Amblyopia is an example of abnormal visual development that is clinically defined as a reduction of best corrected Snellen acuity to less than 6/9 (20/30) in one eye or a two-line difference between the two eyes, with no visible signs of eye disease. We describe a sequential management program for anisometropic amblyopia that consists of four steps: (1) the(More)
A second extracellular protease from myxobacter strain AL-1 has been purified to homogeneity and named protease II; the enzyme crystallizes as fine needles. The extracellular, cell wall lytic protease reported previously from the same organism is now designated protease I. Protease II exhibits a pH optimum of 8.5 to 9.0 and is stable from pH 3.0 to 9.0. The(More)
PURPOSE To describe the efficacy, outcomes, and complications of confluent laser technique in a cohort of premature infants with threshold retinopathy of prematurity. Laser photocoagulation has a good treatment outcome in the management of retinopathy of prematurity; however, the number and density of laser spots remains debatable. Laser treatment can be(More)
OBJECTIVE The multifunctional cytokine interleukin-6 (IL-6) has actions on multiple cell types, including promotion of the development of immune cells and osteoclasts. Periapical inflammation as the result of root canal infection is characterized by the accumulation of inflammatory cells and bone resorption. The effect of IL-6 on periapical lesion formation(More)
The profound visual deficits associated with early monocular form deprivation (MD) are caused largely by competitive binocular interactions in the visual cortex. We tested the hypothesis that disrupting normal cortical binocularity prior to the onset of MD would reduce the degree of form deprivation amblyopia compared to that produced in animals that had(More)
In order to investigate the effects of transportation stress on metabolic activities, we measured the changes in plasma lipoprotein and catecholamine levels in those rats that had just arrived in our Animal Facility and age-matched rats which had acclimatized in the Facility for at least 21 days. The acclimatized rats were considered as control, and the(More)
