Summary

In eight normal rabbits, sodium acetazolamide (5.5 mg per kg of body weight) in 11% solution was injected subconjunctivally daily for about four weeks in the left eye of each rabbit, with the right eye serving as a control. Ocular tension in both eyes was measured by the Perkins hand-held applanation tonometer. Five of the eight rabbits showed a significant difference (P < 0.05) in ocular tension between treated and untreated eyes, with a decrease in the treated left eye. The ocular tension decrease in the treated left eye began about one week after the beginning of the injections and lasted for about two weeks. Thereafter, ocular tension in the treated left eye returned to base-line levels, despite continued subconjunctival injection of sodium acetazolamide.

Zusammenfassung

Bei 8 Kaninchen wurden Sodium Acetazolamide (5,5 mg pro Kilogramm Körpergewicht) in einer 11%igen Lösung subconjunctival unter die Bindehaut des linken Auges von jedem Kaninchen injiziert, während das rechte Auge zur Kontrolle diente. Der intraoculare Druck wurde in beiden Augen mit dem Handapplanationstonometer nach Perkins gemessen. Fünf der acht Kaninchen zeigten einen signifikanten Unterschied (P < 0,05) im intraocularen Druck zwischen dem behandelten und unbehandelten Auge mit einem Abfall im behanddelten Auge. Der Abfall des intraocularen Druckes in dem behandelten Auge begann ungefähr eine Woche nach dem Einsetzen der Injektionen und hielt für ungefähr 2 Wochen an. Danach kehrte der intraoculare Druck in den behandelten Augen zu den Ausgangswerten zurück trotz Fortsetzung der subconjunctivalen Injektionen von Sodium Acetazolamiden.
