Lysosomal storage diseases represent a group of about 50 genetic disorders. The deficiencies of lysosomal and non-lysosomal proteins cause an accumulation of compounds which are normally degraded within the lysosome. There are currently no therapeutic options to cure patients suffering from a lysosomal storage disease. Due to their progressive nature there is considerable morbidity and mortality. Thus, an early treatment to maintain major systemic functions is of utmost importance. While so far only symptomatic therapies are in use, the newly available enzyme replacement therapies offer a real causal approach for selected storage diseases. Many of these disorders are characterised by pathognomonic eye findings. Therefore, the ophthalmological examination provides the opportunity for an early and non-invasive diagnosis and a chance to initiate early treatment. This review is intended to give a survey of the most common lysosomal storage diseases, particularly with regard to ophthalmological changes as well as illustrate new therapeutic options.
