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...

BACKGROUND: Bowel length is an important factor in the management of patients with intestinal failure and short bowel syndrome (SBS). However, it is difficult to accurately measure the length of the small intestine. Our purpose was to demonstrate the feasibility of a dedicated software algorithm for calculating small intestine length based on magnetic resonance enterography (MRE) images. STUDY DESIGN: A custom algorithm for image thresholding, wall-identification, segmentation, and path extraction was designed and implemented...

Virtual reality has great potential in training road safety skills to individuals with low vision but the feasibility of such training has not been demonstrated. We tested the hypotheses that low vision individuals could learn useful skills in virtual streets and could apply them to improve real street safety. Twelve participants, whose vision was too poor to use the pedestrian signals were taught by a certified orientation and mobility specialist to determine the safest time to cross the street using the visual and auditory signals made by the start of previously stopped cars at a traffic-light controlled street intersection...

PURPOSE: To report the results of a 1-year follow-up analysis of the safety and efficacy of the Flexivue Microlens corneal inlay. METHODS: The Flexivue Microlens corneal inlay was implanted in the nondominant eye of patients with emmetropic presbyopia (a spherical equivalent of -0.5 to 1.00 diopter) after the creation of a 300-μm deep stromal pocket, using a femtosecond laser. The patients were followed up according to a clinical protocol involving refraction, anterior segment imaging analysis (Oculyzer), and optical quality analysis (OPD-Scan)...

Here we review the technical aspects of our experience with the neuroendoscopic bilateral nostril (binostril) transsphenoidal approach for pituitary adenomas. A total of 42 patients were treated in our hospital from September 2013 to December 2015. Total tumor resection was completed in 31 cases, nearly full resection was achieved in 9 cases, and partial resection was achieved in 2 cases. In most cases clinical symptoms were relieved after surgery. These included 18/22 cases with visual field and vision disorders; 19/25 cases with headaches; 11/15 cases where high baseline PRL returned to normal levels; 6/7 cases where elevated blood GH returned to normal levels; and 2/3 cases where elevated blood ACTH returned to normal levels after surgery...

Gait impairment is a core feature of Parkinson's disease (PD) which has been linked to cognitive and visual deficits, but interactions between these features are poorly understood. Monitoring saccades allows investigation of real-time cognitive and visual processes and their impact on gait when walking. This study explored; 1) saccade frequency when walking under different attentional manipulations of turning and dual-task; and 2) direct and indirect relationships between saccades, gait impairment, vision and attention...

OBJECTIVE: With anorexia nervosa (AN) having various presentations, attention has been directed towards particularly durable forms of the condition in both research and clinical contexts. A major hindrance in terms of advancing the field is the inconsistent labeling and defining of this subgroup. This has two implications; first, the inconsistent recruitment of participants when researching this sample, and second, the misdiagnosing of patients who may or may not have a durable course of the disease...

To reassure those concerned about wholesale discontinuity between human existence and posthumanity, transhumanists assert shared ground with antiquity on vital challenges and aspirations. Because their claims reflect key misconceptions, there is no shared vision for transhumanists to invoke. Having exposed their misuses of Prometheus, Plato, and Aristotle, I show that not only do transhumanists and antiquity crucially diverge on our relation to ideals, contrast-dependent aspiration, and worthy endeavors but that illumining this divide exposes central weaknesses in transhumanist argumentation...

Midas cichlid fish are a Central American species flock containing 13 described species that has been dated to only few thousand years old, a historical timescale infrequently associated with speciation. Their radiation involved the colonization of several clear water crater lakes from two turbid great lakes. Therefore, Midas cichlids have been subjected to widely varying photic conditions during their radiation. Being a primary signal relay for information from the environment to the organism, the visual system is under continuing selective pressure and a prime organ system for accumulating adaptive changes during speciation, particularly in the case of dramatic shifts in photic conditions...

REVIEW
E Mollo, M J Garson, G Polese, P Amodeo, M T Ghiselin
Covering: up to 2017The review summarizes results up to 2017 on chemosensory cues occurring in both aquatic and terrestrial environments. The chemicals are grouped by their physicochemical properties to compare their potential mobility in the different media. In contrast to what is widely asserted in the literature, the report emphasizes that living organisms encounter and sense molecules of various degrees of solubility and volatility both on land and in aquatic environments. The picture that emerges from the review suggests a substantial revision of the traditional definitions of the chemical senses based on their spatial range, which is currently orienting the literature on chemosensory signaling, in favor of a new vision based on the natural products that are the actual mediators of the chemosensory perceptions...

E J Volkers, R C J M Donders, A Algra, L J Kapelle
Transient monocular vision loss (TMVL) caused by temporary disturbance of blood flow to the retina is a harbinger of future vascular complications. The diagnosis may be difficult, not only because it is solely dependent on history taking, but also because the range of monocular visual symptoms a patient may experience is wide. The classic pattern of a sudden black or grey visual field, or a curtain that is drooping in front of one eye, easily fits in the diagnosis of TMVL; however, coloured vision or flashes should not always be considered as benign...

Population health outcomes are directly related to robust public health programs, access to basic health services, and a well-trained health-care workforce. Effective health services need to systematically identify solutions, scientifically test these solutions, and share generated knowledge. The World Health Organization (WHO)'s Global Healthcare Workforce Alliance states that the capacity to perform research is an essential factor for well-functioning public health systems. Low- and middle-income countries have greater health-care worker shortages and lower research capacity than higher-income countries...

The specific role of early visual deprivation on spatial hearing is still unclear, mainly due to the difficulty of comparing similar spatial skills at different ages and to the difficulty in recruiting young blind children from birth. In this study, the effects of early visual deprivation on the development of auditory spatial localization have been assessed in a group of seven 3-5 years old children with congenital blindness (n = 2; light perception or no perception of light) or low vision (n = 5; visual acuity range 1...

Multisensory-visual, vestibular and somatosensory information is integrated for appropriate postural control. The primary goal of this study was to assess somatosensory utilization during a functional motor task of unipedal postural control, in normal healthy adults. Assessing individual bias in the utilization of individual sensory contributions during postural control may help customization of rehabilitation protocols. In this study, a test paradigm of unipedal stance control in supine orientation with and without vision was assessed...

Paolo Bettin, Federico Di Matteo
Correct postoperative management is fundamental to prevent and treat complications and to optimize the success of filtering surgery. Timely control visits and appropriate actions and prescriptions ensure the best outcomes, allow recovery from a number of untoward events, and can reestablish filtration when failure seems imminent. In contrast, a slack follow-up and wrong interventions or prescriptions can lead to the failure of any surgery, no matter how accurately it was carried out, sometimes jeopardizing vision and even the anatomy of the globe...
