Purpose: To analyze patients with optic disc drusen (ODD), with emphasis on modern diagnostics.
Materials And Methods: Research of the literature was conducted, together with a retrospective statistical analysis of patients with ODD. The group included individuals with ODD diagnosed using at least one of the following (ultrasound - USG, optical coherence tomography - OCT, fundus autofluorescence - FAF).
Congenital divided melanocytic nevi of the upper and lower eyelid are rare pigmented changes of the eyelids. These processes are also known as "kissing nevi," "panda nevi," and "split ocular nevi," and were first described by Fuchs in 1919. About 120 cases have been described in the literature so far.

An ophthalmic surgeon experienced in oculoplastic surgery is responsible for the recognition and evaluation of the existing alterations and planning a procedure together with the patient that meets the patient's expectations. The planning of surgery must always be individualized and fit the initial findings.

Methods: Five tumor models of different colors and sizes were placed in different periocular positions, and 3D facial images were obtained from 68 healthy adult volunteers. Subsequently, the volumes of the tumor models were measured, and the intra- and interrater reproducibility was assessed.

Background: The last definition of the post-enucleation socket syndrome (PESS) by Tyers and Collin-formulated almost 40 years ago in 1982-is predominantly based on the clinical characteristics and does not include the insights of newer studies into the pathophysiological mechanism of the PESS.
Methods: A systematic PubMed literature review regarding the pathophysiological mechanism of the PESS was performed, and results were comprised to give an overview of the current knowledge of the PESS including the exact pathophysiological mechanism.
Results: The primarily postulated pathophysiological mechanism of the PESS was the atrophy of orbital tissues, especially of fat, resulting in variable clinical findings.
Since the beginning of 2020, SARS-CoV-2, the pathogen of COVID-19, has led to a global pandemic that also affects ophthalmology. Ophthalmologists can be confronted at any time with potentially COVID-19 associated ocular symptoms or manifestations in patients and also become infected through close patient contact. Even without systemic infection, the ocular surface can come into direct contact with aerosols or liquids containing SARS-CoV-2 particles.

Unproductive RCM substrates were attributed to alkyne chelation of the ruthenium catalyst and steric disadvantages within the cembranoid precursors, which was eventually circumvented by using cyclic diol benzylidene protection involving a C8-quaternary carbinol center.

Methods: The group consisted of 21 patients (17 women, 4 men) with an average age of 70,52 years [48; 85]. All patients underwent 25G + PPV surgery due to a disorder of the vitreomacular interface (macular hole or epimacular membrane).
The aim of this article is to present the basics of traumatology in oculoplastic surgery and to review the literature about this topic. This review sums up the problematic of injuries of the eyelid, lacrimal system and orbit. The most important types of trauma, their treatment options, and the most common complications are described.

The highest priority in most cases is the complete histopathologically controlled tumor excision. The histopathological preparation can be carried out in two stages by rapid overnight embedding or intraoperatively by a rapid frozen section procedure.
