Brief Summary
Demand in near vision correction in the community exist in the Bangladesh with a thin presence of eye- care. This study aimed to test the skill of BRAC service-providers in identifying presbyopia-cases, to ensure frequent services, meeting the community need. This was non-inferiority equivalence randomized intervention trial, done during February-June 2015, in six randomly selected sub-districts, where 2059 camp-patients were screened. BRAC Health-cadres; program organizers (PO), upgraded shasthya- shebikas (USS) and shasthya- shebikas (SS), were assigned to three different arms consisting two sub-districts through permuted-block randomization.105 eye-camps were organized with minimum 500 sample per arm. Sensitivity and specificity was calculated to understand screening performance. Screening reports were matched with the gold standard by recruiting refractionists.

Outcome Measures
Primary Outcomes (1)
Screening Accuracy
The outcome was considered as accurate and coded as "1" if the screening result agreed with the gold standard. That is, if the screening result is positive for presbyopia and the refractionist also reported it as positive or the screening result is negative and the refractionist also reported as negative.
The study duration was for 5 months, however, data was collected by organizing the eye camps over 2 weeks period
Study Arms (3)
PO (program organizers)
PO (program organizers): Employed by Brac as field level organizers. A two day presbyopia screening training were provided. A total of eight POs organized eye camps in two sub districts. POs were responsible for identifying the presbyopia patients through screening and SS assisted in organizing and mobilizing the community people for the eye camps, and glass sale (on the spot). Four camps were organized per day for five days by four POs in each sub-district. Thus a total of 40 eye camps were held in two sub districts by eight POs.
USS (Upgraded Shashthya Shebika)
USS (Upgraded Shashthya Shebika): A new caddre of community health workers of Brac. A two day presbyopia screening training were provided. In this arm, 20 USSs were assigned in two upazillas to run the two camp-day i.e. screening patients and selling glasses during the total 40 eye camps.
SS (Shashthya Shebika)
SS: Community health workers of Brac. A two day presbyopia screening training were provided. In this arm, the SS, undertook the screening of potential presbyopia cases. A total of 27 SS organized 25 eye camps in eight days in two upazilas.
Interventions
The training module and the protocol were designed in a way that a layman with limited education could be trained for screening and could sell reading glasses without any hassle, accurately and responsibly. Training module included the general anatomy of eye, common vision problems, aetiologies, determination of proper acuity of vision, sales techniques of the reading glass, marketing of products and services, and management of inventory and referrals. All the providers who participated in the current study, had no prior experience/training of screening presbyopia before the intervention. Each of the intervention arm used letter acuity chart i.e. Snellen chart as it commonly used for as a test of visual acuity
Eligibility Criteria
Community people aged 35 or more, both male or female and having difficulty with near vision were invited for screening.
You may qualify if:
- Aged 35 or more and have problem seeing close objects
You may not qualify if:
- Individuals having diagnosed eye diseases that require regular treatment and was not willing to participate in the study were excluded
