#1
Aubrey R Tirpack, Jay S Duker, Caroline R Baumal
Importance: Intravenous drug abuse (IVDA) is a known risk factor for endogenous fungal endophthalmitis (EFE), a severe intraocular infection caused by hematogenous seeding of mycotic organisms to the eye. Reporting significant increases in heroin-related deaths since 2014, the New England region is in the midst of an opioid crisis that has led to a substantial increase in patients at risk for this vision-threatening disease. Objective: To present an update on characteristics, management, and visual outcomes in patients with EFE...

#2
Hugo Robles, Carlos Ciudad
The high extinction risk of small populations is commonly explained by reductions in fecundity and breeder survival associated with demographic and environmental stochasticity. However, ecological theory suggests that population extinctions may also arise from reductions in the number of floaters able to replace the lost breeders. This can be particularly plausible under harsh fragmentation scenarios, where species must survive as small populations subjected to severe effects of stochasticity. Using a woodpecker study in fragmented habitats (2004-2016), we provide here empirical support for the largely neglected hypothesis that floaters buffer population extirpation risks...

Roni Ostreiher, Aviad Heifetz
The sentinel behaviour of 38 Arabian babbler adult floaters, who lived alone within a territory belonging to a foreign group, was studied and compared with their own sentinel behaviour in the past, when they were group members. All floaters acted as sentinels and uttered 'alarm calls'. This suggests that sentinel activity is due at least, in part, to selfish motives. Floaters sentinelled less than they did as group members, with the decrease in sentinel activity sharper for ex-dominants than for ex-subordinates...

Background. This case highlights the importance of recognising multiple pathologies within the eye which may not necessarily be linked. Both birdshot retinochoroiditis and astrocytoma are rare conditions. The case underlines the need for early identification and treatment of birdshot retinochoroiditis with steroids and disease modifying drugs. Astrocytoma in the absence of tuberous sclerosis is also uncommon. Case Presentation. A 36-year-old male presented with 3-month history of bilateral progressive flashing lights and floaters...

Rowen van Eeden, D Philip Whitfield, Andre Botha, Arjun Amar
Understanding the ranging behaviours of species can be helpful in effective conservation planning. However, for many species that are rare, occur at low densities, or occupy challenging environments, this information is often lacking. The Martial Eagle (Polemaetus bellicosus) is a low density apex predator declining in both non-protected and protected areas in southern Africa, and little is known about its ranging behaviour. We use GPS tags fitted to Martial Eagles (n = 8) in Kruger National Park (KNP), South Africa to describe their ranging behaviour and habitat preference...

PURPOSE: Despite its off-label status, intravitreal bevacizumab is the most commonly used intraocular anti-vascular endothelial growth factor agent. Regulation of compounding pharmacies has recently increased to make compounded pharmaceuticals safer. Despite these changes, a marked increase in symptomatic, large silicone oil droplets following intravitreal bevacizumab injections was noticed. METHODS: Retrospective chart review was performed. Within a single private practice, patients who were noted to have large or symptomatic silicone oil bubbles after an intravitreal injection were reviewed...

In many animal species individuals compete for the sole possession of a breeding territory, whereas in other species communal territories are shared among same-sex conspecifics. Under what conditions does natural selection favor the evolution of individual territoriality, and under what conditions does it favor the evolution of sociality? We develop a self-consistent game-theoretic model that allows for feedbacks between evolutionary and population dynamics. In this model, nonresident floaters can chose between three strategies: they can wait for a territory vacancy to arise, they can try to forcefully take over an already-occupied territory, or they can share a territory with an established resident...

Zhong Lin, Nived Moonasar, Rong Han Wu, Robin R Seemongal-Dass
PURPOSE: Traditionally acceptable methods of anesthesia for vitrectomy surgery are quite varied. However, each of these methods has its own potential for complications that can range from minor to severe. The surgery procedure of vitrectomy for symptomatic vitreous floaters is much simpler, mainly reflecting in the nonuse of sclera indentation, photocoagulation, and the apparently short surgery duration. The use of 27-gauge cannulae makes the puncture of the sclera minimally invasive...

The effect of altered game formats on team performances during soccer practice can be harnessed by coaches to stimulate specific tactical behaviours. The aim of the present study was to analyse the influence of using (i) small goals [SG], (ii) goalkeepers [7G] and (iii) floaters [7GF] on the dispersion, shape and available space of teams during small-sided games (SSGs). Twenty-four male soccer players were distributed into four teams composed of five players, two goalkeepers and two floaters that performed six SSG bouts of 6 min, interspersed with 6 min of passive recovery...

Responsive wormlike micelles are very useful in a number of applications, whereas it is still challenging to create dramatic viscosity changes in wormlike micellar systems. Here we developed a pH-responsive wormlike micellar system based on a noncovalent constructed surfactant, which is formed by the complexation of N-erucamidopropyl-N,N-dimethylamine (UC22AMPM) and citric acid at the molar ratio of 3 : 1 (EACA). The phase behavior, aggregate microstructure and viscoelasticity of EACA solutions were investigated by macroscopic appearance observation, rheological and cryo-TEM measurements...

BACKGROUND: Non-infectious uveitis is a sight-threatening inflammatory disease that often necessitates prolonged use of high-dose corticosteroids, resulting in significant systemic side effects. There is a need for efficacious steroid-sparing immunomodulatory therapy for these patients, and the mTOR inhibitors (sirolimus and everolimus) may be contenders for this role. METHODS: A comprehensive review of preclinical and clinical research on mTOR inhibitors for non-infectious uveitis was performed...

Mamta Agarwal, Jambulingam Malathi, Jyotirmay Biswas
Frosted branch angiitis (FBA), a rare form of retinal vasculitis presenting as bilateral perivascular sheathing, resembling the appearance of frosted tree branches in winter, was first reported by Ito et al.(1) in 1976, in a young immunocompetent boy. FBA predominantly affects healthy young patients, the youngest reported in an 11-month-old infant(2) and oldest in a 42-year-old patient.(3) Classical symptoms include sudden onset of blurred vision with floaters and photopsiae. Fundus examination shows widespread perivascular translucent sheathing affecting both arterioles and venules, more commonly latter...
