Sequential imaging of a case of choroidal osteoma using swept-source OCT and optical coherence tomography angiography: A 4-year follow-up study

A 33-year-old gentleman was presented with metamorphopsia in the left eye due to choroidal osteoma (CO) complicated by choroidal neovascular membrane (CNVM). Optical coherence tomography angiography (OCTA) proved to be a valuable, noninvasive tool in monitoring treatment response of CNVM. The tumor subsequently underwent decalcification over a period of 4 years. In addition, SS-OCT scans were instrumental in documenting the natural course of the tumor and focal choroidal excavations (FCE), which were found in correspondence with tumor decalcification. Close follow-up is warranted in FCE, secondary to decalcification of CO, as CNVM has been documented to occur on the slope or bottom of eyes with FCE.

In vivo diagnosis of intraocular osseous metaplasia in neovascular age-related macular degeneration

A 75-year-old man presented with deterioration of right eye vision for 6 months. He had no relevant medical history. Fundus examination revealed subretinal fluid, fibrosis, and subretinal hemorrhages. Ocular coherence tomography of the right macula illustrated an underlying subretinal lesion with internal lamellae, resembling trabecular bone elsewhere in the body. Bruch's membrane was clearly intact beneath the lesion, indicating an extrachoroidal location. The lesion appeared highly reflective on B-scan ultrasonography, consistent with ossification. Although initially misdiagnosed as choroidal osteoma, this lesion represents in-vivo intraocular osseous metaplasia at the site of neovascular age-related macular degeneration. The authors believe that similar lesions may have been misdiagnosed as 揳typical� osteoma caused by failure to identify their extrachoroidal location.

Choroidal osteoma in a preterm infant

Choroidal osteoma (CO) is a rare, benign, and usually unilateral intraocular tumor composed of mature bone affecting the choroid. It appears as slightly elevated, yellowish-white, or orange choroidal mass with well-defined borders. It is commonly encountered in young female adults. Here, we report findings of a 4-week-old premature baby with CO in her left eye which was detected during a routine examination for “retinopathy of prematurity.” We believe that this case is the youngest patient reported with CO which showing that this pathology can be encountered even in a newborn.

A Case of Choroidal Osteoma with Subretinal Hemorrhage Improved by Intravitreal Bevacizumab and Aflibercept Injections

PURPOSE: To report a case of choroidal osteoma (CO) complicated by extensive subretinal hemorrhage treated with intravitreal bevacizumab and aflibercept injections. CASE SUMMARY: A 42-year-old female patient presented with decreased visual acuity and a temporal visual field defect in the left eye. The patient had a history of retinal hemorrhage in the left eye 3 years prior, which improved without any treatment. The patient's visual acuity had decreased to 0.6 at the initial visit. On fundus examination, orange-colored elevated lesions involving the superior peripapillary area with massive subretinal hemorrhage extending to the macular area were revealed. Optical coherence tomography, fluorescein angiography, and B-scan ultrasonography results indicated CO complicated by choroidal neovascularization (CNV). With multiple intravitreal injections of bevacizumab and aflibercept (bevacizumab ×1, aflibercept ×2), the patient's visual acuity improved and the CNV lesion was kept stable without recurrence as of the 1-year follow-up visit. CONCLUSIONS: Intravitreal bevacizumab and aflibercept injections can be helpful in the treatment of CO complicated by CNV, by improving visual acuity and the retinal anatomy.

Osteoma coroideo. A propósito de un caso / Choroidal Osteoma: with regard to a case

Introducción: el osteoma coroideo (OC) es un tumor benigno de la coroides, muy poco frecuente, capaz de producir auténtico tejido óseo. Afecta típicamente a mujeres jóvenes y sanas y se localiza en el polo posterior, preferentemente en la región yuxtapapilar. Generalmente es una lesión unilateral con etiología aún desconocida. Mediante la ultrasonografía y la tomografía computarizada se puede llegar al diagnóstico al demostrar la placa calcificada correspondiente a la lesión. Caso clínico: presentamos el caso de osteoma coroideo en una paciente femenina de 36 años de edad con pérdida de la agudeza visual de ojo izquierdo y antecedente de trauma ocular. En la TAC de orbita hubo una calcificación alargada de aproximadamente 7mm localizada en la región posterior superior del ojo izquierdo, aparenta yuxtapapilar, que no se modifica con el contraste en relación con osteoma coroideo. Se realizó tomografía de coherencia óptica de OI donde se evidenció elevación del EPR, posible lesión sugerente de una membrana neovascular coroidea y líquido subretinal, por lo cual se colocó 3 dosis de antiangiogénicos, mejorando la visión a cuenta dedos a 2 MT. Conclusiones: el osteoma coroideo es un tumor intraocular benigno poco frecuente, más común en pacientes jóvenes sanas cuyo diagnóstico se confirma con la calcificación visible por TAC; entre las complicaciones que producen baja visón está el desprendimiento exudativo y hemorragia, en donde está indicado terapia fotodinámica, fotocoagulación y antiangiogénicos.

