#1
Robert Ritch
Exfoliation syndrome (XFS) is characterized by numerous ocular manifestations, the most important of these being glaucoma and cataract. Its ocular manifestations affect all of the structures of the anterior segment as well as conjunctiva and orbital structures. Exfoliation material is seen most prominently as characteristic white deposits on the anterior surface of the lens and the pupillary border of the iris. Both open-angle and angle-closure glaucoma are intimately associated with XFS. Other findings include zonular disruption, iris sphincter fibrosis, keratopathy, ocular surface disease, and retinal vein occlusion...

Interleukin 27 (IL-27) is a member of the IL-6/IL-12 family, and IL-27 receptor (IL-27R) consists of WSX-1 (the IL-27Rα subunit) and the signal-transducing subunit gp130. Human and mouse mast cells (MCs) express the IL-27R. To explore the expressions of IL-27/IL-27R subunits (WSX-1 and gp130) during acute ocular toxoplasmosis (OT), we established mouse model by intraocular injection of 500 Toxoplasma gondii RH strain tachyzoites. Histopathological changes were analyzed, MCs were counted by toluidine blue staining, and tryptase+ /IL-27+ MCs were examined by immunofluorescence double-staining in the eyes and cervical lymph nodes (CLNs) of T...

To improve the ocular bioavailability of the strongly hydrophilic moxifloxacin hydrochloride, hyaluronic-acid-modified lipid-polymer hybrid nanoparticles (HA-LCS-NPs) were designed and characterized. An in vivo precorneal retention study in rabbits showed that the mean residence time (MRT) and area under the curve (AUC0-6h ) of HA-LCS-NPs were up to 6.74-fold and 4.29-fold higher than those of the commercial product. An in vitro corneal penetration study in rabbits demonstrated that the apparent permeability coefficient (Papp) of HA-LCS-NPs was increased by 3...

Iodine has been recognized as an effective bactericide since the 1800's, and povidone-iodine (PI) solution has been applied to the ocular surface and periocular skin since the 1980's to prevent endophthalmitis in cataract surgery. In vitro, PI solution kills bacteria very quickly at dilute concentrations (0.05-1.0%). In many instances, PI kills bacteria more quickly at these dilute concentrations than more conventional (5%-10%) concentrations. This is due to greater availability of diatomic free iodine in dilute solution, the bactericidal component of PI...

INTRODUCTION: Surgical excision of large malignant lower eyelid tumors may cause important full-thickness eyelid defects. The reconstruction of such defects must restore the physiologic function of the eyelid and also re-establish an acceptable aesthetic result. MATERIALS AND METHODS: We report the outcomes of full-thickness excision of tumors extending over half of the horizontal lid length, followed by reconstruction using a nasal chondromucosal graft (coming from the ipsilateral ala of the nose) and an upper eyelid myocutaneous flap...

V Kocaba, O Damour, C Auxenfans, C Burillon
In France, endothelial dysfunction represents approximately one half of the indications for corneal transplants performed each year. However, the use of endothelial keratoplasty is limited by the technical difficulty of the procedure, a shortage of available grafts, and the potential for graft failure or rejection. These limitations are driving researchers to develop new, less invasive, and more effective therapies. Corneal endothelial cell therapy is being explored as a potential therapeutic measure, to avoid the uncertainty associated with grafting...

Adeno-associated virus (AAV) vector is a promising platform technology for ocular gene therapy. Recently clinical successes to treat choroidal neovascularization (CNV) in wet type age-related macular degeneration have been reported. However, because pathologic conditions of the retina may alter the tropism of viral vectors, it is necessary to evaluate the transduction efficiency of different serotypes of AAV vectors in the retinas with CNVs. Here, we show the patterns and efficacy of transduction of AAV2, -5, and -8 vectors in a laser-induced CNV mouse model...
