Giant Retinal Tears

Retinal detachment due to giant retinal tears (GRTs) poses significant challenges in their management due to their large size, fast progression of retinal detachment, and technical difficulties in reattaching the retina. Whilst GRTs can be linked to inherited vitreoretinopathies or trauma, most cases are idiopathic. Preoperative considerations include assessing phakic status, posterior hyaloid detachment, differentiating GRT from retinal dialysis, and evaluating the extent and location of the GRT including foveal status. Management includes mainly pars plana vitrectomy, laser retinopexy, and vitreous tamponade. The use of perfluorocarbon liquid (PFCL) to unfold the GRT flap before laser is usually required. However, the risk of retinal slippage during the exchange of PFCL for air remains a challenge. The choice of tamponade depends on the location of the GRT. Inferior GRTs can be managed with short-term PFCL use, while superior GRTs may require gas tamponade. Silicone oil tamponade is reserved for cases with existing proliferative vitreoretinopathy. The anatomical success of retinal detachment due to giant retinal tears is encouraging. However, visual recovery depends on various factors, including preoperative vision and macula involvement. Avoiding silicone oil in macula-sparing GRT detachment is recommended to optimize visual outcomes.
