“…The only neovascular glaucoma was reported after a laser anastomosis by Browning and Roberg [4], and it was complicated by recurrent vitreous hemorrhage. In our case, we did not observe any vitreous hemorrhage.…”

Purpose: To report the complications and long-term results of laser-induced chorioretinal venous anastomosis in vein occlusions. Patients and Methods: Eight consecutive eyes, 3 with central retinal vein (CRVO) and 5 with branch retinal vein occlusion (BRVO), were observed for up to 5 years after attempted laser-induced chorioretinal venous anastomosis. Results: Successful chorioretinal venous anastomoses were created in 2 (25%) eyes. Patients had severe complications, including vitreous hemorrhage, choroidal neovascular membrane, choriovitreal neovascularization, rubeosis iridis and neovascular glaucoma. Conclusion: The utilization of a chorioretinal venous anastomosis by laser with proposed laser settings as a therapeutic modality should be further analyzed, and a careful long-term follow-up must be done to avoid vision-threatening complications.

“…This technique offers a way of bypassing the site of obstruction to venous outflow. Unfortunately, further studies with some discouraging results with serious treatment-related complications caused physicians to question this technique’s reliability and validity [3,4,5,6]. We now report our long-term results in 8 consecutive cases.…”

“…The success rate of anastomosis formation in group 2 was higher. Most of the doctors in the literature used a very high-intensity argon laser alone, with power levels ranging from 0.6 to 4 W. [1][2][3][4][5][6] Two lasers were used in some eyes to create an anastomosis (argon and YAG), 1 but the author did not compare the success rate of anastomosis formation of this group of patients with that of the other patients. When combined lasers were used as in our study, less argon laser intensity was necessary to induce anastomosis formation.…”

“…1 Patients with 5-disc diameters or less of capillary nonperfusion were included in our study, whereas in most other studies, patients with 10-disc diameters or less of capillary nonperfusion were included. [1][2][3][4][5][6] This may contribute to the decreased occurrence of neovascular complications in our study. Second, distal vein occlusion at the treatment site occurred much less frequently in our study as described above.…”

“…The most serious complications associated with the treatment were choroidovitreal neovascularization that may lead to vitreous haemorrhage and traction retinal detachment. [1][2][3][4][5][6] We describe the treatment results using combined lasers with different wavelengths to induce CRVA in 85 eyes of 85 consecutive patients with nonischaemic central retinal vein occlusion (CRVO).…”

Aim To evaluate the effectiveness of combined lasers with different wavelengths in creating chorioretinal venous anastomosis (CRVA) in nonischaemic central retinal vein occlusion (CRVO). Methods In this retrospective, noncomparative, consecutive case series, records of all patients with a diagnosis of nonischaemic CRVO who underwent combined laser treatment to induce CRVA and who were followed-up for 6 months or longer were reviewed. Results Records of 85 patients (85 eyes) were analysed. These patients were divided into two groups. In group 1 (24 cases, 24 eyes), combined lasers with two different wavelengths (argon blue-green laser combined with Nd-YAG laser were used. In group 2 (61 cases, 61 eyes), combined lasers with three different wavelengths (argon bluegreen laser combined with krypton red laser and Nd-YAG laser) were used. Functional anastomosis formed in 13 out of 24 eyes (54%) in group 1 and 47 out of 61 eyes (77%) in group 2. In patients with successful anastomosis, visual acuity improved for two or more lines in 49 out of 60 eyes (82%), with the remaining eyes undergoing no change. There were no serious complications. Conclusion The use of three laser wavelengths results in the creation of laser anastomosis and the success rate may be higher than when using two wavelengths alone.
