Eye
A patient presents with inflammation and erythema along the margin of the eyelid. There is also crust and ulcerations around the eyelashes. What is their diagnosis?
Blepharitis
The ear consists of these three compartments.
External ear, Middle ear, and inner ear.
Primary, Secondary (to disease, trauma or drugs), and congenital (due to strucutral or functional anomalies developing prenatally)
These are the 2 classifications of symtpomatic dry eye.
Aqueous-deficient and evaporative.
These two populations are most prone to dry eye.
Asians and Women
The two phases of hearing
Conductive phase and sensorineural phase
The mean IOP
15.5 +/- 2.5 mmHg
The tear film is said to be composed of these 2 layers in the updated description.
Mucoaqueous layer, Lipid Layer
Hordeolum (stye)
These two tests are used during the physical assessment of the ear to test for hearing loss.
Weber test and Rinne test
Aqueous humour leaves the eye via the trabecular meshwork to schlemm's canal.
Conventional route
When evaluating patient history when assessing the ear, it is important to screen for these 4 components of family history.
Hearing loss (especially in childhood), head and neck cancers, genetic malformations, and perinatal viral infections.
Erythromycin 1-4 times daily x 1-2 weeks, decrease to QD for 4-8 weeks and then continue 1 month after symptoms subside. This is an appropriate sig for this nonsevere eye condition.
Blepharitis
The 6 common abnormalaties of the ear as outlined in Laurie Graham's lecture
Microtia, Anotia, Otitis media (with effusion and acute), otitis externa, malignant otitis externa, tinnitus.
The 5 purposes of the aqueous humour
provides nutrition, removes excretory products, transports neurotransmitters, stabilizes the ocular structure and contributes to regulation of homeostasis of ocular tissues.
Fluoroquinolones such as these 3 are well tolerated in the ear and treat a broad spectrum of bacterial infections.
Ciprofloxacin, Moxifloxacin, and Ofloxacin.
Besifloxacin, Gatifloxacin, Moxifloxacin and Tobramycin are ophthalmic antibiotics used to prevent this postoperative complication.
Endophthalmitis
7 predisposing factors for acute otitis externa
Too little/too much cerumen, moisture, trauma to the canal, chronic dermatologic conditions, hearing aids, narrow/hairy ear canals, age 7-12.
IOP is impacted by these 5 things.
Heartrate and blood pressure, coughing, neck compression, posture, circadian variation.
These 4 water based cerumenolytics can be beneficialm to soften the cerumen before irrigation.
Docusate sodium 10mg/ml, Hydrogen peroxide 3%, Sodium bicarbonate 10%, Water/saline.
