![]() ![]() In total, 25 hospital ophthalmologists were invited to participate. Study design and participants: Initially, a cross-sectional study was conducted in which an online self-administered questionnaire from SurveryXact with open- and close-ended questions was constructed. However, correction software still represents a significant interpretation challenge. Current OCT-A devices use their own algorithm to reduce artefacts in the imaging process. OCT-A instrument manufacturers employ a unique algorithm and scanning protocol to acquire images of blood vessels. A recent and adopted neovascularisation imaging method is the non-invasive image-device optical coherence tomography angiography (OCT-A). An increased risk was recorded of allergy, nausea, vomiting, urticaria and - in severe cases - anaphylaxis due to the injection of fluorescein dye. This procedure is the current imaging gold standard. To confirm clinical suspicion of neovascular AMD (nAMD), the invasive procedure of fundus fluorescein angiography (FFA)/indocyanine green angiography (ICGA), is performed. A structural optical coherence tomography (OCT) can only confirm and monitor fluid in the retina. AMD may be divided into dry and wet AMD the latter is characterised by retinal neovascular complications that may lead to leakage of either intra- or subretinal fluid, haemorrhage and scarring of the retina, resulting in loss of vision. AMD involves macular structure and function deterioration with distinguishable findings that become evident when patients exceed 55 years of age. Age-related macular degeneration (AMD) affects the retina, is a leading cause of irreversible visual impairment and causes approximately 9% of all blindness worldwide.
