Surgical treatment of Duane's syndrome.

Nineteen patients undergoing treatment for Duane's syndrome are reported. The patients were treated with appropriate horizontal muscle recession in order to relieve abnormal head position or a significant tropia in primary position. Success rate in eliminating the abnormal head position was 79% while 100% were significantly improved. No overcorrections occurred despite large recessions. Retraction in adduction was reduced in each case. Motility of the eye was not increased following recession and in no case was fusion ability or stereopsis affected. The elimination of abnormal head position appears to be stable for periods up to 8.75 years. Postoperatively, patients obtained approximately 30 degrees of binocular visual field including primary position. Other surgical techniques in treating Duane's syndrome are discussed.

Pediatric aphakic glaucoma.

Three cases of pediatric open-angle aphakic glaucoma are presented. These patients had congenital cataracts extracted by the extracapsular techniques of phacofragmentation or irrigation and aspiration. Each required a secondary membranectomy and had development of glaucoma six to 25 months after cataract extraction. Surgical therapy was required in each case of glaucoma, and multiple procedures were necessary. Visual outcome in the involved eye was less than 20/400. The cause of the open-angle aphakic glaucoma is most likely secondary to damage to the trabecular meshwork initiated by uveitis and lens remnants. We urge ophthalmologists who perform pediatric cataract surgery to use phacofragmentation of the cataract and posterior capsule and anterior vitrectomy with vitrectomy instrumentation. This should reduce the incidence of secondary membranes and glaucoma. Ophthalmologists should be aware of this complication and the necessity of prolonged patient follow-up.

Posterior chamber intraocular lenses: long-term results in pediatric cataract patients.

Major problems in pediatric cataract patients include noncompliance with contact lenses resulting in amblyopia. Advances in intraocular cataract surgery have provided a better environment to perform intraocular lens (IOL) implantation in children. We prospectively analyzed the results of 34 consecutive pediatric patients who underwent cataract removal and insertion of an IOL. Operative technique performed was posterior scleral beveled or frown incision and IOL endocapsular fixation. Subgroups included 10 eyes with traumatic cataract, and 24 eyes with developmental cataracts. Six patients had bilateral IOLs. Data presented in each subgroup included initial and final visual acuity, age, sex, type of cataract, A and B scan biometry, early and late postoperative complications, time of YAG capsulotomy, postoperative refractive correction, and state of binocular vision. Preoperative visual acuity ranged from 20/70 to light perception. The success rate for postoperative visual acuity of 20/40 or better occurred in 29 of 34 eyes, or 85.3%. In the traumatic cataracts, 8 of 10 eyes (80%) obtained 20/40 vision or better. In developmental cataracts, 21 of 24 eyes (88%) achieved visual acuity of 20/40 or better. Amblyopia (three patients) or macular scar (two patients) accounted for reduced visual acuity in the five eyes with vision less than 20/40. Early complications included posterior synechiae and lens deposits. The primary late complication was opacification of the posterior capsule in 18 of 34 eyes. The average time for YAG capsulotomy post-cataract removal was 17 months. None of the 28 patients (34 eyes) developed glaucoma, IOL dislocation, or other significant postoperative problems related to IOL insertion.(ABSTRACT TRUNCATED AT 250 WORDS)
