Evaluation of Optic Disc Drusen Using Modern Imaging Paraclinical Methods.

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).

[Therapeutic management of a kissing nevus of the eyelid].

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.

Surgical excision of eyelid tumors and subsequent ophthalmoplastic reconstruction.

In recent years new modern therapeutic concepts have been developed in the treatment of malignant eyelid tumors; however, surgical restoration remains an important component of the therapeutic options addressed, which include microsurgical tumor excision into healthy tissue and subsequent coverage of the defects. 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.

[Complications of anophthalmic orbits-Treatment and aftercare].

The possible complications of anophthalmic eye sockets can occur due to many different pathomechanisms. A differentiation is made between allergic, infectious, inflammatory or mechanical causes. This article gives an overview on the different etiologies of socket complications with their pathophysiology and treatment options.

Reproducibility of Three-Dimensional Volumetric Measurement of Periocular Tumor Models.

Introduction: In this study, we measured the volume of customized tumor models in the periocular area using three-dimensional (3D) stereophotogrammetry and evaluated the reproducibility of these measurements.

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.

The role of the lateral tarsal strip procedure in modern ophthalmic plastic surgery-A review.

Introduction: The lateral tarsal strip is one of the basic surgical techniques in ophthalmic plastic surgery. It is used in many indications, predominantly in ectropion repair. Even though there are alternatives, it is probably one of the most popular techniques in ophthalmic plastic surgery.

EFFECT OF BASELINE CENTRAL RETINAL THICKNESS ON THE RESULTS OF TREATMENT OF DIABETIC MACULAR EDEMA WITH AFLIBERCEPT: REAL-LIFE EVIDENCE IN THE CZECH REPUBLIC.

Aim: Presentation of the 1-year results of aflibercept treatment in patients suffering from diabetic macular edema (DME) and comparison of the response to treatment of patients with different baseline central retinal thickness (CRT).

Methods: This was a multicentre, retrospective observational study of a series of cases. Patients with DME were treated in a fixed regimen (5 injections at 1-monthly intervals and then injections at 2-monthly intervals).

Post-enucleation socket syndrome-a novel pathophysiological definition.

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.

Ocular Involvement in COVID-19: Conjunctivitis and More.

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.

Cis Selective RCM Study to the 14-Membered Cyclic Subunit of Bielschowskysin.

A concise, ()-selective ring-closing metathesis (RCM) route to the 14-membered carbocycle of bielschowskysin is detailed using naturally occurring chiral starting materials. 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.

Changes in tear film osmolarity after 25G+ PPV.

Background: The aim of our study was to assess changes of tear film osmolarity after micro-incision 25G+ pars plana vitrectomy (PPV) in a prospective study.

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).

TRAUMA IN OCULOPLASTIC SURGERY A REVIEW.

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.

[Surgical resection with ophthalmoplastic reconstruction : Gold standard in periocular basal cell carcinoma].

The gold standard for the treatment of periocular basal cell carcinoma is surgical resection followed by ophthalmoplastic reconstruction. 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.

Xerosis in Patient with Vitamin A Deficiency - a Case Report.

Xerosis is a corneal and ocular surface disease caused by vitamin A deficiency. It is a rare disease in developed countries, but in third world countries it is a common cause of blindness. We describe a typical xerosis in patient with vitamin A deficiency and long-term malnutrition and alcoholism in our case.

[Cheek-midface lift for revision following failed excessive lower eyelid blepharoplasty].

Iatrogenic ectropion with sagging of the lower eyelid after failed excessive lower eyelid blepharoplasty is a severe complication in aesthetic surgery. Traditionally, free skin grafting is the method of choice for correction. This overview presents the cheek-midface lift as a useful and powerful method for the correction of ectropion following excessive lower eyelid blepharoplasty.
