Fundus Camera Research Paper

Fundus Camera Reticle Setup (Mydriatic)

An often overlooked and critical step in obtaining sharp images is to set your reticle. The reticle is the adjustable viewfinder crosshairs and is unique to each operator’s eye visual acuity. To adjust, place a white piece of paper in front of the camera (alternatively, you can use the camera lens cap on), raise the illumination light to highest and while looking through the viewfinder, turn the eyepiece clockwise and counter-clockwise until crosshairs are sharpest. You are now setup.

The ICG product is a set of a powdered vial and and sterile aqueous solution.

Using a 5ml syringe and large needle (18g, pink), draw 5ml from sterile water vial.

Insert syringe into ICG powered vial making sure 5ml water contents are carefully distributed in. Take this step slow as the pressure may expel contents out from the rubber topper puncture site.

Draw the contents to mix. To fully mix, you may re-insert and re-draw the solution in a back and forth manner. Some bubbles may form with this technique which settle in a short amount of time.

Now that it’s mixed, draw 5ml ICG solution, remove preparation needle and secure butterfly infusion needle.
