4. What are you likely to see on the palpebral conj with bacterial, allergic, toxic, VKC, SLK or any chronic irritation?

Explanation

In cases of bacterial, allergic, toxic, VKC (vernal keratoconjunctivitis), SLK (superior limbic keratoconjunctivitis), or any chronic irritation of the palpebral conjunctiva, one is likely to observe the presence of papillae. Papillae are small, raised bumps or nodules that can develop on the conjunctiva as a result of inflammation and irritation. They are commonly seen in these conditions and can vary in size and appearance.

14. This is an example of ______.

Explanation

Ecchymosis refers to the discoloration of the skin caused by bleeding underneath, typically due to broken blood vessels. It appears as a purplish or bluish bruise-like mark on the skin. Therefore, the correct answer is ecchymosis.

Submit
15. Lymphandeopathy (lymph node disease or swollen/enlarged lymph nodes) is indicative of _____ disease.

Explanation

Lymphadenopathy, or swollen lymph nodes, is commonly associated with viral infections. When the body is infected with a virus, the immune system responds by activating the lymph nodes, causing them to swell. This is because lymph nodes contain immune cells that help fight off infections. Therefore, the presence of lymphadenopathy suggests that the underlying cause is likely a viral disease.

Submit
16. Episcleritis, pingueculitis, inflamed ptyergium, phylectenulosis, and FBs will have what type of pattern of injection?

Explanation

sectoral: redness confined to one area of the conj

Submit
17. Viral, chlaymidial and toxic offenses will result in what type of elevation on the conj?

Explanation

Viral, chlamydial, and toxic offenses can cause an elevation on the conjunctiva, specifically on the follicles. Follicles are small, raised bumps that can develop on the conjunctiva in response to inflammation or infection. This elevation is a common sign of these types of offenses and can help in their diagnosis.

Submit
18. A pt comes into the office with a red eye and miotic pupils.  What is the likely ddx?

Explanation

iritis: inflammation of the uveal tract

Submit
19. A pt comes into the office with a red eye and fixed, mid-dilated pupils.  What is the likely ddx?

Explanation

The likely diagnosis for a patient presenting with a red eye and fixed, mid-dilated pupils is angle closure. Angle closure refers to a condition where the drainage angle of the eye becomes blocked, leading to increased intraocular pressure. This can result in symptoms such as redness of the eye and fixed, mid-dilated pupils. Prompt medical attention is necessary to prevent further complications.

Submit
20. Upon further eval of your red eye pt, you notice diffuse, beefy engorged vessels that are most prominent in the fornices of the conj.  What is the possible cause?

Explanation

The presence of diffuse, beefy engorged vessels in the fornices of the conjunctiva suggests a bacterial infection as the possible cause. Bacterial conjunctivitis is characterized by the inflammation of the conjunctiva, resulting in redness and swelling of the blood vessels. This type of infection is commonly caused by bacteria such as Staphylococcus aureus or Streptococcus pneumoniae. Viral conjunctivitis, on the other hand, typically presents with watery discharge and is often associated with a viral respiratory infection. Trauma and herpes may also cause redness in the eye, but the presence of engorged vessels points towards a bacterial infection.

Submit
21. Upon examining your pt, you notice that the conj appears to have a faint blue tint and the vessels are criss crossing.  What do you think is the most likely dx?

Explanation

The presence of a faint blue tint and criss-crossing vessels in the conjunctiva suggests scleritis. Scleritis is an inflammation of the sclera, the white part of the eye, which can cause a bluish discoloration and engorgement of blood vessels. Uveitis refers to inflammation of the uvea, the middle layer of the eye, and typically presents with other symptoms such as eye pain and sensitivity to light. Episcleritis is a milder form of eye inflammation that does not typically cause a blue tint or vessel criss-crossing. HZK refers to herpes zoster keratitis, which is a viral infection of the cornea and would not present with the described symptoms.

