Choriovitreal and Subretinal Proliferations: Complications of Photocoagulation

Photocoagulation of diabetic macular oedema; complications and visual outcome

“…A tear of the pigment epithelium by the use of small 50 mm laser spot together with a power setting greater than 300-400 mW has been discussed as a cause of this complication (Varley et al 1988;Benson et al 1979). In our study however, all 50 mm laser burns were given with a power set less than 200 mW.…”

An Atypical Case of Optic Disk Pseudo-Duplication With Proliferative Diabetic Retinopathy

“…This is also highly unusual, because diabetic neovascularization arises from the inner retinal vessels, not the choroid, 12 although choroidovitreal neovascularization can complicate overly-intense direct treatment of diabetic neovascularization. 13 Finally, if this lesion had been a true…”

Comparative effects of argon green and krypton red laser photocoagulation for patients with diabetic exudative maculopathy.

“…Using repeated small size short duration and intense burns to achieve ablation of microaneurysms is probably unnecessary, and should be avoided to minimise the risk of iatrogenic complications, such as choroidal neovascularisation, submacular fibrosis, and choriovitreal proliferation.
