Case Report: - and Mutations in an Aggressive Case of Relapsing Uveal Ring Melanoma.

The molecular mechanisms for uveal ring melanoma are still unclear until today. In this case report, we describe a patient with a malignant uveal melanoma with exudative retinal detachment that had been treated with plaque brachytherapy, resulting in successful tumor regression. After 1 year, a ring-shaped recurrence with extraocular extension appeared, and the eye required enucleation.

[Retinal tumors in adults: Part 2 nonvascular tumors of retina and retinal pigment epithelium].

Retinal tumors are a heterogeneous group of congenital and acquired lesions. In the second part of the article retinocytic and glial cell tumors of the retina, tumors of the retinal pigment epithelium, malignant tumors, such as lymphomas and metastases are presented. In benign and malignant tumors visual symptoms, such as exudative retinal detachment occur, which often lead to irreversible visual impairments.

[Retinal tumors in adults - Part 1: vascular tumors of the retina].

Retinal tumors are a heterogeneous group of congenital and acquired lesions. In this review series the important retinal tumors are discussed and presented in two articles. In the first part of the article the most important vascular tumors of the retina are presented.

Evaluating diurnal changes in choroidal sublayer perfusion using optical coherence tomography angiography.

Purpose: To investigate diurnal changes of choroidal sublayer perfusion in normal eyes and to identify influencing factors using optical coherence tomography angiography (OCTA).

Methods: A prospective study was conducted on healthy volunteers, each of whom underwent repeated measurements of subfoveal choroidal thickness (SFCT) via enhanced depth imaging (EDI) optical coherence tomography (OCT) as well as perfusion of choroidal vascular sublayers using OCTA at 7 a.m.
