PURPOSE To determine feasibility of optic nerve head (ONH) imaging and to characterize ONH development in full-term infants without sedation using handheld spectral-domain optical coherence tomography (SD OCT). DESIGN Prospective cross-sectional study. PARTICIPANTS Three hundred fifty-two children aged between 1 day and 13 years. METHODS All(More)
PURPOSE To characterize the time course of normal foveal development in vivo in term infants and young children using handheld spectral-domain optical coherence tomography (HH-SDOCT). METHODS We obtained 534 HH-SDOCT scans from 261 infants, children, and young adults with a mean age of 4.9 years (range, 0-27 years). Each retinal layer was manually(More)
BACKGROUND Retinal development normally involves migration of the inner retinal layers away from the fovea, migration of the cone photoreceptors into the fovea, and elongation of the photoreceptors over time. This process is arrested prematurely in albinism. However, because retinal development continues at least until the age of 4 years, when development(More)
Participants were graded into one of seven categories: (0) Continuous ISe, (1) ISe intensity reduction, (2) ISe disruption with no visible HRZ, (3) ISe disruption with HRZ intersecting with the ISE, (4) ISe disruption with HRZ causing displacement of the ISe (white arrows), (5) ISe disruption with HRZ causing displacement of the ELM (white arrow), (6) ISe(More)
