Background: To evaluate the safety of different doses of subconjunctival cetuximab in rabbits.
Methods: After general anesthesia rabbits received a subconjunctival injection of 2.5 mg in 0.5 ml, 5 mg in 1 ml, and 10 mg in 2 ml of cetuximab in their right eyes (two rabbits in each group). A similar volume of normal saline solution was injected subconjunctivally in the left eyes. The histopathologic changes were evaluated after enucleation with the aid of H&E staining.
Results: No significant difference were observed between the treated and control eyes in terms of conjunctival inflammation, goblet cell density, or limbal blood vessel density for all administered doses of cetuximab.
Conclusion: Subconjunctival injection of cetuximab with the administrated doses in rabbit eyes are safe.

Background: Sjögren's syndrome (SS) is a chronic autoimmune disease delineated by excessive lymphocyte infiltration to the lacrimal or salivary glands, leading to dry eye and dry mouth. Exosomes secreted from mesenchymal stem cells (MSC) are known to have anti-inflammatory and tissue regeneration abilities. This study endeavored to demonstrate the effect of MSC-derived exosomes on the clinical parameter of dry eyes and associated pathology in SS mouse model.

To describe a case series of patients who experienced hemorrhagic complications following intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections. In a small case series of 3 patients with retinal disorders, imaging with ultrasound biomicroscopy (UBM) was performed within 1 day following anti-VEGF injection. The first patient had a mild vitreous hemorrhage, and UBM demonstrated a suspected needle track through the pars plana; the hemorrhage cleared spontaneously.

To target peripheral opioid receptors for postoperative pain relief while minimizing systemic opioid side effects, low doses of buprenorphine hydrochloride (0.8 up to 4.8 mg mL) were loaded into prefabricated, hydrophilic, degradable polyethylene glycol-based micropheres (PEG-MS, 50-100 μm) used as a drug delivery platform.

Glaucoma is a trans-synaptic neurodegenerative disease, and the pathological increase in intraocular pressure (IOP) is a major risk factor of glaucoma. High IOP alters microstructure and morphologies of the brain tissue. Since mechanical properties of the brain are sensitive to the alteration of the tissue microstructure, we investigate how varying durations of chronic elevated IOP alter brain mechanical properties.

Purpose: This study aimed to elucidate the regulatory role of Runt-related transcription factor 1 (RUNX1) in corneal neovascularization (CoNV) and its possible mechanisms.
Methods: In VEGF-induced human umbilical vein endothelial cells (HUVECs), lentiviral vectors were used to knock down or overexpress RUNX1, and plasmid transfection was employed to knock down P300. EdU assay, Transwell assay, and tube formation assay were conducted to assess cell proliferation, migration, and tube formation ability, respectively.
