Fundal photograph showing severe<unk>  in the right eye. In the early stages,<unk>  may be asymptomatic or present with a headache. It can progress to enlargement of the blind spot, blurring of vision, visual obscurations (inability to see in a particular part of the visual field for a period of time). Ultimately, total loss of vision can occur.<unk>  (right) revealed by scanning laser ophthalmoscopy (top) and laser Doppler imaging (bottom). Healthy contralateral eye (left). The signs of<unk>  that are seen using an ophthalmoscope include: *venous engorgement (usually the first signs) *loss of venous pulsation *hemorrhages over and/or adjacent to the optic disc *blurring of optic margins *elevation of the optic disc *Paton's lines (radial retinal lines cascading from the optic disc) On visual field examination, the physician may elicit an enlarged blind spot; the visual acuity may remain relatively intact until<unk>  is severe or prolonged.
