retinopathy of prematurity ,screening criteria ,ap-rop ,Medicine - Abstract
Nigeria has the third largest incidence of premature birth, after India and China. Most babies that will require treatment for retinopathy of prematurity (ROP) have birth weight (BW) less than 1500g and gestational age (GA) less than 32 weeks, with initial eye examination within the first 30 days of life. This report aims to present the findings in three babies with vision threatening ROP that developed at less than 30 days of life. Routine screening for ROP was conducted for three babies. One was born GA 33 weeks, BW 1.6kg, screened for ROP on the 13th day of life, while the other two were a set of twins born at GA of 33 weeks, both BW 1.3kg, screened for ROP first on the 16th day of life. The twins were found CC –BY 4.0 to have arborizing vessels at the initial exam, which progressed to stage 3 pre-plus ROP by the 23rd day of life. The 3rd child had stage -3 plus disease at the first screening, warranting immediate LASER therapy. The screening criteria of Nigeria ROP group is BW ≤ 1500g or GA of ≤ 34 weeks, with the first eye examination within the first 30 days of life. These case reports show that larger babies can also develop sight threatening ROP within the first two weeks of life. There is a need for constant review of ROP screening criteria and timing based on locally available data

Introduction: Despite transportation liberating man and making him mobile, his increasing reliance on vehicular movement has conferred great facilities on him and his activities. The most profound culprit of all modes of transport is the road, of which traffic accidents are the most disturbing consequence of its use. Road traffic-related ocular injuries often have severe consequences and form a significant part of ophthalmic emergencies. These injuries may be missed and are therefore often underreported. Aim: To determine the causation, types, and outcomes of road traffic-related ocular injuries at the University of Ilorin Teaching Hospital, Kwara, Nigeria. Materials and Methods: This was a cross-sectional study conducted on 78 eyes of consecutive patients with road trafficrelated ocular injuries who presented at the Accident and Emergency unit of the University of Ilorin Teaching Hospital, Kwara, Algeria, between September 2012 and August 2013. The materials included the HOTV chart for vision assessment, which is a standardised, easy-to-use assessment method for both literate and illiterate individuals, a pen torch, direct ophthalmoscope, binocular indirect ophthalmoscope, slit lamp biomicroscope, Perkins tonometer, 2% fluorescein strip, 0.5% GuttTetracaine, and a handheld portable slit lamp ophthalmoscope. Patients' demographics, duration of ocular injury before presentation, Visual Acuity (VA) at presentation, type of vehicle, place of injury, classification of ocular injury, treatment, and outcome on follow-up were recorded. Results: There were 78 eyes (72 patients) with road trafficrelated ocular injuries. The age range of the subjects was 3-55 years with a mean of 31.10 years. Forty-four (61.1%) patients were young men between 20-39 years. Fifty-one (70.8%) patients were males, and 21 (29.2%) were females, with a male-to-female ratio of 2.4:1. Most of the victims were traders (22, 30.6%), and fifty-two eyes (72.2%) presented within 12 hours of ocular injury. Motorcycles were associated with ocular injury in 37 (51.4%) patients. The most common injuries were of closed globe type (contusion, lamellar laceration, superficial foreign body) in 70 patients (89.7%). Conclusion: Road traffic-related injuries have increased over the past eight years in Nigeria. Males are more commonly injured in Road Traffic Injury (RTI), and motorcycles were the most common cause of injury to road users. Three out of 36 people injured in a vehicle at the time of injury used seat belts, while none of the riders and passengers on motorcycles wore helmets. The importance of prevention, the use of safety devices, and the avoidance of risk behaviors on the road need to be emphasised. [ABSTRACT FROM AUTHOR]

