A choked disc, also known as a swollen optic disc or papilledema, refers to a medical condition characterized by increased swelling and congestion of the optic nerve, which results in an elevation of the optic disc. The optic disc is the part of the eye where the optic nerve enters, and it appears similar to a round, pale spot on the retina.
This condition is typically caused by an increase in intracranial pressure, meaning that there is an elevated pressure within the skull. This elevated pressure can occur due to various factors, such as a brain tumor, meningitis, brain abscess, or hydrocephalus. Choked disc can also be a result of conditions that impair the drainage of cerebrospinal fluid or lead to increased production of cerebrospinal fluid.
The primary symptom associated with choked disc is swelling and edema of the optic disc, which may be detected during an eye examination. Other symptoms include blurred vision, headaches, visual disturbances, and occasionally, double vision. The severity of symptoms depends on the underlying cause and the extent of the optic nerve involvement.
Timely diagnosis and treatment of the underlying cause of choked disc are crucial to prevent potential vision loss and further complications. Treatment focuses on managing the underlying condition responsible for increased intracranial pressure. It may involve medication to reduce swelling, surgical intervention to relieve pressure, or other interventions specific to the underlying cause.
Regular monitoring of the optic disc and close follow-up with healthcare professionals are vital to prevent long-term visual impairment often associated with choked disc.
