she is new which means it would be best if we dilated her for comprehensiveness. new Pt ocular health = 92004, she will probably want a glasses rx = 92015

Transient elevated IOP refers to a temporary increase in intraocular pressure. Pressure on the orbit can cause compression of the eyeball, leading to an increase in IOP. Therefore, pressure on the orbit is a cause of transient elevated IOP.

you want to try to keep your CC as close to what the patient says, as close to their own words as you can. its ok to use abbreviations where appropriate. in this example, the patient did not elaborate on history of present illness until prompted, so including FOLDARS in the CC would be inappropriate.

The correct answer is 99213/99214 because these codes are used for evaluation and management (E/M) services for established patients. In this case, the patient is an established patient presenting for an eye wellness exam. The other codes listed are for specific eye procedures or exams, but they are not appropriate for this scenario.

this is end stage glaucoma very large cup

with pregnancy we want to avoid anesthetics if possible, of all the ways of tonometry icare and NCT do not need to utilize anesthetics. they are fast and inexpensive. ORA on the other hand is expensive

the ORA adjust for the error in measurement caused by CCT but it does not measure it, it uses the corneal hysteresis and resistance (viscoelastic response) values to account for CCT
a high CH leads to high CRF which is assumed to account for a thicker cornea.

The devices/instruments that utilize corneal applanation to measure tonometry are GAT (Goldmann applanation tonometer), Mackay-Marg tonometer (tonopen), NCT (Non-contact tonometer), Ocular Response Analyzer (ORA), and Perkins tonometer. These instruments apply pressure to the cornea to determine the intraocular pressure.

this question is really asking what vision insurance would cover (but that's too easy) vision insurance will cover "routine Vison related" tests. i like to think of it as, if the patient is benefiting/ getting something from the test somehow, then vision insurance will likely cover it (with an appropriate diagnosis ie. myopia, astigmatism etc). for a diagnostic refraction; you can do a refraction whenever the heck you want to: you dont always have to give the final Rx to the patient. when a refraction is done and no Rx is given, all the information still goes into the chart. so you may refer back at a later date to determine pertinent changes. But if the patient wants the Rx to get glasses, someone has to pay for that. gotta make that monayyy!

Rebound tonometry utilizes the method of ejecting a small plastic ball towards the cornea and measuring the rate and time of deceleration of the ball after hitting the cornea to measure IOP. This technique allows for non-contact measurement of intraocular pressure.

The Shiotz tonometer has the greatest effect on trabecular outflow during the process of measuring IOP. This is because the Shiotz tonometer works by applying a specific amount of force to the cornea, which causes deformation and a subsequent increase in intraocular pressure (IOP). This increase in pressure then leads to an increased outflow of fluid through the trabecular meshwork, which is responsible for draining fluid from the eye. Therefore, the Shiotz tonometer has the greatest effect on trabecular outflow compared to the other tonometers listed.

The correct answer is 92015, 92014. This is because during an eye wellness exam, the optometrist or ophthalmologist may perform a refraction test to determine the patient's prescription for glasses or contact lenses (CPT code 92015). They may also perform other pertinent related tests, such as a comprehensive eye exam (CPT code 92014), to evaluate the overall health of the patient's eyes. Therefore, both CPT codes 92015 and 92014 are appropriate to bill for this scenario.

The description provided in the question matches the condition known as oblique insertion. This condition refers to the malinsertion of the optic nerve head (ONH) through the scleral canal at an angle usually greater than 15 degrees. It can present unilaterally or bilaterally and is associated with elevation of the nasal rim tissue. The optic disk appears stretched and flattened temporally. Oblique insertion is commonly seen in individuals with myopia and astigmatism.

the reason why up and towards your nose is incorrect is because... we have two eyes, our nose is in the middle of said eyes. when you tell a patient to look towards their nose, they dont know which direction to look, its left for the right eye but right form the left eye, its just confusing. much easier to just tell the patient to look in a direction

Hollenhorst plaque is the most common plaque among the options given. It is a small, cholesterol-rich plaque that is typically found in the retinal artery. These plaques are often composed of cholesterol crystals and are known to cause blockages in the blood vessels, leading to decreased blood flow and potential damage to the surrounding tissues. This type of plaque is commonly associated with atherosclerosis and can be a significant risk factor for cardiovascular diseases.

