How does trauma cause glaucoma?

How does trauma cause glaucoma?

In some cases, the damaged drainage canals in the eye can build up excess scarring. This scarring blocks fluid flow and can lead to glaucoma. This type of glaucoma, called angle recession glaucoma, can occur many years after the initial injury.

Can a spinal tap cause blindness?

Cerebrospinal fluid is the fluid that bathes the brain and spinal cord. IIH (also known as Pseudotumor Cerebri) is a condition of elevated cerebrospinal fluid pressure in the absence of a mass in the brain. If untreated, IIH can cause visual loss and even blindness.

What is a traumatic spinal tap?

Background. “Bloody tap” and “traumatic tap” are both terms that have been used whenever accidental trauma is caused to a blood vessel during a lumbar puncture (LP).

What are the contraindications of lumbar puncture?

Contraindications. Absolute contraindications for performing a LP include infected skin over the puncture site, increased intracranial pressure (ICP) from any space-occupying lesion (mass, abscess), and trauma or mass to lumbar vertebrae.

Can glaucoma be temporary?

Many of these secondary, injury-related glaucoma situations are temporary and quiet down without need for long-term treatment. Some, however, become threats to vision and require long-term treatment. Various conditions cause inflammation in the eye and increase eye pressure (inflammatory glaucoma).

How can you tell the difference between SAH and traumatic tap?

A potentially more reliable method of differentiating SAH from a traumatic LP is to spin down the CSF and examine the supernatant fluid for the presence of xanthochromia, a pink or yellow coloration of the CSF supernatant caused by the breakdown of RBCs and subsequent release of heme pigments.

When should you avoid a lumbar puncture?

Avoid lumbar puncture in patients in whom the disease process has progressed to the neurologic findings associated with impending cerebral herniation (ie, deteriorating level of consciousness and brainstem signs that include pupillary changes, posturing, irregular respirations, and very recent seizure)

What can be done about traumatic glaucoma in the eye?

Treatments can include medications that reduce fluid production in the eye, laser surgery or filtering surgery. Traumatic glaucoma can also be caused by penetrating injuries to the eye, such as those caused by a sharp instrument or flying debris. The eye pressure is usually lower right after the injury occurs.

How is glaucoma caused by a penetrating injury?

Short term rises in eye pressure are controlled in ways similar to cases of blunt trauma. However, damaged tissue and scarring from a penetrating eye injury can lead to blocked drainage canals. Glaucoma due to a penetrating eye injury is best treated by preventive measures when the initial wound occurs.

Are there any other entities of post traumatic glaucoma?

Other entities of post traumatic glaucoma include post chemical, thermal, electric and radiation injury. There are many etiologies for increased IOP in traumatic glaucoma due to the pathophysiology and healing responses that occur after injury to the eye.

Can a damaged drainage canal lead to glaucoma?

In some cases, the damaged drainage canals in the eye can build up excess scarring. This scarring blocks fluid flow and can lead to glaucoma. This type of glaucoma, called angle recession glaucoma, can occur many years after the initial injury.
