A rare case of a woman in her thirties with double optic disc pits involving opposing sectors is reported. Significantly decreased vision due to macular schisis was noted. Wide-field optical coherence tomography revealed distinct laminar defects and glial tufts associated with each pit. This case illustrates a rare view into the pathogenesis of optic disc pits.

The effects of actin dependent molecular mechanisms in coordinating cellular proliferation, migration and differentiation during embryogenesis are not well-understood. We have previously shown that actin-binding Filamin A (FlnA) and actin-nucleating Formin 2 (Fmn2) influence the development of the brain causing microcephaly in mice. In this study, we broaden this phenotype to explore the effects of these two proteins in the development of extra-CNS organ systems, including the gut, muscle, and skeleton. We observed defects in rib and sternum midline closure leading to thoracoabdominal schisis in FlnA+Fmn2 knockout mice, reminiscent of the pentalogy of Cantrell syndrome...

X-linked juvenile retinoschisis is a hereditary disorder which usually occurs in boys rather than in girls, who are rarely affected. First clinical manifestations usually appear during the first decade. It is responsible for variable severity and slowly progressive vision loss. This progression can be characterized by vitreous hemorrhages and recurrent retinal detachments. We report the case of a 17-year old patient with stellar bilateral microcistic macular rearrangement of the eye-ground, centered on the foveola, associated with peripheral schisis with retinal detachment and unilateral tearing of internal and external layers...

BACKGROUND: The pathogenesis of non-rhegmatogenous retinal detachment (non-RRD) associated with morning glory syndrome (MGS) is not established, as well as best surgical approach to treat RD. Our purpose was to analyse intraoperative optical coherence tomography data (iOCT) in all steps of pars plana vitrectomy (PPV) for non-RRD in MGS, in order to follow pathophysiological aspects of the disease and to understand the tissues behaviour during surgical workflow. CASE PRESENTATION: Intraoperative spectral domain optical coherent tomography (iSD-OCT) assisted PPV using Rescan 700 (Carl Zeiss Meditech, Jena, Germany) with epiretinal membrane (ERM) and internal retinal membrane (ILM) peeling, and air endotamponade was performed on the only eye of a 21 years old female with non-RRD associated with MGS...

INTRODUCTION: Congenital variants of the cervical spine may mimic traumatic lesions and may cause recurrent episodes of pain. The spectrum of cervical variants includes persistent apophyses of the transverse processes, persistent epiphyses, vertebral platyspondylia, vertebral hypoplasia, and dysplasia of the vertebral arch. Furthermore, abnormalities of the spinous process have been described including doubled spinous processes and hypertrophies. Unilateral hyperplasia of a spinous process is a rare finding that has only been described rarely as case reports...

Herein, we report the case of an 8-year-old girl who presented in December 2000 with a submacular neovascular membrane in the right eye, with a clinical diagnosis of Best disease. At that time, she underwent pars plana vitrectomy (PPV) with removal of the subretinal choroidal neovascularization (CNV). Her vision improved from 20/200 to 20/25. Four years later, a new CNV developed in the other eye. Initially, she underwent unsuccessful photodynamic therapy. As her vision worsened, she underwent a second, this time successful, PPV with membrane removal in the left eye, with vision improving to 20/30...

BACKGROUND: X-linked retinoschisis (XLRS) is a vitreoretinal degenerative disorder causing vision deterioration, due to structural defects in retina. The hallmark of this disease includes radial streaks arising from the fovea and splitting of inner retinal layers (schisis). Although these retinal changes are attributed to mutations in the retinoschisin gene, schisis is also observed in patients who do not carry mutations. In addition, the origin of intraschisis fluid, the triggering point of schisis formation and its progression are largely unknown still...

We present the three-dimensional (3D) spectral-domain optical coherence tomography (SD-OCT) findings of schisis-like maculopathy associated with structural changes of the optic nerve (ON) head as well as the treatment outcomes of a case of advanced glaucoma. In addition to ophthalmological examination, B-scan and 3D-SD-OCT images of the ON head, peripapillary retina, and the macula were obtained. The B-scan images only detected typical retinoschisis findings. However, the 3D-SD-OCT images of the ON head revealed defects of various sizes, shapes, and depths at the outer wall of the prelaminar and laminar regions of the ON canal...

BACKGROUND: X-linked Retinoschisis (XLRS) is one of the most common macular degenerations in young males, with a worldwide prevalence ranging from 1:5000 to 1:20000. Clinical diagnosis of XLRS can be challenging due to the highly variable phenotypic presentation and limited correlation has been identified between mutation type and disease severity or progression. CASE PRESENTATION: We report the atypical early onset of XLRS in 3-month-old monozygotic twins. Fundus examination was characterized by severe bullous retinal schisis with pre-retinal and intraretinal haemorrhages...
