Project description:PurposeTo examine outcomes of 23-gauge (23G) pars plana vitrectomy (PPV) for complex diabetic tractional retinal detachment (TRD) in Chicago's Cook County Health and Hospitals System (CCHHS).Materials and methodsThis is a retrospective noncomparative study of diabetic TRD cases that underwent PPV at CCHHS. Primary retinal reattachment rate, visual function, and postoperative complications were analyzed.ResultsSixty nine consecutive cases were included. Primary reattachment and final attachment were achieved in 68/69 eyes (98.6%). Secondary retinal detachment was noted in 1 eye (1.4%). Vitreous hemorrhage requiring repeat PPV developed in 5 eyes (7.2%) and reoperation due to other complications was required in 4/69 eyes (5.8%). Perfluoropropane (C3F8) gas tamponade was used in 91.3% of eyes and silicone oil in 8.7% of eyes. Mean LogMAR visual acuity significantly improved from 1.84 ± 0.61 to 0.93 ± 0.66, (P<0.0001). Vision was stabilized or improved in 66 eyes (95.7%). Visual acuity of 20/200 or better was achieved in 49/69 eyes (71.0%) and 20/50 or better in 16/69 eyes (23.2%).ConclusionsEven in patients with severe and advanced diabetic TRD pathology and unique demographics as seen in CCHHS, modern vitrectomy techniques can provide excellent anatomical and visual outcomes.

Project description:Tractional retinal detachment (TRD) causes visual loss in diabetes mellitus patients. Silicone oil can be used as a tamponade to repair retinal detachment; however, intrasilicone injection is challenging. We aimed to evaluate the effect of intrasilicone bevacizumab injection in TRD surgery. This was a single-hospital, retrospective, case-control study of 44 patients (46 eyes). We reviewed medical histories and ophthalmic examination results. We administered silicone oil to 26 eyes (group I), and a combination of silicone oil and intravitreal bevacizumab injection to 20 eyes (group II). The main outcome measures were the logarithm of the minimum angle of resolution (logMAR) visual acuity and central macular thickness. Mean change in logMAR visual acuity was larger (p = 0.029) in group II (-0.99 ± 0.73) than in group I (-0.56 ± 0.80), 12 months postoperatively. Compared to group I, group II exhibited a lower mean (471.54 ± 120.14 μm vs. 363.40 ± 59.57 µm, respectively; p = 0.001), and mean change (-22.39 ± 203.99 μm vs. -72.40 ± 139.35 µm, respectively; p = 0.027), in central macular thickness, 1 month postoperatively. Intrasilicone bevacizumab injection immediately after vitrectomy may rapidly reduce central macular thickness and increase final visual acuity. Prospective studies are necessary to demonstrate long-term safety and efficacy.

Project description:PurposeTo report a case of proliferative retinopathy with tractional retinal detachment associated with beta thalassemia minor in a 27-year-old female.ObservationsA young lady having beta thalassemia minor presented with decreased vision in both eyes, the effect being more severe in her right eye. The patient's other systemic history, including ophthalmic history, was unremarkable. The fundus examination revealed peripheral retinal ischemia in both eyes and tractional retinal detachment in the right eye.ConclusionBeta thalassemia minor is not associated with striking retinal pathology, nevertheless proliferative retinopathy. However, in this case the patient developed tractional retinal detachment that required surgery. This indicates that proliferative changes may develop in patients with beta thalassemia, and routine fundus examinations could be recommended for these patients.

Project description:ImportanceThe association of proliferative diabetic retinopathy (PDR) interventions of panretinal photocoagulation (PRP) and intravitreal injections (IVIs) with tractional retinal detachment (TRD) is unclear.ObjectivesTo determine whether different treatment types or a 6-month or longer period of loss to follow-up (LTFU) is associated with TRD.Design, setting, and participantsThis nested case-control study included data from January 1, 2000, to June 30, 2021, of patients with PDR. Those who progressed to TRD were matched to non-TRD controls up to a 5:1 ratio. Exclusion criteria included 2 or fewer years in the plan, history of nondiabetic retinopathy, vitreous hemorrhage, previous RD, or any other surgically indicated diagnosis. Patient data were obtained from a deidentified commercial and Medicare Advantage medical claims database. Statistical analysis was performed from January to May 2022.ExposuresPrimary exposures of interest were prior treatment (PRP, IVI, both) and any period of 6 months or longer in which the patient received no eye care.Main outcomes and measuresOdds ratios (ORs) of IVI only compared with PRP and 6-month or longer LTFU on development of TRD.ResultsAfter application of inclusion and exclusion criteria, a total of 214 patients (mean [SD] age, 55.6 [12.4] years; 115 female [53.7%]) with PDR and TRD were matched to 978 controls (mean [SD] age, 65.6 [11.3] years; 507 female [51.8%]) with only PDR. Among patients with TRD, 69 (32.2%) were treated with laser only, 17 (7.9%) were treated with injection only, 39 (18.2%) were treated with both, and 89 (41.6%) had no prior treatment. Among patients in the PDR-only group, 207 (21.2%) received laser only, 83 (8.5%) received injection only, 57 (5.8%) received both, and 631 (64.5%) received no treatment. After adjusted analysis, no difference in odds of TRD for patients who received injection only compared with patients who received laser only was found (adjusted OR [aOR], 0.56; 95% CI, 0.27-1.14). Patients who received both treatments had higher odds of TRD compared with those who received laser only (aOR, 2.33; 95% CI, 1.21-4.48), and patients who had no treatment had lower odds of TRD (aOR, 0.46; 95% CI, 0.29-0.71; P < .001 for treatment category). Similarly, no difference was seen in the odds of TRD between those with LTFU for 6 months or longer and those without LTFU (aOR, 0.72; 95% CI, 0.49-1.07; P = .11).Conclusions and relevanceResults of this case-control analysis suggest that there is no increased risk of TRD associated with IVI-only treatment or with 6-month or longer periods of LTFU, which supports the findings of other investigations. Nonetheless, LTFU rates continue to remain high in patients with PDR, which can contribute to substantial vision loss regardless of treatment regimen.

