“…The prevalence in our study is 12% of eyes and 15% of patients, with a mean follow-up time of 9.6 years. Our results correspond to reports by Keech et al (1989) (12.5% of eyes, mean follow-up time of 3.7 years), Mills & Robb (1994) (14.4% of eyes, 5.8 years), Robb & Petersen (1992) (15% of patients, 10.3 years), Parks et al (1993) (15% of eyes, 5.54 years) and Egbert et al (1995) (9.7% of patients, ±5 years). In contrast to these studies, Simon et al (1991) reported a higher prevalence (24% of eyes), without indicating the exact mean follow-up time (approximately 7 years) and Johnson & Keech (1996) reported a prevalence of 32% of patients with a mean follow-up time of approximately 7 years.…”

“…Chrousos et al (1984) found coexisting ocular anomalies, retained lens cortexes, and surgery for a secondary membrane to be important risk factors. In the study by Parks et al (1993) nuclear-type cataracts and microcornea seemed to be connected to complications with glaucoma.…”

“…Since an infant will likely live for 70 or 80 years after surgery, the risk becomes considerably high; however, to support this assumption, a long-term study is required. In previous studies (Chrousos et al 1984;Egbert et al 1995;Keech et al 1989;Mills & Robb 1994;Parks et al 1993;Robb & Petersen 1992;Simon et al 1991;Francois 1979;Johnson 1996), the prevalence of glaucoma varied between 5% (Francois 1979) and 32% (Johnson & Keech 1996), depending on the definition of glaucoma used, the inclusion criteria, and mean follow-up time; however, most reports on the development of aphakic glaucoma agree that it may occur any time from the early postoperative period to many years later and that lifelong follow-up is recommended (Egbert et al 1995;Simon et al 1991;Johnson & Keech 1996;Brady et al 1997;Asrani & Wilensky 1995;Phelps & Arafat 1977).…”

ABSTRACT.Purpose: To report the occurrence of postoperative glaucoma and to evaluate risk factors. Methods: Children born in four of the western counties of Sweden who were diagnosed with congenital cataracts formed a cohort (nΩ137). The following parameters were evaluated: age at cataract surgery; type of surgery; visual outcome; postoperative IOP; optic disc abnormalities; date of onset of the complication; number of reoperations, including treatment for secondary cataract; presence of systemic anomalies; microphthalmus; and eye-related anomalies. Results: A diagnosis of glaucoma was recorded for 12% of the eyes. The mean follow-up time was 9.6 years. There is a relationship between surgery before the age of 10 days and development of glaucoma. Microphthalmus is an important risk factor as well. Conclusions: Despite modern surgical techniques the incidence of aphakic glaucoma is 10% or higher. No time-dependent increase in the incidence of lateonset glaucoma between the 1980s and the 1990s could be proven.

“…Glaucoma developing after early cataract surgery is more problematic (Phelps & Arafat 1977;Chrousos et al 1984;Simon et al 1991;Parks et al 1993;Mills & Robb 1994;Egbert et al 1995;Walton 1995). It can occur soon after surgery as a result of pupil block or several years later with an open, but abnormal angle (Russell-Eggitt & Zamiri 1997).…”

ABSTRACT.Purpose: To study the type and frequency of complications requiring additional surgery in infants operated on for congenital cataract before 12 months of age. Methods: The medical records of 57 infants who underwent surgery for unilateral and bilateral congenital cataracts during a five-year-period were reviewed retrospectively. The follow-up period ranged from 9 to 70 months with a mean of 37 months. Cataract extraction was performed on 83 eyes. Results: Thirty-eight operations for after-cataracts were performed on 32 out of 83 eyes. Fourteen vitrectomies were made on 11 eyes because of pupillary block glaucoma. Glaucoma requiring trabeculectomy developed in eight eyes 2 to 14 months after cataract extraction. This type of glaucoma occurred almost exclusively in eyes operated on during the first two months of life. Conclusion: Complications requiring additional surgery are very common in infants operated on for congenital cataracts during the first year of life. Glaucoma requiring trabeculectomy developed particularly in infants who had their cataract extraction very early. Glaucoma development was not more common in infants operated on for after-cataract.Key words: infant -cataract surgery -complications -aphakic glaucoma -after-cataract.Acta Ophthalmol. Scand. 1999: 77: 677-680 Copyright c Acta Ophthalmol Scand 1999. ISSN 1395-3907 C ataract is the most important cause of treatable childhood blindness (Foster et al. 1997). The visual outcome in infants undergoing surgery for congenital cataract has improved dramatically since the advent of modern surgical techniques and the realisation that early intervention and immediate optical correction can prevent otherwise irreversible deprivation amblyopia (Taylor 1979;Jacobson et al. 1981). However, it is extremely important that the cataract extraction and the correction of aphakia are performed early -within the first months of life Rogers et al. 1981;Gelbart et al. 1982;Parks 1982;Birch & Stager 1988;Drummond et al. 1989;Kugelberg 1992). It is also important to diagnose and treat complications such as after-cataract and secondary glaucoma as soon as possible to avoid deprivation amblyopia or damage of the optic nerve. Both open-angle and closedangle glaucoma occur after successful surgery for congenital cataracts and the incidence remains alarmingly high (Phelps & Arafat 1977;Keech et al. 1989;Simon et al. 1991;Mills & Robb 1994).The aim of this retrospective study was to determine the type and incidence of complications requiring additional surgery in infants who had undergone cataract extraction prior to 12 months of age. Material and MethodsThe medical records of all infants who underwent surgery for congenital cataract before 12 months of age at St. Erik's Eye Hospital during the five-year period from October 1991 to August 1996 were reviewed retrospectively. Seventy-five percent of the operations were performed by the same surgeon, the remaining twenty-five percent by three other surgeons.The surgical technique of the cataract extraction was th...
