Background: Eye conditions in children can have negative consequences on visual functioning and quality of life. There is a lack of data on the magnitude of children with eye conditions who need services for effective planning of school eye health programmes. To address this, the School Eye Health Rapid Assessment (SEHRA) tool is being developed to collect data to support school eye health programme planning.Methods: The module, 'the magnitude and nature of local needs in school children' is the first of six modules in the SEHRA tool. The module outlines a school-based cluster survey designed to determine the magnitude of eye health needs in children. This paper outlines the survey sampling strategy, and sample size calculations.Results: The requirements for the SEHRA survey indicate that in regions where a larger sample size is required, or where fewer schools are recruited to the survey, confidence in the accuracy of the data will be lower.Conclusions: The SEHRA survey module 'the magnitude and nature of local needs in school children' can be applied in any context. In certain circumstances, the confidence in the survey data will be reduced. [ABSTRACT FROM AUTHOR]

PURPOSE: Cataract surgical rate (CSR) (cataract surgeries performed per million population) is an eye health indicator that helps assess the state of eye care services. A survey in 2002 revealed a CSR of 2254. The current survey aimed to establish a new and sustainable development goal compliant baseline for the volume of cataract surgery performed by different service providers in Pakistan at district, provincial, and national levels. METHODS: The survey was commissioned by the National Committee for Eye Health under the Ministry of National Health Services, Regulations and Coordination. The methodology used for the survey included identification and mapping of all service providers by district and category and data collection from all districts in the country. RESULTS: There were more cataract surgeries performed in women than men with a male-to-female ratio of 0.95. About 98.9% of all cataract surgeries were performed with intraocular lenses, while 63.9% were performed by phacoemulsification. About 17.7% of cataract surgical services were provided in the government sector (including Forces), while nongovernmental organizations and the private sector contributed to 82.3%. Pakistan achieved a national CSR of 5307 which is almost double the CSR determined in 2002. CONCLUSION: In order to achieve a CSR of 7500+ by 2030, there is a need for at least 1,840,000 cataract surgeries to be performed annually. If there is no change in the current annual cataract surgical output, the CSR will drop to 4628 by 2030. [ABSTRACT FROM AUTHOR]

Abstract Background Pakistan is highly vulnerable to climate change due to its geographic location, high dependence on agriculture and water resources, low adaptive capacity of its people, and weak system of emergency preparedness. This paper is the first ever attempt to rank the agro-ecological zones in Pakistan according to their vulnerability to climate change and to identify the potential health repercussions of each manifestation of climate change in the context of Pakistan. Methods A climate change vulnerability index is constructed as an un-weighted average of three sub-indices measuring (a) the ecological exposure of each region to climate change, (b) sensitivity of the population to climate change and (c) the adaptive capacity of the population inhabiting a particular region. The regions are ranked according to the value of this index and its components. Since health is one of the most important dimensions of human wellbeing, this paper also identifies the potential health repercussions of each manifestations of climate change and links it with the key manifestations of climate change in the context of Pakistan. Results The results indicate that Balochistan is the most vulnerable region with high sensitivity and low adaptive capacity followed by low-intensity Punjab (mostly consisting of South Punjab) and Cotton/Wheat Sindh. The health risks that each of these regions face depend upon the type of threat that they face from climate change. Greater incidence of flooding, which may occur due to climate variability, poses the risk of diarrhoea and gastroenteritis; skin and eye Infections; acute respiratory infections; and malaria. Exposure to drought poses the potential health risks in the form of food insecurity and malnutrition; anaemia; night blindness; and scurvy. Increases in temperature pose health risks of heat stroke; malaria; dengue; respiratory diseases; and cardiovascular diseases. Conclusion The study concludes that geographical zones that are more exposed to climate change in ecological and geographic terms- such as Balochistan, Low-Intensity Punjab, and Cotton-Wheat Sindh -also happen to be the most deprived regions in Pakistan in terms of socio-economic indicators, suggesting that the government needs to direct its efforts to the socio-economic uplift of these lagging regions to reduce their vulnerability to the adverse effects of climate change.