Submit
22. Follicles that a central vessel running to the surface

Explanation

Papillae have central vessels --> red bumps
Follicles have no central vesslels, but still may have vessels on surface --> yellow/white bumps

Submit
23. Follicles are larger than papillae

Explanation

Papillae: 0.1-0.2 mm
Follicles: 0.5-1.0 mm

Follicles are 5x as large as papillae

Submit
24. Pseudomembrane removal theoretically should not bleed

Explanation

Pseudomembrane removal theoretically should not bleed because pseudomembranes are not composed of blood vessels. They are a layer of dead cells and fibrin that forms on the surface of tissues, typically as a result of infection or inflammation. Therefore, removing pseudomembranes should not cause any bleeding.

Submit
25. Phenylephrine or other vasoconstrictors are appropriate to manage chemical burns because they will prevent the spread of the chemical do deeper ocular structures

Explanation

Phenyl should NEVER be administered in chemical burn situations because you want blood to be able to reach the injured area

Submit
26. Chronic herpes simplex keratitis will result in reduced corneal sensitivity

Explanation

**However, the first episode or acute HSK will NOT RESULT IN REDUCED CORNEAL SENSITIVITY

Submit
27. What part of the nervous systems are you testing during the cotton wisp test?

Explanation

The cotton wisp test is used to assess the sensitivity of the cornea and the ophthalmic branch of the trigeminal nerve. The ophthalmic branch of the trigeminal nerve is responsible for providing sensory innervation to the forehead, scalp, and the front part of the head. By gently touching the cornea with a cotton wisp, the test evaluates the integrity of the ophthalmic branch of the trigeminal nerve and its ability to transmit sensory information from the cornea to the brain.

Submit
28. Staph, strep and pseudomonas are the most common types of microbes associated with bacterial keratitis

Explanation

Staph, strep, and pseudomonas are indeed the most common types of microbes associated with bacterial keratitis. Bacterial keratitis is an infection of the cornea caused by bacteria, and these three types of bacteria are frequently found to be the causative agents. Staphylococcus aureus and Streptococcus pneumoniae are the most common types of staph and strep bacteria associated with this condition, while Pseudomonas aeruginosa is the most common type of pseudomonas bacteria. Therefore, the statement that Staph, strep, and pseudomonas are the most common types of microbes associated with bacterial keratitis is true.

Submit
29. The correct ORDER for collecting a specimen is: 1) cornea 2) conj 3) lids

Explanation

Correct order: 1) lids 2) conj 3) cornea

Submit
30. Pseudomembranes are caused by _____ infection

Explanation

Pseudomembranes are caused by adenoviral infection, specifically by the adenovirus. Adenoviruses are a group of viruses that can cause a wide range of respiratory, gastrointestinal, and eye infections in humans. When adenoviral infection occurs, it can lead to the formation of pseudomembranes, which are thick, grayish-white membranes that develop on the affected tissues. These pseudomembranes can cause symptoms such as difficulty breathing, swallowing, or seeing, depending on the location of the infection. Therefore, adenoviral infection is the correct explanation for the presence of pseudomembranes.

Submit
31. What is the only disease discussed in lecture that will result in VISIBLE lymph nodes?

Explanation

Ocular glandular syndrome is the only disease discussed in the lecture that will result in visible lymph nodes. This suggests that the disease affects the lymphatic system, causing the lymph nodes to become enlarged and noticeable. The other options, PFC, HSV, and orbital cellulitis, do not specifically mention any involvement of the lymph nodes, making ocular glandular syndrome the correct answer.

Submit
32. Which of the following disease will most likely produce the most pus?

Explanation

Hyperacute conjunctivitis is the most likely disease to produce the most pus. Conjunctivitis is an inflammation of the conjunctiva, the thin clear tissue that lines the inside of the eyelid and covers the white part of the eye. Hyperacute conjunctivitis refers to a severe and rapidly progressing form of conjunctivitis. In this condition, there is a significant amount of discharge from the eye, which may contain pus. The presence of pus indicates a bacterial infection, which is more common in hyperacute conjunctivitis compared to other types of conjunctivitis.

