: The procedures performed in this study were in accordance with the ethical standards of the institutional and/or national research committee and with the 1964 Helsinki declaration and its later amendments or comparable ethical standards and approved by the Ethics Committee Of The Eye Subspecialty Center (ESC),18 El Khalifa El Maamoun Street, Heliopolis, 11402 Cairo, Egypt. The ESC Ethics Committee approved the use of verbal-only consent to participate in the study because (1) All the data in the study were collected through performing Spectral-Domain Optical Coherence Tomography (SD-OCT), which is a noninvasive imaging technique used for medical imaging, employed in clinical practice and does not require written consent, it uses light waves to take cross-section pictures of the retina). (2) The procedure was performed with no sedation or anesthesia, and no topical eye drops were instilled for corneal anesthesia or dilatation of the pupil before the test. (3) The possibility of discomfort expected in the study is not greater than those ordinarily happened during the performance of the routine ocular examination. For obtaining the informed verbal consent, the investigator reads and explains a verbal version of consent from an information sheet which includes most of the elements of a consent form (purpose, the procedure, and its duration, any risk of discomfort, benefits, the confidentiality of records, etc). All subjects were allowed to ask questions before giving their verbal consent.
