Corneal imaging is important for the diagnostic and therapeutic evaluation of many eye diseases. Optical coherence tomography (OCT) is extensively used in ocular imaging due to its non-invasive and high-resolution volumetric imaging characteristics. Optical coherence microscopy (OCM) is a technical variation of OCT that can image the cornea with cellular resolution. Here, we demonstrate a blue-light OCM as a low-cost and easily reproducible system to visualize corneal cellular structures such as epithelial cells, endothelial cells, keratocytes, and collagen bundles within stromal lamellae. Our blue-light OCM system achieved an axial resolution of 12 µm in tissue over a 1.2 mm imaging depth, and a lateral resolution of 1.6 µm over a field of view of 750 µm × 750 µm.

A 4-year-old girl presented with an enlarging, congenital, intrascleral cyst of the left eye. Intraoperative anterior segment optical coherence tomography was used to visualize and to assess the extent of the cyst, facilitating safe excision. The cyst was completely removed, and the defect was covered with an amniotic membrane graft, with a good outcome.

Objective: To describe the anatomical and functional outcome of autologous internal limiting membrane (ILM) transplant with 27-gauge plus (27G+) three ports pars plana vitrectomy (PPV) in failed and recurrent full-thickness macular holes (MH) in a spectrum of pathologies.

Study Design: Observational cohort study Methods: Seven eyes of seven patients who had failed or recurrent MH were included from January 2017 to January 2022. A single vitreoretinal surgeon performed all surgeries using a 27G+ PPV system in a tertiary care hospital.

Significance: Stroke is the leading cause of chronic disability in the United States. How stroke size affects post-stroke repair and recovery is poorly understood.

Aim: We aim to investigate the effects of stroke size on early repair patterns and determine how early changes in neuronal circuits and networks predict functional outcomes after stroke.

"The eyes are a window to the brain," prompting the investigation of whether retinal biomarkers can indicate Alzheimer disease (AD) and cognitive impairment. AD is a neurodegenerative condition with a lengthy preclinical phase where pathologic changes in the central nervous system (CNS) occur before clinical symptoms. Mild cognitive impairment (MCI) often precedes AD.
