The technology described in this document can be embodied in systems and computer-implemented methods for determining a score representing an amount of staining of the cornea. The methods include obtaining a digital image of the cornea stained with a tracer material, receiving a selection of a portion of the image, and processing, by a processing device, the selection to exclude areas with one or more artifacts to define an evaluation area. For each of a plurality of pixels within the evaluation area, a plurality of Cartesian color components are determined and a hue value in a polar coordinate based color space is calculated from the components. An amount of staining of the cornea is then determined as a function of the hue value. The methods also include assigning a score to the evaluation area based on the amount of staining calculated for the plurality of pixels.

The present disclosure provides compositions and methods for treating subjects at risk for or with sensorineural hearing loss. Such compositions and methods include modulating the epigenetic status of the cell, or rate of protein degradation, to increase expression and/or levels of Atoh1 protein.

Methods of treating ocular neovascularization, e.g., associated with wet agerelated macular degeneration (AMD), using activators of AMP-activated protein kinase (AMPK) and/or of Phosphatase and tensin homolog deleted on chromosome 10 (PTEN).


Described are compositions and methods of using verteporfin-based photodynamic therapy (PDT) to increase the biomechanical strength of the cornea. More particularly, described herein are compositions and methods for cross-linking collagen in corneal tissue which are useful in the treatment of corneal ectatic disorders.

Provided are methods and compositions for treating ocular conditions characterized by the presence of unwanted choroidal neovasculature, for example neovascular age-related macular degeneration. The selectivity and sensitivity of, for example, a photodynamic therapy (PDT)based approach can be enhanced by combining the PDT with an anti-FasL factor, for example, an anti-FasL neutralizing antibody.

Methods are described for predicting ancestral sequences for viruses or portions thereof. Also described are predicted ancestral sequences for adeno-associated virus (AAV) capsid polypeptides. The disclosure also provides methods of gene transfer and methods of vaccinating subjects by administering a target antigen operably linked to the AAV capsid polypeptides.

This invention generally provides compounds, pharmaceutical compositions, and methods for their use, which include methods that result in increased expression in an Atoh1 gene (e.g., Hath1) in a biological cell. More specifically, the invention relates to the treatment of diseases and/or disorders that would benefit from increased Atoh1 expression, e.g., a hearing impairment or imbalance disorder associated with a loss of auditory hair cells, or a disorder associated with abnormal cellular proliferation.

The use of methotrexate, e.g., repeated dosing or sustained-release formulations of methotrexate, for treating or reducing risk of proliferative vitreoretinopathy (PVR) or epiretinal membranes (ERM), e.g., after surgical vitrectomy to treat retinal detachment.

Purpose: To present the current understanding of age-related macular degeneration (AMD) pathogenesis, based on clinical evidence, epidemiologic data, histopathologic examination, and genetic data; to provide an update on current and emerging therapies; and to propose an integrated model of the pathogenesis of AMD. Design: Review of published clinical and experimental studies. Methods: Analysis and synthesis of clinical and experimental data. Results: We are closer to a complete understanding of the pathogenesis of AMD, having progressed from clinical observations to epidemiologic observations and clinical pathologic correlation. More recently, modern genetic and genomic studies have facilitated the exploration of molecular pathways. It seems that AMD is a complex disease that results from the interaction of genetic susceptibility with aging and environmental factors. Disease progression also seems to be driven by a combination of genetic and environmental factors. Conclusions: Therapies based on pathophysiologic features have changed the paradigm for treating neovascular AMD. With improved understanding of the underlying genetic susceptibility, we can identify targets to halt early disease and to prevent progression and vision loss. © 2013 Elsevier Inc.
