Summary: PQ-504a-001 (Fuchs Focus) is an open-label, single-dose, exploratory study to evaluate safety, tolerability, and corneal endothelium molecular biomarker(s) in subjects with Fuchs Endothelial Corneal Dystrophy with Trinucleotide Repeat Expansion in the TCF4 gene (FECD3).
Summary: Primary Objectives: To evaluate the safety of The Gene Replacement Therapy by rAAV2/8-hCYP4V2 Following a Single Subretinal Administration in The Patients of Bietti's Crystalline Dystrophy (BCD).Secondary Objectives: To explore the efficacy of The Gene Replacement Therapy by rAAV2/8-hCYP4V2.
Summary: This will be a prospective assessment of whether adjuvant Netarsudil use in patients undergoing Descemetorhexis without endothelial keratoplasty improves time to corneal clearance and post-operative central endothelial cell counts. The anticipated enrollment is 25 patients.
Summary: This study aims to evaluate and compare incidence of post-operative cystoid macular edema (CME) after Descemet Membrane Endothelial Keratoplasty (DMEK), Descemet's Stripping Automated endothelial Keratoplasty (DSEK) and Descemet Stripping Only (DSO).
Summary: The purpose of this study is to determine the difference in the cornea's response to contact lens placement between healthy and unhealthy eyes. The amount of corneal swelling (corneal thickness) between normal and FECD patients before and after a stress test will be measured and compared.
Summary: This is an observational study using optical coherence tomography (OCT) technology to quantify corneal edema in Fuchs' endothelial dystrophy and predict refractive shift from resolving corneal edema after surgical treatments.
Summary: Knowledge of the pathogenesis of ocular conditions, a leading cause of blindness, has benefited greatly from recent advances in ophthalmic imaging. However, current clinical imaging systems are limited in resolution, speed, or access to certain structures of the eye.The use of a high-resolution imaging system improves the resolution of ophthalmoscopes by several orders of magnitude, allowing the v...
