Background Graves' disease is an autoimmune disorder leading to hyperthyroidism. It is often associated with ophthalmic manifestations. Graves' disease is reported to be rare in the paediatric population. Patients and Methods We performed a retrospective analysis on all patients diagnosed with ophthalmopathy related to Graves' disease at a paediatric age (less than 18 years old) in our institution between 2004 and 2015. Results Eight patients were identified: 6 females and 2 males. The median age at diagnosis was 11...

Members of the genus Acanthamoeba are of the most common protozoa that has been isolated from a variety of environment and affect immunocompromised individuals, causing granulomatous amoebic encephalitis and skin lesions. Acanthamoeba, in immunocompetent patients, may cause a keratitis related to corneal microtrauma. These free-living amoebas easily adapt to the host environment and wield metabolic pathways such as the energetic and respiratory ones in order to maintain viability for long periods. The energetic metabolism of cysts and trophozoites remains mostly unknown...

PURPOSE: Currently, the most feared complication by ophthalmologists of contact lens (CL) wear is microbial keratitis (MK), even though its incidence remains low. It is also a significant financial burden for society. This study aimed to identify the risk factors for CL-related MK especially with regard to hygiene and pattern of use, in a large, prospective, multicenter, case-control study. METHODS: A multicenter retrospective case-control study was designed. The CL-related MK subpopulation (case) was compared with healthy CL wearers (control) using a 52-item anonymous questionnaire designed to determine subject demographics, lens wear history, lens type and disinfection solution, fitting, patient education, hygiene and maintenance of contact lenses, and patient history...

REVIEW
Lara K Maxwell
Since vaccination may not prevent disease, antiherpetic drugs have been investigated for the therapy of several equine herpesviruses. Drug efficacy has been assessed in horses with disease, but most evidence is in vitro, in other species, or empirical. Oral valacyclovir is most often administered in the therapy of equine herpesvirus type-1 (EHV-1) to protect adult horses from equine herpesvirus myeloencephalopathy, while oral acyclovir is frequently administered for EHV-5 infection in the therapy of equine multinodular pulmonary fibrosis...

Free living amoebae of the genus Acanthamoeba are the causal agents of a sight threatening ulceration of the cornea called Acanthamoeba keratitis, and the rare but usually fatal granulomatous amoebic encephalitis. Although there are many therapeutic options for the treatment of Acanthamoeba infections, they are generally lengthy and/or have limited efficacy. For the best clinical outcome, the treatments should target both the trophozoite and the cyst stages as the later are known to confer resistance to treatment...

BACKGROUND: Acyclovir (ACV)-resistant (ACVr) herpes simplex virus type 1 (HSV-1) infections are concern in immunocompromised patients. Most clinical ACVr HSV-1 isolates have mutations in the viral thymidine kinase (vTK) genes. The vTK-associated ACVr HSV-1 shows reduced virulence, but the association between the level of resistance and the virulence of the vTK-associated ACVr HSV-1 is still unclear. METHODS: The virulence in mice of 5 vTK-associated ACVr HSV-1 clones with a variety of ACV sensitivities, when inoculated through intracerebral and corneal routes, was evaluated in comparison with ACV-sensitive (ACVs) parent HSV-1 TAS...

Patients with atopic dermatitis frequently complain of ocular symptoms. The general dermatitis can directly affect the periocular skin and patients often present with chronic atopic blepharokeratoconjunctivitis. Early diagnosis of the characteristic ophthalmological alterations, such as blepharitis, allergic conjunctivitis, keratoconjunctivitis sicca, conjunctival scarring with formation of symblepharon and lid malpositioning, filiform keratitis, corneal plaques, (persistent) epithelial defects, corneal ulcers and keratoconus as well as appropriate stage-adapted treatment, including lid hygiene with preservative-free lubricants, topical and sometimes systemic anti-inflammatory therapy and surgical treatment are important for patients to prevent long-term damage of the ocular surface leading to severe visual impairment...

Herpetic stromal keratitis (HSK) is a disease that is typically associated with reactivation of a latent HSV-1 infection. This disease is driven, in part, by chemokines that recruit leukocytes to the cornea. Surprisingly, neutralization of CXCL10 significantly reduced disease, while B6-CXCL10-/- mice exhibited worse disease compared with similarly infected wild-type controls. We hypothesized that compensatory up-regulation of CXCL9 occurs in the absence of CXCL10. Analysis of CXCL9 expression in HSV-1-infected B6 mice and B6-CXCL10-/- mice revealed significantly more CXCL9 in B6-XCL10-/- mice...