Submit
33. Viral, scleritis, corneal ulcer, blepharoconjunctivitis, HSK, HZK, and toxic conjunctivitis will most likely present as:

Explanation

The correct answer is "diffuse injection of the entire conj." Viral, scleritis, corneal ulcer, blepharoconjunctivitis, HSK, HZK, and toxic conjunctivitis are all conditions that can cause inflammation of the conjunctiva, the clear membrane that covers the white part of the eye. This inflammation typically leads to redness and injection of blood vessels in the conjunctiva. The term "diffuse injection" refers to widespread redness throughout the entire conjunctiva. Therefore, diffuse injection of the entire conjunctiva is the most likely presentation for these conditions.

Submit
34. Gonio should be performed before IOPs because checking IOPs can affect the visibility of angle structures

Explanation

Gonio should be performed AFTER IOP measurement bc gonio can affect IOP

Submit
35. The RPS Adeno Detector is used to determine if a red eye is secondary to ______

Explanation

The RPS Adeno Detector is used to determine if a red eye is secondary to a virus. This suggests that the device is specifically designed to detect the presence of viral infections in the eye, helping healthcare professionals diagnose and treat the condition accurately.

Submit
36. What is the most common type of corneal dystrophy?

Explanation

Epithelial basement membrane dystrophy (EBMD) is the most common type of corneal dystrophy. This condition affects the outermost layer of the cornea, called the epithelium, and the basement membrane that supports it. EBMD is characterized by the formation of abnormal deposits and irregularities on the cornea, leading to symptoms such as blurred vision, dryness, and discomfort. It is typically a non-progressive condition that can be managed with lubricating eye drops and other supportive measures.

Submit
37. The average force measured with Cochet and Bonnet's aesthesiometer is ____ grams/mm2

Explanation

The average force measured with Cochet and Bonnet's aesthesiometer is 11.8 grams/mm2.

Submit
38. You notice in your red eye pt that their vessels appear like corkscrews...what is this most likely associated with?

Explanation

The presence of corkscrew-like vessels in the eye is most likely associated with a carotid cavernous sinus fistula. This condition occurs when there is an abnormal connection between the carotid artery and the cavernous sinus, a vein-filled cavity at the base of the skull. This connection causes an increased blood flow to the eye, leading to the appearance of twisted vessels. Other options like severe allergic reaction, toxic conjunctivitis, and episcleritis do not typically cause this specific vascular abnormality.

Submit
39. If you suspect a bacterial etiology for a staining pattern, you might want to take a culture of the eye before you instill any diagnostic or therapeutic agents.

Explanation

If there is a suspicion of a bacterial infection causing the staining pattern in the eye, it is important to take a culture before applying any diagnostic or therapeutic agents. This is because the culture will help identify the specific bacteria causing the infection, which can then guide the appropriate choice of treatment. Applying agents before taking a culture may interfere with the growth of bacteria, making it difficult to obtain accurate results. Therefore, it is necessary to take a culture first to ensure proper diagnosis and treatment.

Submit
40. What is a QUANTITATIVE MEASURE of corneal sensitivity?

Explanation

Cochet & Bonnet's aesthesiometer is a quantitative measure of corneal sensitivity. It is a device that measures the minimum amount of pressure required to elicit a response from the cornea. This measurement provides an objective and numerical value of corneal sensitivity, allowing for more accurate assessment and monitoring of corneal health. The other options, cotton wisp and poking the eye with a finger, are subjective measures and do not provide a quantitative value.

Submit
41. In Cochet & Bonnet's, a shorter thread is correlated with lower sensitivity.

Explanation

shorter thread = more pressure = less sensitive cornea

Submit
42. Your pt comes in with an ulcer that appears whitish-grey with feathery borders.  You also notice sateline infiltrates as well.  What is the likely cause of their condition?

Explanation

This is describing a FUNGAL ULCER (candida, fusarium, aspergillus)

Submit
43. When should a cotton swab NOT be used to collect a specimen?

