Retrobulbar anesthesia in strabismus surgery. II. Use of a short-acting anesthetic agent.

Forty-two patients underwent strabismus surgery with a retrobulbar injection of 3% chloroprocaine hydrochloride. In the 18 patients who were followed up in the immediate postoperative period, the average duration of action of 3% chloroprocaine was found to be 2.13 hours. In addition to the advantages of local anesthesia, this short-acting anesthetic permits earlier modifications of adjustable sutures and the earlier discharge of patients on the same day as surgery.

Large bimedial rectus recessions in congenital esotropia.

The success rate of large (6 and 7 mm) bimedial rectus recessions in 45 congenital esotropes with deviations of 50 prism dioptres or greater was found to be 91%. Judgment of final alignment was made six weeks postoperatively, with an average follow-up of 13 months. Large bimedial rectus recessions are an effective surgical treatment for congenital esotropia. This procedure does not significantly alter adduction, and leaves other muscles available should further surgery be necessary. These findings show that initial surgery on three or more muscles is unnecessary in congenital esotropia.

Aphakic correction in ectopia lentis.

Ectopia lentis may cause a reduction in visual acuity, which varies with the type and degree of dislocation and the presence of other ocular abnormalities. Retinoscopy may reveal a significant refractive error, usually myopia and astigmatism. Occasionally, an accurate refraction may be difficult because of tilting or dislocation of the lens. If aphakic refraction improves visual acuity, an aphakic correction should be considered.

Retrobulbar anesthesia in strabismus surgery.

Forty-nine patients, ranging in age from 12 to 77 years, underwent strabismus surgery under local anesthesia. With standard preoperative medication and a retrobulbar injection of 2% mepivacaine hydrochloride (hyaluronidase added in 12 patients), effective anesthesia was obtained. Twenty-four patients were observed during the immediate postoperative period, and return of extraocular muscle function and visual acuity was found to be complete an average of 3.8 hours after the injection. The addition of hyaluronidase significantly altered the duration of the anesthetic. Local anesthesia may be a preferable technique in terms of decreased morbidity, especially in the older patient. The short duration of anesthesia and lack of side effects also enable the surgeon to use adjustable sutures and make the final adjustment relatively early in the postoperative period.
