CT Scan

Question
Why would my mother have been told she needs a CT scan done of her eyes?

She has Glaucoma (both eyes) and has also been diagnosed with PVD.

Thanks


Answer
I have a suspicion what was recommended was not exactly a regular CT scan, but rather scanning laser ophthalmoscopy.  Such tests go under the brand names of equipment - OCT, GdX, HRT.  These tests are commonly done for glaucoma.  They document the amount of nerve tissue (nerves that give you vision) that is present.  Over time they let the doctor see if nerve tissue is being lost due to the glaucoma, and whether the treatment being recommended is effective.  If this test was recommended for your mother, she should go ahead and have it done.  The information gained is very useful in managing glaucoma.
