Social History — Red Eye with Discharge

• Sick contacts with "pink eye" at home, school, work, or daycare - viral conjunctivitis is highly contagious via direct contact/fomites and often follows a household or classroom cluster
• Recent upper respiratory infection or contact with someone who had a cold/flu - viral conjunctivitis frequently accompanies a URI (correctional nursing red-eye assessment guide)
• Swimming pool use - chlorinated water irritation or adenoviral "pharyngoconjunctival fever" outbreaks
• Sharing towels, pillowcases, cosmetics, or eye makeup applicators - bacterial/viral transmission route; eye cosmetics can also cause allergic/irritant conjunctivitis

• Extended wear, poor lens hygiene, wearing lenses while swimming/sleeping, expired solution - major risk factor for bacterial keratitis/conjunctivitis (including Pseudomonas), which can mimic simple conjunctivitis but is a red-flag needing ophthalmology referral

• Welding, tanning, or high-altitude/snow exposure without eye protection - UV keratitis ("snow blindness"), which classically presents with red eye and NO discharge, an important negative finding
• Chemical, dust, or fume exposure at work - irritant/toxic conjunctivitis
• Outdoor/agricultural work and known allergen exposure (pollen, pet dander, dust mites) - seasonal or perennial allergic conjunctivitis, usually bilateral with itching and stringy discharge

• Unprotected intercourse or new/multiple partners - gonococcal or chlamydial conjunctivitis (hyperacute, copious purulent discharge for gonococcal; more indolent for chlamydial/inclusion conjunctivitis) - important to ask about even though patients may not volunteer this
• In neonates, maternal history of untreated STIs is relevant for ophthalmia neonatorum

• Crowding, limited access to clean water, or residence/travel in trachoma-endemic regions (parts of Africa, Middle East, Asia) - chronic follicular conjunctivitis/trachoma risk
• Smoking or secondhand smoke exposure - chronic irritant conjunctivitis

• Caregiver support for administering eye drops (pediatric, elderly, or visually impaired patients)
• Occupation or school/work policies requiring time off during contagious periods (most schools/daycares exclude children with bacterial conjunctivitis until 24 hours of antibiotic treatment)
• Health literacy and access to follow-up care, which affects whether red-flag symptoms (pain, photophobia, vision loss, no discharge with pain) will prompt timely re-evaluation

Why this matters in the map

Chief Complaint / HPI

Leading Diagnosis: Primary Open-Angle Glaucoma

Key Differentials to Rule Out

• Chronic angle-closure or secondary glaucoma (steroid-induced, pigmentary, neovascular, post-traumatic) - ask about chronic topical/oral steroid use, trauma, diabetes
• Chiasmal compression (pituitary adenoma, meningioma, craniopharyngioma) - produces bitemporal peripheral field loss that can also be described as "not seeing things to the side"; needs formal visual field testing to distinguish the pattern (arcuate/nasal step defect in glaucoma vs. bitemporal hemianopia in chiasmal disease)
• Retinitis pigmentosa - usually presents earlier with night blindness and a family history
• Chronic papilledema/compressive optic neuropathy

Risk Factors / PMH

• Age >50 (incidence rises sharply after 40-50) - Textbook of Family Medicine, p. 3126
• Diabetes mellitus - increased risk
• African American ethnicity - 4x more common, 8x more likely to cause blindness (not applicable if not stated, but worth asking)
• Family history of glaucoma (multifactorial/autosomal recessive inheritance patterns)
• Carotid vascular disease - reduces optic nerve perfusion
• Chronic corticosteroid use (topical eye drops or systemic) - can cause steroid-induced open-angle glaucoma
• Myopia (higher risk in some populations)

Social History

• Occupation and driving status - side/peripheral vision loss affects driving safety and job tasks (machinery, night driving)
• Access to routine eye care - tonometry screening is recommended at least every 3 years starting at age 35; delayed care explains a full year of untreated symptoms
• Steroid eye drop or nasal spray use (prescription or over-the-counter) - relevant exposure history
• Smoking and alcohol use - vascular risk factors affecting optic nerve perfusion
• Living situation/support - fall risk from peripheral field loss (bumping into objects on the side), especially if living alone
• Health insurance/financial access - glaucoma medications and follow-up require lifelong management, and cost is a common reason for non-adherence

