摘要
BACKGROUND AND OBJECTIVE: To describe potential clinical applications of optic al coherence tomography (OCT)-in diagnosis and surgical timing in eyes with pos terior segment trauma. PATIENTS AND METHODS: In a noncomparative study, 7 consec utive patients who had open-globe or closedglobe injury and were found to have posterior abnormality that could also be detected by OCT are described. RESULTS: All patients had documented OCT abnormalities in the posterior segment. In one patient with a penetrating injury, two metal foreign bodies were located in the posterior segment, one in the vitreous compartment coupled with inflammatory rea ction and localized posterior vitreous detachment and the other embedded in the retina. In a second patient with a penetrating injury, OCT revealed the appearan ce of posterior vitreous detachment 5 days after injury. A closed-globe injury in one patient resulted in anterior optic neuropathy, manifested as disc edema a nd thickening of the circumpapillary retinal nerve fiber layer. The other patien ts had received blunt trauma and were found to have either full-thickness macul ar holes (2 patients), retinal pigment epithelium detachment at the papillomacul ar bundle site (1 patient), or macular edema (1 patient). CONCLUSIONS: OCT may s erve as an important adjunct imaging device in evaluation of injuries to the pos terior segment, qualitatively and quantitatively. It has potential in diagnosing subtle key abnormalities and in follow-up of these injuries.
