A 76-year-old female with a history of well-controlled diabetes recently underwent uncomplicated phacoemulsification with a posterior chamber intraocular lens and complains of blurry vision. Best-corrected visual acuity (BCVA) is 20/60. Her fluorescein angiogram and OCT are provided in the image below
Which retinal layer accounts for the appearance of this patient’s vision loss?
|A.||Nerve fiber layer|
Answer: B) Outer plexiform
Explanation: The image shows a fluorescein angiogram of classic petalloid hyperfluorescence. The “petalloid” leakage pattern on IVFA is due the accumulation of serous fluid in the outer plexiform layer of the retina, which is seen on the spectral-domain OCT image.
