Retrobulbarly injecting nerve growth factor attenuates visual impairment in streptozotocin-induced diabetes rats.

Purpose: To explore whether retrobulbar administration of nerve growth factor (NGF) can restore visual function of streptozotocin-induced diabetes rats.

Methods: A high-sucrose/high-fat diet and single injection of streptozotocin (STZ) were used in modeling diabetes. During week 13-15 after STZ injection, diabetic rats were received retrobulbar βNGF injection.

[Analysis of misdiagnostic causes of Coats disease].

Objective: To analyze the clinical features and misdiagnostic causes of Coats disease.

Methods: The clinical data were retrospectively analyzed in 69 eyes of 68 patients with Coats disease.

Results: Misdiagnostic histories to a varying degree occurred in 11 of the 68 cases with a misdiagnosis rate of 16.
