Summary
Triplanar sclerotomies demonstrate high intraoperative wound closure rates, with 93.9% of unsutured wounds sealing effectively. Complex surgeries may increase leakage risk, necessitating multiple assessment methods for sclerotomy integrity.
Area of Science:
- Ophthalmology
- Surgical Innovation
- Wound Healing
Background:
- Triplanar sclerotomies are a surgical technique used in ophthalmic procedures.
- Assessing intraoperative wound integrity is crucial for preventing complications.
Purpose of the Study:
- To evaluate the intraoperative integrity of triplanar sclerotomies.
- To determine the rate of wound closure and identify factors influencing leakage.
Main Methods:
- A prospective study of 180 triplanar sclerotomies in 60 eyes.
- Standardized technique using 23-gauge trocar, followed by air-fluid exchange.
- Wound integrity tested for vitreous, gas, and fluid permeability using cellulose sponge, gas escape observation, and Seidel method.
Main Results:
- 93.9% (169/180) of unsutured triplanar wounds demonstrated closure to vitreous, gas, and fluid.
- 11 sclerotomies showed leakage, with complex retinal detachment repairs having higher suture requirements.
- Transient hypotony occurred in one patient.
Conclusions:
- High rates of unsutured wound closure are achievable with triplanar sclerotomies.
- No single leakage assessment method is universally most sensitive; multiple methods are recommended.
- Complex cases with increased surgical manipulation correlate with higher leakage rates.
