Explanation:
Given the specific eye injury and symptoms, a cerebrospinal fluid leak and a hyperdense area in the occipital lobe are less directly related to the described presentation of traumatic optic neuropathy. The more likely findings would involve structures closer to the orbit and optic nerve.
Explanation:
Optometrists have an ethical obligation to prioritize the well-being of their patients. This includes using confidential information obtained during examinations solely for the benefit of the patient's health and safety. Therefore, the optometrist should use the information to provide appropriate recommendations and interventions to ensure the patient's visual health and safety, which may include discussing concerns about driving if necessary.
Explanation:
Intravitreal bevacizumab is an anti-VEGF (vascular endothelial growth factor) treatment effective for managing choroidal neovascular membranes, which are associated with conditions like age-related macular degeneration. This treatment helps reduce hemorrhage and neovascularization, thus improving or stabilizing vision.

Explanation:
In the initial management of an acute anaphylactic reaction, it is crucial to administer systemic epinephrine, as it is the first-line treatment to counteract the severe allergic response. Additionally, calling 911 ensures that the patient receives prompt medical attention and further necessary treatment.
Explanation:
While ultraviolet (UV) radiation can have detrimental effects on the eyes, it is not typically emitted by computer displays. Screen reflections, window glare, and uncompensated astigmatism are more common factors contributing to visual fatigue and asthenopia when using computer displays. UV radiation is more commonly associated with outdoor exposure or exposure to sources such as sunlight and certain artificial light sources, rather than computer screens.
Explanation:
Penicillin V is the best oral medication for treating acute streptococcal infections, such as erysipelas. It is effective against Streptococcus bacteria, which is the cause of the condition. Tetracycline and doxycycline are not typically used in children due to potential side effects, and cyclosporine is an immunosuppressant, not an antibiotic.
Explanation:
Cromolyn 4% is the least effective in treating her condition. Cromolyn is a mast cell stabilizer used to prevent allergic reactions, but it is typically less effective for treating acute symptoms such as severe itching and redness compared to antihistamines like Chlorpheniramine or Olopatadine, which directly target histamine release and alleviate symptoms more quickly.
Explanation:
Long-term treatment with tetracycline can cause side effects such as skin photosensitivity, papilledema, and gastrointestinal distress. However, ototoxicity (damage to the ear leading to hearing loss) is not typically associated with tetracycline.
Explanation:
The presence of a relative afferent pupillary defect (RAPD) and light-perception vision in the affected eye, coupled with normal intraocular pressure and extraocular muscle motility, strongly suggests traumatic optic neuropathy. This condition can result from blunt trauma, such as an airbag injury, leading to damage to the optic nerve without visible fundus abnormalities.
Explanation:
The patient's symptoms of severe itching, redness, and conjunctival chemosis, especially following exposure to an outdoor environment (weeding the garden), are most consistent with allergic conjunctivitis. This condition is commonly triggered by environmental allergens such as pollen.
Explanation:
Ciprofloxacin is an effective antibiotic against Gram-negative organisms. Given that the Gram stain reveals predominantly polymorphonuclear leukocytes and Gram-negative organisms, ciprofloxacin would be the most appropriate choice for treating the infection.
