RESUMO

PURPOSE: To report the result of strabismus surgery in eye-salvaged retinoblastoma (Rb) patients. METHODS: A retrospective case series including 18 patients with Rb and strabismus who underwent strabismus surgery after completing tumor treatment by a single pediatric ophthalmologist. RESULTS: A total of 18 patients (10 females and 8 males) were included with a mean age of 13.3 ± 3.0 (range, 2-39) months at the time tumor presentation and 6.0 ± 1.5 (range, 4-9) years at the time of strabismus surgery. Ten (56%) patients had unilateral and 8(44%) had bilateral involvement and the most common worse eye tumor's group was D (n = 11), C (n = 4), B (n = 2) and E (n = 1). Macula was involved by the tumors in 12 (67%) patients. The tumors were managed by intravenous chemotherapy (n = 8, 47%), intra-arterial chemotherapy (n = 7, 41%) and both (n = 3, 17%). After complete treatment, the average time to strabismus surgery was 29.9 ± 20.5 (range, 12-84) months. Except for one, visual acuity was equal or less than 1.0 logMAR (≤ 20/200) in the affected eye. Seven (39%) patients had exotropia, 11(61%) had esotropia (P = 0.346) and vertical deviation was found in 8 (48%) cases. The angle of deviation was 42.0 ± 10.4 (range, 30-60) prism diopter (PD) for esotropic and 35.7 ± 7.9 (range, 25-50) PD for exotropic patients (P = 0.32) that after surgery significantly decreased to 8.5 ± 5.3 PD in esotropic cases and 5.9 ± 6.7 PD in exotropic cases (P < 0.001). The mean follow-up after surgery was 15.2 ± 2.0 (range, 10-24) months, in which, 3 (17%) patients needed a second surgery. CONCLUSION: Strabismus surgery in treated Rb is safe and results of the surgeries are acceptable and close to the general population. There was not associated with tumor recurrence or metastasis.

RESUMO

BACKGROUND: Management guidelines and corresponding survival data for patients with recurrent retinoblastoma (RB) are lacking. This study aimed to summarize the clinical characteristics of patients with recurrent RB and analyze their survival outcomes. METHODS: We retrospectively analyzed 68 patients with recurrent RB who underwent treatment in our institution from January 2016 to December 2020. Patients were grouped according to location of recurrence: intraocular, orbital, and distant metastasis. RESULTS: The male:female ratio was 1.3:1 and the median age at recurrence was 37.5 months (range, 30.3-62.8). The number of patients in the intraocular recurrence, orbital recurrence, and metastasis groups was 13 (19.1%), 23 (33.8%), and 32 (47.1%), respectively. Thirty patients died, 36 were alive at last follow-up, and two were lost to follow-up. Eye enucleation was performed in 94.1% of patients. Five-year overall survival in patients with intraocular recurrence, orbital recurrence, and metastasis was 84.6%, 69.6%, and 31.3%, respectively (P = 0.001). Most deaths occurred within 2 years of recurrence. Presence of high-risk pathological factors, central nervous system invasion, and absence of combination therapy were independent predictors of worse 5-year overall survival. CONCLUSION: The rate of eye preservation in survivors of recurrent RB was very low. Although 5-year overall survival in patients who underwent treatment for intraocular and orbital recurrence was high, it was low in those with metastasis. RB patients may need lifelong follow-up for recurrence and secondary malignancy.

RESUMO

PURPOSE: Enucleation is a common treatment modality performed for pediatric retinoblastoma patients, and the resultant defects are reconstructed using an ocular prosthesis. The prostheses are modified or replaced periodically, as the child develops due to orbital growth and patient-error. The purpose of this report is to evaluate the replacement frequency of prostheses in the pediatric oncologic population. METHODS: A retrospective review was completed by the two senior research investigators, of patients that had ocular prostheses fabricated following enucleation of their retinoblastoma from 2005 to 2019 (n = 90). Data collected from the medical records of the patient included the pathology, date of surgery, date of prosthesis delivery, and the replacement schedule of the ocular prosthesis. RESULTS: During the 15-year study period, 78 enucleated observations (ocular prosthesis fabricated) were included for analysis. The median age of the patients at the time of delivery of their first ocular prosthesis was calculated to be 2.6 years (range 0.3-18 years). The median time to the first modification of the prosthesis was calculated to be 6 months. The time to modification of the ocular prosthesis was further stratified by age. CONCLUSION: Pediatric patients require modification of their ocular prostheses throughout their growth and development period. Ocular prostheses are reliable prostheses with predictable outcomes. This data is helpful to set an expectation among the patient, parent, and provider.

