Active clinical trials for "Macular Edema"

To investigate the incidence of cystoid macular edema in eyes with primary rhegmatogenous retinal detachment successfully treated with vitrectomy with gas tamponade, and to evaluate the clinical variables associated with its development.

To increase the clinical experience of using the rtx1 camera in various retinal disorders and to follow the evolution of structural alterations during retinal diseases using adaptive optics imaging with the rtx1 camera

This is a 24-week, prospective, multi-center, open-label, randomized, investigator-initiated pilot study to explore the effects of RBZ (0.5 mg) plus DEX implant (0.7 mg) PRN combination therapy (n = 30) vs. DEX implant PRN monotherapy (n = 30) in pseudophakic eyes with center-involved DME that have demonstrated prior incomplete response to 3-6 anti-VEGF treatments.

Background: - People with rod-cone dystrophy (RCD) or enhanced S-cone syndrome (ESCS) have excess fluid under the retina of their eye. This can cause vision loss. The medicine interferon gamma-1b may help people with these diseases. Objectives: - To see if interferon gamma-1b eyedrops are safe for people with RCD or ESCS. To see if the medicine can decrease retina fluid and help prevent vision loss. Eligibility: - People at least 12 years old with RCD or ESCS. Those with ESCS must have two mutations in the NR2E3 gene. Design: Participants will be screened with medical history, physical exam, eye exam, and blood tests. Participants will stay at NIH for 3 days and get the first eyedrops. Participants will give themselves 4 study eyedrops 4 times daily for 2 weeks and keep a diary. Participants will have 5 outpatient visits over 8 weeks, 2 of which are telephone assessments. They may have: Repeats of screening tests. Questionnaires. Small piece of skin removed. Eye exams, including eye dilation and tasks on computer screens. Fluorescein angiography. A dye injected into an arm vein will travel to the blood vessels in the eyes. A camera will take pictures. Electroretinography. Participants will sit in the dark wearing eyepatches. A small electrode will be taped to the forehead. After 30 minutes, researchers will remove the eyepatches and put in numbing eyedrops and contact lenses. Participants will watch flashing lights. Electrooculography. Electrodes will be attached outside of the eyes and eye function will be measured in the dark and the light. Participants will have a follow-up visit after 52 weeks.

This research study is being conducted to determine the safety and tolerability of subconjunctival injections of aflibercept in the treatment of pseudophakic cystoid macular edema that has not responded well to first-line standard of care treatment (eye drops). Pseudophakic cystoid macular edema (CME) is swelling of the retina that can occur weeks or years after cataract surgery and typically results in decreased vision. Subconjunctival injections are injections placed just beneath the clear membrane (conjunctiva) of the eye. A recent report of one patient who received two subconjunctival injections of a similar medication to the one being studied here indicated that subconjunctival injections of this class of medication may be an effective and less invasive alternative to intravitreal injections for pseudophakic CME. Because of the similarity of the drugs and the patient's treatment success, we would like to see if subconjunctival injection(s) of aflibercept will work in treating pseudophakic CME. If successful, the risk of an intraocular infection and glaucoma that comes with standard of care treatments might be greatly reduced.

The purpose of this study is to determine the effect of ranibizumab for the treatment of macular edema (ME) secondary to branch retinal vein occlusion (BRVO) in patients with initial fair visual acuity.

The study was designed to assess the efficacy and safety of Lucentis® (ranibizumab 0.5 mg) in diabetic patients presenting with reduced visual acuity due to diabetic macular edema and evaluating spacing out of follow-up after initial intensive treatment phase.

In this study, the investigators aim to use light masks (Noctura 400) to test the hypothesis that preventing the dark adaptation and associated hypoxia of the rods in the eye could in turn prevent or halt the progression of centre-involving Diabetic Macular Oedema (DMO). DMO is a devastating disease that is the most common cause of registerable blindness in the working age-group in the United Kingdom (UK) This is a multi-centred randomised controlled trial involving 240 patients. Post randomization, participants in the intervention arm will wear the Noctura 400 Light Mask at night for 48 weeks in conjunction with their routine, prescribed treatment of intravitreal (eye) ranibizumab. Those in the standard arm will receive their routine, prescribed ranibizumab treatment only. The primary objective is to determine whether utilizing the Noctura 400 Light Mask at night reduces the number of intravitreal injections of ranibizumab required by patients undergoing such a course for the treatment of DMO.

BACKGROUND: Uveitis comprises of a group of diseases associated with inflammation of the eye that can lead to vision loss. Some people with uveitis also have macular edema (swelling of the retina at the back of the eye). Uveitis and macular edema are treated with medications and sometimes surgery, but treatment does not always prevent vision loss. Previous research has shown that injections of methotrexate into the eye of people with eye disease other than uveitis can help relieve the inflammation, or swelling, that causes macular edema and can slow visual loss. However, it has not yet been approved as a treatment for macular edema associated with uveitis. OBJECTIVES: To evaluate the safety and effectiveness of methotrexate injections as a treatment for macular edema associated with uveitis. ELIGIBILITY: Individuals at least 18 years of age who have been diagnosed with uveitis and macular edema in at least one eye. DESIGN: This study requires at least nine visits to the National Eye Institute study clinic over a period of 6 months (24 weeks). Participants will be screened with a physical and ophthalmic examination, medical history, blood and urine tests, and additional eye and other tests as needed. Participants will receive a methotrexate injection in a selected treatment eye. After the injection, participants will receive antibiotic eye drops to place in the eye three times a day for the 3 days following the injection, leucovorin (folic acid) drops to place in the eye four times a day for 1 week following the injection, and a dose of folic acid to be taken by mouth the day after the injection. Participants who tolerate the initial injection may continue to receive injections in their study eye every month for 6 months. After 6 months, participants who show improvement from the injections may be evaluated to receive additional injections every 4 to 8 weeks until researchers end the study.

The purpose of the present study is to examine, if retinal swelling in diabetic patients can be reduced by an intravenous injection of galactose.
