M.; Dutton, G. N. Abstract: The bleb which develops following trubeculectomy may be diffuse or cystic in nature. Cystic blebs can he complicated by infection, leakage of aqueous, astigmatism and problems related to contact lens wear, whereas diffuse blebs are not associated with such problems. We report a preliminary prospective photographic evaluation of bleb formation following each of three types of conjunctival incision: (a) fornix bascd (b) straight limbus based and (c) curved limbus based. The vascular patterrn and morphology of the drainage bleb formed was dependent upon the type of conjunctival incision made. The fornix based flap was found most likely to give rise to a diffuse bleb with a normal vascular pattern.

A.; Baiyeroju, A. M. Abstract: Children with Congenital Heart Disease (CHD) presenting for non-cardiac surgery have various physiological and functional abnormalities and thus pose great challenges to the anaesthetist. This one year prospective study was undertaken to determine the incidence of CHD in children presenting for noncardiac surgery, the type of lesions and anaesthetic course. Five patients (1.5%) out of a total of 324 children aged from birth to twelve years who had surgery during the study period were found to have CHD, ventricular septal defect (VSD) being the commonest cardiac lesion. Surgery was for cataract extraction and herniorrhaphy. Although all the children had been previously treated or were on current treatment for additional medical problems, surgery under closely monitored balanced general anaesthetic technique was found to be safe.

Abstract: Ocular complications occurred in 28%, of children with head injury. Neuro-ophthalmological lesions made up one-third or these complications, mostly involved the optic nerve, and were associated with other focal neurological signs more frequently than non-neural ocular complications. Lesions or the posterior visual pathways were rare but tended to be permanent. 1991-01-01T00:00:00Z http://ir.library.ui.edu.ng/handle/123456789/2742 Title: A comparison of visual function scores in hydrocephalic infants with and without lumbosacral myelomeningocoele Authors: Shokunbi, M. T.; Odebode, T. O.; Agbeja-Baiyeroju, A. M.; Malomo, A. O.; Ogunseyinde, A. O.; Familusi, J. B. Abstract: Purpose: The cerebrum is frequently malformed in children with myelomeningocoele. This anomaly renders them potentially susceptible to cerebral visual impairment. In these patients, hydrocephalus is an important and frequent complicating lesion which compromises intellectual function and may also cause cerebral visual impairment. In this study, we determined whether hydrocephalic patients with lumbar myelomeningocoele (HLM) are at a greater risk of visual impairment than hydrocephalic patients without this lesion (H). Methods: In this prospective study, we assessed five parameters of visual function in 20 hydrocephalic children with lumbar myelomeningocoele and compared the total visual function scores (TVFS) obtained with those from hydrocephalic children without overt spinal dysraphism, but similar in age, sex and ventricular size. The parameters, which were assessed with the aid of a quantitative grading scale, were papillary size and reaction, optic atrophy, visual fixation and tracking. Results: The age and sex distributions of the patients in the two groups were similar. The anterior and posterior dimensions of the lateral ventricles were also similar. The mean (SD) of the TVFS were 24.25 (3.63) and 24.20 (3.47) respectively for the two groups (P = 0.90). Conclusions: The results suggest that, in hydrocephalic infants with lumbar myelomeningocoele, visual function is not further diminished by the associated dysraphism and that ventricular dilatation is the major determinant of visual impairment. 2002-01-01T00:00:00Z
