In one embodiment, the present invention provides a device and method for treating recurrent corneal erosion. In one embodiment, the method includes the steps of contacting an epithelium layer of a cornea with an array of glass micro-rods including a plurality of sharp features having a length that penetrates a Bowman's layer of the eye, wherein the plurality of sharp features of the array of glass micro-rods produces a plurality of punctures in the Bowman's layer of the eye that are of micro-scale or less. In another embodiment, the present invention provides a method and device for drug delivery. In one embodiment, the device includes an array of glass micro-rods, wherein at least one glass micro-rod of the array of glass micro-rods includes a sharp feature opposite a base of the array of glass micro-rods, wherein the sharp feature includes a treated surface for delivering a chemical compound to the eye.

A method for diagnosing diseases having retinal manifestations including retinal pathologies includes the steps of providing a CBIR system including an archive of stored digital retinal photography images and diagnosed patient data corresponding to the retinal photography images, the stored images each indexed in a CBIR database using a plurality of feature vectors, the feature vectors corresponding to distinct descriptive characteristics of the stored images. A query image of the retina of a patient is obtained. Using image processing, regions or structures in the query image are identified. The regions or structures are then described using the plurality of feature vectors. At least one relevant stored image from the archive based on similarity to the regions or structures is retrieved, and an eye disease or a disease having retinal manifestations in the patient is diagnosed based on the diagnosed patient data associated with the relevant stored image(s).

The invention encompasses cell-based systems comprising biomarkers that respond to oxidative stress (OS) in a quantitative manner, and methods of use thereof. The systems are useful for screening, identifying and testing antioxidant agents, combinations, and formulations thereof for preventing, treating, or reducing symptoms of conditions associated with oxidative damage to cells. The cell-based systems are useful for identifying effective new antioxidant agents and for optimizing antioxidant formulations for targeted therapeutic applications. One cell-based system utilizes RPE cells of the eye for identifying and optimizing antioxidant compositions effective for treatment of age-related conditions such as macular degeneration. The cell-based systems provide a convenient, inexpensive and physiologically relevant in vitro alternative to human population-based methods for testing efficacy of nutritional and pharmaceutical compositions comprising antioxidants. The invention further encompasses nutritional or pharmaceutical compositions targeting particular diseases such as AMD, formulated using methods as disclosed herein.
