PURPOSE: Diagnosing thyroid eye disease-compressive optic neuropathy (TED-CON) is challenging, particularly in cases lacking a relative afferent pupillary defect. Large case series of TED-CON patients and accessible diagnostic tools are lacking in the current literature. This study aims to create a mathematical formula that accurately predicts the presence or absence of CON based on the most salient clinical measures of optic neuropathy. METHODS: A retrospective case series compares 108 patients (216 orbits) with either unilateral or bilateral TED-CON and 41 age-matched patients (82 orbits) with noncompressive TED...

Introduction: Although the current Zika virus (ZIKV) epidemic is a major public health concern, most reports have focused on congenital ZIKV syndrome, its most devastating manifestation. Severe ocular complications associated with ZIKV infections and possible pathogenetic factors are rarely described. Here, we describe three Venezuelan patients who developed severe ocular manifestations following ZIKV infections. We also analyse their serological response to ZIKV and dengue virus (DENV)...

Paraneoplastic syndromes involving the visual system are a heterogeneous group of disorders occurring in the setting of systemic malignancy. Although these syndromes are rare, the clinical manifestations can herald an unsuspected, underlying malignancy. The associated antibodies and histopathology of each syndrome are presented to help in the understanding of these autoimmune phenomena. Outlined in this review article are diagnostic features useful in differentiating cancer-associated retinopathy, melanoma-associated retinopathy, paraneoplastic polymorphous vitelliform maculopathy, bilateral diffuse uveal melanocytic proliferation and paraneoplastic neurologic syndromes such as optic neuropathy, opsoclonus-myoclonus, Lambert-Eaton myasthenia and paraneoplastic cerebellar degeneration...

PURPOSE: Despite the paucity of supporting data, it has generally been held that proptosis in thyroid eye disease (TED) may provide relative protection from compressive optic neuropathy (CON) by producing spontaneous decompression. The objective of this study was to investigate this phenomenon in patients with bilateral TED-CON. METHODS: We retrospectively reviewed the charts of 67 patients (134 orbits) with bilateral TED-CON at Columbia-Presbyterian Medical Center...

Leber's hereditary optic neuropathy is the most common mitochondrial condition and is characterized by bilateral, painless, subacute visual loss that develops during young adult life. LHON is a rare condition and this lack of knowledge can make doctors suspect and treat for other causes of vision loss. Typically, a series of tests are performed to confirm LHON diagnosis or exclude any other conditions. We presented the case of two brothers, HB, of 40 years old and HF, of 38 years old, who presented with a decrease in visual acuity in both eyes...

Paraneoplastic syndromes involving the visual system are a heterogeneous group of disorders occurring in the setting of systemic malignancy. They are unrelated to local tumor invasion or metastasis and unexplained by nutritional, metabolic, infectious or iatrogenic causes. The presence of antibodies may aid in the diagnosis of a paraneoplastic syndrome, although this is not an absolute requirement. Chorioretinal involvement is seen in CAR (cancer-associated retinopathy) syndrome, MAR (melanoma-associated retinopathy) syndrome, paraneoplastic vitelliform maculopathy, and bilateral diffuse uveal melanocytic proliferation...

Leber hereditary optic neuropathy is characterized by bilateral, painless loss of vision in children and young adults (generally up to 25 years old). Since its first description in 1871, the understanding of its etiology and pathogenesis has improved considerably. The article considers Leber neuropathy from the points of view of ophthalmology, neurology and molecular genetics, and presents data on experimental treatment methods, one of which is undergoing clinical trial.

BACKGROUND: POEMS syndrome is a plasma cell disorder, which clinically manifests from paraneoplastic syndrome: polyneuropathy, organomegaly, endocrinopathy, monoclonal plasma cell disorder, and skin changes. The most common ocular manifestation is optic disc swelling, whereas other ocular manifestations; cystoid macular edema, serous macular detachment, venous sinus thrombosis, infiltrative orbitopathy, uveitis, neovascularization of the disc, peripapillary choroidal neovascularization and optic disc drusen, had also been reported...

INTRODUCTION: Potential factors influencing stereopsis were investigated in patients with both refractive accommodative esotropia (RAE) and amblyopia. Pigment dispersion syndrome (PDS) is a condition where anomalous iridozonular contact leads to pigment dispersion throughout the anterior segment and the released pigment is abnormally deposited on various ocular structures. CLINICAL PRESENTATION: The clinical presentation of PDS is defined by the presence of pigmented cells on the corneal endothelium, an increase of pigmentation of the trabecular meshwork, and mid-periphery transillumination defects of the iris...

