BACKGROUND Loeys-Dietz syndrome (LDS) is an autosomal dominant disorder of the connective tissue that has phenotypic overlap with Marfan syndrome,but the aortic root dissections can be more aggressive and ocular findings in LDS may be very different than Marfan syndrome. METHODS Review of one case of LDS with novel retinal findings. RESULTS A 30-year-old female with LDS was found to have retinal arterial macroaneurism (RAM) in the left eye. Local laser photocoatulation and intravitreal anti-VEGF was applied but exudative retinal detachment developed soon after that. Transscleral diode photocoagulation was then performed and subretinal fluid was resolved. CONCLUSION RAM is a unique finding of LDS related to a novel mutation of TGFBR1.
