2/11. Bone in the eye.PURPOSE: To report a case of choroidal osteoma presenting with massive subretinal hemorrhage not associated with choroidal neovascularisation (CNV). DESIGN: Case report. methods: An 18-year-old man presented with sudden loss of vision in the right eye following competitive swimming. He was found to have a massive subretinal hemorrhage involving the macula. RESULTS: Following resolution of the hemorrhage, the patient was found to have an underlying choroidal osteoma. There was no evidence of choroidal neovascularisation clinically and angiographically. He regained his normal vision. CONCLUSIONS: Choroidal osteoma presenting with massive subretinal hemorrhage not associated with underlying choroidal neovascularization need not result in poor visual outcome.- - - - - - - - - - ranking = 1keywords = neovascularization (Clic here for more details about this article) |
3/11. Choroidal osteoma: observations from a community setting.PURPOSE: To determine the characteristics of choroidal osteoma arising from a previously unreported patient population and to document new observations in this condition. DESIGN: Retrospective, observational case series. PARTICIPANTS: Eleven consecutive patients seen from 1986 through 2002 with choroidal osteoma from one community-based retina practice. INTERVENTION: Laser ablation of subretinal neovascularization in two cases and focal laser treatment of retinal pigment epithelial leaks in one case. methods: photographs, fluorescein and indocyanine green angiograms, and clinical records were analyzed. MAIN OUTCOME MEASURES: Demographic variables, visual acuity, complications of laser treatment, growth of lesions, and associated funduscopic changes. RESULTS: Choroidal osteoma from a community setting is more frequently asymptomatic (5/11 cases; 45%) than in previously reported university series, is usually initially misdiagnosed, and is not rare. light-intensity focal laser photocoagulation for serous retinal detachment unaccompanied by subretinal neovascularization can resolve fluid (1/11 cases; 9%). Laser ablation of secondary subretinal neovascularization stimulates rapid choroidal osteoma vascular remodeling (2/11 cases; 18%) and can cause retina-osteoma venous and arterial anastomoses (1/11 cases; 9%). Spontaneous choroidal hemorrhage unaccompanied by subretinal neovascularization can occur with confinement to the osteoma borders (1/11 cases; 9%). association of choroidal osteoma with retinitis pigmentosa is reported. CONCLUSIONS: These data on choroidal osteoma natural history and treatment help clinicians managing these lesions. In the community, a higher index of suspicion for choroidal osteoma is warranted.- - - - - - - - - - ranking = 4keywords = neovascularization (Clic here for more details about this article) |
4/11. Choroidal osteoma in Oriental patients.BACKGROUND: Choroidal osteoma is a rare tumour of the choroid. This is the first report of cases of choroidal osteoma in Thai patients. OBJECTIVE: To report the clinical characteristics, imaging findings and long-term follow-up of choroidal osteoma in four Oriental patients. METHOD: Four cases of choroidal osteoma were observed for 5 years or more. RESULTS: All patients were young female patients whose ages ranged from 24 to 37 years. Three were unilateral and one was bilateral. The tumors were located at the juxtapapillary and macular area with overlying serous retinal detachment. Two patients had previous thyroid diseases and one was pregnant when the tumors were diagnosed. osteoma did not develop in the vicinity of posterior staphyloma of high myopic eyes. Echography showed acoustic features of a plano-convex sonically dense lesion with high reflectivity echoes which persisted despite lower system sensitivity. None had subretinal neovascularization. subretinal fluid disappeared spontaneously within one to 14 months in three patients. Gradual growth of the tumor in a pseudopodium manner developed from two to six years after initial examination. Decalcification occurred spontaneously or after laser ablation. CONCLUSIONS: The authors presented four Oriental patients with choroidal osteoma who were observed for at least 5 years. Echography is the best method for identifying this lesion and has unique acoustic features. subretinal fluid can be seen in the absence of subretinal neovascularization and resorbs spontaneously. Decalcification occurred as a natural process or after laser ablative treatment. Hormonal changes may implicate the development of this tumor.- - - - - - - - - - ranking = 2keywords = neovascularization (Clic here for more details about this article) |
