Purpose: To report a case of severe interface inflammation, flap edema, and endothelial cell loss after laser-assisted in situ keratomileusis (LASIK).
Methods: A 22-year-old woman with no previous ocular abnormality underwent LASIK for myopia. The surgery was uneventful. Her preoperative endothelial count was 3,066 and 2,898 cells per square millimeter OD and OS, respectively.
Results: On the first postoperative day, the right eye had interface infiltrates, flap edema, and radiating Descemet's folds and the left eye had flap edema with interface infiltrates. Bilateral flap relifts and thorough irrigation were performed on the second day, followed by amputation of the nonviable flap in the right eye on the third day. On medical management, the corneal edema resolved for more than 1 month. At 6 months, the best-corrected vision was 20/32 OD and 20/25 OS, with endothelial cell count of 1,763 and 2,055 cells per square millimeter OD and OS, respectively.
Conclusions: Endothelial status should be monitored in patients with a severe interface reaction or severe diffuse lamellar keratitis after LASIK.

Diabetic wounds are complicated by underlying peripheral vasculopathy. Reliance on vascular endothelial growth factor (VEGF) therapy to improve perfusion makes logical sense, yet clinical study outcomes on rescuing diabetic wound vascularization have yielded disappointing results. Our previous work has identified that low endothelial phospholipase Cγ2 (PLCγ2) expression hinders the therapeutic effect of VEGF on the diabetic ischemic limb.

Neovascular age-related macular degeneration and diabetic macular edema are leading causes of vision-loss evoked by retinal neovascularization and vascular leakage. The glycoprotein microfibrillar-associated protein 4 (MFAP4) is an integrin αβ ligand present in the extracellular matrix. Single-cell transcriptomics reveal MFAP4 expression in cell-types in close proximity to vascular endothelial cells including choroidal vascular mural cells and retinal astrocytes and Müller cells.

Gene therapy with Adeno-Associated Virus (AAV) vectors requires knowledge of their tropism within the body. Here we analyze the tropism of ten naturally occurring AAV serotypes (AAV3B, AAV4, AAV5, AAV6, AAV7, AAV8, AAV9, AAVrh8, AAVrh10 and AAVrh74) following systemic delivery into male and female mice. A transgene expressing ZsGreen and Cre recombinase was used to identify transduction in a cell-dependent manner based on fluorescence.

The aberrant vascular response associated with tendon injury results in circulating immune cell infiltration and a chronic inflammatory feedback loop leading to poor healing outcomes. Studying this dysregulated tendon repair response in human pathophysiology has been historically challenging due to the reliance on animal models. To address this, our group developed the human tendon-on-a-chip (hToC) to model cellular interactions in the injured tendon microenvironment; however, this model lacked the key element of physiological flow in the vascular compartment.

Background: Cardiovascular risk factors (CRFs) like hypertension, high cholesterol, and diabetes mellitus are increasingly linked to cognitive decline and dementia, especially in cerebral small vessel disease (cSVD). White matter hyperintensities (WMH) are closely associated with cognitive impairment, but the mechanisms behind their development remain unclear. Blood-brain barrier (BBB) dysfunction may be a key factor, particularly in cSVD.
