Background: Retinal arterial macroaneurysm is a dilatation of a major artery situated typically at arteriovenous crossing or bifurcations. In our study we describe ophthalmological presentation and angiographic findings in 69 years old woman with unilateral retinal arterial macroaneurysm. Her past medical history was an end stage renal disease and renal transplantation with 6 HLA mismatches, delayed graft function due to acute interstitial and vascular rejection treated with methyloprednisolone and ATG, immunosuppression treatment conversion according to thrombotic microangiopathy in graft biopsy. Material/Methods: Observational case report. Fluorescein angiography
was performed.
Results: Ophthalmological examination revealed unilateral retinal arterial
macroaneurysm in the right eye. Acute complications: vitreous and retinal
haemorrhage and secondary retinal macular oedema with deterioration of
visual acuity were observed.
Conclusions: In this case retinal artery macroaneurysm was associated with
poorly controlled hypertension and arteriosclerosis. Such complication in
patient after renal transplant has not been yet reported before.
