Fuchs spots are caused by regression of choroidal neovascularization. [3] Since it is a medical sign, treatment is given for the actual cause. Photothermal laser ablation, photodynamic therapy, anti-VEGF therapy, or a combination of these are the treatment options of choroidal neovascularization due to pathological myopia.
In many cases, myopia will stabilize once the growth process has been completed, but in more severe chronic cases, loss of vision can occur. Degenerative myopia, also known as malignant, pathological, or progressive myopia, is characterized by posterior sclera elongation and thinning (at least 25.5 mm to 26.5 mm) and high refractive errors of ...
Layers of the eye, with the choroid labelled. Choroidal neovascularization (CNV) is the creation of new blood vessels in the choroid layer of the eye.Choroidal neovascularization is a common cause of neovascular degenerative maculopathy (i.e. 'wet' macular degeneration) [1] commonly exacerbated by extreme myopia, malignant myopic degeneration, or age-related developments.
In myopia that is no longer progressing, the crescent may be asymptomatic except for its presence on ocular examination. However, in high-degree myopia, it may extend to the upper and lower borders, or form a complete ring around the optic disc and form a central scotoma. The myopic crescent is commonly seen in pathological axial myopia.
Cone dystrophy; Fundus of a 45 year-old patient with cone rod dystrophy segregating with a loss-of-function mutation (E1087X) in ABCA4. Note the presence of various-shaped pigment deposits in the posterior pole with atrophy of the retina, while the retina appears less damaged in periphery (upper part of the photograph).
Dilated fundus examination (DFE) is a diagnostic procedure that uses mydriatic eye drops to dilate or enlarge the pupil in order to obtain a better view of the fundus of the eye. [1] Once the pupil is dilated, examiners use ophthalmoscopy to view the eye's interior, which makes it easier to assess the retina , optic nerve head , blood vessels ...
High myopia usually describes myopia of −6.00 or more. [65] [84] People with high myopia are more likely to have retinal detachments [85] and primary open angle glaucoma. [86] They are also more likely to experience floaters, shadow-like shapes which appear in the field of vision. [87]
Multifocal choroiditis occurs mainly in myopic females. The fundus presents with yellow or gray lesions (white dots) at the level of the choroid and retinal pigment epithelium. The size of the white dots are between 50 and 500 micrometres and localized in the macula. The disease is characterized by vitritis and anterior chamber inflammation.
