Non-diabetic retinal abnormalities in chronic pancreatitis

Area of Science:

• Ophthalmology
• Gastroenterology
• Retinal Function

Background:

• Chronic pancreatitis is a complex condition with systemic implications.
• Ocular manifestations in chronic pancreatitis are not well-documented.

Purpose of the Study:

• To investigate the prevalence and nature of retinal abnormalities in patients with chronic pancreatitis.
• To assess retinal function using ophthalmoscopy and electroretinography.

Main Methods:

• Evaluated 28 chronic pancreatitis patients and 19 healthy controls.
• Performed ophthalmoscopic examinations and retinal-function tests, including dark adaptation and electroretinography (ERG).
• Correlated findings with steatorrhea, vitamin A, zinc levels, and glucose tolerance.

Main Results:

• Patients with chronic pancreatitis showed significantly impaired dark adaptation (40% increase).
• Those with steatorrhea had a significant ERG b-wave decrease (42%), indicating compromised rod and cone function.
• Seven patients reported night vision difficulties, with six showing ophthalmoscopic lesions confirmed by angiography.

Conclusions:

• Retinal abnormalities and function deficits are common in chronic pancreatitis patients.
• These ocular findings can occur independently of steatorrhea.
• No correlation was observed with serum vitamin A, zinc, or glucose tolerance levels.
