Digital eye strain in young screen users: A systematic review.

Digital eye strain (DES) or computer vision syndrome (CVS) is a phenomenon linked to ever increasing digital screen use globally, affecting a large number of individuals. Recognizing causative and alleviating factors of DES may help establish appropriate policies. We aimed to review factors that aggravate or alleviate DES symptoms in young, i.e. pre-presbyopic (< 40 years old), digital device users. We searched PubMed, Scopus, EMBASE, Cochrane, Trip Database, and grey literature up to 1st July 2021. Among a plethora of studies with heterogeneous diagnostic criteria for DES, we only included those using a validated questionnaire for the diagnosis and evaluating associated factors in young subjects. Relevant data were extracted, risk of bias assessment of the included studies and GRADE evaluation of each outcome were performed. Ten studies were included (five interventional, five observational) involving 2365 participants. Evidence coming from studies with moderate risk of bias suggested that blue-blocking filters do not appear to prevent DES (2 studies, 130 participants), while use of screens for > 4-5 h/day (2 studies, 461 participants) and poor ergonomic parameters during screen use (1 study, 200 participants) are associated with higher DES symptoms' score. GRADE evaluation for the outcomes of blue-blocking filters and duration of screen use showed low to moderate quality of evidence. It appears advisable to optimize ergonomic parameters and restrict screen use duration, for minimizing DES symptoms. Health professionals and policy makers may consider recommending such practices for digital screen users at work or leisure. There is no evidence for use of blue-blocking filters.

Blindness Secondary to Retinopathy of Prematurity in Sub-Saharan Africa.

PURPOSE: Retinopathy of Prematurity (ROP) has been suggested to be increasing in Africa. However, it was only previously documented as a cause of blindness in 8 of 48 (16.7%) sub-Saharan African countries. The purpose of this study was to better understand the magnitude and breadth of blindness from ROP in sub-Saharan Africa. METHODS: A questionnaire was sent to 455 ophthalmologists practicing in sub-Saharan Africa; the questionnaire was available in English, French and Portuguese. RESULTS: Responses were received from 132 of 455 (29%) ophthalmologists to whom the survey was sent. Eighty-three respondents were identified as ROP-involved ophthalmologists and were from 26 of 48 (54%) sub-Saharan African countries. Ophthalmologists in 23 countries reported that they examined at least one child who was blind from ROP during the last 5 years. Sixteen of these countries had not previously reported cases of blindness from ROP in the literature. The perceived occurrence of Type 1 or more severe ROP was reported to be increasing by 31 of 77 (40%) ROP-involved ophthalmologists. ROP-involved pediatric ophthalmologists and retinal surgeons reported the number of infants they examined annually with Type 1 or more severe ROP increased from a median of 1 (range: 0-15) to a median of 4 (range: 0-40) from 2015 to 2019. ROP was estimated to be the cause of blindness for 10% of all blind children examined by ROP-involved pediatric ophthalmologists and retinal surgeons during 2019. CONCLUSIONS: ROP is becoming a more important and widespread cause of childhood blindness in sub-Saharan Africa.

Case series of retinopathy of prematurity blindness in Nigeria: A wakeup call to policy makers, hospitals, ophthalmologists and paediatricians.

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.

Strengthening retinopathy of prematurity screening and treatment services in Nigeria: a case study of activities, challenges and outcomes 2017-2020.

OBJECTIVES: Retinopathy of prematurity (ROP) will become a major cause of blindness in Nigerian children unless screening and treatment services expand. This article aims to describe the collaborative activities undertaken to improve services for ROP between 2017 and 2020 as well as the outcome of these activities in Nigeria. DESIGN: Descriptive case study. SETTING: Neonatal intensive care units in Nigeria. PARTICIPANTS: Staff providing services for ROP, and 723 preterm infants screened for ROP who fulfilled screening criteria (gestational age <34 weeks or birth weight ≤2000 g, or sickness criteria). METHODS AND ANALYSIS: A WhatsApp group was initiated for Nigerian ophthalmologists and neonatologists in 2018. Members participated in a range of capacity-building, national and international collaborative activities between 2017 and 2018. A national protocol for ROP was developed for Nigeria and adopted in 2018; 1 year screening outcome data were collected and analysed. In 2019, an esurvey was used to collect service data from WhatsApp group members for 2017-2018 and to assess challenges in service provision. RESULTS: In 2017 only six of the 84 public neonatal units in Nigeria provided ROP services; this number had increased to 20 by 2018. Of the 723 babies screened in 10 units over a year, 127 (17.6%) developed any ROP; and 29 (22.8%) developed type 1 ROP. Only 13 (44.8%) babies were treated, most by intravitreal bevacizumab. The screening criteria were revised in 2020. Challenges included lack of equipment to regulate oxygen and to document and treat ROP, and lack of data systems. CONCLUSION: ROP screening coverage and quality improved after national and international collaborative efforts. To scale up and improve services, equipment for neonatal care and ROP treatment is urgently needed, as well as systems to monitor data. Ongoing advocacy is also essential.

