Tonometry
Gonia
sutures
Nasolacrimal massage
Ultrasound

4

What procedures does Benoxinate used in?

Tonometry
only available as fluorescein preparation
LEAST corneal compromise
BUT may increase corneal thickness

5

What procedures does Procaine used in?

Herpetic neuralgia (injection)

6

What procedures does Benzocaine used in?

OTC oral
Dental
cough

7

What procedures does Cocaine used in?

otaryln-gology

8

What are some characteristics of Proparacaine?

- Least sting compared to Tetracaine
- Refrigerate once open (discolors)
- Potential to transiently increase corneal thickness affecting goldman and pre lasik pachymetry
- Most commonly used in eye care

9

What are Some characteristics of Tetracaine?

- GREATER toxicity/penetration than proparacaine
- Moderate stinging/ burning within installation

10

What are characteristics of Benoxinate?

only available as fluorescein preparation
LEAST corneal compromise
BUT may increase corneal thickness

11

What are the AMIDE ANESTHETIC drugs?

Lidocaine
Etidocaine
Mepivicaine
Bupivicaine
Prilocaine
Ropivacaine

12

What are features of Lidocaine?

- Toxicity risk: seizures,
- Satruable metabolsim (zero kinetics)
- when used TOPICALLY it will not have any visible effect of the corneal epithelium

- Its good when injected for regional nerve block for large chalazions

- Local and regional Anesthetic
- Status eplepticus
- Ventricular arrthmia
- Forced cuctions

13

What are features of MEPIVICAINE

Has no preservatives
Local and regional anesthetic

14

what are features of BUPIVICAINE?

Local anesthetic and regional anesthetic
uses is obstetrics

15

what are features of ETIDOCAINE?

severe corneal ulcer

20

What are the adverse effects of cocaine on systemic?

exciement
convusions
rapid palpitations
Nausea
delirium

21

What are the adverse effects of cocaine on ocular?

Desquamation/debriding (can be used as andvantage in PRK),
MYDRIASIS,
LID RETRACTION (DUE TO MULLERS MUSCLE)

22

What is a adeverse effect of cocaine on general?

can lead to hypertension (incrased heart rate with vasocintrction)

23

what other drugs does cocaine interactions with that could lead to adverse effects?

TCADs (Tricyclic antidepressants
MAO inhibitors
Guanthidine
Epinephrine
Phenylephrine

24

what type of inhibitor is TCADs?

It is a newer selective serotonin reuptake inhibitor
however
it is much less selective for serotonin alone

25

What about MAO?

monoamine oxidase
a key enzyme invovledi n catecholamine metabolsim

26

 Guanathidine is a?

antihypertensive that competes with norepinephrine for presynaptic uptake to ultimately occupy sotrage vesicles and dampen norepehineprine

27

What is RESERPINE?

It is a antipsychotic, antihpertensive that blocks presynaptic monoamine uptake

28

Desquamation is common in?

50+ patients that has reduced blink rate
Reduced tear production
Increased evaporation
VA may decline 20/80 to 20/100
and healing may take up to 24 hours

29

corneal edema
Cojunctival hyperemia
Allergic cojunctivitis
Lacrimination

30

what should be avoided if there is a bforeign body injury?

aoid eye rubbing 20/30 min
