Therapeutic effect of suprachoroidal viscoelastic injection combined with 532 laser photocoagulation in treating rhegmatogenous retinal detachment.

PURPOSE: To assess the therapeutic effect of suprachoroidal viscoelastic injection combined with 532 laser photocoagulation for the closure of retinal tears in the treatment of rhegmatogenous retinal detachment (RRD).

METHODS

We retrospectively analyzed the clinical data of eight patients with RRD (eight eyes) who underwent suprachoroidal viscoelastic injection combined with 532-nm laser photocoagulation for the closure of tears at our hospital. The outcomes investigated were postoperative visual acuity and retinal reattachment.

RESULTS

The intraocular pressure (IOP) was significantly higher after surgery than before surgery (11.93 mmHg vs. 19.50 mmHg), and the best corrected visual acuity (BCVA) changed from 0.41 to 0.49, suggesting a significant improvement within 3 days post-surgery. In 7/8 eyes, the retina was well reattached postoperatively and follow-ups indicated stable condition. One patient experienced failed retinal reattachment and subsequently underwent vitrectomy combined with silicone oil tamponade. Three months after surgery, the silicone oil was removed, revealing successful reattachment of the retina.

CONCLUSION

In patients with RRD characterized by smaller retinal tears, more localized retinal detachment, and a proliferative vitreoretinopathy grade of ≤ C1, treatment incorporating suprachoroidal viscoelastic injection and 532-nm laser photocoagulation to seal the tears resulted in good postoperative recovery, with all patients achieving favorable visual acuity. However, due to the retrospective, non-comparative design without a control group, it is difficult to fully evaluate the relative efficacy of this treatment compared to other methods.
