Purpose: The purpose of this study was to evaluate the efficacy of new viscous cysteamine hydrochloride (CH) eye drops (vCH 0.55%) compared with standard CH 0.10% drops treatment. Methods: This was an open-label, phase III, randomized, two-arm multicenter trial conducted at two centers in France. Cystinosis patients ≥2 years old were randomized 1:1 to receive eye drops, four times per day for 90 days in both eyes. We compared the superiority in reducing corneal cystine crystal density as assessed by in vivo confocal microscopy (IVCM)...

Importance: The ocular manifestations and sequelae of Zika virus infection are not well known. Recently, the World Health Organization changed the declaration of Zika as a public health emergency and designated the viral outbreak and related microcephaly clusters as a long-term program of work. This change indicates the urgent need to evaluate and document ophthalmic manifestations in patients for timely management of this disease. In addition, confirmation whether the public health problem in Brazil extends to other regions in South America is needed...

Objective: To investigate the clinical features of vestibular migraine with MRI changes. Methods: The clinical data of 150 patients with vestibular migraine completing MRI examination in navy general hospital from August 2008 to August 2016 were retrospectively analyzed.Clinical features of 94 (62.7%) vestibular migraine patients with MRI changes were collected and analyzed according to the medical history, clinical symptoms and signs, as well as the result of auxiliary examinations. Results: The manifestations of MRI in vestibular migraine patients were mainly multiple punctate equal T(1) and long T(2) signals or high signals on FLAIR (fluid attenuated inversion recovery) in subcortical white matter...

A 19-year-old previously healthy man presented, minimally responsive, in respiratory distress to an ED after a 2-week history of headache, photophobia, and neck stiffness. Associated symptoms included low-grade fevers, malaise, and dark urine. He had no recent travel, ill contacts, consumption of undercooked meat, new sexual contacts, or illicit drug use. The patient resided in a campus dormitory and did not consume alcohol or tobacco.

Background Autonomic dysfunction and light sensitivity are core features of the migraine attack. Growing evidence also suggests changes in these parameters between attacks. Though sensory and autonomic responses likely interact, they have not been studied together across the spectrum of disease in migraine. Methods We performed digital infrared pupillometry while collecting interictal photophobia thresholds (PPT) in 36 migraineurs (14 episodic; 12 chronic; 10 probable) and 24 age and sex-matched non-headache controls...

OBJECTIVE: To determine whether baseline nausea or prior triptan treatment for migraine impact the effectiveness of diclofenac potassium for oral solution in treating acute migraine. BACKGROUND: A great deal of variability exists in patients' response to migraine medications. Migraine-associated nausea is common and debilitating and can reduce the effectiveness of oral medications. It may cause patients to delay taking oral medications, which is known to diminish therapeutic outcomes, or to avoid taking them altogether...

Seung Pil Bang, Jong Hwa Jun
BACKGROUND: A large iris defect or extensive iridodialysis can be an intractable cause of visual disturbance, photophobia, glare, monocular diplopia, or cosmetic deformity. The implantation of an artificial iris substitute could be an effective option, but this can cause a reduction in endothelial cell density. We succeeded in the anatomical restoration of iris tissue that was totally dialyzed out of the eye, and was preserved in cold balanced salt solution for 8 h. Engrafted iris tissue was maintained within the aqueous humor...

REVIEW
Andreina Tarff, Ashley Behrens
"Red eye" is used as a general term to describe irritated or bloodshot eyes. It is a recognizable sign of an acute/chronic, localized/systemic underlying inflammatory condition. Conjunctival injection is most commonly caused by dryness, allergy, visual fatigue, contact lens overwear, and local infections. In some instances, red eye can represent a true ocular emergency that should be treated by an ophthalmologist. A comprehensive assessment of red eye conditions is required to preserve the patients visual function...

PURPOSE: Photophobia is a debilitating clinical condition that disrupts the ability to use vision for everyday tasks in bright lighting conditions. The goal of the study is to develop a methodology to study the neural basis of photophobia and the contribution of the melanopic pathway to its etiology with differential chromatic responses by means of standard electroencephalographic recording equipment. METHODS: We introduce and validate the approach of recording wavelength-specific electroretinographic (ERG) responses from the face electrodes of the high-density whole-head electroencephalography recording system under light-adapted conditions...

Features of Costello Syndrome, a systemic disorder caused by germline mutations in the proto-oncogene HRAS from the RAS/MAPK pathway, include failure-to-thrive, short stature, coarse facial features, cardiac defects including hypertrophic cardiomyopathy, intellectual disability, and predisposition to neoplasia. Two unrelated boys with Costello syndrome and an HRAS mutation (p.Gly13Cys) are presented with their ophthalmologic findings. Both had early symptoms of nystagmus, photophobia, and vision abnormalities...

BACKGROUND AND OBJECTIVES: Ocular/periocular involvement in pemphigus vulgaris (OPV) has rarely been reported. The objective of the present study was to investigate the pattern of OPV and define the prognostic value of its manifestation. PATIENTS AND METHODS: From 1985 to 2014, a total of 167 patients with pemphigus vulgaris (PV) were treated at four tertiary Spanish hospitals. In this retrospective study, we included all patients with OPV. Clinical data and information on associated symptoms were obtained from patients' medical records...

IFAP syndrome is a rare autosomal recessive X-linked disease characterized by the triad of alopecia universalis, severe photophobia, and follicular ichthyosis. It is caused by loss of function of the gene MBTPS2. Its severity varies and there are only a few reports in the literature. We present a patient with characteristic clinical features and a mutation not previously reported.

BACKGROUND: The eye is one of the most sensitive organs to sulfur mustard (SM) [C4H8Cl2S], and preliminary symptoms of exposure usually become evident in the eyes. In this study we aim to evaluate the possible long-term retinal electrophysiologic complications of SM poisoning in Iranian veterans during Iran-Iraq war (1980-1988). METHODS: In a cross-sectional study forty Iranian veterans who were exposed to mustard gas during the Iran-Iraq war (1980-1988) were included...

PURPOSE: To investigate the hypothesis that a new matrix therapy agent (ReGeneraTing Agent, [RGTA]) would speed up the corneal reepithelialization, improve stromal healing, and reduce ocular symptoms after epi-off corneal cross-linking (CXL). METHODS: Sixty eyes of 60 patients with progressive keratoconus were enrolled in the study. Epi-off accelerated CXL was performed in all patients. Sixty eyes were randomized into two groups according to use of RGTA eye drops prior to contact lens fitting at the end...

Purpose: To investigate the chromatic characteristics and intensity-response function of light-induced reflex lacrimation and its correlation with the melanopsin-driven postillumination pupil response (PIPR). Methods: Eleven visually normal participants completed the experiment. Lacrimation was measured in one eye by placing a calibrated filter paper strip in the conjunctival sac over a 1 minute-interval (Schirmer's test) during which participants received either no light stimulation (baseline trial) or one flash of blue or red light stimuli presented binocularly with a Ganzfeld stimulator, while the pupil response was recorded simultaneously from the fellow eye by using an eye tracker...

Thelazia callipaeda (Spirurida, Thelaziidae), the so-called oriental eyeworm, has been increasingly reported as an agent of infection in animals and humans from many European countries. Clinical signs range from subclinical to moderate or severe ocular disorders (e.g., epiphora, photophobia, conjunctivitis, keratitis, ulcers). The disease has been also diagnosed in animals from countries of the Balkan area (e.g., Croatia, Bosnia and Herzegovina and Serbia), but only a single case of canine thelaziosis, presumably autochthonous, was reported in Northern Greece...
