About this study
In this study, regressed proliferative diabetic retinopathy, very severe, severe and moderate non-prolifrative diabetic retinopathy patients who were going to have a cataract surgery, underwent a complete eye examination, OCT, FAG and color photography 2 weeks prior to their operation. All patients divided in two: 1) control group (Phyco,PCIOL), 2) triamcinolone treatment group (Phaco with PCIOL+IVT). One month after surgery a complete eye examination will be done especially; IOP and endophthalmitis. A 6 month follow-up will be done for these two groups and diabetic retinopathy progression will be checked.

All patients divided in two: 1) control group (Phyco,PCIOL), 2) triamcinolone treatment group (Phaco with PCIOL+IVT). One month after surgery a complete eye examination will be done especially; IOP and endophthalmitis.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Triamcinolone in people with Diabetic Retinopathy, run by Shahid Beheshti University of Medical Sciences at 3 sites in Iran.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 24 Feb 2009. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 3 sites in Iran. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Siamak Moradian, MD (00982122592200, Moradian33195@yahoo.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Macula diameter (time frame: 6th week, 3, 6 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Feb 2009; AzTrials last refreshed its copy on 8 Nov 2026.