Nigerian neonatologists perception and experience with retinopathy of prematurity.

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.

Travel burden and clinical presentation of retinoblastoma: analysis of 1024 patients from 43 African countries and 518 patients from 40 European countries.

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.

Global Retinoblastoma Presentation and Analysis by National Income Level.

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.

Evaluation of a Public Child Eye Health Tertiary Facility for Pediatric Cataract in Southern Nigeria I: Visual Acuity Outcome.

PURPOSE: A retrospective study of the outcome of congenital and developmental cataract surgery was conducted in a public child eye health tertiary facility in children <16 years of age in Southern Nigeria, as part of an evaluation. MATERIALS AND METHOD: Manual Small Incision Cataract Surgery with or without anterior vitrectomy was performed. The outcome measures were visual acuity (VA) and change (gain) in visual acuity. The age of the child at onset, duration of delay in presentation, ocular co-morbidity, non ocular co-morbidity, gender, and pre operative visual acuity were matched with postoperative visual acuity. A total of 66 children were studied for a period of six weeks following surgery. RESULTS: Forty eight (72.7%) children had bilateral congenital cataracts and 18 (27.3%) children had bilateral developmental cataracts. There were 38(57.6%) males and 28 (42.4%) females in the study. Thirty Five (53%) children had good visual outcome (normal vision range 6/6/ -6/18) post-operatively. The number of children with blindness (vision <3/60) decreased from 61 (92.4%) pre-operatively to 4 (6.1%) post-operatively. Post operative complication occurred in 6.8% of cases six week after surgery. Delayed presentation had an inverse relationship with change (gain) in visual acuity (r = - 0.342; p-value = 0.005). Pre-operative visual acuity had a positive relationship with post operative change (gain) in visual acuity (r = 0.618; p-value = 0.000). CONCLUSION: Predictors of change in visual acuity in our study were; delayed presentation and pre-operative VA. Cataract surgery in children showed clinical benefit.

Systemic Comorbidity in Children with Cataracts in Nigeria: Advocacy for Rubella Immunization.

Background. Congenital and developmental cataracts are leading causes of childhood blindness and severe visual impairment. They may be associated with systemic diseases including congenital heart diseases which are among the major causes of morbidity and mortality in childhood. The pattern of systemic comorbidities seen in children diagnosed with cataract in Calabar, Nigeria, was studied. Methods. A retrospective review was conducted on the children who had cataract surgery between 2011 and 2012. Diagnosis of the systemic condition was documented. Results. A total of 66 children were recruited for the study. Cardiac disease was seen in 26 children (39.9%), followed by delayed milestone in 16 (24.2%), intellectual disability in 14 (21.2%), deafness in 11 (16.7%), epilepsy in 4 (6.1%), and physical handicap in 3 (4.5%) of them. Clinically confirmed Congenital Rubella Syndrome was seen in 30 (45%) of the children. The pattern of CHD seen was as follows: patent ductus arteriosus in 16 (24.2%) followed by ventricular-septal defect in 5 (7.6%), atrial-septal defect in 3 (4.5%), and pulmonary stenosis in 2 (3%). Conclusion. Systemic comorbidities, especially cardiac anomalies, are common among children with cataract in Nigeria. Congenital Rubella Syndrome may be a prominent cause of childhood cataract in our environment. Routine immunization of school girls against rubella is advocated as a measure to mitigate this trend.

