CAMBIOS MORFOLÓGICOS MACULARES TRAS CIRUGÍA DE CATARATAS: FACTORES DE RIESGO MORPHOLOGICAL MACULAR CHANGES AFTER CATARACT SURGERY: RISK FACTORS

Objective: To analyze morphological macular changes after uncomplicated cataract surgery and their correlation with age and arterial hypertension. Methods: Total macular volume (TMV), foveal volume (FOVOL) and foveal thickness (FOV) in patients who had undergone cataract surgery were measured using OCT3 Stratus ® before surgery, the day after the intervention and one month later. The data were analyzed using SPSS 15.0 software. Results: The study group was composed of 114 eyes from 114 patients. The mean TMV, FOVOL and FOV in the subgroup of patients with signal strength over 6 before cataract surgery were 6.59 (SD0.67) µm 3 ; 0.16 (SD0.02) µm 3 and 204.97 (SD29.79) µm. One month after surgery the measurements were TMV: 6.93 (SD0.56) µm 3 ; FOVOL: 0.17 (SD0.06) µm 3 and FOV: 218.07 (SD87.60) µm. We found statistically significant differences (P<0.05) in TMV, but not in FOVOL or FOV. The group of patients under 74 years showed a greater increase in TMV. Patients with arterial hypertension did not show an increase in TMV or FOV compared to patients without arterial hypertension.
