A system may comprise an ophthalmoscope having a proximal end, a distal end, and a body portion with a light receptacle. The system may include a control assembly having a first side with a coupler configured to engage the proximal end of the ophthalmoscope and an extension arm configured to engage the body portion of the ophthalmoscope. The control assembly may further include a second side configured to engage a computing device having a camera and a camera flash. The control assembly may further include a sensor configured to detect light from the camera flash, a light source configured to be received in at least a portion of the light receptacle, and a circuit board configured to operatively connect the sensor and the light source. The circuit board is configured to trigger the light source in response to the camera flash.
