Chronic macular detachment following pneumatic retinopexy

In a consecutive series of 73 retinal detachments managed with pneumatic retinopexy, three (4.1%) of 73 eyes sustained chronic detachment of the posterior retina involving the macula even though all retinal breaks were closed. This shallow subretinal fluid persisted for 12 to 21 months but reabsorbed spontaneously. Two cases presented with a detached macula, one of which had pre-existing macular degeneration. The other case presented with an attached macula but it became detached immediately after pneumatic retinopexy. The visual acuities in the two patients who did not have macular pathology before the development of retinal detachment were 20/50 and 20/40 even with persistent subretinal fluid under the macula. In both cases the visual acuity improved to 20/30 after resolution of the subretinal fluid. Patients with a longstanding component to the retinal detachment and small retinal breaks may be at risk of developing chronic macular detachment following pneumatic retinopexy. Pockets of subretinal fluid can persist following scleral buckling, with or without drainage of subretinal fluid. However, it is unknown whether scleral buckling has a lower incidence of this complication than pneumatic retinopexy.     

Laser pneumatic retinopexy for repair of recurrent retinal detachment after failed scleral buckle--ten years experience

BACKGROUND: Although pneumatic retinopexy was introduced for the repair of primary retinal detachments, we have had excellent long-term success in employing this technique along with laser photocoagulation following failure of routine scleral buckle surgery in nonvitrectomized eyes over the last 10 years. PATIENTS AND METHODS: We categorized a consecutive series of 40 eyes that failed primary scleral buckling surgery and had at least six months follow-up. Eyes were separated into two groups: those with 1) subretinal fluid persisting or developing during the first 14 days after surgery or 2) those accumulating subretinal fluid at least 14 days after initially successful anatomic reattachment of the retina. RESULTS: In these groups, 36 of the 40 eyes (90%) were successfully reattached using outpatient pneumatic retinopexy alone. Complications were limited to the production of new retinal breaks in 5 patients. The 4 pneumatic retinopexy failures were all subsequently treated successfully with either scleral buckle revision or vitrectomy. CONCLUSION: We believe that laser pneumatic retinopexy repair of recurrent retinal detachments following scleral buckle and without significant proliferation vitreoretinopathy (PVR) should be considered ahead of conventional surgical intraoperative techniques. Laser pneumatic retinopexy may be a very successful procedure for the treatment of recurrent retinal detachments after failed scleral buckle surgery. In a consecutive series of 40 eyes with recurrent retinal detachment, we were able to repair 36 with pneumatic retinopexy alone.     

Pneumatic retinopexy. An analysis of intraoperative and postoperative complications. The Retinal Detachment Study Group

There have been 26 series (1,274 eyes) published on the use of pneumatic retinopexy for selected retinal detachments. Eighty percent were reattached with a single procedure and 98% with reoperations. New retinal breaks occurred in 13% and proliferative vitreoretinopathy in 4%. The three complications reported with pneumatic retinopexy but not with scleral buckling are subretinal gas, gas entrapment at the pars plana, and subconjunctival gas. Twenty-six complications of pneumatic retinopexy, most of which may also occur with scleral buckling, are discussed as to incidence, cause, prevention, and management.

Pneumatic retinopexy. A two-step outpatient operation without conjunctival incision

1,000 consecutive patients operated for retinal detachment were studied prospectively to determine the incidence of complications. Two parts of the operation were responsible for most of the vision-threatening complications: subretinal fluid drainage and the scleral buckle. In an attempt to reduce the complications of retinal detachment surgery, we have utilized a simplified procedure of transconjunctival cryotherapy and intravitreal gas injection with postoperative positioning. This study was limited to detachments with one or more breaks within one clock hour located within the superior eight clock hours of the fundus without signs of proliferative vitreoretinopathy. In a series of 20 consecutive patients, retinal reattachment was initially achieved in all cases. There were two recurrences that were reattached with scleral buckling. The final cure rate for the single pneumatic procedure, with six months follow-up, was 90%. No major complications were observed. This preliminary report suggests that pneumatic retinopexy has the advantages of reduced tissue trauma, no hospitalization, minimal complications, and reduced expense. The major disadvantage is the need for postoperative positioning for five days.

Pneumatic retinopexy. A collaborative report of the first 100 cases

The preliminary experience of one surgeon, using pneumatic retinopexy for 20 consecutive cases of rhegmatogenous retinal detachment, was previously reported. The collaborative experience of six surgeons using pneumatic retinopexy for 100 cases is now reported. This series includes cases with pseudophakia, aphakia, macular detachment, macular breaks, vitreous hemorrhage, trauma, and old detachments. Initially, 91% were reattached, but seven recurrences yielded a 6-month follow-up cure rate of 84% with pneumatic retinopexy. With subsequent scleral buckling, 98% were reattached. Postoperative complications included proliferative vitreoretinopathy (3%), macular pucker (3%), and new/missed retinal breaks (7%). A review of the literature disclosed postoperative new/missed retinal breaks in nine series: 21, 3, 8, 4, 9, 7, 5, 4, and 13%. There were no cases of glaucoma, cataract, subretinal gas, endophthalmitis, or extension of the detachment into a previously attached macula. Pneumatic retinopexy offers the advantages of reduced tissue trauma, fewer complications, no hospitalization, and less expense. The major disadvantage is the need for postoperative positioning.

Results of pneumatic retinopexy with air.

