Summary
Trabectome surgery, an ab-interno trabeculectomy, significantly reduces intraocular pressure and improves vision in glaucoma patients. This glaucoma treatment demonstrates long-term safety and efficacy, with a low complication rate.
Area of Science:
- Ophthalmology
- Glaucoma Surgery
- Minimally Invasive Glaucoma Surgery (MIGS)
Background:
- Glaucoma management requires effective long-term strategies to control intraocular pressure (IOP).
- Ab-interno trabeculectomy using the Trabectome device offers a minimally invasive surgical option.
Purpose of the Study:
- To assess the long-term safety and efficacy of ab-interno trabeculectomy with Trabectome.
- Evaluate the impact on intraocular pressure, visual acuity, and medication use.
Main Methods:
- Retrospective analysis of 339 eyes undergoing Trabectome surgery.
- Collected data included IOP, best-corrected visual acuity (BCVA), visual fields, and complications.
Main Results:
- A statistically significant IOP reduction of ~23% (p < 0.01) was observed at an average follow-up of 18.35 months, sustained up to 8 years.
- 69% of eyes showed improved BCVA (p < 0.05), with a low complication rate of 5.86%.
- Success rates ranged from 80% to 100% at 100 months post-procedure.
Conclusions:
- Trabectome surgery is a safe and effective long-term treatment for various forms and severities of glaucoma.
- The procedure offers sustained IOP reduction and visual acuity improvement with minimal complications.

Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

Information is everywhere and its presentation—such as how and when items are presented—can impact our perceptions and decisions surrounding the info. This broad concept umbrellas framing effects—influences that occur due to the way information is framed in its appearance, whether it’s purely the order or the specific wording of a message. Let’s take a look at numerous ways in which two versions of something can objectively say the same thing, yet we respond in...

02:59Biological Effects of Radiation
17.7K
All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they...

16.0K
Directional terms are essential for describing the relative locations of different body structures. For instance, an anatomist might describe one band of tissue as "inferior to" another, or a physician might describe a tumor as "superficial to" a deeper body structure. These terms often use comparative terms in pairs to trace out the relative locations of one body part to another or descriptions of body tissues like the deeper ones from superficially present with reference to...
