Retinoblastoma is a cancer that starts in the retina, the very back part of the eye, which is a significant cause of childhood eye cancer. Unilateral incidence occurs normally non-hereditary compared to bilateral incidence. The severity is much lesser for unilateral compared with bilateral and trilateral incidence, but the primary stages are important to detect. In the UK, the incidence occurs between 40-50 children every year and the incidence occurs because of genetic mutations in RBI gene. Five years data shows that, in developed countries the disease frequency averages 95 percent compared to 50 percent worldwide and 100 percent in the UK for the period of 2006-2010. The delay in in diagnosis and access to scientists and resources are the common reasons for the differences.
The common symptom for the children affected with retinoblastoma is to lose one eye due to the progress of the tumor. The children are with higher than average intelligence possibly due to their early awareness of mortality and inner strength.
The artificial eye has been made with the preferred material known as polymethyl methacrylate (PMMA) in the UK, which is a plastic that is shatterproof and may be matched to the color of the iris.
Usually they are hand-made by a trained occularist. The eye stays in place by the muscles of the upper and lower eyelids and it can be easily removed for cleaning and regular replacement as the children grows. Research by the scientist and his team at Bournemouth University, is looking into closely improved techniques towards more accurate production and fitting of the artificial eye using a soft bonded interface at the back of the prosthetic that provides increased comfort for the wearer and still allows the important growth and stretching of the eyelids in young children.
The progress in the research in the prostheses and cancer, is more important. Decades of exploration by scientists across the world from technology, chemistry, and neurology backgrounds, in search of the ultimate comfortable prosthetic eye. If it happens our young children who are suffering with this disease will be in brighter and they are in normal prospect in life.
