Regarding fovea, which of the following statements is true –a) Has the lowest threshold for lightb) Contains only conesc) Contains only rodsd) Maximum visual acuitye) Is located at apex of optic nerve
Fovea centralis contains only cones; therefore, has maximum visual acuity and lowest threshold for light.
Option d is absurd as there is no apex in the optic nerve. It is orbital apex where the optic nerve enters the eye socket.
