Abstract
We appreciate the interest shown in our article by Doctors Gandorfer, Haritoglou, and Kampik and thank them for their comments. We find their study of vitreoschisis in diabetic eyes with diffuse diabetic macular edema of interest. In our study based on optical coherence tomography (OCT), we were not able to observe any signs of vitreoschisis in any of the eyes studied. In fact, the OCT appearance of the posterior hyaloid observed in cases of perifoveolar PVD in patients with diabetes was not different from the one reported for partial posterior vitreous detachment in healthy patients. 1 Uchino E. Uemura A. Ohba N. Initial stages of posterior vitreous detachment in healthy eyes of older persons evaluated by optical coherence tomography. Arch Ophthalmol. 2001; 119: 1475-1479 Crossref PubMed Scopus (233) Google Scholar In these cases, the vitreoretinal separation may be considered as clean. However, the definition of a clean separation of the vitreous cortex from the macula should be clarified: it was shown in a scanning electron microscopy study that 44% of the normal eyes with apparently complete PVD exhibited vitreous cortex remnants on the retina. 2 Kishi S. Demaria C. Shimizu K. Vitreous cortex remnants at the fovea after spontaneous vitreous detachment. Int Ophthalmol. 1986; 9: 253-260 Crossref PubMed Scopus (144) Google Scholar In a clinical setting, fundus biomicroscopy and OCT examination are not sensitive enough to permit diagnosis of vitreoschisis or to determine whether the vitreoretinal separation is clean or not. Optical Coherence Tomography Assessment of the Vitreoretinal Relationship in Diabetic Macular EdemaAmerican Journal of OphthalmologyVol. 141Issue 1PreviewWe read with interest the article by Dr Gaucher and associates on optical coherence tomography findings in eyes with diabetic macular edema.1 We appreciate the systematic approach to assess the vitreomacular interface of diabetic patients by optical coherence tomography. Given our previous work on the morphology of the vitreomacular interface in eyes with diabetic macular edema and traction maculopathies, we would like to share some thoughts with the authors of this article.2,3 Full-Text PDF
