After 4 weeks of enriched environment treatment, neurological deficits and neuronal death caused by middle cerebral artery occlusion/reperfusion were significantly alleviated, and infarct volume was significantly reduced. These findings suggest that neuronal autophagy is likely the neuroprotective mechanism by which an enriched environment promotes recovery from ischemic stroke. This study was approved by the Animal Ethics Committee of the Kunming University of Science and Technology, China (approval No. 5301002013855) on March 1, 2019.A growing body of evidence has suggested that the imbalance of epigenetic markers and oxidative stress appears to be involved in the pathophysiology and progression of stroke. Thus, strategies that modulate these biomarkers might be considered targets for neuroprotection and novel therapeutic opportunities for these patients. Physical exercise has been reported to induce changes in these epigenetic markers and improve clinical outcomes in different populations. However, little is reported on this in post-stroke patients. The purpose of this study was to investigate the effect of a single exercise session with WalkAide functional electrical stimulation (FES) on cognitive performance, clinical functional parameters, oxidative stress and epigenetic modulation in post-stroke individuals. In this crossover design study, 12 post-stroke individuals aged 54-72 years of either sexes were included and subjected to a single session of exercise (45 minutes) without WalkAide functional electrical stimulation (EXE alone gr group alone. In each group, both histone deacetylase (HDAC2) and histone acetyltransferase activities were increased after intervention compared with before the intervention. These findings suggest that a single exercise session with WalkAide FES is more effective on balance ability and cognitive performance compared with conventional exercise alone in post-stroke patients. This is likely to be related to the regulation of oxidative stress markers. The present study was approved by the Research Ethics Committee of the Methodist University Center-IPA (approval No. 2.423.376) on December 7, 2017 and registered in the Brazilian Registry of Clinical Trials-ReBEC (RBR-9phj2q) on February 11, 2019.We present an interesting case of a 58-year-old woman who presented coincident keratoconus and Fuchs' endothelial dystrophy. During the 7months following initial presentation, a decline in visual acuity was associated with an apparent improvement in keratoconus, as characterized by corneal tomography parameters, while an increase in corneal pachymetry was also observed. The patient has been managed with left endothelial keratoplasty. Selleck Biricodar This case poses the interesting question of how to classify coincident corneal disease, as traditional parameters for grading the severity of KC are altered by the presence of Fuchs' Endothelial Corneal Dystrophy and vice versa. In such cases, it is important to be aware of coincident disease to more accurately assess progression when considering treatment options and timing.Ocular trauma can range from trivial to significant, with varying implications on the visual acuity and prognosis. A 32-year-old woman presented with complaints of blurring of vision following blunt ocular trauma with a previous history of having undergone implantable phakic contact lens (IPCL V2.0) implantation 2 years back. The corrected distance visual acuity (CDVA) was 20/20 in the right eye and 20/30 in the left eye. Slit-lamp examination revealed a prolapse of inferonasal IPCL footplate into the anterior chamber with pupillary entrapment. No corneal endothelial touch was noted. Immediate repositioning of the IPCL was performed and the patient regained a CDVA of 20/20 in the left eye, postoperatively. Traumatic dislocation of IPCL is a rare occurrence, which can be successfully managed by prompt surgery, thus avoiding further complications like corneal endothelial decompensation.A young lady presented with very high vault and fixed dilated pupil along with optic capture of the implantable collamer lens (ICL). After thorough evaluation and ruling out the ICL sizing error, the optic capture was relieved and the ICL was rotated into vertical position. Single-pass four throw pupilloplasty was performed for the fixed dilated pupil. Postoperatively the ICL vault and the pupil size decreased and patient was asymptomatic. This case highlights a successful outcome of rotation of a nontoric ICL to reduce the high vaulting and optic capture along with single-pass four throw pupilloplasty.A 42-year-old female presented with pain, photophobia, and superficial corneal infiltrates in mid-periphery in the left eye, after 2 days of uneventful bilateral SMILE procedure. Inspite of the medical treatment with fortified antibiotics, the infection spread to the interface, close to visual axis reducing UDVA from 20/16 to 20/80. Immediate surgical intervention in the form of scraping of interface lesions with 26G needle, interface wash with antibiotics and photoactivated chromophore for keratitis (PACK-CXL) was performed. After 24 h of bacterial culture Staphylococcus aureus was yielded. Interface wash and PACK-CXL was repeated after 48 h by which infiltrates reduced and early scarring was observed by 10th post-op day. Subsequent topical steroids helped in limiting scar formation and UDVA improved to 20/30 at the final visit. Combined approach of interface wash with antibiotics and PACK-CXL may be a safe and effective modality in treating early onset infectious keratitis following SMILE surgery.A 27-year-old female patient came for a routine postoperative check-up, with a history of bilateral ReLEx