Impact of a month-long training program on the clinical skills of ophthalmology residents and practitioners.

A cohort study was performed to assess the impact of an intensive, hands-on, supervised training program in ophthalmic clinical evaluation, for ophthalmology residents and private practitioners. All students underwent one-month training in comprehensive ophthalmology examination and investigations at a tertiary care center between January 2004 and January 2006. The training methodology included didactic lectures, video-demonstrations and hands-on training. The participants completed a self-assessment with a set of 23 questions designed to assess the level of confidence in various skills on the first and last day of the training. Of a total of 118 students, 67 (56.8%) were residents and 51 (43.2%) were practitioners. The mean score pre-training was 38.3 out of 92 (S.D. ±16.9), and was 70.6 out of 92 (S.D.± 10.1) post-training. The mean increase in the scores was 32.3 (P value < 0.001). We concluded that intensive, short-term training programs could improve the self-perceived level of confidence of ophthalmology residents and practitioners.

Clinico-microbiological profile and visual outcomes of post-traumatic endophthalmitis at a tertiary eye care center in South India.

PURPOSE: To analyze the clinical and microbiological characteristics of eyes with post-traumatic endophthalmitis and factors influencing the visual outcomes in these cases. METHODS: We performed a retrospective chart analysis of the clinical and microbiological data of 97 consecutive patients with post-traumatic endophthalmitis presenting to a tertiary eye care hospital in South India. RESULTS: Thirty-nine (40.2%) cases were culture-positive, gram-positive cocci (n=24/42, 57.1%) being the commonest isolates. Staphylococcus epidermidis and Pseudomonas aeuruginosa were the commonest single isolates (n=10; 23.8%). Majority of the organisms were sensitive to chloramphenicol (n=27) or ciprofloxacin (n=26). Susceptibility to vancomycin (n=3) and amikacin (n=4) was poor. Cases with negative cultures at presentation were more likely to have improvement in visual acuity compared with culture-positive cases (on multivariate analysis, OR: 3.2, 95% CI: 1.1, 9.0). CONCLUSIONS: In this series of post-traumatic endophthalmitis, a high prevalence of resistance of the culture isolates to vancomycin and amikacin was observed.

Can ocular torsion be measured using the slitlamp biomicroscope?

PURPOSE: To evaluate and compare a stereo-biomicroscopic technique of ocular torsion measurement with fundus photographic technique. METHODS: This prospective masked observational study included 72 eyes of 36 consecutive subjects with normal ocular motility. The disc-foveal angle was measured by two masked investigators using a slitlamp stereo-biomicroscopic and fundus photographic technique. RESULTS: The mean age was 13.7 years (6 - 44 years), and 15 (41.6%) were males. The average torsion using the slitlamp technique was 5.5 +/- 3.3 degrees and 6.1 +/- 4.3 degrees with fundus photographic technique. Clinical agreement between the two techniques for 5 degree and 6 degree torsion was 81% and 90% respectively. The average difference between the two techniques was 3.0 +/- 2.6 degrees . The mean inter-ocular difference was 3.3 +/- 2.7 degrees (SD, 2.77) and 5.5 +/- 4.6 degrees using the slitlamp and fundus photographic technique respectively. The Pearson correlation coefficient (r2) was 0.5. CONCLUSION: The fundus photographic technique remains the gold standard test for the measurement of ocular torsion. The slitlamp biomicroscopic method can be useful where a fundus camera is unavailable. Further studies are required to test the repeatability of these tests.

Quality of life after community-based rehabilitation for blind persons in a rural population of South India.

This study aimed to determine the impact of community-based rehabilitation on the quality of life of blind persons in a rural south Indian population. We performed a population-based survey followed by clinical examinations to identify blind persons in a rural south Indian population. Pre-and-post rehabilitation quality of life of 159 blind persons aged 15 years or above was ascertained through a questionnaire previously validated for use in this population. Post-rehabilitation quality-of-life scales showed some improvement for 151 (95.0%) subjects. The additional benefit from rehabilitation was greatest for the self-care and mobility subscales, ranging from 24.6% to 30.0% for the self care subscale and 37.6% to 44.3% for the mobility subscale with effect sizes of 21.5 and 2.38 respectively. Overall quality of life scores were not significantly different between those who did and did not receive economic rehabilitation (P = 0.1). Blind persons in this rural population benefited considerably from rehabilitation services even if economic rehabilitation is not provided. Initiatives against blindness need to consider rehabilitation of the blind as a priority.

