Background: Ocular trauma is a leading cause of monocular blindness worldwide and in developing countries, are not only more common but also more severe. Industrialization and urbanization may alter or modify prevalent aetiological factors and the presentation of ocular trauma., Objective: To determine the current pattern of eye injuries in Teaching Hospitals in Enugu State., Methods: This prospective cross-sectional descriptive study was carried out at the eye clinics and emergency units of two tertiary institutions in Enugu, Nigeria. Consecutive ocular trauma patients were enrolled over a 5-month period. On presentation, they underwent ocular examination including visual acuity (which was categorized according to the WHO classification of visual impairment and blindness}, anterior and posterior segment examinations. Injuries were grouped using the Birmingham Eye Trauma Terminology system., Results: Within the study period, 2545 new patients presented to the hospitals where the study was conducted. A total of 89 patients presented with ocular trauma, giving an incidence of 3.5%. The male to female ratio was 1.3:1 and patients aged 10 to 19 years formed the majority (24%). Domestic accidents (22%) were the most common cause of ocular injuries while blunt objects (57%) were the most common agents. Closed globe injuries constituted 76% of all injuries. Forty-three per cent of patients presented within 24 h of injury., Conclusion: Ocular trauma is still prevalent in South-eastern Nigeria and there has indeed been a change in the pattern as well as the incidence. Assault and road traffic accidents have emerged as important causes of eye injuries. In addition, there has been an improvement in the health-seeking behaviour of people living in Enugu and this may reflect positively on the uptake of recommended preventive strategies., (© 2021.

Background: Uncorrected refractive error has profound effects on children's educational and social development and spectacles are cost-effective in correcting this. However, the cosmetic appearance of spectacles may affect compliance to prescribed spectacles., Aims: This study explored spectacle design preferences of school children in Enugu State, Nigeria and any associated sociodemographic factors. A cross-sectional study among children aged 5-15 years from schools in Enugu state, Nigeria., Patients and Methods: The children independently selected from sets of spectacle frames, indicating their preferences on the basis of spectacle frame color, material, shape and size of the lens portion, design of the earpiece portions. Simple descriptive analysis was performed. Frequency tables were generated. Pearson's Chi-square test was used to test associations between categorical variables. Odds ratios were used to measure the strength of the associations where P < 0.05. Tests of significance were set at the 95% level., Results: A total of 1,167 children (45.6% male and 54.4% female) were seen. Majority of the children preferred red colored spectacle frames 467 (40%), plastic frames 723 (62%), rectangular shaped lens-pieces (55.2%), and frames with a straight earpiece 987 (84.6%). There is a strong association between gender and choice of spectacle colour (P < 0.01), gender and lens size preference (P < 0.05), and between school location and shapes of spectacle earpiece (P < 0.01)., Conclusions: Spectacle preferences exist among the study population and some demographic factors are associated with these preferences which should be considered in any childhood refractive error services., Competing Interests: None

Aims: To determine the prevalence of refractive errors and causes of visual impairment in school children in Enugu State, South-eastern Nigeria., Methods: A descriptive cross-sectional, school-based survey in children aged 5-15 years from selected primary and junior secondary schools (public and private) in both urban and rural communities of Enugu State was carried out. Ocular examinations were performed on them according to the Refractive Error in School-age Children (RESC) protocol., Results: A total of 1167 children were examined. The mean age (standard deviation) was 10.58 ± 3.0 years. Females were 653 (54.4%) of the study population. The uncorrected, presenting and best-corrected visual acuity of ≤20/40 (6/12) in the better eye of the children in this study were 3.6%. 3.5% and 0.4%. Among the children that had visual impairment, refractive error accounted for 33.3% of reduced vision while the overall prevalence of refractive error was 2.1%. Prevalence of myopia was 1.9% and hyperopia, 0.1%. The most prevalent astigmatism was ≤0.75 dioptre cylinder., Conclusion: The prevalence of refractive error in this study is low, with myopia being more common. Despite the low prevalence of refractive error, school vision screening is still important for African children as it serves as an opportunity to identify other ocular morbidities among the children., Competing Interests: None

