To investigate the efficacy of early vitrectomy for dense vitreous hemorrhage without a history of diabetic retinopathy.
Patients with dense vitreous hemorrhage from unknown origin were retrospectively reviewed. Dense vitreous hemorrhage was defined as follows: 1) a measured visual acuity (VA) of 20/60 or worse, 2) requirement a B-scan ultrasonography. Eyes with a history of diabetic retinopathy were excluded. Eyes with suggestive retinal detachment on B-scan were also excluded. The outcome measures were the cause of the vitreous hemorrhage and final VA. We also investigated the differences on final VA between early (<2weeks) and delayed (>2weeks) surgical intervention of pars plana vitrectomy.
One hundred and two eyes of 102 patients were enrolled. The most common causes of dense vitreous hemorrhage were branched or central retinal vein occlusion (RVO) (34 eyes, 33.3%), and retinal tear or retinal detachment (RD) (32 eyes, 31.7%). LogMAR VA improved significantly from 1.87±0.62 to 0.53±0.65 after pars plana vitrectomy (p<0.001). Final VA of eyes treated within 2 weeks had a significant better compared with that of eyes treated later than 2weeks after the onset of symptoms (p=0.027). The most common complication was retinal detachment (6 eyes, 5.9%).
RVO and RD were the most common causes of the dense vitreous hemorrhage. The surgical intervention within 2weeks after the onset of symptoms may have benefits to prevent the disease progression.
