Barriers and enablers to low vision care services in a tertiary eye care hospital: A mixed method study

Purpose: Visual impairment is a major health concern all over the world. Globally, it has been studied that utilization of low vision care (LVC) services varies from 3% to 15%. This study describes barriers to access the LVC services and suggest enablers to improve the uptake of services in a tertiary eye care hospital. Methods: A snapshot qualitative research design with purposive sampling was adopted. Qualitative part of the study involved 13 eye care practitioners (ECPs) and 7 patients with low vision participated in one to one in-depth interviews. The interviews were audio recorded, transcribed, inductively coded, and analyzed. The barriers to access LVC services were identified and enablers to improve the uptake of services were implemented. The referral rate and utilization of LVC services were analyzed in the quantitative part. Results: Themes emerged out of qualitative part of the study were barriers, perceived benefits, and enablers to improve the uptake of LVC services. Barriers among ECPs included lack of awareness on referral criteria and available LVC. Barriers among patients were lack of knowledge and understanding about the need for services. The enablers included development of referral criteria and referral pathway to LVC services, creating awareness of LVC services to patients and ECPs, stratification levels of LVC services, and implementation of LVC counseling chamber. Referral rate improved from 25.6% to 51.2% and the utilization of services increased from 67.9% to 81.7% after implementation of the recommended enablers. Conclusion: Execution of stratified enablers increased the uptake of LVC services benefiting more number of people with low vision in this study.

Mouth - A Diagnostic Mirror of Various Diseases.

The mouth is a unique site, due to the presence of hard and soft tissues in close approximation. It serves in various purposes of speech, mastication and digestion. It is an important entry point for many pathogens in the body. Many systemic diseases manifest in the oral cavity and mouth can show early signs or the only signs of a disease process at a site elsewhere. As the mouth is an easily accessible site, the indicators it shows of various diseases should not be overlooked. A dentist thus can frequently be exposed to such conditions and play a key role in the diagnostic procedure of various systemic diseases. Appropriate knowledge of these oral manifestations is essential for early diagnosis, treatment and referral of cases.

Retinal nerve fiber layer measurements in indian eyes using the scanning laser polarimeter, GDx.

PURPOSE: To obtain retinal nerve fiber layer (RNFL) measurements in normal Indian subjects of different age groups; and to determine the differences between the right and the left eye of a subject and variations between male and female gender using the scanning laser polarimeter GDx. MATERIALS AND METHODS: Prospective cross-sectional study of 180 eyes of 94 subjects. The RNFL values were obtained with the nerve fiber analyser GDx using default quadrant positions supplied by the manufacturer. Fourteen parameters were studied. Of these 6 were average-based parameters (average thickness, superior maximum, inferior maximum, ellipse average, superior average, inferior average), 4 ratio-based parameters (symmetry, superior ratio, inferior ratio, superior/nasal), 4 "other" parameters (maximum modulation, number, ellipse modulation, superior integral). The main outcome measures were effect of age on RNFL values, comparison of males and females and the right and the left eye of a subject. RESULTS: There was a negative linear correlation with age. Three ratio-based parameters showed a statistically significant negative correlation with age. "Number" increased with age. Superior maximum, superior average, superior integral, symmetry and superior ratio were higher for the left eye. 'Number' was higher for the right eye. Superior ratio and maximum modulation were more in females than males, no difference was noted with other parameters. CONCLUSION: There was a gradual decrease of RNFL values with increasing age - the superior quadrant values were higher for the left eye than the right eye, suggesting asymmetry. No significant differences were detected between males and females.
