PURPOSE: To evaluate the effects of carotid artery angioplasty and stenting (CAAS) on patients who were diagnosed with ocular ischemic syndrome (OIS). METHODS: Sixty-four eyes of 64 OIS patients with ipsilateral internal carotid artery stenosis ≥70% were included in the study. The study eyes were divided into two groups according to the presence of iris neovascularization: NVI-absent group and NVI-present group, with 32 eyes, respectively. All patients received ocular treatment modality according to the presence of non-perfusion area (pan-retinal photocoagulation) and intraocular pressure (medical treatment included timolol maleate eye drops combined with brinzolamide eye drop; trabeculectomy and cyclophotocoagulation)...

Posterior keratoconus (PKC) is a rare, typically non-inflammatory condition that is characterised by an abnormal posterior corneal curvature, which may be accompanied by overlying stromal opacification. It is usually congenital and can be associated with other ocular and systemic abnormalities. PKC remains a clinical diagnosis, although imaging techniques including ultrasound biomicroscopy and anterior segment optical coherence tomography may be useful tools for confirmation and classification. Genetic studies should be considered, although no specific genetic defects have been identified thus far...

INTRODUCTION: The prevalence and etiology of neovascular glaucoma (NVG) as a complication of central retinal artery occlusion (CRAO) is a debated issue. According to some authors, NVG associated with CRAO always involves underlying chronic ocular ischemic syndrome (COIS) as a primum movens for CRAO. However, we describe 5 cases of NVG following CRAO with no underlying COIS, confirmed by carotid Doppler studies and ultrasound color Doppler imaging (USCDI) of the ophthalmic artery (OA)...

Melanomas are aggressive cancers that present as cutaneous, mucosal and ocular lesions with the ability to metastasise widely. There are, however, occasions where lesions are found in distant sites such as lymph nodes, viscera and subcutaneous tissues without clinically apparent skin involvement. This is known as metastatic melanoma of unknown primary (MUP). Its presentation in skeletal muscle is rare, and the available literature is sparse. This article presents an 85-year-old woman with a MUP presenting in the right temporalis muscle, which was diagnosed with the aid of the ultrasound-guided core biopsy...

BACKGROUND: Severe vision-impairing ocular inflammation is rarely reported following extensive laser. Previous cases have involved retinal photocoagulation for diabetic retinopathy resolving over days. This report documents a rare instance of this where encircling retinopexy/cerclage was done as fellow eye retinal detachment prophylaxis in a patient with no overt comorbidities. RESULTS: A panuveitis-like reaction with severe, near-total visual impairment was documented 1 day following single-sitting encircling laser retinopexy/cerclage done as fellow eye prophylaxis for a 21-year-old male presenting with total retinal detachment in the other eye...

Jing Lu, Yan Luo, Lin Lu
BACKGROUND: Vitreous cysts are rare clinical findings and seldom cause visual disturbance. They are generally classified as congenital or acquired and are considered idiopathic when the etiology can not be determined. A previous electron microscopic observation on an idiopathic pigmented vitreous cyst has confirmed its pigment epithelial origin. However, the specific kind of pigment epithelium involved remains unclear. CASE PRESENTATION: A 39-year-old female presented with a round-shaped floater causing frequent visual disturbance in the left eye...

Point-of-care ocular ultrasound can provide the clinician with more information about potential intraorbital and extraocular pathology, especially in cases when direct visualization of the eye is limited. This case report describes the findings in a pediatric patient who presented with a 1-month history of eye injection and worsening blurry vision. After point-of-care ultrasound demonstrated abnormal debris in the posterior vitreous cavity, subsequent evaluation revealed a diagnosis of pars planitis.

Ultrasound biomicroscopy (UBM) is a valuable diagnostic modality for imaging anterior ocular structures. Its utility has been well studied in anterior segment, lenticular, and pars plicata pathologies. However, imaging of the pars plana has been seldom described. We present the case of a 66-year-old woman referred for vitreous hemorrhage after expulsive cannula dislodgement into the posterior segment during wound hydration at the end of cataract surgery. B-scan ultrasonography initially detected a very anterior abnormality, but the resolution was insufficient for accurate diagnosis...

A case of exophthalmos due to zygomatic mucocele in a puppy with ipsilateral segmental maxillary atrophy is reported. A 7-month-old, mixed breed, male dog suffered the sudden-onset of unilateral painful exophthalmos and a gradual swelling of the right temporal region. A compressing, right retrobulbar mass was observed by ultrasound. Computed tomography revealed a large multiloculated cyst-like lesion of the right zygomatic gland projecting into the orbital space, thus displacing the eyeball. The ipsilateral molar part of the maxillary bone was underdeveloped, besides showing crowded, abnormal, multiple, unerupted maxillary molar teeth in the caudal maxillary region...
