Siepser Vitreous Floater Demonstrator

Product Number: 15153

Purchase Gulden’s Siepser Vitreous Floater Demonstrator.  Globe is filled with mineral oil to mimic the vitreous when shaken.  Use a penlight to demonstrate the shadow effect.


This model allows the doctor or technician to quickly demonstrate how “floaters” are caused and how they may affect the patients’ vision.  The model includes the Weiss Ring.

To explain the concept of “shadowing” and the consequential effect on the patient’s vision, shine your penlight through the model’s lens and create shadows on the macula.

It is made of plastic, measures three (3) inches in diameter, and is mounted on a white, sturdy, opaque, plastic base.
