Cystoid Macular Edema FAQs
What is cystoid macular edema?
Cystoid macular edema is a common condition that involves swelling in the macula, the center part of the vision that allows objects to be seen with great detail. This swelling occurs as fluid builds up in the layers of the macula, gradually blurring vision.
What causes cystoid macular edema?
Most cases of cystoid macular edema develop in patients who have had recent eye surgery, such as cataract surgery, as well as patients with diabetic retinopathy, uveitis and retinal vascular disease. Because of the inflammation caused by cataract surgery, the blood vessels in the center part of the retina may become inflamed and start to leak. As leakage occurs, the tissues begin to swell and affect vision.
How does cystoid macular edema affect vision?
While this condition does not cause any pain for most patients, it causes increasingly blurry vision, especially when reading. This usually occurs about two to eight weeks after cataract surgery. Vision may also be distorted, with straight lines appearing wavy, and may be tinted pink as well. Peripheral vision is usually not affected by this condition.
How is cystoid macular edema diagnosed?
When symptoms of cystoid macular edema are present, the doctor may perform a series of diagnostic tests to confirm diagnosis. The tests may include:
- Fluorescein angiogram
- Optical coherence tomography
- Dilated eye examination
While this disease can be detected by the doctor before symptoms are present, it is usually very difficult to detect.
What are the treatment options for cystoid macular edema?
Treatment for cystoid macular edema will vary depending on the severity and cause of the condition and the individual patient. Treatment may involve:
- Ocular eye drops
- Ocular injections
- Anti-inflammatory medication
- Diuretics
- Vitrectomy surgery
Most patients experience significant improvements to their vision after one or more of these treatment options, with full recovery taking several months.
