pSivida Corp. (NSDQ:PSDV) is touting a study of a drug-device combination that it says helps slow the advance of a degenerative eye disease called retinitis pigmentosa.
The disease involves the gradual deterioration of the rods and cones that make up the retina. Symptoms begin with night blindness and progress over years or decades to tunnel vision and, often, total blindness. CEO Dr. Paul Ashton told MassDevice that the Watertown, Mass.-based company’s Durasert is inserted into the back of the eye, where it slowly releases a steroid called fluocinolone acetonide.
