OBJECTIVE: The laboratory diagnostic detection of herpes simplex virus (HSV) from eye samples must be practical, timely, and definitive for appropriate therapy. Although polymerase chain reaction (PCR) and/or cell culture can be definitive, HSV results can be delayed. Enzyme Linked Virus Inducible System (ELVIS) is a test that can provide results within 24 to 48 hr. We evaluated "AmpliVue HSV 1+2 Assay" as a molecular colorimetric test that can detect HSV (1 or 2) DNA within 1 hr. METHODS: Cornea/conjunctival samples were tested retrospectively with AmpliVue against 53 true-positive and 20 true-negative specimens collected in chlamydial transport medium...

Toxic keratoconjunctivitis (TK) is an underrecognized complication of ophthalmic drug use and various environmental or occupational exposures. A detailed history and clinical examination are important to identify the offending agent(s). Common drug-related causes of TK include preservatives in ophthalmic medications, topical antimicrobials, and topical anesthetics. Alternatives to benzalkonium chloride as well as preservative-free formulations should be considered in patients requiring long-term topical medication...

Meibomian glands secrete lipids (meibum) that form the surface lipid layer of the tear film and thereby prevent excessive evaporation of tear fluid. Meibomian gland dysfunction is a major cause of evaporative dry eye, which is more prevalent than aqueous-deficient dry eye. Noninvasive meibography with infrared light and an infrared charge-coupled device camera can detect morphological changes of meibomian glands in both upper and lower eyelids, whereas tear interferometry allows qualitative and quantitative evaluations of the lipid layer of the tear film...

Matthias Fuest, Jodhbir S Mehta
Corneal hydrops affects approximately 2.5% of keratoconus (KC) cases, predominantly young males approximately 25 years of age with steep cones. Often, patients are left with a vision-reducing corneal scar frequently necessitating surgical treatment. Penetrating keratoplasty (PK) has worse survival outcomes in hydrops than in general KC cases. Deep anterior lamellar keratoplasty (DALK) is a nonpenetrating technique believed to achieve equal or better outcomes in visual acuity, graft survival, endothelial rejection rates, and endothelial cell survival in comparison with PK, while maintaining globe integrity and the patients' Descemet membrane (DM) and endothelium...
