What are common treatments for macular edema?

There are no currently accepted guidelines for treating macular edema. Nevertheless, most physicians are in favor of using anti-VEGF agents, corticosteroid injections, and laser photocoagulation under strict clinical trial protocols.

What are the signs of macular edema?

Macular edema may cause pain or visual impairment in many patients suffering from central retinal artery occlusion. It may also cause blurred vision due to swelling of the optic disc and the retina. Often macular edema is caused by a number of ocular and systemic conditions and treatments that cause retinal vascular obstruction, including diabetes, hypertension, and hyperhomocysteinemia. In this article you'll learn more about macular edema by reading on some common signs of macular edema.

How many people get macular edema a year in the United States?

The U.S. estimated 0.9 new cases of MAC from all causes per 10,000 individuals a year, and 0.3 cases/10,000 individuals per year from myopia. This is a similar estimate to that reported by the Joint National Committee on Vision and Optometry for the period of 2002 to 2005 (0.8 and 0.3 cases/10,000 individuals per year. It appears that the incidence of MAC and its related complications may be rising.

What is macular edema?

In a recent study, findings the prevalence of ME in patients with ocular hypertension and glaucoma was similar. Moreover the prevalence was similar when patients were subdivided by age and of Hispanic and non-Hispanic ethnicity. In a recent study, findings also indicated that ME was more common in women than in men.

Anonymous Patient Answer

Can macular edema be cured?

The data show that, based on best-available and recent research, the risk of developing a new occurrence of ME following successful resolution has been low, and, therefore, symptomatic interventions of macular edema are not warranted for those with a history of ME who are successfully treated for ME. In addition, while our study did not find any association between ME and long-term change in visual acuity, current evidence does not support the use of therapy for macular edema in improving vision after it has already occurred.

Anonymous Patient Answer

What causes macular edema?

As the prevalence of macular edema increases in countries such as the US and in elderly patients, a clearer explanation of how macular edema develops in the eye is needed. The mechanism may be related to the development of cataracts, which are more common in aged subjects and in those with glaucoma. In addition, vascular disease plays an important role in the pathogenesis of macular edema.

Anonymous Patient Answer

Have there been any new discoveries for treating macular edema?

The recent research confirms the positive role of anti-VEGF therapies in the treatment of neovascular AMD. These therapies show an improvement of visual acuity even without a reduction in CNV. Nevertheless, these therapies have potential side effects and need to be evaluated for their long-term health consequences. The research also suggests that [triamcinolone acetonide and photodynamic therapy are useful therapies for preventing the visual loss in patients with exudative neovascular AMD] despite their risks related to the treatment such as blindness.

Anonymous Patient Answer

Have there been other clinical trials involving treatment?

Most people with ME have been treated in clinical trials involving treatment, for various indications. Some of them have been ineffective. The experience from other trials of treatment has been important and have improved treatment for most patients. The authors support the ongoing use of clinical trials so that all patients with ME will have the best chance of getting the best treatment possible.

What is the latest research for macular edema?

As the treatments for macular edema become more advanced, better and safer, our knowledge of the precise causes of macular edema is becoming increasingly essential for patient care.

Anonymous Patient Answer

Is treatment safe for people?

Based on the results of this study, it appears that treatment is safe and effective for patients up to 2 months following treatment, as the rate of complications is similar to the rate in the general population. Further research is warranted to evaluate long-term safety data for longer duration of follow-up.

What does treatment usually treat?

A [fundus floaters' syndrome]] seems to be treated first by conventional treatment, since there are many treatment options at our institution. However, if the floaters' syndrome does not go away under treatment, then it becomes necessary to conduct a definitive treatment or procedure. The power of [Power(1/1.15)] and the clinical trials make it easy to find treatments for floaters. As of 2010, there had been no floaters who responded favorably to only conventional treatment without surgery, and there are a few treatments to watch out for. Visit [Power(1/1.15)]; for more information.

What is the primary cause of macular edema?

Primary macular edema could be caused by multiple pathologic processes. However, the majority of eyes with primary macular edema have a primary etiology unrelated to ischemia. Primary macular edema should be considered in all patients with a sudden onset of visual loss. The most common causes of primary macular edema are neovascular age-related macular degeneration, nonresponsive or chronic macular edema, uveitis, trauma, diabetes, and retinopathy of prematurity. Secondary macular edema can also be due to systemic disorders and disorders of the ocular anatomy.