Trauma surgeons are currently encountering unusual adverse events after traumatic injuries. Ischemic optic neuropathy is a rare complication that may occur in trauma and burn patients that present in extremis and require massive resuscitation. A 29-year-old male patient sustains a penetrating injury to the heart that required primary repair. He remained hemodynamically stable and required a limited amount of resuscitative fluids and products. Postoperatively, the patient develops acute painless bilateral loss of vision...

An 81-year-old man with bilateral progressively blurry vision and optic disc swelling was referred for evaluation. Examination and ancillary testing confirmed a diagnosis of bilateral vitreopapillary traction (VPT) accompanied by unilateral tractional retinoschisis in the right eye. Pars plana vitrectomy was performed to release the traction in both eyes. Visual acuity improved in the right eye and stabilized in the left eye. Retinoschisis in the right eye resolved. The visual field improved in both eyes, although the left eye demonstrated a persistent hemifield defect likely attributable to a prior optic neuropathy...

BACKGROUND: Postoperative posterior ischemic optic neuropathy (PION) is a rare cause of postoperative vision loss, most often seen when surgical patients are placed in the prone position for a prolonged period of time. We report a case of bilateral PION after far-lateral craniectomy in the lateral position. CASE DESCRIPTION: A 36-year-old man presented with a history of right extremity numbness, weakness, and muscle atrophy, and a craniocervical meningioma was diagnosed...

PURPOSE: Although most totally visually blind individuals exhibit nonentrained circadian rhythms due to an inability of light to entrain the circadian pacemaker, a small proportion retain photic circadian entrainment, melatonin suppression, and other nonimage-forming responses to light. It is thought that these responses to light persist because of the survival of melanospin-containing intrinsically photosensitive retinal ganglion cells (ipRGCs), which project primarily to the circadian pacemaker and are functionally distinct from the rod and cone photoreceptors that mediate vision...

We evaluated thirteen eyes of twelve patients diagnosed clinically and serologically with Toxocara optic neuropathy. Eleven patients had unilateral involvement and one patient had bilateral optic neuropathy. Eight patients (66.7%) had a possible infection source to Toxocara. Six patients (50%) had painless acute optic neuropathy. Ten eyes had asymmetric, sectorial optic disc edema with peripapillary infiltration and three eyes had diffuse optic disc edema. Eosinophilia was noted in five patients (41.7%) and optic nerve enhancement was observed in eight of eleven eyes (72...

BACKGROUND: The Pulfrich phenomenon (PF) is the illusory perception that an object moving linearly along a 2-D plane appears to instead follow an elliptical 3-D trajectory, a consequence of inter-eye asymmetry in the timing of visual object identification in the visual cortex; with optic neuritis as a common etiology. OBJECTIVE: We have designed an objective method to identify the presence and magnitude of the PF, in conjunction with a cooresponding strategy by which to abolish the effect; with monocular application of neutral density filters to the less affected fellow eye, in patients with MS and a history of optic neuropathy (e...

This report describes a 66-year-old Caucasian male who acutely developed severe, bilateral impairment of visual acuity at 24 years of age. Leber's hereditary optic neuropathy (LHON) was suspected but the diagnosis was not genetically confirmed until the age of 49 years when the primary LHON mutation m.3460G>A was detected. Since onset, visual acuity had slightly improved. The family history was positive for LHON (brother, two sisters of mother, female cousin) and genetically confirmed in his brother and one aunt...

BACKGROUND/AIMS: We performed a retrospective analysis to examine clinical results, establish a dose-effect coefficient and analyze the long-term efficacy of tendon elongation with bovine pericardium (Tutopatch®) for surgical correction of severe esotropia, occurring after three-wall orbital decompression for dysthyroid optic neuropathy in patients with Graves' orbitopathy (GO). METHODS: Tendon elongation of the medial rectus muscle (MR) was performed in our institution using an interponate of bovine pericardium in 60 patients (27 underwent unilateral and 33 bilateral surgery)...

The purpose is to evaluate the utility of optical coherence tomography (OCT) angiography in the evaluation of Graves' orbitopathy (GO) and response to orbital decompression in patients with and without dysthyroid optic neuropathy (DON). This was a single-center, prospective case series in a cohort of 12 patients (24 orbits) with GO and ±DON, (6 orbits) who underwent bilateral orbital decompression. All patients underwent pre- and postoperative OCT angiography of the peripapillary area. Vessel density indices were calculated in a 4...
