Ophthoquestions Flashcards
Phacomorphic glaucoma my present with
asymmetric anterior chamber depths with intumnescent cataract
Patients with PACG are typically
hyperopes with shallow AC
What type of agents should be avoided in inflammatory glaucomas?
miotic agents
Main conclusions of Collaborative Initial glaucoma treatment study?
- Early VA loss was greater in surgery group with eventual convergence with time.
- Patients with worse baseline fields were likely to progress if treated with trabeculectomy first.
- More local eye sx in surgery first. and increased cataract formation.
- Surgery reduces IOP more.
- Same results after 5 years
Ocular HTN treatment study result that treating decreases conversion from what to what?
from 9 to 4
Advanced Glaucoma Intervention study
Caucasians did better with initial trabeculectomy compared to initial laser trabeculoplasty
Early manifest glaucoma treatment trial
62% of untreated vs. 45% of treated patients showed progression in visual fields
Increased IOP in PCG may result in irreversible
increased corneal diameter
CNTGS study showed lowering IOP by 30% results in a decrease in field progression from
35 to 12%
Percent prevalence of POAG in ppl over 40
1.86%
Only selective beta 1 beta blocker
betaxolol
Normal tention glaucoma
Increased diac hemorrhages, more peripapillary atrophy, disc notching, more disc sloping, larger optic disc size, VF defects deeper and closer to fixation. Ocure more commonly in ppl of japanese-descent and in ppl with vasospastic disorders.
What two areas of vision are last to be affected by end-stage glaucoma
Central island and inferotemporal visual field
Risk factors for development of glaucoma
Increased age, Africal race, decreased CCT, positive family history
In sporadic cases of aniridia patients should have
abd. ultrasound to screen for Wilms tumor
