The CMGs offer information on the diagnosis and management of a range of conditions that present with varying frequency in primary and first contact care.
Sub-tarsal Foreign Body (STFB) is a painful condition in which specks of dust or other debris become embedded in the tarsal conjunctiva. It can cause vertical abrasion tracks on the cornea. Symptoms include acute foreign body sensation, pain, lacrimation and eye reddening. This Clinical Management Guideline outlines the aetiology, signs and symptoms and evidence-based recommendations for diagnosing, managing and treating STFB. It provides recommendations for non-pharmacological management including how to remove foreign bodies, and pharmacological treatment approaches.
What is sub-tarsal foreign body?
Sometimes a speck of dust or other debris, landing on the eye, becomes trapped under the upper eyelid. While there it may cause discomfort which increases on blinking when the foreign body is rubbed over the eye surface. Usually the patient will know that something has blown into the eye.
How is sub-tarsal foreign body managed?
The optometrist will turn the upper eyelid over and, if a foreign body is found, remove it. Sometimes a drop of local anaesthetic is needed to reduce the discomfort of this procedure. Generally, no further treatment is needed, but if there is a large abrasion of the surface of the cornea (the clear window at the front of the eye) or any evidence of infection, a course of local antibiotic drops or ointment may be prescribed. Such cases are not usually referred to the ophthalmologist.