Background: Vision screening in infants is an important part of the medical care of children as some eye abnormalities, if not treated in the first few months or years of life, can lead to irreversible vision loss. Objective: The objective of this cross-sectional, descriptive study was to identify ocular anomalies among infants attending immunization clinics in Nigeria and refer promptly and appropriately. Methodology: Infants were screened across 6 immunization clinics. Screening activities included relevant ocular history, vision assessment, external ocular examination, ocular motility, Hirschberg's test, pupil examination, and the red reflex test. Infants with abnormal findings were referred for comprehensive eye examination. Result: Of the 142 infants who underwent vision screening, 29 were referred. These referrals were either as a result of ocular abnormalities (n = 22) or presence of risk factors from history (n = 7). The prevalence of ocular abnormalities was 15.5% and neonatal conjunctivitis (38%), was the commonest ocular abnormality found. Others were bacterial conjunctivitis (14%), nasolacrimal duct obstruction (14%), strabismus (14%), capillary hemangiomas (10%), iris nevi (5%), and vernal keratoconjunctivitis (5%). Of the 7 infants referred based on history alone, 6 (85.7%) had a history of prematurity. Conclusion: Conjunctivitis, strabismus, congenital nasolacrimal duct obstruction, and capillary hemangioma are some of the prevalent disorders seen in infants at immunization clinics in Nigeria. Babies at risk of retinopathy of prematurity (preterm birth and oxygen therapy) can be identified. Immunization clinics can serve as good points of vision screening for infants in developing countries to facilitate prompt referral and treatment.

Purpose: To determine the prevalence and causes of childhood blindness in an underserved community in south-eastern Nigeria using the key informant method., Methods: This was a descriptive cross-sectional study. Key informants (KI) appointed by their respective communities received 1-day training on identification of blind children in their communities. Two weeks later, the research team visited the agreed sites within the community and examined the identified children. The World Health Organization eye examination record for blind children was used for data collection. Data entry and analysis were done with the Statistical Package for Social Sciences (SPSS) version 17.0., Results: Fifteen blind or severely visually impaired children (age range 3 months to 15 years) were identified in this community; nine of these were brought by the KIs. The prevalence of childhood blindness/severe visual impairment (BL/SVI) was 0.12 per 1000 children. By anatomical classification, operable cataract in 6 (40.0%) was the leading cause of BL/SVI in the series; followed by optic nerve lesions (atrophy/hypoplasia) in 3 (20.0%). The etiology of BL/SVI is unknown for the majority of the children (66.7%). It was presumed hereditary in four children (26.7%). Sixty percent of the blindness was judged avoidable. Only three children (20.0%) were enrolled in the Special Education Centre for the Blind., Conclusion: The prevalence of childhood BL/SVI in our study population is low but over half of the blindness is avoidable. There may be a significant backlog of operable childhood cataract in south-eastern Nigeria. The KI method is a practical method for case finding of blind children in rural communities.

There is a global rise in the prevalence of diabetes and this has led to a rise in the consequences of diabetes such as diabetic retinopathy (DR). The current study aims to determine the prevalence, awareness and determinants of DR among diabetics who attended a screening centre in Enugu, south-eastern Nigeria. A descriptive cross-sectional study was carried out among consenting diabetic patients who visited the centre. An interviewer-administered questionnaire was used to gather information on demographic details, the knowledge of the participants on effects of diabetes on the eye and previous care they had received for their eyes. Each participant underwent eye examination which included posterior segment examination with slit lamp biomicroscopy with +90DS lens after pupil dilation. A total of 80 eligible participants were examined. The prevalence of any DR among the participants was 32.1 % (95 % CI 20.6-43.5) whereas prevalence of proliferative diabetic retinopathy, PDR was 6.4 % and diabetic macular oedema, DME was 31.3 %. Age at onset of diabetes and duration of diabetes were the most determinant factors associated with DR (p = 0.039 and p = 0.000 respectively). Only ten (12.5 %) participants had undergone at least one specific eye examination to check for DR since they were diagnosed with diabetes. The major reason for not having had a prior screening is 'no one referred me for it' (31 participants, 44.3 %). DR is emerging as an important cause of blindness and severe visual impairment. Adequate screening programme and treatment protocol need to be set up for this population even in developing countries to prevent blindness.

Introduction: When presbyopia (loss of accommodation of the crystalline lens with increasing age) sets in, doing near work becomes associated with headache and eye strain. Reading and writing become a challenge. Literacy levels may be low in rural communities; nevertheless some work other than reading, like sewing, sorting stone from grain and operating mobile phones, is done with dissatisfaction. This study aims to determine the prevalence of presbyopia, the unmet presbyopia need and the presbyopia correction coverage in a rural African community., Methods: A population-based cross-sectional study was carried out in a rural population aged 35 years and greater, selected by cluster random sampling. Information was sought on biodata of the participants and they were subsequently examined. Distance visual acuity for each participant was determined. Anterior and posterior segments of the eyes were examined. Objective refraction with subjective refinement was done on all subjects with distant visual acuity less than 6/6. Near visual acuity was assessed at 40 cm with distant correction in place if required. Presbyopia was defined as inability to read N8 at 40 cm or requiring an addition of at least +1.00DS to improve near vision to at least N8. Questionnaires were administered to those identified as presbyopic on source of procurement of spectacles (if they had one) and on reasons for non-procurement of presbyopic spectacles. They were also asked to rate their difficulty with various listed near work. Data entry and analysis were done using Statistical Package for the Social Sciences v16.0 and Program for Epidemiologist v4.01 software., Results: A total of 585 subjects (participation rate 81.1%) aged 35 years and greater were interviewed and examined. The prevalence of presbyopia was 63.4% (95% confidence interval (CI) 62.6-64.2%). There was increasing prevalence with increasing age. The met presbyopia need was 17.6%, unmet need was 45.8% and presbyopic correction coverage was 27.8%. The commonest reasons for not procuring presbyopic correction were 'not a priority' (21.5%) and 'cost' (21.2%)., Conclusions: The prevalence of presbyopia in this rural African community is high. Many who need presbyopic correction do not have corrective spectacles.

