The most common causes of blindness and low vision are cataract, refractive errors, glaucoma, diabetic retinopathy, and retinopathy of prematurity. A variety of treatment is available ranging from spectacles, contact lenses and low vision aids to surgical treatment such as corneal transplantation and osteo-ordonto-keratoprosthesis. Vocational and navigation rehabilitation will help these people to learn adaptive techniques and skills that let them maintain an independent lifestyle and improve their quality of life.
The DHA concentration is high in retinal and brain membrane phospholipids, and it is involved in visual and neural function and neurotransmitter metabolism.2 During the last trimester, the fetus accrues about 50 to 70 mg a day of omega-3 fatty acid, DHA. Both maternal DHA intake and circulating DHA concentrations are important determinants of fetal blood concentrations of DHA. Babies accrue DHA into the CNS up until about 18 months of age.