RESUMO

PURPOSE: To report the clinicopathological findings of retinal vasoproliferative tumor/reactive retinal astrocytic tumor (VPT/RRAT) with retinal vasculitis, treated by tumor resection. METHODS: A retrospective single case report. PATIENT: A 29-year-old Japanese woman was referred with cystoid macular edema and retinal vasculitis in the right eye. Best-corrected visual acuity was 0.9. Results of fundus examination, optical coherence tomography, and fluorescein angiography demonstrated VPT/RRATs in the temporal retina surrounded by a subretinal exudate, serous retinal detachment and macular edema, and retinal vasculitis. Despite 3 months of oral prednisolone treatment, a full-thickness macular hole developed. Pars plana vitrectomy and endoresection of the VPT/RRATs were performed. Pathologic and immunohistochemical analyses with anti-CD34 antibody, antiglial fibrillary acidic protein antibody, anti-Ki67 antibody, and anti-vascular endothelial growth factor antibody were performed on the excised tissue. Inflammation was evaluated by immunohistological staining with leukocyte common antigen (LCA), anti-CD3 antibody, and anti-CD20 antibody. RESULTS: After surgery, the macular hole closed, best-corrected visual acuity improved to 1.2, retinal vasculitis was ameliorated, and retinal exudate disappeared. There was no recurrence of VPT/RRAT or retinal vasculitis. Pathologic examination showed that antiglial fibrillary acidic protein and anti-vascular endothelial growth factor were widely expressed, irrespective of the distribution of blood vessels. Ki67-positive proliferating cells were detected in the perivascular area. Leukocyte common antigen-positive leukocytes and CD3-positive T cells were detected throughout the samples, whereas CD20-positive B cells were rarely detected. CONCLUSION: Endoresection of VPT/RRAT could be a good treatment option for secondary VPT/RRAT accompanied by retinal vasculitis. Pathologic findings revealed for the first time that inflammatory cells infiltrate the tissue in secondary VPT/RRAT.

RESUMO

Purpose: We evaluated the anatomical and functional outcomes after vitreoretinal surgery for complex retinal capillary hemangioblastoma (RCH). Methods: This was a retrospective case series of 15 patients (16 eyes) with tractional or combined retinal detachment (RD) managed with pars plana vitrectomy and tumor endoresection (ER) with/without feeder vessel ligation. Results: The mean age at the time of surgery was 30 years (range, 14-46 years). The most common tumor locations were inferotemporal (six eyes) and temporal (six eyes) quadrants. Indications for surgery included exudative RD with fibrovascular proliferation (eight eyes), combined RD (five eyes), vitreous hemorrhage (four eyes), and rhegmatogenous RD (two eyes). Tumor destruction was performed with laser and/or cryotherapy in nine eyes (57%) and ER in seven eyes (43%). Feeder vessel was ligated and cauterized in 10 (63%) and six eyes (37%), respectively. Anatomical success after initial surgery was 50% (eight eyes), which improved to 88% (14 eyes) after they underwent a repeat procedure for recurrent RD (eight eyes). At the last visit, visual acuity improved in seven eyes (44%), was stable in four eyes (25%), and worsened in five eyes (31%) with a mean follow-up of 29 months (6-79 months). Comparison between the ER group and the laser/cryotherapy group revealed no significant difference in final retinal reattachment rate (89% vs. 86%, P > 0.05), with better visual outcomes in laser/cryotherapy group (57% vs. 78%, P < 0.05). Conclusion: Pars plana vitrectomy with/without tumor endoresection can be a safe and effective treatment option for complex RCHs, achieving good tumor control and anatomical success with limited functional success.