Background: Many patients at high risk of contracting HIV infection may not seek voluntary counseling and testing but may have an unrelated ocular problem. The study aims to highlight the need to offer HIV voluntary counseling and testing services to ophthalmic surgery patients so that seropositive patients can be identified early and managed appropriately., Methods: The medical records of patients who underwent major eye surgery at Enugu State University of Science and Technology (ESUT) Teaching Hospital Parklane Enugu from October 2005 to September 2006 were reviewed. The patients were routinely screened for the presence of HIV infection after pretest counseling. Information was sought on patients' bio-data, type of surgery and HIV status using a protocol designed for the study., Results: A total of 133 patients had major eye surgeries during the study period; 67(50.4%) were males while 66 (49.6%) were females. The age range was 4 months to 82 years. Cataract extraction (54.9%), removal of eye (21.8%) and repair of penetrating injuries (15.1%) were the commonest operations. Four patients were HIV seropositive giving a prevalence of 3.0%., Conclusion: Patients have been identified to be HIV positive with apparently unrelated eye diseases. Routine HIV voluntary counseling and testing services is advocated for all ophthalmic surgery patients so that seropositive patients can be identified and early appropriate management commenced.

Aim: To review the management of cataract in children in a tertiary hospital in a developing country, and to highlight the challenges therein., Methods: The hospital records of children aged 15 years or less that had cataract surgery at University of Nigeria Teaching Hospital, Enugu from 2005 to 2008 were reviewed retrospectively. Information was obtained on bio-data, pre- and post-operative visual acuity (VA), biometry, and type of surgery, use of intraocular lens (IOL) and presence of co-morbidity. SPSS was used for data entry and analysis., Results: The hospital records of 21 children (26 eyes) were analyzed. There were 12 males (57.1%) and 9 females (42.9%). Pre-operative VA could not be assessed in 11 eyes (42.3%), 14 eyes (53.9%) had VA <3/60 and 1 eye (3.8%) had VA 6/60. Biometry was done in only 5 eyes (19.2%). All eyes had standard extracapsular cataract extraction without primary posterior capsulectomy; 12 eyes (46.2%) had posterior chamber intraocular lens (PC-IOL) implant while 13 eyes (50.0%) had no IOL. After 12 weeks of follow up, vision assessment was available in only 15 eyes. With best correction, VA of 6/18 or better was achieved in only 5 eyes (33.3%)., Conclusion: Inadequate facilities and inadequate follow up after surgery are some of the challenges in managing paediatric cataract in the developing countries. If these challenges are not addressed, cataract will remain a major cause of childhood blindness and low vision in Africa for many years. There should be collaboration between Paediatric Ophthalmology Centres in industrialized and developing countries to enhance skill transfer. Governmental and International Non-governmental Organizations can go a long way to facilitate this exchange.

Purpose: To study the clinical features of corneal ulcers in a tertiary hospital in Africa., Methods: This is a retrospective review of the medical records of 82 consecutive corneal ulcer patients who presented to the eye clinic of Enugu State University of Science and Technology (ESUT) Teaching Hospital Parklane, Enugu, Nigeria, in 2008. Data entry and analysis was done using SPSS version 15.0., Results: The 82 consecutive patients comprised 38 males (36.3%) and 44 females (53.7%). Fifty-five (71.4%) presented with visual acuity in the affected eye of less than 3/60. After treatment, the vision improved in 21 eyes (32.3% of the total), remained the same in 34 eyes (52.3%), and deteriorated in 4 eyes (6.2%); 6 eyes (9.2%) had to be eviscerated. Forty-three eyes (52.4%) had antecedent trauma: Only 5 patients (6.1%) presented to the hospital within 24 hours of trauma or onset of symptoms. Thirty-eight patients (47.6%) sought treatment from patent medicine dealers prior to coming to the hospital, while 16 (19.5%) admitted use of traditional eye medication., Conclusion: Trauma is a major risk factor for corneal ulcer in developing countries. Vision is often poor after treatment, making corneal ulcer a major cause of corneal blindness. Patients commonly seek help from the wrong source and only present to the hospital when these have failed.

