TAG
(M2.OP.5) A 75-year-old male with a history of hypertension presents to the ophthalmologist office after being referred by his primary care physician for blurry vision and difficulty driving at night. The patient reports a gradual blurring of vision in both eyes over the last 10 years. He states that he is retired and was not bothered by the blurriness but is now having difficulty driving at night due to glare from oncoming traffic. The patient denies any eye pain, flashes, floaters, tearing, redness, or periods of complete vision loss. A photo of the patient's eye viewed through a slit-lamp is shown (Figure A). A dilated fundus exam reveals a normal optic nerve and retina bilaterally. What is the cause of this patient's condition?
