Sterile corneal necrosis after bowman layer transplantation by Ana Orive Bañuelos
Purpose: To report sterile corneal necrosis as a severe and rare complication after Bowman Layer Transplantation (BTL). Methods: A 35-year-old woman with Down syndrome and advanced progressive keratoconus in her left eye was scheduled for a BLT. The patient rubbed her eyes and did not tolerate contact lenses. Following standard technique, a 8mm Bowman layer…
Optimal Calculation of Mean Pressure from Pulse Pressure by Liam Y H Tien
CONCLUSIONS: Our study suggests that all current formulae are adequate for estimating MAP, though some formulae are not suitable for mean IOP and JVP.
Likelihood of spontaneous closure of cavernous sinus dural arteriovenous fistulas based on clinical and radiological findings by Roy Tan
CONCLUSIONS: In our study, 52% of CSDAVF closed spontaneously. As deterioration of ocular symptoms in patients with CSDAVF might also reflect spontaneous progressive occlusion, it warrants dynamic vascular imaging to check the status of venous outflow. Patients with CSDAVF with corticovenous reflux or deterioration of visual acuity need more urgent (endovascular) treatment.
Primary versus secondary intraocular lens implantation following removal of congenital/de al of congenital/developmental catar elopmental cataracts: outcomes after acts: outcomes after at least 4 years by Ayşin Tuba Kaplan
BACKGROUND: The aim of this study is to evaluate the long-term outcomes of primary and secondary intraocular lens (IOL) implantation following removal of congenital/developmental cataracts.
What Is a Preferred Retinal Locus? by Luminita Tarita-Nistor
This review examines the concept of the preferred retinal locus (PRL) in patients with macular diseases. Considering monocular and binocular viewing, we (a) explain how to identify the PRL and discuss the pitfalls associated with its measurement, (b) review the current hypotheses for PRL development, (c) assess whether the PRL is the new reference point…
The effect of lncRNA ADPGK-AS1 on the proliferation and apoptosis of retinoblastoma cells by targeting miR-200b-5p by F Xing
Objective: To explore the effect of lncRNA ADPGK-AS1 on the proliferation and apoptosis of retinoblastoma cells and its possible mechanism. Methods: The tumor tissues of 31 patients with retinoblastoma admitted to Henan Provincial Eye Hospital from February to June 2020 and their corresponding normal tissues adjacent to the cancer were collected. The expression levels of…
Ultrasound-Guided Transcutaneous Injection in the Lacrimal Gland: A Description of Sonoanatomy and Technique by Ann-Cathrine Larsen
Purpose: To develop a method of injecting a volume up to 50% of the lacrimal gland (LG) volume while minimizing patient discomfort and maximizing accurate drug delivery. Herein we describe a series of ultrasound (US)-guided transcutaneous injections in the LG and discuss the safety and feasibility of this technique. Methods: Ultrasonography was performed in 40…
Cardiovascular Safety in Type 2 Diabetes With Sulfonylureas as Second-Line Drugs: A Nation-Wide Population-Based Comparative Safety Study by Huan Wang
CONCLUSIONS: Our findings contribute to the understanding that second-line SU for glucose lowering are unlikely to increase CV risk or all-cause mortality. Given their potent efficacy, microvascular benefits, cost effectiveness, and widespread use, this study supports that SU should remain a part of the global diabetes treatment portfolio.
Peroxisome proliferator-activated receptor-α (PPARα) regulates wound healing and mitochondrial metabolism in the cornea by Wentao Liang
Diabetes can result in impaired corneal wound healing. Mitochondrial dysfunction plays an important role in diabetic complications. However, the regulation of mitochondria function in the diabetic cornea and its impacts on wound healing remain elusive. The present study aimed to explore the molecular basis for the disturbed mitochondrial metabolism and subsequent wound healing impairment in…
Internalization of Angiotensin-(1-12) in Adult Retinal Pigment Epithelial-19 Cells by Sarfaraz Ahmad
Purpose: Angiotensin-(1-12) [Ang-(1-12)] serves as a primary substrate to generate angiotensin II (Ang II) by angiotensin-converting enzyme and/or chymase suggests it may be an unrecognized source of Ang II-mediated microvascular complication in hypertension-mediated retinopathy. We investigated Ang-(1-12) expression and internalization in adult retinal pigment epithelial-19 (ARPE-19) cultured cells. We performed the internalization of Ang-(1-12) in…
