Overview

The ocular system captures light and converts it into neural signals for vision. Key structures include the cornea lens retina optic nerve and extraocular muscles. Ocular blood supply and intraocular pressure maintain function and ocular health.

Anterior Segment

The cornea anterior chamber iris and lens focus light onto the retina and regulate intraocular pressure. Aqueous humor dynamics influence glaucoma risk. Slit lamp and ultrasound imaging evaluate anterior segment pathology.

Retina and Optic Nerve

The retina contains photoreceptors and neural layers that transduce light into electrical signals. The optic nerve transmits visual information to the brain and is vulnerable to ischemic and compressive injury. Fundus imaging OCT and MRI assess retinal and optic nerve disease.

Clinical Relevance

Ocular conditions include cataract glaucoma retinal detachment and optic neuropathy. Timely diagnosis and intervention preserve vision and prevent irreversible loss. Multimodal imaging guides surgical and medical management.
