Choroidal Osteoma????

Question

My daughter is 18 and was just told that she may have an choroidal osteoma in her left eye. This is a very rare condition. She is scared & so am I. Please no mean comments.Is there anyone out there who has this condition or has heard of it??

Thanks so much!

That certainly is not a happy diagnoses.  I hope it turns out to be something else.  This is the best definition I have of Chorodial Osteoma. I hope it helps, remember it is information only.  Your doctor is the best person to give you the answers YOU need.  Take care. :)

Choroidal osteoma is characterized by bone in the choroidal vascular layer of the eye. These bone deposits are more likely to be found near to the optic nerve.

When your eye care professional looks into your eye, a typical choroidal osteoma will appear like a yellow subretinal tumor near the optic nerve. Pigment can be seen to dust its surface. The choroidal osteoma typically has well defined scalloped edges. Hemorrhage near the edge of a choroidal osteoma suggests the presence of subretinal neovascularization.

Photography is used to document the choroidal osteoma size and shape. Baseline photographs are helpful for subsequent evaluations for growth and neovascularization.

Fluorescein angiography: Since a choroidal osteoma is made of bone, when fluorescein dye circulates through the eye, it will be slow to penetrate the tumor. Once the fluorescein dye is inside the choroidal osteoma, it also has trouble getting out. This is why the fluorescein pattern of choroidal osteoma is one of slow uptake and persistent "late" fluorescence.

Ultrasound: Ultrasound examination of an eye with a choroidal osteoma will demonstrate intense reflectivity from the tumor and shadowing of the posterior orbital contents. If the intensity (gain) of the ultrasound machine is decreased, the eye-care specialist is likely to see persistent reflectivity or “brightness” from the tumor. Ultrasound can also be used to measure the thickness of a choroidal osteoma.

Computed radiographic imaging: Computed axial tomography (CT) can be particularly helpful to see the calcification of a choroidal osteoma in unusual cases.
