Filter by:It has been hypothesized that potential effects of laser Nd: YAG laser posterior capsulotomy may affect macular pigment as well as choroidal thickness, macular thickness and anterior chamber parameters, so it was aimed to investigate possible effects of Nd: YAG laser posterior capsulotomy on macular pigment optical density, choroidal thickness, macular thickness and anterior chamber parameters in cases with posterior capsule opacification in this study.
Photoreceptor apoptosis is the basis for permanent visual loss in a number of retinal disorders including age-related macular degeneration (AMD) and retinal detachment (RD). Thus, despite tremendous advances in vitreoretinal surgery and management of rhegmatogenous RD leading to a primary reattachment rate over 95%, some patients show poor visual recovery because of photoreceptor apoptosis. Physiologically, microglial cells (resident macrophages) are present only in the inner retina. The subretinal space, located between the retinal pigment epithelium (RPE) and the photoreceptor outer segments (POS), is devoid of all mononuclear phagocytes and form a zone of immune privilege. In AMD, several studies showed a strong association between subretinal mononuclear phagocytes infiltration and advanced forms of AMD. Experimental work in mice suggest that this infiltration plays an important role in the pathogenesis of this condition by producing inflammatory cytokines. RD-induced photoreceptor apoptosis might result from similar mechanisms. The aim of this study is to determine the cytokine profile in vitreous samples from patients with RD and to compare it with those from control patients with macular hole.
We reviewed the records of 120 consecutive patients (male and female), aged 85 years and above, who underwent pars plana vitrecromy in the Tel Aviv Medical Center during the years 01/01/2006 - 31/12/2013, and were followed by physicians in the ophthalmology department in the center until December 2015.
The investigators compared the incidence of trimming-induced retinal breaks, retinal redetachment rate, and final LogMAR BCVA; between scleral self-indentation and non-indentation during chandelier-assisted peripheral vitrectomy under air for eyes with primary retinal detachment. Self-indentation enables complete trimming of the vitreous base without causing iatrogenic retinal breaks, with a higher retinal reattachment rate, and with less need for chandelier shift than with non-indentation approach.
The aim of this study is to report outcomes of pars plana vitrectomy (PPV) in pediatric retinal detachment (RD) accompanied with proliferative vitreoretinopathy (PVR) as well as complications and factors influencing the final anatomical and functional results. This is retrospective consecutive case series of 14 eyes treated with primary PPV for RD repair. Average postoperative follow-up period is 34 months.
Individuals operated for rhegmatogenous retinal detachment will be prospectively evaluated for postoperative retinal shift. Fundus autofluorescence will be used to evaluate retinal shift that will be correlated to visual acuity, metamorphopsia, aniseikonia, and stereopsis.
From July 2015 to December 2015, clinical record of 8 consecutive cases of macular hole with retinal detachment in high myopia treated with combined inverted and free ILM flap insertion into the hole were retrospectively reviewed. The anatomical and function outcomes were assessed.
The study is collecting data along with other academic institutions regarding the accuracy of ocular ultrasound in diagnosing retinal detachment.
The study aimed to investigate the effectivity of bupivacaine 0,5% as post-operative analgesia in intravitreal silicone evacutaion surgery
Silicone oil has been used as a surgical tool in complicated retinal detachment surgery. There are some complications occurring in pars plana vitrectomy with silicone oil tamponade. Silicone oil emulsification is one of the complication that may result in severe sequels that are difficult to treat. It is believed that low viscosity silicone oil has more risk to develop emulsification than high viscosity silicone oil. Up to now, however, there is no conclusive guideline that which types of silicone oil is suitable for these complicated retinal detachment surgeries and what is the appropriate time to remove the oil. This prospective study aims to study the silicone oil emulsification comparing between low viscosity and high viscosity silicone oil after complicated retinal detachment surgery.
