The cornea is located at the front of the eye, protruding from the plane of the eyeball in front of the iris. The thickness of the cornea varies from person to person and is an important piece of information for ophthalmologists in many types of eye treatment and diseases. In all cases, pachymetry is very quick and painless.
Measuring the thickness of the cornea can provide the specialist with vital information in a number of situations.
In the case of glaucoma, for example, it is essential to measure the corneal thickness in addition to the intraocular pressure, as these two data should be evaluated together. Repeat examinations will allow changes to be monitored, which may indicate other pathologies.
Measuring corneal thickness can also be very helpful for certain medications or after eye surgery. It gives an accurate picture of the condition of the cornea and any changes that may occur.
If a difference in the thickness of the cornea is found, it is always important to clarify which layer of the cornea is affected. Other tests may be necessary, such as an OCT scan, which gives a more precise picture of the lesion. It is also important to establish what may have caused the change in the thickness of the cornea. Whether it is a side effect of a treatment, a possible new disease, or whether contact lens wear is causing the corneal swelling. It is very important to distinguish between these cases so that the practitioner can start the right course of action. Depending on this, it may be a question of changing an ongoing medication, diagnosing an emerging condition, or even changing contact lenses.
The measurement of the corneal thickness is always quick and completely painless. The optical pachymetry used at Rapidus Optica is a non-contact type of test, which can be performed using the same non-contact measurement of intraocular pressure and the above-mentioned OCT examination. In both cases, the head is placed in a chin and forehead resting device and the test is completed in a few minutes.
In some cases, a more complex vision test than the traditional tests is needed, this is the functional eye test. Comprehensive mapping, which can even be referred to as a special education examination, highlights the links between learning disabilities and vision
I deal with a lot of people who have suffered some kind of brain injury. It could be surgical, traumatic brain injury, brain tumour, or even stroke. My vocation is to make their lives better and easier through neuro-optometric rehabilitation or visual therapy.
OCT – Optical Coherence Tomography – allows us to screen the nerve membrane of the eye, as well as the optic nerve and macula, and their diseases.
Vision therapy provides solutions to vision problems caused by neurological disorders. Depending on the results previously assessed and tested, it provides a complex treatment taking into account the abnormalities and symptoms.
A CFF test to check the conduction of the optic nerve can detect several problems. These include optic nerve damage, which in most cases is caused by glaucoma.
The polatest is a special test method that can detect hidden strabismus. Because this problem can indeed remain hidden for a long time.
