각종자극(안내이물)이 초자체 및 망막에 미치는 영향

Abstract

2~3mm3 particles of iron, copper, lead, and glass were inserted into rabbits' vitreous cavity experimentally. The ocular findings were followed up by ophthalmoscopic and slit lamp examinations, and pathologic findings were observed with harnatoxylin-eosin stained specimens prepared serially for six months after insertion of the foreign bodies. 1. glass and iron particles did not result in any pathological changes on the retina after intraocular retention of foreign bodies for six months. 2. Iron particles were deposited on the ciliary epithelium after four weeks' intraocular retention. 3. Diffuse degenerative changes of the retina. destrucion of retinal cellular elements, loss of ganglion cells and gliosis were noted after four weeks' retention of lead particle. 4. Very Revere intraocular inflammatory reaction ariscd four weeks after introduction of copper particles into the vitreous cavity. 5. In no cases, pathologic changes of the retina were noted within two weeks after introduction of any foreign bodies into the rabbits' vitreous cavities.
