Objectives To evaluate the effects of
intravenous in fusion of
mannitolum on the degree of
intraorbital pressure and
exophthalmos and investigate the clinical value of measurement of
Intraorbital pressure and exophthalmos in the diagnosis and treatment of dehydration.Methods The intraorbital pressure and exophthalmos of the normal eyes of 86 patients whose one eye had cataract and needed surgical treatment were measured before and after intravenous
infusion of mannitolum.Results The degree of intraorbital pressure and exophthalmos after infusion of mannitolum was remarkably lower than that before infusion. It reached the lowest in two hours. The intraorbital pressure was
decreased by 0. 67 kPa (P<0.01) and the exophthalmos was decreased by 2.1mm (P<0. 01 ).Conclusion Hyperosmotic agents may cause the water loss of the orbital tissue and decrease the intraorbital pressure and exophthalmos. These changes of intraorbital pressure and exophthalmos may be measured by the immediate contact orbitonometer. The measurement of intraorbital pressure and exophthalmos may provide evidence to the diagnosis and treatment of dehydration.
