Résumé
PURPOSE: In the present study, 2 cases of serous retinal detachment in patients diagnosed with proliferative diabetic retinopathy after pars plana vitrectomy are reported. CASE SUMMARY: (Case 1) A 38-year-old female diagnosed with high-risk proliferative diabetic retinopathy underwent pars plana vitrectomy and cataract surgery due to intravitreal hemorrhage. One day after the operation, fundus photograph and optical coherence tomography (OCT) revealed serous retinal detachment. After ensuring that no retinal hole was present based on fundus examination, the patient was diagnosed with serous retinal detachment and antimicrobial and steroid eye drops were applied. After 1 week, subretinal fluid disappeared. (Case 2) A 63-year-old male diagnosed with proliferative diabetic retinopathy underwent pars plana vitrectomy due to right vitreous hemorrhage. On postoperative day 1, focal subretinal fluid under the macula was observed using OCT. Intravitreal triamcinolone injection was performed during surgery and steroid eye drops were applied. Subretinal fluid collection was absorbed 5 days postoperatively. CONCLUSIONS: Two cases of serous retinal detachment that occurred postoperatively in patients with diabetic retinopathy are reported. Serous retinal detachment was resolved after several days without specific management.
