Summary Introduction

To review:

The effect of a tumor present in the pituitary gland or hypothalamus that has led to the compression of the optic chiasma on vision.

Introduction:

Vision is known as one of the dominant senses. The receptors that are involved in visualization are referred to as photoreceptors and are present in the retinal layer of the eye. The photoreceptor cells sense and further encode the light patterns that tend to enter the eyes. Rods and cones are two forms of photoreceptor cells. The rod cells provide vision in low light intensity while the cone cells provide color visions as they provide vision in bright light.
