French ophthalmologists

André Rochon-Duvigneaud (7 April 1863 – 24 November 1952) was a French ophthalmologist born in Dordogne.
He studied medicine in Bordeaux, and in 1889 became an intern at the Hôtel-Dieu in Paris. In 1892 he earned his doctorate with a thesis on the anatomical angle of the eye's anterior chamber and Schlemm's canal. In 1895 he was appointed chef de clinique. In 1926 he retired from clinical medicine, dedicating himself to comparative studies on the eyes of various animal species. In 1940 he became a member of the Académie de Médecine.
In 1896 he described a neurological disorder characterized by exophthalmos, diplopia, and anaesthesia in regions innervated by the trigeminal nerve, occurring with a traumatic collapse of the superior orbital fissure. At the time he referred to the condition as "sphenoidal fissure syndrome", later to be known as "Rochon-Duvigneaud's syndrome". Also, he is credited with identifying recessive-inherited glaucoma with buphthalmos in New Zealand white rabbits.

Félix de Lapersonne (29 September 1853, Toulouse – 4 July 1937) was a French ophthalmologist.
Born in Toulouse, he served as interne and chef de clinique (i.e. residency) under Photinos Panas (1832–1903) in the ophthalmology clinic at the Hôtel-Dieu de Paris. In 1890 he was appointed professor of ophthalmology to the faculty at Lille, serving as dean until 1901. Afterwards, he returned to Paris, where he worked as professor of clinical ophthalmology. He was a member of the Académie de Médecine, and a chevalier of the Légion d'honneur.As an ophthalmologist, Lapersonne made contributions in his investigations of syphilitic optic neuritis, and ophthalmoneuromyelitis (Devic's disease). "De Lapersonne's capsulo-iridotome", a punch forceps used in eye surgery, is named after him.

Pierre-Félix Lagrange (22 January 1857 – 22 April 1928) was a French ophthalmologist.

Ferdinand Monoyer (9 May 1836 – 11 July 1912) was a French ophthalmologist, known for introducing the dioptre in 1872.
He invented the Monoyer chart, used to test visual acuity. He inserted his name in the random letters of the chart. It appears when one reads vertically from bottom to top on each side.