Aim: To evaluate the visual outcome of cataract operations in a Nigerian mission hospital., Methods: The computer system cataract surgery record forms were used to collect data on the first 100 consecutive cataract surgeries performed in January and part of February 2003 at a Nigerian mission hospital, Mercy Eye Centre, Abak., Results: There were 54 males and 30 females (100 eyes). Sixteen patients had bilateral cataract. The mean age was 58.45 years (SD 13.58). Four patients were hypertensive, 3 diabetic, 2 both hypertensive and diabetic; and also 2 both hypertensive and asthmatic. Four patients had post-uveitic cataract, 3 traumatic cataract, 1 subluxated cataract not related to trauma and the rest had age-related cataract. One patient each had age-related macular degeneration and glaucoma. Only 42 patients (49 eyes) kept with their follow-up visits until 12 weeks post-operatively. Among these, pin hole or corrected visual acuity of 6/6-6/18 was achieved in 35.4%, <6/18-6/60 in 50%, and <6/60 in 14.6%. Almost half of those with poor outcome were attributed to inappropriate selection., Conclusion: The main cause of poor visual outcome in our centre is unsuspected co-morbidity. In spite of this, there is potential for good quality cataract surgery in Africa. As we pay more attention to appropriate patient selection we expect our outcome to improve. Provision of facilities for biometry would also be a great help in this direction.

Aim: To review the management of congenital glaucoma, bearing in mind the limited facilities available in developing countries., Methods: The medical records of children aged < or = 3 years with primary congenital glaucoma seen at two teaching hospitals and one private eye hospital in Enugu, Nigeria over a 5-year period were reviewed retrospectively. All the children underwent trabeculectomy without use of anti-metabolites., Results: Fifty-seven eyes of 32 patients (5 unilateral, 26 bilateral) were reviewed. Pre-operatively, 63.2% of the eyes had a corneal diameter of 12-15 mm. After surgery, the number with corneal haziness decreased from 25 (43.8%) to 15 (26.4%) (p=0.05). The mean (SD) pre-operative intra-ocular pressure (IOP) was 28.3 (7.5) mmHg and the mean post-operative IOP was 17 (5.6) mmHg (p=0.001)., Conclusions: When facilities for other treatment modalities are not available, primary trabeculectomy without the use of anti-metabolites can be employed to manage primary congenital glaucoma.

Aim: This cross sectional study was undertaken to identify the major causes of childhood severe visual impairment/blindness (SVI/BL) among students in schools for the blind in south eastern Nigeria with a view to offering treatment to those with remediable blindness., Methods: 142 students attending three schools for the blind in the study area were interviewed and examined using the World Health Organization programme for prevention of blindness (WHO/PBL) childhood blindness proforma., Results: By anatomical classification, the major causes of SVI/BL identified in the children (aged 15 years or less) were lesions of the lens (30.4%), corneal lesions (21.7%), whole globe lesions (mainly phthisis bulbi) (17.4%), and glaucoma/buphthalmos (10.9%). For the young adults (more than 15 years) these lesions accounted for 31.9%, 21.3%, 23.4%, and 8.5% of SVI/BL, respectively. For all the students, the commonest single diagnoses were cataract (23.5%) and corneal scarring (21.4%), of which 86.7% were caused by measles. By aetiological classification, childhood factors (38.6%) constituted the major cause of blindness: 37.0% in the children and 39.4% in the young adults. In 74.5% of all the students, blindness was considered avoidable., Conclusions: A high proportion of childhood blindness in schools for the blind in south eastern Nigeria is avoidable. Development of paediatric ophthalmology in Nigeria to manage childhood cataract and glaucoma is advocated.

This retrospective study reviews the clinical and histopathological features of ocular epidermoid cyst. The 30-year laboratory records of all the patients of the Igbo ethnic group, whose surgical specimens were received at a central pathology laboratory service in south-eastern Nigeria, West Africa, were reviewed. The cases with the histopathologic diagnosis of epidermoid cyst involving ocular tissues were reviewed. The data analyzed included age at diagnosis, sex, location and size of cyst, clinical description of lesion and operative diagnosis. There were eighteen patients. Ten (55.6%) of these were males and 8 (44.4%) were females. Nearly three-quarters were below the age of 20 years. The cyst was present from birth in 4 (22.2%) patients and was acquired in the rest. It occurred on the external angle of the orbit in 7 patients; on the bulbar conjunctiva in 4 patients; in the lower fornix, upper lid and medial canthus in two patients each; and on the lower lid in one patient. There was no correct diagnosis of epidermoid cyst clinically, the most common misdiagnoses being dermoid cyst (55.6%) and conjunctival cyst (16.7%). Accordingly, epidermoid cyst should be included in the differential diagnosis of cystic lesions showing ophthalmic presentation.
