Individualized treat and extend TREX-DME trial for DME resulted in significantly fewer injections and yielded visual and anatomic gains comparable to monthly dosing at 2 years.
Decreasing the treatment burden while providing clinically significant visual and anatomic improvements is of paramount importance.

Most patients of VMT gained significant functional and anatomical improvements after vitrectomy. Group 1 optical coherence tomography pattern, shorter symptom duration, and younger age are significant predictive factors of better visual outcome.

There are no approved drug treatments for autosomal-dominant retinitis pigmentosa.
A study of oral Valproic acid (VPA) does not support the use of VPA in the treatment of autosomal-dominant retinitis pigmentosa.
The lessons learned from a trial of Valproic acid are:
- Rigorous evaluation of drug treatment for retinitis pigmentosa is necessary.
- FDA-approved drugs for other uses can have major adverse effects.
- Patients vary greatly in their rates of progression of retinitis pigmentosa with identical gene mutations.
