Carbonelli et al Figure 1 Fundus photography with a line showing the OCT scan.The photograph demonstrates the presence of a tilted disc surrounded by a slightly elevated yellow- orange lesion, consistent with a PPRD, which hampered visualization of the underlying choroidal vessels. The nonreﬂective space extended temporally up to 1.1 mm from the fovea. No epiretinal membranes were detected. The scans crossing the optic nerve head conﬁrmed the lack of an optic disc pit. Neither FA nor indocyanine green angiography (ICGA) disclosed any choroidal neovascularization. Discussion Myopia-associated PPRD has been recently described as a distinct entity. Three papers have reported the OCT ﬁndings of such a condition (Freund et al 2003; Toranzo et al 2005; Shimada et al 2006). Shimada and coauthors (2006) described the largest series (31 eyes): in all cases OCT revealed a local- ized detachment caused by ﬂuid accumulation beneath both the neurosensory retina and the RPE. Previous case reports had already described similar ﬁndings. Although Toranzo and coauthors (2005) claimed signiﬁcant differences when illustrating their case in comparison to those reported by Bailey Freund and coauthors (2003) (they also gave a dif- ferent name to this condition: intrachoroidal cavitation), a careful analysis of the pictures that both groups published actually reveals quite similar features, including a localized detachment of the RPE and retina and a ﬂat proﬁle of the RPE. Fluorescein angiography (FA) also showed similar 328 images, revealing among other things the lack of the early, localized hyperﬂuorescence that would be expected in case of RPE detachment. On fundus examination the case herein reported was quite similar to those previously described, due to the presence of the peripapillary, slightly elevated yellow-orange lesion precluding visualization of the underlying choroidal vessels; the extension into the temporal and superior quadrants (in addition to the inferior one) has already been reported (Freund et al 2003). OCT, however, provided quite a different picture. The detachment, in fact, was located between the neurosensory retina and the RPE, which was still in contact with the choroid. Given the presence of bridging tissue between the RPE and the neuroretina, it would seem more appropriate to deﬁne this space as an outer retinal schisis, which is not typical of myopic PPRD. Retinal schisis may be found in association with an optic disc pit, but in this case the inner retinal layers are usually involved (Rutledge et al 1996); since no optic disc anomalies were observed in our patient, we felt that this diagnosis could be reasonably ruled out. Outer retinal schisis can be observed in myopic macular retinoschisis, although in such a case the central macula is involved, not the peripapillary retina (Benhamou Clinical Ophthalmology 2007:1(3)
