PURPOSE: To identify and report the perceived barriers to the provision of low vision services among ophthalmologists in India. METHODS: Seventy nine ophthalmologists responded to a structured self-administered questionnaire. Information was collected to understand the level of awareness and barriers/constraints to provision of low vision services. Significant factors associated with each barrier/constraint and perceptions on providing low vision care were investigated. RESULTS: Lack of training/knowledge [65 (82.3%)], lack of awareness [59 (74.7%)] and non-availability of low vision devices [57 (72.2%)] were perceived as the major constraints / barriers to providing low vision care. At least one significant factor was found for each of the above constraints/barriers in providing low vision care. The perception of lack of awareness as being one of the constraints/barriers was significantly higher [OR 3.97 (95% CI, 1.02 - 7.8)] among ophthalmologists from organisations providing low vision services. The perception of lack of motivation as constraintd/barrier was significantly higher [OR 3.62 (95% CI, 1.3 - 10.3)] among ophthalmologists from organisations providing low vision services and/or those involved in VISION 2020: The Right to Sight programmes [OR 3.83 (95% CI, 1.4 - 10.4)]. The likelihood of responding that low vision care is time consuming was greater for those belonging to a teaching institute [OR 7.19 (95% CI, 2.0 - 26.1)], those involved in low vision services [OR 5.45 (95% CI, 1.8 - 16.5)] and those who knew that low vision is a priority in VISION 2020 [OR 15.1, 95% CI, 1.5 -155.4]. CONCLUSION: Ophthalmologists need more education about the benefits of low vision care in order to increase their level of awareness and knowledge.

Concern about the rapidly increasing burden of low vision globally, and more specifically, in the developing world, has resulted in identification of the provision of good quality low vision care as a key element of the "Comprehensive Eye Service" model of programme development within VISION 2020: The Right to Sight programmes.- Although low vision does not fall into the category of blindness per se it has enormous social and economic consequences in terms of productivity losses and dependency.
Currently there are 45 million people worldwide who are blind and an additional 135 million with significant visual impairment or low vision. Nearly 90% of the world′s blind people live in the developing world. Many reasons have been identified for the rising tide of blindness and low vision, prominent among them being the increase of the world′s elderly population, particularly in developing countries.- It is estimated that by the year 2025 there will be about 1.2 billion older people, with almost three-quarters living in developing countries. In India, the current life expectancy at birth of 64.5 years is projected to increase to 73-77 years by the year 2020, and the current percentage of the elderly population of 8-10% is expected to increase to 20%.- A population-based study has shown that the prevalence of low vision is 1.05% in southern India. If the data are extrapolated to the estimated 1014 million population of India in the year 2000, 10.6 million people would need low vision services.
The uptake of low vision services continues to be relatively low even in more developed countries (3%-15%).- Lack of referral by ophthalmologists could be a reason for the under-utilisation of low vision services.
Concrete steps have not been taken to develop such services. Keeping this in view this study aimed to identify and report the perceived barriers to the provision of low vision services among a cross-section of a convenient sample of identified ophthalmologists.
Definition of low vision
A person with low vision is one who has impairment of visual functioning despite treatment and/or standard refractive correction, and has a visual acuity of less than 6/18 to light perception or a visual field of less than 10° from the point of fixation, but who uses or is potentially able to use, vision for the planning and/or execution of a task.
Information was collected through a self-administered structured printed questionnaire in English given to respondents prior to the workshops and fellowship programmes at our institute (October 2001 - January 2002); and also to ophthalmologists in private and government eye hospitals providing secondary eye care services in Hyderabad and Bangalore (April - May 2002). The responses were collected immediately. Details of the questionnaire are given in [Table 1]. The questionnaire was validated by administering it to the ophthalmologists (n=12) who attended our first two low vision awareness programme (February and September 2001) and suitable modifications were made to arrive at the final questionnaire.
Information was collected from a variety of convenient sources among a cross-section of easily accessible ophthalmologists, to understand the perceived barriers to the provision of low vision services. As a part of the National Programme for Control of Blindness (NPCB) supported project on assessing the contribution of the private sector to the national programme in India, 25 ophthalmologists from private and government eye hospitals in Hyderabad and Bangalore providing secondary eye care services were met by a trained interviewer and asked to complete the questionnaire. Forty-seven short and longterm ophthalmology fellows undergoing training programmes at our institute were also asked to complete the questionnaire at the time of joining the programme. Seven ophthalmologists who attended a workshop on Community Eye Health between 17 and 21 June 2002 were given the questionnaire for responses on issues related to barriers to accessing low vision services. The purpose of this meeting was to give an overview of the VISION 2020: The Right to Sight Initiative and to work out a local plan of action based on visually disabling disease/conditions prevalent in the local service area. In addition to identifying disease control priorities, the discussion focused on human resource development, infrastructure and technology, and sustainability. All the approached ophthalmologists responded to the questionnaire.
