NEI Launches Cogan Ophthalmic Pathology Collection

The National Eye Institute recently announced a new online resource for pathologists, ophthalmologists, optometrists and students. The David G.

Kupfer welcomes Cogan’s daughters
Dr. Priscilla Cogan (l) and Polly Cogan Parson (r). Kupfer was instrumental in bringing their father to NEI. Many warm memories and stories were shared during the day’s events.

The collection contains 1,040 cases and 3,000 slides culled from the more than 6,000 cases from Cogan's clinical practice. Cogan, a distinguished ophthalmologist and researcher, was professor and chairman of the department of ophthalmology at Harvard Medical School and senior scientist emeritus at NEI.

Kupfer and Yuriko Kuwabara examine the Internet-accessible Cogan Collection of 3,000 slides from 1,040 clinical cases collected by Cogan during his career as a clinician and research ophthalmologist. Kuwabara is the daughter of Dr. Toichi Kuwabara, a long-time friend and scientific colleague of Cogan. The two made a formidable team in ocular clinical pathology.

Dr. Carl Kupfer, founding director of NEI, worked for several years converting Cogan's lifetime collection of slides and clinical descriptions into an easily navigable clinical archive. The announcement and availability of the Cogan Collection took place on June 13 at the Lawton Chiles International House (Stone House). The agenda included introductory remarks by Dr. Paul Sieving, NEI director, a presentation by Kupfer of representative case studies from the web site and comments by invited guests.
