A 13-year-old, female, mixed, cocker spaniel was examined for a unilateral exophthalmia and protruding mass in episcleral region of the right eye. Mode B ocular ultrasonography revealed a mass extended intraocular from anterior chamber to posterior pole without evidence of extraocular extension. A presumptive diagnosis of melanocytic tumour was made. A complete blood count and chemistry and tho...
BACKGROUND A growing body of evidence suggests that effective blood pressure reduction may inhibit the progression of microvascular damage in patients with essential arterial hypertension. However, the potential influence of anti-hypertensive drugs on ocular circulation has not been studied sufficiently. PURPOSE The aim of our study was to evaluate the effects of anti-hypertensive therapy on ...
500 consecutive patients were evaluated for extracranial disease of the internal carotid arteries by an automated, air-filled, digital oculoplethysmographic system (OPG) of the Kartchner type (Zira) and by supraorbital (SO) and supratrochlear (ST) directional Doppler ultrasonography. Cerebral arteriograms were performed in 58 patients (110 vessels), and OPG timing criteria for detecting hemodyn...
BACKGROUND Ocular episcleritis and uveitis are well-recognised extra-intestinal manifestations of Crohn's disease. Orbital myositis is rare: to our knowledge it has been associated with Crohn's disease in thirteen cases. Posterior scleritis, orbital myositis and Crohn's disease have been reported as coexisting in only two cases. METHODS AND RESULTS We describe a third case, that of a 31-year ...
Enzymatically degradable semi-interpenetrating polymer networks (edsIPNs) were explored for their biocompatibility and ability to promote new scleral tissue growth, as a means of reinforcing the posterior wall of the eye. The edsIPNs comprised thermoresponsive poly(N-isopropylacrylamide-co-acrylic acid), customizable peptide crosslinkers cleavable by matrix metalloproteinases, and interpenetrat...
PURPOSE To report branch retinal artery occlusion (BRAO) in a patient with patent foramen ovale (PFO). CASE REPORT A 29-year-old female patient was referred for sudden onset superior visual field defect in her left eye. Ocular examination revealed visual acuity of 20/32 in the affected eye along with a positive relative afferent pupillary defect. A calcified white embolus was noted at the fir...
PURPOSE To report the relationship between different optical ocular components and the influence of axial length on emmetropization. METHODS 109 young university students, divided into five groups, were enrolled in this study: emmetropes, hyperopes, low myopes, moderate myopes and high myopes. Intraocular parameters and topographic corneal analyses were performed by ultrasonography and videok...
A 20-year-old white female, who is an avid tanning-bed user, was referred for the evaluation of a pigmented lesion in her left eye. She reported occasional lid swelling, pain, tearing and light sensitivity for two years, which she attributed to wearing contact lenses. The patient received a diagnosis of ocular melanosis 6 months prior to her current presentation. On examination, the best-correc...
We present the case of a 12-year-old boy with Sturge-Weber syndrome and ocular melanocytosis who presented with bilateral naevus flammeus of the face and hyperpigmentation of the right iris associated with ipsilateral iris mammillations. The patient had glaucoma and a diffuse choroidal haemangioma of the right eye. Optical coherence tomography of the anterior segment confirmed iris hyper-pigmen...
To cite: Pujari A, Swamy DR, Chawla R, et al. BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/ bcr-2017-219287 DESCRIPTION The ocular ultrasonography has evolved over years; the combined mode using A-scan and B-scan is very useful in the diagnosis of posterior segment pathology. Brightness mode helps in better evaluation of the mass lesion regarding their size, shape,...
