Trends in Eye Removal Surgeries at a Tertiary Care Hospital Over Three Decades.

PURPOSE: To determine the trends in eye removal surgeries at a tertiary hospital in Nigeria over 26 years. METHODS: A retrospective comparative review of clinical records of all patients who had eye removal surgery at a tertiary hospital in Ile-Ife, Nigeria, between 2014 and 2019 was done. Patients' demographic and clinical data, including indication for eye removal and type of surgery were analysed and compared with two earlier studies at the same hospital between 1994 and 2013. RESULTS: There was an average of 14.3 surgeries per year between 2014 and 2019. Patients' ages ranged from 2 to 102 years, M:F was 1.5:1, the commonest indication for eye removal was infection (n=30, 34.9%), and the most common surgery was evisceration (n=70, 81.4%). Studies from 1994 to 2003 and 2005 to 2013, reported an average of 9.2 and 10 surgeries per year; ages ranging from 4 days to 88 years and 3 months to 88 years; with a M:F of 2.1:1 and 3.4:1 respectively. In both studies, the commonest indication for eye removal was trauma (43.4% and 43.8% respectively) and the most common surgery was enucleation (57.6% and 55% respectively). Trend data showed a progressive increase in eye infections (12% vs 15% vs 34.9%) and eviscerations (19.6% vs 31.2% vs 81.4%) over time. CONCLUSION: There was a change in trend towards an increase in eviscerations and infective indications for eye removal at the hospital over three decades. Prompt and optimal treatment of orbito-ocular infections is recommended to reduce the incidence of eye removal surgeries.

BUT: Déterminer les tendances des chirurgies d'ablation de l'oeil dans un hôpital tertiaire du Nigeria sur une période de 26 ans. MÉTHODES: Un examen comparatif rétrospectif des dossiers cliniques de tous les patients ayant subi une chirurgie d'ablation de l'œil dans un hôpital tertiaire d'Ile-Ife, au Nigeria, entre 2014 et 2019, a été effectué. Les données démographiques et cliniques des patients, y compris l'indication de l'ablation de l'œil et le type de chirurgie, ont été analysées et comparées à deux études antérieures menées dans le même hôpital entre 1994 et 2013. RÉSULTATS: Il y avait une moyenne de 14,3 chirurgies par an entre 2014 et 2019. L'âge des patients allait de 2 à 102 ans, le rapport M:F était de 1,5:1, l'indication la plus courante pour l'ablation de l'œil était l'infection (n=30, 34,9%), et la chirurgie la plus fréquente était l'éviscération (n=70, 81,4%). Les études menées de 1994 à 2003 et de 2005 à 2013 ont fait état d'une moyenne de 9,2 et 10 interventions chirurgicales par an, d'âges allant de 4 jours à 88 ans et de 3 mois à 88 ans, et d'un rapport M:F de 2,1:1 et 3,4:1 respectivement. Dans les deux études, l'indication la plus courante pour l'ablation de l'œil était le traumatisme (43,4 % et 43,8 % respectivement) et la chirurgie la plus courante était l'énucléation (57,6 % et 55 % respectivement). Les données sur les tendances ont montré une augmentation progressive des infections oculaires (12 % vs 15 % vs 34,9 %) et des éviscérations (19,6 % vs 31,2 % vs 81,4 %) au fil du temps. CONCLUSION: On constate un changement de tendance vers une augmentation des éviscérations et des indications infectieuses pour l'ablation des yeux à l'hôpital sur trois décennies. Un traitement rapide et optimal des infections orbitooculaires est recommandé pour réduire l'incidence des chirurgies d'ablation des yeux.

Epidemiology and Management of Oculoplastic Disorders at a Tertiary Hospital: A 4-Year Review.

