前増殖糖尿病網膜症の細分類と前房フレア値

Subclassification of preproliferative diabetic retinopathy and aqueous flare intensity

　Davisらの分類における前増殖糖尿病網膜症148眼を，3主要所見（軟性白斑，血管閉塞領域，静脈の数珠状拡張）の組み合わせにより3群に細分類し，前房フレア値を検討した．また対照として，単純網膜症59眼，増殖網膜症79眼との比較をあわせて行った。前増殖網膜症における前房フレア値は，軽症，中等症，重症の順に高くなり，それぞれの間に有意差を認めた。

　また，単純網膜症と前増殖網膜症・軽症，増殖網膜症と前増殖網膜症・重症との間には，前房フレア値に有意差はなかった。

　この結果から，前房フレア値の面からも筆者らの細分類の妥当性が示されたと考えた。

We quantitated the aqueous flare intensity in 148eyes with preproliferative diabetic retinopathy(PPDR). The eyes were divided into 3 subgroups:mild type showing soft exudates but no apparentnonperfusion, moderate type with soft exudates andnonperfusion, and severe type with additionalvenous beading. The aqueous flare become moreintense from mild through moderate to severe type.The difference among the 3 groups was significant (p＜0.05). We also quantitated the aqueous flareintensity in 59 eyes with simple retinopathy and 79eyes with proliferative retinopathy. The flare inten-sity in simple retinopathy was significantly less than in moderate or severe types of PPDR (p＜0.002). No difference was present between simpleretinopathy and mild type of PPDR. Flare intensityin proliferative retinopathy was higher than insimple retinopathy and moderate type of PPDR (p ＜0.001). No difference was present betweensevere type of PPDR and proliferative retinopathy.Above findings seemed to show the adequacy of thepresent method of subclassification of PPDR.
