Light Scattering By Vitreous Of Humans With Vision Degrading Myodesopsia From Floaters, Alba M Paniagua-Diaz, Justin H Nguyen, Pablo Artal, Wei Gui, J Sebag

Student and Faculty Publications

PURPOSE: Vision-degrading myodesopsia (VDM) from vitreous floaters significantly degrades vision and impacts visual quality of life (VQOL), but the relationship to light scattering is poorly understood. This study compared in vitro measures of light scatter and transmission in surgically excised human vitreous to preoperative indexes of vitreous structure, visual function, and VQOL.

METHODS: Pure vitreous collected during vitrectomy from 8 patients with VDM had wide-angle straylight measurements and dark-field imaging, performed within 36 hours of vitrectomy. Preoperative VQOL assessment with VFQ-25, contrast sensitivity (CS) measurements with Freiburg acuity contrast testing, and quantitative ultrasonography were compared to light scattering and transmission …

The Effectiveness And Outcomes Of Oculomotor And Visual Field Deficit Rehabilitation Secondary To Ischemic Cerebrovascular Accident: A Literature Review, Maanas Chiplunkar

Rowan-Virtua Research Day

Visual field loss and oculomotor dysfunctions are two common vision deficits caused by cerebrovascular accidents. Oftentimes these deficits can result in a loss of independence for patients and depression. Neurovisual rehabilitation is a frequently overlooked aspect of stroke rehabilitation, so investigating the current rehab approaches and the factors that play a role in the effectiveness of these methods is crucial so that clinicians can provide more direct and focused treatment for their patients. This literature review research process used PubMed, NCBI, and EbscoHost as primary databases. Preliminary results showed that restitutive and compensatory rehabilitation approaches are effective for treating visual …

Charles Bonnet Syndrome: A Case Report, Christian Scouarnec, Martin M. Forsberg

Rowan-Virtua Research Day

Charles Bonnet syndrome (CBS) involves nonthreatening hallucinations in patients who have no neurological and no psychological abnormalities but with significant visual impairment secondary to ocular disease, such as macular degeneration, cataracts and diabetic retinopathy. When a patient loses vision, their visual system doesn’t process new images. Without data coming through the eyes, the brain fills the void and makes up images or recalls stored images for you to see and this is what causes the hallucinations in CBS.

Many physicians are unaware of CBS and its prevalence, and with proper detection, physicians can help treat their patients with a frequently …
