Effects on Posture of a Two-Diopter Horizontal Prism Base Out on the Non-Dominant Eye.

: Ocular proprioception is implicated in balance control and heterophoria is associated with abnormal posture, though previous research focused mainly on the role of vertical phoria and the use of vertical prisms. This study aims to evaluate whether ocular misalignment and prismatic correction of horizontal phoria affect posture. : Sixty-nine ( = 69) young healthy subjects were included and equally divided by horizontal distance phoria: orthophoria ( = 23), esophoria ( = 23) and exophoria ( = 23).

Comparing New Smartphone-Connected Handheld Ultrasound Device vs. Traditional Ultrasound in Vitreo-Retinal Disease Diagnosis.

(1) Background: Ocular emergencies account for 1.5-3% of emergency department (ED) visits and require urgent diagnosis to prevent serious complications. Ultrasonography is a crucial, non-invasive diagnostic tool for these conditions but traditionally lacks portability and integration with modern electronic smart devices.

Retinal Reactive Astrocytic Tumor and Astrocytic hamartomas in patient with Neurofibromatosis type 1: Case Report and Literature review.

Introduction: Neurofibromatosis type I, also known as Von Recklinghausen disease, is a common phakomatosis affecting 1 in 2500-3000 live births; it may be associated with several common ocular findings, including Lisch nodules, plexiform neurofibromas, optic pathway gliomas, retinal astrocytic hamartomas and choroidal nodules.

Case Description: This report illustrates clinical evidence of simultaneous presence of retinal reactive astrocytic tumor (RRAT) and two retinal astrocytic hamartomas (RAH) in a 15 y/o patient with NF1, referred to our attention because of an asymptomatic fundus mass in his right eye of recent onset.

Conclusion: This case, in addition to considering NF1 as one of the ocular conditions associated with secondary RRAT, underlines the importance of early referral and continuous ophthalmological follow-up in preventing possible complications that could cause significant visual impairment in patients with NF1.

Ocular Tics and Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections (PANDAS).

Little is known about ocular tics in Pediatric Autoimmune Neuropsychiatric Disorders associated with Streptococcal infections (PANDAS). In this retrospective study, we examined the clinical records of children with motor tics referred to the Ophthalmology Unit, Azienda Ospedaliero-Universitaria di Sassari, Italy, in 2010-2019. The presence of ocular tics was investigated.

Design: Prospective case series.

Epithelial cyst of the superior oblique muscle trochlea.

Most of the congenital orbital cysts are choristomas such as dermoid or epidermoid and only in a few cases they are epithelial. Clinically, they manifest as cystic movable formations mostly localized in the upper temporal quadrant of the orbit. We describe here the case of a 49-year-old man with an orbital cyst localized in the upper-nasal quadrant of the orbit and which was showing signs of a gradual enlargement and progression over the past weeks.

Orbital glomangioma.

Glomangioma is a vascular hamartomatous tumor originating from the glomus body, a specialized thermoregulatory organ localized in the dermis and precoccygeal soft tissue. Glomus tumors are characteristically found in the hands and are very rarely reported in the head region. Here we describe a 29-year-old woman presenting with acute proptosis and pain in the left eye.

Purpose: To determine the microbial contamination of the irrigating fluids at the time of phacoemulsification after the use of topical povidone-iodine and antibiotics prophylaxis.

Methods: A total of 119 patients undergoing cataract surgery were enrolled in this prospective study. All patients received 5 mg/mL levofloxacin starting from the day prior to surgery and topical and 5% povidone-iodine drops starting from 30 minutes before the surgery.

Retinal detachment and convexity intracranial meningioma: an uncommon association.

Case Report: A 70-years-old woman presented with a one week history of progressive loss of vision in the right eye (RE) diagnosed as retinal detachment from 7 to 1 o' clock with retinal break at the 10.30 o' clock associated. Gadolinium enhanced magnetic resonance imaging (MRI) scan of the brain and orbits with fat suppression showed a convexity meningioma.

Spindle cell lipoma of the orbit: a case report of an unusual orbital pathology.

Spindle cell lipoma is a rare and distinct variant of soft tissue tumour characterised by spindle cells in which the fat content may be scarce or absent. Most spindle cell lipomas arise as a subcutaneous mass of the neck, shoulders or back. Rarely, they can also be found in unusual sites, such as the oral cavity, larynx, bronchus, breast, and extremities.

Pseudophakic eye globe disruption.

Purpose: Scleral rupture due to bulb bursting can result from a heavy contusion. Owing to refined surgical techniques and the use of antibiotics and cortisone-based medication, more conservative concepts have followed. In major ruptures, the results were almost always very poor, with atrophy or subatrophy of the eyes.

Long-term effectiveness of lumboperitoneal flow-regulated shunt system for idiopathic intracranial hypertension.

Aim: The aim of the study was to assess the efficacy of lumboperitoneal flow-regulated shunt for the treatment of idiopathic intracranial hypertension (IIH).

Methods: This was a retrospective study carried out on four patients with IIH, treated from January to December 2007 with lumboperitoneal flow-regulated shunt (OSV II Smart Valve Systems; Integra NeuroSciences). The mean follow-up period was 13 months.

Lymphatic vessels in human eyelids: an immunohistological study in dermatochalasis and chalazion.

We investigated lymphatic morphology and expression of endothelin (ET-1) axis molecules in human eyelids affected by an inflammatory state (chalazion) and an age-related degenerative condition (dermatochalasis). Lymphatics were immunohistologically detected by D2-40/LYVE-1 staining. Absorbing lymphatic vessels were localized in papillary dermis and around skin appendages with distinctive morphology.

Ocular manifestations of chronic graft-versus-host disease in patients treated with extracorporeal photochemotherapy.

Purpose: Eye involvement has long been appreciated in patients with chronic graft versus host disease (cGVHD). In particular, ocular complications are frequent and can be potentially severe in patients with steroid-refractory cGVHD, and therefore necessitate close monitoring. This prospective study was designed to describe eye manifestations of cGVHD in a large series of patients monitoring them before and after 1 year of extracorporeal photochemotherapy (ECP).

Endothelin-1 and endothelin-converting enzyme-1 in human granulomatous pathology of eyelid: an immunohistochemical and in situ hybridization study in chalazia.

Endothelin-1 (ET-1), a potent vasoconstrictor peptide, is involved in several functions of eye pathophysiology, such as regulation of intraocular tension and retinal reactive vasoconstriction. As ET-1 pro-inflammatory and fibrosing activity is emerging in different fields of pathology, we investigated the expression of ET-1 and endothelin-converting enzyme-1 (ECE-1) in chalazia, granulomatous lesions of the eyelid. ET-1 and ECE-1 were analyzed by immunohistochemistry (IHC) in twenty surgically removed chalazia, with regard to expression in eyelid structures and inflammatory infiltrate.
