Jules Gonin. Pioneer of Retinal Detachment Surgery

Thomas J Wolfensberger, MD, PD, MER

Before the turn of the 20th century, eyes with a retinal detachment were considered doomed. Contrary to other branches of ophthalmology, such as cataract extraction, the surgical treatment of retinal detachment was still in its infancy, and the surgical success rates were less than five percent. From 1902 to 1921 Jules Gonin almost single handedly changed the landscape of retinal detachment surgery forever. He recognised that the retinal break was the cause . and not the consequence as it was largely believed at the time - of the retinal detachment, and that the treatment had at all costs to comprise the closure of the break by cauterisation. He named the procedure ignipuncture, as he cauterised the retina through the sclera with a very hot pointed instrument. Despite rigorously detailed clinical observations and increasing success rates, his discovery was not readily accepted and sometimes openly opposed by a large part of the ophthalmic establishment. It was not until 1929 that he received worldwide acclaim at the International Ophthalmological Congress in Amsterdam for his surgical technique. His legacy lives on in the eye hospital in Lausanne that bears his name, in the Gonin Medal awarded by the International Council of Ophthalmology every four years for the highest achievement in ophthalmology, and in a street named after him, the very street that he used to walk from his home to the hospital every day.

The importance of Jules Gonin in the development of modern retinal detachment surgery cannot be underestimated. Between 1902 and 1921 he developed his understanding of how retinal detachments formed and how they had to be effectively treated. The story of his life is an illustration of how an ophthalmologist persevered with his diligent studies for almost 20 years until his research bore its fruits.

Early years

Jules Gonin was born in Lausanne, the French part of Switzerland on 10 August 1870. In the 17th century, his ancestors had been forced to leave their native Piedmont in the north of Italy due to religious persecution. The young Jules grew up in a family where culture and religious faith were the pillars of communal, and his schooling at the local Lycée soon started to show his extraordinary talent for languages. He spoke French, Swiss German, and added Latin and Greek with little effort. He also studied English, Spanish and Italian and became proficient in all of them. 1

In 1888 he enrolled in the College of Sciences and studied medicine at the University of Lausanne. He was very active in his fraternity called the Zofingia, and lobbied hard to abolish certain fencing rituals that were a part of the group's activities. After completing some research studies on butterflies, which earned him a distinction from the University, he entered the Institute of Pathology in Lausanne. After several travels around Europe during 1894-1895 to visit different hospitals in Paris, London, Berlin, Heidelberg, Vienna and Prague, he was drawn to ophthalmology. Dr. Marc Dufour, the director of the Eye Hospital in Lausanne at the time, offered him a post in 1896 to start his training. The Eye Hospital in Lausanne had started off as an asylum for the blind built in the first half of the 19th century (Figure 1).

In 1873 a new hospital was erected next to it and it was only then that a proper eye department was opened with a permanent medical staff (Figure 2).
