retinal hole photocoagulation

Retinal breaks without retinal detachment and retinal breaks that have been placed under pressure and without retinal fluid around the eyes can be closed by photocoagulation. Treatment of diseases: retinal tear retinal detachment Indication Retinal breaks without retinal detachment and retinal breaks that have been placed under pressure and without retinal fluid around the eyes can be closed by photocoagulation. Contraindications Older, combined with severe heart, liver, kidney and other diseases and difficult to tolerate surgery. Preoperative preparation No special preparation before surgery. The laser can be selected from argon laser, holmium laser, diode laser and yag frequency doubled laser. Three- or micro-retina mirrors can be used in photocoagulation, or in indirect ophthalmoscopy during surgery. Surgical procedure 1. Adjust the laser machine parameters, the spot size is selected from 300 to 500 m, and the exposure time is greater than 0.2 seconds. 2. Expose the hole under a three-sided or full retinal mirror. 3. The laser energy is weak to strong, which is subject to the appearance of white reaction. 4. The spot around the hole is a fusion reaction, generally 2 to 3 rows ("keep-off-technik"). complication eye pain.
