Side-by-side medical illustrations of an eye show retinal detachment on the left, with a retinal break and detached retina labeled, and a scleral buckle procedure on the right, where a band encircles the eye to repair the detachment. Key eye structures such as the sclera, choroid, retina, and eye muscles are labeled in both diagrams.

Diagram showing how visual information from an object enters the left and right eyes, travels along the optic nerves, crosses at the optic chiasma, and reaches the occipital lobes in the brain for image processing.

Side-by-side diagrams compare a nearsighted eye, where light focuses in front of the retina, with a normal eye, where light focuses on the retina. Both eyes are labeled with cornea, lens, retina, and sclera.

Side-by-side diagram comparing a farsighted (hyperopic) eye and a normal eye, showing how light focuses behind the retina in hyperopia and directly on the retina in a normal eye, with labeled parts including lens, cornea, sclera, and retina.

Side-by-side medical diagrams compare an eye with astigmatism to a normal eye, showing how light rays focus at multiple points in the astigmatic eye and at a single point in the normal eye. Key parts labeled include lens, cornea, retina, and sclera.
