| We read with interest the article by Dr. Xuanet al,1Multimodal fundus imaging of outer retinaltubulations in choroidal osteoma patients, publishedin thefirst issue of volume 38 of the journal Retina.The article was about multimodal imaging of outerretinal tubulation in patients with choroidal osteoma,its correlations, and its significance in prognosis. Italso discussed importance of en face opticalcoherence tomography and optical coherencetomography angiography in imaging of these pa-tients in a good way. We think the article can helpus to improve our understanding of the pathophysi-ology behind the formation of outer retinal tubula-tions. This letter is for the purpose of presenting ourpoint regarding mean age of patients at diagnosis,which is mentioned in thefirst paragraph of resultsof the article:“Mean age at diagnosis was 40.2 ±12.2 years (range 22–34 years).”The mean you pro-vided is more than the range and this could not betrue. Because one of the statistically significant riskfactors for outer retinal tubulation formation in thestudy was younger age, we would appreciate if youcould kindly recheck your data and come back to uswith regards to this matter.Narges Hassanpoor, MD, MPH*Mohammad Reza Niyousha, MD†*Retina and Vitreous Service,Farabi Eye Hospital,Tehran University of Medical Sciences,Tehran, Iran†Retina and Vitreous Service,Nikookari Eye Hospital,Tabriz University of Medical Sciences,Tabriz, IranNone of the authors has anyfinancial/conflicting inter-ests to disclose.All authors’contributions: hypothesis creation andarticle writing.Reference1.
