retrobulbar surgery

For some eyeball retractions, mild eyeball atrophy, and some patients who are not suitable for hydroxyapatite hemisphere implantation, post-ball filling surgery may be an option to improve appearance. Eyeball retraction: refers to the eyeball invagination caused by the loss or atrophy of the sputum, and the eye movement is basically normal. Some patients have severe sacral wall fractures, and the movement of the eyeball is obviously limited. At this time, the soft tissue in the sac tends to have a heavier scar and adhere to the wall of the eyeball. The filling of the ball cannot make the eyeball protrude forward. In addition, the post-ball filler may oppress the posterior nerve vessels and affect vision, so the vision is considered to be less than 0.1. Treatment of diseases: ocular trauma to eye burns Indication 1. Eyeball invagination: refers to the eyeball invagination caused by the loss or atrophy of the fat, and the eye movement is basically normal. Some patients have severe sacral wall fractures, and the movement of the eyeball is obviously limited. At this time, the soft tissue in the sac tends to have a heavier scar and adhere to the wall of the eyeball. The filling of the ball cannot make the eyeball protrude forward. In addition, the post-ball filler may oppress the posterior nerve vessels and affect vision, so the vision is considered to be less than 0.1. It is necessary to fully explain the condition before surgery. 2, mild eyeball atrophy: some patients have mild eyeball atrophy, but the cornea is still clean and transparent, the eye is very stable, no red, pain and other symptoms, you can consider keeping the eye. Atrophy of the eye is a very individualized pathological process, and the rate and extent of atrophy is sometimes unpredictable. Clinically, we found that those with eye injury caused by anterior segment injury, the cornea will shrink very quickly, those with eye injury caused by injury to the posterior segment of the eye, the eyeball may have been significantly reduced, and the size of the cornea is acceptable, those due to The eyeball atrophy caused by some internal eye diseases is lighter. 3, recurrent orbital depression after ocular implantation: some patients have done orbital filling, but the orbital sag still exists, the original ocular surface material is not hydroxyapatite, can not do hydroxyapatite hemisphere Into the surgery (such as silicone ball, can not provide blood for the hemisphere implant, can not be integrated with it), and the position of the eye table is still good, it is a pity to take it out, you may also try to fill the ball after the method. Contraindications 1, with systemic diseases, can not tolerate surgery. 2, local infection, not suitable for surgery. Preoperative preparation Antibiotics are routinely used before surgery.
