“…Once adhesion between the retina and retinal pigment epithelium (RPE) has been established, the barrier is no longer needed. Theoretically, retina-RPE adhesion occurs within 24 hours in situations without subretinal fluid (SRF) [11]. However, remnant SRF around tears can disturb the adhesion, in which cases, the use of tamponade should be extended until the SRF is absorbed.…”

Purpose To investigate outcomes of vitrectomy for rhegmatogenous retinal detachment (RRD) using air exclusively as the gas tamponade. Methods This retrospective, interventional, consecutive case series involved reviewing medical records of patients that underwent vitrectomy and gas tamponade for RRD between January 2013 and December 2015. Patients whose eyes were treated exclusively with air tamponade since July 2014 were assigned to the air group, while those treated with heterogeneous gas agents before June 2014 were assigned to the control group. The primary outcome was the primary reattachment rate. Best-corrected visual acuity (BCVA) and duration to detect redetachments were assigned as the secondary outcomes. Results The air group and the control group included 71 and 72 eyes, respectively. The primary reattachment rate was 94.4% in the air group and there was no significant difference with 94.4% in the control group (p = 0.951). BCVA was significantly better in the air group at 1 month (p = 0.021) but not at 3 months postoperatively (p = 0.561). Redetachments were recognized earlier in the air group (9.3 ± 0.5 days) compared with those in the control group (21.3 ± 7.4 days) (p = 0.041). Conclusions In cases of simple RRD with sufficient removal of subretinal fluid, air could be considered for use as gas tamponade. This trial is registered with KCT0002358.

“…Further mechanical studies are needed to evaluate the functional nature of the retinopexy adhesions and the strength of adhesions between the sensory retina and choroid after diode laser retinopexy with intensities that try to spare the inner layers of the retina. Few studies on retinal adhesion to the underlying choroid are available with argon laser and they demonstrate a stronger retino‐coroidal adhesion in treated areas starting as early as 24 h after treatment, and being most effective after 1–2 weeks 27–29 . Rupture of Bruch's membrane might increase the chances of creating a stronger chorio‐retinal adhesion, but it should also be considered that longer wavelengths have deeper penetration and higher intensities.…”

The diode laser effectively produces lesions suitable for retinopexy in both the nontapetal, pigmented fundus and the tapetal fundus, although variably so in the latter region. Initial laser settings of 100-150 mW/200 mS for the pigmented fundus, and 150 mW/200-300 mS for the peripheral tapetal fundus are recommended, and the clinician should gradually increase time interval settings to achieve a grayish-white lesion in the nontapetum, and a bronze to slightly black lesion in the tapetal fundus. If possible, retinopexy should be applied to the peripheral tapetal area or tapetal/nontapetal junction.

“…It appears that DLT is effective in preventing the extension of SRF by providing rapid adhesion of the neurosensory retina to the retinal pigment epithelium (RPE). Histological studies by Folk and associates in enucleated monkey eyes and in an eye of a deceased diabetic patient showed that artifactual RD subsequent to tissue fixation and sectioning had occurred in all areas except those previously treated with laser [2]. These eyes had been removed only 20-24 h after photocoagulation.…”
