UNASSIGNED: Posterior subtenon injection of triamcinolone acetonide (PSTA) is commonly done to treat refractory cases of macular edema. Complications may arise from the procedure as well as from the use of the periocular steroid medications. Side effects include subconjunctival hemorrhage, progression of cataract, scleral perforation (resulting in subretinal, subhyaloid, or intravitreal injection of the drug), retinal detachment, ptosis, orbital fat prolapse, orbital abscess, infectious scleritis, ocular hypertension, and scleral abscess. Here we describe a case of inadvertent subretinal triamcinolone acetonide (TA) deposition from a PSTA procedure without any adverse vision-threatening outcomes.
UNASSIGNED: We report a patient who presented with a history of superior temporal left eye macula-off rhegmatogenous retinal detachment, which was successfully repaired with a scleral buckle (SB), pars plana vitrectomy, and gas placement. Due to persistent diplopia, the SB was removed after 1 year post-operatively. Due to the development of cystoid macular edema, a PSTA was performed after the patient failed topical steroids and NSAIDs. The procedure was halted early due to unexpected resistance during the injection. A dilated fundus exam showed the presence of subretinal triamcinolone acetonide. The patient was observed and found to have no complications with almost complete resolution of the triamcinolone acetonide after 3 months.
UNASSIGNED: In previous SB patients, it is important to highlight the risk of globe penetration, subretinal deposition of TA, formation of retinal breaks, or reopening of prior retinal breaks with posterior subtenon injection, which could have adverse effects on the local retina as well as the risk of retinal detachment.

Rhegmatogenous retinal detachment (RRD) is an ocular emergency as it is sight-threatening and requires urgent surgical intervention. Ulcerative colitis (UC) is an immune-mediated inflammatory bowel disease that can present with ocular manifestations. The objective of this case report is to share the rare presentation of RRD associated with UC leading to diagnosis and management dilemmas. A 35-year-old man with active UC presented with a right chronic red eye for two months. The best corrected visual acuity (BCVA) was 6/6 in both eyes (OU). On examination, sectoral inferotemporal anterior scleritis (AS) with subclinical inferior RRD with peripheral holes in the lattice at the 6 o\'clock position was noted. There was no posterior vitreous detachment. Optical coherence tomography (OCT) delineated the RRD objectively and was non-progressive for nine months. Barricade laser was given, in addition to intravenous methylprednisolone (IVMP), followed by a tapering dose of oral prednisolone and topical dexamethasone 0.1% over three months. Over a year, the scleritis resolved. However, six months later, while still on immunomodulating agents, the inferior RRD progressed on OCT. Segmental scleral buckle, indirect laser retinopexy, and subtenon triamcinolone injection were performed. IVMP 1 g per day was given for three days prior to surgery. Two months later, his BCVA was 6/6, with signs of fluid resorption and normal intraocular pressure. No recurrent AS was seen. Treatment of non-progressive, subclinical RRD patients with UC and active AS can be delayed with regular follow-up. When RRD progressed and there was no AS activity, it was the window of opportunity for the success of scleral buckle and perioperative steroids.

Scleral buckle (SB) removal is done for a variety of reasons following treatment of rhegmatogenous retinal detachments (RRD), such as buckle exposure, migration, and infection. The most worrying complication of SB removal is retinal redetachment. We report a unique case of a patient developing strabismus about one month after scleral buckle removal for anterior migration and exposure of the scleral buckle. We also share a successful strabismus surgery which had a main aim of relieving diplopia in the patient\'s primary gaze.

UNASSIGNED: To investigate refractive, visual, and safety outcomes of cataract surgery performed after scleral buckling (SB) for retinal detachment (RD).
UNASSIGNED: A chart review at an academic medical center identified eyes with history of SB followed by subsequent cataract extraction between 2010 and 2022. Eyes with less than 3 weeks follow-up, silicone oil at time of biometry measurement, previous cornea surgery, or co-existing pathology impacting refractive outcomes were excluded. Predicted postoperative spherical equivalents (SE) were calculated with the Barrett Universal II (BU2), Kane, and SRK/T formulas for the implanted intraocular lens (IOL), and complications occurring within 1 year of surgery were abstracted.
UNASSIGNED: Sixty eyes of 60 patients met criteria for inclusion, and 40 (66.7%) had postoperative refraction recorded. Absolute prediction errors were 0.49, 0.45, and 0.52D with BU2, Kane, and SRK/T, respectively. Actual postoperative refraction was within 0.5 and 1.0 D of predicted in 26 (65.0%) and 36 (90.0%) using BU2, 23 (58%) and 37 (93%) using Kane, and 21 (52.5%) and 36 (90.0%) using SRK/T. In eyes with macula-on RD, corrected distance visual acuity (CDVA) of logMAR 0.301 (≈20/40) and logMAR 0.544 (≈20/70) or better was achieved in 12 (75.0%) and 15 (93.8%) of eyes. For macula-off RD eyes, these proportions were 19 (63.3%) and 24 (80.0%), respectively. Posterior capsular opacification requiring Nd: YAG capsulotomy was the most frequent complication in 30 (56.7%) eyes.
UNASSIGNED: Refractive outcomes of cataract surgery following SB may be modestly reduced, even when using modern formulas. Nevertheless, cataract surgery in this population results in favorable visual outcomes.
The retina is the part of the eye that is responsible for converting incoming light into a signal that the brain can interpret. A retinal detachment is an emergent condition in which the retina is torn away from its normal position. Scleral buckling is one method of surgically reattaching the retina. Although quite successful, scleral buckling can cause changes to the shape of the eye, and also increases the risk of opacification of the natural lens of the eye, otherwise known as a cataract. The purpose of this study is to investigate the outcomes of cataract surgery in eyes with prior scleral buckle surgery. The results show that despite advancements in methods of measuring the shape of the eye, calculating the appropriately powered IOL to implant, and surgical technique, cataract surgery in eyes with prior scleral buckling may result in poorer outcomes compared to eyes with no history of scleral buckling.

