A number of other conditions and syndromes may present with infantile glaucoma, along with other ocular and/or systemic findings. [centogene.com]

  • Pallor

    Fundoscopy showed optic nerve head pallor, retinal vascular attenuation, macular staphylomata, varying degrees of pigmentary disturbance and white spots, all features recognised to lie within the clinical spectrum of LCA. [iovs.arvojournals.org]

    Examination of the posterior segment of the eye showed optic disc pallor, retinal vascular attenuation, varying degrees of macular staphyloma, widespread pigmentary disturbance heaviest equatorially and numerous fundal white spots. [nature.com]

    Most patients present optic disc pallor, vascular attenuation and pigmentary retinal changes. [wjgnet.com]

  • Progressive Loss of Vision

    LCA 10 leads to progressive loss of vision causing most patients to lose their sight in the first few years of life. To date, there are no treatments approved or products in clinical development that treat the underlying cause of the disease. [globenewswire.com]

  • Pendular Nystagmus

    Main clinical features congenital non evolutive blindness, with pendular nystagmus, anterior keratoconus, roving eye movements, absent ocular pursuit and eye poking, severe photophobia, hypermetropia, normal fundus at birth followed by salt and pepper [genatlas.medecine.univ-paris5.fr]

Early funding from the Foundation helped make this treatment possible. Treatments for forms of LCA caused by other mutated genes are in the development pipeline. [blindness.org]

Prognosis Nystagmus intensity (frequency x amplitude) often improves spontaneously with increasing age but depends on etiology. [emedicine.medscape.com]

However, we have also learned that along with the enzymatic dysfunction of RPE65 that disrupts the visual cycle, there is also degeneration of photoreceptors which continues after treatment and the long term prognosis remains guarded. [disorders.eyes.arizona.edu]

LCA has a very guarded prognosis, but it can be even worse when a complication such as coat’s like vasculopathy accompanies the case. [bmcresnotes.biomedcentral.com]

This will lead to better prognosis and treatment options for LCA patients. Currently, gene therapy for RPE65-LCA2 patients is a fact, and new similar emerging therapies will be soon available. [wjgnet.com]

In conclusion, systematic analysis of the full frequency spectrum of variation in the 15 selected genes not only gives us an overview of the molecular etiology of LCA in Chinese but also provides useful biomarkers for genetic counseling. [journals.plos.org]

Epidemiology Frequency United States In one US study, the annual incidence of pediatric nystagmus was estimated to be 6.72 per 100,000 persons younger than 19 years, with infantile nystagmus comprising 87% of the study patients. [2] Mortality/Morbidity [emedicine.medscape.com]

Pathophysiology Few patients are noted to have nystagmus onset at birth. The term infantile is probably more accurate than congenital and includes nystagmus that presents within the first 6 months of life. [emedicine.medscape.com]

Until now, however, little was known about the pathophysiology of the disease, but LCA is usually regarded as the consequence of either impaired development of photore-ceptors or extremely early degeneration of cells that have developed normally 9. [nature.com]

Gene therapy in LCA Recent advances in the knowledge of the genes and the pathophysiology associated with mutations in those genes, has opened a new era of mechanism-based molecular therapeutics in ophthalmology. [wjgnet.com]
