The Different Types of Glaucoma and How They Affect Vision

Glaucoma is a group of eye conditions that damage the optic nerve, often due to increased pressure inside the eye. This damage can lead to vision loss or even blindness if not treated properly. At Optica 20 20 San Antonio in San Antonio, TX, our eye doctor provides thorough evaluations and glaucoma treatment plans tailored to each patient’s needs. Understanding the different types of glaucoma helps patients recognize symptoms early and seek the right care.

Primary Open-Angle Glaucoma

Primary open-angle glaucoma is the most common form and progresses slowly without noticeable symptoms in its early stages. It occurs when the drainage canals in the eye become less efficient, causing gradual pressure buildup. Patients may not notice vision changes until peripheral vision is significantly affected. Regular eye exams with an optometrist near you are essential for early detection and management.

Angle-Closure Glaucoma

Angle-closure glaucoma happens when the drainage angle between the iris and cornea suddenly becomes blocked. This causes a rapid increase in eye pressure, leading to symptoms such as severe eye pain, headache, nausea, and blurred vision. This type of glaucoma is a medical emergency and requires immediate treatment to prevent permanent vision loss. Our eye doctor at Optica 20 20 San Antonio can help identify risk factors and provide urgent care when necessary.

Normal-Tension Glaucoma

Normal-tension glaucoma is a form where optic nerve damage occurs despite normal eye pressure levels. This type can be more challenging to diagnose because patients may not have elevated pressure readings during eye exams. Other factors such as reduced blood flow to the optic nerve are believed to play a role. Careful monitoring and specialized glaucoma treatment strategies are important for preserving vision in these cases.

Secondary Glaucoma

Secondary glaucoma develops as a result of another eye condition, injury, or medication. It can be caused by inflammation, cataracts, eye tumors, or prolonged use of corticosteroids. This type of glaucoma requires treatment of the underlying cause alongside standard glaucoma management. Our eye doctor works with patients to address both the primary issue and its impact on eye pressure and optic nerve health.

Congenital Glaucoma

Congenital glaucoma is a rare form present at birth due to abnormal development of the eye’s drainage system. It often leads to symptoms such as enlarged eyes, light sensitivity, and excessive tearing in infants. Early diagnosis and intervention by an experienced eye doctor are crucial to prevent severe vision impairment. Optica 20 20 San Antonio offers comprehensive care to support children with this condition.
