Corticosteroid-induced glaucoma is a well-recognized phenomenon in adults, but not children. We describe an infant who developed juvenile glaucoma with buphthalmos while receiving systemic steroid treatment. The intraocular pressure normalized several months following discontinuation of treatment.
BACKGROUND: Few cases of corneal perforation in a premature infant have been described in the literature. METHODS: Identical twins were born at 30-weeks gestation. One twin developed a corneal epithelial defect, infiltration, and perforation with extrusion of intraocular contents, requiring an emergency penetrating keratoplasty. The second twin developed a progressive corneal opacity, requiring a lamellar keratectomy. RESULTS: After penetrating keratoplasty, the patient developed absolute glaucoma with buphthalmos, leading to enucleation. The twin's lamellar keratectomy specimen proved to be a dermoid. CONCLUSIONS: One must be aware of the danger of the development of spontaneous corneal perforation with extrusion of intraocular contents in premature infants presenting at birth with an epithelial defect.

The standard approach to a three-port to pars plana vitrectomy is by placing the sclerotomies in the superotemporal and superonasal quadrant and the infusion port in the inferotemporal quadrant. This approach may be adjusted in selected cases that exhibit structural abnormalities of the globe at the superior site by placement of the sclerotomies in the temporal quadrants. We describe a case of a buphthalmic eye with a huge filtering bleb from previous glaucoma surgery that successfully underwent combined cataract and vitreoretinal surgery from a temporal approach for the repair of a giant retinal tear with cataract.
Four cases of Recklinghausen disease are presented with different clinical manifestations. The diagnosis in each case was established on NIH Consensus Statement criteria. The last case is a controversial one concerning the type of neurofibromatosis.
This case documents unilateral congenital glaucoma associated with congenital lower lid entropion. A 2-year-old female infant was referred for evaluation and treatment of right-side buphthalmos caused by congenital glaucoma associated with bilateral congenital lower lid entropion that was prominent on the right side and present at birth. Examination disclosed a lower eyelid entropion of the right side that was treated surgically by reinserting the disinserted retractor aponeurosis to anterior inferior tarsal border. After three weeks, the patient was successfully treated with primary combined trabeculotomy-trabeculectomy for congenital glaucoma. The entropion of the left lower lid was asymptomatic and did not require any surgery. Buphthalmos caused by congenital glaucoma may be associated with congenital lower lid entropion and the association may be causal or coincidental.
After scraping the epithelium from the rabbit's cornea, pseudoeosinophilic leucocytes appeared in the limbic area within one hour and began to advance, presumably by means of pseudopodia, into the anterior corneal stroma. The cytoplasmic granules of these cells were intensely stained by eosin and by the Undritz peroxidase method during the first hour, but were not stained by the PAS method until the eighteenth hour. Electron microscopy failed to show crystalloids in the granules. The cellular changes were followed until the fourth day, by which time most of the cells had disappeared by fragmentation, karyorrhexis and lysis.
Experimental glaucoma was produced in 50% of rabbit eyes by injecting 75 units of alphachymotrypsin into the posterior chamber. The elevation of intraocular pressure was stable, rarely exceeded 50 mm Hg, and lasted one year or longer. Progressive buphthalmos first appeared 2 to 3 weeks following injection of the enzyme. Ocular histologic changes included bullous keratopathy, iris and ciliary body atrophy, and cupping of the optic disc. The optic nerve became atrophic but no cavernous degeneration occurred. In the retina there was thinning of the nerve fiber layer and loss of ganglion cells with preservation of the other retinal elements. The mechanism leading to glaucoma following alphachymotrypsin injection is unclear. This study demonstrated formation of peripheral anterior synechiae and reduction of outflow facility within 2 weeks following injection and these factors may play a role.
We report the first described association of natal teeth with congenital hydrocephalus and congenital glaucoma, anterior segment dysgenesis with non-attachment of the retina. The clinical findings support a diagnosis of Walker-Warburg syndrome. The forkhead 7 transcription factor gene is proposed as a candidate gene for this syndrome.
PURPOSE: Evaluation of the influence of intraocular pressure (IOP) after trabeculectomy on the axial length and refraction of eyeballs in children with primary congenital glaucoma. MATERIAL AND METHODS: Thirty six eyes of 23 children at the age from 7 days to 6.5 years (mean 17.1 months), were examined. Measurements of corneal diameter, axial length, IOP and refraction were done before trabeculectomy and in the long-term follow-up (mean 7.9 years) after surgery. RESULTS: Horizontal corneal diameter didn't change and ranged from 10 to 15 mm, mean 13.22 mm. Mean value of axial length before trabeculectomy was 22.45 mm and 23.27 mm at last visit. The difference was statistically significant. The axis decreased in 3 eyes, was the same in 3 eyes. In the others the eye growth changed proportionally to the age of child. IOP values were statistically lower after surgery (mean 16 mmHg) than before treatment (mean 35.51 mmHg). There was no correlation between IOP and axial length of eyeballs (p = 0.69) and between IOP and refraction changes (p = 0.42) in the long-term follow-up. CONCLUSIONS: There is small influence of normalised IOP after trabeculectomy on size of eyeballs and refraction in children with primary congenital glaucoma. The development of eyeballs even buphthalmic is proportionally to the age.
