INTRODUCTION: Available data on traumatic cataract in Asian children is primarily confined to South Asian countries. We aimed to describe the demographics, nature of injury and visual outcomes of Malaysian children with traumatic cataract from a suburban area, and discuss the literature on Asian children with this condition.
METHODS: We conducted a retrospective study of 29 children below 17 years of age who were diagnosed with traumatic paediatric cataract and who attended Hospital Universiti Sains Malaysia, Kelantan, Malaysia, between January 2000 and December 2010. Follow-up periods ranged from 12 to 120 months. Demographic data, clinical features, mechanism and extent of injury, and final visual outcome were recorded.
RESULTS: The study population was predominantly male. The right eye was injured in 62.07% of patients. A majority of patients had penetrating injuries, with the most common cause being injury by an organic foreign body (24.14%). Presenting visual acuity worse than 6/60 was observed in 68.97% of patients. Only 34.48% of patients had a final corrected visual acuity of 6/12 and better. 55.18% of patients were operated on within less than one month of their injuries. A majority of children sustained concurrent injuries to the anterior segment structures. Corneal opacity and amblyopia were the most common causes of poor final visual acuity.
CONCLUSION: Health education and awareness are essential tools that can prevent avoidable blindness due to traumatic cataract in the paediatric population. The importance of rehabilitation programmes for these patients should be emphasised.
Limited data are available on optic neuritis in Asian children. Clinical profiles tend to vary with different races. We aimed to determine the clinical manifestations, visual outcomes, and etiologies of optic neuritis in Malaysian children, and discuss the literature of optic neuritis in Asian children. A retrospective study involving 14 children with optic neuritis was performed at Hospital Universiti Sains Malaysia between July 2005 and January 2010 (follow-up, 18-60 months). Clinical features, laboratory results, possible etiologies, and visual acuity after 1 year were studied. Females were predominant (mean age at presentation, 11.1 years). All patients manifested bilateral involvement. Swollen optic discs were observed in 92.9% of eyes; 60.7% of patients demonstrated a visual acuity of 6/60 (or 20/200) or worse on presentation, whereas 14.3% remained at 6/60 (or 20/200) or worse, 1 year after their attack. Cecocentral scotoma comprised the most common visual field defect. Infection contributed to 50.0% of cases; 14.3% progressed to multiple sclerosis during follow-up, with no evidence of recurrent optic neuritis. The clinical profiles and etiologies of optic neuritis in Malay children differ slightly compared with other optic neuritis studies of Asian children. The frequency of progression to multiple sclerosis is relatively lower.
There are limited data concerning the optic disc topography in normal-tension glaucoma (NTG) and primary open-angle glaucoma (POAG) patients living in Southeast Asian countries. This study aims to compare optic disc parameters in patients with NTG and POAG in Malaysia and to discuss the results in comparison with studies of NTG and POAG in other Asian countries.
