What is ocular hypertension?

Ocular hypertension, or increase in intraocular pressure, is a process that need not necessarily be synonymous with glaucoma, a disorder in which there is damage to the optic nerve and for which ocular hypertension is the main risk factor.

Levels of eye pressure

Eye pressure varies from person to person, and there is no precise normal figure. In some patients, eye pressure is at the higher end of what we consider reasonable for the general population, without this “borderline pressure” causing any functional or structural damage to vision or the optic nerve.


Es en estos pacientes en los que apreciamos una discreta hipertensión ocular sin alteración en el resto de la exploración clínica o pruebas complementarias, en los que se precisa de un minucioso estudio continuado mediante la realización entre otros, de tomografía óptica computerizada (OCT) que nos permite evaluar las diferentes capas de la retina y nervio óptico, y del campo visual que nos permite valorar la repercusión clínica o funcional que las alteraciones estructurales visibles en la OCT tienen sobre la visión del paciente.


Depending on each individual case, patients can opt to use antiglaucoma agents (drops) or simply monitor it closely as not all cases of ocular hypertension will stem from glaucoma and those that do need to be detected as early as possible, even before symptoms appear. As such, state-of-the-art equipment is needed, enabling us to detect miniscule changes in the nerve fibres so that we can act early and to prevent these abnormalities having any repercussions on the patient’s vision.


At CLÍNICA RAHHAL, we have state-of-the-art technological equipment which, combined with our teamwork, ensures the best results.

Select one of the following frequently-asked questions from our patients to display the answer. If you cannot find the answer to your question, please contact us using the form below.

Is eye pressure the same as blood pressure?

No. These refer to two different concepts. Blood pressure depends on our cardiovascular system, whereas eye pressure will depend on our eye’s ability to “filter” the liquid content inside it.

Is high eye pressure painful?

The pain resulting from raised levels will depend on whether these levels are chronically raised, in which case the eye “gets used to” this pressure and it is not usually painful, or whether they are acutely raised, i.e., suddenly. In these cases, if levels are significantly raised, this can be painful. However, in most cases the pressure is chronically raised and this increase is not very noticeable, which means the patient remains asymptomatic and ocular hypertension is detected during a routine eye examination.

Is the pressure taken with an air puff test the same as that taken with a contact test?

Although both forms are widely accepted to measure eye pressure, the air puff test is much less accurate as it is an approximation of the actual level.

Is having high pressure always negative?

An appropriate eye pressure level is generally considered to be below 21 mmHg. However, many patients with levels that are slightly higher never develop any disorders, and patients with pressure levels that are even lower may still develop eye conditions. In short, even though the maximum pressure is around 21 mmHg, everyone has pressure levels that are more or less optimal for them, and a particular level is not necessarily either normal or indicative of a disorder in different patients.

Does ocular hypertension always need to be treated?

Not in every case. What you need to do is closely monitor these cases and determine whether or not this pressure level is causing an eye disorder.

Is ocular hypertension the same as glaucoma?

Not necessarily. A pressure level that is slightly above the average limit does not entail a disorder in every patient. However, pressure levels that are considered “normal” for most people, are enough in some people to encourage the development or progress of glaucoma. Eye pressure is a risk factor for glaucoma and a thorough examination by an ophthalmologist is what should determine this so as to be able to take the appropriate treatment option if necessary.

Does my family history have any impact?

Of course. The genetic load has a very significant impact and for that reason patients with relatives who have been affected by glaucoma must be closely monitored by an ophthalmologist.
