研究目的: |
孔源性视网膜脱离(RRD)是一种严重威胁视力的眼科疾病,需要及时有效的治疗。充气性视网膜固定术(Pneumatic Retinopexy,PR)作为一种相对微创的治疗方法,近年来在临床上得到了一定的应用。本研究旨在通过临床试验,观察充气性视网膜固定术治疗孔源性视网膜脱离的临床疗效,包括解剖成功率、视力恢复情况、并发症发生率以及患者的生活质量改善情况,以期为临床治疗提供更科学的依据。 |

|
Objectives of Study: |
Rhegmatogenous retinal detachment (RRD) is a sight-threatening ophthalmic condition requiring prompt and effective treatment. As a relatively minimally invasive treatment approach, pneumatic retinopexy (PR) has seen increasing clinical use in recent years. This study aims to conduct a clinical trial to evaluate the clinical efficacy of pneumatic retinopexy in treating rhegmatogenous retinal detachment, including anatomical success rate, visual acuity recovery, incidence of complications, and improvement in patients' quality of life, thereby providing a more scientific basis for clinical management. |

Description for medicine or protocol of treatment in detail: |
Pneumatic Retinopexy Topical anesthesia was administered using 0.1% Oxybuprocaine Hydrochloride eye drops, applied once every 5 minutes for a total of 3 doses. Following routine disinfection and draping, a 15-degree keratome was used to perform an anterior chamber paracentesis at the temporal inferior corneal limbus. The posterior lip of the incision was compressed to release an appropriate amount of aqueous humor, thereby reducing intraocular pressure. A 26G needle was inserted into the vitreous cavity 3.5–4.0 mm posterior to the corneal limbus on the side opposite to the highest point of retinal detachment. The needle was advanced 2–3 mm into the vitreous cavity, and its entry was confirmed by visualization through the pupillary area. Filtered air (0.5–0.6 mL) was slowly and steadily injected to form a gas bubble. After completing the injection, the needle was withdrawn smoothly, and the puncture site was closed with microforceps. Simultaneously, the eye was gently rotated to position the gas bubble over the retinal break.At the conclusion of the procedure, digital palpation confirmed normal intraocular pressure. Ioban ophthalmic ointment was applied to the conjunctival sac, and the eye was covered with a pressure patch. Postoperative instructions emphasized maintaining a positioning regimen to ensure the retinal break remains in the uppermost position.Either postoperative laser therapy or intraoperative cryotherapy may be chosen to seal the retinal break. Scleral Buckling Procedure Administer 4 ml of 2% lidocaine + 0.75% bupivacaine.Routinely disinfect the surgical eye and surrounding skin with povidone-iodine. Place a sterile drape and insert an eyelid speculum to expose the eye.Circumferentially incise the bulbar conjunctiva along the corneal limbus. Perform blunt dissection of Tenon’s capsule to expose the sclera.Use a muscle hook to engage the rectus muscle in the corresponding quadrant. Secure it with sutures for traction and fixation, fully exposing the surgical field. Depress the sclera with a scleral depressor. Confirm the position of the retinal break under indirect ophthalmoscopy and mark it on the scleral surface.Place a silicone sponge explant and pre-fix it with 6-0 non-absorbable sutures in a mattress pattern through the scleral lamellae.Under indirect ophthalmoscopy guidance, apply the retinal cryoprobe around the retinal break to induce cryotherapy.Tie the sutures to fix the buckling material, ensuring the break lies on the anterior slope of the buckling ridge.Verify complete closure of the break, ideal positioning of the buckling ridge, and retinal reattachment. Reposition the rectus muscle. Continuously suture the bulbar conjunctiva with 8-0 absorbable sutures. |
