Active clinical trials for "Macular Edema"

Patients with diabetic macular edema (DME) or uveitis-related macular edema who have failed first-line therapy such as anti-VEGF, laser treatments, or dexamethasone implants (DXM) are candidates for treatment with an intravitreal injection of a fluocinolone acetonide (AcF) implant. AcF is unique in that it delivers intravitreal corticosteroids for 2 to 3 years, whereas DXM only releases them for 3 to 6 months. After 6 months for AcF and 1 month for DXM, full therapeutic efficacy is attained. AcF's safety and efficacy have now been confirmed in the FAME originator studies as well as other phase IV investigations. However, in the FAME princeps trials and numerous phase IV trials where patients got AcF more than 6 months after DXM, up to 40% of patients required laser, anti-VEGF, and/or DXM retreatment within the AcF active period. This high rate could be attributed to AcF's 6-month delay in reaching full efficacy. This is why the investigators intended to replicate the previous Iluvi1-month research, which shown that injecting DXM at 1 month preserved visual acuity and central retinal thickness for the first 6 months without increasing intraocular pressure significantly. The study, however, was unable to determine the long-term impact on the rate of relapses requiring additional therapy as well as tolerance with the development of long-term cortisone-induced glaucoma. In light of this, the investigators should like to gather new data for a 3-year follow-up after AcF injection, including measurements of optic nerve fibre thickness (OCT RNFL). This is an essential safety data point because it assesses the long-term effects of ocular hypertension, which is a well-known side effect of intravitreal corticosteroids.

Vitrectomy is required for removal of vitreous hemorrhage or retinal traction tissue in some patients with proliferative diabetic retinopathy. Post-vitrectomy macular edema may occur in these diabetic patients. Intravitreal injections of anti-VEGF agents or corticosteroid are required for treating diabetic macular edema (DME) in vitrectomized eyes. Intraocular levels of various cytokines may alter in the diabetic eyes following vitrectomy. Pharmacokinetics may be different between various intraocular agents in vitrectomized eyes. Herein our study will prospectively randomize to compare the clinical behavior between intravitreal ranibizumab (IVR) and intravitreal dexamethasone implant (IDI) in vitrectomized patients with DME. To our knowledge, it is the first study involving such subject.

This is an open-label, Phase I/II study evaluating intravitreal ranibizumab (R) vs. intravitreal Triesence (triamcinolone acetonide) (T) in subjects with acute pseudophakic cystoid macular edema (CME). Twenty consented patients with acute CME after phacoemulsification cataract surgery with posterior chamber intraocular lens implantation (PE/PCIOL) will be randomized 1:1 to treatment with R or T. R patients will receive three monthly R injections, followed by PRN dosing. T patients will receive PRN injections every 3 months. Clinical CME is defined as clinically evident CME, with visual acuity (VA) typically in the 20/40 to 20/200 range. Re-treatment criteria will include clinically evident worsening of CME, combined with any of the following: Any increase in spectral domain ocular coherence tomography (OCT) central macular thickness (CMT) Any observable fluid on OCT Any qualitatively increased perifoveal leakage/pooling on fluorescein angiography (FA). Patients will be followed monthly through 12 months.

To evaluate the relative efficacy of three commonly utilized regional corticosteroids for the regional treatment of uveitic macular edema: periocular triamcinolone acetonide; intravitreal triamcinolone acetonide; intravitreal dexamethasone implant. The primary efficacy measure will be percent change in central subfield thickness as measured by OCT at 8 weeks. Participants will continue in the study for 24 weeks in order to evaluate relative effects of the 3 treatment strategies on the duration of treatment effects, requirement for additional injections, and adverse effects. Note: The planned sample size for the POINT Trial was 267 subjects. On 17 July 2017, with 192 subjects enrolled, the Data and Safety Monitoring Committee (DSMC) reviewed the planned interim analysis and recommended that the goals of the trial could be accomplished by completing follow-up of enrolled subjects without the recruitment of additional subjects. Per the DSMC recommendations, recruitment was suspended and follow-up of enrolled subjects was completed according to the protocol.

The current application proposes to conduct a prospective, clinical trial in diabetic subjects with diabetic macular edema (DME) to evaluate the therapeutic efficacy of 670 nm photobiomodulation on validated clinical outcome measures and anatomical changes in central macula by optical coherence tomography (OCT) and other imaging modalities. A total of 30 diabetic patients with treatment-refractory clinically significant diabetic macular edema will be included in this study and randomized into two equal groups. One eye per participant will be included to avoid exposure of both eyes to the study intervention. If both eyes are eligible, the eye with worse visual acuity will become the study eye. One group will be treated with standard-of-care (intravitreal anti-VEGF agent) injections. The photobiomodulaton (PBM) intervention group will be treated with the standard-of-care intravitreal anti-VEGF (vascular endothelial growth factor) injections and 670 nm PBM in one eye. Baseline functional and anatomic assessments will be made and anti-VEGF therapy will be administered as determined by the treating Ophthalmologist.

This trial seeks to prove that sub-lethal laser power levels are as effective and less damaging than traditional laser. Diabetic macular edema (DME) affects approximately 29% of diabetic patients with a disease duration of 20 or more years and is one of the most frequent causes of vision loss in this population. The Early Treatment Diabetic Retinopathy Study (ETDRS) demonstrated a significant benefit of laser photocoagulation for the treatment of clinically significant macular edema, reducing the incidence of vision loss by approximately 50% at 3 years' follow-up.

Glaucoma, a progressive optic disc neuropathy causing visual field reduction, is the second leading cause of world blindness. The treatment of glaucoma is mainly based in reducing intraocular pressure (IOP) with topical medications. Many patients required two or more medications to achieve a target IOP. Combinations of B-blockers and prostaglandin analogs (PGA) are frequently used in clinical practice because their additive effect in lowering IOP levels. The aim of this study was to investigate the effects of fixed combinations of timolol maleate and PGA on the blood-aqueous barrier and evaluate the measurement of foveal thickness in pseudophakic patients with primary open-angle glaucoma (POAG).
