Perry S Binder
The current nonsurgical approaches for the correction of presbyopia are spectacles or contact lenses or the use of pharmaceuticals to create an artificial pupil and/or to stimulate residual accommodation. Refractive surgical procedures use a monovision approach and/or a multifocal corneal laser ablation with or without the induction of negative spherical aberration to improve near vision. More recently, new surgical approaches include intracorneal inlays. Inlay approaches include increasing corneal curvature alone, implanting a multifocal inlay, or by implanting a small aperture device that functions as a pinhole to restore unaided near and intermediate visual acuity...

We present a giant ocular surface squamous neoplasia (OSSN) measuring approximately 20×18 mm arising from the fornix and wrapping the entire 12 clock hours of the cornea. The surgical excision was performed with preservation of the corneal surface. A 3-mm clear margin was obtained all around the mass. The histopathology confirmed as moderately differentiated squamous cell carcinoma with clear margins. The postoperative period was uneventful, and a clear cornea without a residual scar with best corrected visual acuity of 20/20 was attained...

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...
