History of Present Illness (HPI)
An 80 year old male presents to the primary care clinic for annual physical. He complains of worsening of his vision over the last year and notes sometimes he bumps into objects on his side as he doesn’t see them. He had cataract surgery 3 years ago after which he felt his vision improved but now it has gotten worse again. His last eye exam was over 1 year ago. He states he was prescribed “eye drops” but ran out of them a few months ago. Of note, his mother became blind in her 60s but he is unsure why.
He places the following empty eye drop bottles on the exam table and requests a refill.
