The chorioretinal junction comprises the retinal pigment epithelium, Bruch's membrane (BM), and adjacent choroidal capillaries. Its significance lies in its ability to support the retina mechanically and metabolically. The aim of this cross-sectional study was to record the senescent changes affecting all the constituents of the chorioretinal junction in 40 histological specimens across the whole spectrum of the adult age range. This study included light microscopy, with hematoxylin and eosin and PAS stains, and fluorescent microscopy...

Purpose: To identify the spatial distribution of exudative features of choroidal neovascularization in neovascular age-related macular degeneration (nAMD) based on the localization of intraretinal cystoid fluid (IRC), subretinal fluid (SRF), and pigment-epithelial detachment (PED). Methods: This retrospective cross-sectional study included spectral-domain optical coherence tomography volume scans (6 × 6 mm) of 1341 patients with treatment-naïve nAMD. IRC, SRF, and PED were detected on a per-voxel basis using fully automated segmentation algorithms...

Purpose: Presently, 52 independent nuclear single nucleotide polymorphisms (nSNPs) have been associated with age-related macular degeneration (AMD) but their effects do not explain all its variance. Genetic interactions between the nuclear and mitochondrial (mt) genome may unearth additional genetic loci previously unassociated with AMD risk. Methods: Joint effects of nSNPs and selected mtSNPs were analyzed by two degree of freedom (2df) joint tests of association in the International AMD Genomics Consortium (IAMDGC) dataset (17,832 controls and 16,144 advanced AMD cases of European ancestry)...

INTRODUCTION: In 2001 a survey among retinal surgeons regarding the treatment of rhegmatogenous retinal detachment either with scleral buckling methods or primary vitrectomy was performed. Due to the technical progress of vitrectomy and observational systems, it seemed appropriate to renew and update this survey supplemented with current aspects. METHODS: In this study 78 vitreoretinal surgeons from German-speaking countries were surveyed via an anonymous online questionnaire on their treatment decisions for defined retinal detachment constellations...

REVIEW
H Hoerauf, B Kirchhof
Elective surgery of the vitreoretinal interface is currently the most common reason for vitrectomy in Germany. The evaluation and correct interpretation of spectral domain optical coherence tomography (SD-OCT) images is of great importance but the indications for vitrectomy in macular surgery should be based more on patient symptoms and not only the OCT findings. Watchful waiting is highlighted as an alternative therapeutic option in individual patients. This article addresses a number of aspects and discrepancies between findings and patients' level of suffering based on binocular symptoms...

BACKGROUND: Uveitis is the most common extra-articular manifestation of juvenile idiopathic arthritis (JIA). It occurs, according to German registry data, in around 12% of JIA patients and can lead to a loss of vision, especially in cases of delayed diagnosis and/or inadequate therapy. OBJECTIVE: A review of current aspects of diagnosis and therapy was carried out. MATERIAL AND METHODS: This is a review article of the current literature. RESULTS: The risk of uveitis is significantly elevated in patients with an oligoarticular course of JIA, ANA positivity and young age at onset of JIA...

PURPOSE: To evaluate the outcome of 23 G PPV and ILM peeling with 14% C3F8 compared with silicone oil tamponade in cases of TMHs without spontaneous closure. METHODS: A retrospective comparative study included 33 eyes with TMHs; 7 eyes healed spontaneously, and the remaining 26 eyes have been treated with PPV and ILM peeling. Silicone oil was used as a tamponade for children or adults who refused to adopt face-down position (10 cases). In all other cases (16 cases), 14% C3F8 was used...

A 78-year-old immunocompetent man presented with a 3-month history of painless decreased vision and panuveitis with a macular lesion presumed to be due to endogenous endophthalmitis. He had been treated with systemic, intravenous, and intravitreal antibiotics and antifungal agents as well as intravitreal steroids. A culture from a prior vitrectomy had grown a single colony of Aspergillus thought to be a contaminant. The macular lesion enlarged and caused a tractional retinal detachment. The patient underwent surgery including resection of what appeared to be an invasive retinal aspergilloma, from which polymerase chain reaction and histopathology confirmed Aspergillus fumigatus...

BACKGROUND AND OBJECTIVE: To describe morphologic characteristics, surgical outcomes, postoperative preferred retinal loci (PRL), and fixation stability of epiretinal membranes (ERMs) in young patients. PATIENTS AND METHODS: This retrospective study analyzed 43 eyes of 41 young patients (age range: 0.8 years to 28 years) with ERMs, which were divided into two groups: secondary ERMs (SERMs; n = 28) and idiopathic ERMs (IERMs; n = 13). All 43 eyes underwent 25-gauge vitrectomy and membrane peeling...

BACKGROUND AND OBJECTIVE: To compare vessel density and the foveal avascular zone (FAZ) area among eyes with full-thickness macular hole (FTMH), lamellar macular hole (LMH), and macular pseudohole (MPH) using optical coherence tomography angiography (OCTA). PATIENTS AND METHODS: Cross-sectional study involving 10 eyes with idiopathic FTMH, 10 eyes with LMH, 10 eyes with MPH, 17 unaffected fellow eyes, and 10 healthy controls. All patients underwent 3 mm × 3 mm OCTA centered on the macula...

BACKGROUND AND OBJECTIVE: To investigate the macular perfusion changes in healthy smokers by using optical coherence tomography angiography (OCTA). PATIENTS AND METHODS: OCTA measurements were taken for the right eyes of 40 smokers (Group 1) and age- and sex-matched control cases (Group 2).

Persistent placoid maculopathy (PPM) is a bilateral inflammatory chorioretinopathy characterized by long-standing plaque-like macular lesions. No systemic manifestations have been reported to date. We describe a case of PPM complicated by cerebral vasculitis, suggesting that neurological symptoms, including headache, should be enquired about in all PPM subjects.

INTRODUCTION: The purpose of this study was to evaluate baseline and postoperative factors affecting outcomes after vitrectomy for diabetic macular edema (DME) using optical coherence tomography (OCT). METHODS: Vitrectomy combined with inner limiting membrane (ILM) peeling and additional laser photocoagulation therapy was performed on 36 eyes of 30 DME patients. Evaluations included the logarithm of the minimal angle of resolution (logMAR), best-corrected visual acuity (BCVA) and OCT parameters at baseline and 1, 3, 6, and 12 months postoperatively...

Our recent studies with cultured retinal pigment epithelium cells suggested that overexpression of interleukin 17 receptor C (IL-17RC), a phenomenon observed in peripheral blood and chorioretinal tissues with age-related macular degeneration (AMD), was associated with altered activation of phosphatidylinositide 3-kinase (PI3K), Akt, and glycogen synthase kinase 3 (GSK3). We wondered whether or not altered PI3K, Akt, and GSK3 activities could be detected in peripheral blood mononuclear cells (PBMC) obtained from AMD patients...

Lycium barbarum (wolfberry, gogi berry, gouqizi, ) is one of the most widely used Chinese herbal medicines (CHMs) and is also one of the most scientifically studied. Indeed, the polysaccharide component of this berry (LBP) has been shown to have antioxidant, antiinflammatory, antiexcitotoxic, and antiapoptotic properties. These properties make it a particularly useful treatment option for the ocular environment. Although there are a handful of studies investigating the use of LBP to treat diseases affecting the lens, the vast majority of the published literature investigating LBP in the visual system focus on the retina...
