Eye movements in children with strabismus +/- amblyopia

The aim of this study was to detect eye movement recording abnormalities using different paradigms in children with strabismus in the absence or presence of amblyopia and compare these findings with age-matched children without strabismus. One hundred children were recruited...

Undetected retinoblastoma management following vitrectomy

This retrospective study from a single-centre referral university hospital in Germany analysed data collected between 1991-2019 to comment on management and complications of undetected retinoblastoma eyes following vitrectomy. The 10 patients included had a mean age of 36.1 months (range...

Evaluation of ectopia lentis et pupillae (ELP)

The ADAMTSL4 gene encodes proteins for cellular adhesion, angiogenesis, nervous system development and anterior / posterior segment structures. This case report describes a four-year-old female with diagnosis at referral of ELP. A three-generation pedigree was obtained and was negative for...

Mimicked tumour seeding due to asteroid hyalosis

A case report is presented of a patient with treated retinoblastoma (RB) who later developed asteroid hyalosis which mimicked tumour seeding. The case was a 37-year-old male with presenting symptoms of vitreous floaters. A unilateral RB was diagnosed at the...

Management of large hypertropia due to lost inferior rectus

This case report outlines the management strategy for a 37-year-old male who suffered a penetrating left orbital injury with rupture of the inferior rectus muscle, optic nerve avulsion and vertical deviation of about 90PD. On orbit exploration, the inferior rectus...

Mediation of vertical vergence

The authors hypothesised that if vertical vergence were mediated by vertical rectus muscles, then the eye that moves during a vertical fusion task would produce larger vertical vergence when abducted versus adducted. Similarly, if mediated by the oblique muscles then...

Lang Stereopad comparisons

The aim of this study was to compare the effectiveness of the Lang Stereopad in detecting and measuring stereopsis in a population with normal visual parameters. The Lang Stereopad was compared directly to the Frisby, TNO and Lang II stereotests...

Medical treatment of orbital lymphatic malformations

This is a literature review of the use of Sirolimus, to treat orbital lymphatic malformations. Sirolimus is an immunosuppressant used in renal transplants, and acts by inhibiting mammalian target of rapamycin (mTOR), which in turn inhibits activation of T and...

CD73 in aggressive basal cell carcinoma

This is a retrospective review looking at levels of CD73 in aggressive basal cell carcinomas (BCCs) that invade the orbit. Eleven patients who underwent orbital exenteration for invasion by BCCs were compared with 10 matched controls who had simple nodular...

Duane’s retraction syndrome (DRS)
