BACKGROUND: A lamellar macular hole (LMH) is characterized by a distinct morphologic configuration and can be distinguished from related entities such as macular pseudohole (MPH) and epiretinal membrane with foveoschisis (ERM-FS) by clear morphologic features.
OBJECTIVE: Based on current knowledge, the pathophysiologic function of LMH in the spectrum of vitreomacular interface diseases will be described and therapeutic concepts will be presented.
METHODS: Current studies are supplemented by case reports to provide a schematic overview of the natural history and therapeutic concepts at the vitreomacular interface.
RESULTS: The LMH is as a retrospective marker for pathologic posterior vitreous detachment in adult patients and may be interpreted as the pathophysiologic center of tractional maculopathies. Various vitreomacular pathologies can result in LMH: a detached vitreomacular traction, a spontaneously closed penetrating macular hole, or an epiretinal membrane with foveoschisis. Pathophysiologically, a degenerative, progressive loss of the architecture of the foveal muller cell cone may be the underlaying mechanism, resulting in the typical undermining of the hole edges and occasionally in a full thickness macular hole. The optimal timing and the appropriate surgical method are the focus of current clinical studies.
CONCLUSIONS: The pathophysiology of LMH indicates a smooth transition of tractive maculopathies. These should be prospectively evaluated in order to develop evidence-based treatment strategies for LMH.
UNASSIGNED: HINTERGRUND: Das Makulaschichtforamen (LMH) zeichnet sich durch eine differenzierte, morphologische Konfiguration aus und lässt sich anhand eindeutiger morphologischer Merkmale von nahestehenden Entitäten wie dem makulären Pseudoforamen (MPH) und der epiretinalen Membran mit Foveoschisis (ERM-FS) abgrenzen. ZIEL: Anhand des aktuellen Wissenstands soll die pathophysiologische Funktion des LMH im Spektrum vitreoretinaler Grenzflächenerkrankungen beschrieben und therapeutische Konzepte sollen vorgestellt werden.
METHODS: Die verfügbare Studienlage wird durch Fallberichte erweitert, um zu einer schematischen Übersicht der Spontanverläufe und Therapiekonzepte am vitreomakulären Übergang zu gelangen.
UNASSIGNED: Das Makulaschichtforamen kann beim erwachsenen Patienten als retrospektiver Marker für eine stattgehabte pathologische hintere Glaskörperabhebung interpretiert werden und steht im pathophysiologischen Zentrum der traktiven Makulopathien. Verschiedene vitreomakuläre Pathologien können in einem LMH resultieren: eine gelöste vitreomakuläre Traktion, ein spontan verschlossenes durchgreifendes Makulaforamen oder eine epiretinale Membran mit Foveoschisis. Pathophysiologisch ist von einem degenerativen, progressiven Verlust der Architektur des fovealen Müller-Zell-Konus auszugehen, der in der typischen Unterminierung der Lochränder und vereinzelt im Verlauf auch in einem durchgreifenden Makulaforamen münden kann. Der optimale Zeitpunkt sowie die adäquate Operationsmethode stehen im Fokus aktueller klinischer Studien.
UNASSIGNED: Die Pathophysiologie des LMHs deutet auf einen fließenden Übergang der traktiven Makulopathien hin, die standardisiert und prospektiv ausgewertet werden sollten, um evidenzbasierte Therapiestrategien beim LMH entwickeln zu können.

