The Eyeball Anatomy!
Let there be a transfer of light - Read on, your going to love it! Instagram @rev.med We see stuff, stuff passes through the front of the eye (cornea) through the lens. Cornea and lens focus the stuff coming in and lay it all down on the bed. The bed has sheets on the back of the eye called the Retina. This Retina absorbs the stuff turns them into electrochemical impulse and sends it off running the Optic nerve marathon till it reaches the finish line, our REV Med brain! Repeat this to someone and DM us Anatomy of the Eyeball *Optic Nerve - Our connection to the brain, interesting the retina sees upside down, brain turns it right side up, more later. Damage to optic nerve.. think Glaucoma. *Choroid - Blood vessels that lines the back of the eye. Between retina and sclera. *Pupil - The black spot in our eye. Pupil changes size to adjust amount of light. Think Marcus Gunn pupil, you were just about to say that right? *Cornea - Clear front window of the eye, transmits and focuses light into the eye. You know laser surgery? It reshapes your cornea basically ultimately changing your focus. *Vitreous Humor - clear gelatinous substance found in the central cavity of the eye. *Retina - Nerve layer bed sheets that line the back of the eye. Its what senses the light and sends it towards the Optic nerve. *Iris - The colored part, regulation of amount of light. Bright light —> iris closes pupil = less light. Low light, the iris opens up the pupil to let more light in. *Lens - Focuses light towards the retina. Think aging, ‘Cataracts’ it deteriorates as we age. *Macula - Area in retina containing special light sensitive cells. Center of visual field, able to see fine details clearly. Aging results in Macular degeneration… you already knew that. *Sclera - White coat the eye wears to feel like a doctor!
