Cystoid Macular Oedema
Cystoid Macular Oedema (CME) is a painless eye condition that affects the macula. It occurs when tiny cyst-like pockets of fluid build up within the macula, causing it to swell. This swelling leads to distorted or blurry central vision. People with CME may also notice dim or darkened vision, colour changes, or increased light sensitivity.
Symptoms and Risk Factors
The most common symptom of cystoid macular oedema is blurred or distorted central vision. Many patients notice straight lines appearing wavy or have difficulty reading fine print. Colours may appear dull, and some people experience increased sensitivity to light. Vision changes may develop gradually or suddenly, depending on the cause.
CME develops when damaged retinal blood vessels leak fluid into the macula. It is commonly associated with diabetic retinopathy, inflammation inside the eye (uveitis), or complications following cataract surgery.
How Cystoid Macular Oedema Is Diagnosed
Diagnosis of cystoid macular oedema involves a comprehensive eye examination and detailed retinal imaging. Optical Coherence Tomography is commonly used to create cross-sectional images of the retina and measure macular swelling. Fluorescein angiography may also be performed to identify leaking blood vessels. These tests allow ophthalmologists to confirm the diagnosis and monitor response to treatment.
Treatment Options for Cystoid Macular Oedema
Treatment depends on the underlying cause and may include anti-inflammatory eye drops, injections into the eye, laser therapy to seal leaking vessels, or vitrectomy surgery to remove scar tissue. With appropriate treatment, many patients experience gradual improvement in vision over several months.
Cystoid Macular Oedema Frequently Asked Questions
Is cystoid macular oedema permanent?
CME is not always permanent. Many cases improve with treatment, especially when addressed early.
Can cystoid macular oedema resolve on its own?
Some mild cases may improve, but most require medical treatment to prevent long-term vision damage.
Is cystoid macular oedema painful?
No, CME is usually painless, which is why vision changes should not be ignored.
How long does treatment for CME take?
Treatment length varies depending on the cause and response, but improvement often occurs over several months.
