Article Synopsis
  • - Osteogenesis Imperfecta (OI), or "brittle bone disease," is a rare genetic disorder that causes fragile bones and potential deformities due to defects in collagen type I, requiring comprehensive care throughout a patient's life stages.
  • - Treatment primarily focuses on supportive measures, including medications like bisphosphonates and various orthopedic surgeries, which have shown positive results, especially in children, but there is a notable lack of guidelines for adults transitioning from pediatric care.
  • - A systematic review of existing literature emphasizes the need for a multifaceted approach by various medical specialists to enhance the transition from pediatric to adult care for OI patients, stressing the importance of education, personalized plans, and ongoing follow-up.

Article Synopsis
  • Progressive isolated optic nerve glioma (ONG) in children is a rare condition with no standard treatment consensus, and a study was conducted to compare the effectiveness of different treatment methods.
  • The study involved 21 ONGs where systemic anticancer therapy (SAT) led to visual improvements in a significant number of cases, while surgery often resulted in worsening vision, and radiotherapy had mixed effects, including a potential increase in tumor volume shortly after treatment.
  • The findings suggest that SAT is the preferred treatment for preserving vision, while surgery may help alleviate other symptoms in blind patients, but radiotherapy poses risks and needs careful evaluation before use.

Article Synopsis
  • - The study analyzed 156 adults with Langerhans cell histiocytosis to see if BRAF mutation status affected disease severity or survival rates, finding no significant correlation.
  • - It was noted that BRAFV600E mutations were linked to a higher occurrence of second cancers, particularly hematological types, in patients.
  • - These second malignancies may share a common origin with the original condition, suggesting potential connections between them.

Ophthalmoparesis and ptosis can be caused by a wide range of rare or more prevalent diseases, several of which can be successfully treated. In this review, we provide clues to aid in the diagnosis of these diseases, based on the clinical symptoms, the involvement pattern and imaging features of extra-ocular muscles (EOM). Dysfunction of EOM including the levator palpebrae can be due to muscle weakness, anatomical restrictions or pathology affecting the innervation.

Article Synopsis
  • The study investigates the occurrence of A pattern strabismus in patients with Graves' orbitopathy who undergo surgery on the inferior rectus muscles, and identifies potential predictive factors.
  • 59 out of 590 patients developed this strabismus type post-surgery, with notable differences in muscle recession and ocular movement effects compared to a control group.
  • The findings suggest a significant link between increased muscle thickness in affected patients and the development of the A pattern, highlighting that nearly half needed additional surgery for proper vision alignment.

Goal of the study was to evaluate bony orbit remodeling and extraocular muscle (EOM) volume in thyroid eye disease (TED) and their role as predicting factors for development of dysthyroid optic neuropathy (DON). Orbital computed tomography of 92 patients with TED with (76 orbits) or without DON (98 orbits) were retrospectively evaluated. Orbits (n = 40) of subjects without TED served as controls.

Three-dimensional (3D) printing of ocular prosthesis has been scarcely described in medical literature. Although ocular prostheses have been 3D printed successfully, iris colors are often manually added to the final product afterward. The objective was to produce a 3D-printed ocular prosthesis with textured iris and sclera in one single print job.

Pediatric Graves' orbitopathy: a multicentre study.

Acta Ophthalmol

September 2022

Department of Ophthalmology, Orbital Center, Amsterdam University Medical Centers, University of Amsterdam, Amsterdam, The Netherlands.

Purpose: Graves' orbitopathy (GO) is a rare condition in children often considered to be a less severe condition than at an older age. The aim of our study was to analyse if there are any factors that distinguish paediatric from adult GO in order to provide guidelines for assessing and managing paediatric GO.

Methods: Study design is a multicentre retrospective observational case series; 115 paediatric patients diagnosed with GO who visited our university medical centres in the Netherlands and Iran between 2003 and 2019 were submitted for complete ophthalmological examinations, serological testing and/or orbital imaging.

Purpose: Retinal alterations in inherited metabolic diseases associated with neurodegeneration are poorly studied. The objective was to study retinal thickness, specifically the components of the ganglion cell complex (GCC)-nerve fiber layer (NFL), ganglion cell layer (GCL), and inner plexiform layer (IPL)-using spectral-domain optical coherence tomography (SD-OCT) in two different diseases with potential dopaminergic depletion, phenylketonuria (PKU) and Gaucher disease type 3 (GD3).

Methods: Retinal layers in 19 patients with PKU, 15 patients with GD3, and 93 healthy individuals were measured using peripapillary ring scan and macular SD-OCT.

Recurrent contracted sockets treated with personalized, three-dimensionally printed conformers and buccal grafts.

Eur J Ophthalmol

January 2022

Amsterdam UMC, Department of Ophthalmology, Amsterdam Orbital Center, University of Amsterdam, Meibergdreef 9, Amsterdam, the Netherlands.

Purpose: Recurrent contracted sockets are complex situations where previous surgeries have failed, disabling the wear of an ocular prosthesis. A combined method of surgery and long-term fixation using custom-made, three-dimensional (3D) printed conformers is evaluated.

Methods: Retrospective case series of nine patients with recurrent excessive socket contraction and inability to wear a prosthesis, caused by chemical burns ( = 3), fireworks ( = 3), trauma ( = 2) and enucleation and radiotherapy at childhood due to optic nerve glioma ( = 1) with three average previous socket surgeries (range 2-6).
