Uniocular aphakia in the adult when corrected with a contact lens is in most patients no obstacle to binocular function. The long-term result is a balance between binocular function obtained and the comfort of the contact lens, and in this respect the advent of the soft lens, and especially the continuous-wear lens, appears to be most promising.

• All children who have undergone bilateral cataract operations, both those with pseudophakia and those with aphakia • People with diabetic macular oedema whose vision remains poor despite laser treatment • People with age-related macular degeneration • Children with oculocutaneous albinism • People with optic atrophy, whatever the cause • Any person who still has difficulty performing their da...

A case is reported of a young man in whom blunt injury caused a horizontal corneal tear superiorly. Aniridia, aphakia, cyclodialysis with angle recession, minimal hyphaema, vitreous haemorrhage, choroidal rupture and striae, and scleral buckling resulted. Vision improved to 6/12+.

The generation of new neurons in the adult dentate gyrus has functional implications for hippocampal formation. Reduced hippocampal neurogenesis has been described in various animal models of hippocampal dysfunction such as dementia and depression, which are both common non-motor-symptoms of Parkinson's disease (PD). As dopamine plays an important role in regulating precursor cell proliferation...