PURPOSE: To describe the epidemiology and management of oculoplastic disorders at a tertiary hospital in Nigeria. METHODS: This was a retrospective review of patients with oculoplastic disorders at the Department of Ophthalmology, Obafemi Awolowo University Teaching Hospitals Complex, IleIfe, Nigeria from January 2013 to December 2016. The general ophthalmology service records were reviewed to identify patients with oculoplastic disorders. Data retrieved from patient records included date of initial visit, age at presentation, gender, oculoplastic diagnosis and aetiology, modality of treatment given, and indications for patient referrals. RESULTS: There were 563 (7.4%) patients with oculoplastic disorders, out of 7,575 ophthalmology department patients. They had 573 oculoplastic disorders in all. There were 281 (49.9%) males and 282 (50.1%) females. The median age at presentation was 28 years (range, 1 day to 100 years). Eyelid laceration (n=68; 11.9%) and chalazion (n=63; 11%) were the commonest disorders. Trauma (n=125; 21.8%) was the commonest aetiology, followed by inflammatory (n=121; 21.1%) and infective (n=108; 18.8%) causes. There were 162 (28.3%) surgical interventions; eyelid repair (n=67; 41.4%) was the commonest, followed by evisceration (n=25; 15.4%), and excisional biopsy (n=25; 15.4%). No patient had ptosis or lacrimal surgery. Orbital disorders (n=21; 42.9%) were the commonest indication for a referral elsewhere. CONCLUSION: Eyelid laceration was the commonest oculoplastic disorder, trauma was the commonest aetiology, and eyelid repair was the commonest oculoplastic surgery done. Further training in oculoplastics with emphasis on ptosis, lacrimal and orbital surgery, as well as the provision of equipment needed for optimal oculoplastic service delivery are recommended.

OBJECTIF: Décrire l'épidémiologie et la gestion des troubles oculoplastiques dans un hôpital tertiaire du Nigeria. MÉTHODES: Il s'agissait d'un examen rétrospectif des patients atteints de troubles oculoplastiques au département d'ophtalmologie, Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife, Nigeria, de janvier 2013 à décembre 2016. Les dossiers du service d'ophtalmologie générale ont été examinés afin d'identifier les patients souffrant de troubles oculoplastiques. Les données extraites des dossiers des patients comprenaient la date de la première visite, l'âge au moment de la présentation, le sexe, le diagnostic oculoplastique et l'étiologie, la modalité du traitement administré et les indications pour le renvoi des patients. RÉSULTATS: 563 (7,4 %) des 7 575 patients du service d'ophtalmologie présentaient des troubles oculoplastiques. Ils présentaient 573 troubles oculoplastiques au total. Il y avait 281 (49,9%) hommes et 282 (50,1%) femmes. L'âge médian à la présentation était de 28 ans (intervalle de 1 jour à 100 ans). Paupière (n=68 ; 11,9%) et le chalazion (n=63 ; 11%) étaient les troubles les plus courants. Le traumatisme (n=125 ; 21,8%) était l'étiologie la plus fréquente, suivie par les causes inflammatoires (n=121 ; 21,1%) et infectieuses (n=108 ; 18,8%). Il y a eu 162 (28,8 %) interventions chirurgicales ; la réparation de la paupière (n=67 ; 41,4 %) était la plus courante, suivie de l'éviscération (n=25 ; 15,4%) et de la biopsie excisionnelle (n=25 ; 15,4%). Aucun patient n'a subi de ptose ou de chirurgie lacrymale. Les troubles orbitaux (n=21 ; 42,9%) étaient l'indication la plus fréquente d'un renvoi ailleurs. CONCLUSION: La lacération de la paupière était le trouble oculoplastique le plus courant, le traumatisme était l'étiologie la plus courante et la réparation de la paupière était la chirurgie oculoplastique la plus courante. Il est recommandé de poursuivre la formation en oculoplastie en mettant l'accent sur le ptosis, la chirurgie lacrymale et orbitale, ainsi que de fournir l'équipement nécessaire à une prestation optimale des services oculoplastiques.

Chemopreventive and remediation effect of Adansonia digitata L. Baobab (Bombacaceae) stem bark extracts in mouse model malaria.

