Purpose: To report on the clinical presentation and surgical treatment (procedure and outcome(s)) of glaucoma in children with facial port wine stain. Materials and methods: This is a retrospective chart review of children with facial port wine stain referred to Alexandria University paediatric ophthalmology practice from 2005 to 2016. The charts of 22 children (44 eyes) with facial port wine stain were reviewed. The data extracted included demographics, results of ophthalmic examination findings and treatment(s). The main outcome measures were the number of eyes stratified as glaucoma, glaucoma suspects and no glaucoma at the initial and final presentations. Results: The average age of presentation was 18.2 (±33.9) months. After a follow-up of over 16.1 (±24.8) months, there were 34%, 30% and 36% of the study eyes diagnosed as glaucoma, glaucoma suspects and no glaucoma, respectively with mean ± standard deviation of intraocular pressure of 20.6 ± 5.1, 13.6 ± 5.4 and 7.5 ± 1.7 mmHg. The majority (91%) of eyes presenting with glaucoma had clear corneas. In total, 11 eyes were operated upon for glaucoma. The recorded success rate was 91%. Two eyes developed a postoperative exudative choroidal detachment, of which one resolved spontaneously and the other was successfully managed by intravitreal gas injection. Conclusion: Glaucoma is a significant ocular hazard in children with facial port wine stain that may not be evident on the initial presentation. The presentation is usually with a clear cornea and surgical intervention is associated with a high success rate and a low rate of complications.
Purpose: To report on the changes in the natural crystalline lens in primary congenital glaucoma (PCG) eyes that had undergone previous combined angle-filtering surgery with antimetabolites. Settings: The pediatric ophthalmology unit of the ophthalmology department of Alexandria Main University Hospital. Design: A retrospective chart review. Methods: A retrospective chart review of patients presenting with and operated (by combined angle-filtering surgery with antimetabolites) for PCG in the period from 2005 to 2018. Any lens pathology was noted as well as the management and the outcome. Results: The records of 422 children (613 eyes) were reviewed. Lens pathology was noted in 54 (8.8%) eyes. Abnormalities in lens clarity (cataract) were detected in 31 (56%) eyes, and abnormalities in lens position (subluxation) were detected in 24 (44%) eyes. Management options included observation (in 28 eyes), lensectomy for aphakia (in 14 eyes), lensectomy with in the bag intraocular lens (IOL) implantation (in 11 eyes), and lensectomy with iris-fixated IOL (in 1 eye). Elevation of intraocular pressure (IOP) occurred in only 4 eyes (of 26 operated eyes, 15.3%) after lens extraction. Conclusions: Changes in the natural crystalline lens clarity and/or position occurred in 8.8% (54 of 613) of PCG eyes operated by combined anglefiltering surgery with antimetabolites. Lens extraction was a relatively safe procedure with only 15% (4 of 26) of eyes suffering an elevation of IOP after lens extraction.
Purpose A horizontal corneal diameter greater than 2 standard deviations from the mean (9.8 mm) or greater than 11 mm in term infants defines megalocornea (herein referred to as a large clear cornea). The aim of the current study was to report on the incidence and clinical characteristics of children presenting with large clear cornea that do not suffer glaucoma. Methods A retrospective chart review of children presenting with large clear cornea to the pediatric ophthalmology unit of the ophthalmology department of Alexandria Main University Hospital in the period from March 2011 to December 2020 was conducted. A large clear cornea was defined as a horizontal white-to-white corneal diameter (as measured by calipers) greater than 12 mm. Glaucoma was diagnosed according to the childhood glaucoma research network (CGRN) criteria and the axial length was used to filter out eyes with large clear corneas due to congenital high myopia. Results Out of 120 eyes of 91 (58 males) children a total of 76 eyes of 67 (41 males) children were diagnosed with glaucoma and 44 eyes of 24 (17 males) children (36.7%) did not suffer glaucoma. Out of these, 30 eyes were classified as myopia and 14 eyes as congenital megalocornea. Conclusions More than one third of eyes presenting with large clear corneas may not have glaucoma, and almost two thirds of these eyes (that are not suffering from glaucoma) demonstrate axial myopia.
