The purpose of this study was to observe effects of wearing textured insoles and clinical compression socks on organisation of lower limb interceptive actions in developing athletes of different skill levels in association football. Six advanced learners and six completely novice football players (15.4±0.9years) performed 20 instep kicks with maximum velocity, in four randomly organised insoles and socks conditions, (a) Smooth Socks with Smooth Insoles (SSSI); (b) Smooth Socks with Textured Insoles (SSTI); (c) Compression Socks with Smooth Insoles (CSSI) and (d), Compression Socks with Textured Insoles (CSTI). Reflective markers were placed on key anatomical locations and the ball to facilitate three-dimensional (3D) movement recording and analysis. Data on 3D kinematic variables and initial ball velocity were analysed using one-way mixed model ANOVAs. Results revealed that wearing textured and compression materials enhanced performance in key variables, such as the maximum velocity of the instep kick and increased initial ball velocity, among advanced learners compared to the use of non-textured and compression materials. Adding texture to football boot insoles appeared to interact with compression materials to improve kicking performance, captured by these important measures. This improvement in kicking performance is likely to have occurred through enhanced somatosensory system feedback utilised for foot placement and movement organisation of the lower limbs. Data suggested that advanced learners were better at harnessing the augmented feedback information from compression and texture to regulate emerging movement patterns compared to novices.

BACKGROUND: Subliminal transscleral cyclophotocoagulation (SL-TSCPC) is a new alternative therapy to reduce intraocular pressure (IOP) safely and effectively. However, there are few studies regarding SL-TSCPC by Supra 810 laser machine and limited data regarding its effectiveness in moderate severity glaucoma that still has good preservation of vision. This study was conducted to evaluate the outcome of SL-TSPCPC in various types of glaucoma including patients with good vision.
METHODS: A retrospective, non-comparative, analytical case series of all patients who received SL-TSCPC treatment from October 2018 to April 2019 at Hospital Tengku Ampuan Afzan, Pahang, Malaysia. Data was collected during the second week, sixth week, third month and sixth month follow-up. The primary outcome measure gave success rate at six months post-treatment. Secondary measures were changes in visual acuity, mean IOP reduction, mean number of IOP lowering medications reduced and ocular side effects noted during follow-up.
RESULTS: The success rate was 43.8% (seven eyes out of sixteen eyes) at six months post-treatment. The mean IOP reduced from 43.0mmHg±14.8mmHg pre-treatment to 24.7mmHg±12.0mmHg at two weeks post treatment with 42.6% reduction. Subsequently, mean IOP at sixth week, third month and sixth month were 33.8mmHg±16.9mmHg, 35.2mmHg±14.9mmHg, and 29.0mmHg±16.2mmHg respectively. Vision maintained in 13 patients, two patients had improvement in vision however, five patients had deterioration in vision. No serious ocular side effects were noted.
CONCLUSION: Subliminal TSCPC is a safe and alternative method of lowering IOP in moderate to advanced glaucoma over 6 months duration of follow-up. As it has good safety profile and repeatability, it is a good treatment option for patients with uncontrolled glaucoma.

A 75-year-old man with underlying left eye idiopathic orbital inflammatory disease and bilateral glaucoma suspect with cup disc ratio 0.7 underwent right eye phacoemulsification. Intraoperatively, Descemet tear and Descemet membrane detachment (DMD) occurred. Pneumodescemetopexy with air bubble was performed. His vision remained counting fingers and the cornea was oedematous three weeks after the operation. Anterior segment optical coherence tomography (ASOCT) showed extensive (80%) rhegmatogenous DMD with planar edge and a maximum of 460 micrometers separation from the stroma. Pneumodescemetopexy with low concentration perfluoropropane (10% C3F8) was performed together with postoperative positioning. On day five post-pneumodescemetopexy, his vision improved to 6/9, the cornea cleared with mild Descemet striae, and the gas bubble reduced to 30% fill. There was no DMD detected on ASOCT. His vision remained 6/9 and the residual gas bubble was 15% in the anterior chamber at two weeks post-pneumodescemetopexy. This case report suggests that pneumodescemetopexy with 10% C3F8 successfully reattached the large nonplanar rhegmatogenous DMD.
Changes in organisation of instep kicking as a function of wearing compression and textured materials

This study investigated effects of wearing compression garments and textured insoles on modes of movement organisation emerging during performance of lower limb interceptive actions in association football. Participants were six skilled (age = 15.67 ± 0.74 years) and six less-skilled (age = 15.17 ± 1.1 years) football players. All participants performed 20 instep kicks with maximum velocity in four randomly organised insoles and socks conditions, (a) Smooth Socks with Smooth Insoles (SSSI); (b) Smooth Socks with Textured Insoles (SSTI); (c) Compression Socks with Smooth Insoles (CSSI); and (d), Compression Socks with Textured Insoles (CSTI). Results showed that, when wearing textured and compression materials (CSSI condition), less-skilled participants displayed significantly greater hip extension and flexion towards the ball contact phase, indicating larger ranges of motion in the kicking limb than in other conditions. Less-skilled participants also demonstrated greater variability in knee-ankle intralimb (angle-angle plots) coordination modes in the CSTI condition. Findings suggested that use of textured and compression materials increased attunement to somatosensory information from lower limb movement, to regulate performance of dynamic interceptive actions like kicking, especially in less-skilled individuals.
