AI Article Synopsis
- The study investigated the effects of deferoxamine on optic nerve changes caused by blood element breakdown in a rabbit model.
- Three groups of rabbits were used: one with induced blood clots and no treatment, one with induced clots treated with deferoxamine, and one only given deferoxamine without clots.
- Results showed that while the optic nerves in untreated rabbits displayed significant damage, those treated with deferoxamine exhibited minimal changes, indicating that this treatment is effective in preventing nerve degeneration related to blood clots.
Article Abstract
Purpose: Changes in the optic nerve due to the breakdown of blood elements and the effect of deferoxamine on these changes were evaluated.
Methods: The study group consisted of 12 rabbits. Three rabbits were used as control. In Group I, three rabbits had bilateral retrobulbar haematoma induced. In Group II, three rabbits had bilateral retrobulbar haematoma induced and were given systemic deferoxamine. In Group III, three rabbits were only given deferoxamine. At day 21, all the rabbits underwent bilateral enucleation and specimens from the orbital fat tissue were removed for light microscopic examination. The optic nerves were examined by light and electron microscopy.
Results: Light microscopic examination of the optic nerves did not reveal significant differences among the groups. Electron microscopy revealed ultrastructural changes in Group I. There were no significant pathological findings observed in Groups II or III. There was abundant iron pigment in the orbital fat tissue of Group I, but only a small amount in Group II.
Conclusion: Systemic deferoxamine treatment is effective in preventing degenerative changes in retrobulbar haema-toma.
