PURPOSE: The aim of the present preliminary study, performed on post-surgical hypotony, was the evaluation of the effects on ocular hypotony of the concomitant administration of ibopamine and corticosteroids.
METHODS: 14 patients (11 males-3 females; mean age 47 years) with ocular hypotony following several vitroretinal surgical intervention in different districts, were enrolled. The inclusion criteria were: mean IOP during tonometric curve equal or lower than 6 mmHg, stable IOP for at least 60 days, ongoing treatment with 0.1% dexamethasone (4 times/day), successful surgical intervention, 2% ibopamine (4 times/day) was added to the corticosteroid therapy for 30-60 days.
RESULTS: Before ibopamine administration, mean IOP was 4.07 mmHg SD 1.71. At the end of the treatment period, mean IOP increased by 89% in comparison to baseline values (+ 3.64 mmHg SD 5.57). This difference was statistically significant (paired t = 2.39; P = 0.03). One month after ibopamine-treatment discontinuation, mean IOP decreased to pre-treatment values (4.86 mmHg SD 3.50).
CONCLUSIONS: The results of the present study, although preliminary, suggest the possibility of a future pharmacological treatment of ocular hypotony with ibopamine, whose rationale is based on the increase of aqueous humor production by stimulating the D1 dopaminergic receptor.
