The patients were followed for one and four years, respectively.Results: In both cases, the anterior and posterior segments were almost normal, although both patients had a sudden unilateral vision decrease and photopsia. Goldmann perimetry revealed enlarged blind spots and scotomas. The ERGs were reduced in both cases. SD-OCT showed that the junction of the inner and outer segment, the IS/OS line, of the photoreceptors was irregular or lost in the affected retinas. The retina in these areas was thinner due to a decrease in the thickness of both the outer nuclear layer (ONL) and inner nuclear layer (INL) in Case 2. Conclusions: The decrease in retinal thickness at the convalescent stage of AZOOR is most likely due to a shortening of not only the photoreceptors and ONL but also to a thinning of the INL in a severe case.Keywords: AZOOR, SD-OCT, IS/OS, ONL Kouichi OhtaAtsuko Sato Emi FukuiDove Medical PressarticleOphthalmologyRE1-994ENClinical Ophthalmology, Vol 2009, Iss default, Pp 423-428 (2009)
