Introduction:
Anterior segment ischaemia manifesting in aqueous malformation may follow tenotomy of the extraocular muscles.
Material And Methods:
Tenotomy of 2 or 4 rectus eye muscles was performed on the right eyes of 23 adult rabbits. The aqueous humor was withdrawn from the anterior chamber of both eyes in 7 rabbits on the 11th, on the 22nd in 8 and on the 32nd postoperative day in 8 rabbits. Aqueous natrium, potassium and glucose concentrations and protein electrophoresis were examined.
Results:
The only significant change was lower mean aqueous potassium concentration in the operated eyes as compared to controls on the 11th postoperative day.
Conclusion:
Tenotomy of rectus eye muscles in healthy rabbits evoked a discrete blood-aqueous barrier break-down.
