Importance: Binocular indirect ophthalmoscopy (BIO) examination for retinopathy of prematurity (ROP) is a well-known cause of repeated preterm infant stress.
Objective: To compare stress during investigational optical coherence tomography (OCT) imaging to that during BIO for ROP.
Design, Setting, And Participants: This cross-sectional study examined infants at the bedside in the intensive care nursery. Consecutive preterm infants enrolled in Study of Eye Imaging in Preterm Infants (BabySTEPS) who had any research OCT imaging as part of the study. Patients were recruited from June to November 2019, and analysis began April 2020.
Main Outcomes And Measures: Infant stress was measured using modified components of a neonatal pain assessment tool before (baseline) and during OCT imaging and BIO examination of each eye.
Results: For 71 eye examinations of 16 infants (mean [SD] gestational age, 27 [3] weeks; birth weight, 869 [277] g), change from baseline to each eye examination was lower during OCT imaging than during BIO and the difference between OCT imaging and BIO at each eye examination was significant for the following: infant cry score (first eye examination: mean [SD], 0.03 [0.3] vs 1.68 [1.2]; -1.65 [95% CI, -1.91 to -1.39]; second eye examination: mean [SD], 0.1 [0.3] vs 1.97 [1.2]; -1.87 [95% CI, -2.19 to -1.54]), facial expression (first eye: 3 [4%] vs 59 [83%]; -79% [95% CI, -87% to -72%]; second eye: 4 [6%] vs 61 [88%]; -83% [95% CI, -89% to -76%]), and heart rate (first eye: mean [SD], -7 [16] vs 13 [18]; -20 [95% CI, -26 to -14]); second eye: mean [SD], -3 [18] vs 20 [20] beats per minute; -23 [95% CI, -29 to -18]) (P < .001 for all). Change in respiratory rate and oxygen saturation did not differ between OCT imaging and BIO.
Conclusions And Relevance: While the role of OCT alone or in combination with BIO is currently unknown for ROP, these findings suggest that investigational OCT imaging of ROP is less stressful than BIO examination by a trained ophthalmologist.

Artificial Intelligence for Optical Coherence Tomography in Glaucoma.
Transl Vis Sci Technol
January 2025
Glaucoma Service, Wills Eye Hospital, Philadelphia, PA, USA.
Purpose: The integration of artificial intelligence (AI), particularly deep learning (DL), with optical coherence tomography (OCT) offers significant opportunities in the diagnosis and management of glaucoma. This article explores the application of various DL models in enhancing OCT capabilities and addresses the challenges associated with their clinical implementation.
Methods: A review of articles utilizing DL models was conducted, including convolutional neural networks (CNNs), recurrent neural networks (RNNs), generative adversarial networks (GANs), autoencoders, and large language models (LLMs).
Preferential Sites of Retinal Capillary Occlusion in Sickle Cell Disease.

Department of Ophthalmology, New York Eye and Ear Infirmary of Mount Sinai, New York, New York, United States.
Purpose: To assess the preferential sites of retinal capillary occlusion at the parafovea in patients with sickle cell disease (SCD) using optical coherence tomography angiography (OCT-A).
Methods: OCT-A scans from 107 patients with SCD and 51 race-matched unaffected controls were obtained using a commercial spectral domain-OCT system. At least eight sequential 3 × 3 mm scans centered at the fovea were acquired and averaged for image analysis.
Effect of Different Treatments on Retinal Thickness Changes in Patients With Multiple Sclerosis: A Review.
CNS Neurosci Ther
January 2025
Department of Neurology, Isfahan University of Medical Sciences, Isfahan, Iran.
Background: Multiple sclerosis (MS) is an autoimmune disorder affecting the central nervous system, with varying clinical manifestations such as optic neuritis, sensory disturbances, and brainstem syndromes. Disease progression is monitored through methods like MRI scans, disability scales, and optical coherence tomography (OCT), which can detect retinal thinning, even in the absence of optic neuritis. MS progression involves neurodegeneration, particularly trans-synaptic degeneration, which extends beyond the initial injury site.

Purpose: To characterize the anterior segment (AS) morphology of patients with long-term silicone oil (SiO) in situ (> 12 months) following pars plana vitrectomy (PPV).
Methods: This prospective, comparative characterization study was conducted between January 2022 and July 2023. Patients were included and sorted based on if they had undergone PPV without long-term SiO or had SiO in situ for at least 12 months at the time of review and image collection.
Far Cortical Locking Versus Standard Constructs for Locked Plate Fixation in the Treatment of Acute, Displaced Fractures of the Distal Femur: A Multicenter Randomized Trial.
J Bone Joint Surg Am
October 2024
Department of Orthopaedics, Faculty of Medicine, University of British Columbia, Vancouver, British Columbia, Canada.
Background: Fixation of distal femoral fractures remains a challenge, and nonunions are common with standard constructs. Far cortical locking (FCL) constructs have been purported to lead to improved fracture-healing as compared with that achieved with traditional locking bridge plates. We sought to test this hypothesis in a comparative effectiveness clinical trial.
