Ophthalmic calculi are multiple hard yellow spots on the lid conjunctiva, which are degenerative products of epithelial cell accumulation and mucus concentration and pressure, never calcified, but actually conjunctival agglutination. When protruding from the conjunctival surface into the irritation of the cornea to produce a foreign body sensation, and even corneal abrasion erosion. Under surface anesthesia, with a sharp knife or a foreign body needle to remove it, this disease is most common in adults, the elderly and trachoma and chronic conjunctivitis patients. Common causes Indeed, the eyelid conjunctiva of the eye will often grow “stones”, medically known as conjunctival stones. Conjunctival stones are solidified deposits of exfoliated epithelial cells and degenerative cells that accumulate in the epithelial pits of the conjunctiva or in deep tubular crypts, etc. There is no or very little calcium deposits, and they are not true stones. Conjunctival stones are most common in adults, mainly in patients with trachoma, chronic conjunctivitis and other chronic eye diseases, mostly in the upper eyelid, eyelid conjunctiva with hard yellowish-white dot-like protrusions, like crushed rice, some scattered in the form of dots, but also can be crowded into groups. At the beginning of the location of the deeper, the stone is still buried in the conjunctiva under the edge, generally no self-conscious symptoms, and later gradually exposed on the surface of the conjunctiva, only in the hard knot protrudes on the surface of the conjunctiva when there is a foreign body sensation, and even cause corneal abrasion, in this case can be in the surface of anesthesia under the tip of a knife or needle pick out, such as the lack of irritation symptoms can be without treatment. If complicated by trachoma, chronic conjunctivitis and other diseases, the primary disease should be treated after picking. Most patients, however, may continue to grow new stones after removal and often require frequent treatment to prevent abrasion of the cornea. Chinese medicine believes that the eyelid stones for the wind evil guest in the spleen meridian, congestion in the cell eyelid, Yu long into the heat, fluid burned, stasis caused by the eyelid, the treatment can be used to clear the heart and the spleen of the depressed heat of the agent, such as within the sparse Huanglian Tang plus subtractions. Difference In fact, although called stones, eye stones are not the same as kidney stones and gallbladder stones, which are stones in the true sense of the word. “Some people are nervous when they hear that they have stones in their eyes, thinking that it is a big disease that requires surgery. In reality eye stones are just minor eye problems with no or very little calcium deposits and therefore are not true stones.” In order to reduce people’s fear of eye stones, the medical profession once wanted to change its name to “conjunctival agglutination”, but most people still call it eye stones according to the traditional custom. When the stone is just a small particle, buried under the conjunctiva, not protruding beyond the surface of the conjunctiva, the patient himself will not feel the existence of the stone, and you can temporarily ignore it. When it “emerges” out of the head, it will form an irritation to the eyelid, or even make the cornea abrasion, so that people feel the eye has a foreign body, stinging pain, you can go to the hospital to pick it out. Pick eye stones is also a small operation, in the outpatient clinic can be carried out, without hospitalization. The operation is very simple, first eye drops for surface anesthesia, clean the patient’s eyes, and then pick out the conjunctival block with a needle, costing about$20. However, some patients may continue to grow new stones after the stones are removed because eye stones are often caused by inflammation of the eye. When the inflammation is not eliminated, only the symptomatic stones are removed, the source of the disease is not broken, and the stones may reoccur the next time, just like acne on the face. If the stone grows back and becomes symptomatic, treatment should be continued to prevent abrasion of the cornea. Although there is no risk of blindness, removing stones on a regular basis can be extremely troublesome. Therefore, in order to get to the root of the problem, the patient must find out the real cause of the disease, diagnose whether his stones are caused by chronic keratitis, and then treat the inflammation. When the inflammation is gone, the stones will not persist. Prevention Since most of the stones are caused by inflammation, the preventive measures are to prevent eye inflammation, avoid conjunctival irritation and inflammation, and seek medical treatment when there is eye discomfort. Usually develop healthy eye hygiene habits, do not rub the eyes, to keep the eyes moist, ready to eye drops at any time a drop, can also prevent foreign bodies into the eyes. Contact lens wearers should pay attention to the sterilization and maintenance of the lenses, regular eye examination, if not suitable for wearing contact lenses, absolutely do not force to try. People who work in the field and live in environments prone to sandstorms are encouraged to wear protective eyewear to prevent sandstorms from blowing directly into their eyes. Although stones are only small lesions of the conjunctiva, they are a “red flag” that reminds you to pay attention to the health of the conjunctiva. Eye stones are more common in patients with chronic keratitis and in the elderly, and in order to truly prevent them, the inflammation must first be eradicated.
