Description

Desmarres’ opthalmoscope was introduced in 1856. Initially it was made bu Lerebours & Secretan and employed a glass mirror. Schett  (The Ophthalmoscope, 1996, p. 161) notes that  Desmarres was unhappy with the functioning of this  model and its cost. He had Charriere produce the second and much more widely adopted model, which employed a polished metal mirror.It has two para-central apertures: one was used for looking at the left eye, the other for  the right eye. It lacks the Coccius clip but retain a reversing lens, which is chipped. Length: 3″ or 7.5cm; diameter :1.75″ or 4.4cm. We are offering  a good example of the second model in its original case. Desmarres’ ophthalmoscopes do not turn up often!
