Glaucoma ⎯ Hereditary Adult Type 1A
Disease⁚ Glaucoma, hereditary adult type 1A. This type of glaucoma is linked to a specific gene mutation leading to optic nerve damage. It causes increased eye pressure٫ affecting peripheral vision and often results in vision loss. Genetic testing is crucial for diagnosis and exploring treatment options.
Overview of Glaucoma
Glaucoma is a group of eye conditions that damage the optic nerve, often due to high pressure in the eye. Hereditary adult type 1A glaucoma has a genetic component٫ specifically a mutation in a particular gene. It is an adult-onset disease٫ typically manifesting later in life.
Glaucoma is progressive and can lead to irreversible vision loss. The main form of glaucoma is open-angle glaucoma, where the drainage angle for fluid within the eye remains open but becomes less efficient. This leads to an increase in intraocular pressure, damaging the optic nerve over time.
Another type is closed-angle glaucoma, where the drainage angle gets blocked, causing a sudden rise in eye pressure. This requires immediate medical attention to prevent vision loss. Individuals with a family history of glaucoma are at a higher risk of developing the condition due to genetic factors.
Regular eye exams are crucial for early detection and treatment of glaucoma. Asymptomatic in its early stages, glaucoma can progress unnoticed until significant damage occurs. Treatment options aim to lower intraocular pressure to prevent further optic nerve damage and preserve vision.
