    Conjunctival incisions for trabeculectomy and their relationship to the type of bleb formation-A Preliminary Study
    (1987-04) Agbeja, A. M.; Dutton, G. N.
    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.

    Non-cardiac surgery and anaesthesia in children with congenital heart disease
    (1996-06) Soyannwo, O. A.; Baiyeroju, A. M.
    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.

    Ocular complications of head injury in children
    (Springer-Verlag, 1991) Shokunbi, T.; Agbeja, A.
    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.

    Congenital poikiloderma with unusual hypopigmentation and acral blistering at birth
    (Elsevier, 1999) Ogunbiyi, A. O.; Ogunbiyi, J. O.; Baiyeroju-Agbeja, A. M.
    Congenital poikiloderma is an uncommon hereditary disorder. It has been reported in association with various synuromes. No case has previously been reported from this environment. We report a case of congenital poikiloderma in a two and a half year old female Nigerian associated with unusual generalised hypopigmentation and acral blisters at birth. The child subsequently developed macular hyperpigmentation on an erythematous background and atrophy of the skin. Although he had some features which were suggestive of Rothmund-Thomson syndrome (RTS), the presence of nypopigmentation at birth along with acral blistering, was noted to be peculiar to this child. We, therefore, feel that this case presents a distinct variant of congenital poikiloderma that has not been described previously.

    The relationship between ventricular size and visual function in children with hydrocephalus
    (1998) Odebode, T. O.; Shokunbi, M. T.; Malomo, A. O.; Familusi, J. B.; Agbeja-Baiyeroju, A. M.; Ogunseyinde, A. O.
    We examined the relationship between ventricular size and visual function in 50 children (36 males and 14 females) with hydrocephalus. The third and lateral ventricular sizes and the visual function scores did not significantly differ between the sexes. Ventricular enlargement was most pronounced at the trigones and least at the level of the foraminae of Monro. The visual function score correlated inversely with the size of the lateral ventricle measured at the levels of the anterior horn and the trigone and expressed as coronal diameter and "Modified" Evans' ratio (r = 0.49; P = 0.001 and r = - 0.38, P = 0.01 for the anterior horn; r = 0.48, P = 0.00 I and r = -0.35, P = 0.001 for the trigone). The size of the third ventricle did not correlate with visual function score. A "modified" anterior Evans ratio of 0.60 and a trigonal Evans ratio of 0.73 were associated with very low visual function score. Furthermore, there was significant inverse correlation between occipitofrontal circumference (OFC) and visual function (r = -0.6379, P = 0.001), but OFC was not valuable for predicting visual function before the onset of head enlargement.

    Practical aspects of ophthalmic ultrasound in Ibadan
    (1995-08) Marinho, A. O.; Baiyeroju-Agbeja, A. M.; Fatukusi, J. I.; Kalejaye, O.; Sogo, K.
    Objective: To highlight the clinical usefulness and the practical aspects of ophthalmic ultrasonography, Materials and Methods: We have described the practical aspects of ophthalmic ultrasonography and reviewed the results of over 200 ophthalmic ultrasounds in our hands. Result: Using ultrasonography, the normal eye is globular and measure 18-24mm in anterior posterior view. The vitreous chamber is c1ear of reflection. Various intraocular lesions like cataracts, debris, vitreous haemorrhage, retinal detachment, panophthalmitis and foreign bodies as well as retro-ocular masses were diagnosable using ophthalmic ultrasonography, Conclusion: Ophthalmic ultrasonography is recommended as all adjunct to the diagnosis of eye diseases as it is painless. in-expensive and gives accurate results.

    Bilateral orbital rhabdomyosarcoma mimicking burkitt's lymphoma
    (1998) Falade, A. G.; Osinusi, K.; Baiyeroju-Agbeja, A. M.; Ogunbiyi, J. o.; Owoeye, J. F. A.; Thomas, J
    Bilaterial orbital rhabdomyosarcoma mimicking Burkitt's lymphoma in an 11-year old girl is reported. The patient presented with bilateral proptosis and right cervical lymphadenopathy. Despite consultations at a number of hospitals, a definitive diagnosis was not made until presentation at the University College Hospital, Ibadan, where cytological examination of a fine needle aspiration biopsy specimen of the tumour and the lymph node revealed. changes that were consistent with those seen in rhabdomyosarcoma. This case emphasises the fact that rhabdomyosarcoma is an important differential diagnosis of orbital tumours in childhood, especially in Burkitt's lymphoma endemic areas.

    Causes of removal of the eye In Ibadan
    (1996-12) Baiyeroju-Agbeja, A.; Ajibode, H. A.
    The aim of the study was to enumerate the causes of removal of the eye in our community and find out ways of reducing this. 139 eyes were removed at the University College Hospital, lbadan, over a 5 year period between January 1989 and December 1993. Only 100 of the cases were available for inclusion in this study. The age, sex, causes of removal of the eyes and final diagnosis were obtained. Most of the patients (64%) were below the age of 30 years, the youngest being 3 weeks of age. The most common cause of eye removal was found to be infective (endophthalmitis/panophthalmitis), although in the age group of 0-10 years, Retinoblastoma was the commonest cause of the removal of the eye.

    Screening for retinopathy of prematurity in Ibadan
    (1998-08) Baiyeroju-Agbeja, A.; Omokhodion, S. I.
    Between January to June 1995, a prospective study was carried out to determine the incidence and severity of retinopathy of prematurity (ROP) in newborn infants of less than 1,500g birthweight or less than 31 weeks gestational age. 18 babies were eligible for inclusion in this study and only one developed ROP, a Stage 1, Zone III disease i.e. 5.5% of babies at risk. In spite of the low incidence compared with other studies', it is advisable to continue the collaboration between opthalmologists and neonatologists to prevent babies at risk from developing untreatable ROP, thereby increasing the number of blind children in our society.
