Three-Dimensional Analysis of Tear Trough Volume After Lower Blepharoplasty with Midface Lift.

This study aims to evaluate three-dimensional stereophotogrammetry measured volume changes in the tear trough area after lower blepharoplasty with midface lift with or without orbital fat manipulation. Among patients undergoing midface lift surgery, volume change by three-dimensional photography in the tear trough region was compared between those having no orbital fat manipulation, fat transposition, or fat resection. This is a prospective study of 260 eyelids of 130 patients who underwent cosmetic midface surgery.

A Prospective Randomized Study of Lateral Brow-Eyelid Complex Volume after Internal Browpexy Using Three-Dimensional Stereophotogrammetry.

A full lateral brow-eyelid complex may help rejuvenate and feminize the face. To compare periorbital volume change of patients as measured by three-dimensional (3D) stereophotogrammetry before and after blepharoplasty with or without internal browpexy sutures. This is a prospective randomized controlled study of 124 eyelids of 62 adult female patients who underwent cosmetic upper eyelid blepharoplasty by a single surgeon.

Tethered capsule en face optical coherence tomography for imaging Barrett's oesophagus in unsedated patients.

Objective: Barrett's oesophagus (BE) screening outside the endoscopy suite can identify patients for surveillance and reduce mortality. Tethered capsule optical coherence tomography (OCT) can volumetrically image oesophageal mucosa in unsedated patients and detect features of BE. We investigated ultrahigh-speed tethered capsule swept-source OCT (SS-OCT), improved device design, developed procedural techniques and measured capsule contact, longitudinal pullback non-uniformity and patient toleration.

Results: Monovision with excimer laser traditionally applies near correction to the non-dominant eye.

Assessment of Barrett's esophagus and dysplasia with ultrahigh-speed volumetric en face and cross-sectional optical coherence tomography.

Background: This study aimed to evaluate the use of ultrahigh-speed volumetric en face and cross-sectional optical coherence tomography (OCT) with micromotor catheters for the in vivo assessment of Barrett's esophagus and dysplasia.

Methods: 74 OCT datasets with correlated biopsy/endoscopic mucosal resection histology (49 nondysplastic Barrett's esophagus [NDBE], 25 neoplasia) were obtained from 14 patients with Barrett's esophagus and a history of dysplasia and 30 with NDBE. The associations between irregular mucosal patterns on en face OCT, absence of mucosal layering, surface signal > subsurface, and > 5 atypical glands on cross-sectional OCT vs.

Tarsal platform show after upper eyelid blepharoplasty with or without brassiere sutures.

Purpose: Increased tarsal platform show (TPS) and decreased brow fat span (BFS) are associated with favorable results in women undergoing cosmetic blepharoplasty. We conducted a study to evaluate the efficacy of upper blepharoplasty with or without a technique (brassiere sutures) to increase TPS and decrease BFS.

Methods: This is a prospective, randomized, comparative, case series study of 100 eyelids (50 consecutive women patients) treated with cosmetic upper blepharoplasty performed by a single surgeon.

Endoscopic optical coherence tomography angiography microvascular features associated with dysplasia in Barrett's esophagus (with video).

Background And Aims: Angiogenesis is associated with neoplastic progression of Barrett's esophagus (BE). Volumetric optical coherence tomography angiography (OCTA) visualizes subsurface microvasculature without exogenous contrast agents. We investigated the association of OCTA microvascular features with low-grade dysplasia (LGD) and high-grade dysplasia (HGD).

Beneficial effects of ankle-foot orthosis daytime use on the gait of Duchenne muscular dystrophy patients.

Background: Orthosis use prevents muscle contracture and prolongs ambulation in patients with Duchenne muscular dystrophy (DMD). However, its biomechanical effects on gait are unclear. This study assessed the effects of daytime and night-time use of Articulated Ankle Foot Orthosis (AFO) on kinematic, kinetic and spatial/temporal gait parameters of DMD patients.

Intrastromal corneal ring segment implantation for ectasia after refractive surgery.

Purpose: To evaluate the clinical outcomes of intrastromal corneal ring segment (ICRS) implantation to correct ectasia in eyes with prior refractive surgery.

Methods: Forty-one eyes of 25 patients (13 men, 12 women; mean age, 28.66 years) with ectasia after refractive surgery [photorefractive keratectomy (PRK) or laser in situ keratomileusis (LASIK)] were included in a nonrandomized, retrospective, observational case series.

Ultrahigh speed endoscopic optical coherence tomography for gastroenterology.

We describe an ultrahigh speed endoscopic swept source optical coherence tomography (OCT) system for clinical gastroenterology using a vertical-cavity surface-emitting laser (VCSEL) and micromotor imaging catheter. The system had a 600 kHz axial scan rate and 8 µm axial resolution in tissue. Imaging was performed with a 3.

Comparison of Tissue Architectural Changes between Radiofrequency Ablation and Cryospray Ablation in Barrett's Esophagus Using Endoscopic Three-Dimensional Optical Coherence Tomography.

Two main nonsurgical endoscopic approaches for ablating dysplastic and early cancer lesions in the esophagus have gained popularity, namely, radiofrequency ablation (RFA) and cryospray ablation (CSA). We report a uniquely suited endoscopic and near-microscopic imaging modality, three-dimensional (3D) optical coherence tomography (OCT), to assess and compare the esophagus immediately after RFA and CSA. The maximum depths of architectural changes were measured and compared between the two treatment groups.

Structural markers observed with endoscopic 3-dimensional optical coherence tomography correlating with Barrett's esophagus radiofrequency ablation treatment response (with videos).

Background: Radiofrequency ablation (RFA) is effective for treating Barrett's esophagus (BE) but often involves multiple endoscopy sessions over several months to achieve complete response.

Objective: Identify structural markers that correlate with treatment response by using 3-dimensional (3-D) optical coherence tomography (OCT; 3-D OCT).

Design: Cross-sectional.

Characterization of buried glands before and after radiofrequency ablation by using 3-dimensional optical coherence tomography (with videos).

Background: Radiofrequency ablation (RFA) is an endoscopic technique used to eradicate Barrett's esophagus (BE). However, such ablation can commonly lead to neosquamous epithelium overlying residual BE glands not visible by conventional endoscopy and may evade detection on random biopsy samples.

Objective: To demonstrate the capability of endoscopic 3-dimensional optical coherence tomography (3D-OCT) for the identification and characterization of buried glands before and after RFA therapy.

Effective treatment of chronic radiation proctitis using radiofrequency ablation.

Endoscopic argon plasma coagulation and bipolar electrocautery are currently preferred treatments for chronic radiation proctitis, but ulcerations and strictures frequently occur. Radiofrequency ablation (RFA) has been successful for mucosal ablation in the esophagus. Here we report the efficacy of RFA with the BarRx Halo(90) system in three patients with bleeding from chronic radiation proctitis.