Project description:BackgroundTo compare the safety and efficacy of Ab-externo subretinal bands removal in comparison with the classical Ab-interno approach during pars plana vitrectomy for primary rhegmatogenous retinal detachment.MethodsSubjects aged 28-62 years with primary RRD complicated by proliferative vitreoretinopathy (PVR) with subretinal bands interfering with retinal flattening were treated by pars plana vitrectomy (PPV) and silicone oil injection. Subretinal bands were removed using the classical AB interno approach through one or more retinotomies in ten patients (group A) and using AB externo approach in twenty cases (group B). Post-operative follow-up visits occurred at 1 day, 1 week, 1 month, and 3 months, after surgery. The main outcomes were assessment of subretinal bands removal efficacy, documentation of complications, anatomical reattachment rate, and postoperative best-corrected visual acuity (BCVA).ResultsThere was no statistically significant difference between both groups regarding patients' age, gender, lens status, and the onset of retinal detachment. Seventy percent of both groups presented with inferior retinal detachment while ten percent presented with temporal detachments and twenty percent had a total retinal detachment. Both groups had a statistically significant improvement in postoperative visual acuity in comparison with preoperative visual acuity (P = 0.005 for group A and P = < 0.001 for group B). There was no statistically significant difference between both groups regarding preoperative (P = 0.928) and postoperative (P = 0.185) visual acuity. A higher incidence of complications was reported in group A (40%) in comparison with group B (30%) but this difference was not statistically significant (P = 0.69). More Epimacular membranes were seen postoperatively in group A (30%) in comparison with group B (20%) but again this difference was not statistically significant (P = 0.657). Subretinal hemorrhage was seen in ten percent of cases in both groups. Intraocular pressure was measured in every follow-up of all patients in both groups, no statistically significant difference was found between both groups.ConclusionsBoth techniques are effective and safe to remove subretinal bands with similar outcomes.

Project description:BackgroundTo report our experience using 27-gauge pars plana vitrectomy (PPV) system for treating patients with combined tractional and rhegmatogenous retinal detachments (CTRRD) involving the macula associated with proliferative diabetic retinopathy (PDR).MethodsRetrospective noncomparative interventional cases series of 12 patients with CTRRD associated with PDR who underwent 3-port, transconjunctival 27-gauge PPV by a single surgeon. Main outcome measures were change in Snellen best corrected visual acuity (BCVA) and occurrence of intra- and post-operative complications.ResultsTwelve eyes from 12 patients (9 men and 3 women) underwent 27-gauge PPV. Mean follow-up was 17 months (range 8-26 months). Preoperatively, BCVA of 20/400 or better was recorded in only 2 of 12 (16.7%) eyes. Postoperatively, BCVA improved to 20/400 or better in 11 of 12 (91.7%) eyes at 6 months (P = 0.001). At last follow-up, BCVA of 20/400 or better was recorded in 10 of 12 (83.3%), in comparison to 2 (16.7%) eyes at baseline (P = 0.004). The only intraoperative complication was an iatrogenic break in 1 eye (8.3%). Postoperative complications included vitreous hemorrhage in 4 eyes (33.3%) and transient ocular hypertension in 3 eyes (25.0%). At final follow-up anatomic success was confirmed in all eyes.ConclusionThe current study findings suggest that 27-gauge PPV is a safe and promising surgical technology for treating patients with CTRRD involving the macula associated with PDR. Smaller gauge instruments and higher cutting rates may facilitate the dissection and shaving of fibrovascular membranes, while minimizing intra- and post-operative complications.

