March 2013. In t.t.l, 14790 FDG-PEt.and EGD procedures performed for 8468 individuals were included in t.is st.dy, and t.e performance of FDGPEt.for EC screening was assessed by comparing t.e result. of FDG-PEt.and EGD, considering t.e lat.er as t.e *** t.irt.-t.o EC lesions were det.ct.d in 28 individuals(31 squamous cell carcinomas and 1 adenocarcinoma). t.e median t.mor size was 12.5 mm, and t.e dept.s of t.e lesions were as follows: t.s(n = 12), t.a(n = 15), and t.b(n = 5). Among t.e 14790 FDG-PEt.procedures, 51 examinat.ons(0.3%) showed posit.ve findings in t.e esophagus; only 1 was a t.ue-posit.ve finding. t.e screen sensit.vit., specificit., posit.ve predict.ve value, and negat.ve predict.ve value of FDGPEt.for ECs were 3.6%(95%CI: 0.1-18.3), 99.7%(95%CI: 99.6-99.7), 2.0%(95%CI: 0.0-10.4), and 99.8%(95%CI: 99.7-99.9), respect.vely. Of t.e 50 FDG-PEt.false-posit.ve cases, 31 were observed in t.e lower esophagus, and gast.oesophageal reflux disease was observed in 17 of t.ese 31 *** t.is st.dy is t.e first.t. clarify t.e FDG-PEt.performance for EC screening. Based on t.e low screen sensit.vit., FDG-PEt.is considered t. be difficult.t. use as a screening modalit. for ECs.

Object.ve: t. evaluat. t.e prevalence and clinical feat.res of a newly recognized peripapillary lesion specific t. high myopia, peripapillary det.chment.in pat.ologic myopia (PDPM), in a large series of pat.ent. wit. high myopia. Met.ods: t.ree hundred t.ent.-four pat.ent. (632 eyes) wit. high myopia were enrolled in t.is st.dy. We examined t.e prevalence, range, fluorescein and indocyanine green angiographic findings, and opt.cal coherence t.mography findings of PDPM for t.ese pat.ent.. Visual field t.st.ng (Goldmann kinet.c perimet.y and t.e Humphrey 30-2 program) was also performed in t.e pat.ent. wit. PDPM. Result.: Peripapillary det.chment.in pat.ologic myopia was ident.fied in 31 of 632 highly myopic eyes (4.9%)-. t.e opt.cal coherence t.mographic scan across t.e PDPM lesion revealed a localized det.chment.of ret.nal pigment.epit.elium adjacent.t. t.e opt.c nerve. Alt.ough PDPM was always sit.at.d adjacent.t. t.e inferior edge of t.e opt.c disc, in some pat.ent. it.surrounded almost.t.e ent.re opt.c disc. t.ere was a st.ep excavat.on of t.e inferior myopic conus adjacent.t. t.e PDPM, and t.e inferot.mporal ret.nal vein was markedly bent.at.t.e t.ansit.on from t.e PDPM t. t.e excavat.d myopic conus. Glaucomat.us visual field defect. were frequent.y det.ct.d in eyes wit. PDPM (71.0%). Conclusions: t.e findings of t.is st.dy indicat. t.at.PDPM is not.uncommon among highly myopic eyes. Alt.ough it. pat.ogenesis and pat.ologic significance require furt.er classificat.on, PDPM might.be anot.er indicat.r of visual field defect. in high myopia.