Michels syndrome: the first case report from India and review of literature.

A 2-year 7-month-old girl born out of a consanguineous marriage, presented at our facility with clinical features characterized by the eyelid triad of blepharophimosis, blepharoptosis and epicanthus inversus in association with hypertelorism, cleft palate and craniosynostosis. This constellation of features is suggestive of Michels syndrome. At the time of writing this report, there were only ten reported cases worldwide and to the best of our knowledge, there have been no published reports from India.

Retinopathy of prematurity in port harcourt, Nigeria.

Purpose. With many preterm babies now surviving as a result of improvement in neonatal care in Nigeria, the incidence of visual impairment/blindness as a result of retinopathy of prematurity (ROP) may rise. We describe our findings after screening starts for the first time in a 15-year-old special care baby unit so as to establish the incidence and risk factors for developing ROP. Methods. A prospective study carried out at the Special Care Baby Unit (SCBU) and Pediatric Outpatient Clinics of the University of Port Harcourt Teaching Hospital between January 1 and October 31, 2012. Fifty-three preterm babies (of 550 neonates admitted within the study period) delivered before 32 completed weeks and weighing less than 1500 g were included in the study following informed consent and the main outcome measure was the development of any stage of ROP. Results. Mean gestational age at birth was 28.98 ± 1.38 weeks. Mean birth weight was 1411 ± 128 g. Out of 550 babies admitted at SCBU, 87 of 100 preterms survived with 53 included in study. Twenty-five (47.2%) had different degrees of ROP with prevalence found to be 47.2%. Prevalence was higher (75%) in babies weighing <1300 g and those delivered before 30-week gestation (58%). Twenty-one (84%) had stage 1 no plus disease and 3 (12%) had stage 2 no plus disease. Only 1 (4%) had threshold disease in Zone 1. None had disease at stage 4 or 5 or AP-ROP. Receiving supplemental oxygen (χ (2) = 6.17; P = 0.01), presence of sepsis (χ (2) = 7.47; P = 0.006), multiple blood transfusions (χ (2) = 5.11; P = 0.02), and delivery by caesarian section (χ (2) = 4.22; P = 0.04) were significantly associated with development of ROP. There were no significant differences with gender, apneic spells, jaundice, or phototherapy. Conclusions and Relevance. All live infants with ROP were noted to regress spontaneously in this study. Though it may not be cost effective to acquire treatment facilities at the moment (the only child with treatable disease died), facilities for screening preterm infants displaying high risk features may be essential as smaller babies are saved.

Visual function of drivers and its relationship to road traffic accidents in Urban Africa.

AIM/BACKGROUND: Nigeria has one of the highest mortality rates from Road traffic accidents (RTAs). Prevention is a global priority. This study is aimed at acquiring information for effective policy formulation to improve safety on Nigerian roads. This is a cross sectional descriptive study in which consenting commercial drivers in a Nigerian motor parks were ophthalmically examined after an interview. Data analyzed with EPI-INFO version 6.0 statistical software using Chi square. P value < 0.05 was considered to be significant. RESULTS: The eyes of 400 commercial drivers were examined. Ages range from 25 to 62 years with mean of 37.8 years (SD ± 9.1) 20% did not undergo any prior driving test and only one third of those who had (n = 120, 30.9%) had a prior eye test. Up to 45.5% (n = 182) had been involved in RTAs with alcohol intoxication and driver fatigue significantly associated. Depressants such as alcohol are commonly used. Visual impairment ((p = 0.46, χ (2) = 0.3, RR = 0.62), visual field defects (p > 0.05, χ(2) = 0.78, RR = 1.25) and color vision defects (p = 0.4, χ (2) = 0.77, RR = 1.23) were not significantly associated with occurrence of RTAs. However fatigue was found to be a predisposing factor in 28% of those who had RTAs. CONCLUSION: One out of every two commercial driver has been involved in an RTA in the past in Nigeria. Fatigue while driving should be avoided. Use of depressants while driving should be penalized. Blood alcohol content (BAC) levels should routinely be measured by road safety personnel in Nigeria. Periodic eye exams should be carried out for all commercial drivers before issuing or renewing licenses to drive and treatment for any ophthalmic conditions discovered enforced.