Explanation

A cotton swab should not be used to collect a specimen from the cornea because the cornea is a sensitive and delicate part of the eye. Using a cotton swab can potentially cause damage or irritation to the cornea, leading to further complications or discomfort for the patient. Therefore, alternative methods should be used to collect a specimen from the cornea that are safer and less invasive.

Submit
44. Follicles are most marked in the upper tarsal conj

Explanation

Follicles --> LOWER tarsal conj

Submit
45. A pt comes into the office with a red eye and irregular, fixed pupils.  What is the likely ddx?

Explanation

The likely ddx (differential diagnosis) for a patient presenting with a red eye and irregular, fixed pupils is posterior synechiae. Posterior synechiae refers to the adhesion between the iris and the lens, which can cause the pupil to become irregular and fixed. This condition is often associated with inflammation or infection in the eye, such as uveitis or iritis. It is important to further evaluate the patient to determine the underlying cause and provide appropriate treatment.

Submit
46. Which diseases most likely result in circumlimal injection?

Explanation

Circumlimbal injection refers to the dilation of blood vessels around the limbus of the eye. Uveitis, which is the inflammation of the uvea (middle layer of the eye), can cause circumlimbal injection due to the increased blood flow to the affected area. Angle closure, on the other hand, refers to the narrowing or closure of the drainage angle in the eye, leading to increased intraocular pressure. This increased pressure can also result in circumlimbal injection. Therefore, both uveitis and angle closure are likely to cause circumlimbal injection.

Submit
47. Indicate the possible causes of true membranes.

Explanation

True membranes can be caused by various factors such as infections, autoimmune reactions, or physical trauma. In the case of gonorrhea, the infection can lead to the formation of true membranes as the body's immune response attempts to contain and eliminate the bacteria. Stevens-Johnson syndrome, a severe allergic reaction, can also cause the development of true membranes as a result of the body's immune system attacking its own tissues. Chemical or thermal burns can damage the skin or mucous membranes, leading to the formation of true membranes as part of the healing process.

Submit
48. Indicate what conditions can lead to EOM restriction.

Explanation

Conditions such as Grave's Disease, Orbital cellulitis, and trauma can lead to EOM (Extraocular Muscle) restriction. Grave's Disease is an autoimmune disorder that affects the thyroid gland and can cause inflammation and swelling of the eye muscles, leading to limited eye movements. Orbital cellulitis is a bacterial infection of the tissues surrounding the eye, which can result in inflammation and scarring of the eye muscles, causing restriction of eye movements. Trauma, such as fractures or injuries to the eye socket or surrounding structures, can also lead to EOM restriction due to damage or displacement of the eye muscles.

Submit
49. An infant with viral infection will have ____.

Explanation

viral infections usually cause follicles, but infants are not old enough to form follicles

Submit
50. Which diseases are associated with palpable, NON-TENDER lymph nodes? choose all that apply.

Explanation

Palpable, non-tender lymph nodes are commonly associated with infections, inflammation, or malignancies. PFC (preauricular follicles) and inclusion conjunctivitis are both viral infections that can cause swollen lymph nodes. PFC is caused by the Epstein-Barr virus, while inclusion conjunctivitis is caused by the Chlamydia trachomatis bacteria. On the other hand, EKC (epidemic keratoconjunctivitis), hyperacute conjunctivitis, and preseptal cellulitis are not typically associated with palpable, non-tender lymph nodes.

Submit
51. Which diseaes can result in a sub-conj heme? Choose all that apply.

Explanation

A sub-conj heme refers to a subconjunctival hemorrhage, which is bleeding underneath the conjunctiva, the clear membrane that covers the white part of the eye. Trauma can cause a sub-conj heme by directly injuring the blood vessels in the eye. The Valsalva maneuver, which involves forcefully exhaling against a closed airway, can increase pressure in the blood vessels and potentially cause them to rupture. Blood that is too thin, often due to certain medications or medical conditions, can make the blood vessels more prone to bleeding. Hypertension, or high blood pressure, can also increase the risk of blood vessel rupture and subsequent sub-conj heme.