- Abstract
Purpose: The International Classification of Retinopathy of Prematurity is a consensus statement that creates a standard nomenclature for classification of retinopathy of prematurity (ROP). It was initially published in 1984, expanded in 1987, and revisited in 2005. This article presents a third revision, the International Classification of Retinopathy of Prematurity, Third Edition (ICROP3), which is now required because of challenges such as: (1) concerns about subjectivity in critical elements of disease classification; (2) innovations in ophthalmic imaging; (3) novel pharmacologic therapies (e.g., antievascular endothelial growth factor agents) with unique regression and reactivation features after treatment compared with ablative therapies; and (4) recognition that patterns of ROP in some regions of the world do not fit neatly into the current classification system. Design: Review of evidence-based literature, along with expert consensus opinion. Participants: International ROP expert committee assembled in March 2019 representing 17 countries and comprising 14 pediatric ophthalmologists and 20 retinal specialists, as well as 12 women and 22 men. Methods: The committee was initially divided into 3 subcommittees-acute phase, regression or reactivation, and imaging-each of which used iterative videoconferences and an online message board to identify key challenges and approaches. Subsequently, the entire committee used iterative videoconferences, 2 in-person multiday meetings, and an online message board to develop consensus on classification. Main Outcome Measures: Consensus statement. Results: The ICROP3 retains current definitions such as zone (location of disease), stage (appearance of disease at the avascular-vascular junction), and circumferential extent of disease. Major updates in the ICROP3 include refined classification metrics (e.g., posterior zone II, notch, subcategorization of stage 5, and recognition that a continuous spectrum of vascular abnormalit

- Abstract
This cross-sectional analysis reports the retinoblastoma stage at diagnosis across the world during a single year, investigates associations between clinical variables and national income level, and investigates risk factors for advanced disease at diagnosis. Key PointsQuestionIs the income level of a country of residence associated with the clinical stage of presentation of patients with retinoblastoma? FindingsIn this cross-sectional analysis that included 4351 patients with newly diagnosed retinoblastoma, approximately half of all new retinoblastoma cases worldwide in 2017, 49.1% of patients from low-income countries had extraocular tumor at time of diagnosis compared with 1.5% of patients from high-income countries. MeaningThe clinical stage of presentation of retinoblastoma, which has a major influence on survival, significantly differs among patients from low-income and high-income countries, which may warrant intervention on national and international levels. ImportanceEarly diagnosis of retinoblastoma, the most common intraocular cancer, can save both a child's life and vision. However, anecdotal evidence suggests that many children across the world are diagnosed late. To our knowledge, the clinical presentation of retinoblastoma has never been assessed on a global scale. ObjectivesTo report the retinoblastoma stage at diagnosis in patients across the world during a single year, to investigate associations between clinical variables and national income level, and to investigate risk factors for advanced disease at diagnosis. Design, Setting, and ParticipantsA total of 278 retinoblastoma treatment centers were recruited from June 2017 through December 2018 to participate in a cross-sectional analysis of treatment-naive patients with retinoblastoma who were diagnosed in 2017. Main Outcomes and MeasuresAge at presentation, proportion of familial history of retinoblastoma, and tumor stage and metastasis. ResultsThe cohort included 4351 new patients from 153 countries; the median age at diagnosis was 30.5 (interquartile range, 18.3-45.9) months, and 1976 patients (45.4%) were female. Most patients (n=3685 [84.7%]) were from low- and middle-income countries (LMICs). Globally, the most common indication for referral was leukocoria (n=2638 [62.8%]), followed by strabismus (n=429 [10.2%]) and proptosis (n=309 [7.4%]). Patients from high-income countries (HICs) were diagnosed at a median age of 14.1 months, with 656 of 666 (98.5%) patients having intraocular retinoblastoma and 2 (0.3%) having metastasis. Patients from low-income countries were diagnosed at a median age of 30.5 months, with 256 of 521 (49.1%) having extraocular retinoblastoma and 94 of 498 (18.9%) having metastasis. Lower national income level was associated with older presentation age, higher proportion of locally advanced disease and distant metastasis, and smaller proportion of familial history of retinoblastoma. Advanced disease at diagnosis was more common in LMICs even after adjusting for age (odds ratio for low-income countries vs upper-middle-income countries and HICs, 17.92 [95% CI, 12.94-24.80], and for lower-middle-income countries vs upper-middle-income countries and HICs, 5.74 [95% CI, 4.30-7.68]). Conclusions and RelevanceThis study is estimated to have included more than half of all new retinoblastoma cases worldwide in 2017. Children from LMICs, where the main global retinoblastoma burden lies, presented at an older age with more advanced disease and demonstrated a smaller proportion of familial history of retinoblastoma, likely because many do not reach a childbearing age. Given that retinoblastoma is curable, these data are concerning and mandate intervention at national and international levels. Further studies are needed to investigate factors, other than age at presentation, that may be associated with advanced disease in LMICs., Queen Elizabeth Diamond Jubilee Trust, This work was supported by the Queen Elizabeth Diamond Jubilee Trust.

