Description
Technical Field
The utility model relates to an eye disease treatment device, in particular to an eye patch for treating xerophthalmia.
Background
Dry eye is one of the most common eye diseases, and the main symptoms include dry eye, itchy eye, photophobia, foreign body sensation, burning sensation, and eye swellingPain, etc., which often causes patients to be not durable and serious patients may have general symptoms such as insomnia and headache, etc., affecting learning and working. According to the data of epidemiological investigation, the prevalence rate of dry eye in China is about 5-34%, and by conservative estimation, about 3.2 hundred million people in China suffer from dry eye. Meibomian Gland Dysfunction (MGD) is the most common cause of dry eye, with MGD causing more than about 70% of dry eye patients. It is generally considered that the meibomian gland is dysfunctional and the lipid components secreted from the meibomian gland are changed, which causes the lacrimal fluid to be in a hypertonic state, resulting in damage to the ocular surface tissues[4]. In addition, abnormal meibomian gland secretion causes changes in tear components, and thus evaporation of water in tears cannot be effectively shielded, resulting in dry eye in which tears evaporate too quickly.
The treatment of dry eye is mainly to supplement tears, and artificial tears are the first to be used clinically. Since the improvement of artificial tears, sodium hyaluronate eye drops, polyethylene glycol eye drops and the like are commonly used in clinic at present, the moisture of tears can be well kept, excessive evaporation is avoided, and in addition, the mucin protective agent is used for treating dry eyes. Although these treatments improve the ocular surface environment from different aspects, alleviating the symptoms of the patient, they still do not fundamentally solve the problem.
The method of traditional Chinese medicine steam fumigation and the like has a certain effect on clinical treatment of dry eye, and also becomes a method for clinical treatment of dry eye. However, traditional Chinese medicine fumigation requires instruments, some instruments are large and need to be used in hospitals, and the traditional Chinese medicine fumigation is very inconvenient in treatment. At present, a portable traditional Chinese medicine dry eye fumigation therapeutic instrument appears, but the operation method is complex and the use is inconvenient, and in addition, the operation is complex for old people, so the instrument is not completely suitable.
