The prevalence of ocular abnormalities was studied in 165 children from a Malaysian school for the deaf. Ninety-five children (57.6%) had one or more ocular abnormalities. Rubella retinopathy was the commonest form of ocular abnormality (35.2%). Refractive errors were found in 23 children (13.9%). Refractive errors in the rubella group were significantly more common than in the non-rubella group of deaf children (p < 0.001) (chi 2 test). Thirteen children had congenital anomalies causing significantly impaired vision. Ophthalmological examination of deaf children helps in the detection of cases with rubella eye signs and thus helps to identify the cause of deafness. Since deaf children are at greater risk of visual and ocular abnormalities, periodical ophthalmological examination should be carried out in these children.
This paper reviews the subject of tuberous sclerosis complex and presents data in eight cases of this condition, admitted to Hospital Universiti Sains Malaysia over a period of 8.5 years. The average age at presentation was 53 months. Seizures were the most common presenting feature. Male to female ratio was 3:1. Family history was present in four patients. All of the patients had one or more skin lesions. Six of them had retinal in six patients. Two patients had renal angiomyolipomas. A high index of hamartomas. Cardiac tumours were found in two patients. Multiple subependymal hamartomas were detected in six patients. Two patients had renal angiomyolipomas. A high index of suspicion and a detailed physical examination is required to diagnose this rare disorder.
Few attempts have been made to determine the risk factors for diabetic retinopathy which is a major cause of visual impairment and blindness. One hundred and forty patients of diabetes mellitus were studied to determine the prevalence and types of retinopathy, and its relation to various risk factors. Nearly half (48.6%) of the patients suffered from retinopathy. The significant associated risk factors were long duration of diabetes, proteinuria and elevated serum creatinine level. However, there was no significant association between the prevalence of retinopathy and high levels of serum cholesterol, C-peptide levels, associated hypertension, and glycaemic control of diabetes mellitus. An effective screening programme for detection of retinopathy in the patients of diabetes as a regular practice is encouraged.
