New results from a prospective clinical trial conducted in France show that children with low-risk retinoblastoma do not need postoperative (adjuvant) chemotherapy to prevent disease recurrence or metastasis; the results also suggest that certain patients with intermediate-risk disease can receive less aggressive adjuvant treatment, or perhaps forego it altogether. Avoiding chemotherapy spares patients from treatment side effects and long-term health risks, such as cardiovascular disease and development of a second cancer. http://medicalxpress.com/news/2013-03-prospective-children-retinoblastoma-safely-adjuvant.html Cancer Mon, 04 Mar 2013 16:00:03 EST news281624036 Zebrafish, the staple of genetic research, may hold the answer to repairing damaged retinas and returning eye-sight to people. http://medicalxpress.com/news/2013-01-zebrafish-retinas-eyesight-people.html Ophthalmology Thu, 31 Jan 2013 11:33:59 EST news278854432 Blindness is often caused by corneal diseases.
