What is a Tigroid fundus?
Tigroid Fundus If the retinal pigment epithelium is not well pigmented, as in people with blond or red hair, then the underlying choroidal vessels may become strikingly visible. This is sometimes termed a tigroid fundus.
Is Tigroid fundus normal?
A normal fundus to which a deeply pigmented choroid gives the appearance of dark polygonal areas between the choroidal vessels, especially in the periphery.
What is a tessellated fundus?
Tessellated fundus is defined as the condition in which the choroidal vessels can be seen through the retina owing to reduced pigmentation or hypoplasia of the retinal pigment epithelium (RPE) [13.
What causes a tessellated fundus?
Due to myopia-related complications including myopic maculopathy and optic nerve damage, myopia may become one of the leading causes of irreversible vision impairment worldwide. Fundus tessellation is defined by increased visibility of the large choroidal vessels outside of the parapapillary beta zone.
What does Tigroid mean?
1 : having a striped or spotted appearance pathological changes in the eye resulted in a tigroid fundus. 2 : being or consisting of Nissl substance.
What are Foster Fuchs spots?
Fuchs spots (also referred to as Forster-Fuchs spots) is an area of RPE hyperplasia suspected to be the response of the RPE to previous regressed CNV. Myopic CNV is the most common cause of vision loss in high myopia and has been reported in 5% to 10% of cases of pathologic myopia.
Can pathological myopia be treated?
Treatment. There is currently no cure for pathological myopia. Individuals with stable high myopia will be followed up regularly for visual acuity, refraction, and general ophthalmic health. With glasses or contact lenses stable high myopathy can be corrected by altering the way in which light rays bend in the eye.
Do Roth spots go away?
There’s no specific treatment for Roth spots, since a variety of conditions can cause them. However, once the underlying condition is treated, Roth spots usually go away on their own.
Can I go blind from myopia?
Left untreated, high myopia complications can lead to blindness, so regular eye exams are critical. Degenerative myopia: A fairly rare but serious form that usually begins in early childhood is degenerative myopia. This form is severe because it damages the retina and is a leading cause of legal blindness.
What is tigroid fundus?
TIGROID FUNDUS [Photo Courtesy of Co-Author of this article: Antonio Chirumbolo]: As the eye enlarges, the retinal pigment epithelium thins, resulting in a tessellated (checkered) appearance of the fundus and increased visibility of the choroidal vasculature.
What are the signs and symptoms of tigroid fundus myopia?
Affected females have high myopia with a tigroid fundus and temporal crescent of the optic nerve. The eyes have an axial length of greater than 26 mm and a spherical refraction of -6 diopters or greater which are present before the age of 7 years. No systemic abnormalities have been found in this condition.
Why do we take photographs of the ocular fundus?
10 A photograph allows clinicians to evaluate the ocular fundus more easily, to emphasise the importance of the ocular fundus examination in the complete evaluation of many classes of neurological disease, and to point out key features of the ocular fundus to trainees in the context of an actual patient’s evaluation.
What is non-mydriatic fundus photography?
Non-mydriatic fundus photography is an effective alternative to direct ophthalmoscopy for examining the ocular fundus in non-ophthalmology settings. Even without additional training, it is easier to detect and interpret abnormalities of the ocular fundus with photographs rather than with direct ophthalmoscopy.
