Opinion
“Depression: let’s talk” is the theme of this year’s World Health Day. This is a timely call, as mental health is generally still under-recognised. Blindness continues to be one of the major public health problems in developing countries. As per census India - 2011, about 2.2% of the total population are disabled and of which 18.8% are visually disabled - the second highest form of disability. According to the publically-funded National Program for Control of Blindness (NPCB), cataract and refractive errors account for over 82% of visual impairment (VI) in India [1].
The research both from India and other parts of the world has revealed that VI increases with increasing age [2,3]. It is also estimated that people aged 50 years and older comprise 65% and 82% of the total visually impaired and blind, respectively [2]. VI leads to reduced quality of life (QoL) [4,5], poorer general health [6], lower social status and increased mortality [7,8]. Most studies in low-vision samples in developed and developing or transitional countries such as India have found healthy associations between best-corrected vision impairment and improvements in overall quality of life of the patients [9-12]. However, the impact of such intervention in gauging the emotional well-being of patients has been weak [10].
The WHO estimates that people with VI are three times more likely to suffer from depression and anxiety disorders [13]. There is a dearth of information on mental health issues among the visually impaired in India. However, evidence from elsewhere indicate higher levels of depressive disorders and severe anxiety symptoms amongst older as well as younger patients with VI, much higher than those found among the general population in the community [14,15]. Among visually impaired children, high prevalence of psychiatric morbidity has been reported previously [16,17]. There was only one study among children with VI in India that reported a prevalence of psychiatric co-morbidity of 8.7% [18].
The major trends of public health research in India since 2001 show an increase in the public health research output from India over the past few years. But, the quality of research in public health is not yet satisfactory enough and distributions of research areas are too inconsistent with the disease burden trends [19]. Public mental health is major health system component, which continues to be overlooked. The consequences of mental health issues for patients with VIs are far-reaching. Depression, in general, is associated with greater functional disability, morbidity, and mortality among middle-aged and older adults. Furthermore, adults with comorbid vision loss and depression are less likely to seek, be referred to, or use vision rehabilitation services; and those who do seek care tend to receive less service compared to those who are not depressed. Given these consequences, access to the services of the mental health system and the integration of mental health services into the vision rehabilitation system clearly represent high priorities in the organization of services for people with vision impairments. There is thus an urgent need to identify the force multiplier for mental health in India.
A dedicated Mental Health Policy and the recent mental health care bill 2014 are definitely right steps in this direction. Yet, there remain extensive gaps in services and widespread unmet mental health needs among people who are visually impaired. In an era where ‘inclusive development’ is being emphasized as the right path towards sustainable development, focused initiatives for the welfare of disabled persons are essential. There is an urgent need to develop and conduct further scientific research to understand the dynamics and interplay of mental health outcomes among visually-impaired children, adolescents and adults in India
