The effectiveness of subtotal vitrectomy with retinotomy in surgical treatment of severe forms of proliferative diabetic retinopathy with retinal detachment

The purpose of the study is to increase the efficacy of surgical treatment of severe stages of proliferative diabetic retinopathy in combination with circular retinotomy. Material and Methods. The operations performed in 2016-2018 on patients with proliferative diabetic retinopathy in combination with traction retinal detachment (17 eyes). The patients' age ranged from 24 to 69 years. Tractional retinal detachment was diagnosed alongside with PDR3-4 in all eyes. In 10 (58.8%) previously operated eyes we diagnosed the relapse of retinal detachment. In 14 eyes (82.3%), vitrectomy was performed in combination with phacoemulsification, 3 eyes (17.6%) were already pseudophakic. Results. We obtained complete anatomical attachment of the retina in all 17 cases (100%). All patients we kept on 5700 cSt silicone tamponade. Circular retinotomy was performed on 10 (58.8%) eyes with a relapse. The period of keeping silicone oil 5700 cSt in the vitreous cavity after a circular retinotomy varied (from 1 to 3 years), emulsification of silicone oil occurred in none of the cases. Secondary glaucoma developed in 3 eyes. Conclusion. Circular retinotomy in combination with prolonged tamponade of the vitreous cavity with silicone oil provides stable anatomical effect.