RESUMO

We report the case of a 60-year-old woman who presented with metamorphopsia and progressive vision loss in the right eye. Fundus examination revealed an elevated, white-yellow mass in the peripheral inferotemporal retina, with massive retinal exudation, proliferative vitreoretinopathy, and retinal detachment. Pars plana vitrectomy with tumor endoresection was performed, and a complete excisional biopsy of the lesion was obtained by removing the tumor through the anterior chamber. Histopathological analysis of the specimen confirmed a diagnosis of peripheral, focal, nodular retinal gliosis. Postoperatively, visual function improved greatly, with no recurrence of the disease at 12 months' follow-up. Focal nodular retinal gliosis is a rare, non-neoplastic proliferation of retinal glial cells, with a vascular component. In our case, surgical treatment with pars plana vitrectomy facilitated accurate diagnosis and resulted in effective management of the retinal tumor and associated complications.

RESUMO

ABSTRACT: Repair of lower conjunctival fornix retraction is a great challenge for plastic surgeons in the aspects of orbital prosthesis retaining and cosmetic appearance. Hereby, a 25-year-old woman, suffering from lower conjunctival fornix retraction after the removal of retinoblastoma and radiotherapy, was undertaking the treatment with an improved reverse postauricular island flap for expansion of the lower conjunctival fornix, and volume augmentation of the anophthalmic socket in one stage. The flap was based on the parietal branch of the superficial temporal artery and its vascular architecture to the postauricular vascular system, and successfully transferred by passing through a subcutaneous tunnel. The satisfactory result indicated that the mentioned technique may be a good option in surgical rehabilitation of the stable depth of the lower conjunctival fornix, not only from the reliable blood supply and the suitable thickness of the flap but also from the less donor morbidity without an exposed unsightly scar. LEVEL OF EVIDENCE: Level V.

RESUMO

PURPOSE: Primary vitreoretinal lymphoma is the most common intraocular lymphoproliferative disorder. We evaluated the diagnostic yield of pars plana vitrectomy, specifically using modern high cut rate dual-cycle cutters, on in vitro cell viability and diagnostic yield. METHODS: Human Burkitt lymphoma cell line Namalwa at 2 x 10^5 cells/mL was aspirated by 25-gauge dual-blade guillotine-type vitrectomy at five speeds (500, 1,000, 4,000, 7,500, or 15,000 cuts per minute). Cell viability and diagnostic yield in each subtype group were determined using hemocytometry, viable cell count using Cell Counting Kit-8, and pathologist-guided manual count. RESULTS: No significant deviation in cell count was identified in any cut rate by ANOVA ( P = 0.61), and no trends in the number of viable cells were identified across cut rates (R 2 = 0.188, P = 0.47). Among histologic cell counts per cut-rate, neither linear regression (R = 0.531, P = 0.16) nor ANOVA ( P = 0.096) were statistically significant. CONCLUSION: There was no significant degradation in the number of viable cells with increasing cut speed. These results suggest that in contrast to previous findings using 20g or 23g vitrectomy for diagnostic vitrectomy, modern vitrectomy systems may be used at up to 15,000 cpm without compromising the viability of lymphoma cells.

RESUMO

Cell free DNA (cfDNA) and circulating tumor cell free DNA (ctDNA) from blood (plasma) are increasingly being used in oncology for diagnosis, monitoring response, identifying cancer causing mutations and detecting recurrences. Circulating tumor RB1 DNA (ctDNA) is found in the blood (plasma) of retinoblastoma patients at diagnosis before instituting treatment (naïve). We investigated ctDNA in naïve unilateral patients before enucleation and during enucleation (6 patients/ 8 mutations with specimens collected 5-40 minutes from severing the optic nerve) In our cohort, following transection the optic nerve, ctDNA RB1 VAF was measurably lower than pre-enucleation levels within five minutes, 50% less within 15 minutes and 90% less by 40 minutes.

