Fig. 2. The normal relationships of the capillary networks that can be seen with the slit lamp are a conjunctival (easily mobile) network, a superficial episcleral network in the parietal layer of Tenon's capsule, and a deep episcleral plexus closely applied to the sclera. These relationships are much more obvious in inflamed eyes (see Figs. 13, 14, and 30). (Watson PG, Hayreh S, Awdry P: Episcleritis and scleritis. Br J Ophthalmol 52(3):278– 279, 1968)