- Abstract
Background The travel distance from home to a treatment centre, which may impact the stage at diagnosis, has not been investigated for retinoblastoma, the most common childhood eye cancer. We aimed to investigate the travel burden and its impact on clinical presentation in a large sample of patients with retinoblastoma from Africa and Europe. Methods A cross-sectional analysis including 518 treatment-naïve patients with retinoblastoma residing in 40 European countries and 1024 treatment-naïve patients with retinoblastoma residing in 43 African countries. Results Capture rate was 42.2% of expected patients from Africa and 108.8%from Europe. African patients were older (95%CI -12.4 to -5.4, p<0.001), had fewer cases of familial retinoblastoma (95% CI 2.0 to 5.3, p<0.001) and presented with more advanced disease (95% CI 6.0 to 9.8, p<0.001); 43.4% and 15.4% of Africans had extraocular retinoblastoma and distant metastasis at the time of diagnosis, respectively, compared to 2.9% and 1.0% of the Europeans. To reach a retinoblastoma centre, European patients travelled 421.8 km compared to Africans who travelled 185.7 km (p<0.001). On regression analysis, lower-national income level, African residence and older age (p<0.001), but not travel distance (p=0.19), were risk factors for advanced disease. Conclusions Fewer than half the expected number of patients with retinoblastoma presented to African referral centres in 2017, suggesting poor awareness or other barriers to access. Despite the relatively shorter distance travelled by African patients, they presented with later-stage disease. Health education about retinoblastoma is needed for carers and health workers in Africa in order to increase capture rate and promote early referral. [ABSTRACT FROM AUTHOR]

Background Statement: Inadequate retinopathy of prematurity (ROP) screening coverage portends a high risk for increasing the cases of ROP blindness. This study aims to report the clinical profile of pre-term babies who developed ROP blindness, highlight the usefulness in determining screening criteria and the role of private hospitals in ROP blindness prevention. Case Series Report: Online Google form and telephone survey was conducted from May to December 2020 among paediatric ophthalmologists who provided the clinical details of ROP blind children seen between 2016 and 2020. The main outcome measured included type of the hospital of birth, gestational age, birth weight, ROP Screening and treatment, and blinding ROP Stage among children born premature. The SPSS-IBM version 26 was used for the analysis. Eighteen children blind from ROP with an equal male-to-female ratio were reported. Mean gestational age was 28.4 ± 2.2 weeks (range 26 - 34 weeks, median was 28.0 weeks). Mean birth weight was 1173.7 ± 317.9 grams (range 776 - 2100 grams, median 1125 grams). Six (33.3%) babies were born in private hospitals between 28 and 32 weeks. Sixteen (88.9%) children never had ROP screening. Fifteen (83.3%) were blind in both eyes. Six (33.3%) had Stage IVb and 12 (66.7%) Stage V. Conclusion: About 90% of the babies who became blind did not undergo ROP screening. It is crucial that all babies born at 34 weeks or earlier and have birth weight of < 1500 grams in public/private hospitals be screened for ROP to prevent this avoidable blindness in Nigeria.

- Abstract
PURPOSE: Routine eye examination in early life is not the practice in most resource-limited countries. Delay in the presentation for eye problems is typical. Community health officers are often consulted by caregivers for all health problems during routine immunization and well-baby clinics in primary healthcare for children aged 0–2 years. This study evaluated the value and limitation of interview, Bruckner red reflex test, and instrument vision screener by noneye care middle-level staff of rural and urban well-baby immunization clinics, in early detection and referral for childhood eye disorders. MATERIALS AND METHODS: This was a cross-sectional study. Middle-level community health workers (CHWs) working at well-baby/ immunization clinics were trained to perform vision screening using interview of caregivers, red reflex eye examination with ophthalmoscope, and instrument vision screener (Welch Allyn SPOT™ Vision Screener) without mydriatic drugs during routine immunization of children aged 0–2 years. IRB approval was obtained. RESULTS: Over a 6-month period in 2017, the CHWs screened 5609 children. Overall, 628 (11.2%) patients were referred to the tertiary child eye care unit. Referred cases included cataract, glaucoma, congenital nasolacrimal duct obstruction, ophthalmia neonatorum, retinoblastoma, and significant refractive errors. Referral from the interview of mothers was enhanced if specific questions to elicit visual function were asked. Bruckner red reflex test was more effective than instrument vision screener in the detection of cataract and life-threatening diseases such as retinoblastoma. Instrument vision screener was preferred by parents and better at detecting amblyopic risk factors. CONCLUSION: Preschool vision screening during routine immunization by primary healthcare workers in resource-limited settings was effective. Whenever instrument vision screener does not give any recommendation during screening, consider vision- or life-threatening pathology and refer. [ABSTRACT FROM AUTHOR]