RESUMO

AIM: To compare the risk and pattern of High-Risk Pathologic Features (HRPF) in retinoblastoma between primary and secondary enucleation. METHODS: A retrospective analysis of 121 eyes from 118 patients who underwent enucleation at the King Hussein Cancer Center (KHCC) Amman, Jordan, between November 2009 and January 2020. Demographic information, tumor stage, time from diagnosis-to-enucleation, results of pathology, metastasis, and mortality were retrieved. RESULTS: Patients in the secondary group (49/121 eyes, 40%) were considerably younger at diagnosis (p = 0.0014), had bilateral disease (p = 0.0001), and had less-progressed disease at presentation (p = 0.016) compared to the primary enucleation. Primarily enucleated eyes were more-likely to have massive choroidal invasion (p = 0.0315) and post-laminar optic nerve invasion (p = 0.027), in spite of the finding that the overall prevalence of HRPF was similar between the two groups (35.5 percent vs. 37.5 percent; p = 0.585). The likelihood of anterior chamber invasion, was considerably higher in secondary enucleated eyes (p = 0.013). We evaluated primary and secondary enucleation for each subgroup (D and E) of the International Intraocular Retinoblastoma Classification (IIRC) and found the prevalence of HRPF was comparable (p = 0.58, 1.0, respectively). The difference in time between diagnosis-to-enucleation in secondary enucleation did not predict HRPF (p = 0.50). There was no discernible difference between primary and secondary enucleated eyes in terms of metastasis or survival (p = 0.156 and 0.44, respectively). CONCLUSION: Systemic chemotherapy has the ability to reduce the extent of tumor expansion that has been pathologically identified. Primary and secondary enucleated eyes are comparable in low metastatic risk only when strict examination and management guidelines are followed.

RESUMO

BACKGROUND: Techniques used to suture the rectus muscle to the implant can influence the implant-related complications which is still a major problem following retinoblastoma enucleation. The goals of this work were to report the efficacy among patients with retinoblastoma who underwent enucleation followed by porous implant placement with the rectus muscles sutured with 5-0 polyester suture. METHODS: This was a retrospective study of consecutive patients with retinoblastoma who underwent primary enucleation and porous implant placement with the rectus muscles tagged and sutured to the implant with polyester 5-0 suture. All the patients were followed up for a minimum of 2 years. The main outcome measure was implant exposure. The secondary efficacy measures were other implant-related complications. RESULTS: Between May 2016 and December 2018, a total of 120 patients (120 eyes) underwent primary enucleation and porous implant placement were included. Postoperatively, 10/120 (8.3%) eyes developed exposure or conjunctival granuloma. Exposure was the most common postoperative complication (7/10, 70.0%). There were no cases of implant extrusion, migration, or infection. CONCLUSIONS: Polyester 5-0 sutures are successful in patients with retinoblastoma who underwent enucleation followed by porous implant placement. Complications are minimal. Polyester 5-0 sutures were not associated with unacceptable complications in this pediatric population.

RESUMO

BACKGROUND: Post-laminar optic nerve invasion (PLONI) is a high-risk factor for the metastasis of retinoblastoma (RB). Unlike conventional MRI, diffusion-weighted imaging (DWI) reflects histopathological features, and may aid the assessment of PLONI. PURPOSE: To determine the value of conventional MRI plus DWI in detecting PLONI in RB patients. STUDY TYPE: Retrospective. POPULATION: Eighty-three RB patients, including 28 with histopathologically proven PLONI and 55 without PLONI. FIELD STRENGTH/SEQUENCE: 3.0 T, precontrast axial T1-weighted and T2-weighted imaging, DWI, and postcontrast axial, coronal, and oblique-sagittal T1-weighted imaging. ASSESSMENT: PLONI was assessed using post-enucleation histology and preoperative MRI features (optic nerve signal intensity, enlargement, and enhancement on conventional MRI, and apparent diffusion coefficient [ADC] of the optic nerve on DWI) evaluated by three observers. STATISTICAL TESTS: MRI features suggesting the presence of PLONI were identified using univariable and multivariable analyses. Receiver operating characteristic (ROC) curve and area under the curve (AUC) were used to analyze diagnostic performance. RESULTS: Optic nerve enhancement and low ADC of the optic nerve were significant indicators of PLONI. ROC curve analysis showed that the AUC of the combination of these two features for detecting PLONI was 0.87 (95% confidence interval [CI]: 0.78-0.93). The diagnostic performance of this model was significantly superior to that of optic nerve enhancement alone (0.76, 95% CI: 0.65-0.85) and marginally superior to that of the ADC of the affected optic nerve (0.78, 95% CI: 0.68-0.87, P = 0.051). DATA CONCLUSION: Conventional MRI combined with DWI can improve the detection of PLONI in RB patients over conventional MRI alone. EVIDENCE LEVEL: 3 Technical Efficacy: Stage 2.

