[Clinical evaluation of isopropyl unoprostone (Rescula), in the adjunctive treatment of primary open angle glaucoma].
OBJECTIVE
To investigate the clinical characteristics of docosanoid derivative, isopropyl unoprostone in the treatment of primary open angle glaucoma (POAG).


METHODS
In 17 patients (22 eyes) with POAG we analysed prospectively the effect of Rescula upon intraocular pressure, aqueous flare, pupil size, ocular signs and symptoms. Patients were followed up every 2 weeks for at least 8 weeks with complete ocular examination. Concomitant topical therapeutics were used in the study: 0.5% Timolol--group I (16 eyes), and 0.5% Timolol + 2% Dorzolamide--group II (6 eyes).


RESULTS
Mean (+/- SD) pretreatment pressure was 24.7 +/- 4.3 mm Hg in group I and it was reduced by 3.7 mm Hg (13.5%) (p < 0.05) at the end of the follow up. In group I Rescula was very effective (delta T% > 25%) in 6/16 eyes (37.5%) and it was ineffective (delta T% < 10%) in the same number of eyes. In group II pretreatment pressure was 24.8 +/- 2.6 mm Hg and it was reduced by 2.6 mm Hg (10.6%) (p = 0.1). Rescula induced no elevation of the aqueous flare during the treatment. No effect on pupil size was observed, either. Eye stinging/conjunctival hyperaemia was noted in 2/17 patients and punctate epitheliopathy in 1 patient (5.9%) that caused discontinuation of drops.


CONCLUSIONS
Unoprostone produced significant additive effect to Timolol. Thus, it may be a valuable option for adjunctive therapy. However, interindividual differences need to be considered, as in some patients the response was insignificant.
