Multi-gene panel testing is used increasingly in ophthalmology practice as an efficient and cost-effective method for diagnosing inherited eye conditions. Panel testing is a powerful diagnostic tool, and it has the potential to reveal syndromic information in patients with seemingly isolated eye findings. This case series highlights our experience with 4 children in 3 families who were referred for evaluation of an isolated retinal degeneration and diagnosed with neuronal ceroid lipofuscinosis on panel testing...

Normal vision requires coordination of precisely controlled and coordinated eye movements and normal function of a large cortical and subcortical sensory network. Given the required precision of the system and wide anatomic distribution of the motor and sensory visual systems, vision can be disrupted by a variety of central and peripheral nervous system disorders. While many of these may be relatively benign or have no proven therapy, several may be isolated presentations or harbingers of more serious neurologic conditions...

PURPOSE: Glaucoma is the leading cause of vision loss in eyes with Boston Keratoprosthesis (KPro). Glaucoma drainage devices (GDDs) have been shown to be effective in controlling glaucoma with KPro. Cicatricial conjunctival disease with forniceal shortening is a major challenge and limitation to the use of GDD. In our series, we report the success of fornix reconstruction in cicatricial ocular surface disease as a staged procedure prior to a combined KPro/GDD surgery. METHODS: Retrospective case series involving 4 eyes with surface cicatricization...

Mutations in RAB18, a member of small G protein, cause Warburg micro syndrome (WARBM), whose clinical features include vision impairment, postnatal microcephaly, and lower limb spasticity. Previously, our Rab18-/- mice exhibited hind limb weakness and spasticity as well as signs of axonal degeneration in the spinal cord and lumbar spinal nerves. However, the cellular and molecular function of RAB18 and its roles in the pathogenesis of WARBM are still not fully understood. Using immunofluorescence staining and expression of Rab18 and organelle markers, we find that Rab18 associates with lysosomes and actively traffics along neurites in cultured neurons...

Background Monocular vision loss, attributed to either central retinal artery occlusion ( CRAO ), branch retinal artery occlusion ( BRAO ), or ocular ischemic syndrome ( OIS ), is thought to be associated with an increased prevalence of cerebral infarcts. However, there is a paucity of data substantiating this. We aimed to investigate this relationship in a Canadian center and further understand the importance of associated internal carotid artery stenosis in potential clinical decision making. Methods and Results We performed a retrospective cohort study at a comprehensive stroke center of patients presenting initially with CRAO , BRAO , or OIS to a centralized ophthalmology center over a 5-year period...

Brown's syndrome is related to an abnormality of the superior oblique muscle: it is manifested by an oculomotor disorder with active and passive limitation of elevation in adduction, the field of action of the inferior oblique muscle. The origin is congenital or acquired secondary to multiple causes - inflammatory-infectious, traumatic or iatrogenic. The clinical and paraclinical signs are suggestive. Cerebral and orbital imaging including CT and magnetic resonance imaging (MRI) is essential for the diagnosis and management of congenital or acquired Brown's syndrome...

A 16-year-old boy with a history of relapsed acute myeloid leukemia and a right lower lobe lung abscess confirmed to be Aspergillus presented for a baseline eye examination prior to consideration of bone marrow transplantation. He noted double vision in up-and-left gaze, and his examination was consistent with an acquired right-sided Brown syndrome. Magnetic resonance imaging revealed a 4 mm rim-enhancing inflammatory focus in the right superior oblique muscle. His Brown syndrome resolved after treatment with systemic antimicrobials...

Tubulointerstitial nephritis and uveitis (TINU) syndrome is a rare disease characterised by the association of acutetubulointerstitial nephritis and uveitis. It affects mainly children and young women. Drugs and infections may be precipitating factors. It is a diagnosis of exclusion. The mainstays of treatment are topical and systemic corticosteroids. Prognosis is usually favourable. We report a case of TINU which occurred in our unit. A 37-year-old woman presented with an influenza-like illness, bilateral ocular pain and blurred vision...

Radiologists typically spend long hours staring at the computer monitor. This unavoidable nature of our work can lead to detrimental effects on the eyes. Moreover, there is little awareness among radiologists with regards to such potential harm. Ocular hazards, such as computer vision syndrome, are increasingly becoming more relevant to the radiology community. In this article, we discuss the ocular occupational hazards faced by radiologists and suggestions that may help in minimizing such hazards.

PURPOSE: Sjögren's syndrome (SS) is a common autoimmune disease affecting about four million Americans. Although approximately 1 in 10 patients with clinically-significant aqueous deficient dry eye has underlying SS, widespread underappreciation of SS leads to significant underdiagnosis, delays in diagnosis, and consequent morbidity and mortality. The purpose of this article is to illustrate that in addition to dry eye, SS can cause serious, vision-threatening extraglandular ocular manifestations...

BACKGROUND: Ocular compartment syndrome (OCS) is a serious ophthalmological emergency that should be diagnosed and treated immediately to prevent permanent loss of vision. It is usually caused by a retro-orbital bleed that will subsequently increase intra-orbital pressure and threaten the patient's vision. Lateral canthotomy and cantholysis is a minor bedside procedure using simple equipment that is readily available in emergency departments, and the aim of such a procedure is to free the eye globe from its lateral attachment to the bony orbital wall and allow more eye protrusion and hence reduce intra-orbital pressure and save the patient's sight...

History A 1-year-old boy was referred for cochlear implant assessment after he received a diagnosis of bilateral profound sensorineural hearing loss at neonatal hearing screening shortly after birth. The child was born at term via uneventful delivery, and there was no history of familial hearing loss or maternal illness. Tympanic membranes were normal, and hearing loss was confirmed with auditory brainstem testing, which showed no response from either ear. Hearing aids were provided from 3 months of age, but no behavioral responses were noted when these were worn...

Faden operation was first described in 1912. It weakens the muscle in its field of action without much slackening and alteration in the primary position. When combined with recession the weakening effect is more. It is a useful surgery in esotropia with high accommodative convergence, nystagmus blockage syndrome, dissociated vertical deviation, Duane's retraction syndrome with up or downshoots, and in sixth nerve paresis, where it is performed on the contralateral normal yoke muscle to increase the field of binocular vision...

Peripheral nerves, which consist of an axon and a unique glial cell called a Schwann cell, transduce signals from the brain and spinal cord to target organs. Peripheral nerve degeneration leads to distal motor or sensory disorders such as diabetic neuropathy, Charcot-Marie-Tooth disease, and Gullain-Barré syndrome, with symptoms such as dysesthesia, speech impairment, vision change, erectile dysfunction, and urinary incontinence. Schwann cells play an important role in peripheral nerve degeneration. Therefore, revealing the characteristics of Schwann cells will be essential in understanding peripheral neurodegeneration-related diseases for which there is currently no effective treatment...

Purpose: Mutations in the megalin-encoding gene, LRP2, cause high myopia as seen in patients suffering from Donnai-Barrow/facio-oculo-acoustico-renal syndrome. Megalin is present in both the nonpigmented epithelium of the ciliary body and in the RPE. In this study, we set out to establish an animal model to study the mechanisms underlying the ocular phenotype and to establish if high myopia/megaophthalmos is induced by postnatal megalin-deficiency in the RPE. Methods: Postnatal RPE-specific deletion of megalin was generated by crossing mice bearing a homozygous loxP-flanked Lrp2 allele with transgenic mice expressing the Cre recombinase driven by the BEST1 promotor...