Background: Retinopathy of Prematurity (ROP) is an avoidable condition that affects premature infants exposed to oxygen stresses at or soon after birth. In low- and middle-income countries, like Nigeria, neonatal mortality rates are high and very few infants live to develop ROP. With recent better care, ROP is now being diagnosed. Objective: This study aimed to characterize what Nigerian neonatologists understand about ROP. Methods: At a joint meeting of Nigerian pediatric ophthalmologists and neonatologists in Kebbi State held 26-29 July 2018, questionnaires collected attendees' perspective and experience with ROP including causes, risk factors and experiences. Results: Fifty-one neonatologists out of 71 returned a completed questionnaire (response rate: 71.8%). The male:female ratio was 1:1.8, and approximately 40% were aged 41-50 years (n=20, 39.22%). Only 3 (6.39%) had experience managing infants below 500g that survived. A majority managed babies with a mean weight of 913g ± 300.37 and age of 27.87 weeks ±2.37. Most had no access to oxygen monitors (n=39,78%). Most had 10 babies to one monitor and used average settings of 90-95%. One third had seen a case of ROP (n=15,29.41%). Only 5.88% (n=3) were unaware of uncontrolled oxygen use as a risk factor. Only 4 (8.89%) had a functional screening team. None were aware of local screening guidelines. Conclusions: Regular educational programs, collaborative clinical presentations and webinars about ROP targeted at the neonatologists and parents, including establishment of screening programs across country will likely help reduce the burden of ROP blindness in Nigeria.

- Abstract
Retinoblastoma is the commonest childhood primary malignant intraocular neoplasm that is often characterized by spontaneous regression. They display photoreceptor differentiation. This study provides the clinical presentations and histological profiles of retinoblastoma in Ilorin, Kwara – State, in the North Central geo-political zone of Nigeria. A retrospective study of clinically and histologically verified retinoblastoma at the University of Ilorin Teaching Hospital, Ilorin, Kwara – State, Nigeria from January 1989 to December 2000 was undertaken. The clinical and histological features were analyzed using the patient's case folder and surgical pathology records. There were 20 patients, 9 males and 11 females (M:F ratio 1: 1.2), age range from 5 1/2 months to 6 years with 23 eyeball tumours histologically confirmed retinoblastoma during the study period. Proptosis with chemosis was the most common clinical presentation (84.6%). Bilaterality was 15% in this study. Enucleation and Exenteration combined with chemotherapy were offered to 15 (75%) and 5 (25%) patients respectively. A poorly differentiated type with extensive areas of tumour necrosis was the commonest histological pattern. Thirteen (65%) of the patients died before completing the course of chemotherapy.

Purpose: To characterize the demographic and psychosocial problems of a group of blind people as a way of attracting more attention to and providing data that can improve the psychosocial care of the visually impaired. Materials and Method: A cross-sectional descriptive study of a population of totally blind people in Ilorin, Nigeria using a self-report questionnaire (SRQ). The questionnaire was verbally administered by the study personnel in the local language. Simple frequency tables were obtained and the Chi-square test was performed to determine significant differences between variables. P-value <0.05 was considered statistically significant. Results: Sixty one blind patients consented to participate. Most participants were engaged in street begging for their livelihood. Most subjects desired a job change, signifying dissatisfaction with the present occupation. Up to 80% of the cohort was married and had spouses who were also blind in at least one eye. Approximately two-thirds had five or more children and majority lived with family members who were responsible for taking care of their personal hygiene, cooking and mobility. The majority developed blindness in childhood and 16% had a family history of blindness and 77% had never used conventional eye care, with corneal disease being the most frequent cause of blindness. Many feared that their children may also become blind. Thirty-one (51%) scored =5 on SRQ and were classified as probable cases of psychological disorder. Conclusion: Blindness in a majority of cases that started in childhood was probably preventable. Inaccessibility to or failure of the formal rehabilitation and social welfare systems may have caused this psychosocial dilemma. The high level of social and family interaction provides opportunity for organized preventive ophthalmology, community health care services and psychosocial care. [ABSTRACT FROM AUTHOR]

