Long-term follow-up of solitary hemangioma of the choroid.

Three cases of solitary hemangioma of the choroid are reported. One patient, followed for 22 years, was untreated, and the natural course was chronic and progressive. Although the tumor itself did not enlarge markedly, the serous detachment of the retina was extensive. Cystoid degeneration and deterioration of visual acuity was the final result. Two patients were treated with argon green laser and then followed for eight years and one year, respectively. Laser photocoagulation is the method of choice. Clinical characteristics and differential diagnosis are discussed. Early diagnosis and early treatment are important for preserving vision in an eye affected with hemangioma of the choroid.
