This paper presents a novel head-mounted point-of-care diagnostic system for detection and continuous monitoring of Age-related Macular Degeneration (AMD). This wearable embedded open-source platform enables accurate monitoring of AMD by taking advantage of multiple standard graphical interface techniques such as Amsler Grid, Threshold Amsler Grid, Macular Computerized Psychophysical Test and Preferential Hyperacuity Perimeter (PHP). Here, we describe the proposed multi-Grid or so-called NGRID software and elaborate on the hardware prototype...

The measurement of intraocular pressure (IOP) is an important vital sign for the eye, particularly for the diagnosis of glaucoma. Procedures for measuring IOP have been used by eye care professionals for over 100 years, but those without access to such professionals often go undiagnosed. We present a smartphone-based system that can be operated by minimally trained users to measure IOP. The system emulates fixed-force tonometry using a low-cost mechanical attachment to the smartphone. Video is captured through the attachment and then processed in real-time to provide an absolute estimate of the patient's intraocular pressure...

During toric intraocular lens (IOL) implantation, surgeons must take particular care to ensure that inaccurate preoperative measurement and intraoperative misalignment do not cause unexpected postoperative residual astigmatism. This retrospective, comparative case series study aimed to analyze the rotational deviation, or cyclotorsion, of three corneal marking methods: VERION digital marker (VDM; reference), horizontal slit beam marking (HSBM), and subjective direct visual marking (SDVM) on the table (using a bevel knife tip)...

The concept of value in radiology has been strongly advocated in recent years as a means of advancing patient care and decreasing waste. This article explores the concept of value creation in radiology and offers a framework for how radiology practices can create value according to the needs of their referring clinicians. Value only exists in the eyes of a customer. We propose that the primary purpose of diagnostic radiology is to answer clinical questions using medical imaging to help guide management of patient care...

BACKGROUND: Dexmedetomidine can facilitate a smooth extubation process and reduce the requirement of sevoflurane and emergence agitation when administrated perioperatively. We aimed to observe the extubation process and the recovery characteristics in pediatric patients undergoing tonsillectomy while anesthetized with either high-concentration sevoflurane alone or low-concentration sevoflurane combined with pre-medication of single dose of intravenous dexmedetomidine. METHODS: Seventy-five patients (ASA I or II, aged 3-7 years) undergoing tonsillectomy were randomized into three equal groups: to receive intravenous saline (Group D0), dexmedetomidine 1 μg/kg (Group D1), or dexmedetomidine 2 μg/kg (Group D2) approximately 10 min before anesthesia...

Contrary to Kidd and Castano (2013), Panero et al. (2016) fail to find that reading literary fiction improves performance on an advanced test of theory of mind (ToM), the Reading the Mind in the Eyes Test. However, this commentary shows that the findings presented in Panero et al. (2016) are not reliable due to two striking threats to the internal validity of their studies that were not clearly disclosed or discussed in the manuscript or supplementary materials. First, no effective strategy was implemented to ensure that participants read their assigned texts, and examination of the data revealed many participants whose reading times indicate that they were not exposed to the manipulation...

Binocular rivalry is a phenomenon in which perception spontaneously shifts between two different images that are dichoptically presented to the viewer. By elucidating the cortical networks responsible for these stochastic fluctuations in perception, we can potentially learn much about the neural correlates of visual awareness. We obtained concurrent EEG-fMRI data for a group of 20 healthy human subjects during the continuous presentation of dichoptic visual stimuli. The two eyes' images were tagged with different temporal frequencies so that eye specific steady-state visual evoked potential (SSVEP) signals could be extracted from the EEG data for direct comparison with changes in fMRI BOLD activity associated with binocular rivalry...

BACKGROUND: Early theories for cervical dystonia, as promoted by Hassler, emphasized the role of the midbrain interstitial nucleus of Cajal. Focus then shifted to the basal ganglia, and it was further supported with the success of deep brain stimulation. Contemporary theories suggested the role of the cerebellum, but even more recent hypotheses renewed interest in the midbrain. Although the pretectum was visited on several occasions, we still do not know about the physiology of midbrain neurons in cervical dystonia...

BACKGROUND: Glaucoma is a leading cause of irreversible blindness worldwide and the second most common cause of blindness after cataracts. The primary treatment for glaucoma aims to lower intraocular pressure (IOP) with the use of topical medicines. Topical medication instillation techniques, such as eyelid closure and nasolacrimal occlusion when instilling drops, have been proposed as potential methods to increase ocular absorption and decrease systemic absorption of the drops. OBJECTIVES: To investigate the effectiveness of topical medication instillation techniques compared with usual care or another method of instillation of topical medication in the management of glaucoma or ocular hypertension...

A 42-year-old male patient complaint with missing right eye was referred to the Department of Prosthodontics and Crown and Bridge. This patient was seeking artificial eye replacement. On careful clinical examination, a defect with a shrunken orbit and intact tissue bed was found in the patient. As the patient was economically very poor, modified stock ocular prosthesis was advised. To rehabilitate this ocular defect, "single" appointment technique with clinically available material was adopted, which is discussed in the present communication...

CASE REPORT: The case is presented on a patient with primary open-angle glaucoma treated with the novel ultrasound circular cyclocoagulation technique (UC3(®) [EyeTechCare, Rillieux La Pape, France]), who had previously undergone glaucoma surgery. Due to having extreme palpebral rigidity, worsened by the pre-operative local anesthesia injections, a canthotomy and cantholysis were needed to correctly position of the UC3(®) probe cone. Clinical outcome as regards the IOP and the surgical wound was very satisfactory...

When professional actors have been used in mental health simulations with nursing students, the experience has been regarded as a meaningful contribution to their education and described as a safe way of experiencing challenging situations that can occur in clinical settings. The aim was to study nursing students' reflections after meetings with nursing patients and their relatives, as enacted by professional actors, in psychiatric/elderly care. The design was a qualitative descriptive research approach. Gibbs's ( 1988 ) reflective cycle was the basis for the questions that were asked...
