Macular Edema, Epiretinal Membrane
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.
CYSTOID MACULAR EDEMA
Background: - Some people with retinitis pigmentosa (RP) have macular edema (swelling) in the central retina. This can cause decreased central vision. The cause of macular edema is unknown, but may involve inflammation. The drug minocycline might help prevent inflammation and therefore might help treat macular edema and improve central visual function . Objectives: - To see if minocycline helps people with RP and macular edema. Eligibility: - People 12 years and older with RP who have macular edema in at least on eye. Design: * Participants will be screened with medical and eye disease history. They will have an eye exam and blood tests. One eye with macular edema will be the study eye. If both eyes are affected, one will be designated the study eye. * Participants will visit the clinic at least 9 times over at least 14 months. The first 3 study visits will be monthly, then every 2 months. * Participants will start taking minocycline after visit 3. They will take 1 pill twice daily for at least 1 year. * Participants will keep a medicine diary and bring it to each visit with their pill bottle and unused pills. At each study visit, participants will have some or all of the following tests: * eye and thyroid exams * blood and pregnancy tests * microperimetry: participants will press a button when they see a light on a computer screen * visual field measurement: participants will look at spots on a white screen to test side vision * electroretinogram: A person will be dark adapted by sitting in the dark for 30 minutes. After the placement of numbing eye drops, special contact lenses will be placed . The participant will watch flashing lights and recordings will be made.

Post-surgical Cystoid Macular Edema (PSCME)
The purpose of the study is to determine where a sustained steroid delivery system (Ozurdex,Allergan) is safe and effective to treat Cystoid Macular Edema in diabetic patients after Cataract Surgery
Pseudophakic Cystoid Macular Edema,, Diabetic Macular Edema
Background: * Uveitis is a serious inflammatory condition that affects the eye and can cause vision loss. A common secondary problem associated with uveitis is macular edema (swelling). The macula is the part of the eye that is important for central vision, and swelling of the macula can lead to further vision loss. This condition is usually treated by medicines that target the immune system, but these medicines sometimes do not work or may cause side effects. * Interferon gamma-1b (Actimmune(Registered Trademark)) is a bioengineered protein that can alter the way inflammatory cells work in the immune system. Interferon gamma-1b is given as an intramuscular injection; however, this study will use the drug as an eye drop. This study represents the first time that interferon gamma-1b is given as an eye drop. Researchers hope that interferon gamma-1b will treat macular edema by decreasing the swelling in the back of the eye. Objectives: - To investigate the safety and effectiveness of treating uveitis-associated macular edema with interferon gamma-1b. Eligibility: - Individuals 18 years of age and older who have been diagnosed with macular edema associated with uveitis (in one or both eyes) for at least 3 months. Design: * Participants will have three planned clinic visits during this study over the course of 2 weeks. * All participants will have a medical history and eye examination. * When receiving the drops, participants will have optical coherence tomography (a detailed scan of the retina) 60 minutes and 30 minutes before the drops; upon receiving the drops; and 30, 60, and 120 minutes after receiving the drops. * After receiving the drops, participants will have another eye examination, blood drawn for samples, and further scans. * Participants will be asked to return to the NIH Clinical Center 1 week after receiving the drops for an evaluation....
