Purpose: To report the case of an adult male with X-linked retinoschisis (XLRS) who presented with cystoid macular edema (CME) that responded consistently to treatment with intravitreal steroids. Observations: A 39 year old male with unilateral presentation of CME after repair of a retinal detachment secondary to XLRS responded initially to an injection of intravitreal triamcinolone acetonide (IVTA). Central subfield thickness on OCT was reduced. Three months later, the CME recurred and he was unresponsive to topical treatment so repeat IVTA was given, and the CME once again was reduced dramatically...

The quality of care for patients with cleft lip and palate is extremely variable across the world. Treatment protocols differ and methods of data registration are not uniform. Improving this care by means of comparative research is challenging. The best treatment programmes can be identified by uniformly registering patient-orientated outcomes and comparing the outcomes with those of other treatment centres. That knowledge can be used to improve one's own care. An international team consisting of specialists and cleft lip and palate patients has developed a set of outcome measures that are considered by patients to be most important...

An 11-year-old boy presented for central vision blurring in each eye. Visual acuity was 20/80 and examination revealed spoke-wheel foveal schisis and peripheral elevated diaphanous inner retina in each eye. Spectral-domain optical coherence tomography showed inner-retinal, flat-topped cysts in each eye. Electrophysiologic testing was refused, but a clinical diagnosis of X-linked retinoschisis was made. Three months after topical dorzolamide (Trusopt; Santen Pharmaceutical, Osaka, Japan) was started, the macular cysts worsened significantly...

True exfoliation syndrome (TEX, capsular delamination or schisis) is a unique condition in which characteristic lamellar separation of the anterior lens capsule occurs. Because the delaminated membrane is remarkably thin and translucent, and initial detachment occurs peripherally along the zonular insertions, the condition tends to be overlooked on routine examination with inadequate mydriasis. The condition increases with age and despite the classic association with occupations involving intense heat, most cases are idiopathic...

BACKGROUND: Peripapillary intrachoroidal cavitation was described as the presence of an asymptomatic, well-circumscribed, yellow-orange, peripapillary lesion at the inferior border of the myopic conus in eyes with high myopia. CASE PRESENTATION: A 66-year-old myopic Chinese man was enrolled and his multi-color imaging examination showed a well-circumscribed, caesious, peripapillary lesion coalesced with the optic nerve head vertically rotated and obliquely tilted, together with an inferotemporal sinkhole in the myopic conus...

Enhanced S-cone syndrome (ESCS) is mainly associated with mutations in the NR2E3 gene. However, rare mutations in the NRL gene have been reported in patients with ESCS. We report on an ESCS phenotype in additional patients with autosomal recessive NRL (arNRL) mutations. Three Moroccan patients of two different families with arNRL mutations were enrolled in this study. The mutation in the DNA of one patient, from a consanguineous marriage, was detected by homozygosity mapping. The mutation in the DNA of two siblings from a second family was detected in a targeted next-generation sequencing project...

We present a case in which a large, bullous, predominantly inferior, serous retinal detachment developed acutely after the Valsalva manoeuvre (from a coughing fit) in an eye with morning glory disc anomaly. We postulate that a rapid alteration in intracranial pressure was transmitted through the cavitary disc defect. This allowed a sudden influx of cerebrospinal fluid and/or liquefied vitreous into the subretinal space. This previously unreported case provides important evidence for the role of intracranial pressure fluctuations in the pathogenesis of macular schisis and neurosensory detachment secondary to optic disc cavitations...

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...
