    Abstract:
    OBJECTIVE: To report the clinical characteristics, long-term follow-up and management of choroidal osteoma. METHODS: Eighteen eyes of 12 cases (5 male and 7 female) of choroidal osteoma were studied. Best corrected vision, intraocular pressure, perimetry, anterior segment and eye fundus were examined routinely. Special tests included phytochrome of eye fundus, fluorescein angiography and/or indocyanine green angiography; B-ultrasonogram, CT, perimetry and electrophysiology. (1) Eight eyes of 6 cases treated with vitamins and anti-inflammatory drug and followed-up periodically for 1-26 years (median 2.5 years). (2) Four eyes of 2 cases were treated with Krypton laser photocoagulation, 2 of them were superimposed with transpupillary thermotherapy (TTT). (3) TTT was given primarily for 6 eyes of 4 cases with infrared dione laser; the spot size was 3 mm, 1-5 spots were conducted conjunctly to cover the tumor surface. Power was 800-1200 mw at 60-90 seconds. The procedure was completed in 1-3 recessions with an interval of 4-6 weeks. RESULTS: (1) In the medical treatment group, gradual growth of the tumor with pseudopodium along the margin was disclosed. One eye showed spontaneously regression during the long-term follow-up. (2) Laser photocoagulation was effective for 2 eyes, but residual flat serous detachment around the optic disc persisted in another 2 eyes and subsided with TTT. (3) Choroidal osteoma complicated with CNV treated primarily with TTT, prominent improvement was demonstrated. CONCLUSIONS: Choroidal osteoma grows gradually in the natural course and shows pseudopodial margin. Laser photocoagulation was effective for certain cases. TTT is a method of choice either used primarily or supplementary after laser photocoagulation, it is recommended for cases complicated with CNV.