Uveitis
Uveitic Cystoid Macular Edema (CME) is a major cause of visual loss associated with uveitis. Systemic and/or local corticosteroid therapy and systemic immunosuppression with steroid-sparing agents such as cyclosporine, methotrexate, azathioprine, or others, effectively treats uveitis and associated CME in many patients. However, in many cases, CME persists in spite of adequate suppression of uveitis. No consensus exists on how best to treat such cases. The further addition of immunosuppressive agents appears to have little effect on this form of CME. Oral corticosteroids are useful, but high dosage and prolonged use can be associated with serious side-effects. Periocular and intravitreal corticosteroid injections are associated with well-known, significant side effects such as glaucoma and cataract formation. Vascular endothelial growth factor (VEGF) is suspected to play a role in the loss of vascular integrity in the eye and known to be induced by inflammatory cytokines, such as interleukin interleukin (IL)-1β and IL-6, which are elevated intraocularly in uveitis. In addition, it has been demonstrated that aqueous VEGF concentrations are statistically significantly higher in those uveitis patients with CME than those without CME. Inhibition of inappropriate VEGF activity is a potential approach to treatment of CME in uveitis given our current knowledge of the pathophysiology of this condition and also because of the clinical need for additional treatment options for these patients. Ranibizumab, a recombinant, humanized monoclonal antibody antigen-binding fragment (Fab) that neutralizes all active forms of VEGF-A, would target this pathway and may be useful in cases of persistent CME in uveitis patients. The objective of this study is to determine if an anti-VEGF agent, Lucentis, is safe and effective in leading to regression of macular edema due to chronic non-infectious uveitis in patients with well-controlled uveitis.
Uveitic Cystoid Macular Edema
According to a recent estimate more than 280,000 people in the United States are affected by uveitis each year. This report, also estimated that uveitis is the reason for 30,000 new cases of blindness/year and up to 10 percent of all cases of blindness. The purpose of this trial is to determine the effectiveness of VEGF blockade with intravitreal pegaptanib in patients with uveitic CME.
Uveitis, Cystoid Macular Edema
A small percentage of patients with retinal degeneration accumulate fluid in the center of their retina. Previous studies using an oral form of treatment has been successful in decreasing this fluid which improves vision. This study will test the use of a topically applied form of this treatment to the eye to reduce the amount of fluid and improve or preserve vision.

Acute Pseudophakic Cystoid Macular Edema
The objective of this study is to determine if twice-daily dosing of prednisolone (Pred Forte) is as effective as four-times-daily dosing of prednisolone for the prevention of retinal thickening and cystoid macular edema (CME) when either regimen is used concomitantly with twice-daily bromfenac.
Cystoid Macular Edema,, Retinal Thickening
This research is being done to look at the effects of Bromfenac, also called Xibrom for the treatment of swelling in the retina (the light sensitive tissue in the back of the eye) called "macular edema" that occurs after cataract surgery. Swelling in the retina can lead to blurry vision. The most commonly used treatment is eyedrops that decrease inflammation and may help stop some of the swelling. The investigators want to see if the drug Bromfenac(Xibrom) can decrease the swelling in the retina after cataract surgery and improve vision in these patients.
Cystoid Macular Edema
This research is being done to look at the effects of an experimental drug called pegaptanib (also called Macugen) for the treatment of swelling in the retina (the light sensitive tissue in the back of the eye) that can occur after cataract surgery. Swelling in the retina can lead to blurry vision. The only treatment available for this condition is eye drops that decrease swelling in the back of the eye, but eye drops may not decrease the swelling in everyone. We want to see if pegaptanib can decrease swelling in the retina and improve vision in patients with swelling after cataract surgery.
Cystoid Macular Edema
The goal of the LEOPARD clinical trial is to investigate a new kind of steroid eye drops, OCS-01. Macular edema is a condition in which there is collection of fluid (edema) in the back of the eye (Macula) and it can lead to severe loss of vision. Among other causes, macular edema can happen because of a disease of the eye called Uveitis, and also after eye surgery. Treatment of macular edema remains a challenge as the condition may persist for several months and may lead to irreversible changes in the eye and poor vision. In the LEOPARD study the investigators wish to see how safe is the study drug (OCS-01) and how well it works, in resolving the fluid collection in the eye in patients with Uveitis or in patients who have had eye surgery. Participants will undergo detailed eye exam, and record their eye and medical history to see what their disease status is and if they can be included in the study based on the study criteria. If included, they will take the study drug OCS-01 in different doses for 24 weeks. During the study period, they will have regular eye exams to ensure their safety and to assess the usefulness of the study drug.

