Iritis
Plantar fasciitis, also known as plantar fasciosis or jogger's heel, is a disorder that results in pain in the heel and bottom of the foot. The pain is usually most severe with the first steps of the day or following a period of rest.  The cornea is the transparent front part of the eye that covers the iris, pupil, and anterior chamber. The cornea, with the anterior chamber and lens, refracts light, with the cornea accounting for approximately two-thirds of the eye's total optical power.  Iritis is an inflammatory condition of the colored portion (the iris which surrounds the pupil) of the eye. It causes varying degrees of redness of the eye, often with significant pain, sensitivity to light, tearing, and blurred vision. When an inflammation affects primarily the iris and ciliary body it is often called iritis. The iris is the part of the eye which is visible in the mirror and gives the eye its color, usually blue or brown. The pupil is the opening in the iris through which light passes also known as the CHOROID COAT, is the opaque middle layer of the eyeball that contains many blood vessels and provides the blood supply fro the entire eye, OPAQUE means that light cannot pass through this substance. also known as FARSIGHTEDNESS, is a defect in which light rays focus beyond the retina. This condition can occur in childhood, but usually causes difficulty after age 40. Hyperopia is the opposite of myopia. The iris, visible through the clear cornea as the colored disc inside of the eye, is a thin diaphragm composed mostly of connective tissue and smooth muscle fibers. It is situated between the cornea and the crystalline lens. The. texture, and patterns of each person s iris are as unique as a fingerprint. In the middle of a normal iris is the pupil. It is an opening that, typically, is circular and is comparable to the aperture of a camera. The pupil helps regulate the amount of light passing through to the retina, which is at the back of the eye. 1 Iritis is inflammation of the iris, the coloured part of the eyeball. 2  Iritis is uncommon, but can be due to trauma, infections, or autoimmune conditions. 3  Symptoms include pain, red eye, and often, decreased vision. 4  Optic neuritis. 5  The nerve travelling from the back of the eyeball into the brain can become inflamed. 1 A sensation of grit in the eyes, and sometimes pain, result. 2  A stye -- also known as a hordeolum -- is an infection or inflammation of the eyelid margin that can come from the hair follicles of eyelashes or from oil glands. 3  A stye is often painful and most often caused by infection. The conjunctiva is the tissue that lines the front of the eye and the underside of the eyelid. It can become infected and inflamed. Often, this is caused by an allergy or infection. Though the pain is usually mild, the inflammation causes itchiness, redness, and discharge in the eye. Eye pain is also known as ophthalmalgia. Depending on where you experience the discomfort, eye pain can fall into one of two categories: ocular pain (occurs on the eye’s surface), and orbital pain (occurs within the eye). Eye pain is common, but it’s rarely a symptom of a serious condition Eye pain that occurs deeper within the eye may feel aching, gritty, stabbing, or throbbing. This kind of eye pain may require more in-depth treatment, but it is rarely a sign of a larger, more serious condition. However, eye pain accompanied by vision loss may be a symptom of an emergency medical issue. Eye pain is also known as ophthalmalgia.
