Three cases are presented spanning the spectrum of primary retinal telangiectasia. [ncbi.nlm.nih.gov]

It seems that the earlier age of presentation correlates with more severe disease course and progression. The presenting visual acuity also correlates with the long-term prognosis. [institut-vision.org]

Lipid-laden macrophages are present beneath and in the outer layers of the neural retina. [medtextfree.wordpress.com]

April 2017 Case Presentation A 54 year-old female was referred to Illinois Retina Associates for decreased vision and macular changes in both eyes. Her visual symptoms had been present for 5 years, but progressively worsening. [illinoisretina.com]

  Tuberous sclerosis (or Bourneville-Pringle disease) is associated with the ocular finding of adenoma sebaceum – butterfly-like vascularized red papulae on the skin of the nose and face or, possibly, in rare cases discoloured café au lait skin patches; [bmcophthalmol.biomedcentral.com]

• Arthritis

  Gass and Blodi (1993) postulate this category of disease to be related to systemic conditions, such as gouty arthritis or hypoglycemia (low blood sugar). [lowvision.preventblindness.org]

In these patients, treatment should be considered in case of documented progression. Argon laser photocoagulation is the treatment of choice in the early stages. [institut-vision.org]

While no treatment has been proven to prevent progression, treatment may be helpful in some cases. [rarediseases.info.nih.gov]

Repeated therapeutic laser or cryotherapy treatments may be required in eyes that have Coats’ disease. Most patients require at least two treatments. [medtextfree.wordpress.com]

Results of treatment with argon laser photocoagulation for proliferation have been variable, and it is not recommended because of the potential to trigger further neovascular growth and creation of scotomas in the treatment area, which are typically near [retinalphysician.com]

Therefore, no treatment was advised, and the patient remains with acuities of 20/100- in the right eye and 20/80- in the left. Initially, retinal signs can be subtle in type 2A IJRT, with no treatment being indicated. [ncbi.nlm.nih.gov]

IJRT prognosis depends on type and clinical features. Long-term prognosis for central vision is poor. [journals.lww.com]

The presenting visual acuity also correlates with the long-term prognosis. [institut-vision.org]

Prognosis The primary factors determining final visual outcome in patients with Coats' disease are the presenting visual acuity, extent of retinal detachment and the extent of macular exudation. [reviewofophthalmology.com]

Whilst Macular Telangiectasia type 2 can lead to significant visual loss in some cases, overall the prognosis is favourable, with average visual acuities of 6/12 being reported. [maculaspecialists.com.au]

The ultimate prognosis for eyes with Coats’ diseases can be measured in terms of two end points: visual acuity and anatomical stability. [medtextfree.wordpress.com]

Etiology and pathogenesis The etiology remains poorly understood. Recent data indicate the causative role of somatic mutation in the NDP gene. [institut-vision.org]

Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. [icd10coded.com]

They are organised into groups, and further divided into clinical, etiological or histopathological sub-types. [orpha.net]

Etiology The Mac Tel Project found a prevalence of diabetes mellitus (DM) of 28% and hypertension (HTN) of 52% in Mac Tel type 2. [eyewiki.aao.org]

Associations VATER syndrome The exact etiology is unknown and the disease is a non-hereditary disorder. [radiopaedia.org]

Epidemiology Coats disease is a very rare eye disorder. The exact prevalence is unknown. There is a clear male predominance (more than 75% of patients) and no ethnic predisposition. [institut-vision.org]

In 1915 Leber wrote two more articles and concluded that the disease he had described in 1912 was a variant of Coats’ disease.[2] EPIDEMIOLOGY Coats’ disease is characterized by discrete zones of alteration in the retinal vascular structure with aneurysmal [medtextfree.wordpress.com]

Coats' disease, Leber's miliary aneurysms, and IMT may be part of a singular clinical spectrum sharing pathophysiologic and histopathologic features and similarities in clinical presentation. [ncbi.nlm.nih.gov]

Pathophysiology IMT pathophysiology is incompletely understood. 1-11 IMT is categorized into types (IMT-1 and IMT-2), with each type subcategorized by various stages connoting characteristics. 1-11 Each subtype and stage takes into account the entity’ [reviewdiseasehandbook.com]

Pathophysiology Chronic neurodegenerative processes, vascular inflammation, occlusion and ectatic capillary changes lead to loss of outer retinal layers and formation of pseudolamellar macular holes with cysts or cavitations that can also be in inner [eyewiki.aao.org]

Thus, it is possible that the pathophysiology, including the involvement of VEGF, in the 2 types of IMT may be considerably different. Intravitreal bevacizumab treatment may rapidly improve retinal oedema in other diseases. [nature.com]
