Hamartoma retiniano en esclerosis tuberosa – PDF Free Download
An astrocytic hamartoma is a benign tumour that arises from the enlargement and proliferation of astrocytes, which are supportive glial cells. They can present as an elevated, opaque, white nodule or as a flat and semi-translucent lesion with undefined margins. These lesions may be calcified or non-calcified.
Isolated, unilateral astrocytic hamartomas found in healthy individuals usually occur spontaneously. These lesions do not commonly progress or result in any complications. They are usually not associated with any other ocular findings and do not require any treatment. Multiple, bilateral or larger-sized retinal astrocytic hamartomas may retiniao systemically associated with neurocutaneous syndromes such as tuberous sclerosis and neurofibromatosis.
Rarely, astrocytic hamartomas can grow aggressively. This can result in exudative retinal detachments. In some cases, surgical interventions, radiation therapy or enucleation may be necessary.
Despite the isolated single nature of the astrocytic hamartoma in this case, given that this is a rare condition and there are potential systemic associations, referral to a retinal specialist for confirmation of diagnosis and management is recommended.
Usualmente no requieren tratamiento, excepto cuando existe un crecimiento excesivo que puede llevar al glaucoma neovascular, con dolor ocular y ceguera. The astrocytic hamartoma of the retina AHR or retinal astrocytoma is a glial tumor, benign and vascularized, which can be congenital or acquired.
Classically, it is related to tuberous sclerosis or neurofibromatosis, more specifically type 1.
More infrequently it can be found without systemic association. Both types, congenital and acquired, are similar ophthalmoscopically, except for the fact that the former rrtiniano present greater calcification.
They usually do not require treatment, except when there is excessive growth that can lead to neovascular glaucoma, with eye pain and blindness.
In these cases, enucleation is highly indicated. Deskgram is a powerful tool for telling a visual story about your brand. As social media users continue to demand more visual content, brands will need a platform where they can share photos that will visually engage their target audience.
