Octopus視野計のプログラムFから得られた断面静的視野を用いて,糖尿病性黄斑症の5病型(類嚢胞黄斑浮腫(cystoid macular edema,CME),単純黄斑浮腫(simple macular edema,SME),黄斑沈着物,乏血性黄斑症,糖尿病性色素上皮症)の視野変化について検討し,次の結果が得られた。
(1)各病型とも,網膜感度曲線にジグザグした不規則な低下が認められた。
(2)網膜感度の低下の程度と視力低下の程度は,必ずしも一致しなかった。
(3) CME, SMEでは,軽度な網膜感度曲線の低下をみた。
(4)強い沈着物,人きな無血管帯,網膜色素上皮の障害部では,中等度以上に網膜感度は低下していた。
We evaluated the central visual field in 23 eyes, 17 cases, with macular involvement in diabetic retinopathy. The cases showed cystoid or simple macular edema, macular deposits, ischemic or dia-betic pigment epitheliopathy. Funduscopic and fluorescein angiographic findings were compared against central campimetric findings as tested by program F of automated perimetry system byOctopus.
The sensitivity in the central retina was de-creased in variable degrees throughout the series. This decrease in sensitivity did not correspond to impaired visual acuity. The sensitivity was impair-ed minimally in eyes with simple or cystoid macular edema and moderately in eyes with macular deposits, extensive avascular area or damaged retinal pigment epithelium.
