A 5-year-old Syrian female was born with Oguchi disease: a rare case report

Oguchi disease is a rare autosomal recessive disease that causes congenital stationary blindness, which is distinguished by the Mizuo-Nakamura phenomenon and caused by mutations of rhodopsin kinase gene or the arrestin gene.

Case presentation: A 5-year-old Syrian female complains of stationary night blindness, investigated by fundus photo and optical coherence photograph and diagnosed as Oguchi disease.

Discussion: Oguchi disease is an autosomal recessive retinal disorder causing stationary nyctalopia. It is characterized by Mizuo-Nakamura phenomenon, which is the alteration of fundus reflex color from golden-yellow to normal with dark adaptation. Literature reports suggest that mutations in rhodopsin kinase or arrestin genes may cause Oguchi's disease.

Conclusions: Optical coherence tomography is of great importance in Oguchi's disease. Optical coherence tomography usually shows an absence of the inner and outer segments line in the extrafoveal area during a partly dark-adaptation phase.