Introduction: Intraocular surgeries are conventionally contraindicated for patients with active retinoblastoma (Rb) due to the potential risk of tumor dissemination. However, surgery is occasionally necessary to preserve vision in patients with a single eye when the eye is complicated by rhegmatogenous retinal detachment (RRD). Objective: This study aims to evaluate the outcomes of surgical repair for RRD in pediatric patients with active Rb utilizing a non-drainage scleral buckling approach. Results: This cohort included six eyes from six patients who harbored active Rb and presented with RRD; one had a concurrent tractional component. All eyes (100%) had active intraocular Rb and were undergoing active therapy (systemic chemotherapy, cryotherapy, and thermal laser therapy) when RRD developed. RRD consistently manifested at the site of recent cryotherapy in all cases. RRD repair in the affected eyes was performed by scleral buckling without subretinal fluid drainage. Five of the six eyes (83%) achieved complete retinal reattachment. One eye (17%) with a tractional component exhibited partial reattachment and was eventually enucleated due to persistent active disease. At a median follow-up of 15 months (range 12-180 months) after scleral buckling, all five eyes had persistent retinal attachment, and no case developed orbital or distant metastasis. Conclusions: Our study demonstrates that nondrainage scleral buckling is an effective and safe method for the surgical repair of RRD in eyes harboring active Rb, as most cases achieved persistent complete retinal reattachment without the risk of tumor spread.

BACKGROUND: This study aimed to investigate the incidence of and risk factors for epiretinal membrane (ERM) formation following primary rhegmatogenous retinal detachment (RRD) repair.
METHODS: This comparative, retrospective, single-center cohort study included eyes with primary RRD treated between 2011 and 2023 at Massachusetts Eye and Ear, Boston, Massachusetts, with pars plana vitrectomy (PPV), scleral buckle (SB), PPV+SB, or pneumatic retinopexy (PnR). Demographic, clinical, and surgical parameters were collected from medical records. The primary outcome was the risk of ERM formation, while the secondary outcome was the risk of ERM requiring surgery. Univariable and multivariable Cox regression were performed, and a hazard ratio (HR) and 95% confidence interval (95% CI) were reported.
RESULTS: Overall, 394 eyes were included. The mean age was 58.49 ± 12.8 years, and most patients were male. There was a significantly lower risk of ERM formation following SB compared to PPV in the univariable analysis (HR = 0.2, 95% CI = 0.08-0.60, p = 0.003); however, there was no significant association between treatment modality and ERM formation on multivariable Cox regression controlling for confounding factors (p = 0.24). ERM formation was found more commonly in patients who were older (HR = 1.0 per 1 year increase in age, 95% CI = 1.01-1.04, p = 0.001), those with worse baseline visual acuity (HR = 1.3, 95% CI = 1.09-1.71, p = 0.008), and those with macula-off RRDs (HR = 2.1, 95% CI = 1.41-3.32, p < 0.001).
CONCLUSIONS: Surgical modality does not have a significant impact on the risk of ERM following retinal detachment repair. However, age, baseline visual acuity, and macular status are important predictors of ERM formation after RRD repair.

UNASSIGNED: We report a patient with pseudoxanthoma elasticum (PXE) with angioid streaks near a scleral buckle site.
UNASSIGNED: A 46-year-old male with PXE presented for evaluation of blurry vision and was found to have classic PXE findings in both eyes and angioid streaks adjacent to the site of a scleral buckle in his left eye. He underwent multimodal imaging, genetic testing, and intravitreal aflibercept in the right eye.
UNASSIGNED: Bruch\'s membrane is known to be fragile in PXE, and patients are often counseled about the heightened risk of playing contact sports. This report raises the question of whether tension from a scleral buckle in the setting of a calcified and brittle BM may increase the likelihood of angioid streaks near the buckle site. In the setting of retinal detachment, it may be worthwhile to carefully weigh the pros and cons of vitrectomy versus buckle for PXE patients.