Blindness in childhood is a priority of Vision 2020, a global initiative for the elimination of avoidable blindness (www.v2020.org), even though the worldwide total of 45 million blind people includes [...]

Childhood blindness and visual impairment (CBVI) are major disabilities that compromise the normal development of children. Health resources and practices to prevent CBVI are suboptimal in most countries in the Eastern Mediterranean Region (EMR). We reviewed the magnitude and the etiologies of childhood visual disabilities based on the estimates using socioeconomic proxy indicators such as gross domestic product (GDP) per capita and <5-year mortality rates. The result of these findings will facilitate novel concepts in addressing and developing services to effectively reduce CBVI in this region. The current study determined the rates of bilateral blindness (defined as Best corrected visual acuity(BCVA)) less than 3/60 in the better eye or a visual field of 10° surrounding central fixation) and functional low vision (FLV) (visual impairment for which no treatment or refractive correction can improve the vision up to >6/18 in a better eye) in children <15 years old. We used the 2011 population projections, <5-year mortality rates and GDP per capita of 23 countries (collectively grouped as EMR). Based on the GDP, we divided the countries into three groups; high, middle- and low-income nations. By applying the bilateral blindness and FLV rates to high, middle- and low-income countries from the global literature to the population of children <15 years, we estimated that there could be 238,500 children with bilateral blindness (rate 1.2/1,000) in the region. In addition, there could be approximately 417,725 children with FLV (rate of 2.1/1,000) in the region. The causes of visual disability in the three groups are also discussed based on the available data. As our estimates are based on hospital and blind school studies in the past, they could have serious limitations for projecting the present magnitude and causes of visual disabilities in children of EMR. An effective approach to eye health care and screening for children within primary health care and with the available resources are discussed. The objectives, strategies, and operating procedures for child eye-care are presented. Variables impacting proper screening are discussed. To reach the targets, we recommend urgent implementation of new approaches to low vision and rehabilitation of children. [ABSTRACT FROM AUTHOR]

Purpose: Since the Declaration of Alma Ata, universal coverage has been at the heart of international health. The purpose of this study was to review the evidence on factors and interventions which are effective in promoting coverage and access to cataract and other health services, focusing on developing countries. Methods: A thorough literature search for systematic reviews was conducted. Information resources searched were Medline, The Cochrane Library and the Health System Evidence database. Medline was searched from January 1950 to June 2010. The Cochrane Library search consisted of identifying all systematic reviews produced by the Cochrane Eyes and Vision Group and the Cochrane Effective Practice and Organisation of Care. These reviews were assessed for potential inclusion in the review. The Health Systems Evidence database hosted by MacMaster University was searched to identify overviews of systematic reviews. Results: No reviews met the inclusion criteria for cataract surgery. The literature search on other health sectors identified 23 systematic reviews providing robust evidence on the main factors facilitating universal coverage. The main enabling factors influencing access to services in developing countries were peer education, the deployment of staff to rural areas, task shifting, integration of services, supervision of health staff, eliminating user fees and scaling up of health insurance schemes. Conclusion: There are significant research gaps in eye care. There is a pressing need for further high quality primary research on health systems-related factors to understand how the delivery of eye care services and health systems' capacities are interrelated.

State and nonstate health programs in developing countries are often influenced by priorities that are defined in the Millennium Development Goals (MDGs). In the wake of recessionary pressures, policy makers in the health sector are often seen to divert significant budgets to some specific health programs and make only token allocations for other health problems that are important but do not fall under the traditional MDG box of health priorities. This paper illustrates the economic argument for investment in one such program: The eye health program and employs a country case study of Pakistan to demonstrate that there are significant economic gains that are being foregone by not addressing the needs of the blind in poverty reduction strategies. By applying appropriate growth and discounting factors and using the average wage rate, the paper estimates the total productivity gains that are realizable over a period of 10 years if the blind population in Pakistan is rehabilitated and their carers released to participate in the mainstream economic activity. Our findings indicate that significant productivity gains accumulated over 10 years, range from 61 billion (US$ 709 million) to 421 billion (US$ 4.9 billion) depending upon whether the entire blind population or only those affected by a specific cause are rehabilitated. The per annum productivity gains of rehabilitating the entire blind population represents 0.74% of the current gross domestic product of Pakistan, which is higher than the total public spending on health. In order to reap these benefits, the subsequent absorption of the rehabilitated blind and their carers into mainstream economic activity is as important as their effective rehabilitation.

