Lypka, OD, College of Optometry, Nova Southeastern University Introduction. Elevated blood pressure can lead to malignant hypertension and is a significant risk factor for the development of retinal artery occlusions. New management guidelines indicate that patients with transient ischemic attacks, including transient monocular vision loss, and retinal artery occlusions should be urgently referred to a specialized stroke unit for proper assessment. Case presentation. A 50-year-old Haitian male patient with symptomatic dimming vision presented with malignant hypertension along with a branch retinal artery occlusion in the right and a suspected previous central retinal artery occlusion in the left eye, evidenced by a history of sudden, painless vision loss, an atrophic retina, attenuated sclerotic arterioles and optic nerve head pallor. Deviation From the Expected. Hypertension is a systemic condition. Here, we discuss a unilateral presentation of malignant hypertension secondary to a previous retinal artery occlusion leading to inner retinal cell death and necrosis. Discussion. Transient vision loss can occur secondary to retinal artery occlusions and is an established prodromal indicator of ischemic stroke. 10-15% of patients experiencing a TIA have a stroke inside 90 days, half of those transpire within 48 hrs. 24% of patients have shown acute ischemic strokes on MRI, while neurologic signs and symptoms were not present in 38% of those individuals. Conclusion. Patients with transient ischemic attacks and retinal artery occlusions need to be further investigated for a stroke with referral to a specialized stroke unit and a diffusion-weighted MRI. Grants.

Kolber, Ph.D., Associate Professor, Dr. Pallavi Patel College of Health Care Sciences, Nova Southeastern University Peter A. Sprague, DPT, Associate Professor, Dr. Pallavi Patel College of Health Care Sciences, Nova Southeastern University Emily Passint, Dr. Pallavi Patel College of Health Care Sciences, Nova Southeastern University Dominic Mascia, Nova Southeastern University Michael Marquis, Nova Southeastern University Objective. Determine the test-retest reliability and minimum detectable change (MDC) of a dynamometric device (DYN) used to quantify isometric lifting strength. Background. The ability to perform lifting maneuvers from varying heights is a basic activity of daily living. Lifting assessments are used to quantify strength, profile injury risk, and determine work capacity. Vertical lifting strength from below the waist may be quantified using free- weights, lift- boxes, and dynamometry. While DYNs are most efficient for testing time and portability (eliminate need to use weights), a paucity of research exists to determine their reproducibility and error-based clinimetric properties. Methods. Fifty healthy participants (mean age 25-years) were recruited via convenience sampling. Following consent, participants underwent a brief warm-up followed by the lifting assessment. Participants stood on a platform; knees and hips slightly flexed, maintained a lumbar spine lordosis and grasped the DYN handle at knee level. Upon command, participants lifted in a vertical direction with maximum effort. Four repetitions were completed 1-minute apart and repeated 48-hours later. Results. Intersession test-retest reliability was excellent, with an intraclass correlation coefficient (3,1) = .969. The MDC (90% confidence interval) was 18 kilograms (kg). Conclusion. The DYN used in this study possessed excellent reliability during the initial phase of lifting where physical demands are the greatest. The MDC 90 indicates that changes of 18kg or greater are needed to exceed the threshold of error. A limitation of this study is the use of an isometric task, which is only one position of a dynamic functional lifting task.
