  • shift to hyperopia ag e20-70ish
  • late shift towards myopia with cataract development
  • younger adutls 80% WTR older adults 80% ATR

Q

Lens changes

A
  • lens paradox: refers to the lens becoming more curved with aging which should result in age-related myopia from age 30-60s but doesnt, thought to be due to refractive index gradient change from centeral to peripheral lens
  • lens index decreases
  • lens power decreases
  • vitreous length unchanged
  • aberrations increase

Q

Seborrheic blepharitis

A

Goes along with the dermatitis
Dry flaky skin
-common in Parkinson’s disease

24
Q

Anteiror blepharitis almost always ____ related

A

Staph or demodex

25
Q

Eye movements in elderly

A

Upgaze pursuit range not as great
Saccades little change
Phoria largely unchanged
Vergence ranges decreases

26
Q

Hudson stahli line

A
  • iron deposit
  • lower 1/3 line of cornea
  • no clinical consequence
27
Q

Arcus

A
  • virtually everyone over 50, extremely common in US

- if under 50, patient should have lipid work up

28
Q

Crocodile shagreen

A
  • typical in the elderly
  • polygonal clouds in the midperiphery to peripheral cornea
  • due to loss of collagen cross links
  • no clinical problems
29
Q

Limbal girdle of Vogt

A
  • subepithelal in the 3 and 9 area
  • has a bubbly white appearance on high illumination
  • not significant
30
Q

Guttata

A
  • degeneration change on the endothelium
  • common in midperiphreal cornea
  • asymptomatic
  • specials reflection Cn help identify
31
Q

Fuchs dystrophy

A
  • excessive guttat central cornea
  • assocaited with corneal swelling
  • stromal and epithelial edema
32
Q

EBMD

A
  • map dot finger print
  • bilateral upper and lower third of cornea usually
  • very common caucasians
  • rarely symptomatic
33
Q

Fibrovascular placque

A
  • closed loop of neo associated with superficial fibrosis
  • usually inferior
  • assocaited with chronic dry eye
34
Q

Other corneal age findings

A
  • loss of sensitivity with aging-less sensitive to abrasions
  • loss of endothelial cells: typical is 1200-1500 cells/mm
  • below 1000, cornea decompensated and may have edema
  • at risk: dystrophy pts, glaucoma pts, uveitis pts
35
Q

Dry eye and age

A
  • ubiquitous in older people (1/3ish population)
  • common pathway is hyperosmoarity
  • asymptotic patients rarely take drops
36
Q

Conjunctiva and age

A
  • dishesence
  • dis-insertion of the conjunctiva, associate with dry eye syndromes in older adults
  • surgical repair an option
37
Q

Episcleritis in older

A

No good numbers on prevalence

38
Q

Senile scleral plaque

A

Grayish patch over the insertion of medial or lateral rectus, can have a yellow outline

39
Q

Miscellaneous conjunctival pigmentation

A

Primary acquired Melanosis
Silver nitrate
Complexion-associated Melanosis

40
Q

AC and age

A
  • becomes shallower and angles becomes narrower with cataracts and aging
  • trending a bit more towards cataract surgery rather than PI
  • many of cytokines in the AC decrease with age
  • zinc and TGF-B increase with cataracts
41
Q

TM and age

A
  • angle crowding with cataracts
  • filtration is less efficiency
  • IOP however does not increase statistically with normal aging
42
Q

Lens water vacuoles

A
  • throughout lens but common around posterior cortex, can be confused with PSC
  • rarely symptomatic
43
Q

Lens-cortical

A
  • very commn age related cataract
  • less likely to go to surgery
  • glare is most common complaint
44
Q

PCS

A
  • most visually disconcerting
  • occurs at a younger age
  • multicolored “splattered sand”
  • use retro
45
Q

Nuclear cataract

A
  • judge by opalescence
  • judge by colro
  • by far the most common reason for cataract surgery
46
Q

Grading cataracts

A

Use the LOCS III

47
Q

Cataract surgery

A 
Most common surgery in the US
1.8 million per year
 Its expensive to society
Oldest cataract surgery patient was 109
Generally, cost benefit is up to 95 in men and 96 in women-if pateitns are healthy/systemic conditions are stable, there is no age limit
48
Q

Bette quality of life and cataract

A

Great healthy of life gain

49
Q

One vs two eyes cataract surgery

A

61% greater increase in VF-14 over one eye

50
Q

MFIOLs

A

Be careful with patient selection. MFIOLs are good for most patients wanting independence from glasses, but avoid in

  • patients who suffer from night vision problems due to conditions other than cataracts
  • patients that have poor contrast sensitivity
  • patients who are overly critical/exacting
  • treat dry eye adequately before-15% of pateitns who were unsatisfied had dry eyes

MFIOLs today are much better designed than previously-most use a diffractive design that can give good distances intermediate, and near

51
Q

Spec indentence and cataract surgery

A
  • after 2011, showed between 75-100% spectacle independence

- generally patients who needed glasses neede them for near only

52
Q

Contrast sensitivity and cataract surgery

A
  • contrast sensitivity decreases significantly for pateitns wearing MFIOLs
  • the amount of focused light reaching the retina is decreases
53
Q

Asteroid hyalosis

A
  • usually unilateral
  • cholesterol deposit
  • may be only in periphery
  • shorten your viewing distance to see around
54
Q

Retina/optic nerve

A
  • FLR more likely to be absent
  • ILM reflections absent
  • arterial light reflex widens
  • AV ratio decreases
  • optic nerve changes little ophthalmoscopically
55
Q

Atherosclerosis risk in community

A

Higher risk of mini strokes (white matter lesions) if you have CWS, etc

If someon has both retinopathy and WML, then they are a lot more likely to get a clinical stroke (2000% more likely). Do MRIs to look for strokes

56
Q

MESA

A

Blood pressure nad aging both thin arteries
