Morphological studies of the cadaveric sclera after nonpenetrating sclerotomy by ND: YAG laser

Российский офтальмологический журнал, 2018
Purpose: to reveal the changes of the morphological structure of cadaveric human sclera after Nd: YAG laser irradiation.Material and methods. Laser pulses (Nd: YAG) (Lumenis) (power 7.0–7.4 mW, pulse duration 4 ns, wavelength 1064 nm) were applied to the

Motion of the vitreous humour in a deforming eye -- fluid-structure interaction between a nonlinear elastic solid and a nonlinear viscoleastic fluid [PDF]

, 2018
We study the motion of vitreous humour in a deforming eyeball. From the mechanical and computational perspective this is a task to solve a fluid-structure interaction problem between a complex viscoelastic fluid (vitreour humour) and a nonlinear elastic solid (sclera and lens).

Morphological changes of sclera in rats with experimental myopia [PDF]

Морфологія, 2014
Background. The absence of adequate experimental myopia model is the actual problem in pathophysiological studying of the myopia progression. Studies of the chick eye have formed the basis for several hypotheses of myopic development.

A Comparative Study of Age-Related Level of Sclera Collagen Crosslinking in Patients with Different Stages of Primary Open Angle Glaucoma

Российский офтальмологический журнал, 2018
Age-related levels of sclera collagen crosslinking have been studied in 75 patients aged 50-91 (averagely 69.9 ± 9.2 years) with various degrees of primary open angle glaucoma (POAG), whose sclera samples were obtained during deep nonpenetrating ...

Outcomes of the intraoperative relaxed muscle positioning technique in strabismus surgery for thyroid eye disease

Pediatric Investigation, EarlyView.
The intraoperative relaxed muscle positioning technique is a useful surgical tool in treating thyroid eye disease‐related restrictive strabismus. ABSTRACT Thyroid eye disease (TED) can cause incomitant strabismus with muscle restriction, resulting in diplopia and patient discomfort and discontent.

Sclera-Net: Accurate Sclera Segmentation in Various Sensor Images Based on Residual Encoder and Decoder Network

IEEE Access, 2019
Sclera segmentation is revealed to be of noteworthy importance for ocular biometrics. The paramount step for biometric recognition methods is the segmentation of the area of interest, i.e., the sclera in our case.

Activated mTOR Signaling in the RPE Drives EMT, Autophagy, and Metabolic Disruption, Resulting in AMD‐Like Pathology in Mice

Aging Cell, EarlyView.
Our study reveals that overactivation of both mTOR complexes through mLST8 in RPE cells triggers AMD‐like pathology and cellular dysfunction. This finding highlights the critical role of balanced mTOR signaling in retinal health and suggests that targeting both complexes could be therapeutic for AMD treatment.

Two‐year changes of macular choroidal thickness in response to 0.01% atropine eye drops: Results from the myopia outcome study of atropine in children (MOSAIC) clinical trial

Acta Ophthalmologica, EarlyView.
Abstract Purpose To investigate 2‐year changes in macular choroidal thickness (ChT) in children receiving 0.01% atropine eyedrops and its relationship with spherical equivalent refraction (SER) progression and axial length (AL) elongation. Methods A total of 250 myopic children aged 6–16 years (167%–0.01% atropine, 83‐placebo) were enrolled in the ...

An Improved Algorithm for Eye Corner Detection [PDF]

IEEE Conference on Signal Processing and Communications SPCOM, 2016, 2015
In this paper, a modified algorithm for the detection of nasal and temporal eye corners is presented. The algorithm is a modification of the Santos and Proenka Method. In the first step, we detect the face and the eyes using classifiers based on Haar-like features. We then segment out the sclera, from the detected eye region. From the segmented sclera,

One tube for all: 1‐year outcomes after transition to Paul glaucoma implant at a tertiary centre

Acta Ophthalmologica, EarlyView.
Abstract Purpose To evaluate the intraocular pressure (IOP) lowering effect and success rate of Paul glaucoma implant (PGI) in refractory glaucoma after changing practice pattern from Ahmed and Baerveldt tubes to PGI. Methods A prospective observational study of the first 50 consecutive PGI surgeries at a single Danish tertiary centre from January 2022