Bright red blood is likely arterial because arterial blood is oxygenated and has a higher oxygen content, giving it a brighter red color. Dark red blood is likely venous because venous blood has a lower oxygen content and appears darker in color.

Gunn's sign refers to the presence of arterial sclerosis with associated venous deflection at a right angle. This means that there is a narrowing of the artery and the adjacent vein appears tapered. Additionally, the underlying vein is concealed. This sign is named after Dr. Robert Gunn, who first described it.

The question describes using a DO (dental operating microscope) to examine a lesion. The examiner first focuses on the apex (top) of the lesion and then adjusts the focus by dialing in 4 clicks to focus on the base (bottom) of the lesion. The question asks for the approximate relative height of the lesion. Since the examiner adjusted the focus by 4 clicks, it suggests that each click corresponds to a specific measurement. Therefore, the approximate relative height of the lesion would be 4 times the measurement of each click. The answer provided, 1.33mm, is the closest option to this calculation.

Vitreal hemorrhage and pre-retinal hemorrhage are the two types of hemorrhages that can obscure the view of the posterior pole. Vitreal hemorrhage refers to bleeding into the vitreous humor, the gel-like substance that fills the space between the lens and the retina. Pre-retinal hemorrhage, on the other hand, refers to bleeding that occurs between the retina and the vitreous humor. Both of these hemorrhages can obstruct the visual pathway and make it difficult to see the posterior pole of the eye, which includes the optic nerve head and the macula.

usually a bilateral congenital anomaly

A medium aperture would be suitable for measuring the patient's disc size. This is because a medium aperture allows for a balance between a narrow and wide opening, providing a moderate amount of light to enter the eye. This aperture size would enable the examiner to accurately assess the size of the patient's disc without overwhelming or insufficient light entering the eye.

Spontaneous venous pulsation is visible when the Intraocular Pressure (IOP) is higher than the central retinal venous pressure. This means that when the pressure inside the eye (IOP) is greater than the pressure in the veins of the retina, the veins will pulsate and become visible.

glaucoma is the best answer here, question asked about pathological (reason why large nerve is not correct)
Ocular hypertension does not mean glaucoma, yes high IOP put you at greater risk of developing glaucoma but high IOP is not glaucoma
high myopia goes along with large nerve

The red free filter allows the best visualization of ONH drusen. This filter enhances the contrast between the drusen and the surrounding tissue, making it easier to identify and visualize the drusen. The red free filter blocks red light, which can interfere with the visualization of drusen, while allowing other wavelengths of light to pass through, resulting in a clearer and more detailed image of the drusen.

The correct answer is "temporal < nasal < superior < inferior". This order is based on the general thickness of the optic nerve head rim tissue. The temporal region is usually the thinnest, followed by the nasal region, then the superior region, and finally the inferior region, which is generally the thickest.

some individuals have a bifurcation of the central retinal vein, if one gets occluded, all the blood drained out of that half of the retina through that vein is backed up and will leak. the other half of the retinal blood will drain normally
however a double branch vein occlusion is possible it is extremely unlikely to happen concomitantly

CHRPE (congenital hypertrophy of the retinal pigment epithelium) is a benign condition characterized by dark, well-defined spots on the retina. These spots can cause a window defect, which refers to a loss of transparency or a gap in the retinal pigment epithelium. This defect can result in a loss of visual function in the affected area. While CHRPE itself is not associated with malignancy or retinal edema, it can be associated with certain genetic disorders such as familial adenomatous polyposis (FAP), which increases the risk of colorectal cancer.

The correct answer is "proliferation of melanin in the pigmented epithelium - RPE hyperplasia" and "proliferation of melanin in the choroid - nevus". Melanin is a pigment that gives color to the skin, hair, and eyes. RPE (Retinal Pigment Epithelium) hyperplasia refers to the excessive growth of the pigmented epithelium in the retina, which can lead to an increase in melanin production. On the other hand, a nevus is a benign growth or mole that can occur in various parts of the body, including the choroid. In this case, the nevus leads to the proliferation of melanin in the choroid.

you cannot evaluate determine malignancy strictly based on original appearance, for a nevus, if you flip in a red-free filter, it should disappear. if it has grown past the choroid (malignant) then it will remain visible

Cotton wool spots are generally found at the layer of NFL (nerve fiber layer).

