ABSTRACT

Introduction: glaucoma is one of the most prevalent nosological entities and one of the main causes of blindness in the developed world. Intraocular pressure (IOP) is the only treatable risk factor and is associated with the presence and progression of the disease.
Objective: to evaluate the possible relationship between central corneal thickness and intraocular pressure.
Methods: a descriptive and prospective study was conducted between June 2009 and March 2011 in the Ophthalmology Service of "Hermanos Ameijeiras"Hospital. An ophthalmologic exam was performed to all the patients under study. Measurement of intraocular pressure was performed by the researcher using the Goldmann tonometer and central corneal thickness measurement was obtained with the Ultrasound Pachymeter (UP-1000); in both cases the average of 3 measurements was considered. Variables were analyzed using absolute numbers, percentages and averages.
Results: 184 eyes were evaluated. The female sex predominated (n=59) with a mean age of 56, 9 (SD=12.1). The average central corneal thickness was 542.91 microns, (SD=39.03). An average intraocular pressure of 16.63 mmHg (SD=2.76) by Goldmann tonometer was registered. The largest number of cases with the diagnosis of suspected glaucoma and primary open-angle glaucoma presented a minimum corneal thickness whereas in the cases of ocular hypertension, the majority of them, presented thick corneas.
Conclusions: the measurement of central corneal thickness with ultrasound pachymetry is very useful because it determines the interpretation of intraocular pressure. Its usefulness is not limited only to the selection of patients and the diagnosis, but also allows evaluating the follow-up, the response to the treatment and improves clinical results and prognosis.
