Retinal swelling

Retinal swelling, also known as macular edema, occurs when fluid accumulates in the retina, particularly in the macula—the central part responsible for sharp vision. This can result from diabetes (diabetic macular edema), vein occlusions, or inflammatory conditions. Symptoms include blurry or distorted central vision, difficulty reading, and noticing colors less vividly. Detecting retinal swelling involves optical coherence tomography (OCT) or fluorescein angiography. Treatment may involve medications, laser therapy, or injections to reduce fluid and restore normal vision.
