Active clinical trials for "Vision, Low"

The aim of the study is to assess accurancy of OCT angiography as a pronostic marker for patients undergoing neurosurgery for compressiver macroadenoma as compared with visual acuity, visual field and OCT.

During recent years, the interest in studying the risks of being born moderate-to-late preterm (MLP), defined as birth between gestational week 32 to 36, has increased. Today the investigators know that morbidity and mortality are significantly higher in these individuals compared to individuals born full-term. However, few studies have focused on the development of the eye in MLP individuals. The purpose of the study is to evaluate eye morphology and visual function in relation to growth, metabolism, blood pressure, neuropsychiatric factors, and quality of life in adolescents born MLP. The results of the examinations will be compared to an age-matched control group. The study will evaluate the structural, functional, and metabolic aspects of the eye with the hypothesis that early eye abnormalities may detect the risk of developing metabolic and cardiovascular diseases.

Primary objective of our study is to develop and validate a computer-based digital near-vision optotype based on the Greek version of the print MNREAD.

The aim of this study was to investigate the eye structure, visual impairment, visual motor development and motor coordination of children between 2-6 ages that had applied to diod laser photocoagulation and intravitreal anti - vascular endothelial growth factor treatment.

The aims of the Improving Communication with Formal/Informal Caregivers among Older Adults with Dual Sensory Impairment: Feasibility of Hearing Intervention in a Low Vision Rehabilitation Clinic (LVR) are: Primary aims Aim 1 To characterize prevalence of objective hearing impairment (i.e. DSI) among a clinical LVR population) in older adults (≥60 years) with English proficiency free from moderate to severe depression or cognitive decline using the Hearing Handicap Inventory for the Elderly (HHIE) assessment and an objective hearing evaluation. Aim 2 To describe the perceived burden of care on primary caregiver (identified people who assist with two or more activities of daily living. instrumental activities of daily living (ADLs/Instrumental activities of daily living (IADLs))of individuals with dual sensory impairment (DSI) among a clinical LVR population in older adults (≥60 years) with English proficiency free from moderate to severe depression or cognitive decline using the Zarit Burden Interview questionnaire and qualitative interview data analyses. Aim 3 To determine feasibility and benefit of a pilot manualized over-the-counter hearing intervention program on LVR patients to address communication among a DSI population using the Zarit Burden Interview questionnaire. 3A: Describe feasibility based on completion of pilot, drop-out rate, and semi-structured interviews 3B: Describe perceived communication improvements based on semi-structured interviews

The present research process is a prospective clinical study that will be conducted under the auspices of the Democritus University of Thrace (DUTH) in the open accommodation structure for refugees and immigrants of Kavala, Kavala, Greece, and the Pre-Removal Detention Center (PROKEKA) for Foreigners of Kos, Kos, Greece. The study aims to assess the basic ophthalmological condition of the refugee/immigrant population and is developed in two main areas: The recording of the ophthalmological care that the refugee/immigrant has received until his/her inclusion in the study through a structured questionnaire (eg previous examinations, spectacle utilization, pharmaceutical or other interventions, etc.) The measurement of monocular best-spectacle corrected visual acuity in both eyes using a web-based visual acuity chart. Adult participants living in the two aforementioned centers will be recruited in a consecutive-if-eligible basis. All age groups will be proportionally represented (proportional age distribution).

A multicentre, open-label, non-interventional study to observe treatment patterns in patients with wet age-related macular degeneration (wAMD), with visual impairment due to diabetic macular edema (DME), due to macular edema following retinal vein occlusion (RVO) or due to chorioidal neovascularization following pathologic myopia (mCNV) with repeated intravitreal injections of Lucentis® (Ranibizumab) including optional OCT monitoring over a 24 months observational period under real life conditions.

This study will provide a profile of blindness/visual impairment, avoidable blindness and cataract surgery service in Chaonan, mainland China. We also evaluate the diagnostic accuracy of Rapid Assessment of Avoidable Blindness (RAAB) comparison with conventional survey.

Primary objective of our study is to develop and validate an internet-based digital near and intermediate-vision reading test in the greek language.

OdySight is a mobile application allowing self-testing of visual parameters including near visual acuity and communication of the data to an online dashboard to patient's doctors. TIL-002 post-market clinical trial objective is to evaluate the near visual acuity at home, measured with OdySight application in comparison to the standardized methods. The clinical trial is intended to prove that OdySight can provide relevant data and participate in the remote monitoring of subject vision.
