Berlin's edema is another term for which condition?

• A. Retinal Detachment
• B. Commotio Retinae
• C. Conjunctival Hemorrhage
• D. Traumatic Optic Neuropathy

Answer: (B)

Berlin's edema is commotio retinae, a retinal whitening that occurs after blunt trauma to the eye. This happens when the outer retina, especially the photoreceptor outer segments and nearby retinal pigment epithelium, becomes edematous from the trauma. The whitening is most noticeable in the posterior pole, and if the macula is involved, vision can drop temporarily. A classic sign is a cherry-red spot at the fovea, where the underlying choroidal color shows through because the surrounding retina has become pale. Most cases improve as the edema resolves over weeks to months, though vision can be permanently affected if the fovea is damaged. This condition is distinct from retinal detachment, conjunctival hemorrhage, or traumatic optic neuropathy, which involve different structures and presentations.
