Mittendorf's dot and posterior embryotoxon are both congenital abnormalities affecting the anterior segment, which arise during early foetal life. We report of a 36-year-old female patient newly diagnosed as having a potentially occludable anterior chamber angle in the right eye and coexisting Mittendorf's dot and posterior embryotoxon. The patient elected to undergo prophylactic laser iridotomy in the affected eye. These findings may serve as additional factors to consider in the management of patients with narrow anterior chamber angles.
An 8-year and 2-month-old 37.2 kg crossbreed dog was presented with a persistent cough. Thoracic computed tomography was performed and identified a large lobar mass sitting within the left main stem bronchus. The mass was deemed operable, but considering the unique technical challenges associated with the surgery (need for specific ventilation strategies and risk of major haemorrhage) a guarded prognosis was given. A total left-sided pneumonectomy via a lateral thoracotomy was performed. One-lung ventilation was required in order to allow surgical access. During the surgery, the dog suddenly developed atrial fibrillation, which converted back to a normal sinus rhythm (SR) during the recovery period. The dog recovered uneventfully following the return to SR and was discharged 72 hours after the surgery. Histopathological results of the lung mass concluded to a primary pulmonary chondrosarcoma.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
