We have previously shown that heart-shaped balloons have a different explosion mechanism than spherical balloons in which the former splits into two rubber parts still attached to the balloon base with a backward whiplash motion. This backward whiplash motion may cause significant blunt ocular trauma if the balloon is inflated by mouth. In this article, the energy of the blunt ocular trauma is estimated by the high speed camera photos analysis of the balloon burst. Furthermore, we describe the followup of eight patients with ocular trauma following inflation of heart-shaped balloons.

Approximately 3% of individuals in road traffic accidents suffer ocular injuries. We present a case of a man in his late 80s who presented with bilateral corneal decompensation following airbag deployment during a road traffic accident. Ocular examination revealed multilevel ocular injury with severe bilateral corneal oedema.

Late-life depression (LLD) is a psychiatric disorder in older adults, characterized by high prevalence and significant mortality rates. Thus, it is imperative to develop objective and cost-effective methods for detecting LLD. Individuals with depression often exhibit disrupted levels of arousal, and microsaccades, as a type of fixational eye movement that can be measured non-invasively, are known to be modulated by arousal.

Introduction: Rhabdomyosarcoma (RMS) originates from undifferentiated mesenchymal cells that give rise to striated muscles. The symptoms of para-meningeal RMS often resemble those of allergic rhinosinusitis, including nasal congestion, mucus discharge, headache, and occasional nosebleeds. We report a child with atypical clinical presentation of ocular hypertropia secondary to para-meningeal RMS.

Due to its rarity and complexity, standardized glaucoma surgical management is limited. To our knowledge, the application of glaucoma drainage devices in CEU is rarely documented.

Bacillary layer detachment (BALAD) refers to the distinctive splitting at the level of the photoreceptor inner segment myoid and accumulation of intraretinal fluid, as seen on optical coherence tomography (OCT). BALAD is an increasingly recognized OCT biomarker of numerous heterogeneous chorioretinal diseases, including posterior uveitis, age-related macular degeneration and macular neovascularization, neoplastic and paraneoplastic retinal disorders, rhegmatogenous retinal detachment, blunt ocular trauma, and miscellaneous conditions. The recognition of BALAD is clinically relevant because, based on the specific etiology, BALAD may require simple observation, ocular or systemic medical treatment, or even surgical intervention, with subsequent different prognosis.
