What is Pathology - Acute Angle-Closure
Asian or Inuit women over 45 or people who are nearsighted constitute the highest risk category. The anterior chamber has issues with fluid and pressure discharge when glaucoma is present.
• Causes the outflow region of the iris/corneal angle to narrow due to bunching of the iris as the pupil dilates because the eye is an enclosed fibrous capsule, making it impossible for the eye to swell without putting pressure on crucial structures like the choroid retina and optic nerve. A moderate or urgent episode may be brought on by persistent pupil dilation. Sleep and relaxation can help with a mild attack. The same kinds of signs that cause a medical and surgical emergency can also result from trauma to the eye.
Findings from the Evaluation and Diagnosis
• Tonometry used to calculate IOP. During an eye test, a gonioscopy is used to see and measure the angle of the anterior chamber.
Blindness, either complete or partial.
• The overall impact of ocular drops.
• Infection after surgery.
Treatment through surgery and medicine
• Prophylactic laser surgery can be performed on the eye that is not affected to make an opening between the anterior and posterior chambers.
• Beta-adrenergic blockers, carbonic anhydrase inhibitors, adrenergic agonists, or miotic drugs.
• Corticosteroids to decrease inflammation, osmotic diuretics, analgesics, antiemetics, and bed rest are used in acute episodes.
• Steer clear of prolonged times of darkness, stress, and any medications that could cause mydriasis.
Assess for eye redness, vertigo, vomiting, and the presence of rainbows around objects; this is a medical and surgical emergency. Time is the goal.
