Angle-closure glaucoma:

This serious condition known as “Acute angle closure glaucoma” makes the pressure inside your eye go up out of nowhere. It can ascend within merely hours. It happens when fluid in your eye can't deplete the manner in which it ought to. It isn't just about as regular as different kinds of glaucoma, which cause pressure development substantially more gradually over time. Acute angle-closure glaucoma is brought about by a fast or abrupt expansion in pressure inside the eye.

Causes Of Glaucoma

Fluid depletes out of your eye through a system of channels. These channels live in a lattice of tissue between your iris and your cornea .

At the point when your iris and cornea draw nearer together, it "shuts the angle" between them. At the point when this happens abruptly, it's called an acute assault and is excruciating.

Acute angle closure glaucoma totally hinders your trenches. It prevents fluid from moving through them, sort of like a piece of paper sliding over a sink channel. The pressure that develops can harm your optic nerve. On the off chance that you don't treat the issue rapidly enough, you could lose your sight totally.

They please rapidly. You will not have the option to overlook them. They include:

  • Eye torment
  • Severe migraine
  • Queasiness or spewing
  • Blurry or murky vision
  • Seeing rainbows around lights
  • Redness in the white piece of the influenced eye
  • Understudies of various sizes
  • Abrupt loss of sight

At the point when your PCP inspects you, they may likewise see that your understudies presently don't get more modest or greater when they sine light on them.

How Is It Diagnosed

In the event that you think you have acute angle closure glaucoma; you'll need to see an ophthalmologist immediately - it's a serious problem that requires immediate medical attention. The physician will analyze you and get some information about your symptoms. They may do at least one or more tests to discover more about what's happening inside your eye.

Angle-closure glaucoma:

This form of glaucoma occurs when the iris bulges. The bulging iris partially or completely blocks the drainage angle. As a result, fluid can't circulate through the eye and pressure increases. Angle-closure glaucoma may occur suddenly or gradually.


Angle-closure glaucoma might be caused by: 

  • The angle between the iris and the cornea becomes narrow, blocking the normal flow of fluid out of the eye.
  • Older individuals are more prone to developing angle closure glaucoma.
  • There is a genetic component to the development of angle closure glaucoma.
  • People of Asian, Inuit, or Native American descent have a higher risk.
  • Individuals with hypermetropia have a smaller anterior chamber, increasing the likelihood of angle closure.
  • Some medications can induce angle closure glaucoma as a side effect.
  • Enlarged pupils can trigger angle closure in susceptible individuals.
  • Inflammatory conditions or eye injuries can lead to angle closure glaucoma.


The following are signs of intermittent angle closure:

  • Blurry or unfocused field of vision
  • Difficulty adjusting to dark rooms
  • Recurring mild pain around or in eyes
  • Recurrent headaches
  • Seeing colorful rings or halos around lights
  • The following are signs of an angle closure attack:
  • Red painful eye
  • Sudden blurring or loss of vision
  • Severe headache
  • Excessive tearing or watering
  • Sudden nausea or vomiting


Following tests, exams, labs etc are conducted to diagnose Angle-closure glaucoma:

Eye examination

A comprehensive examination, including measurement of intraocular pressure (tonometry), assessment of the anterior chamber angle (gonioscopy), evaluation of the optic nerve, and visual field testing, is performed.

Symptoms assessment

The presence of symptoms such as severe eye pain, headache, blurred vision, halos around lights, and nausea or vomiting is evaluated.

Imaging tests

Imaging techniques like optical coherence tomography (OCT) and ultrasound biomicroscopy (UBM) may be used to assess the structures of the eye, including the angle and the drainage system.

Measurement of intraocular pressure

Increased intraocular pressure is often observed in angle closure glaucoma and can be measured using various methods such as applanation tonometry or non-contact tonometry.

Evaluation of optic nerve damage

Examination of the optic nerve head is crucial to assess any signs of damage or changes associated with glaucoma.


This procedure allows visualization and assessment of the angle between the iris and the cornea to determine if it is open or closed.

Visual field testing

Assessment of the patient's peripheral vision is performed to identify any visual field defects that may indicate glaucomatous damage.
