Research on optic nerve regeneration is at a relatively early stage. However, there are ongoing clinical trials of cell-based and other therapies for optic nerve damage from various causes.
You will find several such trials at www.clinicaltrials.gov. In addition to searching keywords at this site, you can search for specific conditions, study locations, and other criteria using the �Advanced Search� page at https://www.clinicaltrials.gov/ct2/search/advanced. ClinicalTrials.gov is updated frequently and we encourage you to check often. Note that you may find clinical trials that charge a fee for patients to enroll. While this is legal in many countries, including the United States, you should exercise caution when considering participation in such a trial.
Developing a regenerative therapy to treat diseases and injuries of the optic nerve is a priority for the NEI Audacious Goals Initiative (AGI). One AGI project is developing a new tool to examine the optic nerve, without the need for biopsy, to see if investigational treatments are working (see https://projectreporter.nih.gov/project_info_description.cfm?aid=8912809). Please refer to https://nei.nih.gov/audacious/ for more information and regular updates about the AGI.
