(HealthDay)—Genotyping of two genetic risk alleles can be used to estimate the long-term risk of early and late age-related macular degeneration (AMD), but knowing the phenotype is important in assessing risk when early AMD is present, according to a study published online Nov. 9 in the Archives of Ophthalmology. http://medicalxpress.com/news/2012-11-genotyping-ids-long-term-macular-degeneration.html Ophthalmology Tue, 13 Nov 2012 18:10:04 EST news272048480 (HealthDay)—Long-term aggressive treatment of patients with macular edema with ranibizumab during a third year correlates with reduced mean foveal thickness (FTH) and improved best-corrected visual acuity (BCVA), according to research published online Oct. 8 in the Archives of Ophthalmology. http://medicalxpress.com/news/2012-10-long-term-ranibizumab-beneficial-macular-edema.html Ophthalmology Thu, 11 Oct 2012 18:30:01 EST news269194573 (HealthDay) -- A contact lens sensor (CLS) provides safe and tolerable 24-hour monitoring of intraocular pressure (IOP) patterns in patients with or suspected of having glaucoma, according to research published online Aug. 13 in the Archives of Ophthalmology. http://medicalxpress.com/news/2012-08-contact-lens-sensor-hour-intraocular.html Ophthalmology Wed, 15 Aug 2012 14:25:46 EST news264259491 A national consortium of researchers has published new findings that could change the standard of practice for those treating Fuchs' Endothelial Corneal Dystrophy (FECD), a disease characterized by cornea swelling that can eventually lead to the need for corneal transplantation. The Fuchs' Endothelial Corneal Dystrophy Genetics Multi-Center Study Group, led by co-principal investigators Jonathan Lass, MD, Charles I Thomas Professor and chair, Case Western Reserve University Department of Ophthalmology and Visual Sciences and director, University Hospitals Eye Institute, and Sudha Iyengar, PhD, professor, Departments of Epidemiology and Biostatistics, Genetics, and Ophthalmology, Case Western Reserve University School of Medicine, found that changes in the corneal thickness occur in patients at early stages of FECD even before swelling is observed in the clinical setting. Their study is published in the journal Archives of Ophthalmology. http://medicalxpress.com/news/2012-04-corneal-thickness-linked-early-stage.html Ophthalmology Mon, 09 Apr 2012 16:27:25 EST news253207616 People with strabismus (misalignment and limited movement of one or more eyes) are often teased about their crossed-eye appearance; those with more complex, disfiguring strabismus can become socially isolated and develop neck and back problems from having to turn their head to see properly. While surgery can correct eye position, it may require operation on several muscles, causing lengthy recovery, and sometimes overcompensates for the problem, requiring repeat operations. A single, simplified procedure adopted at Children's Hospital Boston has good results, researchers report, and allows for eye position to be fine-tuned in the recovery room or up to a week later, often avoiding re-operation. http://medicalxpress.com/news/2012-02-aligning-eyes-simpler-surgery-complex.html Other Mon, 13 Feb 2012 16:00:14 EST news248370739 Retinal microvascular changes appear to be associated with development of disability in performing activities of daily living among older adults, and retinal signs may be useful in predicting outcomes among this population, according to a report published Online First by Archives of Ophthalmology. http://medicalxpress.com/news/2011-11-retinal-microvascular-disability-daily-older.html Health Mon, 14 Nov 2011 16:26:56 EST news240510393 Repeated exposure of the eye to ophthalmic antibiotics appears to be associated with the emergence of resistant strains of microbes among patients undergoing intraocular injection therapy for neovascular retinal disease, according to a report in the September issue of Archives of Ophthalmology. http://medicalxpress.com/news/2011-09-ophthalmic-antibiotics-antimicrobial-resistance-intraocular.html Diseases, Conditions, Syndromes Mon, 12 Sep 2011 16:31:06 EST news235063799 In patients with glaucoma, frequent visual field testing may be associated with earlier detection of the condition's progression, according to a report published Online First by Archives of Ophthalmology, one of the JAMA/Archives journals. http://medicalxpress.com/news/2011-08-frequent-visual-field-earlier-glaucoma.html Diseases, Conditions, Syndromes Mon, 08 Aug 2011 16:10:22 EST news232030819 A new risk assessment model may help predict development of advanced age-related macular degeneration, according to a report published Online First by Archives of Ophthalmology, one of the JAMA/Archives journals. http://medicalxpress.com/news/2011-08-advanced-age-related-macular-degeneration.html Diseases, Conditions, Syndromes Mon, 08 Aug 2011 16:10:01 EST news232030924 Measuring oxygen during eye surgery, investigators at Washington University School of Medicine in St. Louis have discovered a reason that may explain why African-Americans have a higher risk of glaucoma than Caucasians. http://medicalxpress.com/news/2011-07-oxygen-eyes-african-americans-glaucoma.html Diseases, Conditions, Syndromes Mon, 11 Jul 2011 17:39:50 EST news229624741 A computer modeling study suggests that administering the drug ranibizumab is associated with reducing the magnitude of legal blindness and visual impairment caused by age-related macular degeneration in non-Hispanic white individuals, according to a report in the June issue of Archives of Ophthalmology. http://medicalxpress.com/news/2011-06-potential-ranibizumab-age-related-macular-degeneration.html Ophthalmology Mon, 13 Jun 2011 16:02:30 EST news227199734 In recent years, spending for glaucoma medications has increased, especially for women, persons who have only public health insurance and those with less than a high school education, according to a report published Online First by Archives of Ophthalmology, one of the JAMA/Archives journals. http://medicalxpress.com/news/2011-06-expenditures-glaucoma-medications.html Diseases, Conditions, Syndromes Mon, 13 Jun 2011 16:01:48 EST news227199689 When infants' tear ducts are blocked, the decision about when to intervene and the cost-effectiveness of doing so depend on how likely it is the problem will self-resolve, according to a report in the May issue of Archives of Ophthalmology. http://medicalxpress.com/news/2011-05-cost-effectiveness-strategies-infant-tear-duct-obstruction.html Diseases, Conditions, Syndromes Mon, 09 May 2011 16:36:41 EST news224177773