RESUMO

AIM: To evaluate if there is a difference in the clinical course of primary vitreoretinal lymphoma (PVRL) in vitrectomized versus non-vitrectomized eyes. METHODS: Observational multicenter retrospective case series of patients diagnosed with PVRL between 2007 and 2019, at three tertiary centers. The main outcomes were relapse rates, inflammatory parameters, and best-corrected visual acuities (BCVA). Statistical methods used were an adjusted generalized estimating equation model, and a proportional Cox model. RESULTS: Eighty patients (150 eyes) were followed for a median of 1.7 years. At presentation, there were no clinical differences between the groups. The relapse rate was 0.091/eye-year (EY) for vitrectomized eyes and 0.087/EY for non-vitrectomized eyes (p = .35). Vitrectomized eyes had better BCVA than non-vitrectomized eyes (p < .001). CONCLUSIONS: Vitrectomy had no effect on the relapse rate in eyes with PVRL. However, the decrease in vitreous cell and debris led to vitrectomized eyes having better visual acuity than non-vitrectomized eyes.

RESUMO

BACKGROUND: Von Hippel-Lindau syndrome is a rare autosomal dominantly inherited multisystemic oncologic syndrome, presenting predominantly with angiomatosis in embryologically similar neurologic tissue such as retina, cerebellum and adrenals. Retinal hemangioblastomas are the hallmark ophthalmic finding. In this case report, we describe the importance of timely diagnosis, thorough systemic examination and treatment of bilaterally asymmetrical retinal hemangioblastomas in a young adult male. CASE PRESENTATION: A 31-year-old male presented with painless diminution of vision in both eyes, associated with eyestrain and headache. Multiple asymmetric retinal lesions and dilated feeder vessels were noted on ophthalmoscopic examination and confirmed by fluorescein angiography to be retinal hemangioblastomas. Comprehensive systemic examination revealed cerebellar hemangioblastomas and multiple pancreatic and renal cysts. Treatment of retinal lesions was done by combination therapy of argon laser photocoagulation and cryopexy, which lead to a good visual outcome. Subsequently, neurosurgical resection of cerebellar hemangioblastoma proved to be lifesaving for the patient. CONCLUSION: RHBs are the earliest, easiest and the most frequently detected manifestation of VHL. Identification of ocular manifestations play a pivotal role in early diagnosis and timely intervention in VHL syndrome, thereby significantly reducing associated morbidity and mortality. Therefore, an ophthalmologist's role is crucial in the management of these potentially deadly tumours.

RESUMO

PURPOSE: To analyze the safety and efficacy of Pars Plana Vitrectomy (PPV) as a treatment for retinoblastoma patients and to evaluate the feasibility. METHODS AND PATIENTS: We collected 342 eyes who had PPV after systemic chemotherapy in our retrospective study, then analyze the 5-year overall survival and 5-year event-free survival rate, recurrence rate, and metastasis rate. The above data were used to evaluate the feasibility of PPV in the treatment of retinoblastoma. RESULTS: The mean value of follow-up time was 62.9 months from PPV. Of all 342 eyes, 18% eyes underwent enucleation of the eyeball. Excluding Non-PPV related deaths eyes, the 5-year overall survival rates and event-free survival were 95% and 80%; the tumor recurrence rate and metastasis rate were approximately 26% and 1.2%, respectively; the mortality was 3.9%. And the incidence of high-risk pathological factors of enucleated eyes after PPV was 32%. CONCLUSION: Our results suggest that Pars Plana Vitrectomy as a new approach to preserve the eyeball of RB children is feasible, especially for those patients who cannot be completely controlled by systemic chemotherapy or the tumors with vitreous seeds. Although the outcomes in our study are very optimistic, we also recommend an experienced eye surgeon to perform the operation and strictly control the indications for PPV surgery. And enough systemic chemotherapy is very important before and after surgery. LEVEL OF EVIDENCE: Treatment study (Retrospective comparative study), III.

