Purpose: To describe a case of peripheral keratitis associated with erythema elevatum diutinum (EED), an unusual immune-complex-mediated cutaneous vasculitis.
Design: Observational case report.
Methods: A 25-year-old man who was diagnosed 15 months previously with erythema elevatum diutinum presented with an inflammatory peripheral keratitis of the left eye.

Purpose: To evaluate the safety, efficacy, and complications of radial keratotomy (RK) after photorefractive keratectomy (PRK) for myopia.
Setting: Laser Ultravision Institute. Montreal, Canada.

Purpose: To evaluate retrospectively the safety, efficacy, and complications of arcuate keratotomy (AK) in correcting naturally occurring astigmatism.
Setting: Laser Ultravision Institute, Montreal, Canada.
Methods: Surgically induced refractive change was evaluated in 25 eyes of 15 patients with naturally occurring astigmatism.
We used the ligand 3-N-(2'-F18)fluoroethylspiperone (FESP) and positron emission tomography (PET) to quantify in vivo serotonin S2 neuroreceptor density and affinity in the baboon frontal cortex. In the cortex, FESP binds specifically and exclusively to S2 receptors, and an equilibrium is reached when the rate of ligand-receptor association and dissociation become equal. Using multiple studies in the same baboon, an equilibrium (saturation) analysis approach provided a linear Hill plot with a slope of 1.