Introduction: choroidal osteoma (OC) is a rare benign tumor of the choroid, capable of producing real bone tissue. It typically affects young healthy women, and it is located in the posterior pole, preferably in the juxtapapillary region. It is usually a unilateral lesion with still unknown etiology. Diagnosis can be made by ultrasonography and computed tomography by showing the corresponding calcifed plaque of the injury. Case study: we report a case of choroidal osteoma in a female patient of 36 years of age with loss of visual acuity of the left eye and a history of ocular trauma. In the TAC there was an elongated orbit calcifcation of about 7mm, located in the upper posterior region of the left eye, appears juxtapapillary, which is not modifed by the contrast in relation to choroidal osteoma. Optical coherence tomography was performed in the LE, where EPR evidenced elevation, a possible lesion suggestive of choroidal neovascular membrane and subretinal fuid, applying 3 doses of antiangiogenic, improving vision. Conclusions: choroidal osteoma is a rare benign intraocular tumor, more common in young healthy patients whose diagnosis was confrmed by CT visible calcifcation; among its complications that cause low vision is the exudative detachment and bleeding; being photodynamic therapy, photocoagulation and antiangiogenic treatment of choice.

Real-time in vivo micromorphology and histopathology of choroidal osteoma using enhanced depth imaging.

Choroidal osteoma is a usually unilateral benign tumor of the choroid composed of mature bone. Optical coherence tomography (OCT) has been used to image osteoma for several years. With the advent of enhanced depth imaging (EDI) feature of spectral‑domain OCT (SD‑OCT), better visualization of the morphology of choroidal lesions has been possible. Herein we present a case of choroidal osteoma in a 45‑year‑old woman, wherein in vivo morphology of the choroidal osteoma had been visualized using EDI technique of SD‑OCT before and after performing photodynamic therapy. EDI OCT has proven to be a valuable noninvasive imaging modality, almost comparable to histopathological examination, for diagnosing choroidal osteomas and for providing an insight into the in vivo micromorphological changes occurring during the course of the disease.

Osteoma coroideo secundario a trauma ocular / Choroidal osteoma secondary to ocular trauma

El osteoma coroideo es un tumor benigno, óseo y fue descrito por primera vez en 1978 por Gass y otros. Generalmente es unilateral, de localización juxtapapilar y más frecuente en mujeres adultas jóvenes. Presenta una etiología desconocida pero se asocian diferentes factores como: procesos inflamatorios, malformaciones congénitas, alteraciones hormonales y traumas oculares entre otros. Se presenta una paciente del sexo femenino, de 54 años de edad, con antecedentes patológicos personales de fibromialgia reumática (osteoartritis y osteoporosis) e hipertensión arterial. En los antecedentes oftalmológicos presentaba miopía leve y retinopatía arteriolosclerótica. La paciente refiere que sufrió un accidente de tránsito y recibió lesiones contusas en miembros y región periocular. A partir de ese momento comenzó con mala visión del ojo derecho y acude a nuestro servicio seis meses después. Se le realizó examen oftalmológico y los datos positivos en el ojo derecho fueron una agudeza visual de 0,4, con corrección alcanzaba 1,0 y al fondo de ojo se detecta estreches vascular, desprendimiento de vítreo posterior incompleto y una lesión blanquecina naranja de tres diámetros papilares en polo posterior que involucraba arcada temporal inferior con borde bien definidos. Se realizó angiografía que mostró hiperfluorescencia mantenida y no neovascularización; la tomografía de coherencia óptica reveló un halo de desprendimiento de retina seroso a su alrededor. El ultrasonido destaca una imagen ecogénica de alta reflexividad que involucra coroides con silencio acústico posterior. El osteoma constituye una patología no muy frecuente, cuyo diagnóstico es imagenológico, y se destaca el hecho de ser secundario a un trauma ocular.

The choroidal osteoma is a benign bony tumor described for the first time in 1978 by Gass and collaborators. It is generally unilateral, with juxtapapillary localization and more frequent in young adult females. It presents unknown etiology, but it is associated to different factors as inflammatory processes, congenital malformations, hormonal alterations and ocular traumas among others. The patient was a 54 year-old woman with a personal history of rheumatic fibromyalgia (osteoarthrosis and osteoporosis) and hypertension. Her ophthalmological antecedent showed myopia and arteriolosclerotic retinopathy. At the beginning of the year, she suffered a traffic accident and was injured in her limbs and periocular region. After this, she began feeling blurred vision of the right eye and she went to our service 6 months later. She was performed an ophthalmologic exam. It was found that the right eye had visual acuity of 0.4, and after correction it reached 1.0 .Funduscopy revealed vascular thinness, incomplete posterior vitreous detachment, and a white-orange lesion of 3 papillary diameters that involved inferior temporary arcade with well-defined borders. An angiography was performed, which showed sustained hyperfluorescence and non neovascularization; and the optic coherence tomography revealed a halo of serous retinal detachment. Additionally, the ocular ultrasound yielded a high reflectivity echogenic image that involves choroids with posterior acoustic shadow. It is for this reason that we affirm the traumatic etiology of the lesion. This is a rare pathology that should be diagnosed by imaging techniques. Notably, it is secondary to an ocular trauma.

