In pharmacy, TTT can refer to Transpupillary Thermotherapy.
While the abbreviation TTT may have other meanings in different contexts, within the realm of pharmacy, particularly when discussing ocular treatments, it commonly stands for Transpupillary Thermotherapy. This therapy is a specific treatment modality that utilizes heat to address certain eye conditions.
Transpupillary Thermotherapy (TTT) Explained
TTT is a type of laser treatment that uses a low-energy diode laser to heat targeted tissues in the eye. The heat induces therapeutic effects without causing immediate tissue destruction, unlike other laser treatments.
Applications of TTT
- Intraocular Tumors: TTT was initially introduced as a treatment for intraocular tumors.
- Choroidal Neovascularization (CNV): While previously used more frequently, TTT is now rarely employed as a primary treatment option for choroidal neovascularization.
How TTT Works
TTT delivers a specific wavelength of laser light to the targeted tissue. The light energy is absorbed by the tissue, causing it to heat up. This controlled heating can:
- Reduce the size of tumors.
- Damage abnormal blood vessels associated with CNV.
Limitations and Alternatives
Due to the advent of more effective treatments, like anti-VEGF injections, TTT is less commonly used for conditions like CNV.
