Opthalmic Infammatory and Dry Eye Conditions

Describe self-care measures for blepharitis and hordeolum/stye (inflammation of the eyelid conditions)

Blepharitis 

• Washing eyelids everyday with baby shampoo

• Washing hair and eyebrows with an antibacterial soap to reduce bacterial growth 

• Warm compass

  • Wet clean washcloth with warm water and wring it out before use

  • Close eyes and put washcloth on eye for 1 minute

  • Can rewet wash cloth and do this again at a few minutes at a time

  • Benefit: loosens flakes, calms itching.burning, keeping oil gland open and functioning right reducing dry eyes symptom

• Doctor:

  •  antibiotic pills or ointments 

  • Lubricating eye drops, steroid eye drops, and antibiotic eye drops 

Chalazia

• Warm compress: 

  • Soak a clean washcloth in hot water and hold it to your eyelid for 10–15 minutes at a time, 3–5 times a day. Keep the cloth warm by soaking it in hot water often. For a chalazion, this warm compress helps the clogged oil gland to open and drain. You can help the gland clear itself by gently massaging around the area with your clean finger.

• Antibiotics or Steroid Shots:

  • The PCP/ophthalmologist may prescribe an antibiotic for an infected stye. If the chalazion is very swollen, the ophthalmologist may give a steroid shot (cortisone) to reduce the swelling.

• Surgery to drain the area

  • If the stye or chalazion affects vision or does not go away, it may need to be drained. This surgery is usually done in the doctor’s office using local anesthesia.

• If a stye or chalazion keeps coming back time after time, an ophthalmologist may biopsy it. This is where a tiny piece of tissue is removed and studied. This helps the ophthalmologist check to see if there is a more serious eye problem.

Distinguish between the causes, defining features, and treatments for the three types of conjunctivitis

• Infection or inflammation of white part of eye or the tissue on top (conjunctiva)

Bacterial conjunctivitis

• Thick, mucus, sticky discharge that might have some yellow or green color

• In the morning, lid are going to be matted shut and stuck shut with material 

• Duration: 5-7 days, immune system is self-limiting (mostly clear on own)

• Presents only in one eye usually, but might spread to the other because it is contagious by touch 

• Treatment

  •  immune system is self-limiting (mostly clear on own)

  • Antibacterial eye drops; some OTCs but not strong enough

    • Prescription are strong tho - shorten by a few days 

Viral conjunctivitis

• Watery discharge and weepy eyes with small amount of mucus

  • Swelling 

• Last 7-14 days

• Virus can start in one eye and spread to other; spread acts similar to bacterial 

• Treatment

  • No antiviral meds that can help with this, so has to letting it clear on own

  • In some cases, in the doctor’s office there can be treatment done with Betadine which will kill active viruses on surface to quicken its course

  • Doctors may also prescribe steroids after the infection to bring down the inflammation on the cornea from some viral infections 

Allergic conjunctivitis

• A little weeping, not really any discharge; just reddening like the others

  • Red and itchy; bilateral 

• Seasonal allergies or animal allergies

• Treatment

  • Antihistamines eye drop (OTC and prescription)

  • Contact lenses with antihistamines (Acuvue)

Ophthalmic Antihistamines and Ophthalmologic antihistamines/ Mast cell stabilizer  -OTC

Non-prescription

• Agents:

  • Pheniramine maleate

  • Antazoline phosphate

• Effective alone, but most OTC products also include a decongestant

• Common combinations:

  • Pheniramine + naphazoline

  • Antazoline + naphazoline

• Belong to different antihistamine classes, but both:

  • Act as H₁-receptor antagonists

• Indications:

  • Rapid relief of symptoms from:

    • Seasonal conjunctivitis

    • Atopic conjunctivitis

• Combination therapy (antihistamine + decongestant):

  • More effective than either agent alone

• FDA classification:

  • Considered less than effective due to limited clinical efficacy data

RX-Ophthalmic Antihistamines and Ophthalmologic antihistamines/ Mast cell stabilizer 

• Mechanism of Action:

  • Strong H₁-receptor antagonist → prevents acute histamine-mediated symptoms

  • Stabilizes mast cells → inhibits degranulation and release of histamine and other inflammatory mediators

  • Inhibits eosinophils → reduces late-phase allergic response

• Advantages:

  • Relief within minutes

  • Effects last up to 12 hours with a single dose

  • No vasoconstrictor

  • No risk of vasoconstrictor overuse or rebound redness

Seek help

• Pain, discomfort, long duration

• If wear contact lenses- see doctor 

Dry Eye Disease (DED) ManagementNonpharmacologic Therapy (Lifestyle Modifications)

• Goal: Stabilize the tear film and decrease evaporation.

