cloprostenol and Pseudophakia

To investigate the effects of prostaglandin analogues on the blood-aqueous barrier and to evaluate the occurrence of cystoid macular edema in aphakic or pseudophakic patients with glaucoma.. In this randomized, masked-observer, 6-month clinical trial, patients with primary open-angle, pseudophakic, or aphakic glaucoma were treated once daily with bimatoprost (n = 16), latanoprost (n = 15), or travoprost (n = 17) or twice daily with unoprostone (n = 16) or lubricant drops (control group) (n = 16). Blood-aqueous barrier status, which was assessed using a laser flare meter; intraocular pressure; the occurrence of angiographic cystoid macular edema; and conjunctival hyperemia were evaluated.. Mean flare values were significantly higher in the bimatoprost, latanoprost, and travoprost groups throughout follow-up (P < .02). Four latanoprost-treated eyes, 1 bimatoprost-treated eye, and 1 travoprost-treated eye developed cystoid macular edema; all cases resolved after discontinuation of the prostaglandin analogue and treatment with topical diclofenac sodium. Mean intraocular pressure reductions after 6 months were higher for the latanoprost (26%), bimatoprost (28%), and travoprost (29%) groups than for the control (3%) and unoprostone (14%) groups (P< .05). Bimatoprost induced significantly higher hyperemia scores than latanoprost, unoprostone, and placebo (P< .01).. Bimatoprost, latanoprost, and travoprost use may lead to disruption of the blood-aqueous barrier in patients with pseudophakia and aphakia.

The aim of this study was to report a case of cystoid macular edema (CME) in a pseudophakic patient after switching from latanoprost to BAK-free travoprost.. This study is presented as an interventional case report.. Clinical examination showed the development of CME, proven by ocular coherence tomography, after institution of BAK-free travoprost in a patient that was previously treated with Latanoprost. Ocular signs and symptoms responded to stopping travoprost and treatment with topical prednisolone and non-steroidal anti-inflammatory medicines. The intraocular pressure was successfully controlled with brimonidine tartrate 0.15%.. CME is a known adverse effect of all prostaglandin analogs. However, our patient developed this complication after being switched from latanoprost to BAK-free travoprost. This may be due to exacerbation of a previously undiagnosed CME or to the ionic-buffered preservative system (sofZia) alone or in combination with travoprost unique to this product. It is prudent to exercise caution in the use of prostaglandin analogs and prostamides especially in high-risk eyes.

Prostaglandin-like drugs such as latanoprost (Xalatan), travoprost (Travatan) and bimatoprost (Lumigan) lower the intraocular pressure by improving the outflow of aqueous humor via the uveoscleral pathway. Up to now there is no report about a macular edema after the topical use of Lumigan eye drops in a pseudophakic patient with an intact posterior capsule.. A 69-year-old pseudophakic patient with a 14-year history of glaucoma in pseudoexfoliation syndrome, revealed a cystoid macular edema after local treatment with bimatoprost . 6 months earlier a phakoemulsification followed by the insertion of a posterior intraocular lens was performed on the left eye. Due to an elevated intraocular pressure after the surgery, which could not be controlled either by several eyedrops, or by three more operations (one viscocanalostomy with mitomycin c, two cyclophotocoagulations), therefore, a final attempt with bimatoprost (Lumigan) was started. Two weeks later the patient complained of blurred vision, caused by a cystoid macular edema.. After discontinuation of bimatoprost and initiation of a local and systemic anti-inflammatory therapy, the edema resolved and visual acuity recovered.. Bimatoprost (Lumigan) , a synthetic prostamid is similar to human prostaglandins, especially to prostaglandin F (2alpha.) Although it does not bind to the same receptor, its side effects are comparable to those of common prostaglandin analogues. So far there are no reports about the manifestation of a macular edema after using bimatoprost in pseudophakic eyes with an intact posterior capsule. Even if three more operations followed the cataract surgery, we suspect that bimatoprost eyedrops can be held responsible for this. Therefore they should be used with great care and in clear indications, particularly in pseudophakic patients.

To report a case of angiographically documented cystoid macula edema occurring after switching a pseudophakic patient from latanoprost to bimatoprost.. Observational case report.. A 68-year-old man developed intense conjunctival hyperemia and cystoid macula edema after switching from latanoprost to bimatoprost 9 months after cataract surgery in an eye at low-risk for this cystoid macular edema.. Bimatoprost was discontinued and diclofenac initiated. After 2 months, visual acuity and ocular hyperemia returned to baseline levels. Fundus examination revealed resolution of cystoid macula edema.. It is possible that pseudophakic eyes that develop intense conjunctival hyperemia associated with ocular hypotensive lipids might be at higher risk for developing cystoid macula edema.
