Imaging the ora serrata with the 3Nethra Neo camera - Importance in screening and treatment in retinopathy of prematurity

Dear Editor, Goyal et al. describe the use of a condensing lenses with a smartphone attached to a portable, noncontact device to capture retinal images of eyes with retinopathy of prematurity (ROP)[1] Using the iPhone 5S (Apple, Cupertino, USA) and either 20D, 28D, or 40D lenses they were able to achieve 46°, 53°, or 90° of field of view, respectively. [...]Goyal et al. mention that the “Optos ultrawide camera, RetCam Shuttle, and the 3Nethra Neo” are “unable to image out to the ora serrata.” Whereas the former two cameras are well known as wide-field retinal cameras and have a published track record of imaging the retinal periphery including the ora serrata, we present images from the Neo device which depicts the ora serrata in a mature retina [Figure 1]a and Type 2 ROP [Figure 1]b and during laser treatment [Figure 2]a and [Figure 2]b. The KIDROP program uses the depiction of the ora serrata (on both the RetCam shuttle and the Neo) in both eyes to demonstrate a “fully vascularized” or mature retina before the infant is discharged from the screening protocol.
