To the best of our knowledge, there have been no reports of corneal hydrops associated with diabetic ketoacidosis. The present study first reports a case of a 20-year-old male patient with diabetic ketoacidosis-induced corneal hydrops. The patient exhibited mild hydrops in their left eyelid, which was accompanied by mixed hyperemia, and hazy turbid in a white color was observed in the cornea. To alleviate the corneal hydrops, 5% glucose was administered dropwise to the left eye for 2 h to alleviate the inflammation...

Diabetic retinopathy (DR) is one of the most prevalent microvascular complications of diabetes and one of the most frequent causes of blindness in active age. Etiopathogenesis behind this important complication is related to several biochemical, hemodynamic and endocrine mechanisms with a preponderant initial role assumed by polyol pathways, increment of growth factors, accumulation of advanced glycation end products (AGE), activation of protein kinase C (PKC), activation of the renin-angiotensin-aldosterone system (RAAS), and leukostasis...

Although sensory reinnervation occurs after injury in the peripheral nervous system, poor reinnervation in the elderly and those with diabetes often leads to pathology. Here we quantify sub-basal axon density in the central and peripheral mouse cornea over time after three different types of injury. The mouse cornea is highly innervated with a dense array of sub-basal nerves that form a spiral called the vortex at the corneal center or apex; these nerves are readily detected within flat mounted corneas. After anesthesia, corneal epithelial cells were removed using either a dulled blade or a rotating burr within an area demarcated centrally with a 1...

BACKGROUND AND PURPOSE: Abnormally induced angiogenesis and lymphangiogenesis are associated with human diseases, including neovascular eye disease. Substances that inhibit these processes may have potential as an attractive therapeutic strategy for these diseases. EXPERIMENTAL APPROACH: In vitro and in vivo angiogenesis and/or lymphangiogenesis were assessed in VEGF- or hypoxia-stimulated endothelial and retinal cells and in animal models of oxygen-induced retinopathy (OIR), streptozotocin-induced diabetic retinopathy (SIDR), suture-induced inflammatory corneal neovascularization (SICNV) and silver nitrate-induced corneal neovascularization...

Many lipids present in cellular membranes are phosphorylated as part of signaling cascades and participate in the recruitment, localization, and activation of downstream protein effectors. Phosphatidylinositol (3,4,5)-trisphosphate (PtdIns(3,4,5)P3) is one of the most important second messengers and is capable of interacting with a variety of proteins through specific PtdIns(3,4,5)P3 binding domains. Localization and activation of these effector proteins controls a myriad of cellular functions including cell survival, proliferation, cytoskeletal rearrangement, and gene expression...

Inflammation, neurodegeneration and microvascular irregularities are included in the spectrum of defects associated with diabetic retinopathy. Here, we evaluated intraocular deliverability features of two pigment epithelium-derived factor (PEDF) derivatives given as eye drops and their efficacy in modulating diabetes-induced retinal complications. The antiangiogenic PEDF60-77 (P60) and neuroprotective PEDF78-121 (P78) derivatives were applied to Ins2(Akita) mouse eyes once a week for 15 wks at the onset of hyperglycemia...

Scaffolds are implants or injects, which are used to deliver cells, drugs, and genes into the body. Different forms of polymeric scaffolds for cell/drug delivery are available: (1) a typical three-dimensional porous matrix, (2) a nanofibrous matrix, (3) a thermosensitive sol-gel transition hydrogel, and (4) a porous microsphere. A scaffold provides a suitable substrate for cell attachment, cell proliferation, differentiated function, and cell migration. Scaffold matrices can be used to achieve drug delivery with high loading and efficiency to specific sites...

INTRODUCTION: Beyond their decades of long use as broad-spectrum antibiotics, tetracyclines and their derivatives have been shown to exhibit non-antimicrobial properties including their ability to interact with matrix metalloproteinases (MMP), tissue inhibitors of MMPs, growth factors and cytokines. As such, they are capable of affecting inflammation, immunomodulation, cell proliferation, and angiogenesis. Although they have been used to treat a variety of conditions including acne, cutaneous sarcoid, and rheumatoid arthritis, amongst others, their use in treating ophthalmologic disease is in its infancy...

Thyroidorbithopaty is inflammatory disease against the autoimmune reaction. Clinical symptoms are connected within-creasing the volume of retrobulbar tissues. As a result of the autoimmune reaction is reaching to the blow-up, thickening extrabulbar muscles, of appearance of the swelling of the inflammable body of the fat body and tear glands. Heightened retrobulbar pressure is leading to the exophthalmos of the eyeball. He can be a consequence of the exophthalmos insuffiency of eyelids, drying, ulcerations of the cornea...

The cornea epithelium responds to injury by synthesizing several cytokines, growth factors, and tissue remodeling molecules. Proinflammatory cytokines have been implicated in the inflammation that follows corneal epithelial injury and cytokine-mediated processes play a significant role in corneal epithelial wound healing. Poorly regulated corneal inflammatory reactions that occur after injury can retard healing. In turn, persistent corneal epithelial defects and inflammation may lead to ocular morbidity and permanent visual loss...

Impaired wound healing is a common complication of diabetes. Although it is well known that both macrophages and blood vessels are critical to wound repair, the role of wound-associated lymphatic vessels has not been well investigated. We report that both the presence of activated macrophages and the formation of lymphatic vessels are rate-limiting to the healing of diabetic wounds. We have previously shown that macrophages contribute to the lymphatic vessels that form during the acute phase of corneal wound healing...

The wound healing process following tissue injury consists of a highly regulated sequence of events. Besides many biological activities on both neuronal and nonneuronal cells, nerve growth factor (NGF) has been proposed as an important component of wound healing and tissue repair process in vivo and in vitro. For example, NGF accelerates the rate of wound healing both in normal mice and healing-impaired diabetic mice, and has a potent pharmacological effect in the treatment for ulcer of the skin and cornea in humans...

Angiogenesis is a key mechanism that influences several physiological and pathological processes, including wound healing. During the past decades, many groups have shown that controlling angiogenesis might be an answer to overcome pathological situations when this process is out of control. Many altered metabolic states exert considerable influence on the development of angiogenesis. We have chosen diabetes as a model of a progressive metabolic disease with many associated conditions, including an alteration of wound healing dynamics described elsewhere...

PURPOSE: Leukocyte endothelial interactions are a key feature of ocular angiogenesis but also play a role in nonproliferative vascular alterations as are found in early diabetes or uveitis. The adhesion of leukocytes to endothelial cells during inflammation is a multistep process that involves leukocyte rolling, adhesion, and extravasation mediated by selectins, cell adhesion molecules (CAMs), integrins, and chemokines. Heparan sulfate (HS) is known to bind to and modify the function of these molecules under physiological conditions...
