Evaluation of parafoveal and peripapillary vascular densities using optical coherence tomography angiography in children with thalassemia major.

Background: Thalassemia major (TM) is an inherited anaemia caused by faulty haemoglobin synthesis. Reducing serum iron levels using iron chelating agents is an important step in the treatment of TM, and the effects on the eye of both the disease and these agents can be determined by regular eye examination.

Objectives: We evaluated macular and optic nerve vascular densities in children with TM and compared the results with healthy controls using optical coherence tomography angiography (OCTA).

Quantitative Evaluation of Pupil Responses in Patients with Prolactinomas Being Treated with Dopamine Agonists.

The aim of this study was to determine whether the dopamine agonist (DA) drug cabergoline used in the treatment of prolactinoma causes autonomic dysfunction by measuring static and dynamic pupillary responses. The study included 25 eyes from 25 patients who were receiving DA for the treatment of prolactinoma and 25 eyes from 25 healthy individuals. Static and dynamic pupillary responses were measured by automatic quantitative pupillometry.

Purpose: We aimed to determine whether there are retinal microvascular changes in patients with celiac disease (CD).

Methods: A total of 30 patients with CD (group 1) and 30 healthy controls (group 2) were included in this study. AngioVue optical coherence tomography angiography (OCTA) device was used to evaluate the retinal microvascular structure.

Evaluation of parafoveal vascular density using optical coherence tomography angiography in patients with central serous chorioretinopathy.

Using optical coherence tomography angiography (OCTA), we sought to evaluate parafoveal vascular density (VD) in patients with central serous chorioretinopathy (CSCR). Our study included 43 patients with a diagnosis of CSCR and 40 healthy controls. Ophthalmologic examination findings and OCTA measurements of the participants were retrospectively analysed.
