HPI: BL is a 57-year-old right-handed female with an eight- month history of visual difficulties in her left eye. She underwent left-sided cataract surgery with lens replacement, but continued to have deterioration of her visual acuity, with complaints of blurriness in the left eye. She also complains of occasional diplopia. A recent ophthalmologic examination revealed exophthalmos.
Question: What is exophthalmos? |
|
Definition
| Answer: The eyeball bulges out. |
|
|
Term
| What does the low acuity in the left eye tell us about the optic nerve? |
|
Definition
| The pupils constrict to light, so the oculomotor nerves are intact bilaterally. (Besides controlling some movements of the eyes, the oculomotor nerve is responsible for pupillary constriction.) |
|
|
Term
| Diplopia on left lateral gaze suggests?. Together with the exophthalmos? |
|
Definition
| an issue with the abducens nerve.. Together with the exophthalmos, the symptoms suggest a mass posterior to the orbit. |
