Summary
Initial experiences with the 25-gauge transconjunctival sutureless vitrectomy (TSV) system revealed surgical challenges and postoperative issues like hypotony and retinal detachment, yet it remains a convenient and safe option for vitreoretinal procedures.
Area of Science:
- Ophthalmology
- Surgical Innovation
Background:
- The 25-gauge transconjunctival sutureless vitrectomy (TSV) system represents an advancement in minimally invasive vitreoretinal surgery.
- Evaluating initial clinical experiences is crucial for understanding its safety and efficacy.
Purpose of the Study:
- To document the initial intraoperative and postoperative outcomes using the 25-gauge TSV system.
- To identify and analyze challenges associated with this novel surgical technique.
Main Methods:
- Retrospective review of medical records and surgical videos.
- Analysis of 50 consecutive cases performed by a single surgeon utilizing the TSV system.
Main Results:
- Intraoperative difficulties included microcannula insertion issues, instability, infusion tip disconnection, and lens damage, necessitating conversion to conventional vitrectomy in some cases.
- Postoperative complications observed were hypotony (8 cases), elevated intraocular pressure (6 cases), and retinal detachment (3 cases).
Conclusions:
- Despite identified intraoperative and postoperative problems, the 25-gauge TSV system demonstrates convenience and safety for a range of vitreoretinal surgical procedures.
- Further experience and potential modifications may mitigate the encountered challenges, enhancing the utility of TSV.

01:25Glaucoma: Overview
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
01:28Angle Closure Glaucoma: Treatment
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.
