Ocular adverse effects of interferon are described during the treatment of malignant diseases and chronic viral hepatitis with interferon alpha. At this time, there is no report of these effects during multiple sclerosis treatment with interferon beta-1b. The authors report a bilateral retinopathy during this treatment. The production of neutralizing… (More)
Humans are known to regulate the timing of interceptive actions by modeling, in a simplified way, Newtonian mechanics. Specifically, when intercepting an approaching ball, humans trigger their movements a bit earlier when the target arrives from above than from below. This bias occurs regardless of the ball's true kinetics, and thus appears to reflect an a… (More)
We are interested in this paper in the family of curves M (p, k, r, n), solutions of equation z n = αz k + (1 − α), where z is a complex variable, n, k, p and r are nonzero integers and α is a real number greater than 1. Expressing each of these curves in polar coordinates (ρ, θ), we will prove that ρ (θ) is an increasing function.
Central retinal vein occlusion (CRVO) is usually seen in older adults and is often associated with systemic vascular disease, this is much less evident in young people. A case report of a 28-year-old woman presented a central retinal vein occlusion in her left eye. This young woman was treated with antiandrogenic drug. Investigations revealed an abnormality… (More)
We report a case of Birdshot retinochoroidopathy associated with ocular toxicity due to tamoxifen. Adverse drug effects were suspected due to the presence of yellow-white dots in the paramacular region and the fovea and by modifications of the retinal epithelial pigments. Ocular toxicity should be suspected as it may be reversible if recognized and stopped… (More)
