Background: To evaluate the relationship between superficial, deep foveal avascular zone (FAZ) and foveal cyst areas in eyes with cystoid macular oedema (CMO) associated with gyrate atrophy of the choroid and retina (GA).
Methods: This is a retrospective collaborative multicenter study of optical coherence tomography-angiography (OCTA) images in GA. Superficial and deep FAZ and foveal cyst were measured using Image J by two independent experts. Values were corrected for myopia magnification. These values were compared with age-matched controls from normative data.
Results: Twenty-three eyes from 12 patients with GA and CMO were included in the study. The mean ± standard deviation age was 22 ± 19.7 years, mean Snellen spectacle-corrected visual acuity of 20/70 with mean myopia of 5.7 ± 4.1 dioptres. Qualitatively, no focal occlusion of superficial and deep capillary plexus was noted. Mean superficial FAZ area (0.484 ± 0.317 mm), deep FAZ area (0.626 ± 0.452 mm), and foveal cyst area (0.630 ± 0.503 mm) were significantly larger than superficial and deep FAZ areas in controls of same age range (p < 0.001). Macular cyst area correlated with superficial FAZ area (R = 0.59; p = 0.0057) and more strongly with deep FAZ area (R = 0.69; p < 0.001).
Conclusions: The superficial and deep FAZ area in GA-associated CMO were noted to be significantly larger than in controls. It seems that RPE dysfunction leads to foveal cyst enlargement displacing the capillary plexus with resultant enlarged superficial and deep FAZ area.

The demand for aesthetic surgery continues to increase, and it is therefore essential to ensure that the next generation of plastic surgeons are adequately trained. We propose a safe method in aesthetic training in abdominoplasty and facelift, utilizing free deep inferior epigastric perforator (DIEP) flap and parotidectomy for training aesthetic procedures. The trainees' focus differed between the 2 procedures.

Purpose: To investigate the repeatability of optical coherence tomography angiography (OCTA) parameters in participants with different severities of glaucoma.
Methods: Subjects with open-angle glaucoma were enrolled prospectively and categorised into mild (mean deviation [MD] of 24-2 visual field test ≥ -6 dB), moderate to advanced (-6 > MD ≥ -20 dB) and severe glaucoma groups (MD < -20 dB). OCTA was performed three times within a single visit to obtain superficial and deep macular vessel density (VD) and peripapillary vessel and capillary density.

In the last few years, the Deep Plane Face Lift (DPFL) has gained great popularity among plastic surgeons, even if its origins are traced back to the 1970s. Certainly, it could have some advantages but based on our experience, it can reveal some unpleasant features in the long term. For this reason, the senior authors have adopted the high superficial musculoaponeurotic system (SMAS) Face Lift for many years in their surgical practice.

Background: The goal of the study is to use CT imaging in patients with aSAH to evaluate the anatomic distribution of hemorrhage and compartmentalization of subarachnoid space to investigate potential in vivo visualization of recently discovered layer named subarachnoid lymphatic-like membrane (SLYM).
Methods: We conducted a retrospective cohort study of cases with aneurysmal SAH (aSAH) at our institution between January 2015 and June 2022. Subarachnoid hemorrhage distribution into superficial and deep subarachnoid spaces was classified based on proximity to the dural or pial surfaces, respectively, as seen on multiplanar CT head.

The absence of a clear consensus on the definition and significance of fascia and the indiscriminate use of the term throughout the clinical and scientific literature has led to skepticism regarding its importance in the human body. To address this challenge, we propose that: (1) fasciae, and the fascial interstitia within them, constitute an anatomical system, defined as a layered body-wide multiscale network of connective tissue that allows tensional loading and shearing mobility along its interfaces; (2) the fascial system comprises four anatomical organs: the superficial fascia, musculoskeletal (deep) fascia, visceral fascia, and neural fascia; (3) these organs are further composed of anatomical structures, some of which are eponymous; (4) all these fascial organs and their structural components contain variable combinations and arrangements of the four classically defined tissues: epithelial, connective, muscle, and neural; (5) the overarching functions of the fascial system arise from the contrasting biomechanical properties of the two basic types of layers distributed throughout the system: one predominantly collagenous and relatively stiff, the other rich in hyaluronic acid and viscous, allowing for the free flow of fluid; (6) the topographical organization of these layers in different locations is related to local variations in function (e.g.