RESUMO

Juxtapapillary retinal capillary hemangiomas are sight-threatening hamartomas located on or adjacent to the optic nerve. Nonsurgical approaches including laser photocoagulation and cryotherapy have been shown to be effective to reduce exudation in peripheral hemangiomas. However, in juxtapapillary hemangiomas, the functional outcomes are limited due to associated potential damage of the retinal nerve fiber layer. We present an 18-year-old female patient with von Hippel-Lindau (VHL) disease who presented with a juxtapapillary retinal capillary hemangioma associated with a tractional epiretinal membrane (ERM) and secondary macular hole. After vitrectomy-assisted excision of the lesion and inner limiting membrane (ILM) peeling around the macular hole, visual acuity and macular anatomy were recovered at 10 months of follow-up.

RESUMO

PURPOSE: To quantify the duration of anesthesia required for optimal management of retinoblastoma (Rb), stratified by clinical factors. METHODS: The medical records of Rb patients treated at Phoenix Children's Hospital between January 2011 and January 2022 were reviewed retrospectively. Demographic, tumor, and treatment data were collected. Anesthesia time was recorded for procedures requiring general anesthesia, including intra-arterial chemotherapy (IAC), enucleation, brainstem auditory evoked response testing (BAER), port placement, magnetic resonance imaging (MRI), and examination under anesthesia (EUA). Descriptive statistics were used to summarize patient and clinical characteristics. RESULTS: Total anesthesia time was 48,991 minutes for 610 procedures in 43 patients. The median follow-up time was 36 months (range, 12-114 months). Average anesthetic durations per exposure were 274, 152, 81.8, 62.5, 60.7, and 45 minutes for IAC, enucleation, BAER, port placement, MRI, and EUA, respectively. Patients with bilateral Rb underwent a median of 1,659 minutes of total anesthesia, compared with 397 minutes for those with unilateral disease. In patients with unilateral Rb, median total anesthesia time was 2,651, 1681, 312, 397 minutes for International Classification of Retinoblastoma grades B, C, D, and E tumors, respectively. Patients who received IAC as their primary treatment had the highest median anesthesia duration (2,100 minutes), followed by systemic chemo (654 minutes) and enucleation (289 minutes). CONCLUSIONS: Treatment of Rb requires prolonged and repeated exposure to general anesthesia. Future studies are required to determine the potential effects of these childhood anesthetic exposures.

RESUMO

BACKGROUND: Coats disease may cause diagnostic dilemma because of its variable clinical presentation that can be suspicious of retinoblastoma. Late sequelae of the disease are blinding with possible enucleation. We demonstrate the main histopathological findings of Coats enucleated eyes with literature review. METHODS: This was a retrospective study of all enucleated globes diagnosed as Coats disease over 30 years and were reviewed by two pathologists. The corresponding demographic data, clinical presentation, pre-operative clinical impression, and indication for enucleation were collected. Descriptive analysis of our own series data was performed. Our findings were then correlated to published data that were collected from 1983 to 2021 from the PUBMED database in English-written language. Shields classification was used as an inclusion criterion for the published reports to be analyzed. RESULTS: We had seven enucleated globes with Coats disease. Mean age at presentation was 3.2 years (range 3 months to 9 years). Male predominance was observed in 6 and all cases were unilateral. Strabismus was the most common initial presentation (57%, n = 4), followed by leukocoria (43%, n = 3). Indication for enucleation was mostly suspected retinoblastoma (57%, n = 4). Four eyes were classified as stage 4, and 2 had advanced stage 5 changes. Histopathologically, subretinal fluid with lipid-laden macrophages was seen in all cases, the anterior chamber was shallow in 5/7 with angle neovascularization in 2/7. Telangiectatic vessels were clearly observed in 4/7. CONCLUSION: Coats disease is a potentially visually disabling disease that is mostly unilateral in 95%, has male predominance of 81%, and wide age range with a mean of 17 years. In Saudi Arabia, the disease seems to present at younger age, tends to be more advanced, and may be indistinguishable from retinoblastoma at the time of diagnosis. Shields staging of Coats is highly recommended to be followed clinically to unify the pathways for treatment and to correlate the concluded outcomes.
