BACKGROUND: Previous studies have shown promising effects of combining intravitreal bevacizumab and suprachoroidal injection of triamcinolone acetonide in treating DME. However, further research is needed. OBJECTIVE: To assess the efficacy and safety of combining both intravitreal Ziv-aflibercept and suprachoroidal injection of triamcinolone acetonide using a custom-made needle in naïve and de novo central diabetic macular edema (DME) patients every eight weeks for 24 weeks...

Persistent fetal vasculature is a spectrum of ocular abnormalities linked to an incomplete regression of the fetal ocular vasculature. A 21-years old male patient came to the outpatient clinic reporting low vision and strabismus in his left eye since 3 years of age. Ophtalmological examination revealed a normal right eye, while the left eye had a best corrected visual acuity of hand-motion perception, a 30 prism diopters esotropia, a "coralliform" cataract and a vitreous stalk joining the posterior face of the lens and the optic nerve...

BACKGROUND: The COVID-19 pandemic had a profound impact on healthcare and ophthalmology services globally. Numerous studies amongst various medical and surgical specialties showed a reduction in patient attendance and surgical procedures performed. Prior published ophthalmic literature focused on specific types of procedures and were usually single centre. The current study attempts to quantify the impact on a larger scale, namely that of sub-Saharan Africa, and to include all ophthalmic subspecialties...

METHODS: Retrospective analysis of 120 diabetic patients who underwent PPV or PPVCE. RESULTS: The key outcome indicators were best-corrected visual acuity (BCVA) and post-operative complications. The PPVCE group had an average age of 53 years, with 50% females and 50% males...

Microperimetry is an emerging technology that provides concurrent analysis of retinal structure and function by combining retinal sensitivity and fixation analysis with fundus imaging. We summarize the substantial evidence validating the evolving role of microperimetry as an adjunctive assessment of visual function in the perioperative setting. We show that microperimetry provides useful complementary information to other established imaging and functional modalities in the perioperative setting for a wide range of vitreoretinal surgical procedures, as well as in cataract and refractive surgeries...

PURPOSE: Selecting an anesthetic agent for ophthalmic surgery has crucial implications for the surgeon, anesthesiologist, and patient. This educational review explores the common classes of anesthesia used in ophthalmology. Additionally, we discuss the considerations unique to cataract, glaucoma, strabismus, orbital, oculoplastic, and ocular trauma surgeries. METHODS: A comprehensive Embase search was performed using combinations of the subject headings "anesthesia", "eye surgery", "ophthalmology" and "cataract extraction", "glaucoma", "strabismus", "vitreoretinal surgery", "retina surgery", "eye injury", and "eyelid reconstruction"...

OBJECTIVES: The weakness and dialysis of lens zonule after cataract surgery may lead to dislocation of intraocular lens (IOL). It has been shown that cataract surgery could induce or aggravate posterior vitreous detachment (PVD) due to postoperative inflammation and increased volume of vitreous cavity. PVD is associated with the occurrence of several vitreoretinal diseases, such as rhegmatogenous retinal detachment and macular hole. This study aims to explore risk factors for dislocation of IOL concurring with vitreoretinal disease, such as retinal detachment and macular hole, and to evaluate the efficacy and complications of surgical intervention for these abnormalities concurrently...

PURPOSE: To evaluate the refractive outcomes of combined cataract surgery and vitrectomy to cataract surgery alone. METHODS: This retrospective chart review study included two groups - 1) combined surgery in 103 eyes (101 patients) who underwent cataract surgery with posterior chamber intraocular lens (PCIOL) placement by a single cataract surgeon and vitrectomy by a single vitreoretinal surgeon at the same surgical setting 2) cataract surgery alone by the same surgeon in 107 eyes (84 patients)...

Background: Intraocular foreign body (IOFB) removal becomes tricky if its large and impacted in the ocular coats. When confronted with such a combination, the vitreoretinal surgeon will need to modify the surgical plan. This surgical video describes one of such situation encountered during removal of a long wooden IOFB impacted in the ocular coats. Purpose: The video describes a scenario when the surgeon becomes aware that injury to ocular structure is inevitable due to inherent length of the IOFB...

PURPOSE: An increasing number of posterior segment disorders is routinely managed with pars plana vitrectomy (PPV). In older, phakic patients cataract formation is expected within the first two years after surgery. For younger patients its progression is individually fluctuating. This study uses an objective quantitative measurement for lens-status-monitoring after PPV with silicone oil to derive predictions for progression and severity of post-operative lens opacification evaluated in patients with rhegmatogenous retinal detachment (RRD)...

To investigate changes in the corneal shape caused by fluid-gas exchange after vitrectomy.This retrospective case-control study included 43 eyes that underwent a combination of cataract surgery and vitrectomy. The corneal shape was measured using anterior segment optical coherence tomography CASIA2. The corneal shape measurements were performed preoperatively, 1 day, 1 week, 1 month, and 3 months after surgery. After calculating the real K value from the actual measured values of the posterior shape of the corneal refracting power and the single posterior corneal refracting power value, Fourier analysis values were examined...
