Branch Retinal Artery Occlusion with Edema of Axonal Fibers Proximal to Embolus
60 years of age, male: patient showed a sudden visual field defect, the central visual acuity was 0.9, the IOP 18 mmHg. The patient was suffering from increased body mass index BMI, arterial hypertension, and arteriosclerosis of the ipsilateral carotid artery.
Acute phase:
1) Fundus image presenting an embolic occlusion in a branch retinal artery (white arrow) with a retinal edema (*).
2) OCT showing a retinal edema distal to the embolus,
3) The OCT retina thickness- map presenting an edema distally to the embolus and proximally to the embolus. The axonal fibers coming from the ischemic retinal ganglion cells showing also an edema (#). The macular area was well perfused with no edema.
Four weeks later:
4) Fundus image presenting a diminuished retinal edema (*).
5) OCT-image showing an atrophy of the whole retinal layer in the ischemic area.
6) OCT thickness- map presenting a thinning of the initially swollen retina and proximal axonal fibers.
