Question: 1 / 400

What is one of the slowest progressing types of glaucoma?

Angle-closure glaucoma

Open angle

Open angle glaucoma is indeed one of the slowest progressing types of glaucoma. This condition is characterized by a gradual increase in intraocular pressure that often goes unnoticed for many years, as it typically does not cause any symptoms in the early stages. Over time, it can lead to a slow loss of peripheral vision, which may not be detected until significant damage has occurred.

The slow progression is largely due to the way fluid drains from the eye. In open angle glaucoma, the drainage canals remain unobstructed but the drainage may be inefficient, leading to a gradual buildup of pressure. This contrasts with other types of glaucoma, such as angle-closure glaucoma, where the intraocular pressure can spike rapidly, causing acute symptoms. Normal-tension glaucoma can also progress slowly, but it tends to be associated with fluctuations in pressure and is not solely related to increased eye pressure, making open angle glaucoma more classically recognized for its gradual nature. Secondary glaucoma can result from other eye conditions or diseases and its progression can vary widely depending on the underlying cause.
