[Changes of the conjunctival nervous fillets in diabetic patients].

Purpose: Our study suggested to reveal nervous fillets changes from conjunctiva structure in patients with diabetes.

Material And Method: We removed bulbar conjunctiva during cataract surgery on diabetic and non-diabetic patients from the same age group. The conjunctiva fragments were fixed in Lillie's solution, then studied by using optical microscopy with usual and histochemical stainings.

Results: Nervous fillets just like perinervium are better represented in younger diabetic patients without diabetic retinopathy or with early diabetic retinopathy and non-diabetic patients, too. In older patients and old diabetes, nervous fillets are much less in number with poor represented perinervium.

Conclusions: Significant changes of the conjunctiva nervous fillets were found in patients with long-term diabetes.
