Dr. Syed Adeel H Zaidi receives grant & Dean's Diary Mention

Syed Adeel ZaidiA $90,000 Career Starter Research Grant to Dr. Syed Adeel H. Zaidi, who is working to develop a new therapy to limit the neuronal and vascular damage associated with retinopathy of prematurity. This condition is among the most common in premature or low birth-weight babies and is a major cause of long-term vision impairment and blindness.  This new grant, which is Dr. Zaidi’s first, will help him test a new therapy for ROP in a mouse model before seeking approval and funding to move on to clinical trials. This gift is just the latest in a long history of giving by the Knights Templar, who dedicate their efforts to improving vision through research, education and supporting access to care.  Congratulations, Dr. Zaidi.
