List of changes:
1. Abstract:
a. Background/objectives
Original: We compare the feasibility and clinical utility of four handheld fundus cameras (Remidio NMFOP, Volk Pictor Plus, Volk iNview, oDocs visoScope) to a table-top camera (Zeiss VisucamNM/FA).
Change to: We compare the feasibility and clinical utility of four handheld fundus cameras/retinal imaging devices (Remidio NMFOP, Volk Pictor Plus, Volk iNview, oDocs visoScope) to a table-top camera (Zeiss VisucamNM/FA).
b. Methods
Original: Healthy participants (n = 10, mean age ± SD = 21.0 ± 0.9 years) underwent fundus photography with five fundus cameras to assess success/failure rates of image acquisition.

2. Introduction:
a. Original: In our study, we compare four handheld fundus cameras to a table-top counterpart. We assess the cameras for their feasibilities of image acquisition, image quality and gradeability, and participant experience.

3. Materials and methods:
a. Imaging modalities:
Original: Three handheld smartphone-enabled (oDocs visoScope, Remidio NMFOP, Volk iNview) and one handheld adaptor-detector based (Volk Pictor Plus) fundus camera were compared against a traditional table-top counterpart.

Original: The oDocs visoScope (Dunedin, New Zealand) is a 3D-printed fundus camera that can be attached to a smartphone.
Change to: The oDocs visoScope (Dunedin, New Zealand) is a 3D-printed adaptor which can be attached to a smartphone and together act as a retinal imaging device.
b. Participant imaging
Original: Stage 1 participants (n = 10) were recruited to assess all five fundus cameras for their success/failure rates of image acquisition in nonmydriatic and mydriatic settings.

4. Discussion
a. Original: In this study we report for the first time the comparative feasibility and utility of four handheld fundus cameras in relation to a traditional table-top fundus camera.
