SOLIS ALFONSO, Lesly; FUMERO GONZALEZ, Francisco Y.  e  PILOTO DIAZ, Ibraín. Primary open angle glaucoma and atherosclerotic risk factors: orbital echo-Doppler findings. Rev Cubana Oftalmol [online]. 2021, vol.34, n.3, e1025.  Epub 22-Nov-2021. ISSN 0864-2176.

Objective:

Determine the orbital echo-Doppler findings in patients with primary open angle glaucoma according to atherosclerotic risk factors.

Methods:

A cross-sectional observational descriptive study was conducted of 300 orbits of 150 patients diagnosed with primary open angle glaucoma. All the cases underwent dynamic contour tonometry and optical coherence tomography. Interrogation and clinical laboratory testing led to identification of the following atherosclerotic risk factors: arterial hypertension, smoking, diabetes mellitus type 2, dyslipidemia, obesity and excessive alcohol consumption. Orbital and carotid Doppler ultrasounds were performed, and only if they were normal they would be followed by echo-Doppler evaluation of the ophthalmic, central retinal and posterior temporal ciliary arteries.

Results:

Mean age of the study subjects was 62.3 years. 55.3% were female and 47.3% had white skin. The number of risk factors showed a moderate, positive and significant linear correlation with the resistive index, and a negative correlation with the velocities. All the risk factors expressed harmful effects on ocular flow hemodynamics, intraocular pressure and the thickness of temporal neuroretinal fibers. After adjusting for age, this negative influence continued to be relevant in most cases.

Conclusions:

The vascular aspects of glaucoma should be incorporated into the clinical management of this condition. This will make the approach more thorough and help achieve a better diagnosis.
