Filter by:A Retrospective Review of Pain and Inflammation Resolution Outcomes in Patients Who Received DEXTENZA Intracanalicular Dexamethasone (0.4 mg) Insert Prior to or Following Corneal transplant or Cataract surgery
Assessing the efficacy and safety of DEXTENZA, sustained release dexamethasone 0.4 mg insert following corneal transplant surgery (PKP, DSEK, DMEK) as compared to topical prednisolone acetate 1%.
Ophthalmology ,cornea Autologous serum has long been known to be effective to promote corneal epithelial wound healing in a variety of ocular surface disorders. However, its effectiveness for corneal epithelial defects due to pars plana vitrectomy (PPV) for diabetic retinopathy and penetrating keratoplasty has seldom been reported. In this study, we plan to perform a prospective study to determine the effectiveness of topical autologous serum as a primary treatment for corneal epithelial defect in patients undergoing vitrectomy for diabetic retinopathy and penetrating keratoplasty. All patients enrolled in this study have received corneal epithelial debridement at the end of the ocular surgeries, namely PPV for diabetic retinopathy and penetrating keratoplasty. The patients were grouped into two treatment groups. In the control group, the patients receive conventional postoperative eye drops including topical steroid, antibiotic and mydriatics. In the experimental group, the patients receive topical autologous serum eye drops in addition to conventional postoperative eye drops. The duration for cornea surface to completely re-epithelize, the incidence of corneal complications due to delayed surface re-epithelization (e.g. infectious corneal ulcer, corneal melting, sterile corneal ulcer, corneal neovascularization), and the incidence of recurrent epithelial break down after initial epithelization will be compared between these two groups. Patients undergoing PPV for diabetic retinopathy and penetrating keratoplasty will be compared separately
1. Purpose:Our animal study demonstrated the effectiveness of subconjunctival injection of bevacizumab in the inhibition of corneal neovasculization formation. The purpose of this human interventional study is to report the treatment outcome of subconjunctival injection of bevacizumab in patients with corneal neovascularization. 2. Material and methods: We enrolled 13 patients with unilateral or bilateral clinically significant corneal neovascularization during Aug. 2007 to Jan. 2008. Subconjunctival injection of bevacizumab once per month for at most 7 times was performed according to clinical response. 3. Main outcome measurements: resolution of corneal neovascularization, reduction of lipid infiltrate, improved visual acuity.
