.16] per μm), and female sex (6.57 [1.25, 48.79]).

Less than one-third of patients with early glaucoma had more loss of perfusion compared with conventional structural loss in the macula. Even within a range of high-quality images, lower signal strength may be at least partially responsible for apparent perfusion loss.

To assess the influence of artificial tears of different viscosity on K-readings prior to cataract surgery.

Prospective randomized crossover, before-and-after clinical study.

Setting Department of Ophthalmology, Medical University of Vienna.

A total of 123 eyes of 80 patients prior to cataract surgery were assigned to 2 groups based on normal and dry eyes.

Two native baseline keratometries were followed by instillation of either high- or low-viscosity eye drops. Keratometry was repeated 30 seconds, 2minutes, and 5minutes after instillation.

Influence of eye drops of different viscosity in normal and dry eyes on short time K-readings.

Repeatability between native baseline measurements was high (standard deviation= 0.02mm in normal and in dry eyes). In normal and dry eyes, a statistically significant increase in measurement variability after instillation of both low-viscosity and high-viscosity eye drops was observed (P < .01). Measurement variability was most pronounced between baseline measurement and 30 seconds and diminished over time. Variability of K-readings appeared higher in dry eyes compared with normal eyes. Astigmatism changed more than 0.5 diopters in 13.2% of normal eyes and 34.4% in dry eyes using eye drops of high viscosity.

Tear film-stabilizing eye drops prior to keratometry measurements influenced K-readings significantly, especially in dry eyes. Selleckchem Liproxstatin-1 A time period of more than 5minutes should be allowed to pass after instillation of eye drops. The higher the viscosity of the eye drops, the stronger the influence and the longer its persistence.

To determine the preoperative characteristics and surgical results after medial rectus advancement in patients with secondary exotropia.

Retrospective, interventional case series.

Setting Tertiary Care University Medical Center. PatientPopulation 221 patients with a diagnosis of secondary exotropia who underwent medial rectus advancement surgery by a single surgeon.

Preoperative demographics, exodeviation and motility, intraoperative findings, and postoperative results were recorded. MainOutcomeMeasure Success of surgery, defined as Esotropia <15 prism diopters (pd) at postoperative week 1, or any deviation of <8 pd at postoperative month 2 (POM2).

A total of 98 patients underwent unilateral medial rectus advancement (UMRadv), 89 underwent UMRadv with lateral rectus recession (LRc), and 34 underwent bilateral medial rectus advancement (BMRadv). POM2 success rates were 66.7% in UMRadv patients, 62.1% in UMRadv+ LRc, and 56% in BMRadv. A total of 117 patients had preoperative adduction deficits,rection at postoperative week 1 can improve final outcomes.

Medial rectus advancement results in successful surgical results at POM2 for secondary exotropia.

We compared and analyzed the concentrations of vitamin C, vitamin E, zinc, and copper in both national and regional brands of dietary supplements recommended for patients who are at risk for macular degeneration.

Prospective cross-sectional study.

National brand name and generic multivitamin formulations for age-related macular degeneration were obtained. Comparative analysis of the vitamin C and vitamin E content was performed by gas chromatography-mass spectrometry and the zinc and copper content was analyzed by atomic absorption spectroscopy in an institutional chemistry laboratory.

All national brand name vitamins, both tablet and gel capsule formulations, and generic brands in tablet form were relatively accurate in their product labeling. For most of the samples tested, the measured quantities of vitamin C, vitamin E, zinc, and copper were slightly higher than labeled but not to an amount that would cause any systemic toxicity if taken at the recommended dosages.

Physicians may recommend national brand name vitamins and generic brands in tablet form to their patients with some confidence; however, the content may have some inaccuracies regarding labeling.

To evaluate cataract surgery complexity and complications among US Medicare beneficiaries with and without dementia.

Retrospective claims-based cohort study.

A 20% representative sample of Medicare beneficiaries, 2006-2015.

Dementia was identified from diagnosis codes on or prior to each beneficiary's first-eye cataract surgery. For each surgery, we identified setting, routine vs complex coding, anesthesia provider type, duration, and any postoperative hospitalization. We evaluated 30- and 90-day complication rates-return to operating room, endophthalmitis, suprachoroidal hemorrhage, retinal detachment, retinal tear, macular edema, glaucoma, or choroidal detachment-and used adjusted regression models to evaluate likelihood of surgical characteristics and complications. Complication analyses were stratified by second-eye cataract surgery within 90days postoperatively.

We identified 457,128 beneficiaries undergoing first-eye cataract surgery, 23,332 (5.1%) with dementia. None of the evaluated surgical complications were more likely in dementia-diagnosed beneficiaries.
