The lateral rails were unscrewed from the front plate of the <jats:styled-content style="fixed-case">FP</jats:styled-content>. The front plate was detached from the <jats:styled-content style="fixed-case">FP</jats:styled-content>. The plate was fixed to an anodized aluminum plate (<jats:styled-content style="fixed-case">AAP</jats:styled-content>). The rails were screwed back onto the front plate. This system was reattached to the <jats:styled-content style="fixed-case">OP</jats:styled-content> by means of the rails. A T2‐E mount ring was screwed onto the <jats:styled-content style="fixed-case">AAP</jats:styled-content> and fixed to a digital camera body (<jats:styled-content style="fixed-case">DCB</jats:styled-content>). A flash sync extension cord was used to connect the flash cable of the Kowa to the <jats:styled-content style="fixed-case">DCB</jats:styled-content>. The images obtained with the converted Kowa were inverted horizontally and vertically using image processing software.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>The images obtained with the converted Kowa <jats:styled-content style="fixed-case">RC</jats:styled-content>‐2 were identical in format to those using the film version with a circular image surrounded by a black rectangle. The imaged ocular structures were accurately depicted, appearing upside down and reversed on the <jats:styled-content style="fixed-case">LCD</jats:styled-content> screen. The <jats:styled-content style="fixed-case">DCB</jats:styled-content> was set to manual mode and focus. The shutter speed was initially set to 1/250 s, and the <jats:styled-content style="fixed-case">ISO</jats:styled-content> was adjusted based on the ocular structure being photographed. An extra filter had to be placed over the light source to dim the light when imaging reflective fundi.</jats:p></jats:sec><jats:sec><jats:title>Conclusion</jats:title><jats:p>The converted digital version of the Kowa <jats:styled-content style="fixed-case">RC</jats:styled-content>‐2 as described provides an affordable means of obtaining high‐quality images of various ocular structures.</jats:p></jats:sec>
