1. Is Self-Test Vision Corridor a useful Screening Tool in Nigeria? Presented by Anne Ebri Co-Authors: VingFai Chan Pirindha Govender Jyotikumarie Jaggernath Kovin Naidoo

2. 4 STVCs are set up in many countries: Gambia, Nigeria - 20 STVCs by a project 3Enables people detect their reduced vision 2Widely used, convenient, simple to use 1 Snellen chart painted or mounted on a wall for self - vision screening in underserved communities in West Africa. Text about what the graphs say. STEPS TO PROCESS Self -Test Vision Corridor (STVC)

3. Purpose To explore the users’ perceptions on how to improve usage. To determine the reasons for not going for further management if they failed the screening.

4. Methods Descriptive study using mixed methods. In-depth interviews were conducted using a question guide. – Demography – Factors to improve the usage of STVC – Perception of users towards STVC – Reasons for not going for follow-up management Trained personnel observed users perform self Vision testing.

9. 98.7% Close proximity to an eye facility are. Factors to improve usage + 71,564 Insert content here in the provided are. CHART 1 Insert content here in the provided are. CHART 1 99% Located at easily noticeable sites and at no cost are. 57% Considered privacy as very important

10. What do people think of STVC? What will improve the usage of the STVC? Clear Easily understood Sufficient and effective Creating more awareness about the existence of the SVTC and eyecare Putting more STVCs, to be mounted in strategic and public areas Free assistance for people found to have an eye defect What prompted them to use the SVTC? They were curious to know their vision status Because the testing is easy, accessible and free of charge They felt that it is important to do the testing Some were told to test their vision because they know they have a vision problem QUALITATIVE RESULTS PHASE PROCESS

11. 2 were hoping that the outreach would be visiting their community 8 Because they have no money (n=4) 7 Wait for hospital management to provide free service(n=4) 6 10 respondents who did not go for follow up treatment: 5 1 was diagnosed of glaucoma and 2 needed glasses. 4 2 of them went to the general hospital while 1 went to an eye center 3 3 went for follow up eye management: 2 13 of 16 people who failed their vision testing while using STVC were contacted 1 Phase 2- Follow up

12. Discussion STVCs are accessible, easy to use and free of cost. Respondents will recommend STVCs to others for its clear instructions, comparative accessibility and flexibility 3 participants who failed the test and followed up, one was diagnosed of glaucoma & 2 others received recommendation to wear spectacles 10 others did not follow up for reasons of lack of money, anticipated high cost of treatment and perceived unaffordability.

13. Discussion STVC cannot replace a proper eye examination at an eye care facility by trained eye care personnel. They can sensitize users who failed the test to seek proper attention at a nearby facility Self -Test Vision Corridors can be more effective if combined with regular health education.
