AIM: Posterior vitreous detachment (PVD) is a physiological phenomenon due to aging characterized by separation of the vitreous cortex from the retina and may induce a variety of pathological events at the vitreoretinal junction. The aim of this study is to highlight in vivo anatomical and functional changes in early stages of PVD allowing the correct treatment. MATERIAL AND METHODS: Non-consecutive case series; optical coherence tomography (OCT) relies on analyzing the reflectivity of coherent light from different anatomical interfaces within posterior vitreous and retinal histological layers, thus acquiring transverse sections through vitreoretinal interface, sensory retina, retinal pigment epithelium and choroid...

PURPOSE: Macular pucker (MP) and macular hole (MH) are vitreomaculopathies treated by vitrectomy and membrane peel. The complication of postoperative central scotoma can be associated with significant reduction in visual acuity (VA). We seek to determine whether retinal nerve fiber layer (RNFL) disruption is the pathophysiologic basis of this defect. Mitigating clinical circumstances also were sought. METHODS: Eleven eyes from 10 pseudophakic patients who had undergone vitrectomy with peeling for either MH or MP were studied with clinical measures, including optical coherence tomography (OCT)...

OBJECTIVES: Vitreoschisis is a possible pathogenic mechanism in macular diseases. Thus, the vitreoretinal interface was evaluated in monkey eyes and patients with various macular diseases in search of vitreoschisis. It is hypothesised that vitreoschisis is present in macular holes (MH) and macular pucker (MP), but not in other maculopathies. METHODS: Histopathology was studied in 14 monkey eyes and a vitrectomy specimen of a patient with macular pucker. Optical coherence tomography/scanning laser ophthalmoscopy (OCT/SLO) was performed in 239 eyes: 45 MH, 45 MP, 51 dry age-related macular degeneration (AMD), 53 non-proliferative diabetic retinopathy (NPDR) and 45 controls...

BACKGROUND: To date, the surgical plan for the removal of epiretinal membranes is mainly adapted to the intraoperative situation. In the current study, we sought to investigate whether the surgical removal of macular pucker can be facilitated by the preoperative assessment of topographic features using high-definition optical coherence tomography (HD-OCT). PATIENTS AND METHODS: In a consecutive case series, 20 eyes of 20 patients with macular pucker underwent full ophthalmological evaluation including high-definition optical coherence tomography (Cirrus, Carl Zeiss Meditec) prior to a three-port-pars plana vitrectomy with peel of the epiretinal membrane (ERM)...

PURPOSE: Vitreo-macular pathology may be influenced by vitreo-papillary adhesion (VPA). Optical coherence tomography/scanning laser ophthalmoscopy (OCT/SLO) was used to identify VPA in full-thickness macular hole, lamellar hole, and macular pucker (MP). METHODS: Ultrasonography and OCT/SLO were performed in 55 subjects: 16 with macular hole, 11 with lamellar hole, and 28 with MP. The main outcome measures were the presence of posterior vitreous detachment by ultrasound, and the findings of VPA and intraretinal cysts by OCT/SLO...

J Petersen, U Ritzau-Tondrow, H Hoerauf
BACKGROUND: The latest development in ARMD surgery is the translocation of an autologeous pigment epithelium choroid patch. The method has technical shortcomings: The transplant is excised including the overlaying retina and inserted through a retinotomy near the posterior pole thus causing iatrogenic field defects. For the same reasons the size of the transplant is limited. MATERIALS AND METHODS: The technique was modified as follows: lens surgery using a special PCL with equal power in water and silicone oil, 180 degrees retinotomy just at the temporal ora serrata, subretinal surgery including patch transplantation with the retina folded over nasally and fixed by PFCL, complete silicone oil tamponade without any water remaining...

Epimacular membrane (ERM) formation is an age-dependent more or less vision-threatening finding. Increased life expectancy and patient demand for better vision have led to increasing numbers of patients seeking therapy, making selection for surgery mandatory. The impressive improvements in macular hole surgery have influenced the epiretinal membrane and have renewed its therapeutic approach. Disturbing metamorphopsia, visual deterioration under 5/10, especially near-vision alteration and binocular disturbance, are major symptoms to motivate surgery...
