#1
Abdul Rahman El-Khayat
A 35-year-old pregnant Caucasian woman at 27 weeks gestation presented with sudden onset painless loss of vision and a large floater in her left eye while doing yoga. She was found to have a dense vitreous haemorrhage with a small preretinal haemorrhage. Ultrasound imaging confirmed the haemorrhage and showed no other retinal damage. She was diagnosed with valsalva haemorrhagic retinopathy and was treated conservatively. After 5 months of follow-up, this woman had had a normal delivery and her haemorrhages and vision loss had resolved...

This case series describes a new optical coherence tomography (OCT) specific observation relevant to the differential diagnosis of patients with suspected optic neuritis. A tiny prefoveal floater, only detectable by OCT, was found responsible for the symptoms in three patients, one of whom had been referred with unilateral delayed visual evoked potentials. This case series suggests that with increased use of OCT in routine clinical care, entoptic phenomena can be demonstrated as a relevant differential diagnosis to optic neuritis...

BACKGROUND: The vitreous is the clear jelly of the eye and contains fine strands of proteins. Throughout life the composition of this vitreous changes, which causes the protein strands in it to bundle together and scatter light before it reaches the retina. Individuals perceive the shadows cast by these protein bundles as 'floaters'. Some people are so bothered by floaters that treatment is required to control their symptoms. Two major interventions for floaters include Nd:YAG laser vitreolysis and vitrectomy...

BACKGROUND: Injections of lipopolysaccharide in animal models generate acute anterior uveitis (also known as endotoxin-induced uveitis), but the effects of lipopolysaccharide injection are unknown in humans. We describe an unusual case in which acute anterior uveitis was dramatically activated subsequent to botulinum toxin injection in a patient with Behçet's disease but the acute anterior uveitis was satisfactorily attenuated by infliximab. CASE PRESENTATION: A 53-year-old Japanese man had normal ocular findings at his regularly scheduled appointment...

Hamouda Hamdy Ghoraba, Adel Galal Zaky, Mohamed Amin Heikal, Emad Eldin Mohamed Elgemai, Haithem Mamoun Abd Al Fatah
BACKGROUND: Silicone oil (SO) is used as an intravitreal tamponade agent in vitreoretinal surgery for rhegmatogenous retinal detachment (RRD) complicated by proliferative vitreoretinopathy or with large, multiple retinal tears. Usually, SO is left in the eye for at least 3 months. Although its use can lead to well-known complications, intraocular SO is generally well tolerated. Some studies have reported unexpected central vision loss after SO use or removal. OBJECTIVE: To investigate and analyze the reason for visual loss after the use or removal of intraocular SO in patients who underwent vitrectomy surgeries for RRD...

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...

#17
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...
