Hypothesis
Does the treatment of choroidal neovascular membranes with verteporphin photodynamic therapy or transpupillary thermotherapy influence the presence of heat shock protein 70?
Conclusion
Heat shock protein 70 is present in most choroidal neovascular membranes secondary to age-related macular degeneration, and treatment does not seem to affect its expression.
Supporting Evidence
- Of the 14 membranes analyzed, 11 were Hsp70 positive.
- In the no pre-treatment group, 6 out of 8 membranes were Hsp70 positive.
- All 4 membranes from the PDT group were positive for Hsp70.
- In the TTT group, 1 membrane was positive and 1 was negative for Hsp70.
Takeaway
The study looked at eye membranes from patients with a specific eye disease and found a protein that helps protect cells is mostly present, regardless of the treatment used.
Methodology
The study involved analyzing choroidal neovascular membranes removed from patients using light microscopy and histochemistry to detect the presence of Hsp70.
Limitations
The study had a small sample size and limited data on the effects of treatment timing on Hsp70 expression.
Participant Demographics
14 patients (7 female, 6 male) with an average age of approximately 73 years.
