Choroidal osteoma with neovascular membrane and associated hemorrhages.
lesions regress spontaneously, whereas others continue to enlarge. Annual review with fundus photography and/or fluorescein angiography is recommended to detect neovascularization, or changes in size or appearance (which may be suggestive of a previously undiagnosed malignant lesion).
Laser Choroidal neovascularization is treated with laser photocoagulation; several sessions may be required. Neovascularization at the macula is occasionally treated with photodynamic therapy (see Age-related macular degeneration).