Submit
52. What oral antibiotic can be give for chemical burns to reduce inflammation and help the epithelium heal quicker?

Explanation

Doxycycline is a broad-spectrum antibiotic that has anti-inflammatory properties. It can help reduce inflammation caused by chemical burns and promote faster healing of the epithelium. The recommended dose of doxycycline for this purpose is 100 mg twice a day. Tetracycline and erythromycin are also antibiotics, but they may not be as effective in reducing inflammation and promoting healing in chemical burns as doxycycline.

Submit
53. KKC has systemic involvement and will present with cough, fever etc.

Explanation

EKC --> no systemic involvement
PCF --> systemic involvement

Submit
54. A pt comes into the office with a red eye and upon pupil testing you note an APD.  What is the likely ddx?

Explanation

The likely ddx (differential diagnosis) for a patient with a red eye and an afferent pupillary defect (APD) includes orbital cellulitis and endophthalmitis. Orbital cellulitis is an infection of the tissues surrounding the eye, while endophthalmitis is an infection within the eye. Both conditions can cause redness of the eye and an APD. Angle closure, which refers to a blockage of the drainage angle in the eye, is not likely to cause an APD. Therefore, the correct answer is "a and c" (orbital cellulitis and endophthalmitis).

Submit
55. Match the type of red eye culprit with the type of discharge is it associated with
Submit
56. Ring ulcers are caused by:

Explanation

Central + Peripheral ulcers due to bacteria + fungi

Keratitis ulcers due to herpes

Submit
57. What would be the best option if you needed to remove a lot of lashes due to trichiasis?

Explanation

Cryotherapy would be the best option for removing a lot of lashes due to trichiasis. Cryotherapy involves the use of extreme cold temperatures to freeze and destroy abnormal tissues, including the lashes in this case. It is a non-invasive procedure that can effectively remove the lashes without causing significant damage to the surrounding area. Epilation, electrolysis, and radio frequency ablation are not suitable options for removing lashes in this scenario.

Submit
58. Match the type of SPK with the causes.
Submit
59. Mark all the possible causes of a blown pupil.

Explanation

Blown pupil refers to a dilated and non-reactive pupil, which can be caused by various factors. Trauma can lead to a blown pupil due to damage to the nerves controlling the pupil's constriction. Anti-histamine drops can cause pupil dilation as a side effect. CN 3 palsy, which is the dysfunction of the third cranial nerve, can result in a blown pupil as it controls the muscles responsible for pupil constriction. However, there is no direct link between orbital cellulitis or anti-hypertensive medications and blown pupil, so they are not considered as possible causes.

Submit
60. What are keratitic percipitates due to?

Explanation

Keratic precipitates are tiny deposits that form on the cornea of the eye. They are typically caused by inflammation in the eye, known as uveitis. Iritis specifically refers to inflammation of the iris, which is a part of the uvea. Therefore, iritis is a likely cause of keratic precipitates. Pannus refers to abnormal tissue growth on the cornea, and HZK stands for herpes zoster keratitis, which is a viral infection of the cornea. While these conditions can also cause inflammation in the eye, they are not commonly associated with the formation of keratic precipitates.

Submit
61. Indicate the situations where it is ESSENTIAL to culture a pt's red eye.

Explanation

In the given options, it is essential to culture a patient's red eye in the following situations: health care worker, pediatric infections, central corneal ulcer, ulcers that are not improving with current treatment, and hyperpurulent lesions. Culturing the red eye in these situations can help identify the causative organisms and determine the appropriate course of treatment. This is particularly important for health care workers who may be at risk of exposure to infectious agents, as well as for pediatric patients who may have different pathogens causing their infections. Central corneal ulcers, ulcers that are not improving, and hyperpurulent lesions may indicate more severe or resistant infections that require specific antimicrobial therapy.