A defect in the retinal nerve fiber layer (RNFL) could result in more apparent/darker retinal vessels. The RNFL is responsible for transmitting visual information from the retina to the brain, and any damage or defect in this layer can affect the appearance of the retinal vessels. When the RNFL is compromised, the vessels may appear more prominent or darker due to changes in the surrounding tissue or blood flow.

In an eye with a central retinal artery occlusion (CRAO), several findings can be observed. A cherry red spot refers to a small area of the macula that appears red due to the contrast with the pale retina surrounding it. The pale retina is caused by a lack of blood flow to the area. Arteriole narrowing is also commonly observed as a result of the blockage in the central retinal artery. Poor vision is a typical symptom of CRAO due to the lack of blood supply to the retina. Additionally, retinal edema can occur as a consequence of the ischemia. Therefore, the correct answer includes cherry red spot, pale retina, arteriole narrowing, poor vision, and retinal edema.

A red-free filter is used in ophthalmology to enhance the visibility of certain structures in the eye by blocking out red light. It accentuates the contrast between different components of the eye, making them easier to distinguish. Choroidal melanoma, retinal nerve fiber layer, and blood vessels are all structures that can be accentuated by a red-free filter. However, choroidal nevi are not accentuated by this filter, meaning they do not stand out as much compared to the other structures.

Increasing the power of the condensing lens in SL biomicroscopy will increase the field of view (FOV) because a higher power lens allows for a wider area to be viewed. However, it will decrease the magnification because a higher power lens spreads out the light rays, resulting in a smaller image size.

The correct answer is OS inferior Branch retinal vein occlusion because the question states that the examiner noticed a specific finding in the patient's eye using a BIO (binocular indirect ophthalmoscope). Based on this finding, the examiner identified an occlusion in the inferior branch of the retinal vein in the left eye (OS). This indicates a blockage of the blood flow in the retinal vein, specifically in the inferior branch, leading to potential vision problems in the affected area.

In arteriosclerotic retinopathy, the stages indicate the severity of the condition. Stage IV is the most advanced stage, indicating severe arteriosclerosis and significant narrowing of the blood vessels in the superior arcade of the retina. This narrowing can lead to decreased blood flow and potential damage to the retina. Hence, stage IV is the correct answer as it suggests the highest level of severity in arteriosclerotic retinopathy in the superior arcade.

Hard exudates are yellowish-white deposits that can be seen in the retina of the eye. They are typically caused by leaking blood vessels and are composed of lipids, proteins, and cellular debris. While red blood cells (RBCs) can be present in hard exudates, they are not typically a major component. Therefore, the correct answer is RBC.

so the major indicator here is papilledema A,B, & D all have disc edema (fuzzy margins) so right away you should know at least grade IV. A,B,D all also have flame hemorrhages and CWS or hard exudates
C shows AV nicking (focal constriction) and arteriolar narrowing

An individual with stage 4 hypertensive retinopathy has a life expectancy of about 1 year. This is because stage 4 hypertensive retinopathy is a severe form of the condition, indicating significant damage to the blood vessels in the retina caused by high blood pressure. If left untreated, this can lead to complications such as retinal detachment and vision loss. Therefore, the prognosis for individuals with stage 4 hypertensive retinopathy is generally poor, with a limited life expectancy of approximately 1 year.

Bob has stage 3 hypertensive retinopathy based on the presence of severe arteriole narrowing with severe focal constriction, abnormal A/V crossing, macular star-patterned hard exudates, cotton wool spots, retinal edema, and flame heme. These findings indicate significant damage to the blood vessels in the retina, including narrowing, constriction, and abnormal crossing of arteries and veins. Additionally, the presence of hard exudates, cotton wool spots, retinal edema, and flame heme suggests the presence of retinal ischemia and hemorrhage, which are characteristic of stage 3 hypertensive retinopathy.

The correct answer is "break in ILM with subsequent proliferation of GCs or primary vitreal cells". This answer suggests that an ERM (Epiretinal Membrane) is associated with a break in the Internal Limiting Membrane (ILM) of the retina. This break can lead to the proliferation (increased growth) of Glial Cells (GCs) or primary vitreal cells. The explanation implies that the break in the ILM triggers a response in the cells, causing them to multiply or proliferate.
