Lesion of Proximal part of Optic nerve

There are two lesions

  1. Lesion of Proximal part of Optic nerve

  2. Anterior Chiasmal syndrome

Sir the fibres affected in both appear the same to me…

It’s not an early stage lesion of Ipsilateral ON that it will cause central scotoma…

So why the difference in visual field affected as shown in pic 2…

(See B(2) and C(3).)

My advice - please ignore this book.

Hve explained (i hope) very well in the videos. Feel free to watch
