Anterior segment ischemia changes can occur without detachment of any muscles. The most common cause of such ischemic changes of the anterior segment is the removal of too many rectus muscles in one operation. Twenty dog eyes and eight monkey eyes were subjected to the disinsertion and detachment of various combinations of extraocular muscles. They were sacrificed at intervals from 30 to 90 days. During the observation period, they were observed for gross and slit lamp changes. The enucleated eyes were studied microscopically for signs of ischemic and necrotic changes. Two patients who were studied, observed, and treated for anterior segment ischemia following muscle surgery are described. The changes which occur after muscle surgery are extensive and include corneal edema, cataract, chemosis, corneal changes, decreases in intraocular pressure, decreases in outflow or glaucoma and frank necrosis. The variables which lead to this reaction is described in detail. Also, some unanswered queries, such as the duration of the reaction and the time interval of the reaction after multiple muscle surgeries, are discussed.

Anterior staphylomas developed in two young patients as a postoperative complication of hyphema extractions through corneoscleral sections. The patients, aged five and nine years, underwent evacuation of the hyphemas after rebleeding caused medically unmanageable intraocular pressure elevations. Postoperatively, both patients received corticosteroids and had elevation of intraocular pressure. To repair the staphyloma, a scleral overlay patch graft was performed in one patient, but the intraocular pressure remained elevated and the staphyloma gradually recurred. Enucleation of the eye was eventually required. Resection of the staphylomatous area with lensectomy and complete vitrectomy was performed in the second patient. After four years of follow-up this patient continues to do well.

Anterior uveitis in children can present difficult management problems. While the course of the inflammation may defy the usual treatment modalities, attention to five specific areas of clinical management may enable the ophthalmologist to better preserve visual function. Careful examination, proper adjustment of corticosteroid dosage, repeated intraocular pressure measurement, patient compliance, and adequate follow-up are the areas discussed.

A nine-month-old girl with nonketotic hyperglycinemia and bilateral enlargement of the corneas is reported. There was no evidence of elevated intraocular pressure or iridocorneal angle anomalies. The corneas have remained clear and lusterous without tears in Descemet's membrane. The possibility that the elevated glycine level may play a part in the buphthalmia of this patient is discussed in light of what is known about the effect or excessive dietary glycine on the developing chick eye. Further ophthalmologic study of patients with various forms of glycinemia might provide further understanding of the ways in which the developing eye may enlarge.

A 10-year-old retarded child was seen by an ophthalmologist because of strabismus. Examination of the optic nerve heads revealed cupping consistant with glaucoma and initiated a referral. The appearance of this girl, with flat-broad based thumbs and toes, small head, low set ears, high arched brows, antimongoloid slant to the eyes, high arched palate, associated with mental retardation, and strabismus suggested the Rubinstein-Tabyi Syndrome. Gonioscopy revealed a high iris insertion, while tonometry indicated mildly elevated pressures in the right eye. Examination of the optic nerve heads showed large glaucomatous type cups, more so on the right with compromise of the temporal rim. Trabeculectomy was effective in controlling the intraocular pressure in the right eye. The association of juvenile glaucoma with the Rubinstein-Taybi Syndrome requires that ophthalmic referral to assess glaucoma be an essential part of the evaluation.

A computerized topographic analysis system was used to evaluate corneal changes after strabismus surgery in eight eyes of five patients with Graves' disease. All patients underwent inferior rectus muscle recession; three eyes also had medial rectus recession. Corneal topographic analysis revealed that, postoperatively, corneas steepened inferiorly and inferotemporally at 1.5 mm from corneal apex (p less than 0.05). The opposite effect was observed in the superior quadrant (average flattening of 1.20 +/- 0.32 D at 1.5 mm from corneal apex, and 1.08 +/- 0.39 D at 3.0 mm from corneal apex; p less than 0.05). Superotemporally, the cornea flattened by an average of 0.65 +/- 0.26 D at 3.0 mm from corneal apex, and superonasally 0.72 +/- 0.19 D at 3.0 mm from corneal apex (p less than 0.05). Central, nasal, and temporal cornea did not show statistically significant changes. Spherical equivalent did not change significantly after surgery. The amount of restriction and upgaze measured preoperatively was correlated weakly with inferior corneal steepening (r2 = 0.44; p = 0.046). These results are indicative that corneal topography may be influenced by strabismus surgery for Graves' disease through alteration of extraocular muscle tension or intraocular pressure.

The age-related trend values and the normal intraocular pressure (IOP) increase curve from birth through the 16th year of life were studied in 460 subjects with a noncontact tonometer (Keeler Pulsair, Keeler, Ltd, Windsor, Berks, UK). Much lower values than in adults were recorded in subjects up to the age of 3 or 4 years. This finding leads us to believe that in the treatment of infantile glaucoma IOP should be kept within the age physiologic levels, in an attempt to prevent visual field loss and optic atrophy.

Graves' thyroid ophthalmopathy primarily affects women in their third through sixth decade. Sixty-seven patients with clinical myopathic ophthalmic Graves' disease examined (by SCB) between 1982 and 1989 were measured for changes in upgaze intraocular pressure and strabismus. Special attention was paid to "masquerade" symptoms, including pseudosuperior oblique palsies and cyclotorsions. Any correlation between the extent of hypertropia on muscle exam and upgaze intraocular pressure changes is examined. Data suggest that significant changes in introcular pressure in upgaze correlate with more severe extraocular muscle involvement, may represent progression to muscle fibrosis, and occur uniformly in our study of patients who progress to require inferior rectus recession.

An adequate pupillary aperture is required for accurate ophthalmoscopy and retinoscopy in pediatric aphakia. When pupillary miosis does not respond to pharmacologic dilation, optical iridectomy performed with a vitreous suction-cutting instrument under general anesthesia may be required. We report a 27-month-old aphakic child whose pupillary aperture was enlarged from 1 mm to 3.5 mm with neodymium (Nd):YAG pupilloplasty, following intramuscular sedation with meperidine, promethazine, and chlorpromazine. Removal of the laser chin rest and positioning of the patient on a table with adjustable height facilitated delivery of 140 applications at 2.5 to 4.3 mJ to the pupillary border. Levobunolol 0.5% controlled the transient posttreatment rise in intraocular pressure. We suggest that Nd:YAG pupilloplasty performed with sedation be considered as an alternative to intraocular surgery when pupillary miosis in pediatric aphakia does not respond to dilating agents.

We examined intraocular pressures of patients with strabismus whose eyes were instilled with corticosteroid eyedrops after a strabismus operation. Group A consisted of 11 children under 10 years of age whose eyes were instilled with 0.1% dexamethasone; Group B consisted of nine patients 10 years old or older whose eyes were instilled with 0.1% dexamethasone; and Group C consisted of 13 children under 10 years of age whose eyes were instilled with 0.1% fluorometholone. In Group A, four patients had intraocular pressures greater than 30 mm Hg, five had intraocular pressures from 21 to 30 mm Hg, and two had intraocular pressures under 21 mm Hg one or two weeks postoperatively. The intraocular pressure decreased to less than 21 mm Hg one week after discontinuation of dexamethasone treatment in all nine patients. No patients in Groups B or C had intraocular pressures greater than 20 mm Hg. Our results suggest that marked ocular hypertensive response to 0.1% dexamethasone treatment occurs frequently in children under 10 years of age.
