A pimple-like growth on the eye is usually considered to be the occurrence of blepharitis, blepharocyst or cornea. When a pimple-like protrusion appears, do not squeeze or pick at it directly with your hand to avoid hurting your eye or causing an infection. If it is relatively small and does not interfere with vision, observation is sufficient. Instead, it is recommended that different countermeasures be taken for different reasons for the appearance of the swelling: 1. Blepharitis: known as mydriasis, commonly known as needle’s eye, is an acute purulent inflammation of the eyelid glands, often due to staphylococcal infection. The clinical symptoms are mainly redness, swelling, heat, hard nodules and pressure pain in the affected area, some of which will subside on their own after developing to a certain extent. Patients can be treated with local antibiotic eye ointment, such as erythromycin eye ointment, tetracycline eye ointment, etc.; if an abscess is formed, it should be promptly incised to drain the pus. In the late stage, hot compresses can be applied to reduce discomfort and promote the remission of mydriasis. 2. Chalazion cysts: called chalazion, are mostly due to obstruction of the outlet of the lid gland and the secretions of the gland are retained in the lid, causing chronic irritation of the surrounding tissues, which in turn leads to aseptic chronic granulomatous inflammation. In milder cases, they are self-absorbing and can be relieved by appropriate hot compresses; in larger masses, patients who do not see remission after conservative observation or hot compresses can have the cyst surgically removed before the mass can be completely absorbed; 3. Cornuoles: benign swellings or retention cysts originating from the epidermis or epithelium of the appendages. It appears as a yellowish-white, firm papule. Generally no conscious symptoms, usually do not need treatment, if necessary, under the guidance of the doctor can be used to local laser ablation and other methods of medical treatment.
