retinal tortuosity – retinal blood vessel tortuosity

 · Autosomal dominant syndrome of retinal arterial tortuosity is a rare condition often discovered after a benign macular hemorrhage Case report We report here the case of a 52-year-old man who was refereed to our center for an abrupt decrease in vision after an effort

This is an autosomal dominant condition as the result of heterozygous mutations in COL4A1 13q34, Mutations in the same gene have also been found in a simpler autosomal dominant disease known as Retinal Arteriolar Tortuosity 180000 , The latter may be an allelic condition or the same disorder,

Although retinal vessel tortuosity has been associated with retinopathy of prematurity and size at birth 18 19 whether early changes in retinal vessel tortuosity are related to cardiovascular risk factors in early life and are predictors of vascular disease in later life remains unclear, A recent study has suggested that ethnic differences in retinal vessel morphology may be an early sign of

Recognizing Abnormal Vasculature

All components of the nerve head are abnormally small including the entire disc area, the cup, and the neuroretinal rim, It has been reported that retinal vein tortuosity is predictive of patients with endocrinopathies, Retinal arteries often appear straight and narrow but this may not be seen in all cases, Visual acuity ranges from 20/50 to NLP but usually 20/200 or better, Many patients have nystagmus and strabismus,

 · Observable changes in retinal vascular architecture, such as increased retinal vein caliber decreased artery-to-vein ratio, retinal vascular tortuosity, increased prominence of the retinal arterial reflex, venous nicking, “copper” or “silver wire” appearance as well as the discovery of cholesterol, calcium or thrombotic emboli are all associated with concurrent and future cerebrovascular events, These associations …

Retinal Vessel Tortuosity Associated With Central Retinal

Background: The retinal vascular tortuosity can be a potential indicator of relevant vascular and non-vascular diseases However the lack of a precise and standard guide for the tortuosity evaluation hinders its use for diagnostic and treatment purposes This work aims to advance in the standardization of the retinal vascular tortuosity as a clinical biomarker with diagnostic potential allowing thereby the validation of objective …

Retinal Arteriolar Tortuosity

Increased tortuosity of the retinal blood vessels is usually evident in the first decade of life and may become more apparent with aging, Vision is usually normal but some individuals experience episodes of transient vision changes, These may be due to temporary small retinal hemorrhages that may follow even mild exercises, They usually disappear soon afterward without causing permanent damage

retinal vessel tortuosity

 · Familial retinal arteriolar tortuosity is a rare disorder with autosomal dominant inheritance It is characterized by a pathognomic pattern of progressive pronounced tortuosity of the arterioles of second and third order in the macular and peripapillary area developing during childhood or early adulthood The disorder can be complicated by intra- or preretinal hemorrhages that occur spontaneously or during physical exertion, …
