All About the Tests to Diagnose Glaucoma

Diagnose Glaucoma is a disease that can remain unnoticeable until a person starts losing vision. Even the person who might seem to have a perfect idea might have Glaucoma. The reason why it is not easily detectable is that its symptoms are not noticeable. The doctors recommend that a person get annual eye checkups to find anything unnoticeable before any damage.

Doctors consider several factors while diagnosing this disease, such as family history, optic nerve status, corneal thickness, etc. And after all that, they need to perform some tests to ensure you have Glaucoma.

Here we have brought you a list of all the tests performed to diagnose Glaucoma.


There are various types of tonometry, which is a test to quantify eye pressure. In any standard eye test, your eye care physician will test eye pressure and do a test to take a gander at the optic nerve. That is because raised eye pressure is the thing that generally tips eye specialists off to possible Glaucoma.
The most exact approach to quantify eye pressure is after getting desensitizing eye drops. Therefore, your primary care physician will have you place your head on the cut light and gaze directly ahead. In contrast, the specialist moves the tip of the gadget to contact your cornea. The gadget will gauge how much is the need for power to straighten the cornea, delivering a reading.
The subsequent technique is the same as the first. However, it utilizes a handheld pencil-formed gadget to quantify the crucial factor rather than the connection on the cut light. The third technique is known as the air puff. It uses a light emission and a genuine puff to check how much is the need for pneumatic stress to level the cornea. The air puff is the most awkward of the three since the eye is generally not desensitized. On the off chance that your eye pressure is high from any of these tests. Your primary care physician will then, at that point, accomplish more definitive tests to analyze Glaucoma.


Ophthalmoscopy is one of the tests conducted usually during eye examinations. This test allows your primary care physician to see the rear of your eye and ensure normal veins, retina, and optic nerve function. There are a couple of kinds of ophthalmoscopy tests, some of which require eye drops to widen your eyes. However, it implies your pupil dilates so your primary care physician can improve the look inside your eye. Then, at that point, contingent upon the technique, your PCP will utilize a type of light shaft and hold a focal point up to your eye to get a look. You might have to lean your head against a cut light. Else, your PCP might wear a light on their head and hold the focal point up with their hands.


This test is utilized to check if the eye’s drainage angle is open or shut. This close gander at the drainage framework in the eye can give your primary care physician a standing into what sort of Diagnose glaucoma is affecting everything. In case you’re in danger of acute angle-closure Glaucoma. An unexpected and severe expansion in eye pressure warrants prompt clinical consideration. According to the Diagnose Glaucoma Research Foundation, Gonioscopy also allows your primary care physician to check for abnormal veins, attachments, harm from past eye injury, and other complexities or irregularities in the drainage system.
Before a gonioscopy, your PCP will give you eye drops to numb the eye and place a unique contact lens directly on the highest point of the eye. They will then, at that point, position your head in the cut light. So a light bar will arrive at the particular lens and make the end noticeable to your PCP. This test is fast and straightforward. It shouldn’t take more than a couple of moments to do.


Pachymetry estimates the thickness of the cornea, which is the peripheral piece of the front of the eye that covers the pupil and iris. Corneal thickness can likewise affect eye pressure tests—if the cornea is genuinely thick, it can give a bogus high pressing reading; in case it’s thin, you might get a fake low pressing task.
Pachymetry is finished utilizing a pachymeter, a little handheld test. Your PCP will give you eye drops to numb the eye first and afterward place the gadget on the front of the eye (the cornea) to quantify its thickness. The test is high-speed. Quantifying the two eyes requires a moment or less, and you shouldn’t feel a thing.

Visual Field Testing 

Otherwise called perimetry, a visual field test is to survey whether you’ve lost peripheral vision. Peripheral vision is typically the main thing to break down if you have Glaucoma. During the trial, you’ll place your head in a vault-formed gadget and gaze directly ahead at an objective while light pops up in various regions through your field of vision. You’ll click a catch at whatever point you see the light, which makes a difference in “map” your peripheral vision.
According to the Glaucoma Research Foundation, it’s expected to encounter a deferral in considering them as it moves around your blind spot. Along these lines, if you experience this during the test, do not worry.
If you are diagnosed with Glaucoma, you’ll probably need a visual field test one to two times each year to check for vision changes.

Optic Nerve Scanning

There are a couple of various advancements used to check the optic nerve and take complex pictures. In any case, ophthalmologists talk about OCT, which represents Optical Coherence Tomography, as the most exceptional technique we have now. It can give your eye specialist exact estimations of the nerve’s shape and volume and uncover any diminishing regions. Finding even the littlest measure of harm almost immediately allows you an opportunity to treat Glaucoma before it advances and results in any vision misfortune. Eye specialists acclaim this innovation for making it conceivable to distinguish changes sooner than at any other time.
If your optic nerve looks strange, your PCP might need to do standard nerve examinations at regular intervals or a year to check if things are advancing or remain stable.
The test is fast and effortless and expects you to put your face against a machine so it can snap a photo of your eye.