- Abstract
Prcis: Twenty-four-hour intraocular pressure measurement (Phasing) among glaucoma suspects showed higher intraocular pressure (IOP), greater fluctuation, and more varying peak times occurring mostly outside clinic hours, between 12 midnight and 8 am in 68.9% of them., Purpose: To characterise 24-hour variation in IOP, in glaucoma suspects and normal individuals in an African population., Materials and Methods: A cross-sectional analytical study was carried out between March and October 2019 at the University of Ilorin Teaching Hospital. A total of 204 study participants, comprising 102 primary open angle glaucoma (POAG) suspects and 102 age and sex-matched controls with healthy eyes were recruited. Participants had a comprehensive ophthalmic examination. Measurements of IOP were taken every 2 hours during a 24-hour period using an iCare tonometer., Results: The mean age was 43.64±14.02 SD and 43.02±13.55 SD ( P =1.000) for POAG suspects and controls, respectively. The mean peak IOP was significantly higher in POAG suspects (21.87± 4.65 mm Hg) compared with controls (17.17± 2.32 mm Hg) ( P <0.001). Whereas, the mean trough IOP reading was not significantly different between the 2 groups. In both groups of participants, the peak and trough IOP in the majority were recorded outside of clinic hours. The majority (68.9%) of POAG suspects had a peak IOP between midnight and 8 am, whereas the control group peaked mostly at 4 pm (16.7%) and 4 am (41.7%). Twenty-four-hour IOP variation was 6 mm Hg or less in 73.6% of control eyes, while in the POAG suspects, 83.3% of eyes had variation greater than 6 mm Hg., Conclusions: Compared with age and sex-matched healthy controls, glaucoma suspects of African descent showed significantly higher mean IOP and IOP variation, with most peak IOP detected outside of clinic hours., Competing Interests: Disclosure: The authors declare no conflict of interest., (Copyright © 2023 Wolters Kluwer Health, Inc.

Bruckner red reflex test was more effective than instrument vision screener in the detection of cataract and life-threatening diseases such as retinoblastoma. Instrument vision screener was preferred by parents and better at detecting amblyopic risk factors., Conclusion: Preschool vision screening during routine immunization by primary healthcare workers in resource-limited settings was effective. Whenever instrument vision screener does not give any recommendation during screening, consider vision- or life-threatening pathology and refer., Competing Interests: The authors declare that there are no conflicts of interests of this paper., (Copyright: © 2020 Taiwan J Ophthalmol.)

- Abstract
Importance: Early diagnosis of retinoblastoma, the most common intraocular cancer, can save both a child's life and vision. However, anecdotal evidence suggests that many children across the world are diagnosed late. To our knowledge, the clinical presentation of retinoblastoma has never been assessed on a global scale., Objectives: To report the retinoblastoma stage at diagnosis in patients across the world during a single year, to investigate associations between clinical variables and national income level, and to investigate risk factors for advanced disease at diagnosis., Design, Setting, and Participants: A total of 278 retinoblastoma treatment centers were recruited from June 2017 through December 2018 to participate in a cross-sectional analysis of treatment-naive patients with retinoblastoma who were diagnosed in 2017., Main Outcomes and Measures: Age at presentation, proportion of familial history of retinoblastoma, and tumor stage and metastasis., Results: The cohort included 4351 new patients from 153 countries; the median age at diagnosis was 30.5 (interquartile range, 18.3-45.9) months, and 1976 patients (45.4%) were female. Most patients (n = 3685 [84.7%]) were from low- and middle-income countries (LMICs). Globally, the most common indication for referral was leukocoria (n = 2638 [62.8%]), followed by strabismus (n = 429 [10.2%]) and proptosis (n = 309 [7.4%]). Patients from high-income countries (HICs) were diagnosed at a median age of 14.1 months, with 656 of 666 (98.5%) patients having intraocular retinoblastoma and 2 (0.3%) having metastasis. Patients from low-income countries were diagnosed at a median age of 30.5 months, with 256 of 521 (49.1%) having extraocular retinoblastoma and 94 of 498 (18.9%) having metastasis. Lower national income level was associated with older presentation age, higher proportion of locally advanced disease and distant metastasis, and smaller proportion of familial history of retinoblastoma. Advanced disease at diagnosis was more common in LMICs even after adjusting for age (odds ratio for low-income countries vs upper-middle-income countries and HICs, 17.92 [95% CI, 12.94-24.80], and for lower-middle-income countries vs upper-middle-income countries and HICs, 5.74 [95% CI, 4.30-7.68])., Conclusions and Relevance: This study is estimated to have included more than half of all new retinoblastoma cases worldwide in 2017. Children from LMICs, where the main global retinoblastoma burden lies, presented at an older age with more advanced disease and demonstrated a smaller proportion of familial history of retinoblastoma, likely because many do not reach a childbearing age. Given that retinoblastoma is curable, these data are concerning and mandate intervention at national and international levels. Further studies are needed to investigate factors, other than age at presentation, that may be associated with advanced disease in LMICs.

