Summary
This study aimed to assess the correlation between visual field changes and optical coherence tomography (OCT) angiography changes of retinal nerve fiber layer in patients with primary open angle glaucoma.
Detailed description
Glaucoma is the leading cause of irreversible blindness worldwide. Since glaucomatous damage is preventable but irreversible, an early diagnosis and close follow-up of glaucoma patients are primordial. Optical coherence tomography angiography (OCTA) is a recently developed, noninvasive imaging modality that detects blood flow through the motion contrast generated by red blood cells. Currently, there are 2 groups of complementary exams used for the diagnosis and follow-up of glaucoma patients: structural (where OCT has a considerable role) and functional (visual field) optic nerve measurements, Both technologies have strengths and limitations. A new technology for diagnosis and follow-up that can avoid the limitations summarized above is lacking. OCTA seems to be a good candidate for such a role, OCT can detect the Doppler frequency shift of the backscattered light that provides information on blood flow.