BACKGROUND: Laser skin resurfacing is a popular cosmetic procedure for noninvasive skin rejuvenation. Since health insurance plans often do not cover these types of procedures, patients often pay out of pocket. Consequently, there is an incentive to go abroad, where prices are more affordable. However, practitioners in destination countries may lack rigorous training on laser safety, regulatory oversight, or licensing, especially on devices used for \"cosmetic\" procedures. In certain cases, this can lead to tragic outcomes, especially when underqualified practitioners operate medical-grade laser devices.
METHODS: A 29-year-old woman suffered a retinal burn from a handheld Q-switched neodymium-doped yttrium aluminum garnet (Nd:YAG) laser pulse device used to perform skin resurfacing treatment at a medical spa in Vietnam. The patient was not adequately informed about the potential risk to her vision and was not provided with any eye protection. A momentary, unintended laser exposure to the patient\'s right eye led to irreversible vision loss due to a macular burn. This incident caused immediate pain, followed by the sudden appearance of floaters, along with a retinal and vitreous hemorrhage. Despite treatment with off-label bevacizumab for the development of a choroidal neovascular membrane, vision remained at the level of counting fingers because of the presence of the macular scar.
CONCLUSIONS: When utilizing laser-based devices, it is crucial to employ safety measures, such as the wearing of safety goggles or the use of eye shields to protect ocular tissues from potential damage. The growing availability of cosmetic laser devices presents a substantial public health risk, because numerous operators lack adequate training in essential safety standards, or they neglect to follow them. Furthermore, patients seeking services abroad are subject to the regulatory practices of the destination country, which may not always enforce the requisite safety standards. Further research is needed to determine regional and global incidence of laser-related injuries to help direct educational and regulatory efforts.

Purpose: To describe a case of postoperative persistent loculated subretinal fluid (SRF) that developed after pars plana vitrectomy (PPV) for vitreomacular traction (VMT) syndrome. Methods: A case was analyzed and a literature review performed. Results: A healthy 64-year-old man with no significant ocular history presented with persistent, symptomatic VMT. Combined phacoemulsification and PPV, epiretinal membrane and internal limiting membrane peeling, and gas-fluid exchange were performed. Postoperative spectral-domain optical coherence tomography imaging showed loculated foveal SRF. The SRF persisted for 8 months, with minimal change in size and little best-corrected visual acuity improvement. Conclusions: Although persistent loculated SRF has been reported after vitrectomy for rhegmatogenous retinal detachment (RD) in high myopia and tractional RD in diabetes, it has not yet been reported postoperatively after PPV for VMT. Studies of the pathophysiology and long-term course of persistent SRF after PPV for VMT are needed to inform management decisions for this rare complication.

OBJECTIVE: Vitreomacular traction (VMT) has unique presentations in eyes with diabetic retinopathy (DR). This study aimed to investigate the characteristics and clinical course of VMT in DR.
METHODS: A retrospective case series.
METHODS: Thirty eyes from 30 patients with DR and concurrent VMT were retrospectively enrolled. Baseline and final best-corrected visual acuity (BCVA) and optical coherence tomography (OCT) characteristics were reported. Linear regression models were used to analyze the correlating factors for visual outcome.
RESULTS: Of the 30 eyes, a thickened posterior hyaloid membrane was noted in all cases and multi-layered traction from different directions in 14 eyes (46.7%). Twenty-one eyes (70%) had tractional macular retinoschisis, seven (23.3%) had foveal detachment, five (16.7%) had a lamellar macular hole, and three (10%) had a full-thickness macular hole, including two with macular hole retinal detachment. Three eyes had spontaneous release of the VMT within 3 months of observation. For the remaining 27 eyes receiving operations, the VMT, full-thickness macular hole, and serous foveal detachment all resolved postoperatively with residual macular schisis in 6 eyes (22.2%) only. None of the baseline OCT characteristics were associated with postoperative BCVA (P > .05).
CONCLUSIONS: VMT in DR had a thickened posterior hyaloid, and many of them had multi-layered traction and/or concurrent macular retinoschisis. Lamellar macular hole, full-thickness macular hole, or concurrent retinal detachment may also occur. Spontaneous resolution of VMT rarely occurred, and those who underwent operation for VMT had improved vision and macular structures with resolution of the macular hole and retinal detachment.