Although scleral buckling yields good results in retinal reattachment surgery, we search for less laborious methods which could give the same high cure rate. Fifty-one consecutive patients with phakic, rhegmatogenous retinal detachment and breaks within 60 degrees of the upper retinal quadrants were treated by retino-cryopexy, drainage of subretinal fluid (under an operating microscope), and intravitreal injection of air (0.8 to 2.0 ml). Follow-up examinations (after 6 to 12 months) disclosed retinal reattachment in 44 of 51 eyes (86%). Cases with macular detachment showed good visual recovery, and 15 of 23 eyes (65%) achieved 0.5 (20/40) or more in visual acuity. Postoperatively, new retinal breaks occurred in 6%, proliferative vitreoretinopathy in 2%, and macular pucker also in 2%. Pneumatic retinopexy with air is an easy procedure, it is associated with few complications, and enables rapid postoperative recovery.

Pars plana vitrectomy without scleral buckle for pseudophakic retinal detachments

ObjectiveTo report the anatomic and visual results of primary pars plana vitrectomy (PPV) without scleral buckling to repair primary rhegmatogenous retinal detachments in pseudophakic eyes.DesignNonrandomized, prospective, comparative clinical trial.ParticipantsTwo hundred eighty-three consecutive patients (294 eyes) with pseudophakia, peripheral retinal tears, and new rhegmatogenous retinal detachments were treated according to the surgery protocol.InterventionPatients underwent PPV with fluid-gas exchange and endolaser to repair the retinal detachment. Two hundred sixty-four patients (275 eyes) were followed from 6 months to 6 years and 8 months with an average follow-up of 19 months.Main outcome measuresReattachment of the retina and visual outcome were compared to previously published studies.ResultsOf 97 eyes with a macula-attached rhegmatogenous retinal detachment, 88 eyes (91%) were reattached with a single operation, and of the 178 eyes with a macula-detached retinal detachment, 153 (86%) eyes were reattached with a single operation. In 241 (88%) of 275 eyes, the retina was reattached with a single operation, and in 265 (96%) of 275 eyes, the retina was ultimately reattached with subsequent operations. The median initial visual acuity was 20/300, and the median final visual acuity was 20/40. The rate of reattachment with one operation was similar for eyes with an anterior chamber intraocular lens (91%) and for eyes with a posterior chamber intraocular lens (88%). Refractive error measurements obtained in 81 eyes were essentially unchanged. The mean change in refractive error was −0.15 diopter. Seventeen eyes (6%) developed macular puckers requiring surgery, 46 eyes (17%) developed cystoid macular edema, and 6 eyes (2%) developed full-thickness macular holes.ConclusionPrimary PPV with fluid-gas exchange and laser is a safe, effective method to repair primary pseudophakic retinal detachments. The anatomic reattachment rate and the visual acuity obtained with this technique appear to be at least as good as those reported in the literature for scleral buckling, PPV with scleral buckling, and pneumatic retinopexy.     

Treatment of rhegmatogenous retinal detachment in teenagers by pneumatic retinopexy technique

PURPOSE: To evaluate the effectiveness of pneumatic retinopexy as an alternative technique for rhegmatogenous retinal detachment (RD) repair in teenagers. DESIGN: Retrospective, noncomparative, interventional case series. METHODS: We conducted a review of 19 patients (19 eyes) younger than 20 years of age who had undergone pneumatic retinopexy as the initial procedure for rhegmatogenous RD between 1995 and 2002. RESULTS: Fourteen boys and five girls (mean age of 17.1 years) were included in this study. Two eyes had a history of trauma. Seventeen eyes (89.5%) had myopia of > -3 diopters. The averaged refraction of the operated eyes was -6.11 diopters (range, -1.25 to -9.5 diopters). Macular detachment was found in 13 eyes (68.4%). Subretinal fibrosis was present in six eyes (31.6%). Pneumatic retinopexy resulted in reattachment in 16 eyes (84.2%) with one injection of gas. One patient required a second injection of gas. Two patients needed additional scleral buckling to attach the retina. Displaced subretinal fluid and delayed resorption of subretinal fluid were noted in four eyes. Mean follow-up period was 42.7 months (range, six to 75 months). CONCLUSIONS: Rhegmatogenous RD in teenagers can be treated with pneumatic retinopexy with an overall successful rate as in adults. More attention is required regarding the postoperative stage and follow-up period to ensure surgical success.

Anatomical retinal reattachment after scleral buckling with and without retinopexy: a pilot study

Purpose: To compare the anatomical results of scleral buckling with and without retinopexy and to assess the effect of retinopexy on the scleral buckling outcome. Methods: This randomized clinical trial was performed on 55 patients. Twenty‐two eyes were treated with scleral buckling (segmental or encircling) with or without drainage of subretinal fluid without any type of retinopexy (group 1); 33 patients received transscleral retinal cryopexy around retinal break(s) in addition to the former procedure. The two groups were matched regarding age, sex, myopia, aphakia, stage of proliferative vitroretinopathy (PVR) and number, type and location of the break(s). Results: In the non‐retinopexy group, 19 patients (86%) had complete retinal reattachment and one patient had partial reattachment after 34–48 months of follow‐up. One patient did not develop attachment because of missed break out of the buckle, and one had no attachment at all because of PVR. Overall success rate was 91% (20 of 22) in this group. In the retinal cryopexy group, 26 patients (79%) had complete retinal reattachment and two had partial reattachment during 35–56 months of follow‐up. In two patients, no attachment was achieved because of missed break out of the buckle; three patients developed redetachment after 1 and 3 months because of PVR. Overall success rate was 85% (28 of 33). The anatomical results in these two groups were the same statistically. Conclusion: With the permanent scleral buckling technique, retinal cryopexy adds no benefit to the success rate of anatomical retinal reattachment.
