Primary malignant melanoma of the vagina is an extremely uncommon malignancy comprising of less than 10% malignancies of the female genital tract and 0.3% of all melanomas. Melanoblasts are neural crest derivatives and are notorious for causing primary cutaneous neoplasms. However, they involve virtually every organ of the body including eye, intestines and ocular mucosa, probably due to aberrancies in cell migration. Vagina is a rare site and primary melanoma of the vagina occurs in postmenopausal women with vaginal discharge, bleeding, or mass as common presenting complaints...

Infectious endophthalmitis is an important cause of vision loss worldwide. This entity most often occurs as a complication of intraocular surgery especially following cataract surgery or intravitreal injection. Endophthalmitis is regarded as a serious complication following ocular surgery and the final visual outcome is fundamentally contingent on timely recognition and intervention. Intravitreal and oral antibiotics in combination with pars plana vitrectomy or vitreous aspiration remain the mainstay in the management of endophthalmitis...

Intraocular tuberculosis presents a diagnostic challenge because of its protean clinical manifestations. Thus, it becomes imperative to distinguish chorioretinal inflammation due to tuberculosis from other infectious as well as non-infectious posterior uveitis since the clinical manifestations of these entities may be quite similar. With advancing technology, a number of novel imaging modalities are available today that enable in vivo near-histologic assessment of the chorioretinal tissue, greatly aiding the clinician in establishing a diagnosis and monitoring the therapeutic response of tubercular lesions...

The vesicating agents sulfur mustard (SM) and lewisite (LEW) are potent chemical warfare agents that primarily cause damage to the ocular, skin, and respiratory systems. However, ocular tissue is the most sensitive organ, and vesicant exposure results in a biphasic injury response, including photophobia, corneal lesions, corneal edema, ulceration, and neovascularization, and may cause loss of vision. There are several reports on ocular injury from exposure to SM, which has been frequently used in warfare. However, there are very few reports on ocular injury by LEW, which indicate that injury symptoms appear instantly after exposure and faster than SM...

PURPOSE OF REVIEW: Microbial keratitis is one of the leading causes of ocular morbidity. The standard treatment consists of antibiotics, which is intensive and is fraught with risks of antibiotic resistance. Corneal collagen cross-linking (CXL) has recently been advocated as an adjunctive therapy for management of microbial keratitis. The addition of CXL to ongoing antimicrobial treatment can have a potential effect on overall duration of the disease, need for corneal transplantation, final visual outcome, and long-term impact on drug resistance pattern...

Cyclosporine A (CsA) has long been the mainstay treatment for dry eye syndrome (DES), one of the most common disorders of the eye. However, the poor water solubility of CsA renders it difficult to formulate it into topical ocular dosage forms. Restasis® is currently the only US Food and Drug Administration (FDA)-approved CsA formulation, while Ikervis® has recently been launched in Europe, with both commonly associated with severe ocular discomfort. Therefore, several CsA formulations have been investigated with the aim to improve bioavailability while reducing adverse effects associated with the marketed formulations...

Ocular injury by lewisite (LEW), a potential chemical warfare and terrorist agent, results in edema of eyelids, inflammation, massive corneal necrosis and blindness. To enable screening of effective therapeutics to treat ocular injury from LEW, useful clinically-relevant endpoints are essential. Hence, we designed an efficient exposure system capable of exposing up to six New-Zealand white rabbits at one time, and assessed LEW vapor-induced progression of clinical ocular lesions mainly in the cornea. The right eye of each rabbit was exposed to LEW (0...

BACKGROUND: Central vision loss caused by age-related macular degeneration (AMD) is the leading cause of blindness among the elderly in developed countries. Neovascular AMD is characterized by choroidal neovascularization (CNV). Growth of new blood vessels in patients with neovascular AMD is driven by a complex process that involves a signal protein called vascular endothelial growth factor A (VEGF-A). Anti-VEGF drugs that block this protein include ranibizumab, bevacizumab, and aflibercept...

Topical drug administration is the preferred route of drug delivery to the eye despite the poor bioavailability. To develop more efficient drug carriers, reliable in vitro or ex vivo models are required in the early stages of formulation development, with such methods being faster, cheaper, and more ethical alternatives to in vivo studies. In vitro cell culture models are increasingly being used for transcorneal penetration studies, with primary cell cultures and immortalized cell lines now giving way to the development of organotypic corneal constructs for studying ocular drug bioavailability...
