ABSTRACT

Purpose: To evaluate the rate of patients that requires adjustment of intraocular pressure (IOP) depending on central corneal thickness (CCT). Material y methods: We include patients 18 years old or more, with complete ophthalmologic evaluation, we exclude the eyes with corneal diseases that affect the measurements, visual acuity ‹20/400, or any disease that difficult the central fixation of the eye. Results: We evaluated 200 eyes, 18-86 years (average 56.52, D.E.±13.89); 22 male (22%); divided in 3 groups: open angle glaucoma (OAG) 142 eyes (71%); ocular hypertension 28 eyes (28%) and glaucoma suspect 30 eyes (30%). The average of CCT was 560.4 μ, ranked of 393 a 707 μ (D.E.±41.59). By Goldmann tonometry, the average of IOP was 15.49 mmHg (ranked 10-26mmHg D.E.±2.95). Thirty one eyes have CCT less than 520 μ (15.5%, C.I. 95% 12.2 to 22.8), 110 have CCT between 520 y 580 μ (55%) and 59 have CCT more than 580 μ (29.5% C.I. 95% 23.6 to 3.4) Conclusions: The rate of patients that need to adj ust the IOP by modifications in the CCT is nearly 50%, this is important for massive detections and in the first level of attention.
