Managing strabismus in endocrine eye disease.

In Graves' ophthalmopathy, now considered a separate autoimmune disorder, 15% of patients have a motility disorder. This is usually a restrictive strabismus, most often involving the inferior rectus muscle, and is diagnosed with the aid of forced duction testing, saccadic velocity measurement, binocular visual field testing and prism cover testing. Adjustable sutures may be used, depending on the intraoperative findings. The case presentations in this paper demonstrate the principles of diagnosis and treatment.

Diplopia following Jones tube placement.

Diplopia following Jones tube placement is a rare complication. A 67-year-old female with diplopia was treated four months after Jones tube placement by incising conjunctival tension bands. To the best of our knowledge, this is the first report of treatment of this problem.

Intermittent exotropia: is surgery necessary?

Sixty cases of intermittent exotropia were studied to compare the outcome of those patients treated medically with the outcome of those patients treated surgically. Below 30 prism diopters of intermittent exotropia, there is a high functional cure rate in both groups. Preoperative orthoptics did not lead to a surgical overcorrection. And finally, central fusion is not essential for a clinical cure.

The four-step test for diagnosis of paralytic and/or restrictive strabismus.

By placing four diagnostic steps in a logical sequential manner, the diagnosis of a paralytic or restrictive deviation is made somewhat easier. Each time an incomitant strabismus is presented to an ophthalmologist, the four-step procedure should be used. Versions, ductions, and the cover test will reveal the eye to be investigated. Saccades, forced ductions, and/or forced generations will determine the problem and direct a surgical approach if needed.

An unusual case of ophthalmoplegic migraine.

A 33-year-old man complaining of headache and diplopia lasting one hour or less and occurring weekly was found to have ophthalmoplegic migraine. He was treated unsuccessfully with propranolol HCl, ergotamine tartrate, and methysergide maleate.

Comparative study of the surgical management of congenital esotropia of 50 prism diopter or less.

Fort-nine patients with congenital esotropia of 50 prism diopters or less were selected at random. Twenty-five had bimedial recessions performed initially followed by bilateral rectus resections when needed. Twenty-four had recession/resections performed initially and when needed, were followed by the same procedure on the fellow eye. The average corrections obtained after first procedure and after second procedure were compared and analyzed. The results showed the initial procedures of both groups to be equally effective. The results obtained after the second procedure in the recession/resection group were significantly better. Therefore, it would appear that for the patient we have described, the most effective surgical approach is ultimately the surgical regimen of recession/resection followed by the same procedure on the fellow eye.

Experimental creeping muscle.

Using healthy rabbits, medial and lateral rectus muscles were recessed. Classical Swann incisions, along with limbal incisions with and without conjunctival recession, were performed. The second variable of reactability of suture material, utilizing absorbable 6-0 chromic and nonabsorbable 6-0 tycron sutures, was tested. Using a 9-0 nylon marking suture for documentation of area of recession, anterior advancement could be accurately measured. Five months after surgery, the animals were sacrificed, and each muscle was examined. Regardless of incision perfored and regardless of suture type used, no anterior advancement of retroplaced muscles occurred.

See-saw nystagmus after strabismus surgery.

A 7-year-old child underwent craniotomy for a craniopharyngioma. One month later she developed a divergence excess type exotropia and had strabismus surgery 11 months later. The day after strabismus surgery, the parents noted abnormal eye movements that represented see-saw nystagmus. The patient had a small esotropia after surgery, but it was found that stimulated convergence controlled the nystagmus. This case illustrates the dual central and ocular influence on the development of see-saw nystagmus.

Epikeratophakia on pediatric traumatized corneas.

Four children ranging from 4 to 6 years of age with unilateral aphakia and corneal scarring secondary to penetrating injuries were treated with epikeratophakia. One child had undergone a rotational penetrating keratoplasty to displace the corneal scar from the visual axis prior to the epikeratophakia procedure. In all of the cases, nonlyophilized donor tissue was utilized. The procedure was successful in all four cases. The average best corrected postoperative visual acuity was 20/45. These results confirm prior studies suggesting that epikeratophakia can be performed successfully on partially opaque and scarred corneas in pediatric aphakic eyes.

Goniotomy with sodium hyaluronate.

A modification of the classical goniotomy technique is described. After complete evacuation of the anterior and posterior chambers, sodium hyaluronate is placed in the anterior chamber and on the cornea. Putting hyaluronate in both locations prevents the formation of air bubbles under the goniotomy lens, provides the same index of refraction on both sides of the cornea, prevents accidental loss of the anterior chamber, and allows maximal depth of the anterior chamber. Diminished intraocular bleeding and lower risk of injury to the corneal endothelium, iris, and lens may be additional advantages of the procedure. Two cases are presented in which five goniotomies were performed on four eyes using this technique. Both patients had one eye controlled with a single goniotomy. The fellow eye of each patient required multiple procedures. Glaucoma was controlled successfully with no medication in all four eyes. No significant complications occurred.

Pediatric ocular trauma: a retrospective survey.

A retrospective, cross-sectional survey was conducted of all pediatric trauma cases seen by the ophthalmology department at our institution from January 1986 to December 1991. The study included 504 patients who were 15 years old or younger. The purpose of this study was to determine risk factors for ocular injury, especially injury resulting in severe visual impairment, and to identify trends and preventable causes. Our results were consistent with the findings of other similar studies: male patients predominated, penetrating injuries resulted in poor visual outcomes, and many of the causes of severe visual deficit were preventable with more adequate adult supervision.

Mesoectodermal dysgenesis: familial iris anomaly.

A family is described with hypoplasia of the anterior iris stroma, no angle anomalies, and no glaucoma. The pedigree is suggestive of an autosomal dominant mode of inheritance. This is compared to the main peripheral malformations of the anterior chamber cleavage syndrome and other disease entities with similar iris changes. The pedigree represents a point on the continuum of mesoectodermal dysgenesis or anterior chamber cleavage syndrome.
