Figure 1. Experimentally induced loss of vitreous gel mass

Each eye was suspended by forceps after the posterior part of the globe (sclera, choroid, and retina) was separated from the vitreous body. The gel length was shorter in the experimental eye (left) than in the control eye (right), suggesting loss of vitreous gel mass following photothrombosis. This result is consistent with gel mass loss measurements reported in the text.
