Assessment of the Knowledge and Needs of Patients With AMD Before a Therapeutic Patient Education...

Age-related Macular Degeneration (AMD)

Age-related macular degeneration (AMD) is a disease that blurs the sharp, central vision you need for "straight-ahead" activities such as reading, sewing, and driving. AMD affects the macula, the part of the eye that allows you to see fine detail The purpose of the study is to describe in patients with AMD and depending on the nature of their pathology (neovascular or atrophic): (i) knowledge about their pathology (risk factors, symptoms, treatments, self-monitoring tool), (ii) their needs and (iii) impact on their daily lives This study is to make an inventory of the knowledge of patients with AMD about their disease and risk factors using a questionnaire (Appendix 1) and to identify their needs, the impact of the disease on their daily lives during individual interviews by raising the recurrent data and confronting them during the focus group. The information gathered will enable the construction of a therapeutic education program for better patient care and to strengthen the patient's capacities so that he becomes an actor in his change throughout his care project. This a 3 steps study: 200 patients will be enrolled and answer a questionnaire on knowledge of the disease Two groups of 20 patients will be selected to participate to a semi-structured individual interviews Two focus groups of 10 patients will be organized to assess needs, expectations, satisfactions or to better understand opinions, motivations or behaviors.

Safety Evaluation of China Patients: Long-term Treatment Outcome of Conbercept Ophthalmic Injection...

Wet Age-related Macular Degeneration (wAMD)

This is a post-marketing drug safety monitoring study in a prospective manner, and data collection will be performed in a registration-follow-up manner. Safety information about patients who have received intravitreal injection of Conbercept Ophthalmic Injection in medical institutions involved in the study during research will be actively monitored without intervening in diagnosis and treatment. All patients enrolled will be followed up for one year.

Implantation of Add on Lens for Age Related Macular Degeneration Patients With Low Vision

Inclusion Criteria

Age related macular degeneration (AMD) is the leading cause of vision loss in patients older than 55 years old. AMD can present as dry AMD or wet AMD. In most cases AMD affects both eyes although in many cases it's asymmetrical as far as severity. Some patients require low vision aids to continue their daily life tasks. In the past a few attempts were made to use low vision intraocular lenses with corrective glasses without enough success. In addition telescopic and prismatic lenses were also tried. The difficulties with these lenses included low field of vision, unsatisfactory magnification, complicated surgical technique and high complication rates. Recently an add on lens was designed for the sulcus for implantation in pseudophakic AMD patients. The add on lens doubles the magnification of the central image dependent on the reading distance and the anatomy of the eye. The lens is acrylic hydrophobic and designed for implantation in the sulcus either in pseudophakic patients or in addition to an intraocular lens implanted during a routine cataract surgery. The lens is 13 mm wide with 4 symmetric haptics. The lens has 1.5 mm central part of 10 diopters and the rest of the lens has no optical power. Our purpose is to study implantation of the lenses in AMD patients to improve their reading ability and to improve their daily living.

Association of Previously Verified Gene Polymorphisms With AMD in Turkish Population

Age-related Macular Degeneration

The purpose of this study is to determine whether common genetic polymorphisms that have been verified to be related to age-related macular degeneration (AMD) in some populations are also associated with AMD in Turkish population

Mitochondrial DNA in Vitreous Fluid and Blood in Patients With Eye Disease or Ocular Trauma.

Eye DiseasesOphthalmic Trauma4 more

This study is to characterize mitochondrial DNA (mtDNA) populations in adults with eye injuries and eye diseases. The eye exam is often hindered by the clouding of tissues involved in injury or disease. This protocol examines the use of mtDNA populations as indicators of developing inflammation and resolution of injury. This may be used to provide proactive treatment or define appropriate treatment needs beyond the indications of an ophthalmological exam.

Comparison Between Home Macular Perimeter and Optical Coherence Tomography (OCT) Visual Field Defects...

Age Related Macular DegenerationChoroidal Neovascularization

The FORESEE HOME is intended for the early detection of central and paracentral irregularities (abnormalities) in the visual field, most commonly associated with Age Related Macular Degeneration (AMD). However, the device has the ability to detect the development of the lesion post treatment and therefore to assess in determination of the next treatment. The Optical Coherence Tomography (OCT) may be used as well to identify choroidal neovascularization (CNV). Comparison between the two methods will allow better understanding of both devices. The FORESEE HOME can be used as an assessment tool for the progression and success of the treatment given to AMD lesions. Therefore, evaluating the size and the location of the treated lesions may serve as an additional tool.