Photodynamic Therapy Combined with Intravitreal Bevacizumab in a Patient with Choroidal Neovascularization Secondary to Choroidal Osteoma

Choroidal osteoma is a benign ossified tumor that is found predominantly in healthy young women during their second and third decades of life. The lesions are white-to-cream or orange in color, are located in the peripapillary and macular areas, and are unilateral in most patients. The symptoms of choroidal osteoma include decreased visual acuity and metamorphopsia or scotoma corresponding to the location of the osteoma, but some patients have no symptoms. Prognosis of vision varies according to tumor location, retinal pigment epithelial and sensory retinal degeneration, subretinal fluid and hemorrhage, and development of a subretinal neovascular membrane.

Combination therapy of low-fluence photodynamic therapy and intravitreal ranibizumab for choroidal neovascular membrane in choroidal osteoma.

Choroidal osteoma is an unusual form of intraocular calcification seen in otherwise healthy eyes. It is a benign idiopathic osseous tumor of the choroid, typically seen in young females. Choroidal neovascular membrane (CNVM) is a complication seen in one-third of these patients and carries a poor visual outcome. We report a case of a 25-year-old hyperthyroid female with choroidal osteoma and subfoveal CNVM in her left eye which was successfully treated using low-fluence photodynamic therapy (PDT) with verteporfin followed by a single injection of intravitreal ranibizumab.

Optical Coherence Tomography and Multifocal Electroretinography in a Patient with Choroidal Osteoma

PURPOSE: We present a case of choroidal osteoma and report a pattern of optical coherence tomography and multifocal electroretinography with a literature review. CASE SUMMARY: Using B-scan and CT, we performed OCT and MF-ERG in a patient diagnosed with choroidal osteoma. OCT revealed serous retinal detachment in the macula and a thick, irregular plate-like structure with high reflectivity in the choroidal mass lesion. MF-ERG demonstrated that Trace arrays show suppression of central and peripheral signals, especially in central lesions. Ring averages show reduced amplitudes in all locations, and 3D-topography of the response density shows marked suppression of the central signal and no foveal peak in comparison with the unaffected left eye. CONCLUSIONS: In patients with choroidal osteoma, OCT can reveal thick plate-like high reflectivity with an irregular outer surface, and MF-ERG can predict retinal dysfunction.

· AIM: To report a case of verteporfin therapy for subfoveal choroidal neovascularisation associated with choroidal osteoma.· METHODS: A 32-year-old patient was diagnosed as subfoveal choroidal neovascularisation (CNV) associated with choroidal osteoma in the right eye, with present visual acuity (VA) of 20/80; N24. He underwent 2 sessions of photodynamic therapy (PDT) in the right eye for 12mo.· RESULTS: At the end of 12mo, the patient's VA was 20/200 with complete regression of the CNV.· CONCLUSION: PDT could be a treatment option in subfoveal CNV associated with choroidal osteoma.

Atypical Choroidal Osteoma: A Case Report

The choroidal osteoma is a very unusual, benign osseous tumor of the choroid with unknown etiology. It is typically found in healthy young female in the second or third decade of life. This tumor is clinically unilateral and tend to be located in the juxtapapillary region.It appears as yellow-white to yellow-red lesion with well-defined geographic borders. The characteristic bony lesion could be demonstrated by ultrasonographic and computed tomographic examinations. We report a case of atypical choroidal osteoma located at the posterior pole of both eyes in a 7-year-old boy with chief complaints of headache and blurred vision.

Choroidal Osteoma

Choridal osteomas are benign, ossified peripapillary lesions occurring predominantly in healthy young women, They appear as yellow-white to yellow-red lesions with well-defined geographics borders. On radiologic examination, bony lesion is shown. We report herein a case of choroidal osteoma located at the posterior pole of the left eye in a 27-years-old woman the chief complaint of decreased visual acuity.

Choroidal Osteoma: Two Cases Report

Choroidal osteoma, a benign tumor and involving one eye frequently, occurred around optic disc in usually healthy young women, In our cases, the ophthalmoscopic examination revealed a sharply circumscribed, slightly elevated, orange-red subretinal lesion with irregular geographic borders and the tumors became depigmented and yellow-white with time. Diffuse and mottled depigmentation of the overlying pigment epithelium was occurred and the tufts of branching blood vessels were scattered on the tumor suface. In case 1, the tumor size was enlarged with pregnancy. In case 2, the tumor size was progressively enlarged with time in right eye and new lesion was developed in left eye, which had been normal at the first visit. The causes of visual disturbance were degeneration of retinal pigment epithelium and sensory retina in case 1 and right eye of case 2, and submacular neovascular membrane in left eye of case 2.
