PURPOSE
To investigate postoperative visual acuities of patients who underwent vitrectomy for their dense nondiabetic vitreous hemorrhage, and in addition to assess postoperative visual results of the group who underwent early vitrectomy. METHODS: Included in the study were 52 patients (52 eyes) who had undergone vitrectomy and been followed up for longer than 4 months after surgeries. Authors investigated the underlying diseases of vitreous hemorrhage, surgical outcomes, and the rate of complications. In addition, we evaluated the results of the group who had undergone vitrectomy between 4 weeks and 6 weeks after development of hemorrhage. RESULTS: The most common cause of vitreous hemorrhage was branch retinal vein occlusion followed by macular hole, ocular trauma, central retinal vein occlusion, age related macular degeneration, Terson`s syndrome, and unknown cases. Visual acuity before operation is less than light perception to 0.3 and improved in 44 eyes (84.6%) after operation. The rate of more than 5 lines' improvement is 63.4% (33 eyes) and 51.9% (27 eyes) obtained their visual acuity of 0.5 or better. In the group which had been operated 4 to 6 weeks after the development, visual acuity improved in 100% (16 eyes). Thirteen eyes (81.2%) showed more than 5 lines' improvement of their visual acuity and 12 eyes had 0.5 or better (75.5%). The most common complication after surgeries is cataract in 5 eyes (10.8%), others were macular hole in 3 eyes (5.7%), retinal detachment in 2 eyes (3.8%), macular hole in 1 eye (6.2%). CONCLUSIONS: Pars plana vitrectomy is a good procedure to improve visual acuity for the patients who have suffered persistent visual disturbances due to non-diabetic vitreous hemorrhage. Also, early vitrectomy should be considered for early visual rehabilitation. |
