TO MEASURE CHOROIDAL THICKNESS USING HEIDELBERG OCT METHOD, IN A GROUP OF PATIENTS WITH SYSTEMIC ARTERIAL HYPERTENSION, AND COMPARE SUCH RESULTS WITH MEASUREMENTS OBTAINED SIMILARLY IN PATIENTS WITHOUT SYSTEMIC OR EYE DISEASES, DESCRIBED IN PUBLISHED OPHTHALMOLOGIC LITERATURE.
PATIENTS WITH SYSTEMIC ARTERIAL HYPERTENSION WHO ARE ACCOMPANIED IN THE SERVICE OF CARDIOLOGY AND NEFROLOGY, AT THE HOSPITAL OF CLINICS IN BELEM-PA, WERE REFFERED TO BE ATTENDED IN THE DEPARTMENT OF OPHTHALMOLOGY, IN THE HOSPITAL BETTINA FERRO DE SOUZA, AT FEDERAL UNIVERSITY OF PARA (BELEM- PA/ BRASIL). AFTER PRIMARY AND COMPLETE EVALUATION ( VISUAL ACUITY, REFRACTION, BIOMICROSCOPY, FUNDOSCOPY), THE PATIENTS WERE SUBMITTED TO OCT (HEIDELBERG) EXAMINATION TO EVALUATE CHOROIDAL THICKNESS ( ENHACED DEPHT MEASUREMENT), WITH 5 MAIN MEASUREMENTS ( 1 FOVEAL, 2 NASAL AND 2 TEMPORALS), IN MICROMETERS (μm) AS UNIT OF MEASUREMENT.
The data was obtained from 14 patients (in micrometer- μm). The average values, with 2 measurements from temporal region, 1 subfoveal and 2 taken nasally, with intervals of 5 μm in-between, were (respectively): 275, 281, 301, 276, 263 ( right eyes); 252, 259, 276, 254, 250 (left eyes).The average best corrected visual acuity, measured before examination with OCT, was 20/40 (Snellen Test), varying from 20/25 to 20/100. Biomicroscopy examination did not show other diagnostics than nuclear cataract in degrees I or II and six patients had been submitted to cataract surgery previously in one or both eyes. Examination of intra-ocular pressure and fundoscopy did not show any abnormalities.
The choroidal thickness values showed greater values in the subfoveal region and thinnest measurements for temporal and nasal regions. Such values do not have statistical relevance, since the amount of patients evaluated will increase accordingly with the development of research. These datas did not show difference from the ones obtained in normal patients, published previously in ophthalmologic literature. It was not found any previous paper in ophthalmologic literature that related measurements of choroidal thickness with visual acuity findings.
