CL red eye causes

Question 1

solution hypersensitivity

Answer 1

gradual onset of conjunctival injection tat commonly begins after months of use of the solution. Patients may have minimal or no symptoms or may complain of burning after CL insertion. they will present with conjunctival hyperemia and diffuse, faint corneal subepi infiltrates.
-no staining

Question 2

how to treat solution hypersensitivity

Answer 2

switch to diff solution
consider dailies
temporarily DC CL wear if SEIs present and use topical steroid (after confirming not infectious in nature)

Question 3

SLACH

Answer 3

Soft lens associated corneal hypoxia

• neo
• tx-increased Dk lens and decreased wear time

Question 4

GPC

Answer 4

• FB sensation
• increased deposits on lenses
• decreased tolerance of CL
• friction causes it

non-infectious, inflammatory disorder associated with mechanical trauma and an immune response to CL deposits or environmental factors . may also be caused by exposed sutures, filtering blebs, scleral buckles, and ocular prosthetics

Question 5

CLARE

Answer 5

• severe injection
• SEIs more peripheral
• Tx=Abx/steroids drop

Question 6

infectious ulcer

Answer 6

• acute, pain
• photophobia
• 1:1 staining

Question 7

SPK from CL

Answer 7

diffuse

Question 8

tight CL

Answer 8

circumlimbal injection

decrease wear time

Question 9

SEI’s due to CLs

Answer 9

1. solution hypersensitivity

2. CLARE(acute)

Question 10

SEIs without CLs

Answer 10

EKC

-3 weeks, no longer active

Question 11

monovision

Answer 11

distance eye is the dominant eye

Question 12

simultaneous multifocal lenses

Answer 12

concentric rings of distance and near powers

Question 13

alternating design

Answer 13

translating
-the eye looks through the distance portion of the lens to view a distance object, and then looks down so the CLs shifts up and the patient is looking into the near portion of the lens for near tasks. these designs are stabilized with prism ballast or truncation of the lens

Question 14

simultaneous multifocal design

Answer 14

the CL has concentric rings of distance and near power, with the central portion most often used for reading. the patients pupil must be large enough so that half of the field os corrected for distance and the other half for near in each eye

Question 15

who does best in mono vision

Answer 15

early and emerging presbyopes

must have relatively equal BCVAs between the eyes
