This condition occurs in eyes with elevated IOP, without optic nerve damage. Due to individual characteristics that determine a decreased susceptibility to the disease, these eyes do not develop glaucoma. This may be partially explained in some cases due to an increased central corneal thickness (thick cornea), which may lead to imprecise measurement of the IOP by tonometer devices (overestimation of the IOP).
However, it is important to note that some eyes with elevated IOP may be simply at the beginning of the disease process, whereas there was not enough time to damage the optic nerve head. If this is the case, with time, glaucoma will develop.
The ophthalmologist will discuss with the patient the advantages and disadvantages of different management approaches for this condition in each case, including observation only or treatment.
In all Ocular Hypertension cases, continuous long-term follow-up are highly recommended, and some eye exams will be necessary for proper monitoring.