Economic burden of glaucoma in Rivers State, Nigeria.

BACKGROUND: Primary open angle glaucoma is reported to blind 150,000 people in the Nigerian population and over 7000 in Rivers State, and requires constant follow-up. Compliance is a challenge, given that most inhabitants live below the poverty line. This study was performed to determine how Nigerian patients are affected economically by the disease. METHODS: Consecutive adult patients attending the eye clinic of the University of Port Harcourt Teaching Hospital, Rivers State, Nigeria, with a diagnosis of primary open angle glaucoma and on outpatient antiglaucoma treatment in the first 6 months of 2006, were recruited for the study. The lowest paid government worker was on USD50 (N7500.00) per month and the gross domestic product per capita was USD1150 for the period under review. RESULTS: We enrolled 120 consecutive patients of mean age 52.7 ± 10.4 years, with a male to female ratio of 2:3. The most common occupations were in the civil service (n = 56, 46.7%). All participants were on topical antiglaucoma treatment. The average cost of medical antiglaucoma medication was N6000 (USD40) per month. Computed to include indirect costs, including medical laboratory tests, transportation, and care by patient escorts, an average sum of USD105.4 (N15,810) was spent by each patient per month. Most of the patients (73.3%) were responsible for their own treatment costs. No patient accepted the cheaper option of surgery (USD275.4, N41,310). Eighty of the patients (66.7%) visited our eye clinic monthly. Direct and indirect loss to the economy was USD3,064587 per annum from those already blind. This was in addition to the USD 4.1 million being spent yearly on medical treatment by those who were visually impaired by glaucoma. CONCLUSION: Middle-income earners spent over 50% of their monthly income and low-income earners spend all their monthly earnings on treatment for glaucoma. This situation often resulted in noncompliance with treatment and hospital follow-up visits. To reduce the economic burden of glaucoma, trabeculectomy performed by experienced surgeons should be offered as first-line treatment for glaucoma in this country, rather than medical therapy.

Pattern of paediatric corneal laceration injuries in the University of Port Harcourt teaching hospital, Rivers state, Nigeria.

BACKGROUND: Corneal lacerations mostly affect younger children, commonly males, who will constitute the majority of the workforce. Clinical outcomes are reviewed and compared so that measures to reduce their occurrence and improve outcome can be proffered. METHODS: Records of all children between the ages of 1-18 yrs, who presented with penetrating eye injuries at the eye clinic of the University of Port Harcourt teaching Hospital, Rivers state, Nigeria between January 2002 and December 2009 were included. Information retrieved -patient's Bio data, presenting symptoms, presenting visual acuity (VA), source of injury, surgical intervention and outcome using VA. All data analysed with EPI Info version 6 with the aid of a statistician. RESULTS: Folders of thirty-six children (36 eyes) between the ages of 0-18 years diagnosed with corneal laceration over a period of 8 years out of 65 cases managed within that period available. Other folders reported as missing. Male female ratio 3:1, the mean age is 8.7 years (SD ± 3.67). Only one presented within 24 hours. Objects causing injury mainly missiles with stones/catapult injuries (n = 8, 22.2%). Presenting VAs in those that could be measured, ranged from 6/24 to 6/60 (n = 4, 11%) to no light perception (NLP) (n = 5, 13.9%). Associated injuries include lid laceration, cataract, vitreous haemorrhage and retinal detachment. Twenty one patients had primary corneal repair (58.3%) carried out within 7 days of presentation. Four had endophthalmitis. After 3 months follow up, VA of 6/60 and better was achieved in 11 of 18 eyes left in follow up (6/60-6/24 in 8 eyes (22.2%), 6/18 and better in 3 eyes (8.3%). CONCLUSION: Most eye injuries in children are preventable. In this study, the prognosis was better in those whose injuries were confined to a peripheral part of the cornea, with no other associated injury, who presented within 5 days and who did not have any intraocular infection at the time of presentation. The importance of health education, adult supervision of play and application of appropriate measures that is necessary for reducing the incidence and severity of trauma is emphasized.

Ophthalmic manifestations of children with Down syndrome in Port Harcourt, Nigeria.

