To determine the changes in the pulse amplitude (PA) and the pulsatile ocular blood flow (POBF) after scleral buckling (SB). Retrospectively, we studied 24 patients (average age, 52 years) who had undergone SB to repair a retinal detachment in one eye. The patients were divided into two groups: those in whom SB had been performed less than 6 months earlier(More)
In the ciliary muscle, the tonic contraction requires a sustained influx of Ca2+ through the cell membrane. However, little has hitherto been known about the route(s) of Ca2+ influx in this tissue that lacks voltage-gated Ca2+ channels. To identify ion channels as the Ca2+ entry pathway we studied the effects of carbachol (CCh) on freshly isolated bovine(More)
In this paper, we describe a novel technique for detecting raindrops using in-vehicle camera images. The appearance of raindrops on a car windshield can depend on their background, so it is often difficult to detect them using conventional template matching methods, which are based on image features. Initially, we extract potential raindrop regions from(More)
