Why is a sub-Tenon’s steroid injection performed?
A sub-Tenon’s steroid injection (STS) is an office procedure performed to decrease inflammation, swelling, or leaky blood vessels inside the eye. The steroid medicine acts to decrease inflammation and leakage from blood vessels from a variety of causes, thereby offering the opportunity for improvement in vision. The effect of STS lasts for several months after which repeated injection may be considered if necessary.
How is a sub-Tenon’s steroid injection performed?
Anesthetic solutions are used to make the procedure pain-free. A pressure sensation is often felt as the steroid is injected next to the eye with a very thin, short needle. The procedure is brief.
Will the injection affect my vision?
The vision may be slightly blurred immediately after an injection. The anticipated improvement in vision occurs slowly over a period of weeks to months. Sometimes, the pressure inside the eye increases and may require eye drops for several months. There may also be an increased rate of cataract formation. It is common for the upper lid to droop slightly; this improves over several months. Rare risks of steroid injection include bleeding, infection, retinal detachment, glaucoma, and loss of vision. Please report any severe loss of vision to the doctor without delay.
How do I care for the eye after injection?
If a patch is placed on the eye, keep it on as directed by the doctor, usually 2-3 hours. You may be given eye drops and instructions on how to use them. Physical activity is not limited after STS. Tylenol or Ibuprofen may be used if there is discomfort after the injection, but severe pain should be reported to your doctor without delay. It is normal to experience a red area on the white of the eye, which disappears in one to two weeks. If you have any questions or concerns, please call the office.