small incision lenticule extraction (SMILE) surgery done 1.5 years back. On examination, epithelial ingrowth was noticed in the left eye at 8-9'o'clock position. Topography showed excess flattening in the area of ingrowth. Anterior Segment OCT showed hyper-reflectivity and was measured to be at a depth of 120 microns from the corneal surface. As the ingrowth appeared non-progressive, with no involvement of the pupillary axis and no visual complaints, no active intervention was done. Nonetheless, treatment options available include mechanical scraping and NdYAG laser procedure.A 24-year-old female underwent small incision lenticule extraction (SMILE) for myopic astigmatism OU. In the left eye, cap-lenticular adhesion along with tearing of the cap occurred, resulting in a gaped incision and transverse striae involving the visual axis on the first post op day. Uncorrected distance visual acuity (UDVA) was 20/32. The case was managed with interface wash and stretching of the cap, in order to iron out the striae. Post intervention, the UDVA improved to 20/20, striae resolved, and interface remained clear through a follow-up of nine months, suggesting that cap striae in SMILE may be similarly managed as the flap striae in laser-assisted in situ keratomileusis (LASIK), resulting in satisfactory visual outcomes.We report the clinical history and histopathology of the longest known postoperative course of a myopic cornea lenticule implanted via epikeratoplasty that also had been subjected to excimer laser and mitomycin. Despite the mechanical and photochemical processes the allogenic cornea stroma had sustained, it is notable that it retained structural integrity and clarity. This report affirms the potential long-term clarity and resilience of allogenic stromal cornea and supports its use as a potential stabilizing option in cornea allogenic intrastromal ring segments for keratoconus and variations thereof for other cornea disorders.A 25-year-old male patient presented with chief complaints of itching in both eyes (OU) for the past one month. Detailed ophthalmic examination showed best-corrected visual acuity of 6/6 OU. On slit-lamp examination of the left eye, Vogt's striae were documented and rest of the anterior segment was normal OU. Pentacam-HR and ASOCT confirmed the diagnosis of keratoconus. The patient was started on Trehalose containing preparation for both eyes. On follow-up visit at 8 months, progression was documented on Pentacam-HR. MS-39 showed epithelial remodeling, but no stromal or posterior elevation, indicative of a pseudo-progression. Corneal epithelial remodeling post topical trehalose containing eye drops application has been very sparsely reported in literature. It is an important differential to consider when faced with a situation of a likely progression of keratoconus, especially to differentiate true from pseudo-progression.A 23-year-old male presented to us wanting spectacle removal for cosmetic purposes. He underwent bilateral wavefront optimized (WFO) laser-assisted in situ keratomileusis (LASIK) on the Alcon Wavelight ® EX-500 excimer laser with an incorrectly treated astigmatism axis for left eye due to a manual data entry error in the laser. WFO LASIK treats the sphere and cylinder only. LASIK enhancement with topographic-guided ablation resulted in the elimination of all refractive errors and gave excellent results. Wavelight ® topographic-guided treatment can perform two separate layers of correction in the same ablation The first is to treat the corneal irregularities for the higher order aberration (HOA) removal, the second one meant to treat the sphere and cylinder if indicated.Recurrence of myopia after myopic LASIK reduces the outcome of the procedure. Important causes include post-LASIK ectasia, regression of myopia, accommodative strain, and lens or axial length changes. Herein, we present a case of myopia recurring after LASIK and try to arrive at the possible diagnosis among these, as the treatment differs for each. The detailed evaluation showed that our patient had regression of myopia after LASIK. Of the multiple causes for recurrence of refractive error after myopic laser vision correction, it is important to identify the relevant reason as the treatment and prognosis for each of these is different.A 28-year-old male underwent microkeratome assisted Laser-assisted in situ keratomileusis (LASIK) for, myopia. On postoperative day 1, patient had a large epithelial defect in OD. The corneal epithelial defect healed within 72 hours, but sub-optimal vision persisted. The patient was referred for further management to us. On evaluation, patient had non-healing of flap margin at 5 o'clock. Fluoroscein stain revealed no corneal epithelial defect, but a large pool of dye beneath the LASIK flap. A clinical diagnosis of non-adherence of LASIK flap was considered. Application of bandage contact lens was done. LASIK flap completely healed in 1 week. Possible etiologies are discussed and literature is reviewed.Transepithelial photorefractive keratectomy (tPRK) promotes faster re-epithelialization which in turn can reduce the risk of infectious keratitis in the postoperative period. We present a case of a 22-year-old man with infectious keratitis in his left eye 8 days after an uneventful bilateral tPRK. A 2 mm × 5 mm anterior stromal area of corneal infiltration with a same sized overlying epithelial defect was noted at the time of presentation. His uncorrected distance visual acuity was 20/63 in his left eye. Corneal scrapings showed Bordetella bronchiseptica. The infection responded to intensive treatment with topical levofloxacin 0.5% eye drops. The final visual acuity was 20/20 in the left eye.
