LSGPA Invests an Additional $500,000 in MacuLogix


HARRISBURG, Pa.--(BUSINESS WIRE)--The Life Sciences Greenhouse of Central Pennsylvania (LSGPA) announced today an additional investment of $500,000 in MacuLogix, Inc. The investment was part of a syndicate with other, unnamed investors and brings LSGPA’s total investment in the Middletown-based firm to over $2 million.

MacuLogix is the developer of the AdaptDx, an automated dark adaptometer that enables eye care professionals to diagnose, monitor and treat age-related macular degeneration (AMD) well before vision loss occurs. It works by measuring a patient’s dark adaptation function, the recovery of vision when going from daylight to darkness.

AMD is a chronic, progressive disease and the leading cause of adult blindness – it affects more than 14 million Americans alone. Fortunately, with early detection, there are steps that can be taken to slow progression, such as lifestyle changes, smoking cessation and nutraceutical supplementation.

According to MacuLogix’s Co-founder and Chief Technology Officer, Gregory R. Jackson, PhD, roughly 25% of AMD goes undiagnosed by primary eye care professionals. “We can, and should, do better,” says Jackson. “The AdaptDx technology makes early detection not just easier, but faster and more reliable as well.”

“MacuLogix is filling an unmet need in healthcare while creating high-quality jobs here in central Pennsylvania,” said LSGPA President and CEO, Mel Billingsley, PhD. “The company’s prospects for growth and the potential to save the eyesight of millions, combined with the continued confidence of our co-investors, made further investment in MacuLogix an easy choice for LSGPA.”
