title: [Local microcirculation in persons with primary pterygium, as evidenced by fluorescein-angiographic studies].
abstract: Fluorescence angiography was used to study local microcirculation in 20 patients (9 females and 11 males) aged 18 to 48 years who had primary pterygium. All pterygiums were divided into unprogressive (10 patients, 10 eyes) and progressive (10 patients, 10 eyes). The revealed pattern of the microangioarchitectonics of pterygium suggests that there is an independent isolated microvascular system that comprises a system of posterior conjunctival vessels, relatively large arterial trunks, and a developed newly formed vasculature. Unprogressive pterygium is characterized by a slightly developed neovasculature in the tissue of pterygium, in its head in particular, while the progressive form is marked by a rich neovasculature with pronounced extravasal fluorescence.
