Does Age-Related Macular Degeneration (Amd) Treatment Influence Patient Falls And Mobility? A Systematic Review., Hannah Garrigan, Jacquelyn N. Hamati, Parth Lalakia, Rosemary Frasso, Brooke Salzman, Leslie Hyman

Student Papers, Posters & Projects

PURPOSE: Age-related macular degeneration (AMD), a leading cause of irreversible blindness, increases fall risk through impaired central vision. Falls place an enormous economic burden on healthcare systems. We hypothesized that AMD treatments may reduce patients' falls risk. This systematic review (ID #: 172623) synthesized the current understanding of wet and dry AMD treatments' impact on patient falls and mobility, connecting these two public health issues.

METHODS: On April 17, 2020, PubMed, Scopus, CINAHL, and the Cochrane Central Register of Controlled Trials were queried. Clinical trials and observational studies were included, while non-English and non-primary studies were excluded. Two authors screened, …

A Foldable Nonpenetrating Keratoprosthesis: Medium To Long-Term Clinical Results In Patients With Corneal Blindness Due To Noninflammatory Anterior Cornea Disease., Jose M Vargas, Eric Shiuey

Department of Medicine Faculty Papers

PURPOSE: To report the medium to long-term safety and performance outcomes of the KeraKlear nonpenetrating artificial cornea (KeraKlear) as the primary procedure in patients with corneal blindness due to noninflammatory anterior cornea disease.

METHODS: Fifteen patients with corneal blindness (preoperative visual acuity [VA] of ≥20/200) due to a non-inflammatory anterior corneal condition were included in this prospective, single-center study. Preoperative diagnoses included corneal scars, keratoconus, and corneal dystrophies. Diseased corneas were implanted with the KeraKlear (KeraMed Inc., Irvine, California, USA) by a single surgeon (JMV) using a femtosecond laser to create all incisions. Participants were followed up with for as …

Vitamin A And Fish Oils For Preventing The Progression Of Retinitis Pigmentosa., Stephen G. Schwartz, Xue Wang, Pamela Chavis, Ajay E. Kuriyan, Samuel A. Abariga

Wills Eye Hospital Papers

BACKGROUND: Retinitis pigmentosa (RP) comprises a group of hereditary eye diseases characterized by progressive degeneration of retinal photoreceptors. It results in severe visual loss that may lead to blindness. Symptoms may become manifest during childhood or adulthood which include poor night vision (nyctalopia) and constriction of peripheral vision (visual field loss). Visual field loss is progressive and affects central vision later in the disease course. The worldwide prevalence of RP is approximately 1 in 4000, with 100,000 individuals affected in the USA. At this time, there is no proven therapy for RP.

OBJECTIVES: The objective of this review was to …

Cost-Effectiveness Analysis Of Ocriplasmin Versus Watchful Waiting For Treatment Of Symptomatic Vitreomacular Adhesion In The Us, Arshad M Khanani, Pravin U Dugel, Julia A Haller, Alan L Wagner, Benedicte Lescrauwaet, Ralph Schmidt, Craig Bennison

Wills Eye Hospital Papers

Aim: Evaluate the cost-effectiveness of ocriplasmin in symptomatic vitreomacular adhesion (VMA) with or without full-thickness macular hole ≤400 μm versus standard of care.

Methods: A state-transition model simulated a cohort through disease health states; assignment of utilities to health states reflected the distribution of visual acuity. Efficacy of ocriplasmin was derived from logistic regression models using Ocriplasmin for Treatment for Symptomatic Vitreomacular Adhesion Including Macular Hole trial data. Model inputs were extracted from Phase III trials and published literature. The analysis was conducted from a US Medicare perspective.

Results: Lifetime incremental cost-effectiveness ratio was US$4887 per quality-adjusted life year gained …

Surgery For Post-Vitrectomy Cataract, Diana V. Do, Stephen Gichuhi, Satyanarayana S. Vedula, Barbara S. Hawkins

Journal Articles: Ophthalmology

BACKGROUND: Cataract formation or acceleration can occur after intraocular surgery, especially following vitrectomy, a surgical technique for removing the vitreous which is used in the treatment of disorders that affect the posterior segment of the eye. The underlying problem that led to vitrectomy may limit the benefit from cataract surgery.

OBJECTIVES: The objective of this review was to evaluate the effectiveness and safety of surgery for post-vitrectomy cataract with respect to visual acuity, quality of life, and other outcomes.

SEARCH METHODS: We searched CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) (The Cochrane Library 2013, Issue 4), …

PURPOSE: To determine bioactivity and duration of effect of intravitreal aflibercept injection (also known as vascular endothelial growth factor Trap-Eye) for neovascular age-related macular degeneration (AMD).

METHODS: In this double-masked, phase 1 study, 28 patients with lesions ≤12 disc areas, ≥50% active choroidal neovascularization (CNV), and best corrected visual acuity (BCVA) ≤20/40 were randomized 1:1 to a single intravitreal injection of aflibercept 0.15 or 4 mg. The primary end point was the change from baseline in central retinal/lesion thickness (CR/LT) at week-8. Secondary outcomes were the change from baseline BCVA, the change in CNV lesion size and area of leakage, …

The Assessment Of Disability Related To Vision Performance-Based Measure In Diabetic Retinopathy., Kevin J. Warrian, Luciano L. Lorenzana, Dara Lankaranian, Jyoti Dugar, Sheryl S. Wizov, George L. Spaeth

Wills Eye Hospital Papers

PURPOSE: To validate a third-generation performance-based measure of visual function titled "Assessment of Disability Related to Vision" (ADREV) in a study population of patients with diabetic retinopathy.

DESIGN: Prospective, cross-sectional study.

METHODS: Patients with nonproliferative or proliferative diabetic retinopathy, free from ocular comorbidity, were recruited from a single institute and completed the ADREV, the 25-Item National Eye Institute Visual Functioning Questionnaire (VFQ-25), and a clinical ophthalmic examination. Correlation, regression, and bootstrap analysis were conducted to determine the relationship between ADREV scoring and each of the study's clinical and self-report measures of visual ability, while controlling for potential confounders.

RESULTS: Ninety-one …
