Abstract

In order to see whether the binocular patching with cycloplegia improves the prognosis in the treatmet of traumatic hyphema, we studied prospectively 77 patients with nonperforating traumatic hyphema who were admitted and treated at the Chonnam University Hospital between January 1994 and July 1995. We analyzed the clearance time of blood clot in the anterior chamber, the incidence of rebleeding and the final visual acuity. The patients were divided into four groups : group I, of 17 patients treated by monocular patching ; group II, of 19 patients treated by monocular patching with cycloplegia ; group III, of 20 patients treated by absolute bed rest with binocular patching ; group IV, of 21 patients treated by absolute bed rest with binocular patching and cycloplegia. The average clearance time of blood clot was 7.4 days in group I, 7.4 days in group II, 6.9 days in group III and 7.5 days in group IV. The incidence of rebleeding was 5.8% (n=1) in group I, 10.5% (n=2) in group II, 0% (n=0) in group III, 14.3% (n=3) in group IV. The final visual acuity of 0.6 or better was achieved in 10 patients (58.8%) of group I, 13 patients (68.4%) of group II, 13 patients (65.0%) of group III, 14 patients (66.7%) of group IV. In the treatment of traumatic hyphema, binocular and monocular groups as well as cycloplegic and non-cycloplegic groups showed no significant difference from each other in the clearance time of blood clot, incidence of rebleeding and the final visual acuity.
