Clinical Trial Summary

The aim of the protocol is to compare the ocular outcomes after spontaneous vitreous hemorrhage treated with an early vitrectomy versus ultrasound monitoring with late vitrectomy.

The hypothesis is that an early vitrectomy could decrease the rate of retinal detachment occurring after a spontaneous vitreous hemorrhage.

Clinical Trial Description

The aim of the protocol is to compare the ocular outcomes after spontaneous vitreous hemorrhage treated with an early vitrectomy versus ultrasound monitoring with late vitrectomy.

The hypothesis is that an early vitrectomy could decrease the rate of retinal detachment occurring after a spontaneous vitreous hemorrhage.

Scientific background Spontaneous vitreous hemorrhage may occur after spontaneous posterior vitreous detachment and causes retinal break and retinal detachment in about 70% and 40% of cases respectively. The fundus examination and ultrasound have limited sensitivity to detect retinal breaks in these cases. Some retrospective studies have highlighted the benefit of an early vitrectomy for decreasing the rate of visual loss due to retinal detachment in these cases. However, to date, there is no national or international consensus regarding the management of spontaneous vitreous hemorrhage and the timing of vitrectomy.

Study design Prospective randomized clinical trial Primary objective To compare the results of an early vitrectomy versus ultrasound and fundus observation in spontaneous vitreous hemorrhage.

Secondary objectives To evaluate the rate of retinal complications in spontaneous vitreous hemorrhage treated either with early or delayed vitrectomy.

To evaluate the rate of visual loss in spontaneous vitreous hemorrhage treated either with early or delayed vitrectomy.

Primary criteria Rate of retinal detachment in eyes with spontaneous vitreous hemorrhage treated with early vitrectomy versus ultrasound observation at 6-month follow-up Secondary criteria Rate of retinal breaks and vitreo-retinal proliferation in eyes with spontaneous vitreous hemorrhage treated with early vitrectomy versus ultrasound observation at 6-month follow-up Visual acuity and rate of eyes with a loss of 5 letters or more among eyes with spontaneous vitreous hemorrhage treated with early vitrectomy versus ultrasound observation at 6-month follow-up Participants Patients with a spontaneous vitreous hemorrhage secondary to posterior vitreous detachment, with a reduced visibility of the fundus Inclusion criteria
