Which symptom is NOT associated with corneal edema?

Severe light sensitivity, while it can be associated with various ocular conditions, is not a specific symptom tied to corneal edema. Corneal edema occurs when there is an accumulation of fluid in the cornea, leading to swelling and a variety of vision-related symptoms.

Smoky vision arises due to the clouding and distortion of the cornea as it swells, which disrupts light passage through the optical medium. Reduced contrast sensitivity often accompanies corneal edema as the clarity of visual detail diminishes due to the swelling and irregular surface of the cornea. Increased spectacle blur can also occur as the distorted cornea changes the way light enters the eye, leading to a less-than-sharp image.

In contrast, while light sensitivity (photophobia) can occur in a range of eye conditions, it isn't specifically a hallmark symptom of corneal edema. The symptoms associated with corneal edema primarily focus on vision distortion and clarity issues rather than sensitivity to light.
