Purpose: To report 3 cases providing insight into clinical progression of reactive retinal astrocytic tumor. Methods: The clinical, imaging, and when available, the cytologic features of 3 cases of reactive retinal astrocytic tumor (focal nodular gliosis) were reviewed. Results: A 6-year-old female, a 49-year-old man, and a 39-year-old man each developed a white retinal mass associated with laser photocoagulation, lattice degeneration, and treatment of a presumed vascular tumor, respectively. All tumors were white, circumscribed retinal masses that tended to be associated with exudation and either initially or eventually minimal vascularity. Conclusion: Reactive retinal astrocytic tumor can be observed in response to a degenerative, inflammatory, or ischemic retinal insult. Such tumors may progress after therapeutic intervention.