The associations among various factors and provision of low vision care were determined by univariate and multivariate analysis. Tests included a chi-square test or Fisher′s exact test to find significant factors associated with each constraint/barrier in providing low vision care depending on the number of categories in the factor. For any factor containing two categories, the Fisher′s exact test was performed and where there were more than two categories the chi-square test was done. Multivariate logistic regression analysis using the "enter" method was also performed for each constraint/barrier for providing low vision care by considering the factors found significant in the univariate analysis. If only one factor was found to be significant, then a univariate logistic regression was performed. A P-value < 0.05 was considered statistically significant. Statistical analysis was performed by using SPSS 11.0 Windows (SPSS Inc, Chicago, IL USA).
A total of 79 ophthalmologists responded to a structured questionnaire. This included information on the demographic data, primary area of activity, "VISION 2020: The Right to Sight Program" and questions to ascertain the levels of awareness and barriers/constraints to low vision services. The group included 56 (70.9%) men and 23 (29.1%) women. The socio-demographic data, the responses related to affiliation and the primary areas of eye care activity, knowledge and participation in the VISION 2020 programme are presented in [Table 2]. Responses related to the major constraints in providing low vision care are presented in [Table 3]. Lack of training / knowledge [65 (82.3%)], lack of awareness [59 (74.7%)] non-availability of low vision devices [57 (72.2%)] and lack of motivation [43 (54.4%)] were the major barriers to providing low vision care. [Table 4] shows the significant factors associated with each constraint / barrier (lack of awareness, motivation, belief that low vision services are not effective in helping patients, low vision care is not lucrative and time consuming) in providing low vision services. The perception of lack of awareness as a constraint / barrier was significantly higher [OR 3.97 (95% CI, 1.02 - 7.8)] among ophthalmologists from organisations providing low vision services. The perception of lack of motivation as being one of the constraints/barriers was significantly higher [OR 3.62 (95% CI, 1.3 - 10.3)] among ophthalmologists from organisations providing low vision services and or those involved in VISION 2020 programme [OR 3.83 (95% CI, 1.4 - 10.4)]. The likelihood of the belief that low vision services is "not lucrative" was a constraint was 6.29 (95% CI, 1.6 - 24.1) for the diploma holders compared to ophthalmologists with a postgraduate degree. The likelihood of responding that low vision services are time consuming was greater for those from the teaching institute [OR, 7.19 (95% CI, 2.0 - 26.1)], among those from organisations providing low vision services [OR, 5.45 (95% CI, 1.8 - 16.5)] and for those who knew that low vision is a priority in VISION 2020 [OR, 15.1, 95% CI, 1.5 -155.4].
In the univariate analysis, factors such as age (> 35 years, p=0.010), type of organisation (private practice, P=0.006) and those involved in the VISION 2020 programme (P=0.016) were significant for the constraint that low vision services are not effective in helping patients.
To the best of our knowledge, these are the first data on awareness of low vision among ophthalmologists in India. The data are of particular importance because it is estimated that 10.6 million people are in need of low vision services.,
Almost three-fourths of the ophthalmologists surveyed [59 (74.7%)] cited lack of awareness as a barrier in providing low vision services. We have demonstrated in an earlier study the importance of increasing awareness about low vision services among ophthalmologists and the public.  It is therefore recommended that a well designed education/awareness campaign be created to develop awareness of services for people with visual impairment, targeting eye care practitioners and the public.
A significant majority of ophthalmologists (82.3%) identified lack of training as one of the major barriers to providing low vision care. Most low vision services in India are provided at tertiary eye care centres and most of them are located in cities where trained low vision professionals are available. The availability of low vision services is related to the availability of trained human resources. The human resource base must be increased through training in low vision services, to meet the need for these services. Appropriate professionals may include ophthalmologists, mid-level eye care personnel and rehabilitation workers. Hence, it is necessary to find ways to include low vision services as part of different ophthalmic curricula. A major effort must be made at both the pre and in-service levels of medical education to sensitise the medical community to low vision services and to train them to make the appropriate referrals.
In this study, likelihood of belief that low vision services are not effective in helping patients as a constraint/barrier was more significant among those who were > 35 years of age ( P=0.010, Fisher′s exact text) compared to those who were < 35 years of age. Hence, it is clear that low-vision professionals need to provide more information to ophthalmologists in this age group about the benefits of low-vision devices and services. Improved communication and information exchange between ophthalmologists and low vision service providers has been suggested to improve practitioners′ awareness of the services and to increase the rate of referral of visually impaired patients.- In addition, low vision centres should make information about their services available to ophthalmologists who can then pass it on to their patients.
Two-thirds of the ophthalmologists who responded (72.2%) cited non-availability of low vision devices locally as a barrier to low vision services. Attempts have to be made to educate eye care professionals about the availability of low cost, good quality low vision devices in the country. Innovative methods are available to make simple optical magnifiers.,The feasibility of developing a ′low vision assessment kit′ should be pursued and field-tested.
A limitation of our study was the small sample size drawn from convenient resources. This may not represent the entire community of ophthalmologists in the country. Hence a further study with a larger sample is needed.