Background: Refractive errors are the commonest cause of vision impairment in Pakistan, but control efforts are hampered by a paucity of data for planning. To address these information gaps, a study design was developed to look at both the demand and supply sides. The objectives were to review the available human resources, determine the methods of provision of refractive services, determine the level and gaps in infrastructure available for refractive services, estimate the number of refractions provided and identify the training needs for these services. Methods: Stakeholder consultation between the National Steering Committee for Prevention of Blindness and the Pakistan Association of Opticians, to agree on objectives and method, desk research study, two population-based studies and situation analysis of refractive services provided by public and private sectors. Results: The prevalence of visually disabling refractive errors (visual acuity less than 6/12) is about 3.7% and rises with each decade after 30 years, mostly due to presbyopia. Over 6 million refractions are done annually by 868 ophthalmologists in the private sector, 235 hospitals, 1352 of the 2049 opticians and less than 200 optometrists. More than 2 million pairs of spectacles are dispensed per year. The training needs identified by opticians include optometry, refraction and contact lenses (65%), fitting of lenses and "edging" (57%), powering of lenses (45%), low vision (38%) and artificial eyes (35%). Conclusions: One of the strategies to control refractive errors is training and widespread deployment of optometrists/refractionists in public and private sectors. The current training programs cannot address the need; new programs must be set up, and existing programs must increase their intake. New programs are required for training dispensing opticians.

purpose To determine the prevalence of non-vision-impairing ocular conditions (NVIC) and estimate the number of primary eye care treatments per 1000 population per month. methods A cross-sectional study in a random sample of 1670 people was done to determine the load of NVIC in a village in Chakwal district. results The prevalence of NVIC was 30.6% (306 per 1000 population). NVIC with the exclusion of presbyopia accounted for 14.6%. The main NVIC were allergic conjunctivitis (3.7%), bacterial conjunctivitis (3.5%), pterygium/pinguicula (2.6%) and acute/chronic dacryocystitis (1%). The average Complaint Frequency (CF) per month/1000 population was 55, excluding complaints of near vision and watery eyes. conclusions The foundation of a comprehensive district eye care strategy in the light of VISION 2020 - the Right to Sight - remains an effective primary eye care service whose elements are treatment of NVIC, detection and referral of cataracts and refractive errors, and promotion of eye health.

Purpose: This study aimed to assess the capacity for ophthalmic education in the 8 South Asian Association for Regional Cooperation (SAARC) countries and to determine the need and future projections of eye health professionals in the region., Design: This was a retrospective study and comprised desk review and Web-based questionnaire., Methods: Developed in the Asia Pacific region, the Capacity Assessment Tool for SAARC Eye Care Education, a Web-based survey mechanism derived from a 12-point framework, was used to collect data on the number of ophthalmologists and other eye care personnel, training institutions, and capacity for training in each SAARC country., Results: There are an estimated 17,568 practicing ophthalmologists and 4086 ophthalmic subspecialists in the SAARC region. The population per ophthalmologist is approximately 92,270. Allied eye health professionals constitute an important element of the eye health workforce and have a population per allied eye health professional of approximately 99,852; the ophthalmologist to doctor (physician) ratio is 1:61. There are more than 510 centers providing ophthalmology training and more than 32 centers providing subspecialty training; ophthalmic subspecialty training varies from a 3-month observership to a 12-month hands-on training., Conclusions: In the SAARC region, the challenge is to sustain and increase the eye health workforce to meet the needs of a growing and aging population. The demographic transitions, improved child survival and life expectancy rates, and emerging noncommunicable disease trends require training of ophthalmic subspecialists and supporting eye care teams to meet the service delivery demands of changing eye health paradigms.
