Objectives: to study the oculo- hypotensive effect of non-selective phosphodiestrase inhibitor aminophylline. Methods: The study was conducted on fifteen albino rabbits (2.5–2.8 Kg) and model of acute ocular hypertension was obtained by 5% glucose water administration at 15ml/kg through the marginal vein of the rabbit’s ear. Aminophylline was dissolved in vehicle of phosphate buffer saline and diluted to desired concentration as 0.5%. Phosphate buffer saline solution also served as control. The left eye of rabbit was received one drop of aminophylline (0.5%) on the other hand the right eye treated by the vehicle and considered as control parameter. The pressure measurement was recorded at 15, 30, 45, 60, 90, 120, 135, 150 and 165 min after drug instillation. Results: After 30 minutes of topical 0.5% aminophylline administration the normal tension of the eye remain unchanged. However topical 0.5% aminophylline eye drop significantly (p < 0.05) successes in the decrease of the acute elevation of ocular pressure due to 5% glucose infusion. Moreover, in this study aminophylline pretreatment has the ability to facilitating the returns of the IOP to normal levels Conclusions: Topical administration of aminophylline (0.5%) significantly prevent acute rise in the ocular pressure induced by 5% glucose administration. The IOP lowering effect of aminophylline can be considered as potential antiglaucoma drug.
