Associations Between Retinal Artery/Vein Occlusions and Risk of Vascular Dementia.

Background: Vascular disease is a risk factor for Alzheimer's disease (AD) and related dementia in older adults. Retinal artery/vein occlusion (RAVO) is an ophthalmic complication of systemic vascular pathology. Whether there are associations between RAVO and dementia risk is unknown.

Modified conjunctival flap as a primary procedure for nontraumatic acute corneal perforation.

Objective: Appropriate management of nontraumatic acute corneal perforation is always a challenge even with the many advances in surgical materials and techniques. We reported the outcomes of a case series of acute corneal perforation repair using a newly modified conjunctival flap with amniotic membrane transplant (AMT), fibrin glue, and a bandage soft contact lens (BCL).

Materials And Methods: A total of 13 consecutive referral cases with nontraumatic acute corneal perforation at the University of Washington were reviewed.

Resident-performed laser peripheral iridotomy in primary angle closure, primary angle closure suspects, and primary angle closure glaucoma.

Purpose: To investigate the power use and complication frequency of resident-performed laser peripheral iridotomy (LPI).

Methods: A retrospective analysis of 196 eyes from 103 patients who underwent neodymium: yttrium-aluminum-garnet laser iridotomy performed by resident physicians from January 1, 2010 through April 30, 2015 at a university-based county hospital was done. All patients were treated for primary angle closure, primary angle closure suspects, and primary angle closure glaucoma.

Accelerometer measured physical activity and the integrity of the anterior visual pathway in multiple sclerosis.

Purpose: To examine the associations among objectively-measured physical activity with the optical coherence tomography (OCT) metrics of retinal nerve fiber layer (RNFL) thickness and total macular volume (TMV) in persons with multiple sclerosis (MS).

Methods: Eighty four participants with MS, without ocular disease or high myopia underwent a neurological examination for Expanded Disability Status Scale (EDSS) scoring, followed by OCT. Participants then wore an accelerometer during the waking hours of a 7-day period to objectively measure physical activity as steps/day.
