N R Marchenko
Treatment of allergic diseases of eyelids and conjunctiva (conjunctivites and blepharoconjunctivites) often presents difficulties due to peculiarities of their pathogenesis - allergic and vascular reactions, disorder of lacrimal production, meibomian gland dysfunction, and possible bacterial contamination. It has been suggested to use Ocumethyl, which contains zinc sulfate (binding, drying, anti-inflammatory, and antiseptic effect), diphenhydamine hydrochloride (an Н1-antihistamine that decreases capillary permeability and helps resolve conjunctival and eyelid edema), naphazoline hydrochloride (a sympathomimetic notable for its strong, rapid, and long-lasting vasoconstrictive effect), and methylene blue (antiseptic effect, disintoxication, and antioxidant activity)...

Several studies found that 50-100% serum eye drops provided greater benefits without inducing detrimental effects on the corneal epithelial healing. This study assessed the efficacy of undiluted serum eye drops for the treatment of persistent corneal epithelial defects (PED). A total of 109 eyes received 100% serum eye drops for PED were recruited into this study. The data were compared with an historical control group of 79 eyes with PED who received conventional treatments from 2006-2011 at the same institution...

Efforts to reduce myopia progression in childhood are driven by the increasing incidence of high myopia and its attendant health risks. Interventional approaches to reduce myopia progression in childhood have included the use of spectacles, contact lens, and pharmacological methods, of which the latter appear to be most promising. We review the use of topical atropine eye drops in the retardation of myopia progression in children and discuss the efficacy and safety profiles when used at different concentrations (1...

Acanthamoeba spp. are free-living amoeba found in a wide variety of natural habitats. The high percentage of the presence of Acanthamoeba in different environmental sources represents a sanitary risk for public health, especially immunocompromised patients and contact lens wearers. Acanthamoeba can cause granulomatous amoebic encephalitis, otitis, lung lesions, and skin infections in individuals with immune deficiencies. In the present study, the status of contamination of water sources in Isfahan, central Iran is analyzed through parasitological method...

We present and test a methodology for generating simultaneous vision with a deformable mirror that changed shape at 50 Hz between two vergences: 0 D (far vision) and -2.5 D (near vision). Different bifocal designs, including toric and combinations of spherical aberration, were simulated and assessed objectively. We found that typical corneal aberrations of a 60-year-old subject changes the shape of objective through-focus curves of a perfect bifocal lens. This methodology can be used to investigate subjective visual performance for different multifocal contact or intraocular lens designs...

The vertebrate ciliary ganglion (CG) is a relay station in the parasympathetic pathway activating the iris sphincter and ciliary muscle to mediate pupillary constriction and lens accommodation, respectively. While the postganglionic motoneurons in the CG are cholinergic, as are their inputs, there is evidence from avian studies that GABA may also be involved. Here, we used light and electron microscopic methods to examine the GABAergic innervation of the CG in Macaca fascicularis monkeys. Immunohistochemistry for the gamma aminobutyric acid synthesizing enzyme glutamic acid decarboxylase (GAD) and choline acetyltransferase (ChAT) revealed that all CG neurons are contacted by ChAT-positive terminals...
