Trabeculectomy and manual clot evacuation in traumatic hyphaema with corneal blood staining
1Port Moresby General Hospital, Papua New Guinea.
Background:
The management of traumatic hyphaema with raised intraocular pressure and corneal blood staining is difficult. Residual blood clots after anterior chamber washout are responsible for sustained postoperative elevation of intraocular pressure, even after trabeculectomy and clot evacuation.
Methods:
Thirty-five patients with traumatic hyphaema, elevated intraocular pressure and varying degrees of corneal blood staining underwent a combined trabeculectomy with manual clot evacuation from the anterior chamber in a general hospital.
Results:
The postoperative control of intraocular pressure was found to be adequate in all patients at the end of two months. Examination of the posterior segment was made possible earlier. Although the procedure is more complex, no significant complications were encountered.
Conclusion:
In patients presenting with traumatic hyphaema, secondary glaucoma and corneal blood staining, trabeculectomy with manual extraction of the clot through a large incision appears to be a safe and reliable procedure where medical therapy fails to control the intraocular pressure.
