Pegaptanib Reduces Foveal Thickness in Macular Edema
FRIDAY, April 13 (HealthDay News) -- Intravitreally administered injections of the selective vascular endothelial growth factor (VEGF)-165 inhibitor pegaptanib significantly reduces foveal thickness and improves visual acuity in patients with diabetes and macular edema, according to a study published online April 5 in the British Journal of Clinical Pharmacology.
Bevacizumab Offers Lasting Improvement in Macular Edema

Ocular Tremors Pervasive in Patients With Parkinson's
TUESDAY, April 10 (HealthDay News) -- Ocular tremors, which prevent eye stability while fixating on a target, are pervasive among patients with Parkinson's disease, according to a study published online April 9 in the Archives of Neurology.
Immunotherapy Tied to Lower Alzheimer's CSF Biomarkers
FRIDAY, April 6 (HealthDay News) -- For patients with mild-to-moderate Alzheimer's disease, immunotherapy treatment with the anti-β-amyloid (Aβ) monoclonal antibody bapineuzumab results in lower concentrations of two cerebrospinal fluid (CSF) biomarkers: total (T)-tau and phosphorylated (P)-tau, according to a study published online April 2 in the Archives of Neurology.
Medical Malpractice Claims Incur Substantial Defense Costs
WEDNESDAY, April 4 (HealthDay News) -- Defense costs for medical malpractice claims vary among specialties and are higher for claims that result in indemnity payments, according to a letter published in the April 5 issue of the New England Journal of Medicine.
Fluoroquinolone Use Linked to Retinal Detachment
TUESDAY, April 3 (HealthDay News) -- The use of the oral fluoroquinolone antibiotics is associated with an increased risk of retinal detachment, although the absolute risk is small, according to a study published in the April 4 issue of the Journal of the American Medical Association.
Serious Eye Disease Linked to Bisphosphonate Use
