Purpose: To compare the outcomes of standard pop-titrated transscleral cyclophotocoagulation (TSCPC) and slow-coagulation TSCPC in the treatment of glaucoma.
Design: Retrospective case series.
Subjects: This study included 78 eyes with glaucoma of any type or stage that underwent TSCPC as part of their treatment course.
Methods: This study compared 52 eyes treated with slow coagulation TSCPC to 26 eyes treated with standard pop-titrated TSCPC. Patient demographics, treatment course, surgical techniques, settings and outcomes were assessed.
Main Outcome Measures: The main outcome measures were visual acuity (VA), intraocular pressure (IOP) and post-surgical complications.
Results: The initial LogMAR VA was 1.94 (0.73) [mean (SD)] in the slow coagulation TSCPC group and 1.71 (0.90) in the standard TSCPC group (p=0.507). Initial IOP was 37 (13) mm Hg in the slow coagulation group and 39 (13) mm Hg in the standard group (p=0.297). The follow-up periods were 16.36 months and 24.68 months for the slow coagulation and standard groups (p=0.124). VA remained better than light-perception in 71.1% of slow coagulation treated patients and 65.0% of standard TSCPC treated patients (p=0.599). IOP remained below 20 mm Hg in 46% of slow coagulation treated patients and 44% of standard TSCPC treated patients (p=0.870). The mean number of complications was higher in the standard group [1.46 (1.24)] versus the slow coagulation group [0.62 (0.75)] (p=0.002). The incidence of the need for a second procedure (slow coagulation- 28.8%, standard- 23.1%, p=0.588) and maximum number of medications needed to control IOP postoperatively (p=0.771) were similar between the two groups.
Conclusions: In this case series, slow coagulation TSCPC and standard pop-titrated TSCPC resulted in similar VA and IOP outcomes in the treatment of glaucomatous eyes. The complication profiles of the techniques were also comparable, although standard TSCPC had a higher incidence of prolonged inflammation postoperatively. This study suggests that slow coagulation TSCPC may achieve equivalent control of IOP while reducing the incidence of prolonged post-operative inflammation-a feared complication of TSCPC-when compared to standard "pop-titrated" TSCPC.

Phase separation, a fundamental phenomenon in both natural and industrial settings, involves the coarsening of domains over time t to reduce interfacial energy. While well-understood for simple viscous liquid mixtures, the physical laws governing coarsening dynamics in complex fluids, such as colloidal suspensions, remain unclear. Here, we investigate colloidal phase separation through particle-based simulations with and without hydrodynamic interactions (HIs).

BACKGROUND Vestibular schwannoma is a slow-growing benign tumor arising from the 8th cranial nerve. It can originate in the cerebellopontine angle (CPA). This retrospective study aimed to investigate the factors associated with outcomes following surgical resection of vestibular schwannoma in the CPA in 30 patients at a single center in Turkey, focusing on postoperative intratumoral hemorrhage.

Purpose: To evaluate the outcomes of slow-coagulation transscleral cyclophotocoagulation (SC-TSCPC) in pseudoexfoliation glaucoma (PXG).
Methods: A single-center, retrospective non-comparative study including consecutive patients with medically uncontrolled PXG who underwent SC-TSCPC (1250-milliwatt power and 4-second duration). The primary outcome measure was surgical success (defined as intraocular pressure (IOP) between 6 - 21 mmHg with ≥20% reduction compared to baseline and no need for further glaucoma surgeries or development of vision-threatening complications).

To evaluate the clinical efficacy of modified endoscopic mucosal resection (EMR) in the management of early gastrointestinal lesions. Upon endoscopic identification of the lesion, normal saline is injected into the submucosa to establish a fluid cushion, which elevates the lesion's mucosa. Methylene blue may also be applied to improve visualization of the relationship between the submucosa and muscular layer.

Slow transformation efficiency of Fe(III)/Fe(II) limits the generation of radicals in peroxymonosulfate (PMS)-based advanced oxidation processes (AOPs), and these radicals was easy to be interfered by the presence of water constituents. In addition, in-situ coagulation during this oxidation process was neglected. This study proposed Fe(II)/PMS-Mn(VII) in the presence of chlorides ions (FPMC) process to reveal multiple promoting effects of Mn on redox cycle of Fe(III)/Fe(II) and different reactive mechanisms of Cl on types of radicals generation pathways, and the in-situ coagulation enhanced mechanisms was investigated.
