The purpose of this Tutorial is to summarize these recent advances
and to describe our present understanding, based primarily on anatomic
investigations, of the Neural Organization of the Mammalian Retina. A great
addition has been a section on Psychophysics of Vision which we hope will be of
general information to all interested in learning the basics of visual
perception.

Since ocular infections are one of
the most frequent occurrences in ophthalmology, the treatment for these
infections must be fast, precise and effective. Clinical diagnosis of ocular
infections can be confirmed by several techniques based on microbiological test
of ocular samples. This guide explains about most common ocular infections and
its treatment.
