Strabismus after retinal detachment surgery.

In conclusion, we can summarize our experience as follows: Exoplants oriented radially and wherever placed can be productive of important degrees of astigmatism and diplopia. In our experience, they are often associated with torsional diplopia; Surgery under the rectus muscles may be responsible for adhesions and limitations of excursion of the globe; Anteriorly placed exoplants, especially those placed under the rectus muscles and particularly temporally or below, are apt to erode the overlying muscle sheath and tendon; a muscle so eroded may sometimes be found reattached to the globe just posterior to the exoplant; Repeated surgical intervention, perhaps in association with careless or inaccurate closure of the periocular tissues, Tenon's fascia and conjunctiva, may be important factors in the production of strabismus; Factors which have not been responsible for strabismus as far as we can tell are encircling elements without exoplants and intraoperative detachment and reattachment of the extraocular muscles. I know of no instance where these alone have been productive of an important postoperative strabismus.
