Glaucoma is a nonspecific term used for several ocular diseases that ultimately result in increased intraocular pressure (IOP) and decreased visual acuity. Acute angle-closure glaucoma (AACG) is an ocular emergency and receives distinction due to its acute presentation, need for immediate treatment, and well-established anatomic pathology.[1] Rapid diagnosis, immediate intervention, and referral can have profound effects on patient outcome and morbidity.
The acute angle closure literature has been plagued by the lack of a uniform definition and specific diagnostic criteria. Only in recent years has there been a strong push to standardize the definitions of the various forms of angle closure disease. Primary angle closure, primary angle-closure glaucoma, acute angle closure, and acute angle-closure glaucoma were previously used interchangeable. Now, acute angle closure is defined as at least 2 of the following symptoms: ocular pain, nausea/vomiting, and a history of intermittent blurring of vision with halos; and at least 3 of the following signs: IOP greater than 21 mm Hg, conjunctival injection, corneal epithelial edema, mid-dilated nonreactive pupil, and shallower chamber in the presence of occlusion.
Primary angle closure is defined as an occludable drainage angle and features indicating that trabecular obstruction by the peripheral iris has occurred (ie, peripheral anterior synechiae, increased IOP, distortion of iris fibers [iris whorling], lens opacities, excessive trabecular pigmentation deposits). An eye in which contact between the peripheral iris and the posterior trabecular meshwork is considered possible based on ocular anatomy is termed primary angle closure suspect. The term glaucoma is added if glaucomatous optic neuropathy is present.
What else can I help you with?
What are the trigonometric function of an acute angle?
The trigonometric functions are sine, cosine and tangent along with their reciprocals and the inverses. Whether the angle is acute or obtuse (or reflex) makes no difference).
How do you find sin of angle?
The sine of an angle is obtained from a right angle triangle. The other two angles are acute, or less than 90 degrees. The sin of the angle is the side opposite the angle divided by the hypotenuse.
What type of an angle is formed by the hands of a clock at 2 o'clock?
There are two angles: -- The small one is 60°, an acute angle. -- The big one is 300°, a reflex angle.
If an angle measure 270 degrees what kind of angle is it?
That's a reflex angle. 0 to <90 Acute angle 90 Right angle >90 to <180 Obtuse angle 180 Straight angle >180 to <360 Reflex angle 360 called Full circle
The two sides of a right triangle are of length 19 and 63 What is the measure of either of the acute angles in degrees?
Assuming that neither of the given sides is the hypotenuse, then if A is one of the acute angles, tan(A) = 19/63 So A = arctan(19/63) = 16.8 degrees. The other acute angle is 73.2 deg.
How many acute angles does a acute angle have?
1 acute angle = 1 acute angle
Sentence with acute?
That is an acute angle. An obtuse angle is not acute.
What is a 17 degree angle?
An acute angle
What angle is smaller than a right angle?
acute angle
Does an acute has 17 degrees?
An acute angle is an angle less than 90°. So an angle of 17° is an acute angle.
How many angles does a acute angle have?
An acute angle has one angle.
What type of angle is 35 degrees?
This is an acute angle.
Which is larger an acute acute or an obtuse angle?
Acute angle = <90 degrees Right angle = 90 degrees Obtuse angle = >90 degrees To answer your question, obtuse angle is larger.
Is the complement of an acute angle an acute angle?
A complement of an acute angle must be an acute angle. An acute angle is an angle whose measure is more than 0 degrees but less than 90 degrees. For example, even if the angle was the minimum 1 degree, the complement is still 89 degrees, which is still acute. Therefore, any combination of a complement of an acute angle MUST be acute.
Which angle is acute angle?
An angle less than 90 degrees is an acute angle.
What angle is 68?
An angle of 68 degrees is an acute angle
Is it true that every angle of an acute angle is acute?
yes. to be and acute angle, all angles must be acute. Obtuse angles only one angle has to be obtuse. Right angles only need one too. Acute has to have every angle to be acute, if one angle is obtuse or right, it's automatically no an acute Angle anymore.
