Varicella zoster virus (VZV)-induced anterior uveitis (AU) may complicate the course of primary varicella infection typically seen in children. In adults, especially with advanced age, VZV AU is more commonly associated with herpes zoster ophthalmicus (HZO) with or without skin rash affecting the distribution of the ophthalmic nerve due to reactivation of the latent VZV in the trigeminal ganglion. While it is typically a mild self-limiting AU in primary infection, HZO AU is often accompanied by keratitis, may have a chronic recurrent course, and lead to sectoral iris atrophy, pupillary distortion, and ocular hypertension...

INTRODUCTION: Keratitis due to Nocardia infection is not commonly encountered in clinical practice and may therefore be mistaken for fungal or viral keratitis leading to delayed treatment and increased risk of permanent visual impairment. CASE: An otherwise healthy 27 years old Caucasian Active Duty military member presented to the clinic with three days of light sensitivity and irritation of his right eye. He carried a history of PRK in both eyes six years prior and admitted to recent contact lens overuse...

Background: Mutations leading to changes in properties, regulation, or expression of connexin-made channels have been implicated in 28 distinct human hereditary diseases. Eight of these result from variants of connexin 26 (Cx26), a protein critically involved in cell-cell signaling in the inner ear and skin. Lack of non-toxic drugs with defined mechanisms of action poses a serious obstacle to therapeutic interventions for diseases caused by mutant connexins. In particular, molecules that specifically modulate connexin hemichannel function without affecting gap junction channels are considered of primary importance for the study of connexin hemichannel role in physiological as well as pathological conditions...

Fungal keratitis, or keratomycoses, are corneal infections which must be considered in cases of corneal trauma, prior corneal surgery, chronic ocular surface disease, topical corticosteroids or contact lens wear. Filamentous fungi or yeasts may be involved. Presenting clinical features such as corneal infiltrates with feathery edges and/or raised surface, intact epithelium with deep stromal involvement, satellite lesions, endothelial plaques, lack of improvement with antibiotics and worsening with steroids are suggestive of fungal keratitis...

Acanthamoeba culbertsoni trophozoites, previously isolated from a human keratitis case with severe intraocular damage, were maintained in axenic culture. Co-incubation of amoebae with MDCK cell monolayers demonstrated an apparent preference of the amoebae to introduce themselves between the cells. The trophozoites appeared to cross the cell monolayer through the tight junctions, which resulted in decreased trans-epithelial resistance (TER) measurements. Unexpectedly, after co-incubation of amoebae with hamster corneas, we observed that the trophozoites were able to cross the different cell layers and reach the corneal stroma after only 12 h of interaction, in contrast to other Acanthamoeba species...
