Overview
Surgery is not the first-line treatment option for patients with acute retinal necrosis; it is primarily indicated when there is a substantial risk of complications, including retinal detachment and tissue atrophy.
Surgery
Surgery is not the first-line treatment option for patients with acute retinal necrosis; it is primarily indicated when there is a substantial risk of complications, including retinal detachment and tissue atrophy.[1]
Vitrectomy
- Vitrectomy may be indicated both before and after occurrence of retinal detachment to improve visual prognosis.[2]
- Prophylactic vitrectomy can be effective in removing inflammation factors, preventing retinal detachment by removing or preventing the spread of pre-existing lesions and necrotic tissue.[3]
- Remedial vitrectomy in patients experiencing retinal detachment can lead to improved visual prognosis by retinal reattachment.[4]
- The success of vitrectomy in improving outcomes is dependent on the time between the onset of acute retinal necrosis and the time at which the procedure is performed.[2]
- Increased extent of necrosis and larger size, as well as posterior located, lesions was associated with worse visual prognosis despite prophylactic or remedial vitrectomy.
- Prophylactic vitrectomy is often encouraged to maximize efficacy, performed in the early stages of ARN.
Prophylactic Laser Retinopexy
- Prophylactic laser retinopexy may be indicated to prevent retinal detachment by photocoagulation, creating posterior chorioretinal adhesions.[5]
- The procedure is contraindicated if there is vitreous inflammation or obstructed view and access to the posterior pole.
- Due to reported occurrences of retinal detachment from prophylactic laser photocoagulation, more research is necessary to determine the ideal indications for the procedure.[5]
- If performed on patients with excessive inflammation and vitreous opacity, there is evidence of photocoagulation worsening prognosis of acute retinal necrosis, leading to retinal detachment and blindness.[3]
