Transient visual disturbances such as scintillations, often without a structural ocular abnormality, characterize which condition?

• A. Ocular Migraines
• B. Hyphema
• C. Corneal Ulcer
• D. Premature Baby

Answer: (A)

The main idea being tested is recognizing transient, aura-like visual phenomena that occur without any detectable eye disease. The description of scintillations or zig-zag, flickering lights that move across the visual field, with a normal-appearing eye on exam, is classic for a migraine aura affecting vision—often called an ocular migraine. These visual disturbances arise from transient, reversible changes in cortical activity (occipital lobe), and they can occur with or without a subsequent headache. In contrast, a hyphema would present with visible blood in the front part of the eye and typically cause pain and redness; a corneal ulcer would cause pain, tearing, photophobia, and a corneal defect on examination; and a premature baby is not a diagnosis that explains transient scintillations. So the scenario best fits ocular migraine.
