Cystoid macular edema
Cystoid macular edema (CME) is a condition that affects the macula, the central part of the retina in the human eye. It is characterized by the accumulation of fluid in the macula, leading to swelling and visual distortion.
Causes[edit | edit source]
CME can be caused by a variety of conditions, including diabetic retinopathy, retinal vein occlusion, uveitis, and following cataract surgery. It can also occur as a result of certain medications, such as prostaglandin analogs used for glaucoma treatment.
Symptoms[edit | edit source]
The main symptom of CME is blurred or distorted central vision. This can affect activities such as reading, driving, and recognizing faces. Other symptoms can include decreased color perception and sensitivity to light.
Diagnosis[edit | edit source]
CME is diagnosed through a comprehensive eye examination. This may include a visual acuity test, a dilated eye exam, and imaging tests such as optical coherence tomography (OCT) and fluorescein angiography.
Treatment[edit | edit source]
Treatment for CME depends on the underlying cause. Options may include corticosteroid eye drops, nonsteroidal anti-inflammatory drugs (NSAIDs), or anti-vascular endothelial growth factor (anti-VEGF) injections. In some cases, laser therapy or vitrectomy surgery may be recommended.
Prognosis[edit | edit source]
The prognosis for CME varies depending on the underlying cause and the individual's response to treatment. In some cases, vision may improve with treatment, while in others, vision loss may be permanent.
