Recently someone complained about being charged £10 for an OCT scan at a well known opticians. It was certainly worth the money for me. The optometrist noticed changes from my previous annual scan, some swelling of the nerves and a slight bleed. She advised me to go to A&E to have it checked out. After some tests including a CT scan with dye, they found I have central venous thrombosis. I am in hospital being monitored further and having blood thinning injections. Apart from an unremarkable sinus type headache around my left eye, I was unaware there was anything wrong. I could have had a stroke, lost my sight or worse! I am very grateful to the optometrist who was very knowledgeable and diligent.
The causes are uncertain, it can be a history of clotting or use of the contraceptive pill. When I looked it up, there was also some mention of vasculitis so I was wondering if it could be linked to PMR or to taking prednisilone?
