The purpose of this study is to evaluate whether 7-day treatment with oral QLT091001 is safe, tolerable and can improve visual function in subjects with Leber Congenital Amaurosis (LCA) due to RPE65 or LRAT mutations.

The purpose of the study is to evaluate the safety and efficacy of an adeno-associated virus vector expressing RPE65 in patients with Leber congenital amaurosis caused by mutations in the ...
This study will deliver AAV2-hRPE65v2 vector to twelve subjects, age three or older; subjects will receive the vector via subretinal injection during surgery. The purpose of this research ...
To evaluate the natural history of visual function in subjects with IRD phenotypically diagnosed as Leber congenital amaurosis (LCA) or retinitis pigmentosa (RP) caused by RPE65 or LRAT ge...
The purpose of this study is to evaluate the safety and tolerability of QR-110 administered via intravitreal injection in subjects with LCA due to the CEP290 p.Cys998X mutation.

RPE65-associated Leber congenital amaurosis (RPE65-LCA) is an early-onset severe retinal dystrophy associated with progressive visual field loss. Phase I/II and III gene therapy trials have identified...
A 20-year-old male who was known to have Leber congenital amaurosis was assessed. Best-corrected visual acuity was counting fingers in both eyes (OU). Anterior segment OU revealed poorly reacting pupi...

Ocular gene therapy with recombinant adeno-associated virus (AAV) has shown vector-mediated gene augmentation to be safe and efficacious in the retina in one set of diseases (retinitis pigmentosa and ...
Thyroid hormone (TH) signaling has been shown to regulate cone photoreceptor viability. Suppression of TH signaling with antithyroid drug treatment or by targeting iodothyronine deiodinases and TH rec...
A rare degenerative inherited eye disease that appears at birth or in the first few months of life that results in a loss of vision. Not to be confused with LEBER HEREDITARY OPTIC NEUROPATHY, the disease is thought to be caused by abnormal development of PHOTORECEPTOR CELLS in the RETINA, or by the extremely premature degeneration of retinal cells.
Hereditary conditions that feature progressive visual loss in association with optic atrophy. Relatively common forms include autosomal dominant optic atrophy (OPTIC ATROPHY, AUTOSOMAL DOMINANT) and Leber hereditary optic atrophy (OPTIC ATROPHY, HEREDITARY, LEBER).
An ocular disease, occurring in many forms, having as its primary characteristics an unstable or a sustained increase in the intraocular pressure which the eye cannot withstand without damage to its structure or impairment of its function. The consequences of the increased pressure may be manifested in a variety of symptoms, depending upon type and severity, such as excavation of the optic disk, hardness of the eyeball, corneal anesthesia, reduced visual acuity, seeing of colored halos around lights, disturbed dark adaptation, visual field defects, and headaches.

Vascular diseases characterized by thickening and hardening of the walls of ARTERIES inside the SKULL. There are three subtypes: (1) atherosclerosis with fatty deposits in the ARTERIAL INTIMA; (2) Monckeberg's sclerosis with calcium deposits in the media and (3) arteriolosclerosis involving the small caliber arteries. Clinical signs include HEADACHE; CONFUSION; transient blindness (AMAUROSIS FUGAX); speech impairment; and HEMIPARESIS.
Impairment of the vestibular function of both inner ears which can cause difficulties with balance, gait, VERTIGO, and visual blurring.
Pediatrics is the general medicine of childhood. Because of the developmental processes (psychological and physical) of childhood, the involvement of parents, and the social management of conditions at home and at school, pediatrics is a specialty. With ...
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
