β-Adrenoreceptors as Therapeutic Targets for Ocular Tumors and Other Eye Diseases-Historical Aspects and Nowadays Understanding

β-adrenoreceptors (ARs) are members of the superfamily of G-protein-coupled receptors (GPCRs), and are activated by catecholamines, such as epinephrine and norepinephrine. Three subtypes of β-ARs (β₁, β₂, and β₃) have been identified with different distributions among ocular tissues. Importantly, β-ARs are an established target in the treatment of glaucoma. Moreover, β-adrenergic signaling has been associated with the development and progression of various tumor types. Hence, β-ARs are a potential therapeutic target for ocular neoplasms, such as ocular hemangioma and uveal melanoma. This review aims to discuss the expression and function of individual β-AR subtypes in ocular structures, as well as their role in the treatment of ocular diseases, including ocular tumors.

Conjunctival granulomatous capillary haemangioma in children: case report and review of the literature

Background

Granulomatous capillary haemangioma refers to a benign vascular tumour that commonly affects the skin, with occasional involvement of the mucosa. Reports of conjunctival granulomatous capillary haemangioma in children are uncommon. In this article, we present a case of granulomatous capillary haemangioma and a brief review of the relevant literature.

Case presentation

An 11-year-old girl presented with a conjunctival mass. An excision of the entire lesion was performed. Histopathology showed a granulomatous capillary haemangioma.

Conclusions

The clinical manifestations of granulomatous capillary haemangioma lack specificity; pathological characteristics and immunohistochemistry are the main basis for diagnosis. We retrospectively analysed the diagnosis and treatment of a patient with conjunctival granulomatous capillary haemangioma to deepen the understanding and facilitate the diagnosis and treatment of this disease.
