Holocene coastal evolution of Colorado River Delta based on diatom assemblages, Northern Patagonia, Argentina.

Diatom assemblages and coastal sedimentary facies succession in the deltaic plain of the Colorado River (Argentina) were studied in order to reconstruct the environment conditions in response to Holocene eustatic sea-level changes and delta progradation. Samples were selected from a 200-cm core (39°35'52" S, 62°6'43" W). Chronology was based on radiocarbon datings in bulk samples and mollusk shells.

Periocular port wine stain: the great ormond street hospital experience.

Purpose: To identify the sensitivity and specificity of risk factors for the development of glaucoma in patients with port wine stain (PWS).

Design: A retrospective case-control study involving a large cohort of patients with PWS.

Participants: A total of 216 patients (total of 252 eyes) with unilateral or bilateral PWS seen in the eye department in Great Ormond Street Hospital, London, United Kingdom.

Amniotic membrane transplantation in children with symblepharon and massive pannus.

Objective: To report our pediatric experience with amniotic membrane transplantation for ocular surface and forniceal reconstruction.

Methods: Retrospective case review of children who underwent superficial keratectomy, symblepharon lysis, and forniceal reconstruction using amniotic membrane transplantation. The underlying diagnosis, visual acuity, level of discomfort at first and last visits, and surgical details were noted.

Presence of mitomycin-C in the anterior chamber after photorefractive keratectomy.

Purpose: To assess the presence of mitomycin-C (MMC) in hen aqueous humor after photorefractive keratectomy (PRK).

Setting: Instituto Universitario de Oftalmobiología Aplicada, Faculty of Medicine, University of Valladolid, and Department of Analytical Chemistry, Faculty of Sciences, University of Valladolid, Valladolid, Spain.

Methods: Mitomycin-C 0.

Reproducibility of LASIK flap thickness using the Hansatome microkeratome.

Purpose: To evaluate the actual versus the expected thickness of laser in situ keratomileusis (LASIK) flaps and to determine the factors that affect flap thickness.

Setting: Centre For Sight, Queen Victoria Hospital, East Grinstead, United Kingdom.

Methods: A retrospective analysis of LASIK procedures in 757 consecutive eyes was done.
