purpose: to compare the safety, efficacy, and visual results of laser in situ keratomileusis (lasik) in eyes with and without previous scleral buckling surgery in the same individuals. methods: in a prospective clinical trial, 14 eyes of 7 patients with myopic refractive error and history of scleral buckling in one eye, underwent lasik surgery in both eyes according to a standard surgical proto...

Insect adhesion is mediated by thin fluid films secreted into the contact zone. As the amount of fluid affects adhesive forces, a control of secretion appears probable. Here, we quantify for the first time the rate of fluid secretion in adhesive pads of cockroaches and stick insects. The volume of footprints deposited during consecutive press-downs decreased exponentially and approached a non-z...

PURPOSE To compare the structural outcome at 9 months of eyes treated with intravitreal injection of bevacizumab with fellow eyes treated with conventional laser photoablation in zone I type 1 retinopathy of prematurity (ROP). DESIGN Single randomized controlled trial. PARTICIPANTS All inborn babies with type 1 zone I ROP at a single institution were included in the study. One eye was rando...

Purpose. To investigate prognostic factors that influence the final visual acuity (VA) and to correlate the ocular trauma score (OTS) with the final VA in open globe injuries. Methods. A retrospective review of 298 patients with open globe injuries admitted to Tianjin Medical University General Hospital was carried out from January 1, 2010, till December 31, 2014. Prognostic factors influencing...

The failure of brittle and quasi-brittle polymers can be attributed to a multitude of random microscopic damage modes, such as fibril breakage, crazing, and microfracture. As the load increases, new damage modes appear, and existing ones can transition into others. In the example polymer used in this study--a commercially available acrylic bone cement--these modes, as revealed by scanning elect...

Assessing the geochemical signature and role of fluids in a key Variscan detachment zone demonstrates link between crustal deformation, thermo-mechanical events mineralization. We document meteoric fluid infiltration into ductile segment Late-Carboniferous Quiberon (QDZ), when synkinematic muscovite tourmaline crystallized equilibrated with deuterium-depleted surface-derived during high-tempera...

To the Editors: A male infant born at 36 weeks of gestation with a birth weight of 2,500 grams presented to our department at 37 weeks’ post-conceptional age. The infant was not admitted in any neonatal intensive care unit, had not received oxygen, and did not have a history of neonatal sepsis. He was otherwise healthy. The infant was brought for a retinal check-up because his elder sibling was...

PURPOSE To compare the clinical outcomes of intravitreal bevacizumab (IVB) injection, with different dosing (0.25 mg/0.01 ml versus 0.625 mg/0.025 ml) in each eye of the same patient with retinopathy of prematurity (ROP). METHODS Intravitreal bevacizumab (IVB) was injected into eight patients with stage 3+ in zone I or posterior zone II ROP (16 eyes). Bevacizumab, with different dosing (0.25 ...