- Abstract
Retinopathy of prematurity (ROP) is one of the leading causes of preventable blindness in children worldwide. Middle-income nations are currently experiencing epidemic levels of ROP, because greater access to neonatal intensive care units has improved survival rates of premature infants, but without sophisticated oxygen regulation. The epidemiology, screening infrastructure, treatment options, and challenges that these countries face are often tied to unique local socioeconomic, cultural, geopolitical, and medical factors. We present an overview and narratives of the current state of ROP in eight countries that are or soon will be experiencing ROP epidemics-India, Kenya, Mexico, Nigeria, Phillipines, Romania, Thailand, and Venezuela-with a view to fostering both an understanding of the differences in the ROP landscape in various settings and an interest in the further development of ROP screening and treatment services tailored to local requirements., (Copyright ©2019.

- Abstract
Retinoblastoma (RB) is the most common ocular cancer, and it typically presents before the age of 5 years in over 90% of cases. In high resource countries, RB patients tend to survive and retain their sight. This is not the case in low-resource countries because of late presentation and delayed intervention arising mostly from sociocultural and socioeconomic challenges. RB has no gender or racial predilection; the incidence is estimated as 1:16,000-1:18,000 live-births or 11/1 million children under 5 years. Most of the world's RB cases are found in Asia and Africa while most RB treatment centres are in America and Europe. RB is easy to detect by caregivers as a glowing white 'cat eye reflex' at night or when captured on camera. Health workers at primary care level can detect RB in early life if red reflex test and/or squint (Hirschberg) tests are deployed as part of wellness checks done especially during routine immunisation and well-baby clinics in the first 24 months of life. In most cases of RB, biopsies for histological confirmation are not required for diagnosis and treatment decisions to be made. Clinical information, ophthalmic evaluation and imaging modalities are typically used. There have been significant changes in the management of RB using various treatment modalities such as enucleation with orbital implant, use of chemotherapy delivered through intravenous, intravitreal, periocular and intra-arterial routes and targeted treatment with laser, cryotherapy and brachytherapy. Algorithm for management and development of the national RB program within the context of a low-resource country is presented from review of data extracted from Mendeley library, PubMed library, Google Scholar and One Network; full-text articles were mostly retrieved through the American Academy of Ophthalmology., Competing Interests: None

- Abstract
Purpose: The study compared ocular biometry values using applanation and immersion techniques to determine the most applicable method for our tertiary training centre where personnel with different levels of experience and expertise in biometry take measurements used in calculation of required intraocular lens before cataract surgery., Methods: The study was a prospective cross-sectional comparative study of different techniques of ocular biometry from diagnostic equipment (biometry probe 10 MHz Sonomed(®) A-scan (PACSCAN 300A, USA). Measurement variables were obtained among children and adults undergoing cataract surgery. Scleral (Prager) shell was used for the immersion technique followed by the contact technique by the same examiner., Results: The biometry values of 92 eyes of 92 adult were taken. Their ages ranged from 18 to 95 years with a mean of 64.7 (SD ± 12.9) years. There were 55 (59.8%) males and 37 (40.2%) females, with a male to female ratio of 1.5:1. Average axial length (22.0-24.4 mm) eyes were the most common eyes measured in 75 (81.5%) of the cases. The means of the axial lengths biometry values with immersion and contact technique were 23.66(±1.36) and 23.46 mm (±1.46); the axial length differences was 0.2 ± 0.26 mm (range 0.0-0.94 mm) and statistically significant (95% CI of the Difference 0.15 to 0.26, p = 0.000). The Standard deviation SD (mm) of Individual Eye Axial Length showed a mean of 0.03 ± 0.04 (0.0-0.3) mm for immersion and for contact technique 0.14 ± 0.12(0.0-0.6)mm., Conclusion: There was a significant difference in ocular biometry measurement with the contact and immersion ultrasound techniques. The immersion technique had better repeatability, thus it is ideal in a training hospital setting in a typical in sub-Saharan Africa who have limited resources to employ a dedicated person to do biometry; and where the different operators of A-scan machines have different levels of experience and expertise.
