Study Notes
Facial Observation in Ocular Disease
- Examine patient's face for symmetry, complexion, rashes, and lesions.
- Conditions to note include skin cancers, neurological disorders, rosacea, and eczema.
- Facial symmetry assessment includes checking eyebrows, eyelids, and overall facial appearance.
Periorbital Edema
- Defined as swelling of soft tissue around the eye, appearing "puffy."
- Causes can be systemic (kidney, hypothyroidism) or localized (allergies, infections).
- Systemic causes often lead to significant conditions requiring medical attention.
Pitting Edema
- Characterized by depressions left after applying pressure to swollen areas.
- Nephrotic Syndrome is a major systemic cause, linked to kidney disease; swelling appears around the eyes upon waking and may progress to ankles later in the day.
Myxedema and Hypothyroidism
- Florid Myxedema results from severe hypothyroidism, causing skin swelling and thickening without pitting.
- Symptoms include dull skin, puffy facial appearance, and dry, coarse hair.
Facial Features in Parkinson’s Disease
- Notable for a mask-like face and decreased blink rate, contributing to dry eye symptoms.
- Patients often exhibit a classic stare, with a forward flexed neck and upper body.
Neurological Impacts on Facial Symmetry
- Differentiate between lower and upper motor neuron defects by observing forehead wrinkles.
- Lower motor neuron issues, such as Bell’s palsy, cause paralysis affecting both upper and lower facial structures.
Bell’s Palsy
- Acute unilateral facial paralysis due to facial nerve inflammation, commonly viral (e.g., herpes).
- Limited ability to blink, asymmetric smile, and forehead wrinkles present only on one side.
- Good prognosis with a 90% recovery rate; up to 20% may experience residual weakness.
Upper Motor Neuron Defects
- Central lesions (CNS-related) lead to lower face weakness, while brow lifting and forehead wrinkling remain intact.
- Associated with conditions like multiple sclerosis and strokes.
Facial Complexion and Skin Conditions
- Inspect skin for rashes, blemishes, and lesions, and inquire about dermatological history.
- Skin conditions generally categorized into infectious, metabolic, contact dermatitis, and neoplasms.
Bacterial Infections
-
Impetigo: Common in preschoolers and young adults, caused by Staphylococcus aureus and Streptococcus pyogenes, characterized by vesicles and "honey-colored" crust.
-
Treatment involves penicillinase-resistant oral antibiotics; topical treatment is ineffective.
-
Erysipelas: A skin infection primarily affecting older adults and diabetics, marked by tender, red, warm, and swollen patches with fever.
-
Most frequently affects the face and lower extremities, indicating significant health risks.
