Kara Murias, Andrea Moir, Kenneth Alexis Myers, Irene Liu, Xing-Chang Wei
AIM: To summarize the reported rates of magnetic resonance imaging (MRI) abnormalities in children with isolated global developmental delay (GDD) or intellectual disability (ID). METHOD: A literature search was conducted using electronic databases for studies reporting the rate of MRI abnormalities in children with clinically diagnosed ID or GDD and no other neurological signs, symptoms, or previously determined aetiology. All investigations with participants from birth to 18years were considered...

IMPORTANCE: This study provides results of a treatment option for patients with failed primary glaucoma drainage device BACKGROUND: To describe and evaluate the long term intraocular pressure (IOP) control and complications of a new technique joining a second glaucoma drainage device (GDD) directly to an existing GDD: termed "piggyback drainage". DESIGN: A retrospective, interventional cohort study PARTICIPANTS: 18 eyes of 17 patients who underwent piggyback drainage between 2004 and 2013 inclusive...

AIM: To explore the association between social disadvantage and developmental diagnoses in pre-school children. METHODS: Between 2012 and 2015, 845 pre-school children were assessed by the Child Assessment Team at Campbelltown Hospital. A social worker interviewed 469 families and these children were eligible for inclusion in the study. Autism spectrum disorder (ASD) was confirmed in 290 children. Of those without ASD, 72 did not have global developmental delay (GDD) and were excluded from the study...

Impulsive Raman excitation in neat organic liquids far from resonance is followed using chirped broad-band supercontinuum probe pulses. Spectral modulations due to impulsively induced coherent vibrations vary in intensity 10-fold as a function of the probe's linear chirp. Simulations clarify why the vibrational signature is maximized for a group delay dispersion (GDD) in reduced units of νvib(-2) = 0.5 while a probe GDD of twice that quenches the same spectral modulations. Accordingly, recent claims that chirped white-light probe pulses provide equivalent information on material response to their compressed analogues must be taken with caution...

Purpose: To study the functional outcomes of filtration surgery by implanting improved glaucoma drainage devices (GDDs) comprising surface grooves and a composite coating of cyclosporine A (CsA) and PLGA in experimental rabbit eyes. Methods: Improved GDDs were designed and prepared by modifying normal GDD with surface grooves and a CsA-PLGA composite coating. Normal GDDs, grooved GDDs (G-GDDs), and G-GDDs with a CsA-PLGA composite coating (CsA@G-GDD) were implanted into 18 rabbit eyes (six eyes per group)...

Glaucoma is one of the leading causes of blindness in the world. Although there is no cure for glaucoma, pharmaceutical or surgical interventions are known to delay the progression of this debilitating disease. In recent years, implantation of glaucoma drainage devices (GDD) have increased due to their ability to manage IOP better than other therapeutic approaches. However, only 50% of the implanted devices remain functional after 5 years often due to biofouling. Here, we report our latest progress towards developing self-clearing GDDs using integrated magnetic microactuators...

PURPOSE: To evaluate efficacy of combined vitrectomy with posteriorly placed glaucoma drainage device (GDD) in lowering intraocular pressure (IOP) in children. METHODS: The medical records of children who underwent vitrectomy with posteriorly placed GDD were reviewed retrospectively. Patients with a minimum of 6 months' follow-up were included. The first eye operated on for each patient was analyzed. Success was defined as IOP of 5-20 mm Hg and no additional IOP-lowering surgery or visually devastating complications...

Global developmental delay (GDD) is a chronic neurological disturbance which includes defects in one or more developmental domains. The developmental domain can be motor, cognitive, daily activities, speech or language, and social or personal development. The etiology for GDD can be prenatal, perinatal, or postnatal. It can be diagnosed early in childhood as the delay or absence of one or more developmental milestones. Hence the role of pedodontist and pediatricians becomes more crucial in identifying this condition...

Gnathodiaphyseal dysplasia (GDD; MIM#166260) is an autosomal dominant syndrome with characteristic cemento-osseous lesions of jawbones, bone fragility, and diaphyseal sclerosis of tubular bones. To date, only five mutations in the proposed calcium-activated chloride channel ANO5/TMEM16E gene have been identified. In this study, we describe two families and two singular patients with three new mutations. One Caucasian family with seven affected members exhibited frequent bone fractures and florid osseous dysplasia (p...

A dispersive multilayer interference mirror with a group delay dispersion (GDD) of +1500  fs<sup>2</sup> for the spectral range of 9-11.5 μm is presented. It is designed to compensate the GDD of an ultrashort light pulse gained when transmitting 1 mm of a zinc selenide substrate. The coating process for the mirror manufacturing is described. The optical properties of the mirror are fully characterized by measuring the group delay, the GDD, the reflectance, and the transmittance.

AIM: To compare the intermediate-term efficacy of a large surface area Baerveldt 350 mm(2) glaucoma drainage device (GDD) with medium surface area implants (Baerveldt 250 mm(2) and Molteno 3, 230, or 245 mm(2)). DESIGN: This is a retrospective, nonrandomized comparative trial. MATERIALS AND METHODS: A total of 94 eyes of 94 patients of mixed glaucoma diagnoses without any prior glaucoma surgical procedures and who had undergone a glaucoma drainage implant surgery with either a large Baerveldt 350 mm(2) GDD or a medium-sized GDD (Baerveldt 250 mm(2) or Molteno 230 or 245 mm(2)) were reviewed for intraocular pressure (IOP), number of glaucoma medications, and visual acuity (VA) preoperatively, and at 1, 2, and 3 years postprocedure...

EDITORIAL
Cooper D Rodgers, Alissa M Meyer, Mark B Sherwood
There is ambiguity in the literature regarding whether a larger glaucoma drainage device (GDD) achieves a lower long-term intraocular pressure (IOP). There is some evidence on both sides, but overall there seems to be an optimal surface area of approximately 200-250 mm(2) beyond which there may be little advantage to increasing the plate size for most patients.

PURPOSE: To provide guidelines for safe implantation of glaucoma drainage devices (GDDs) in small and pediatric eyes to avoid contact between the optic nerve (ON) and the posterior edge of the GDD plate. METHODS: We developed a formula for calculating limbus-to-ON distance to estimate the available "real estate" for GDD placement in small eyes. The formula was validated using eyes of pediatric decedents undergoing clinical autopsy, with axial lengths (AL) of 15-24 mm...

Global developmental delay (GDD), often accompanied by intellectual disability, seizures and other features is a severe, clinically and genetically highly heterogeneous childhood-onset disorder. In cases where genetic causes have been identified, de novo mutations in neuronally expressed genes are a common scenario. These mutations can be best identified by exome sequencing of parent-offspring trios. De novo mutations in the guanine nucleotide-binding protein, beta 1 (GNB1) gene, encoding the Gβ1 subunit of heterotrimeric G proteins, have recently been identified as a novel genetic cause of GDD...