BACKGROUND: Intravitreal anti-vascular endothelial growth factor (VEGF) is the standard treatment for exudative age-related macular degeneration (AMD). The constitution of the vitreomacular interface varies greatly in cases of attached (with or without traction) or detached vitreous body, which can impact the effectiveness of the anti-VEGF treatment.
OBJECTIVE: Based on the current literature this article displays the current state of the science on whether the constitution of the vitreous body has an effect on the anti-VEGF treatment.
METHODS: The published data extracted from current trials and post hoc analyses concerning this topic are presented and put into the clinical context.
RESULTS: The presence of a vitreomacular adhesion reduces the efficacy of anti-VEGF treatment of exudative AMD. Posterior vitreous body detachment represents a positive prognostic factor concerning the efficacy of anti-VEGF treatment but not necessarily the prognosis for visual acuity.
CONCLUSIONS: Patients with attached vitreous body need a more intensive treatment monitoring compared to patients with detached vitreous body. Therefore, in eyes with initial posterior vitreous body detachment receiving a treat and extend regimen, the interval between anti-VEGF injections can be extended to 4 instead of 2 weeks without endangering the success of treatment.
UNASSIGNED: HINTERGRUND: Die Anti-VEGF(„vascular endothelial growth factor“)-Therapie ist die Standardtherapie zur Behandlung der exsudativen altersabhängigen Makuladegeneration (AMD). Bei anliegendem (mit oder ohne Traktion) oder abgehobenem Glaskörper besteht eine stark unterschiedliche Beschaffenheit des vitreomakulären Interface. Dies kann Auswirkungen auf die Effektivität der Anti-VEGF-Therapie haben.
UNASSIGNED: Es erfolgt die Darstellung des aktuellen Stands der Wissenschaft, ob und inwiefern die Beschaffenheit des Glaskörpers einen Einfluss auf die Anti-VEGF-Therapie hat.
METHODS: Die zu diesem Thema publizierten Daten aus klinischen Studien werden aufgeführt und in den klinischen Kontext gesetzt.
UNASSIGNED: Das Vorliegen einer vitreomakulären Adhäsion reduziert die Effektivität der Anti-VEGF-Therapie. Bezogen auf die Effektivität, aber nicht unbedingt auf die Visusprognose stellt die hintere Glaskörperabhebung einen prognostisch günstigen Faktor dar.
CONCLUSIONS: Patienten mit anliegendem Glaskörper benötigen ggf. eine intensivere Therapieüberwachung als Patienten mit einem abgehobenen Glaskörper. Deshalb kann bei Anwendung eines Treat-and-Extend-Schemas eine Intervallverlängerung bei Patienten mit initial abgehobenen Glaskörper ggf. schneller vorgenommen werden (4 anstatt 2 Wochen), ohne den Erfolg der Anti-VEGF-Therapie zu gefährden.

Epiretinal membranes (ERMs) typically remain stable or progressively worsen. Here, we report two rare cases of spontaneous ERM regression and one case of ERM separation. This is a case series of three patients. The patients\' clinical data were collected and ERMs were evaluated with serial optical coherence tomographies (OCTs). Cases one and two were female patients presenting with floaters. Mild-to-moderate idiopathic ERM was diagnosed which spontaneously regressed over the following years without intervention and evidence of separation. Patients\' vision was slightly decreased or remained stable, respectively. Case three was a female patient presenting with blurry vision. A mild ERM was diagnosed with vitreomacular traction (VMT) and a tiny macular hole. Over the following three months, ERM separation along with VMT release was evidenced on OCT. The macular hole healed simultaneously. Her vision improved from 20/70 to 20/30. The possibility of spontaneous regression of idiopathic ERMs should be a factor to consider in management. Further research must be done to determine the mechanism of this phenomenon.

The vitreous body is an anatomically and biochemically complex structure. Because of its proximity and firm adherence to the retina, researchers have examined the link between these two structures and how their individual pathologies might be connected. Several experimental and clinical studies have already demonstrated the important role of vitreous in the pathogenesis of retinal disorders. This narrative review highlights the role of the vitreous in retinal diseases and the improvements that have been made since the introduction of optical coherence tomography. This leads to a better understanding of vitreoretinal diseases and demonstrates its determinant role in other retinal pathologies, such as diabetic retinopathy or age-related macular degeneration. As we deepen our knowledge of the vitreous\'s structure, function, and abnormal conditions, we can better link the changes in diseases and identify effective treatments.