Purpose: To assess the visual and anatomic outcomes of eyes that had secondary scleral buckle (SB) surgery after unsuccessful pneumatic retinopexy (PR) for rhegmatogenous retinal detachment (RRD). Methods: A retrospective study, performed over a 12-year period, comprised patients who had secondary SB procedures after failed primary PR. Clinical parameters (eg, best-corrected visual acuity [BCVA], lens status, macula status, details of RRD and subretinal fluid) were assessed at presentation, before additional procedures, and at follow-up (6 months, 1 year, and last visit). Statistical comparisons were made using Brown-Forsythe and Welch analysis-of-variance tests, with significance levels set at P < .05. Results: Fifty-four eyes with adequate follow-up were included. Forty-four (81.5%) of 54 eyes had successful retinal reattachment with secondary SB alone. The remaining eyes had subsequent pars plana vitrectomy (PPV). Patients presenting with macula-on RRD who had successful secondary SB had no statistically significant change in BCVA from baseline (mean final, 0.23 ± 0.25 logMAR [Snellen 20/34]; P = .999). There was a statistically significant improvement in BCVA in patients presenting with macula-off RRD who had successful secondary SB (mean final, 0.32 ± 0.36 logMAR [20/42]; P < .001 and mean change, -1.06 ± 0.85 logMAR). Ten patients presenting with macula-off RRD who had failed secondary SB had a significant improvement in the final BCVA (mean final, 0.22 ± 0.28 logMAR [20/33]; P = .044), despite the need for an additional PPV to achieve reattachment. Conclusions: Secondary SB remains a good option for RRD repair after unsuccessful PR and may avoid the need for PPV.

Purpose: To examine the outcomes of chandelier endoillumination-assisted scleral buckling (chandelier scleral buckling) for rhegmatogenous retinal detachments (RRDs) and compare them with those of standard scleral buckling using indirect ophthalmoscopy. Methods: A literature search was performed on April 15, 2023. Outcomes analyzed included the primary anatomic success rates, surgical duration, and complication rates. A meta-analysis of proportions estimated the pooled success rate of chandelier scleral buckling. In addition, meta-analyses compared the success rates between pseudophakic eyes and phakic eyes having chandelier scleral buckling and compared success rates and surgical duration between standard scleral buckling and chandelier scleral buckling. Results: Thirty studies with 1133 eyes were included. The pooled primary anatomic success rate of chandelier scleral buckling was 91.7% (95% CI, 89.6%-93.6%). In studies comparing success rates between the 2 techniques, there was no significant difference (risk ratio, 1.01; 95% CI, 0.94-1.08; P = .80). The surgical times were significantly shorter with chandelier scleral buckling than with standard scleral buckling (mean difference, -18.83; 95% CI, -30.88 to -6.79; P = .002). There was no significant difference in the success rate between pseudophakic eyes and phakic eyes (risk ratio, 0.99; 95% CI, 0.91-1.08; P = .89). No cases of endophthalmitis were reported. Conclusions: Chandelier endoillumination-assisted scleral buckling may be a promising technique given its high rate of primary anatomic success for RRDs and success rates similar to those of standard scleral buckling. There was no significant difference in the efficacy of chandelier scleral buckling between pseudophakic eyes and phakic eyes.

UNASSIGNED: Coats disease is a rare vasculature pathology that usually presents as retinal telangiectasia with possible progression to exudative retinal detachment (RD). Intravitreal anti-VEGF injections, cryotherapy, laser photocoagulation, and surgery are commonly used to control the disease and prevent its progression. Although iatrogenic tractional RDs secondary to anti-VEGF injections have been reported in patients with Coats disease, RDs in Coats disease are exudative, secondary to retinal exudation and vascular abnormalities. In this article, we present the first reported case of a severe exudative RD accompanied by retinal traction and two retinal holes in a patient with Coats disease.
UNASSIGNED: A 32-year-old male initially presented with Coats disease stage 2A, which then progressed to 3A1 within a month of close follow-ups, finally leading to exudative RD. Following cryotherapy and bevacizumab injections, the exudative RD progressed, with the emergence of retinal traction and two retinal holes. This complex case was successfully treated with a scleral buckle vitrectomy accompanied by radial elements to support the RD, pars plana vitrectomy, silicon oil tamponade, and post-surgical bevacizumab injections. Six months following the surgical intervention, the patient\'s vision is restored at 20/30, and retinal imaging shows a totally flattened retina.
UNASSIGNED: We present the first reported case of a severe exudative RD accompanied by retinal traction and two retinal holes in a patient with Coats disease. The combination of surgical treatment and bevacizumab injections is thought to have collectively contributed to our patient\'s favorable outcome.
