bimatoprost and Chronic-Disease

The aim of this study was to compare the long-term efficacy of bimatoprost 0.03% monotherapy in primary open angle glaucoma (POAG) versus primary chronic angle closure glaucoma (PCACG) eyes.. A total of 55 consecutive primary adult glaucoma patients on bimatoprost monotherapy were prospectively evaluated in this 3-year, open-labeled, uncontrolled study. The primary outcome was the evaluation of a difference in the response to therapy of POAG eyes, as compared to PCACG eyes over a follow-up of 3 years.. In the POAG group, the mean intraocular pressure (IOP) at the 36-month followup was found to be increased by 2.10 (+/-3.90) mmHg (confidence interval [CI], 0.975-4.185), compared to the mean IOP at 1 month (P = 0.047). In the PCACG group, the mean IOP at the 36-month follow-up was increased by 3.66) (+/- 3.34) mmHg (CI, 6.241-1.092), compared to the mean IOP at 1 month (P = 0.011). This upward drift in IOP was higher in the PCACG group, compared to the POAG group, but this was not statistically significant (P = 0.54). Patients with POAG and PCACG showed a 50% and 40% chance of having an IOP of <18 mmHg with bimatoprost monotherapy (P = 0.23), respectively, at the 3-year follow-up.. This study showed that bimatoprost 0.03% monotherapy significantly lowers IOP in both POAG and PCACG eyes over a period of 3 years, though its efficacy appeared to decrease over time, to a similar extent, in both groups.

The aim of this study was to compare the intraocular pressure (IOP)-lowering effect of latanoprost and bimatoprost as primary therapy in patients with chronic angle-closure glaucoma (CACG) after peripheral iridotomy.. Eighty-two (82) consecutive CACG patients with an IOP greater than 19 mmHg after a peripheral iridotomy were recruited. CACG was defined as chronic elevated IOP, glaucomatous optic neuropathy, and a corresponding visual field defect in eyes with occludable angle and peripheral anterior synechiae on gonioscopy. Patients were randomly assigned to two groups based on daily treatment with either latanoprost 0.005% or bimatoprost 0.03% in the evening for 12 weeks. The IOP was measured at 9 AM and 4 PM on the same day at baseline and also at 4, 8, and 12 weeks. Between-group differences in mean diurnal IOP and IOP reduction were analyzed.. After 12 weeks of treatment, mean IOP for both the latanoprost and bimatoprost groups was significantly reduced when compared to the baseline value (21.6 +/- 1.9 to 16.4 +/- 2.5 mmHg and 22.1 +/- 2.0 to 16.9 +/- 2.4 mmHg, respectively; P < 0.001 for both). There was no significant difference in IOP reduction between the two treatment groups (P = 0.40). At 4 and 8 weeks, the IOP changes from baseline were statistically significant at both times for both drugs (all P < 0.001).. Both latanoprost and bimatoprost significantly reduced IOP in CACG patients who were inadequately treated by laser peripheral iridotomy.

The aim of the present prospective masked study was to assess the effect of bimatoprost monotherapy on ocular blood flow and intraocular pressure (IOP) in eyes of primary chronic angle closure glaucoma patients already on concomitant timolol and pilocarpine. Thirty two patients of bilateral primary chronic angle closure glaucoma (PCACG) on topical timolol 0.5% twice a day and pilocarpine 2% three times daily were switched over to bimatoprost 0.03% once daily in both eyes. Intraocular pressure (IOP) and pulsatile ocular blood flow (POBF) were recorded before and after starting bimatoprost and were followed up every four weeks for three months. Bimatoprost had statistically significant (p < 0.05) mean IOP reduction from 19.3 +/- 6.6 to 13.5 +/- 4.5 mmHg (30.5%) and there was improvement from 858 +/- 260 to 1261 +/- 321 microL/min (46.8%) in mean pulsatile ocular blood flow (p < 0.05). Conjunctival hyperemia (32%) was the most common adverse effect of bimatoprost. Bimatoprost 0.03% monotherapy improved ocular blood flow and provided a better diurnal IOP control than concomitant timolol-pilocarpine in eyes with primary chronic angle closure glaucoma and was found to be well tolerated.