5/11. Midperipheral mottling pigmentation with familial choroidal osteoma.PURPOSE: To describe a rare presentation of familial choroidal osteoma in two siblings. methods: The clinical findings in two siblings over 4 years' follow-up. RESULTS: Two brothers (15 and 12 years old) had bilateral choroidal osteomas. Both had bilateral peripapillary yellowish-white lesions and midperipheral mottling pigment appearance, which are not seen in sporadic cases. Extensive midperipheral area with mottling pigment appearance was noted by fluorescein angiography (FA) as scattered multiple hyperfluorescent dots. The yellowish-white lesions showed diffuse hyperfluorescence with FA and hypofluorescence with indocyanine green angiography (ICG). ICG also revealed irregular hyperfluorescent areas within the tumor, indicating abnormal choroidal vessels on the tumor. In the left eye of the younger brother, the subretinal fibrosis due to choroidal neovascularization superior to the macula extended down toward the foveal region over 2 years, resulting in visual deterioration. CONCLUSION: The midperipheral mottling pigment appearance of familial choroidal osteoma cases is unique and different from most sporadic cases, suggesting that familial choroidal osteoma might have separate etiologic or modified factors.- - - - - - - - - - ranking = 1keywords = neovascularization (Clic here for more details about this article) |
6/11. argon laser photoablation of a choroidal osteoma.Choroidal osteomas are rare, juxtapapillary choroidal tumors, which are usually unilateral but can be bilateral in as many as 30% of patients. choroidal neovascularization may complicate this condition and be associated with severe visual loss. A patient treated with argon laser photocoagulation for SRNVM is described, and clinical and radiographic evidence of destruction of the osteoma during an 8-year follow-up is presented. The possible mechanisms of laser's ablative effect on bone, in addition to clinical application for choroidal osteoma treatment, are discussed.- - - - - - - - - - ranking = 1keywords = neovascularization (Clic here for more details about this article) |
7/11. review of choroidal osteoma: successful krypton red laser photocoagulation of an associated subretinal neovascular membrane involving the fovea.Laser treatment of a subretinal neovascular membrane associated with a unilateral choroidal osteoma in a 28-year-old woman is described. To our knowledge, this is the first reported use of krypton red laser photocoagulation for the initial treatment of a subfoveal neovascular membrane in this setting. Early recognition of the membrane allowed treatment prior to involvement of the central fovea. Follow-up has shown obliteration of the membrane without recurrence and 20/20 vision. We emphasize recognition of this unusual tumor, self-monitoring with an Amsler grid, and early treatment of subretinal neovascularization in this high risk group of young patients.- - - - - - - - - - ranking = 1keywords = neovascularization (Clic here for more details about this article) |
8/11. Spontaneous decalcification of a choroidal osteoma.A 23-year-old woman presented with a clearly defined, pale orange choroidal tumor superior to the right optic disc in 1976. The patient was followed. After a choroidal osteoma was first reported in 1977, this diagnosis was confirmed in this patient using ultrasonography and orbital tomography. The lesion grew very slowly over the next 5 years. In 1981, the choroidal osteoma began to thin and decalcify. Subretinal neovascularization developed in 1982 and was treated with argon laser photocoagulation. In 1983, the tumor was thinner and less calcified. During the next 18 months, it became completely decalcified and essentially disappeared leaving only a bed of pigment epithelial and choriocapillaris atrophy. This was confirmed with fluorescein angiography and ultrasonography.- - - - - - - - - - ranking = 1keywords = neovascularization (Clic here for more details about this article) |
9/11. Bilateral choroidal osteoma with subretinal neovascularization.Choroidal osteoma is a rare entity, reported previously mainly in females. We report a case of bilateral choroidal osteoma in a 15-year-old boy. ultrasonography and computerized tomography findings were key to establishing the diagnosis. During two years' follow-up, there was observable growth in the tumor size. Leakage from subretinal neovascular tufts covering the tumor caused visual deterioration. Photocoagulation of the subretinal new vessels was performed twice, with limited success, but the value of this treatment in choroidal osteomas needs further study.- - - - - - - - - - ranking = 4keywords = neovascularization (Clic here for more details about this article) |
10/11. Choroidal osteoma: two cases in Japanese women.Two cases of choroidal osteoma in otherwise healthy Japanese women are presented; the first case resembled a macular degeneration with subretinal neovascularization, the other, a diffuse amelanotic choroidal melanoma. With advanced ancillary diagnostic methods and changing concepts of prognosis and treatment of choroidal melanoma, a small atypical or doubtful choroidal melanoma should be studied carefully before hasty enucleation.- - - - - - - - - - ranking = 1keywords = neovascularization (Clic here for more details about this article) |