ETHNOPHARMACOLOGICAL RELEVANCE: Adansonia digitata L. Baobab (Bombacaceae) solvent extracts have been reported to possess medicinal properties and are currently been used traditionally for the treatment of malaria and several other diseases and infection; however few reports exist in literature that provides supportive scientific evidence in favour of its medicinal use. AIM OF THE STUDY: This study investigated the efficacy of Adansonia digitata stem bark extract in offering protection against experimental malaria and also examined its remediation effect when administered after established infection. MATERIALS AND METHODS: Weanling albino mice were used in the study. The mice were transfected intraperitonially with an inoculums size of 1× 107 of chloroquine susceptible strain of plasmodium berghei infected erythrocytes. Mechanisms of action of the extract were investigated by measuring the degree of tissue peroxidation and tissue antioxidant status. Severity of malaria was determined by measuring the serum C-reactive protein (CRP), tumor necrosis factor-alpha (TNF-α), and serum and tissue Alkaline phosphatase (ALP) activity. RESULTS: There was a significant increase in serum CRP, TNF-α concentrations and serum and tissue ALP activity in the control mice following Plasmodium berghei infection. All the treatment had effect on the growth of Plasmodium berghei parasites in mice. The extracts showed a significant dose dependent increase packed cell volume (PCV), percentage chemosupression/clearance and a significant decrease in percentage parasitemia at the two doses when administered after established infection. Methanolic extract (MEAD) at 400mg/kg exhibited the highest chemosupressive activity. The extract significantly reduced the degree of tissue peroxidation, increased the level of reduced glutathione (GSH), catalase and superoxide dismutase activity. Administration of the extract after established infection reduced serum CRP and TNF-α concentrations and serum and tissue ALP activity. CONCLUSION: Our study suggests that Adansonia digitata protects against Plasmodium berghei induced-malaria, and that administration of the extract after established infection reduced malaria progression.

Diagnostic accuracy of tru-cut biopsy of breast lumps at University College Hospital, Ibadan.

BACKGROUND: Tru-cut needle biopsies form an integral part of Triple assessment of breast cancer and include clinical assessment, mammography and core needle biopsy. No study has been done to evaluate the validity of the procedure in our environment. This study was done to evaluate the validity of core needle biopsies in our centre. METHOD: A retrospective study of patients with tru-cut needle biopsies of breast lumps and follow-up excisional biopsy or mastectomy done in the Department of Surgery, University College Hospital, Ibadan over a ten year period was done. Fifty one patients who fulfilled the inclusion criteria had their records obtained from the Department of Pathology. The diagnosis was classified into benign and malignant with the excisional biopsy or mastectomy diagnosis used as the gold standard. The sensitivity, specificity and accuracy were calculated and kappa was also done to evaluate the degree of agreement. RESULTS: A total of 51 cases were included in this study. The average age of the patients was 47 ± 13 years with a range from 19 to 81 years. Thirty of the biopsies (59%) had a definitive diagnosis of malignancy while twenty one (41%) were benign. The overall sensitivity, specificity and accuracy were 86%, 71% and 80.4% respectively. The specificity of malignant biopsies was 68% while benign was 35%. The level of agreement for malignant biopsies was higher than benign biopsies with a kappa of 0.39 for malignant diagnosis as against 0.29 for benign. CONCLUSION: Tru-cut needle biopsies have a comparable sensitivity and specificity to excisional biopsies. Diagnostic accuracy can be further enhanced with the adoption of image guided biopsies.

Primary malignant bone tumours in Ibadan, Nigeria: an update.

Bone tumours are relatively rare compared to tumours of other sites. The frequency of primary malignant bone tumours is low in our environment, as was observed in an earlier study. The aim of this study is to update the information available on the pattern of primary malignant bone tumours at the University College Hospital (UCH), Ibadan, Nigeria. The medical records of 49 patients with malignant bone tumours documented in the Cancer Registry of UCH, Ibadan between January 2001 and September 2007 were reviewed retrospectively. The results were then added to those of the previous study published in 2002. This brought the number of cases of primary malignant bone tumours to 163 from January 1977 to September 2007. Primary malignant bone tumours represented 0.53% of the 30462 cases of cancer seen in the hospital in the period studied. The male female ratio was 1.5:1. About 44% of the tumours occurred among patients less than 20 years of age. Osteogenic sarcoma was the commonest malignant bone tumour. Important changes recorded in the seven years since the last review from this centre include; a rise in the prevalence rate of primary malignant bone tumours (49 new cases in the last seven years as compared to 114 cases over 23 years), the male-female ratio of Osteogenic sarcoma showed a decline (1.5:1 as compared to 1.6:1), and there was an increase in the prevalence of primary malignant bone tumours in the 0-9 years and > 60 years age groups. The significance of these findings will need to be determined by further studies.

