Popis: Purpose: To report family members with familial retinal arteriolar tortuosity (FRAT) identified after sudden visual loss. Observations: A 15-year-old boy had sudden visual loss in his left eye while playing on a horizontal bar. He was referred to Nagoya City University Hospital from an eye clinic. The ophthalmologic examination showed retinal hemorrhage bilaterally. His best-corrected visual acuity (BCVA) was 20/17 in the right eye and 20/67 in the left eye. Bilateral retinal arteriolar tortuosity as well as retinal hemorrhage was seen. Since his mother with 54 years of age also had a history of retinal hemorrhage that improved spontaneously, fundus examination was performed, revealing tortuosity of the retinal arterioles. Consequently, the patient and his mother were diagnosed as FRAT. He was followed without intervention. Retinal hemorrhage gradually decreased and resolved after 3 months. The BCVA of his left eye gradually improved and reached 20/20 after 1 year. Conclusions and importance: In this case, the family history was very useful for early diagnosis. Immediate and accurate diagnosis allowed the patient to be followed without intervention and achieve subsequent resolution of retinal hemorrhage and improved vision. FRAT should be considered in cases of sub-internal limiting membrane hemorrhages in young patients even in the presence of discrete retinal arteriolar tortuosity.
