title: Non-diabetic retinal abnormalities in chronic pancreatitis.
abstract: To determine whether retinal abnormalities occur in patients with chronic pancreatitis, ophthalmoscopic and retinal-function evaluation was performed in 28 patients with chronic pancreatitis and 19 healthy subjects. The final threshold of dark adaptation was significantly increased 40 per cent (P less than 0.001) in patients with pancreatitis, whether or not they had steatorrhea. Patients with steatorrhea had a significant decrease of about 42 per cent (P less than 0.001) in the b-wave of the electroretinogram, a measure of both rod and cone function. Seven of the 28 patients complained of difficulty with hight vision; six of these seven had morphologic lesions on ophthalmoscopic examination, confirmed by fluorescein angiography. No correlation was found between any of the retinal abnormalities and the serum vitamin A or zinc levels or glucose tolerance. Non-diabetic retinal lesions and retinal-function abnormalities are common in patients with chronic pancreatitis, even in the absence of steatorrhea.