Purpose: Study the effect of nepafenac ophthalmic suspension 0.1% to prevent post-operative cystoid macular edema following uncomplicated cataract surgery Participants: Patients having cataract surgery at UNC who meet eligibility criteria Procedures (methods): Patients will have pre and post-operative vision measured and optical coherence tomography (OCT) testing, also cataract density and intraoperative phacoemulsification parameters including ultrasound power and ultrasound time will be measured. Patients will be randomized into two groups. Group 1 will be treated with standard post-operative cataract management. Group 2 will be treated with standard post-operative cataract management plus topical nepafenac for one month. Post-operative macular thickness will be studied by analyzing the visual acuity and OCT measurements at two months post surgery.
Cystoid Macular Edema
Cystoid macular edema (CME) is the most common cause of suboptimal post-operative visual acuity in uncomplicated cataract extractions. Over two million cataract extractions are performed each year, with a reported incidence ranging from 1.5 to 6.9%, resulting in an estimated 20,000-130,000 new cases of CME annually. Clinical CME historically was associated with visual acuity of 20/40 or worse with fluorescein angiographic evidence of macular edema in a classic petaloid pattern. Angiographic CME physiologically signals an inflammatory process causing distortion of the outer plexiform layer, which if not resolved quickly could result in non-repairable visual loss. Topical, periocular, or intravitreal corticosteroids, despite their associated side effects, are the mainstay for pharmacologic treatment for patients with CME. Their efficacy has never been demonstrated in a randomized, controlled and blinded study. This is an open-label, Phase II study of intravitreally administered ranibizumab in subjects with cystoid macular edema secondary to non-ischemic retinopathy, as seen following cataract surgery with intraocular lens implantation.
Cystoid Macular Edema
This research is being conducted to look at the effects of an intraocular drug (pegaptanib, also called Macugen) for the treatment of swelling in the retina (the light sensitive tissue in the back of the eye) that often occurs following cataract surgery in patients with diabetic eye disease. Swelling in the retina can lead to blurry vision, and Macugen may reduce this swelling. Eyedrops that decrease inflammation also may help to stop some of the swelling. We are testing this drug (pegaptanib) to see if it can decrease swelling in the retina and improve vision in patients with diabetes who are having cataract surgery.
Cystoid Macular Edema
This study will evaluate whether vitamin E can help treat swelling of the macular area of the retina (the back part of the eye) associated with uveitis (inflammatory eye disease). The macula is responsible for sharp vision; swelling in this area is one cause of vision loss in uveitis patients. Macular swelling is also associated with eye problems related to diabetes. In these patients, the swelling is thought to be caused by a substance called vascular endothelial growth factor, or VEGF. High doses of vitamin E have been used to treat these eye problems in diabetics. This study is a first step to find out if vitamin E will help reduce the retinal swelling in uveitis, which may also be caused by VEGF. Patients 9 years of age and older with macular edema associated with uveitis may be eligible for this study. Candidates will be screened with the following tests and procedures: * Medical history and physical examination. This includes measurement of vital signs (blood pressure, pulse, temperature and breathing rate) and examination of the head and neck, heart, lungs, abdomen, arms and legs. * Eye examination. This includes measurement of visual acuity using a vision chart, measurement of eye pressure and examination of the pupils and eye movements. The pupils will be dilated with drops to permit examination of the back of the eye. * Fluorescein angiography. This test uses a yellow dye (fluorescein) to take photos of the retina. The fluorescein is injected into an arm vein and travels to the blood vessels in the eye. The camera flashes a blue light into the eye and takes pictures of the retina. The pictures show if the dye has leaked from the blood vessels into the retina. * Stereoscopic color fundus photography. These are photographs of the back of the eye, taken after the pupils have been dilated with drops. * Optical coherence tomography. This test measures the macular swelling. It is used to determine if the swelling is getting worse, better or staying the same. * Blood tests. About a tablespoon of blood is drawn to measure inflammation and cell counts and side effects of treatment. * Pregnancy test. All women of child-bearing potential are tested for pregnancy. Participants will be randomly assigned to daily treatment with oral high-dose vitamin E (1600 units) or placebo (a pill with no active ingredient) for 4 months. They will be examined at 2 months and 4 months with the same tests performed for screening and will return for a final clinic visit 1 month after treatment has ended.
