O. Kayikcioglu et al., DETERMINING FLUID LEVEL IN A TRANSLUCENT EYE-DROP BOTTLE - TRANSILLUMINATION BY PENLIGHT, International ophtalmology, 20(5), 1997, pp. 229-230
We describe an easy way to determine eye-drop contents in translucent
bottles. Transillumination of eye-drop bottles from behind or the bott
om by using a penlight clearly defines the fluid levels. The described
procedure may prevent disposal of eye-drop bottles containing useful
amounts of medication and prevent Ophthalmologists and Patients unexpe
ctedly coming across an empty bottle.