Physical Exam & Diagnostics

• Visual acuity (usually preserved until late)
• Tonometry (Goldmann applanation, Tono-Pen, or Schiotz) to measure IOP - note about 10% of glaucoma occurs with normal IOP ("low-tension glaucoma")
• Fundoscopic exam for optic nerve cupping and thinning of the neuroretinal rim
• Formal automated visual field (perimetry) testing - defines the pattern (arcuate scotoma/nasal step = glaucoma; bitemporal = chiasmal lesion)
• Gonioscopy to confirm the angle is open
• If neuro cause suspected: MRI brain/orbits to rule out chiasmal mass

Nursing Diagnoses

• Risk for injury/falls related to peripheral vision loss
• Disturbed sensory perception (visual)
• Deficient knowledge related to disease process, chronic medication regimen, and irreversibility of vision already lost
• Anxiety related to threat of further vision loss/blindness

Interventions & Patient Education

• Emphasize that IOP-lowering treatment (topical medications first-line, laser trabeculoplasty, or trabeculectomy for uncontrolled cases) prevents further damage but cannot reverse vision already lost - early detection is critical (Textbook of Family Medicine, Key Treatment, p. 3158-3164, Strength of Recommendation A/C)
• Teach proper eye drop administration technique and adherence importance (lifelong therapy)
• Home safety modifications for peripheral field loss (clear walkways, lighting)
• Driving safety counseling
• Schedule regular ophthalmology follow-up with visual field and IOP monitoring
• Screen and refer first-degree relatives given genetic component

History of Present Illness (OPQRST)

• "When did you first notice trouble seeing things off to the side? Was it sudden or did it creep up gradually?"
• "Is it in one eye, both eyes, or do you notice it more on one side?"
• "Have you noticed yourself bumping into furniture, door frames, or people approaching from the side?"
• "Has it gotten worse over the past year, or has it stayed about the same?"
• "Do you have any eye pain, redness, headache, or nausea?" (helps rule out acute angle-closure glaucoma, which presents very differently - acute pain, red eye, halos, nausea)
• "Any blurring of your central vision, or is it mainly the sides that are affected?"
• "Do you see halos around lights at night?"
• "Have you had any recent injury or blow to the eye or head?"

Past Ocular History

• "Have you ever been told you have glaucoma, ocular hypertension, or high eye pressure?"
• "Do you wear glasses or contacts? Are you nearsighted (myopic) or farsighted?"
• "Have you had any eye surgery, laser treatment, or trauma in the past?"
• "Have you ever had eye inflammation, like uveitis or iritis?"
• "When was your last eye exam, and did they check your eye pressure?"

Medication History

• "Do you use any steroid eye drops, inhalers, nasal sprays, or oral steroids, now or in the past?" - chronic steroid use can precipitate glaucoma
• "Are you on any medications for allergies, bladder problems, or motion sickness?" (anticholinergics/sympathomimetics can precipitate angle-closure)
• "Do you take blood thinners or medications for blood pressure or diabetes?"

Past Medical History

• "Do you have diabetes or high blood pressure?"
• "Any history of stroke, TIA, or narrowing of the arteries in your neck (carotid disease)?"
• "Any history of migraines or poor circulation?"

Family History

• "Does anyone in your family have glaucoma or a history of vision loss or blindness?"
• "Any family history of pituitary tumors or neurological conditions?" (helps screen out chiasmal compression as a differential)

Social History

• "What kind of work do you do? Does your job involve driving or operating machinery?"
• "Do you smoke or drink alcohol?"
• "Have you noticed any difficulty driving, especially checking blind spots or side mirrors?"
• "Do you live alone, and has the vision change affected your daily activities or caused any falls or near-falls?"
• "Do you have regular access to an eye doctor, and what has kept you from being seen sooner for this year-long symptom?"

Associated/Red-Flag Symptoms (to screen out other diagnoses)

• "Any weakness, numbness, or trouble with balance?" (screens for stroke/neurologic causes)
• "Any headaches, especially worse in the morning, or hormonal changes like changes in libido, unexplained weight change, or new lactation/breast changes?" (screens for pituitary adenoma causing bitemporal hemianopia)
• "Any night blindness or trouble seeing in dim light that started earlier in life?" (screens for retinitis pigmentosa)
• "Any double vision or eye movement problems?"