AIM: The aim of this study was to provide a profile of oculo-visual anomalies in children with Down syndrome (DS) in Port Harcourt, Nigeria. METHODS: This comparative study assessed the visual functions of 120 children (42 DS and 78 developmentally normal children). The visual functions evaluated and the techniques used were: visual acuity (Snellen illiterate chart and Lea picture charts), refraction (static retinoscopy with cyclopegia), ocular alignment (cover test), near point of convergence (pen and rule), and external examinations and fundoscopy. RESULTS: A total of 42 children with DS (22 males, 20 females, mean age 11.43 ± 6.041 years) and control group of 78 normal children (36 females, 42 males) with mean age 6.63 ± 1.98 years were examined. Of the 42 DS children, visual acuity was less than 6/18 in eight and one of the DS and control groups, respectively. Visual acuity could not be checked conventionally in eleven participants from the DS group due to poor response. The main findings were: DS compared to control group showed refractive errors of 76.2% (half of which was from myopia) vs 14.1% (only 10% due to myopia). There was a statistically significant difference in total refractive errors between the Down syndrome group and the control group (P = 0.001, χ(2) = 18.29). Strabismus was 9.5% (75% esotropia) vs 0%, and there was a statistically significant difference (P = 0.001, χ(2) = 5.01), nystagmus was 4.8% v 0%, conjunctivitis 19.05% vs 8.97%, and keratitis 7.14% vs 0%, which was statistically significant (P = 0.05, χ(2) = 2.90). CONCLUSION: Refractive errors were prevalent in a sample of children with DS in Port Harcourt, Nigeria, whereas the prevalence of ocular diseases was low when compared to age-matched control participants. This study highlights the need for ophthalmic care in children with DS. Routine eye care such as the use of spectacles when necessary is recommended for people with DS at all ages to improve their educational and social needs as well as overall quality of life.

The Rivers State, Nigeria Eye Care Program--the first few steps towards achieving V2020.

AIM: To outline the outcome of the first eye camp of the eye care program in Rivers state which was established only in 2008 to reduce the burden of blindness in the state as revealed by the Nigerian national blindness and visual impairment survey results released in 2008 as much as possible to the lowest before the year 2020. METHODOLOGY: A descriptive analysis of the activities of the Prevention of blindness committee, Rivers established in 2008 by the Ministry of health, Rivers state, Nigeria. An analysis of the first eye camp held at the Rumuigbo health center, Rumuigbo, Port Harcourt is also presented from the records made at the time of the camp. The activities were partly sponsored by the Ministry of Health, Rivers state. Data analysis was with the help of a statistician using SPSS version 11. RESULTS: The recently released Nigerian National Survey on Blindness and Visual Impairment revealed that about 15,000 people are blind from cataract in Rivers state, Nigeria. Over a 3 day period to mark World Sight Day 2010, a total of 455 persons were screened for cataract surgery at the above venue. The mean age was 46.2 years (SD+/- 17.55) with an age range of 1 and half to 99 years. The male female ratio was 1:1. A total of 125 patients (27.5%) had cataract of which 83 were mature. Refractive error also affected 125 people (27.5%). Sixty-five people (14.3%) were suspected to have glaucoma while 13(2.9%) and 45 people (9.9%) presented with corneal opacities and allergic conjunctivitides respectively. Other conditions seen include conjunctival degenerations, inflammatory conditions, staphylomata etc. Cataract surgery was performed on 51 people (40.8% of those with all diagnosed with cataract and 61.4% of those with mature cataract. Other conditions that could not be treated on location were referred to the teaching hospital and the state hospital nearby. The postoperative cases were also referred to the same hospitals for followup. Follow up showed that majority (n=38, 74.5%) attained 6/24 to 6/60 VA range by the end of the first week with improvement to the 6/12 to 6/18 range by the end of the first month in 30 (58.8%) of the patients. CONCLUSION: It is highly desirable for periodic eye camps to take place in Rivers state as it was an eye opener that even within the township, most people who are avoidably blind are within easy reach of secondary and tertiary health facilities that can offer eye care. Satisfactory visual outcome was obtained in the majority of cases operated upon. Government is within their rights to fund subsequent programs adequately as their input is necessary for sustainability. This will help reduce the burden of the cataract blind in the state though it is not likely that V2020 will be achieved at the current rate.
