Background: Chronic progressive external ophthalmoplegia (CPEO) belongs to the group of mitochondrial encephalomyopathies. Anaesthesia for patients with CPEO may be associated with an increased risk due to known drug effects on mitochondrial metabolism. Therefore, the aim of this analysis was to evaluate anaesthesiological concepts in patients with CPEO requiring ophthalmic surgery.

Purpose: Aims to provide an overview of the contemporary epidemiology of malignant orbital tumors by analyzing population-based incidence patterns across various regions worldwide.

Methods: In this article, we retrieved orbital malignancy data from the MEDLINE database and analyzed the incidence and prevalence of orbital malignancies worldwide. We performed the literature search by searching on the Mesh terms for malignant orbital tumors ("orbital", "tumor", "lymphoma", "malignant", "cancer", "incidence", and "epidemiology").

Article Synopsis
  • This study focused on validating the FACE-Q eye module scales in German for patients undergoing blepharoplasty, a cosmetic eye surgery.
  • Researchers translated and tested these scales on different groups, including those who had the surgery and control subjects, with a total of 193 participants.
  • The findings indicated that the German FACE-Q eye module demonstrated strong reliability and validity, effectively measuring satisfaction and psychological impact post-surgery.

Objective: To quantitatively assess the periocular asymmetry and investigate its sex and age-related differences in a Caucasian population using three-dimensional (3D) stereophotogrammetry.

Method: Standardized 3D photos of the periocular region of 301 Caucasians were taken using the VECTRA M3 3D Imaging System. Standardized landmarks were positioned, and data measurements in the periocular region were obtained from these images using VAM software and assessed using intraclass correlation coefficients (ICC) for reliability.

Purpose: To assess the intraday repeatability of macular architecture measurements in glaucomatous and non-glaucomatous patients using spectral-domain optical coherence tomography (SD-OCT) and to evaluate the independence from intraindividual intraocular pressure (IOP) fluctuations.

Methods: In this single-center, time-point comparison study, 88 eyes with glaucoma, 53 eyes with ocular hypertension (OHT), and 253 healthy eyes underwent two standardized SD-OCT and intraocular pressure (IOP) measurements on the same day with a 5-h time gap. Bland-Altman plots, intraclass correlation coefficients (ICC), and random-effects model were used to analyze repeatability of entire retinal thickness, retinal nerve fiber layer, ganglion cell layer, inner plexiform layer, and inner nuclear layer measurements.

Purpose: To explore the role of ultraviolet radiation (UVR) in the occurrence and development of various ocular malignancies.

Methods: In this article, we retrieved ocular malignancy data from the Global Cancer Observatory (GCO) and performed correlation analysis with the global UV index and sunshine duration. We searched for associated studies using the following databases: Embase, Pubmed, Cochrane Library, and Google Scholar.

Orbital and periocular metastatic tumors used to be considered very rare; however, with the constant updating of drugs and detection methods for cancer treatment, new chemotherapies and radiation treatments are being used. The life expectancy of cancer patients has become longer and periocular metastases are becoming easier to detect. Our knowledge of this rare disease of metastases also needs to be updated.

Enucleation of an eye is the most invasive procedure in ophthalmologic surgery. It can be the result of various diseases (malignant/chronic/trauma/infection) and is nevertheless relatively rare, but leads to the loss of a strongly innervated neuronal organ. This study systematically evaluates postoperative pain levels following enucleation of the eye globe.

Article Synopsis
  • The periocular skin is highly susceptible to both benign and malignant tumors, with malignancies in this area being more aggressive and harder to treat compared to other skin regions.
  • Recent advancements in immunotherapy have enabled the immune system to effectively target and destroy cancer cells, particularly benefiting the treatment of periocular tumors.
  • The choice of treatment for periocular skin cancer should be individualized based on tumor type, size, and genetic factors, and may involve a combination of chemotherapy and immunotherapy options.

The use of laryngeal masks in the surgical treatment of infantile lacrimal duct stenosis is controversial due to the potential risk of aspiration. This study investigates airway procedures in children aged <6 years for surgery of lacrimal duct stenosis in a tertiary care university hospital. After institutional approval, airway procedures, duration of anesthesiological measures, and airway-related complications were retrospectively analyzed.

The aim of this case study was to investigate the effects of an 8-wk combined exercise intervention, consisting of visual-coordinative and high-intensity interval training (HIIT), on the physical and visuomotor-functional capacity, performance, and physiological profile of a moderately active 29-yr-old man diagnosed with choroidal melanoma of the left eye. Data were collected on three occasions: at the initial diagnosis (T0), after hospitalization and radiotherapy treatment (T1), and following the recovery through the exercise intervention (T2), spanning a total of 17 wk. The primary outcome variables consisted of visuomotor and functional tests (VFTs), cardiorespiratory fitness (CRF), and microvascular circulation measured via flicker light-induced dilation (FiD).

Background: Creating an appropriate treatment plan for patients with dermatochalasis requires careful investigation of the periocular region. Utilizing photographic documentation can assist physicians in conducting preoperative analysis and managing expectations regarding surgical outcomes.

Objectives: This study aimed to quantify the periocular characteristics of dermatochalasis patients using standardized 3D imaging and to compare age and sex-related changes in periocular features.

Viral conjunctivitis is one of the most common acute eye diseases. The fall and winter months are known to be the main season for viral infections which is also reflected in the ophthalmological outpatient clinics. Viral conjunctivitis is often accompanied by symptoms of the upper and lower respiratory tract, fever, chills, arthralgia or skin lesions.

Pain following eye surgery is often described as being relatively moderate; however, there are also procedures that lead to a pronounced pain experience. Particularly in pediatric patients, pain therapy is often insufficient due to a lack of knowledge and fear of complications. These individual and organizational deficits lead to unnecessary discomfort for children and parents.

Background: Although a portable 3-dimensional (3D) imaging system has been used for periocular measurement analysis, this system has yet to be tested and validated for periocular area and volume measurements.

Objectives: The aim of this study was to define the upper eyelid and upper eyelid fold region through a modified landmark strategy and validate a portable 3D imaging system for area and volume measurements in this periocular region.

Methods: Eighty-one healthy adult Caucasians underwent 3D facial imaging with the VECTRA M3 (static) and VECTRA H2 (portable) 3D imaging systems (Canfield Scientific, Inc.

Background: Three-dimensional (3D) surface imaging and morphometrics are becoming the preferred craniofacial surface imaging modality. However, as a unique advantage of 3D imaging, areal and volumetric measurements have been rarely conducted and validated for evaluating soft tissue change in the periocular region, especially the upper eyelids. Therefore, based on an existing periocular landmark identification strategy, we proposed a novel modified method to define a standardized upper eyelid region for areal and volumetric measurements and validate its reliability for future clinical application.
