H42: Glaucoma in diseases classified elsewhere
Glaucoma in diseases classified elsewhere (H42) refers to a group of eye conditions that are caused by other underlying diseases. These conditions result in an increase in intraocular pressure - the pressure within the eye - which often leads to damage to the optic nerve, the nerve responsible for vision. Though it is not specific to any one disease, it is commonly associated with conditions like diabetes or hypertension. Symptoms may vary, but the most common ones include pain around the eyes, blurred vision, seeing halos around lights, and gradually decreased peripheral vision. As the disease progresses, it can lead to irreversible blindness if untreated. The onset is usually slow and the disease often presents asymptomatically in the early stages necessitating regular eye check-ups particularly in those with risk factors.
