CONCLUSIONS Agitation of the syringe promotes the release of silicone oil. It is recommended to improve the technique of injection and the manufacture of specific syringes for ophthalmological use.Optical coherence tomography angiography (OCTA) is a revolutionary method in the visualization of the vascular system in different retinal and choroidal layers. During the last 4 years since the commercial availability of different OCTA devices, attempts have been made to utilize this technology in various aspects of ocular oncology from the differentiation of benign and malignant lesions to assisting in evaluation of post-treatment complications, such as radiation retinopathy. However, current OCTA technology is restricted by various artefacts and inherent limitations, some of which are more pronounced in the presence of elevated tumoural lesions. Imminent advancements in OCTA systems and image acquisition processes promise a great potential for application of OCTA in ocular oncology.PURPOSE To evaluate the changes in the corneal endothelial cell parameters and macular thickness after intraocular application of epinephrine [Formula see text] and epinephrine[Formula see text]. METHODS In this study, 210 eyes from 210 patients with age-related cataracts who underwent uncomplicated surgery were included. For all patients, specular microscopy of the corneal endothelium and macular OCT were performed before surgery and 3 months after the surgery. Patients were divided randomly into three groups without drug (control group), epinephrine [Formula see text], and epinephrine[Formula see text]. Three months after the surgery, specular microscopy of the cornea and macular OCT measurements were performed. Measurements were compared between the three groups. Postoperative measurements were
