Suprascleral removal of a foreign body from the retrobulbar muscle cone in two dogs.

The successful application of a suprascleral approach to remove a foreign body within the retrobulbar muscle cone in two dogs is described. The episcleral space was entered through a small opening in the paralimbal conjunctiva and bulbar vagina. Under ultrasound guidance, a curved haemostat with a fine tip was advanced along the scleral surface to the foreign body, which was then carefully grasped and removed using gentle traction. The conjunctival incision was left to heal secondarily. The suprascleral approach may allow the quick removal of non-cutting and non-barbed foreign bodies from the episcleral space or the retrobulbar muscle cone, without the need for extensive tissue dissection. To reduce the risk of damaging extraocular tissues, the procedure must be performed cautiously and under ultrasound guidance. The globe should be continuously observed for any movement suggesting traction or pushing forces on bulbar or adjacent anatomical structures.
