Conjunctival melanocytic naevus: Diagnostic value of anterior segment optical coherence tomography and ultrasound biomicroscopy.

Purpose: Conjunctival naevi are the most frequently diagnosed primary melanocytic lesions of the conjunctiva. The clinical manifestations are greatly variable which may result in diagnostic difficulties and differential diagnostic confusions. Therefore aims of the present study were: 1) to assess the morphologic features of conjunctival naevi; 2) to delineate the anterior segment optical coherence tomography (AS-OCT) characteristics of these lesions; 3) to compare AS-OCT and ultrasound biomicroscopy (UBM) as diagnostic tools in these alterations and 4) to correlate histological results with the AS-OCT pictures in case of surgically excised naevi.

Giant Conjunctival Nevus in a 12-Year-Old Child.

We describe a case of a giant conjunctival nevus presented in a 12-year-old girl with suspicious clinicomorphological appearance. The lesion was noticed by the parents at the age of 3 years as a "fleshy spot" on the bulbar conjunctiva. The lesion remained unchanged until approx.

Description of five dirofilariasis cases in South Hungary and review epidemiology of this disease for the country.

Background: Dirofilariasis is an emerging zoonosis (supported by climate change) in Central Europe. Human infections are usually caused by Dirofilaria repens and Dirofilaria immitis with mediation of mosquito vectors. Aims of this publication were to report our dirofilariasis cases, and to summarize Hungarian epidemiological data by reviewing literature.

Role of ultrasound biomicroscopy in diagnosis and treatment of Terrien disease.

Purpose: Terrien disease is a rare form of peripheral corneal degeneration characterized by vascularization, opacification, lipid deposition, and corneal thinning. In this study, a high-frequency ultrasound biomicroscope (UBM) was used to detect the morphologic changes before and after surgery and to determine the stages of this disease.

Methods: Two patients with Terrien disease were examined by UBM, corneal topography, and a keratometer before and after surgery (full-thickness keratectomy).
