PAREJA-ESTEBAN, J. et al. Morphological macular changes after cataract surgery: risk factors. Arch Soc Esp Oftalmol [online]. 2009, vol.84, n.12, pp.605-609. ISSN 0365-6691.

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) µm3; 0.16 (SD0.02) µm3 and 204.97 (SD29.79) µm. One month after surgery the measurements were TMV: 6.93 (SD0.56) µm3; FOVOL: 0.17 (SD0.06) µm3 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. Conclusions: We found a sub-morphological macular oedema one month after uncomplicated cataract surgery, with age being a risk factor for developing a greater increase in TMV. Arterial hypertension does not seem to be a risk factor for these changes.
