Evaluation of ultrasound velocity in enucleated equine aqueous humor, lens and vitreous body

BACKGROUND Sonographic ophthalmic examinations have become increasingly important in veterinary medicine. If the velocity of ultrasound in ocular tissues is known, the A-mode ultrasound method may be used to determine the axial intraocular distances, such as anterior chamber depth, lens thickness, axial length of the vitreous and axial globe length, which are required for intraocular lens (IOL)...

Lens epithelial cells in postoperative aqueous humor.

The aqueous humor during or after cataract surgery often contains red blood cells (RBCs) from blood; inflammatory cells from white blood cells (WBCs); fibrin, pigment cells, and fibroblasts from either the iris or the ciliary body; lens epithelial cells (LECs); and corneal endothelial cells. Since LECs may be related to postoperative complications, including a fibrin reaction and a secondary ca...

Antioxidant status of dog aqueous humor after extracapsular lens extraction.

We determined the antioxidant status of the aqueous humor after extracapsular lens extraction in 14 mongrel dogs weighing about 10 kg. The animals were examined by slit lamp biomicroscopy, applanation tonometry and indirect ophthalmoscopy. One eye was submitted to conventional extracapsular lens extraction and the other was used as control. Samples of aqueous humor were obtained by anterior cha...

Vitreous Humor Changes Expression of Iron-Handling Proteins in Lens Epithelial Cells

Purpose In humans, vitrectomy is associated with development of nuclear cataracts. Iron catalyzes free radical formation causing oxidative damage, which is implicated in cataract formation. This study was designed to determine if vitreous humor, which can initiate differentiation of lens epithelial cells, would have an effect on iron-handling proteins. Methods Cultured canine lens epithelial ...

Penetration of 0.3% ciprofloxacin, 0.3% ofloxacin, and 0.5% moxifloxacin into the cornea and aqueous humor of enucleated human eyes

We aimed to quantify the penetration of ciprofloxacin, ofloxacin, and moxifloxacin into the cornea and aqueous humor of cadaver eyes. A total of 60 enucleated eyes, not eligible for corneal transplantation, were divided into three groups and immersed in commercial solutions of 0.3% ciprofloxacin, 0.3% ofloxacin, or 0.5% moxifloxacin for 10 min. Whole corneas and samples of aqueous humor were th...
