Aim: We aimed to present the patient because being unilateral and symptomatic, who is diagnosed as familial exudative vitreoretinapatia (FEVR)

Case: In an 11-year-old male patient who presented with low vision and misalignment in the left eye, the best corrected visual acuity (BCVA) was found to be 0,9-1,0 for the right eye and 0,1 for the left eye. In the primary position, approximately 20 ° of esotropia was presented in the left eye. The globe movements were normal in all directions, and fixation was maintained with the cover test. The biomicroscopic examination was normal. On the fundus examination, the right eye was naturally observed, but on the left eye; a fibrovascular band extending from the optic disc to temporal (Figure 1) and the flattened temporal veins were observed. The differential diagnosis was premature retinopathy and FEVR, the patient didn’t have a premature birth history. The patient was directed to our retina and strabismus units. In the fundus fluorescein angiography of the retina of the patient, the right eye was naturally observed; in the left eye, fibrovascular band was extending from the optic disc to the upper temporal lobe, parallelism in the temporal veins, diffuse ischemic areas in the periphery, telangiectatic vessels and leaks were observed (Figure 2) The patient was referred for follow-up by considering the diagnosis of FEVR, and family members were called to the examination but the patient and relatives could not be reached again.

Conclusion: FEVR is a bilateral, asymptomatic, asymmetric, inherited peripheral retinal vascular disease that commonly seen in individuals without premature birth history. However, it should not be forgotten that most of the cases emerged as new mutations. In small children, deterioration of following the object, pandemic nystagmus, strabismus, leukorrhoea may be found. Visual loss usually develops in the first decade. It must be kept in mind for this reason; As seen in our patient, being unilateral of the findings supporting the diagnosis does not exclude the FEVR.
