A double-blind cross-over trial of timolol maleate (Timoptol) while routine medical therapy was continued gave the result that pressure was reduced by 3.22 mmHg is compared to placebo and 5.01 compared to pre-timolol levels in 24 patients. There was also a small (1.858 mmHg) drop in pressure in placebo treated eyes, a small and statistically significant drop in resting pulse rate, 76.67 to 71.3...

Xiurenbagrus dorsalis, a new cave-dwelling amblycipitid catfish species, is described based on one specimen collected from the Pearl River drainage in Guangxi, China. The new species can be distinguished from congeners in having a unique combination of features, including the absence of eyes, long barbels, dorsal-fin origin posterior to vertical line at tip of pectoral fins and an adipose fin c...

A blind randomised cross-over study was conducted on 10 patients (20 eyes) to compare the effect in patients with open-angle glaucoma of metipranolol 0.3% with that of timolol 0.25% on intraocular pressure following one month's topical instillation with each preparation alone. There was no statistically significant difference in intraocular pressure reduction between these two preparations, and...

Two new lysianassoid amphipod species, Ambasia anophthalma n. sp. and Bathyamaryllis biscayensis n. sp., are described based on adult females collected in the North Eastern Atlantic Ocean (Bay of Biscay) by an autonomous bait system deployed on the sea bottom at a depth of 1460-1550 m. These two species are characterized by the absence of eyes (blind species). They belong to genera which includ...

statement of problem: blindness as a disability seems to produce difficulties to reach an ideal heath status of the teeth. moreover ordinary educational health programmes for this group of population, especially children, are not successful. purpose: investigate the dental health status of these children and to see if they are really different with the normal population. materials and methods: ...

PURPOSE To investigate whether dilute brimonidine (0.025%) reduces patient discomfort, subconjunctival hemorrhage, and injection after LASIK without a significant increase in the rate of flap complications or surgical enhancements. METHODS This randomized, double-blind, prospective study enrolled 180 patients (360 eyes) in a contralateral eye comparison of topical dilute brimonidine, naphazol...

Most known starfish species possess a compound eye at the tip of each arm, which, except for the lack of true optics, resembles an arthropod compound eye. Although these compound eyes have been known for about two centuries, no visually guided behaviour has ever been directly associated with their presence. There are indications that they are involved in negative phototaxis but this may also be...

Chapter 2 provided ways to move a mobile robot. The coming chapter introduces the robot’s “eyes and ears”. Without sensors, the robot is completely blind to the world. Motion commands can be sent out, but no information would return to the robots brain. As mentioned in Chapter 1, the robot makes decisions based on its internal information state (I-state). The I-states will be constructed from t...

INTRODUCTION Currently ocular combat injuries are complex and associated with poor visual outcomes. Our objective is to characterize the military population that suffer land mine combat ocular trauma in Colombia and identify the type of wound, treatment and visual outcomes. METHODS Retrospectively review of medical history of soldiers evaluated in Pablo Tobon Uribe Hospital, whom had land min...

The eyelids are the thinnest skin in the body, leading to be easy for the blood vessels to show through the skin caused a swollen and dark appearance called puffy eyes. Placing refrigerated damp tea bags on the eyelids has been believed for a long time that it can reduce the puffy eyes due to the vasoconstriction of caffeine. This study aimed to characterize physicochemical properties and to de...
