Figure 6: (a) Dacryoscintigraphy images reveal drainage of tracer into the lacrimal sac bilaterally; however, there is no drainage of tracer into the nasolacrimal duct bilaterally. There is a minor difference in the radioactivity administered in both eyes, causing a minor difference in intensity of tracer to start with. As scan progresses, the difference in intensity of radiotracer in the two eyes increases as more tracer is flowing out of left eye and soaked out with tissue paper, (b) dacryoscintigraphy images reveal drainage of tracer into the lacrimal sac bilaterally; however there is no drainage of tracer into the nasolacrimal duct bilaterally, (c) dacryoscintigraphy images reveal no drainage of tracer into the nasolacrimal duct bilaterally
