WATERTOWN, Mass. -- March 20, 2013

pSivida Corp. (NASDAQ:PSDV; ASX:PVA), a specialty pharmaceutical company that
is a leader in the development of sustained release ophthalmic drug
treatments, today announced that the Company’s Vice President of Research, Dr.
Hong Guo, will present a paper at the 5^th Ocular Diseases and Drug
Development Conference in San Francisco on March 21. Dr. Guo’s presentation
will take place at 10:30 a.m.

Dr. Guo’s presentation entitled “Sustained delivery of proteins and
anti-bodies” is expected to discuss recent developments in pSivida’s Tethadur
technology.

“One of the many challenges to the pharmaceutical industry is to develop
effective delivery systems for protein and antibody drugs,” said Dr. Paul
Ashton, President and CEO of pSivida. “Dr. Guo will describe results we have
had with our proprietary Tethadur system, which is based on bioerodible,
nanostructured, porous silicon. With the large number of biologic patents
expiring and the development of the Bio-similar field, improved protein
delivery will become increasingly important.”

pSivida has previously announced a technology evaluation agreement with a
leading global biopharmaceutical company investigating the use of this
technology in ophthalmology.

The Ocular Diseases and Drug Development Conference promotes the discovery of
ocular disease development by bringing together leading scientists,
researchers and experts to discuss and collaborate on the latest research and
development, safety assessment, regulatory issues and drugs in development for
combating and curing age-related macular degeneration (AMD), diabetic
retinopathy, glaucoma, DME, uveitis and other ocular diseases. Among those
participating are representatives from most of the pharmaceutical companies
that are involved in the development of treatments for these conditions.
