BACKGROUND: Migraineurs, in between headache attacks, have a different sensitivity to sensory motion stimuli compared to non-migraineurs. METHODS: This cross-sectional laboratory study examines the motion processing in migraineurs using ocular following responses (OFR) elicited by large field random dot patterns and open-loop smooth pursuit eye movements (PS) elicited by a single target moving on a homogenous background. Eye movements were recorded with a video-oculographic system (EyeSeeTec(®) ) and stimuli presented on a CRT at 100 Hz repetition rate to horizontal stimuli of a velocity of 2...

There are no standardized treatment protocols for pediatric non-infectious uveitis. Topical corticosteroids are the typical first-line agent, although systemic corticosteroids are used in intermediate, posterior and panuveitic uveitis. Corticosteroids are not considered to be long-term therapy due to potential ocular and systemic side effects. In children with severe and/or refractory uveitis, timely management with higher dose disease-modifying antirheumatic drugs (DMARDs) and biologic agents is important...

Custard apple seeds have been used as a traditional remedy for scalp infestation of lice and dandruff since many years in our part of the world. Not many people, doctors even, are aware about the ill effects of this practice. Surprisingly, there are very few reports on poisoning due to these seeds and the management is not very well streamlined. Rohit Shetty et al. highlighted the ill effects of the seeds and the need to avoid steroids in these cases as they worsen the clinical scenario. We present 2 patients who developed keratoconjunctivitis due to ocular exposure with custard apple seeds...

Transient receptor potential (TRP) channels are known to regulate energy metabolism, and TRPM8 has become an interesting player in this context. Here we demonstrate the role of the cold sensor TRPM8 in the regulation of clock gene and clock controlled genes in brown adipose tissue (BAT). We investigated TrpM8 temporal profile in the eyes, suprachiasmatic nucleus and BAT; only BAT showed temporal variation of TrpM8 transcripts. Eyes from mice lacking TRPM8 lost the temporal profile of Per1 in LD cycle. This alteration in the ocular circadian physiology may explain the delay in the onset of locomotor activity in response to light pulse, as compared to wild type animals (WT)...

Objectives The objective of this study was to investigate the effect of body position on intraocular pressure in clinically normal cats. Methods Sixteen clinically normal cats without any ocular abnormalities were used in this study. Cats were sequentially placed in three different recumbency positions (sternal recumbency, right lateral recumbency and dorsal position). For each of the three body positions, intraocular pressure (IOP) was recorded in the left eye using a Tono-Pen Vet tonometer (Reichert). Results Mean IOP readings in cats in the sternal recumbency, right lateral recumbency and dorsal positions were 15...

Measles, caused by the Morbilli virus, is a highly (about 95 %) contagious disease affecting primarily children, but without proper immunisation, adults can also be infected. The leading symptoms of the disease are high fever that presents after an incubation period of 9-10 days and the red rash that begins several days after the fever starts. Beyond specific generalized symptoms, measles may have ocular symptoms. The most commonly occurring conjunctivitis, the so-called "red eye symptom", is not characteristic only for measles infection, however, by taking the generalized symptoms it can suggest the diagnosis at the beginning of the disease...

Nitisinone, although unapproved for use in alkaptonuria (AKU), is currently the only homogentisic acid lowering therapy with a potential to modify disease progression in AKU. Therefore, safe use of nitisinone off-label requires identifying and managing tyrosine keratopathy. A 22-year-old male with AKU commenced 2 mg daily nitisinone after full assessment. He was issued an alert card explaining potential ocular symptoms such as red eye, tearing, ocular pain and visual impairment and how to manage them. On his first and second annual follow-up visits to the National Alkaptonuria Centre (NAC), there was no corneal keratopathy on slit lamp examination...

The vestibulo-ocular reflex (VOR) adaptation is an ideal model for investigating how the neurosteroid 17 beta-estradiol (E2) contributes to the modification of behavior by regulating synaptic activities. We hypothesized that E2 impacts VOR adaptation by affecting cerebellar synaptic plasticity at the parallel fiber-Purkinje cell (PF) synapse. To verify this hypothesis, we investigated the acute effect of blocking E2 synthesis on gain increases and decreases in adaptation of the VOR in male rats using an oral dose (2...

A 1-year-old, female domestic shorthair cat was presented with anorexia, depression and weight loss, accompanied by multifocal nodules affecting the face, pinnae and periarticular tissue. Routine medical treatments were ineffective. The animal's physical condition continued to deteriorate and it finally died. Post-mortem examination revealed multifocal to coalescing firm nodules with occasional ulceration affecting the ears, peri-ocular areas, nasal planum, oral cavity and laryngopharyngeal region. Tan-coloured, firm, nodular lesions were also observed in the periarticular tissue, lungs and tracheobronchial and mediastinal lymph nodes...

Koala retrovirus (KoRV) infection, thought to be associated with lymphoid neoplasia, and Chlamydia pecorum-related ocular and urogenital disease are both highly prevalent in eastern Australian koala (Phascolarctos cinereus) populations. However, in South Australian koalas, little is known about KoRV infection and C. pecorum-associated disease. We report the first South Australian case of lymphoma in a KoRV-A-positive female koala also affected by severe reproductive chlamydiosis. The koala was from the Mount Lofty Ranges population and was presented with hindlimb lameness...

REVIEW
Douglas A Jabs
The uveitides are a collection of more than 30 diseases characterized by intraocular inflammation. Many cases of juvenile idiopathic arthritis-associated uveitis, many cases of intermediate uveitis, and most cases of posterior and panuveitides requiring treatment are treated with corticosteroids and immunosuppression. Disease-specific, time-updated modeling of clinical data for several uveitides suggests superior prevention of ocular complications and visual outcomes with immunosuppression. These studies also suggest that oral corticosteroids at doses low enough for safe long-term therapy (i...

Assessment of ocular irritation is a regulatory requirement in safety evaluation of industrial and consumer products. Although a number of in vitro ocular irritation assays exist, none are capable of fully categorizing chemicals as stand-alone assays. Therefore, the CEFIC-LRI-AIMT6-VITO CON4EI (CONsortium for in vitro Eye Irritation testing strategy) project was developed to assess the reliability of eight in vitro test methods and computational models as well as establishing an optimal tiered-testing strategy...