Central nervous system stimulants: effect on visual functions and occurrence of road traffic accidents.

OBJECTIVE: To determine the influence of the use of central nervous system (CNS) stimulants on visual functions and occurrence of road traffic accidents (RTA) amongst commercial drivers. DESIGN: A cross-sectional study in which two hundred and fifteen consecutive drivers were interviewed and their eyes examined. SETTINGS: Ife Central Local Government Area (LGA) of Osun State, Nigeria. MATERIALS AND METHODS: Out of the estimated 270 commercial drivers registered in the four major parks of the LGA, 215 consecutive drivers participated in the survey Questionnaires were administered by face-to-face interview and the drivers' eyes examined by the authors. RESULTS: The prevalence of visual impairment (visual acuity < 6/18) in the better eye without correction was 3.3%, and there was a significant association between uncorrected visual acuity impairment in the better eye and RTA (p = 0.0152). The prevalence of refractive error was 8.4%, but none of these drivers wear corrective glasses. Alcohol consumption is common (57.7%) amongst the drivers, and there was a significant association between alcohol consumption and RTA (p = 0.00124). There was also a significant association between the use of CNS stimulants (kolanut, marijuana and cigarette) and RTA (p = 0.005). CONCLUSION: It was therefore concluded that visual impairment in the better eye, alcohol consumption and the use of other CNS affecting substances contribute to the occurrence of RTA among the drivers.

Ocular manifestations of Burkitt's lymphoma: experience in Ile-Ife south western Nigeria.

BACKGROUND: Burkitt's lymphoma is the most common childhood tumour in subSaharan Africa that typically affects the jaws and abdomen. Ocular involvement with blindness has been documented in some studies. OBJECTIVE: This was to evaluate the role of Burkitt's lymphoma (BL) as a cause of blindness in Nigerian children. METHODS: Cases of BL seen in the hospital between 1986 and 2003 were studied retrospectively. Some of the patients with orbital disease at presentation underwent ultrasonographic examination of the eyes. RESULTS: Forty-three (16.5%) of the 260 patients seen presented with orbital tumours; 29 (67.4 %) of the 43 patients had full ophthalmic examination. The patients studied comprised 22 males and 7 females with a M: F ratio of 3:1, and median(age range) of 7(3-15) years. Orbital tumours occurred concurrently with jaw masses on the same side in 19(65.5 %) of 29 patients; the eye diseases were unilateral in 23 (79.3%) and bilateral in six (20.7%) of the cases. Proptosis was the ocular presentation in 27(93%) of patients and it was associated with conjunctival injection in nine, chemosis in 11 and exposure keratopathy in five. Fourteen (48.3%) patients had associated blindness; 12 (85.7%) remained blind in the affected eye(s) and one regained vision to 6/36 after chemotherapy. The patients underwent Cyclophosphamide-Oncovin-Methotrexate (COM) regimen with intrathecal therapy. Eight (27.6%) patients had concomitant CNS disease; these included cases of 6th and 7th nerve palsies, one case of intra-cerebral extension of tumour and another case of total ophthalmoplegia. CONCLUSION: Burkitt's lymphoma is an important cause of childhood blindness in Nigeria and the orbital disease ismainly extra ocular.

Indication for eye removal in Ile-Ife, Nigeria.

The indication for surgical eye removal reflects the pattern of severe ocular diseases in a given community and gives insight into the causes of uniocular blindness. It is an unfortunate end to certain ocular morbidities. In instances where the fellow eye is already blind, it then becomes even more grievous. The aim of the study is to find out the reasons for surgical eye removal in Obafemi Awolowo University Teaching Hospitals Complex (OAUTHC) Ile-Ife. Nigeria. Retrospective analytic study of records of all patients who had their eyes removed in the Ophthalmic theatre of OAUTHC Ile-Ife from January 1994 - December 2003 were reviewed without prejudice to method of such removal. A total of 94 eyes were removed during this 10 year period, out of which 92 records were available for inclusion in this study. 30.4% of the patients were below 10 years of age. The male to female ratio was 2.1:1. All cases of eye removal were uniocular. Trauma was the leading cause of eye removal (43.4%) while orbito-ocular tumour was next (30.4%). Tumour was the leading cause of eye removal in the paediatric age group (87.2%) with Retinoblastoma being the commonest indication. Six out of the 92 (6.5%) patients studied unfortunately were already blind in the second eye; in this group of individuals the reason for eye removal was preventable in 83.3%. Most of the indications for eye removal were avoidable. Eye health education is needful for the general populace and particularly for individuals with an 'only' eye.

