PRISM Vision Group announced it closed a transaction with Retina Macula Institute. Financial terms of the transaction were not disclosed. The partnership expands PRISM’s presence in Southern California and strengthens the organization’s retina specialty capabilities as it continues building a national ophthalmology platform.

Retina Macula Institute specializes in the diagnosis and treatment of retinal, vitreous and macular diseases and operates multiple locations across Southern California. The practice’s physicians are board-certified and fellowship-trained in medical and surgical retina care.

PRISM Vision Group, which is supported by McKesson, now includes more than 200 providers, over 90 offices and eight ambulatory surgery centers nationwide.

The transaction follows PRISM’s recent affiliation with Spokane Eye Clinic and reflects continued consolidation activity across ophthalmology and retina care. PRISM has previously expanded its retina network through affiliations with groups including The Retina Group of Washington and The Retina Care Center.
