Filter by:Many patients will have underlying maculopathy present when undergoing cataract surgery, which are not visible on fundoscopy alone. Knowledge of this underlying pathology will allow an improved consenting process and discussion with the patient regarding the risks, visual prognosis and recovery following cataract surgery. Incidental findings in the fellow eye would also allow for improved diagnosis and management of these patients without adding significant additional time to specialist high volume cataract assessment clinics.
As technology advances, vitrectomy cutters are smaller and cut rates have become faster. In this prospective study, the vitrectomy efficiency and safety between 5,000 cuts per minute with 10,000 cuts per minute are compared
Macular hole surgery were tried by different surgeons using many techniques with different successes but still there were many recurrences. In this study the investigators try to close these distinct types including recurrent holes using pre-prepared amniotic membrane.
Since 1991, idiopathic macular holes (MH) can benefit from an effective treatment initially involving pars plana vitrectomy, stripping of epiretinal membranes and intraocular gas tamponade followed by facedown positioning. The initial 58% success rate has further increased to 85-100% with internal limiting membrane (ILM) peeling. However, complete ILM removal has been shown to lead to anatomic changes causing the retina to have the appearance of a dissociated optic nerve fiber layer (DONFL). Moreover, it has been associated with decreased retinal sensitivity that may cause visual discomfort despite good visual acuity. Nawrocki et al. recently suggested to reduce the area of peeled ILM (temporal inverted ILM flap technique) in order to minimize iatrogenic trauma while maintaining satisfactory surgical outcomes. The aim of this study is to compare the incidence of DONFL appearance and retinal sensitivity after macular hole surgery in eyes that underwent temporal inverted ILM flap technique and eyes that had complete ILM peeling
Since the introduction of vitrectomy in 1971, this procedure has become the third most frequently performed ophthalmic surgery. Approximately 225,000 vitrectomies are performed annually in the United States and indications continue to expand. Known long-term complications of vitrectomy are relatively few and include retinal detachment and cataract formation. Although much has been written in the literature concerning acute rises in intraocular pressure (IOP) in the immediate postoperative period, there is surprisingly little information on long term IOP outcomes after vitrectomy. A recent report by Chang given at the LXII (62) Edward Jackson Memorial Lecture hypothesized a causal relationship between vitrectomy and open-angle glaucoma (OAG) via oxidative stress exacerbated by removal of the crystalline lens. A second report by Luk and colleagues reported similar conclusions in a modified cohort. Both studies, were retrospective in nature and did not perform baseline evaluations to exclude pre-existing glaucoma. Furthermore neither study accounted for natural history. Finally, our analysis has not reproduced similar results. The primary purpose of this study is to analyze the full spectrum of optic nerve and macular changes between vitrectomized study eyes and their non-vitrectomized fellow eyes to control for natural history. Baseline evaluations will include examination by fellowship trained retina and glaucoma specialists, fundus photography, autofluorescence, optical coherence tomography (macula and optic nerve) and automated visual field testing. At 3 month then annually for 5 years after vitrectomy surgery, the cohort will undergo similar evaluation.