Eye disease in Wesley Guild Hospital, Ilesa, Nigeria.

Eye disease constitutes an incapacitating condition with significant socioeconomic consequences. Regional differences occur in the pattern of presentation, which influence preventive strategies in order to achieve the goals of Vision 2020 global initiative. The purpose of the study is to determine the prevalence and causes of eye disease in Wesley Guild Hospital, Ilesa in order to provide a database for the planning of primary eye care delivery system. Medical records of new consecutive patients presenting in the eye clinic of Wesley Guild Hospital, Ilesa over a 5-year period (January 2000 - December 2004) were studied. The prevalence of eye disease was 2.3%. A total of 1717 patients had eye disorders. The mean age was 52.0 years +/- 2.4 s.d, with a female preponderance (Male: Female ratio 1:1.2). The leading diagnoses were cataract (26.0%), refractive error (18.5%), allergic conjunctivitis (12.4%) and glaucoma (10.9%). High volume cataract surgery, health education, early diagnosis and prompt management while incorporating, primary eye care within the comprehensive health care system could reduce the impact of the preventable causes of blindness.

Isolated bilateral upper lid coloboma--a case report.

BACKGROUND: Congenital upper lid colobomas may be associated with ocular and systemic anomalies. This paper reports an isolated bilateral upper lid coloboma. METHOD: A report of a case of bilateral upper lid coloboma with discussion of relevant literature. RESULTS: A 5-month old healthy baby girl presented with isolated bilateral upper lid coloboma. The coloboma was as large as two thirds of each upper lid with symblepharon. She had no other associated congenital anomalies reported by various workers. The upper lid defect in each eye was repaired in two stages. She had a flap from the lower lid using the lid switch technique and flap separation 2 weeks after the first surgery, in a combined surgery by a plastic surgeon and ophthalmologists. A good functional and cosmetic result was achieved from the treatment. The patient was discharged five days after the second surgery. CONCLUSION: This case shows that lid coloboma could be an isolated problem in a child. Early and appropriate surgical intervention is necessary for good visual and functional outcome.

Case report: intraocular cysticercosis.

A case of intravitreal cysticercosis causing left uniocular cataract and eventual left visual loss in a healthy female Nigerian is presented. The diagnosis of cysticercus celulosae was not made until the patient had left cataract extraction done. The cysticercus larva found its way into the anterior chamber and this stimulated severe ocular inflammation. The use of antihelminthic and systemic steroid caused amelioration of the patient's ocular inflammation and symptoms. The review of literature on ocular involvement and the management of cysticercosis are discussed.

Goldenhar's syndrome: case report.

A case of Goldenhar's Syndrome (oculoauriculovertebral dysplasia) in a 3-day-old Nigerian neonate with right anophthalmos and lipodermoid, left limbal dermoid, bilateral preauricular appendages and mandibular hypoplasia is presented. The lipodermoid was attached to the tarsal conjunctiva of the lower lid of the anophthalmic side. The causative factor was presumably maternal drug (traditional medicine) ingestion at three months gestation. No similar case has been reported previously. The literature on Goldenhar's Syndrome is briefly reviewed.

Invasive squamous cell carcinoma of the limbus: case report.

Limbal squamous cell carcinoma is uncommon worldwide. Its early stages of presentation may look like the commoner limbal mass, pterygium. We report a case of invasive squamous cell carcinoma which was initially diagnosed as inflamed pterygium. A high index of suspicion is required to prevent delay in the diagnosis of an invasive condition that can destroy the eye completely. Treatment modalities are reviewed.
