    Abstract:
    BACKGROUND: The pathogenesis of open-angle glaucoma and ocular hypertension in patients who have undergone surgical correction of their congenital cataracts remains undetermined. This study examines the prevalence of glaucoma and ocular hypertension in a population of patients who did not undergo surgical correction of their pediatric cataracts. METHODS: Fifty-eight eyes of 41 patients had cataracts before 2.5 years of age and were followed up until at least 5 years of age without operative correction. The patients were studied for the following parameters: age at diagnosis, type of cataract, etiology, bilaterality, optic nerve head cup-to-disc ratio, intraocular pressures, and reason why the patient did not undergo an operation. Glaucoma was defined as the presence of glaucomatous optic nerve head cupping with intraocular pressures of greater than 22 mm Hg. Ocular hypertension was defined as intraocular pressures greater than 22 mm Hg with no optic nerve changes. RESULTS: Nine of the 58 eyes had cataracts caused by persistent hyperplastic primary vitreous. The average age to the last intraocular pressure measurement was 19 years (range 5 to 48 years). Closed-angle glaucoma developed in two patients with persistent hyperplastic primary vitreous. Neither open-angle glaucoma nor ocular hypertension developed in any patients. CONCLUSION: Pediatric cataracts not of the persistent hyperplastic primary vitreous type were not associated with ocular hypertension or glaucoma in the absence of surgical cataract correction. In eyes with persistent hyperplastic primary vitreous cataracts, spontaneous closed-angle glaucoma developed in two of nine patients and open-angle glaucoma developed in none. Surgical cataract correction, or the aphakic state that follows such operations, may be responsible for pediatric aphakic glaucoma.