Concept Map: 55-Year-Old Female, Gradual Blurring of Vision x 3 Months

Chief Complaint / HPI

Leading Differentials

• Cataract - most common cause of gradual, painless vision blurring in this age group. Lens opacification begins centrally (nuclear sclerosis) and progressively degrades vision, often with worse night vision and glare; can also cause acquired myopia ("second sight") from increased lens density (Goldman-Cecil Medicine, p. 590-592)
• Diabetic retinopathy/maculopathy - if diabetic, blurring is often the first symptom of macular edema; retinopathy takes years to develop but is a leading cause of blindness (Harrison's, p. 710)
• Uncorrected/changing refractive error - lens changes with age can shift refraction even without a mature cataract
• Age-related macular degeneration (early/dry form) - gradual, painless, bilateral central vision loss from drusen accumulation under the retinal pigment epithelium; slightly early for typical onset but possible (Harrison's, p. 691)
• Hypertensive retinopathy - if longstanding uncontrolled hypertension
• Dry eye disease - common in perimenopausal/postmenopausal women, causes fluctuating blur
• Medication-induced - chronic corticosteroid use accelerates cataract formation
• Thyroid eye disease - less common but consider if other systemic symptoms present

Risk Factors / PMH

• Diabetes mellitus (check duration and glycemic control)
• Hypertension
• Postmenopausal status/hormonal changes (dry eye risk)
• Chronic steroid use (topical, inhaled, or systemic)
• Family history of cataract, AMD, or glaucoma
• Prior eye trauma or surgery
• UV light exposure over lifetime (outdoor occupation)

Social History

• Occupation - visually demanding work (reading, driving, computer use) affected by blurring
• Smoking - strongly associated with cataract progression and AMD
• Alcohol use
• Diet - antioxidant intake (vitamins C/E, zinc, beta-carotene) may slow dry AMD progression (Harrison's, p. 691)
• Sun/UV exposure and use of protective eyewear
• Access to routine eye and diabetic screening exams
• Driving status and safety given visual symptoms
• Support system/living situation if vision impairment affects independence

Diagnostics

• Visual acuity testing (distance and near)
• Slit-lamp exam to visualize lens opacity
• Fundoscopic exam/dilated retinal exam for drusen, hemorrhages, exudates, macular edema
• Blood glucose/HbA1c if diabetes not already diagnosed or poorly controlled
• Blood pressure check
• OCT and fluorescein angiography if macular pathology suspected
• Tonometry/IOP to screen for concurrent glaucoma

Nursing Diagnoses

• Disturbed sensory perception (visual)
• Risk for injury/falls
• Anxiety related to vision loss
• Deficient knowledge regarding disease process and treatment options

Questions to Ask the Patient

• "When did you first notice your vision was blurry? Did it come on suddenly or gradually over the 3 months?"
• "Is it in one eye, both eyes, or worse in one than the other?"
• "Is the blur worse for distance, up close, or both?"
• "Do you notice more glare or halos around lights, especially at night, like when driving?"
• "Has the blurring been getting steadily worse, or does it come and go?"
• "Do you see any dark spots, missing areas, wavy or distorted lines, especially when looking at straight objects like doorframes?" (screens for AMD/macular pathology - metamorphopsia)
• "Any eye pain, redness, headache, or floaters/flashes of light?"
• "Any double vision?"

• "Do you wear glasses or contacts? When was your prescription last changed?"
• "Have you ever been told you have cataracts, macular degeneration, or diabetic eye disease?"
• "When was your last comprehensive eye exam with dilation?"
• "Any history of eye injury, surgery, or inflammation?"

• "Do you have diabetes? If so, how long, and how well controlled has your blood sugar been?"
• "Do you have high blood pressure or high cholesterol?"
• "Any thyroid problems?"
• "Are you currently going through or past menopause? Have you noticed dry, gritty, or irritated eyes?"

• "Are you using any steroid medications - eye drops, inhalers, or pills - now or in the past?"
• "Are you on any diabetes or blood pressure medications, and do you take them regularly?"

• "Does anyone in your family have cataracts, macular degeneration, glaucoma, or diabetes?"

• "Do you smoke or have you smoked in the past?" (major risk factor for both cataract and AMD)
• "What's your diet like - do you eat foods rich in leafy greens, fruits, or take any vitamin supplements?"
• "What kind of work do you do, and has the blurring affected your ability to do it?"
• "Do you drive? Have you had any near-misses or difficulty driving, especially at night?"
• "How much time do you spend outdoors, and do you wear sunglasses or UV protection?"
• "Do you live alone? Has this affected your daily activities or increased your risk of falls?"
• "Do you have regular access to eye care, and what prompted you to seek care now after 3 months?"

• "Any unexplained weight loss, fatigue, or increased thirst/urination?" (undiagnosed diabetes)
• "Any joint pain, dry mouth, or dry eyes together?" (Sjögren syndrome)
• "Any headaches or jaw pain when chewing?" (rule out giant cell arteritis if any visual field cut - less likely with gradual bilateral blur but worth a quick screen in this age group)