A pilot study on awareness of diabetic retinopathy among non-medical persons in South India. The challenge for eye care programmes in the region.

This study was conducted to determine awareness and practices relating to diabetic retinopathy among non-medical persons in a south Indian population. In this population-based cross-sectional study, trained social workers conducted face-to-face interviews using a semi-structured questionnaire with 200 randomly selected paramedical personnel and 204 persons randomly selected from the community. Responses were graded on a five-point scale. Over half of respondents were not aware of risk factors for diabetic retinopathy. Only one-fifth of paramedics and one-tenth of persons from the community were aware that uncontrolled diabetes was a risk factor for retinopathy. Over 75% of respondents were not aware of either laser or surgery as an intervention for retinopathy. Although 80% of respondents from the community felt that yearly eye examinations were essential, only 43.5% had ever visited an ophthalmologist. Nearly three-fourths of paramedical personnel did not have any material related to diabetes for health education. It is evident that considerable effort is required to improve awareness of diabetic retinopathy, and to translate this improved awareness to actual utilisation of services.

Perceptions of eye diseases and eye care needs of children among parents in rural south India: the Kariapatti Pediatric Eye Evaluation Project (KEEP).

We conducted 24 focus group discussions for parents and grandparents as part of a population-based survey of ocular morbidity to determine awareness and perceptions of eye diseases in children among parents and guardians of children in a rural south Indian population. Focus group discussions were conducted separately for mothers, fathers and grandparents. They were audiotaped and subsequently transcribed to the local language and English. Content analysis of the focus group discussions was done to identify key concepts, and this yielded five broad areas of interest relating to awareness and attitudes towards: 1) eye problems in children, 2) specific eye diseases in children, 3) vision problems in children, 4) existing health practices, and 5) utilization of services. Vision impairment did not figure in the top ten eye problems cited for children. There was a predominant belief that children below 4 years should not wear spectacles. Strabismus was considered as untreatable and was seen as a sign of good luck. Differing advice provided by the medical community for the same condition was an issue. The discussions also brought out that eye doctors were approached last for eye care, after traditional healers and general physicians. The discussions raise several issues of relevance that eye care programs need to address for better community involvement with programs. This will require a far greater focus than the current curative focus adopted by most programs.

Utilization of community-based rehabilitation services for incurably blind persons in a rural population of southern India.

PURPOSE: To identify barriers in utilisation of community based rehabilitation (CBR) services for incurably blind persons in rural South India. METHODS: A community-based rehabilitation programme for incurably blind persons was initiated in Theni district of southern Tamil Nadu in south India. After door-to-door enumeration and preliminary ocular screening by trained workers at the village, identified blind persons were categorised as either curable or incurable by an ophthalmologist. Trained workers provided rehabilitation, including mobility training (OM), training to perform activities of daily living (ADL), and economic rehabilitation for the incurably blind in their respective villages. RESULTS: Of the 460,984 persons surveyed, 400 (0.09%) were certified as incurably blind including 156 (39.00%) persons blind from birth. Social rehabilitation was provided for 268 (67.00%) incurably blind persons. Economic rehabilitation was provided to 96 persons, and integrated education to 22 children. Nearly one-fifth (n=68, 17.00%) of incurably blind persons refused the services provided. The major reasons for refusal included old age and other illnesses (41.18%), and multiple handicaps (19.12%). Twenty-seven (6.75%) persons had either migrated or died, and 29 (7.25%) persons were already able to function independently. CONCLUSION: Although CBR programmes provide useful services to the incurably blind, a better understanding of barriers is required to improve service utilisation. Developing a standardised data collection format for every CBR programme can result in the creation of a national database of ophthalmic diseases.

Awareness of eye donation in an adult population of southern India. A pilot study.

PURPOSE: To determine "awareness of eye donation" and corneal transplantation in an adult population of southern India. METHODS: 507 participants chosen by systematic random sampling were interviewed using a structured questionnaire. Participants were selected among patients attending two community outreach programmes at different sites, and from patients presenting directly to the hospital. RESULTS: 257 participants (50.69%) were aware of eye donations. The major source of awareness was publicity campaigns (n=105). Only 22 (4.34%) participants were aware that eye donation had to be done within 6 hours of death. Four hundred and three (79.50%) participants were not aware of corneal transplantation. Illiteracy and rural residence were more likely predictors of ignorance. CONCLUSION: Although multiple strategies are currently followed to increase awareness of eye donations and corneal transplants, more innovative strategies have to be developed, especially to target illiterate and rural populations.
