| gutta serena | Former term for blindness of unknown aetiology; the serena suggested that the anterior segment of the eye was clear and tranquil, that there was no visible cause for the blindness, no corneal scar, no inflammation, no cataract.

With the ophthalmoscope, in 1851, the diagnosis of gutta serena suddenly became old-fashioned and inadequate. (05 Mar 2000) |
