Age-related macular degeneration (AMD) is an eye disease. It affects the central part of the retina called the macula. This is the part of the eye that controls your central, detailed vision. AMD is the leading cause of vision loss in adults over age 50. It almost always affects both eyes. The macula becomes damaged. Central vision becomes limited. But side (peripheral) vision stays clear. There are 2 types of AMD: dry and wet.
Dry AMD
Dry is the most common type of AMD. In the early stages, changes in vision may be hard to notice. Over time, your central vision may slowly worsen. You may see wavy lines and blank spots in the center of your vision. Colors may look dim. There is no way to restore vision lost from dry AMD. But it's important to closely watch the condition. It can progress into wet AMD.
Wet AMD
Wet AMD is less common but more serious. Vision loss may be faster and more noticeable. You may suddenly see dark spots, blank spots, wavy lines, and dim colors in the center of your vision. It's important to find wet AMD early. Then certain treatments may help to slow further vision loss or even improve vision. These treatments include injections, photodynamic therapy, and laser surgery.

Conjunctivitis, Allergic
Allergic conjunctivitis is caused by an allergen. Symptoms may include redness of the eye, swelling, fluid leakage, and itching or burning.
Uveitis
Uveitis is inflammation inside the eye. This can be caused by injury to the eye or disease somewhere else in the body. Symptoms include eye pain, redness, blurred vision, sensitivity to light, and floating spots in the vision.
Meibomian Gland Blockage
The meibomian glands are small glands located inside the upper and lower eyelids. They secrete oils that work with tears. If your meibomian glands become blocked by thickened oils, your eyes will become dry. Your eyes may feel irritated.
Ptosis
Ptosis is when the upper eyelid droops down more than it should. If the ptosis is severe, it may block vision.
