“…The anatomical differences between the two vessels may indicate a difference in the velocity of blood flowing to the choroid and retina, in which choroidal blood flows in relatively high values [5]. Indeed, on angiographic inspection, the filling pattern of fluorescein angiography in the eye was successively observed at the choroidal phase, which is characterized by the first filling of the choriocapillaris and then the retinal arterial phase, which in turn is characterized by a hyperfluorescence of the retinal arteries [5]. Again, the rich blood supply to the choriocapillaris with high oxygen pressure and a high vascular permeability would be anticipated considering its role in diffusing oxygen and nutrients through the choriocapillaris to nourish the retina.…”

ABSTRACT. The microvasculature of the eye of 10 pigs was investigated using scanning electron micrographs of corrosion casts. The ciliary body, iris and bulbar conjunctiva were supplied by the iridociliary ring artery via the long posterior ciliary artery. Capillaries of the ciliary process were of large diameter (23.2-27.5 µm) with an irregular bore, forming a thoroughfare channel draining blood in the ciliary arterioles into the pars plana venous vessels. Arterioles and venules in the iris exhibited a zigzag or spiral features. The third palpebra was supplied by the anterior ciliary artery. The capillary bed of the third palpebra was dense and was formed by many rows of fine hair-pin loops. Capillaries in the bulbar conjunctiva formed a sparse network disposing approximately parallel to the epithelium and formed a well-developed venous plexus, draining into the vortex veins. Retinal arterioles formed a slender and long course to capillaries. Retinal capillaries were extremely thin (3.0-4.0 µm in diameter). The choroid was supplied by the short posterior ciliary arteries.Choroidal arterioles exhibited a thick and short course to the choriocapillaris. The choriocapillaris was flat and sinusoid-like (8.9-13.9 µm in diameter), forming a dense sheet-like network. Blood from the choroid emptied into the episcleral vein via the vortex vein. Blood from the retina was drained by the posterior ciliary veins. The functional significance of this vascular architecture was discussed.

“…Stones (dacryoliths) in the lacrimal drainage system are relatively common (Marthin et al 2005), whereas stones in the lacrimal gland are very rare and very few have been published (Naito et al 1973;Duke-Elder 1974;Baker & Bartley 1990;Baratz et al 1991;Mawn et al 1997;Zafar et al 2004). Woman are significantly more prone to developing stones in the lacrimal drainage system than men (Andreou & Rose 2002); it is therefore noteworthy that all three of our subjects were men.…”

ABSTRACT.Purpose: Stones (dacryoliths) in the lacrimal drainage system are relatively common. However, stones in the lacrimal gland itself are very rare. We present three cases of lacrimal gland stones and describe the clinical and histopathological characteristics and composition of the stones. Methods: Three patients presented with swelling in the lateral canthal region of several months' duration. Clinical examination in each case revealed a mass adjacent to the lacrimal gland. We carried out surgical excision, histological examination and Raman spectroscopy. Results: Histopathological examination of the excised material showed an eosinophilic, amorphic material organized in lamellae and localized in a ductule. The findings were consistent with a stone in the lacrimal gland in all three cases. All stones were composed of proteins of similar types. After surgery, the three patients healed without complications. Conclusions: Lacrimal gland stones represent a very rare but relevant differential diagnosis when a patient presents with unilateral persistent conjunctivitis or with a tumour in the lateral canthus. Treatment is excision under local anaesthesia.
