Work capacity and surgical output for cataract in the national capital region of Delhi and neighbouring districts of north India.

OBJECTIVES: To ascertain time taken for cataract surgery by ophthalmologists in the National Capital Region of Delhi and neighbouring districts, to determine what work output is feasible with the available ophthalmologists. METHODS: The time-motion study was conducted during January to June 2006 in the National Capital Region of Delhi and neighbouring districts in North India. Data was collected by observing all activities from entry of a patient into the operating theatre to exit. A total of 156 cataract surgeries performed by 45 ophthalmologists in 38 hospitals were observed. A stop watch was used to record activity time, rounded off to the nearest 10 seconds. Case duration, surgical and clinical times were calculated. RESULTS: Ninety percent ophthalmologists completed surgery in 41.3 minutes. The 10th and 90th percentile for case duration time was 15.5 and 78.4 minutes respectively. Median surgical time was lowest for ophthalmologists working in the NGO sector (10 minutes), compared to the government (23.5 minutes), and private sector (17.3 minutes). Cataract surgical output can be increased in the country if operation theatre time is utilized optimally.

Epidemiological study of ocular trauma in an urban slum population in Delhi, India.

PURPOSE: To study the epidemiology and clinical profile of victims of ocular trauma in an urban slum population. MATERIALS AND METHODS: This cross-sectional study, conducted on 500 families each in three randomly selected urban slums in Delhi, collected demographic data for all members of these families, and clinical data for all those who suffered ocular trauma at any time, that required medical attention. Data was managed on SPSS 11.0. RESULTS: Of 6704 participants interviewed, 163 episodes of ocular trauma were reported by 158 participants (prevalence = 2.4%, confidence interval = 2.0 to 2.7) Mean age at trauma was 24.2 years. The association between the age of participants and the history of ocular trauma was significant ( P < 0.001), when adjusted for sex, education and occupation. Males were significantly more affected. Blunt trauma was the commonest mode of injury (41.7%). Blindness resulted in 11.4% of injured eyes ( P = 0.028). Of 6704 participants, 1567 (23.4%) were illiterate, and no association was seen between education status and trauma, when adjusted for sex and age at injury. A significant association was noted between ocular trauma and workplace (Chi-square = 43.80, P < 0.001), and between blindness and place (Chi-square = 9.98, P = 0.041) and source (Chi-square = 10.88, P = 0.028) of ocular trauma. No association was found between visual outcome and the time interval between trauma and first consultation (Chi-square = 0.50, P = 0.78), between receiving treatment and the best corrected visual acuity (Chi-square = 0.81, P = 0.81), and between the person consulted and blinding ocular trauma (Chi-square = 1.88, P = 0.170). CONCLUSION: A significant burden of ocular trauma in the community requires that its prevention and early management be a public health priority.

Need for optical and low vision services for children in schools for the blind in North India.

CONTEXT: Children admitted in blind schools need low vision assessment for improving functional vision (useful residual vision). AIM: To ascertain the need for spectacles and magnifiers as low vision devices (LVD) in children with useful residual vision, attending blind schools. SETTING AND DESIGN: Cross-sectional study conducted in 13 blind schools in Delhi, North India. MATERIALS AND METHODS: Of a total of 703 children (less than 16 years of age) examined, 133 (18.91%) with useful residual vision were refracted and analyzed. High addition plus lenses (range 5-30 diopters) were used as spectacle magnifiers for near LVD assessment. "World health organization (WHO)/ prevention of blindness (PBL) eye examination record for children with blindness and low vision", was used to collect data. SPSS (statistical package for the social science), version 10.0 was used for analysis. RESULTS: Based on the vision of 133 children at initial examination, 70.7% children were blind and 12.0% were severely visually impaired (SVI). 20.3% children improved by at least one WHO category of blindness after refraction. With best correction, 50.4% children were still blind and 13.5% were SVI. Visual acuity in the better eye after refraction in 47 children (35.3%), improved with spectacles. Children with aphakia (17), coloboma (5), refractive error (5) and microphthalmos (4) benefited from spectacles. Of 124 children with low vision but having useful residual vision, 51 (41.1%) were able to read N-10 unaided or with distance spectacles and 30 children (22.6%) improved to N-10 with spectacle magnifiers and were prescribed the same. CONCLUSION: Visually impaired children with aphakia and congenital anomalies of the eye benefit from refraction and low vision services.

Status of speciality training in ophthalmology in India.

PURPOSE: To systematically evaluate the quality of ophthalmology training in India. METHODS: Questionnaires were sent to existing medical schools and accredited training institutions. Institutions were followed up thrice to obtain responses. Data were analysed using Stata 8.0. RESULTS: Responses were received from 128 (89.5%) of the 143 institutions. Each year, 900 training slots were available across the country. Faculty: student ratios were better in accredited training institutions than in postgraduate medical schools. Fifty three (41.4%) of 128 institutions subscribed to more than 2 international journals. Fewer than 1 in 6 institutions conducted research projects. 11 (8.6%) institutions reported more than five publications in international peer-reviewed journals over three years. Only a third of the responding institutions had a wet lab. CONCLUSIONS: There is a need to improve the training facilities and optimally utilise the infrastructure available in postgraduate medical schools.

Human resources and infrastructure for eye care in India: current status.

BACKGROUND: An ophthalmic workforce and infrastructure planning survey was undertaken to provide a valid evidence base for human resource and infrastructure requirements for elimination of avoidable blindness. This is the first time that such an extensive survey has been done in India. METHODS: Pre-tested questionnaires were administered to all district-level blindness officials and ophthalmology training institutions during April 2002-March 2003. Supplementary data sources were used wherever necessary. Data analysis was done in Stata 8.0. Projections of the existing ophthalmologists and dedicated eye beds were made for the entire country using the mean, median and range for each individual state. RESULTS: The response rate was 89.3%. More than half the eye care facilities were located in the private sector. Sixty-nine per cent of the ophthalmologists were employed in the private and non-governmental sectors; 71.5% of all dedicated eye beds were managed by these two sectors. Five states (Maharashtra, Uttar Pradesh, Karnataka, Andhra Pradesh and Tamil Nadu) had half the practising ophthalmologists in India. There was a wide disparity in access to ophthalmologists and dedicated eye beds across the country. Using the median to obtain medium projections, it is estimated that there are 9478 practising ophthalmologists and 59 828 dedicated eye beds in India. CONCLUSIONS: India will be able to meet the requirements for trained ophthalmologists and dedicated eye beds to achieve the goals of Vision 2020. Some states will need special attention. Instead of an across-the-board increase in ophthalmologists and eye beds, regions which are deficient will need to be prioritized and concerted action initiated to achieve an equitable distribution of the available resources.
