Purpose: The authors relate posterior segment microanatomy from perinatal spectral domain optical coherence tomography to visual acuity, brain abnormalities, and neurodevelopment.
Methods: Thirteen infants (11 preterm and 2 term birth), imaged in the nursery with portable spectral domain optical coherence tomography, had visual acuity and sensorimotor testing at age 9 months to 15 months (grating acuity) or 4 years to 5 years (optotype), and medical records reviewed for brain magnetic resonance imaging reports and Bayley scales testing at age 18 months to 24 months.
Results: Eight children with age-appropriate macular microanatomy without edema on perinatal spectral domain optical coherence tomography had optimal (≥ 20/40) or within normal limits (grating acuity) visual acuity. Five children with perinatal macular edema had suboptimal visual acuity (in 9/10 eyes) and sensorimotor deficits, magnetic resonance imaging abnormalities, or poor neurodevelopment. Macular edema persisted in 1 infant through 9-month corrected age.
Conclusion: Maturation of the visual system and evolution of retinal anomalies can be monitored with posterior segment spectral domain optical coherence tomography. Retinal microanatomy observed in infancy might relate to subsequent vision and other central nervous system events, but additional studies are needed to determine the range of normal microanatomy in infants and how this relates to vision and neurodevelopment.

Background: To evaluate the ganglion cell complex thickness in patients taking oral hydroxychloroquine.
Methods: In this hospital-based, cross-sectional, non-interventional, comparative study, 87 eyes of 87 patients taking hydroxychloroquine were recruited. All the patients underwent complete ophthalmological evaluation along with dilated fundus examination.

An ongoing goal of top-down mass spectrometry is to increase the performance for larger proteins. Using higher energy activation methods, like 193 nm ultraviolet photodissociation (UVPD), offers the potential to cause more extensive fragmentation of large proteins and thereby yield greater sequence coverage. Obtaining high sequence coverage requires confident identification and assignment of fragment ions, and this process is hampered by spectral congestion and low signal-to-noise ratio (S/N) of the fragment ions.

Congenital hearing loss is a significant health problem, with a worldwide incidence of >6 per 1000 live births. Late diagnosis will delay appropriate treatment, leading to potential neurodevelopment problems. Early diagnosis requires neonatal hearing screening, where one of the most used techniques is automated Auditory Brainstem Responses (aABR).

Purpose: To evaluate inter-grader variability in posterior vitreous detachment (PVD) classification in patients with epiretinal membrane (ERM) and macular hole (MH) on spectral-domain optical coherence tomography (SD-OCT) and identify challenges in defining a reliable ground truth for artificial intelligence (AI)-based tools.
Methods: A total of 437 horizontal SD-OCT B-scans were retrospectively selected and independently annotated by six experienced ophthalmologists adopting four categories: 'full PVD', 'partial PVD', 'no PVD', and 'ungradable'. Inter-grader agreement was assessed using pairwise Cohen's kappa scores.

Purpose: To characterize a no b-wave (nob) mouse model of congenital stationary night blindness (CSNB) caused by a Grm6 variant that disrupts photoreceptor-to-bipolar cell signaling. Additionally, we aim to evaluate the efficacy of gene therapy in restoring visual function.
Methods: The nob mouse was generated through selective breeding to regenerate the nob phenotype.
