- Abstract
Objective: To evaluate the macula and optic nerve microvascular structure by optical coherence tomography angiography in patients with systemic arterial hypertension. Material and Method: The study was planned cross-sectional retrospectively. Group 1 consisted of 26 patients without any health problems, group 2 consisted of 26 patients with systemic arterial hypertension longer than 5 years and less than 10 years. All of the patients included in the study were women. Macula and optic disc vascular structures were evaluated with optical coherence tomography angiography. The macula was evaluated with 6×6 mm image sections and the optic disc with 4.5×4.5 mm sections. Both superficial and deep parafoveal and perifoveal capillary vascular density in macular sections and peripapillary capillary vascular density in optic disc sections were evaluated. Results: All optical coherence tomography angiography parameters were significantly lower in hypertensive patients. In the parafoveal region, superficial capillary vascular density was 56.4±1.4% in group 1, was 54.2±2% in group 2 (p <0.001), deep capillary vascular density was 61.8±3.1% in group 1, 59.4±1.5 was in group 2 (p= 0.004). In the perifoveal region, superficial capillary vascular density was 55.2±0.9% in group 1, was 53.3±1.9% in group2 (p <0.001), deep capillary vascular density was 62.4±3.5% in group 1, was 60±2.9% in group 2 (p=0.01). Peripapillary capillary vascular density was 53±1.8% in group 1, and 50.6±1.4% in group 2 (p= 0.007). Conclusion: In patients with systemic arterial hypertension for more than five years, both the superficial and deep vascular structures feeding the inner retinal layers in macula and the peripapillary vascular layer had significantly lost microvascular structures compared to healthy individuals. Optical coherence tomography angiography may have a potential role in detecting early retinal microvascular changes in hypertension patients.