Project description:ObjectiveTo compare surgical outcomes between 27 and 25-gauge vitrectomy in proliferative diabetic retinopathy (PDR) with tractional retinal detachment (TRD).MethodsThis retrospective study was conducted to compare the intraoperative status, operation time, use of instruments, endotamponade substance, wound suture number, and iatrogenic break, between 27 and 25-gauge vitrectomy in 43 eyes afflicted by PDR with TRD. The post-surgical results, best-corrected visual acuity, intraocular pressure, recurrent vitreous haemorrhage, and re-operation rate were regularly followed up for 6 months.ResultsPatients in the 25 and the 27-gauge groups did not differ significantly in terms of pre-surgical conditions, such as age, gender, pre-existing glaucoma, best-corrected visual acuity (BCVA) and the severity of their TRD. The mean operation time was 56.7 minutes in the 27-gauge group and 63.7 minutes in the 25-gauge group (p = 0.94). There is significantly less use of micro forceps in the 27-gauge group (p = 0.004). No difference between micro scissors and chandelier usage were noted; neither was their difference in iatrogenic retinal breaks. Significantly fewer wound sutures were noted in the 27-gauge group (p < 0.001). The post-operative results revealed no significant difference in ocular hypertension, hypotony, BCVA improvement, recurrent vitreous haemorrhage and re-operation rate.ConclusionsThe 27-gauge vitrectomy system offers comparable surgical outcomes in PDR with TRD. The 27-gauge vitrectomy system is suitable for complicated retinal surgery.

Project description:PurposeTo describe the ophthalmic presentation and management of a male infant with homozygous protein C deficiency (PCD).MethodsCase report.ObservationAn 8-week-old male infant presented with bilateral vitreous hemorrhage and tractional retinal detachment in the right eye. Work up revealed low protein C levels. Whole exome sequencing showed a homozygous likely pathogenic variant in PROC gene. The management included laser photocoagulation to both eyes followed by lens-sparing vitrectomy with membrane peeling to the right eye. Successful outcome was achieved in both eyes.Conclusion and importanceCongenital PCD is a rare life-threatening disease that usually presents in infancy with purpura fulminans or disseminated intravascular coagulation. However, ophthalmologists should be aware of this condition, as its ocular signs may appear first. Early recognition, laser therapy of the attached ischemic retina and early vitrectomy may be successful in achieving good anatomical and functional outcomes.

Project description:To evaluate the outcome of scleral buckling surgery in patients with rhegmatogenous retinal detachment (RRD) with subretinal proliferation.In this retrospective study, a chart review of all patients with RRD associated with subretinal proliferation who were primarily treated with scleral buckling procedure, from April 2007 to April 2014, was undertaken. Main outcome measures were anatomical retinal reattachment and visual acuity.Forty-four eyes of 43 patients including 24 males and 19 females with a mean age of 26.5±13.1 years were evaluated. Immediately after the surgery, retina was reattached in all eyes. However, five eyes (11.3%) needed additional surgery for retinal redetachment. Single surgery anatomical success rate was 88.7%. Four eyes (9.1%), needed pars plana vitrectomy for the treatment of redetachment associated with proliferative vitreoretinopathy and scleral buckle revision surgery was successfully performed in the other eye. Best corrected visual acuity improved from 1.5±0.9 logMAR before surgery to 1.1±0.7 logMAR after surgery (P<0.001). An improvement in BCVA of >2 lines was found in 23 eyes (52.2%) and worsening of best corrected visual acuity of >2 lines was observed in 2 eyes (4.5%).Scleral buckling surgery is highly successful in eyes with RRD associated with subretinal proliferation.

Project description:BackgroundTo report a case with bilateral Terson syndrome presented with a unique mushroom-like mass lesion on the optic disc along with proliferative vitreoretinopathy and tractional retinal detachment.Case presentationA 33-year-old man was injured during a traffic accident and had diffuse brain swelling and intraocular hemorrhage. Poor vision in both eyes was noted after the patient regained consciousness. B-scan ultrasonography showed extensive vitreous opacity with a posterior vitreous detachment and without obvious retinal detachment. Vitrectomy was performed in both eyes five months after the accident. After clearing up the vitreous opacity, a peculiar pigmented mushroom-like mass lesion was noted in the posterior pole and had severe adhesion to the underneath optic disc. Extensive multilayered peripapillary epiretinal membrane was found covering the posterior pole and led to tractional retinal detachment around the macula. The mass was presumed to be an organized vitreous hemorrhage originated from the optic disc. The extensive and adherent epiretinal membrane together with the mass lesion were removed as much as possible and silicon oil was injected for tamponade. However, in the right eye, the retina redetached under silicon oil, whereas in the left eye, his vision improved to 20/100.ConclusionsTerson syndrome usually has a favorable prognosis but may be complicated by proliferative vitreoretinopathy and tractional retinal detachment. Careful monitoring is warranted and early vitrectomy should be considered in cases suspecting additional pathologies.
