Article Synopsis
- The study evaluates the long-term effectiveness of pars plana vitrectomy (PPV) in patients with intraocular foreign bodies (IOFB) from gunshot injuries, focusing on visual outcomes and complications.
- Out of 103 patients, the mean initial visual acuity was low, but 58.2% saw improvement after surgery, with some achieving significant vision gains; however, complications mainly stemmed from the original injuries.
- Overall, PPV showed promising results for visual recovery and globe survival, though poor initial vision and specific injury characteristics were linked to worse final vision outcomes.
Objective: To evaluate the risks that might be associated with recurrent macular hole retinal detachment (MHRD) after silicone oil (S.O) removal in myopic patients with open flat macular hole (MH).
Methods: In this retrospective series, we assessed the different factors that might be associated with recurrent MHRD after S.
Purpose: To assess the roles of oxidative stress and vascular endothelial growth factor (VEGF) in pterygium pathogenesis and prevention of pterygium recurrence after surgical excision.
Methods: Surgically removed pterygium tissue from 35 pterygium patients and normal conjunctival samples from 15 patients matched for age and sex (used as controls) constituted the study samples. The conjunctival samples were preserved at - 80 °C until analysis.
Purpose: To report the long-term follow-up of patients with inadvertent retained submacular perfluorocarbon liquid (PFCL) bubbles after vitrectomy surgery.
Background: PFCL has unique chemical and physical features which facilitate displacement of subretinal fluid from central toward periphery allowing intraoperative reattachment of the mobile retina and manipulation of the anterior part of the detached retina without performing drainage retinotomy. Despite these advantages, PFCL droplets may be inadvertently retained in the submacular space.
Anatomical and Functional Retinal Complications of Combined Sofosbuvir and Ribavirin Therapy in Patients With Chronic Hepatitis C Virus.
Ophthalmic Surg Lasers Imaging Retina
January 2019
Background And Objective: To evaluate the anatomical and functional retinal complications of combined sofosbuvir and ribavirin therapy in patients with chronic hepatitis C virus (HCV).
Patients And Methods: Three hundred patients with chronic HCV were recruited for this prospective, observational study from the National Liver Institute of Menoufia University from November 2015 to September 2017. Ophthalmic examination and follow-up were performed in the outpatient clinic of the Ophthalmology Department at Menoufia University.
Safety of high-dose intravitreal triamcinolone acetonide as low-cost alternative to anti-vascular endothelial growth factor agents in lower-middle-income countries.
Clin Ophthalmol
November 2018
Purpose: The purpose of this study was to evaluate the safety of high-dose intravitreal triamcinolone acetonide (IVTA) as affordable low-cost alternative to anti-vascular endothelial growth factor (anti-vascular endothelial growth factor [anti-VEGF] agents) in lower-middle-income countries.
Patients And Methods: This was a retrospective interventional non-comparative case series. The study recruited patients who received 20 mg IVTA for treating various retinal and optic nerve diseases over the past 5 years.
Objective: The aim of this study is to compare subfoveal choroidal thickness (SFCT) before and after uneventful phacoemulsification using enhanced depth imaging optical coherence tomography (EDI-OCT).
Background: Cataract is a major cause of visual impairment in the elderly. Cataract surgery is the most common ophthalmic surgery and is performed simultaneously with glaucoma or vitreous surgery in many cases.
Safety of Silicone Oil Removal in Cases of Gunshot Perforating Eye Injuries.
Ophthalmic Surg Lasers Imaging Retina
March 2017
Background And Objective: To evaluate the feasibility and safety of silicone oil (SO) removal in cases of gunshot perforating eye injuries (PEI).
Patients And Methods: A retrospective, consecutive, interventional study from medical records regarding cases of gunshot PEI during the periods of Egyptian political instability (January 2011 until December 2013). The main outcomes were to evaluate the feasibility of SO removal in cases of gunshot PEI and management of retinal detachment (RD) after SO removal in such cases.
Purpose. To evaluate the efficacy of silicone oil (S.O) reinjection without macular buckling for treatment of recurrent myopic macular hole retinal detachment (MHRD) after silicone oil removal.
