The present disclosure provides adeno-associated virus (AAV) virions with altered capsid protein that binds heparan sulfate proteoglycans, where the AAV virions exhibit greater infectivity of retinal cells, altered tropism and/or the ability to bind and cross the inner limiting membrane following intravitreal injection. The present disclosure further provides methods of delivering a gene product to a retinal cell in an individual, and methods of treating ocular disease.
