What is RPE hypertrophy?
The retinal pigment epithelium (RPE) is a pigmented layer of the retina which can be thicker than normal at birth (congenital) or may thicken later in life. Areas of retinal pigment epithelial (RPE) hypertrophy usually do not cause symptoms. They are typically found during routine eye examinations.
What are bear tracks in the eye?
Bear tracks are congenital anomalies that are characterized by small, sharply circumscribed, variably sized, pigment spots. They are often grouped in one sector of the fundus. In our patient, they were predominantly located in the nasal retina, inferiorly in the right eye and superiorly in the left.
What is the difference between Chrpe and nevus?
CHRPE (congenital hypertrophy of the RPE) is also a benign pigmented ocular lesion. They are often much larger and more heavily pigmented than nevi. Despite their appearance, however, they cause no vision loss and have almost no potential to turn cancerous.
What is RPE changes in eye?
As the retinal pigment epithelium (RPE) ages, a number of structural changes occur, including loss of melanin granules, increase in the density of residual bodies, accumulation of lipofuscin, accumulation of basal deposits on or within Bruch’s membrane, formation of drusen (between the basal lamina of the RPE and the …
How do I find my RPE?
How do you measure RPE?
- Find your pulse on the inside of your wrist, on the thumb side.
- Use the tips of your first two fingers (not your thumb) and press lightly over the artery.
- Count your pulse for 30 seconds and multiply by two to find your beats per minute.
Are bear tracks in eyes common?
ANSWER: Bear tracks are small gray to black dots scattered on the retina at the back of the eye. Seen with an ophthalmoscope, they do resemble animal tracks. They are nothing but pigment deposits and don’t interfere with vision. They are rare, and the person is born with them.
What is congenital hypertrophy of the retinal pigment epithelium?
Congenital Hypertrophy of the Retinal Pigment Epithelium (CHRPE) CHRPE is a flat, darkly pigmented spot found in the back of your eye. It can vary in size, ranging from a few to more than 10 mm in diameter. They are composed of enlarged cells with densely packed and larger-than-normal, spherical pigment granules.
What is congenital hypertrophy of retinal pigment epithelium?
Congenital hypertrophy of the retinal pigment epithelium (CHRPE) is a rare benign lesion of the retina, usually asymptomatic and detected at routine eye examination. It results from a proliferation of pigmented epithelial cells, well defined, flat, does not cause visual symptoms if they do not reach the macula.
Which rest period length tends to be better for hypertrophy?
30-60 seconds
When the training goal is muscular hypertrophy, the combination of moderate-intensity sets with short rest intervals of 30-60 seconds might be most effective due to greater acute levels of growth hormone during such workouts.
