Charles Oldham studied medicine at Guy’s Hospital from 1866 to 1871. He got into the Fellowship of the Royal College of Surgeons (FRCS) in 1871. He trained in different London hospitals and began practicing with his father in Brighton in 1873. He retired in 1880. He had a collection of Stradivarius violins which he left to the British Museum. He died in 1907.
Oldham presented his first ophthalmoscope model at the International Ophthalmological Congress in 1872. It was an adaptation of the Loring scope.
Fourteen years later, in 1886, he published a report on his second model (this one). One disc has an empty opening and nine lenses. There are five convex lenses: 1,2,3,4,6 and four concave lenses: 1,2,4,8. The handle collapses. There was also an indirect lens, not present in this specimen, as shown in the old illustration.
