title: Count sir Luigi Preziosi and his glaucoma operation: the development of early glaucoma filtering surgery.
abstract: Count Sir Luigi Preziosi (1888-1965) was a famous ophthalmologist from the island Republic of Malta. He received his ophthalmic training in Rome and the United Kingdom. He practiced ophthalmology in Malta for 45 years and was a professor at the University of Malta. Like many physicians in Malta, he was active in the politics and governance of his country, serving as president of the Senate, president of the National Congress to draft a new constitution, and, finally, as president of the National Assembly of Malta. His most important ophthalmologic contribution was the development of the thermal sclerostomy filtering operation for glaucoma, which he first described in 1924. He referred to this operation initially as electro-cautery puncture and later simply as Preziosi's operation. Many surgeons considered this procedure an advance over the other available filtering operations such as sclerectomy, iridencleisis, and trephination. The operation was then further developed in 1957 by Harold G. Scheie of the University of Pennsylvania. Scheie referred to his procedure as peripheral iridectomy with scleral cautery, and it was a standard filtering operation for glaucoma for many years until the development of trabeculectomy.
