自動視野計（Topcon SBP-1000）の使用経験

Clinical evaluation of a new automated perimeter (Topcon SBP-1000)

　我々の開発した自動視野計（Topcon SBP-1000）を臨床に使用し，ゴールドマン視野計による動的視野と比較した．緑内障，視神経疾患，半盲，網膜疾患，その他の例において，視野異常をよく検出することができ，特に，初期の視野異常の検出に優れていた．

　本視野計には，閾上刺激による静的測定と閾値測定の豊富なプログラムがあり，また，自動的な測定の他，任意の部位を細かく測定することもできる．短時間でスクリーニングと詳細な測定が可能で，臨床的に有用な視野計である．

We evaluated a new automated perimeter for static perimetry, Topcon SBP-1000. Light-emitting diodes are mounted in a hemispherical dome and are controlled by a microcomputer system. Nine suprathreshold static programs and 4 threshold programs are available. We examined 122 patients with glaucoma, optic neuropathy, hemianopsia, retinal pigment degeneration among others with this perimeter. Manually operated Goldmann ki-netic perimeter was used for comparison.

As an overall evaluation, the use of automated perimeter resulted in a higher rate of detection of pathological visual field, particularly light-grade ones. Also, areas of depressed retinal sensitivity were judjed as severer than with kinetic perimetry. Small and/or sieve-like scotoinata were more readily de-tected. The automated perimeter was thus judged as to be of value in routine clinical use.
