What deficiency is damage or inflamm of goblet cells causes erythema multiformea
Mucin deficiency
Dec. in what is common w patients w blepharitis
Lipid deficiency
Defects in corneal epithelium that can impair tear film stability
Epitheliopathies
What conditions best for warm and cold compresses
Warm: Blepharitis and hordeolum
Cold: Conjunctivitis and dry eye
Pharmacotherapies like substituted cellulose ethers
Ointments
Art. tear inserts
substituted cellulose ethers: Polyvinyl polymers PVP
Ointments: petrolatum and carbomer
Art. tear inserts: hydroxypropylcellulose HPMC
Others: Pilocarpine, Acetylcysteine, Methylprednisone
Emollients: lanolin, min. oil, petrolatum
Hard lens: Hydrophobic Polymethyl methcrylate (PMMA) Life 5yr until lost daily wear time <12h low microbial contamination STRONG
Soft lenses: Hydrophilic Hydroxyethyl-methacrylate (HEMA) 1 day to 1 yr daily wear time >12h high microbial contamination FRAFILE *disposable opened daily, no reg. soln. required
Contact lens solutions:
Surfactants
Protein/ enzyme cleaners
Wetting and rewetting solutions
Surfactants- remove loose debris and protein cleaners, disinfect contaminants
Protein/ enzyme cleaners- contain papain, pancreatin, subtilism. Remove prot. deposits by natural brkdwn of debris
Wetting and rewetting solutions- cushioning, lubricant effect
DIs with contact lenses
OCP antihistamines hypnotics sedatives anticholinergics Isotretinoin and ASA
OCP alters tear comp. = dec. lubri
antihistamines hypnotics sedatives- dec. blink rate (hydration)
anticholinergics antihistamines TCAs- dec. tear volume
Isotretinoin- itch, dec. wear time in soft lens
ASA- ocular irritation, redness in soft lens
Drugs that cause discoloration of soft lens
Dopamine Nitrofurantoin Sulfasalazine Tetracyclin Phenazopyridine Phenolphthalein Rifampin Pyrantel pamoate
Mouth ulcers remedies:
Local anes, analgesics protectants and RX meds
Local anes: Benzo, Lidocaine
analgesics: aceta, NSAIDs, ASA
protectants: hydroxycellulose, base agents Zilactin and Oractane
RX meds: Corticosteroids, Fluocinomide, Clobetasol and Triamcinolone
Accumulation of puss in dental cavities and DOCs
Dental abscess.
Pen V, Amoxi or Eryth (base for adults and estolate for children)
