Researchers from Seoul National University Detail Findings in Hemorrhage (Hemorrhagic Complications Of Optic Nerve Head Drusen On Spectral Domain Optical Coherence Tomography)

By a News Reporter-Staff News Editor at Health & Medicine Week -- Research findings on Hemorrhage are discussed in a new report. According to news originating from Gyeonggi Do, South Korea, by NewsRx correspondents, research stated, "To describe the clinical features of hemorrhagic complications secondary to optic nerve head drusen (ONHD) using spectral domain optical coherence tomography (SD-OCT). Sixty-three consecutive patients with SD-OCT-documented ONHD who presented at Seoul National University Bundang Hospital from December 2009 to July 2012 were included."

Our news journalists obtained a quote from the research from Seoul National University, "Full ophthalmologic examinations, including fundus photographs, SD-OCT, fundus angiography, and visual field tests were analyzed in a total of 101 ONHD-positive eyes from 63 patients. Hemorrhagic ONHD complications were found in 7 eyes (7%) from a total of 101 eyes with ONHD. All of them had buried ONHD (visualized with SD-OCT) and myopia (mean spherical equivalent = -4.00 +/- 2.35 diopters). Patients with ONHD hemorrhagic complications had smaller disk diameters than patients without hemorrhagic complications (1,308 +/- 166 vs. 1,555 +/- 217 mu m, P = 0.004). Peripapillary hemorrhages were classified into the following 3 types based on SD-OCT findings: subretinal (6 eyes, 86%), retinal (5 eyes, 71%), and vitreous hemorrhage (4 eyes, 57%). Six patients (86%) complained of the recent onset of visual symptoms, but visual acuities at presentation were 20/20 in all patients. In the three patients who were followed up, most hemorrhages were absorbed without complications. Peripapillary hemorrhage can often occur in patients with buried ONHD and small disk diameters."

According to the news editors, the research concluded: "As SD-OCT can be used to visualize ONHD beneath hemorrhage, it is helpful with the differential diagnosis and follow-up evaluation."
