Pilot Safety Study of a Microfabricated Device for Anterior Stromal Puncture to Treat Corneal Epithelial Disease in the Optical Axis.

Purpose: Anterior stromal puncture is an inexpensive and widely used technique at the slit lamp to treat recurrent corneal erosions (RCE), common sequelae of corneal abrasions, trauma, and epithelial basement membrane dystrophies (EBMDs). The purpose of this study was to determine safety of a novel anterior stromal micropuncture device (termed a "plexitome") for use in the optical axis of the cornea.

Methods: We performed an IRB-approved clinical pilot study on 45 patients with diverse corneal pathologies to determine the safety of the plexitome device and examined corneal healing responses clinically for a minimum of 30 days after treatment.

Integration of Large-Area Halide Perovskite Single Crystals and Substrates via Chemical Welding Using an Ionic Liquid for Applications in X-ray Detection.

The large carrier lifetime mobility product and strong stopping power for high-energy X-rays make halide perovskites an attractive candidate for next-generation X-ray detectors. In particular, high-energy X-rays in the range of several tens of keV require halide perovskite absorber layers with thicknesses exceeding a few millimeters. To avoid carrier scattering caused by grain boundaries at such thicknesses, the utilization of single crystals is desirable.

Orbital emphysema as a result of chest tube placement for recurrent pneumothorax.

Orbital emphysema refers to the presence of air or gas within the orbital soft tissue space. Although orbital fracture due to trauma is the most common cause, iatrogenic orbital emphysema from chest tube insertion is a rare but potentially serious complication from the treatment of pneumothorax. Symptoms can range from mild crepitus of the periorbital region to permanent vision loss secondary to central retinal artery occlusion or optic neuropathy, a result of orbital compartment syndrome.

The mixture of Ledeb. and Bunge. extract produces analgesic and anti-inflammatory effects in a collagen-induced arthritis mouse model.

Pain and inflammation typically manifest in patients with arthritis. It is now widely known that Ledeb (AP) and Bunge (SM) exert anti-inflammatory and antinociceptive effects. We have previously reported that the mixture extract (ME) from AP and SM produces antinociceptive and anti-inflammatory effects in gout arthritis and monoiodoacetate (MIA)-induced arthritis models.

Malignant glaucoma presenting with uncontrolled intraocular pressure and myopic refractive surprise after cataract surgery.

We present a seemingly typical case of bilateral angle closure with elevated intraocular pressures. After cataract surgery, there was axial shallowing, escalating intraocular pressure, anterior displacement of the IOL, and myopic shift in the left eye. Irido-zonulo-hyaloido-vitrectomy resolved the angle closure, normalized intraocular pressure, and corrected the myopic shift.

Implementation of the Corneal Sweep Test in the Diagnosis of Recurrent Corneal Erosion: A 2-Year Retrospective Study.

Purpose: The purpose of this study was to evaluate the incidence and epidemiology of recurrent corneal erosion within a clinical population using standard diagnostic techniques and a new technique called the corneal sweep test (CST).

Methods: A retrospective chart review was conducted on 58 eyes of 51 patients with the diagnosis of recurrent corneal erosion from July 2018 to June 2020. All underwent a thorough history and physical examination.

Tape Splint Tarsorrhaphy for Persistent Corneal Epithelial Defects.

Purpose: To report outcomes of tape splint tarsorrhaphy (TST) for persistent corneal epithelial defects (PCED).

Design: Retrospective, interventional case series.

Methods: The study population was consecutive patients with a PCED (14 days or longer) treated at a tertiary cornea clinic with TST.

Cataract incision-related corneal erosion: recurrent corneal erosion because of clear corneal cataract surgery.

Three patients developed recurrent corneal erosions (RCEs) over their cataract surgery corneal incisions. These cataract incision-related corneal erosions (CIRCEs) resulted in pain after cataract surgery. None had any physical findings for corneal erosion; thus, a new technique called the corneal sweep test was developed to identify the erosion.

Trailing-haptic-first modification of double-needle intrascleral haptic fixation technique.

The Yamane double-needle intrascleral haptic fixation technique for posterior chamber intraocular lens (IOL) fixation in the setting of absent or inadequate capsule support is a minimally invasive IOL fixation technique that requires scleral incisions using needles to externalize the IOL haptics. Despite being a seemingly easy and intuitive procedure, there are significant challenges when learning this technique. The most difficult step is threading the trailing haptic with the needle for fixation.

Double-chop: Modified-chop technique eliminating ultrasonic energy and vacuum for lens fragmentation.

Unlabelled: Ultrasound (US) energy and vacuum are necessary for most nuclear disassembly techniques, but the use of US energy and vacuum poses potential risks to intracameral structures, including the corneal endothelium, iris, zonular fibers, and posterior capsule. A wide range of techniques involve sculpting, chopping, prechopping, and femtosecond laser-assisted fragmentation. However, these techniques are limited by high US energy, high vacuum to grab and hold the lens, additional instrumentation, or cost.

All-optical single-sideband frequency upconversion utilizing the XPM effect in an SOA-MZI.

An all-optical single sideband (OSSB) frequency upconverter based on the cross-phase modulation (XPM) effect is proposed and experimentally demonstrated to overcome the power fading problem caused by the chromatic dispersion of fiber in radio-over-fiber systems. The OSSB frequency upconverter consists of an arrayed waveguide grating (AWG) and a semiconductor optical amplifier Mach-Zehnder interferometer (SOA-MZI) and does not require an extra delay line used for phase noise compensation. The generated OSSB radio frequency (RF) signal transmitted over single-mode fibers up to 20 km shows a flat electrical RF power response as a function of the fiber length.

Characterization of a new bacteriocin, Carocin D, from Pectobacterium carotovorum subsp. carotovorum Pcc21.

Two different bacteriocins, carotovoricin and carocin S1, had been found in Pectobacterium carotovorum subsp. carotovorum, which causes soft-rot disease in diverse plants. Previously, we reported that the particular strain Pcc21, producing only one high-molecular-weight bacteriocin, carried a new antibacterial activity against the indicator strain Pcc3.

Cross chop: Modified rotationless horizonal chop technique for weak zonules.

Cross chop is a modified horizontal chop technique that enables safe and efficient lens disassembly without torquing the lens within the capsular bag.

Methods: Unilateral PRK was performed on 21 New Zealand albino rabbits. Three groups, each consisting of six rabbits, were randomized to receive twice-weekly treatments with DHA, NGF, or NGF plus DHA delivered by collagen shield.

(2R,7S)-diacetoxytridecane: sex pheromone of the aphidophagous gall midge, Aphidoletes aphidimyza.

In a recent study, evidence was presented that females of the aphidophagous midge Aphidoletes aphidimyza (Rondi) (Diptera: Cecidomyiidae) release a sex pheromone to attract mates. Our objectives were to identify and bioassay the pheromone. Coupled gas chromatographic-electroantennographic detection(GC-EAD) analyses of untreated and hydrogenated pheromone extract on three fused-silica columns (DB-5, DB-23, DB-210) revealed a single compound that elicited responses from male antennae.
