Glaucoma

Glaucoma is a disease in which the optic nerve inside the eye is gradually damaged by high intraocular pressure or other factors, causing the visual field to narrow progressively. There are almost no symptoms in the early stage, so detection can be delayed, and rather than a cure, lifelong consistent management is important. Detecting it early through regular checkups and starting treatment is the best way to help prevent blindness.

Head and neck cancer is a general term for malignant tumors that develop in the head and neck region, including the larynx, oral cavity, oropharynx, hypopharynx, nasal cavity, and nasopharynx. Because this area is involved in essential everyday functions such as breathing, swallowing, and speaking, treatment can be challenging. If you have a voice change lasting more than 6 weeks, a mouth sore that doesn't heal after 3 weeks, or a lump in the neck, please see an ENT (ear, nose, and throat) specialist.