• Environmental Controls: Avoid dry, dusty, or windy places. Reposition workstations away from direct heating and air conditioning vents. Use humidifiers to add ambient moisture.

  • Eye protection 

• Behavioral Changes: Avoid prolonged viewing of computer screens (which lowers blink rate). Wear eye protection (sunglasses or goggles) in windy outdoor environments.

• Lid Hygiene: Utilize warm compresses and lid scrubs to improve lid function and provide anti-inflammatory benefits.

• Adjuncts: Consider dietary omega-3 or flaxseed oil to support lid health.

Dry Eye Disease (DED) Management

Pharmacologic Therapy: Ocular Lubricants

Artificial tears vary primarily by viscosity, which dictates their clinical role and side-effect profile.

• Low-Viscosity Drops:

  • Less contact time on the eye and higher susceptibility to tear dilution.

  • Used for mild cases of dry eye.

• High-Viscosity Drops & Gels:

  • Prolonged ocular contact time and greater resistance to tear dilution.

  • Used for moderate-to-severe dry eye.

  • Gels offer an advantage over ointments because they do not disturb vision as significantly and are better tolerated.

• Nonmedicated Ointments (e.g., Petrolatum):

  • Mainstay for minor ophthalmic disorders.

Reserved for severe cases or bedtime use due to their strong tendency to cause blurred vision

⚠ Clinical Pearl (Preservative-Free Formulations):

Formulations without preservatives are significantly less likely to irritate the ocular surface. However, because they lack antimicrobial protection, patients must be strictly counseled to discard nonpreserved products immediately after being opened.

Allergic Conjunctivitis & Ocular Decongestants

Nonprescription allergy drops frequently utilize decongestants (vasoconstrictors), antihistamines, or astringents.

Therapeutic Categories & Products

• Decongestant-Only Drops: Naphazoline, Tetrahydrozoline, Oxymetazoline, Phenylephrine.

• Antihistamine / Mast Cell Stabilizer: Ketotifen 0.025% (e.g., Zaditor, Alaway).

• Antihistamine / Decongestant Combos: Pheniramine maleate + Naphazoline HCl (e.g., Naphcon A, Opcon-A).

• Decongestant / Astringent Combos: Naphazoline + Zinc sulfate (e.g., Clear Eyes ACR). Zinc sulfate acts as an astringent to soothe surface irritation.

Critical Safety Warnings & Rationale

Risk Factor	Clinical Consequence & Mechanism	Patient Counseling / Action
Rebound Hyperemia (Medicamentosa)	Excessive or long-term use causes severe rebound redness/congestion. Can appear within days, or as quickly as 8 hours.	Limit use to a maximum of 72 hours (3 days). Naphazoline/tetrahydrozoline have a lower risk than oxymetazoline/phenylephrine.
Narrow-Angle Glaucoma	Decongestants can cause mild papillary dilation (mydriasis). In narrow angles, this can physically block fluid outflow and precipitate an acute angle-closure glaucoma crisis.	Strictly contraindicated. Patients with narrow anterior chamber angles must be counseled against using these products.
Systemic Disease Risks	Systemic absorption of alpha-agonists can trigger adverse cardiovascular and endocrine events.	Use with extreme caution in patients with systemic hypertension, arteriosclerosis, cardiovascular disease, diabetes, or hyperthyroidism.
Pregnancy	Potential for systemic vasoconstriction.	Pregnant women should use ocular decongestants sparingly, if at all.
Pediatric Toxicity	Accidental oral ingestion of these solutions can cause severe coronary emergencies and death.	Keep strictly out of reach of children. Monitor use closely if therapy is indicated for a child.
