Modern retinal drug therapy is a result of the recent challenges and breakthroughs in chemistry, physics, genetics, cell biology and biotechnologies. Specific pharmaceutical and pharmacokinetic characteristics of a drug are of major importance and contribute to its ability to penetrate targeted ocular tissues in order to result in effective therapeutic concentrations. In addition, the drugs should maintain a prolonged time of activity and be safe with minimal local and systemic toxicity. The transporter vehicle or drug delivery system is crucial in order to enhance ocular tissue penetration and establish controlled drug release. Administration methods should be local, thereby reducing systemic side effects, and, ideally, treatment should be noninvasive. Within the group of so-called classic therapies, the use of pharmacologic treatments has become widespread for most severe retinal diseases. Thereby, ocular therapy of diseases like exudative age-related macular degeneration has improved markedly. Moreover, new metabolic pathways have been identified, new molecules have emerged, new synthesis technologies have been discovered, and new formulae conceived. These developments have opened new avenues for limiting disease progression.

To determine the significance of the correlation between optical coherence tomographic (OCT) findings and focal macular electroretinograms (fmERG) at 12 months after beginning intravitreal injections ...
To evaluate the clinical effectiveness of aflibercept in treatment of patients with neovascular age-related macular degeneration (nAMD).
What patients should eat to reduce their risk of age-related macular degeneration (AMD) is still unclear. We investigated the effect of a diet recommended by Health Councils on AMD.
Age-related macular degeneration (AMD) is the leading cause of blindness in industrialized countries. It is a multifactorial disease of the retina modified by environmental/individual (e.g. smoking) a...
Age-related macular degeneration (AMD) is the leading cause of blindness after 50 years in industrialized countries, compromising daily activities and reducing quality of life. And whose t...
AG-013,958 is being studied to treat patients with Age-Related Macular Degeneration. A total of 144 subjects may be enrolled in the trial. Subjects will be male or female at least 55 years...
Risk factors for Age-related Macular Degeneration (AMD) involves genetic variations in the alternative pathway of complement inhibitor factor H. The complement system is part of the innat...
The purpose of this study is to compare 12-month results of two single initial treatments—photodynamic therapy with verteporfin alone and this therapy combined with intravitreal bevacizu...
To assess the clinical course, prognosis, and risk factors of age-related macular degeneration (AMD) and cataract. To evaluate, in randomized clinical trials, the effects of pharmacologic...
A form of MACULAR DEGENERATION also known as dry macular degeneration marked by occurrence of a well-defined progressive lesion or atrophy in the central part of the RETINA called the MACULA LUTEA. It is distinguishable from WET MACULAR DEGENERATION in that the latter involves neovascular exudates.
Specialized ophthalmic technique used in the surgical repair and or treatment of disorders that include retinal tears or detachment; MACULAR HOLES; hereditary retinal disease; AIDS-related retinal infections; ocular tumors; MACULAR DEGENERATION; DIABETIC RETINOPATHY; and UVEITIS.
A retrogressive pathological change in the retina, focal or generalized, caused by genetic defects, inflammation, trauma, vascular disease, or aging. Degeneration affecting predominantly the macula lutea of the retina is MACULAR DEGENERATION. (Newell, Ophthalmology: Principles and Concepts, 7th ed, p304)
A prodromal phase of infection with the human immunodeficiency virus (HIV). Laboratory criteria separating AIDS-related complex (ARC) from AIDS include elevated or hyperactive B-cell humoral immune responses, compared to depressed or normal antibody reactivity in AIDS; follicular or mixed hyperplasia in ARC lymph nodes, leading to lymphocyte degeneration and depletion more typical of AIDS; evolving succession of histopathological lesions such as localization of Kaposi's sarcoma, signaling the transition to the full-blown AIDS.
A recombinant humanized monoclonal antibody fragment that binds VEGF-A to prevent its binding to VEGFR-1 and VEGFR-2 receptors. This activity reduces vessel permeability and angiogenesis in the treatment of neovascular age-related MACULAR DEGENERATION.
Ophthalmology is the branch of medicine that is devoted to the study and treatment of eye diseases. As well as mild visual defects correctable by lenses, ophthalmology is concerned with glaucoma, uveitis and other serious conditions affecting the eye, ...
Pharmacy is the science and technique of preparing as well as dispensing drugs and medicines. It is a health profession that links health sciences with chemical sciences and aims to ensure the safe and effective use of pharmaceutical drugs. The scope of...