BACKGROUND: The aim of this study was to examine if choroidal vascularity index (CVI) is different in eyes with unilateral vitreomacular traction (VMT) from their healthy fellow eyes; and whether different treatments affect the CVI.
METHODS: The baseline and 8-week post treatment CVIs of 56 unilateral VMT patients that underwent spontaneous resolution (n = 30), vitreoretinal surgery (n = 16) or pneumatic vitreolysis (n = 10) were compared with fellow eyes using paired samples t-test. Partial correlation analyses correcting age and gender was used for calculations between treatment groups. P values < 0.05 were considered statistically significant.
RESULTS: The mean baseline CVI for VMT and control eyes had no statistically significant difference (p = 0.81, r= -0.38). The post traction release follow-up CVI of VMT eyes and contralateral eyes had no significant difference (p = 0.12, r = 0.49). In spontaneous resolution group, vitreoretinal surgery group and pneumatic vitreolysis group the baseline and follow up CVIs of VMT eyes were statistically similar (p = 0.72, p = 0.32 and p = 0.79 respectively).Spontaneous detachment patients\' CVIs showed a 0.57±5.81% increase, vitreoretinal surgery group had a reduction of 1.098±4.76%, and the pneumatic vitreolysis patients showed a CVI reduction of 0.307±4.24%. However, none of these changes was found to be statistically significant when compared between the groups (p = 0.21, r = 0.02).
CONCLUSIONS: Previous studies have argued that vitreomacular traction might have a role on the choroidal changes seen in the vitreoretinal interface disorders. This study has shown that VMT alone does not cause any significant changes in choroidal vascular index pre or post traction release.

BACKGROUND: To measure the degree of curvature of the retinal artery trajectory (RAT) and retinal vein trajectory (RVT) in the eyes of patients with vitreomacular traction (VMT) and compare them with their healthy fellow eyes.
METHODS: This was a retrospective, cross-sectional, case-control study of 58 eyes of 29 patients with unilateral VMT. The participants were divided into two groups. Group 1 VMT was defined as having only morphological changes, while group 2 VMT was defined as morphological changes accompanied by the presence of a cyst or hole to quantify the severity of the disease. The RATs and RVTs were assessed from the color fundus photographs using the ImageJ program. The fundus photographs were rotated 90°. The course of the retinal arteries and veins were marked on a color fundus photograph and fitted to a second-degree polynomial curve (axe[x]/100+bx+c). The coefficient \'\'a\'\' was the width and steepness of the trajectories. The comparison between the RAT and RVT of VMT and healthy fellow eyes was investigated and the association between the RAT and RVT and the severity of disease were determined using the Image J program.
RESULTS: Eleven subjects were male, and 18 subjects were female. The mean ± SD age was 70.6 ± 7.6 years. Eighteen of the eyes had VMT in the right and 11 of the eyes had VMT in the left eye. Eleven eyes were in group 1 and 18 eyes were in group 2. Axial length (AL) was similar between the two groups (22.63 ± 1.20 mm vs 22.45 ± 1.45 mm p = 0.83) (Table 1). The mean RAT was 0.60 ± 0.18 in eyes with VMT and 0.51 ± 0.17in healthy eyes (p = 0.063). The mean RVT was 0.74 ± 0.24 in eyes with VMT and 0.62 ± 0.25 in healthy eyes for the whole group (p = 0.02). In group 1, the mean RVT of the eyes with VMT was statistically significantly higher than the healthy eyes (p = 0.014). There was not any statistically significant difference for the other parameters evaluated between eyes with VMT and healthy eyes according to the groups and the whole group. (Tables 2-4) CONCLUSION: Unlike other vitreoretinal interface diseases such as epiretinal membrane and macular hole, VMT may be characterized by a narrower RVT, which is characterized by a larger \"a\" value.

UNASSIGNED: To report a case of release of vitreomacular traction (VMT) in a patient with a full thickness macular hole (FTMH) immediately following pneumatic vitreolysis (PV) combined with head bobbing movements.
UNASSIGNED: A 71-year-old female with VMT and an FTMH presented with blurred vision for 2 months to the level of 20/400. At her 1-month follow-up visit, PV was performed using C3F8 gas and she was instructed to perform the drinking bird technique for ten minutes.
UNASSIGNED: Optical coherence tomography performed ten minutes after PV with head bobbing showed VMT release and a smaller FTMH. Visual acuity improved to 20/150 immediately afterwards and to 20/80 two months later.
UNASSIGNED: Using the drinking bird technique for a continuous period of time immediately following PV may encourage rapid VMT release. PV may be a feasible option for patients with VMT and FTMH who do not want surgery.
