Ocular toxicities are among the most common adverse events resulting from targeted anticancer agents and are becoming increasingly relevant in the management of patients on these agents. The purpose of this study is to provide a framework for management of these challenging toxicities based on objective data from FDA labels and from analysis of the literature. All oncologic drugs approved by the FDA up to March 14, 2015, were screened for inclusion. A total of 16 drugs (12 small-molecule drugs and 4 monoclonal antibodies) were analyzed for ocular toxicity profiles based on evidence of ocular toxicity...

Kingella kingae had rarely been reported as a causative organism for corneal ulcer and had not been described before in vernal keratoconjunctivitis (VKC). Generally regarded as commensals of respiratory tract particularly in young children, it had however been isolated from the corneal ulcer scraping of both adult and children. We report a case of bacterial ulcer with isolation of Kingella kingae from the corneal scraping in a young child with underlying VKC.

Prashant Garg, Sujata Das, Aravind Roy
Collagen cross-linking is gaining popularity not only for arresting the progression of keratoconus but also other indications including management of corneal infections. In this review article, we analyzed the published literature to understand the level of evidence for its use in corneal ulcer. Photoactivated riboflavin and ultraviolet A light are known to possess antimicrobial properties. The treatment also induces formation of inter- and intra-fibrillar bonds, thereby making the corneal collagen resistant to the action of proteases arresting stromal melt...

BACKGROUND: Microsporidial stromal keratitis poses several diagnostic challenges. Patients may present with corneal ulceration, marked stromal thinning, or even as a quite corneal scar. The presentation of microsporidial stromal keratitis commonly mimics viral keratitis. Microbiology scrapings are usually helpful; however, scraping and culture-negative cases pose a significant diagnostic dilemma. Histopathological examination is diagnostic but shows varying degree of inflammation, predominantly composed of polymorphonuclear leukocytes...

The purpose of this study was to investigate whether myofibroblast-related fibrosis (scarring) after microbial keratitis was modulated by the epithelial basement membrane (EBM) injury and regeneration. Rabbits were infected with Pseudomonas aeruginosa after epithelial scrape injury and the resultant severe keratitis was treated with topical tobramycin. Corneas were analyzed from one to four months after keratitis with slit lamp photos, immunohistochemistry for alpha-smooth muscle actin (α-SMA) and monocyte lineage marker CD11b, and transmission electron microscopy...

Colletotrichum species have been reported infrequently as the cause of keratitis or subcutaneous lesions. The patient we describe developed keratitis after ocular trauma. The sample from the corneal scrapings grew Colletotrichum gloeosporioides as identified from morphological characters and DNA sequence of the 'Internal Transcribed Spacer' (ITS) region. The patient underwent topical application of amphotericin-B followed by itraconazole and natamycin treatment. Simultaneous oral voriconazole regimen leads to complete regression of corneal ulcer...

Immune mediated keratitis (IMMK) is primarily a non-ulcerative keratitis in horses causing intermittent ocular pain, eventually resulting in visual impairment. Affected horses typically respond to immunomodulatory treatment. However, the underlying cause of the disease remains enigmatic. The current study was undertaken to investigate the presence of autoantibodies in horses with immune mediated keratitis. Using 28 horses with IMMK and 27 healthy controls screening for serum autoantibodies against the corneal proteome using indirect immunofluorescence, one-dimensional (1DE) and two-dimensional electrophoresis (2DE) with subsequent western blot analysis was performed followed by mass spectrometric identification of bands or spots of interest...

BACKGROUND: Infectious keratoconjunctivitis (IKC) is a transmissible disease in semi-domesticated Eurasian reindeer (Rangifer tarandus tarandus). It is regarded as multifactorial and a single causative pathogen has not yet been identified. From clinical outbreaks we have previously identified Cervid herpesvirus 2 (CvHV2) and Moraxella bovoculi as candidates for experimental investigations. Eighteen reindeer were inoculated in the right eye with CvHV2 (n = 5), M. bovoculi (n = 5), CvHV2 and M...

PURPOSE OF REVIEW: A state of limbal stem cell deficiency (LSCD) can be secondary to a number of etiologies, resulting in either a reduction in the total number of limbal stem cells or an abnormality in stem cell function. Initially, the epithelium becomes irregular and hazy; however, this condition may progress to persistent corneal epithelial defects, stromal scarring, ulceration, and even perforation. Since LSCD secondary to a variety of etiologies may be reversible, and various factors are prognostic of disease progression, timely diagnosis is important...
