RESUMEN
OBJECTIVES: To retrospectively investigate clinical characterization and the long-term postoperative outcomes of retinoblastoma (RB) patients receiving enucleation with primary orbital implantation in early infancy (0-6 months old). METHODS: The clinical and follow-up data of 42 RB patients receiving enucleation with primary orbital implantation in early infancy at Beijing Tongren Hospital from December 2009 to January 2020 were analysed. The average follow-up time was 83 months. The patient group included 24 males and 18 females, 30 unilateral and 12 bilateral cases. A total of 44 eyes with 10 in stage D and 34 in stage E underwent 40 unilateral and 2 bilateral surgeries. 17 RB eyes received hydrogel and 27 RB eyes received hydroxyapatite implants. This study was performed by following the guideline of STROBE. RESULTS: Enucleation combined with primary orbital implantation promoted survival and was safe with few and minor complications such as increased secretion, upper eyelid ptosis, and sunken eye sockets which were not affected by stages, lateralities, or implant materials. 55-80% RB patients exhibited satisfactory appearance and obvious or moderate motility of orbital implants according to the evaluation by doctors and family members. Family members were likely more optimistic about the appearance and more pessimistic about motility of the orbital implantation than doctors did.The quality of life was high as indicated by PedsQL3.0 or PedsQL4.0 scores ( ⧠90 for > 75% patients). It was not affected by the stages, laterality, and implant materials, nor affected by the appearance and motility of the implants. CONCLUSIONS: The outcomes of the combination of enucleation and primary orbital implantation for pertinent RB patients in early infancy are generally satisfactory with few and minor complications, high safety, appearance, and overall quality of life. Enucleation combined with primary orbital implantation in early infancy benefits pertinent RB patients in appearance, survival, and quality of life.

BACKGROUND: Retinoblastoma (RB) is an intraocular malignant tumor detected in early childhood with variable global impact. Histopathological classification of the tumor in enucleated globes with RB is the key for the decision of adjuvant chemotherapy use. We aim to validate the use of adjuvant chemotherapy in cases with combined pre-laminar/intralaminar optic nerve (ON) invasion and focal choroidal invasion according to the American Joint Committee on Cancer (AJCC) 8th classification. METHODS: This is a retrospective study conducted at King Abdulaziz University Hospital (KAUH) and King Khalid Eye Specialist Hospital (KKESH) in Riyadh, Saudi Arabia of all RB cases who underwent enucleation over 22 years (2000 to 2021). The histopathological findings were reviewed to identify the enucleated globes classified as pT2a tumors, as an inclusion criterion. Basic demographic and clinical data were collected via chart review Simple descriptive and basic statistical analysis of the data was used where applicable. RESULTS: Thirty-one patients who had an enucleated globe with RB that fit into the above classification were included. Sixteen were males and 15 were females. The median age was 14 months (IQR = 14 months). Most of the patients (93.5%) had no family history of RB. The commonest presentation was leukocoria in 87.1% followed by squint in 32.3%. Fourteen patients (45.2%) were treated by enucleation alone while 17 patients (54.8%) received adjuvant chemotherapy. Out of these, 7 patients had unilateral RB and the remaining 10 patients had bilateral RB. None of our patients developed recurrence or metastatic disease irrespective of the indication for adjuvant chemotherapy use after a maximum period of follow up reaching 17.84 years and a median of 10.6 years (IQR = 5.92). CONCLUSIONS: In patients with 8th AJCC histopathological classification of pT2a, chemotherapy following enucleation might not be justified. The outcome in our untreated group of patients did not differ from the treated group with the absence of metastasis after a relatively long period of follow up with a median exceeding 10 years in both groups. Therefore, the risk and benefit of post enucleation adjuvant chemotherapy in the treatment of unilateral RB should be carefully decided and discussed with the primary caregivers taking into consideration the most recent evidence and recommendations in the literature.

PURPOSE: To describe amniotic membrane augmentation for enucleation after chemotherapy in retinoblastoma. METHODS: This was a retrospective study of patients with retinoblastoma who underwent enucleation. The study also evaluated the utility of amniotic membrane grafting in enucleation after chemotherapy in eyes with retinoblastoma. RESULTS: In this study, 110 eyes of 107 patients were analyzed, and 49 patients had previous systemic chemotherapy, 13 eyes had previous intra-arterial chemotherapy, and 7 eyes had external beam radiation. Amniotic graft was used in 8 eyes (5 following IAC, 2 following systemic chemotherapy, and 1 after both). After IAC, 3 of 7 eyes without amniotic graft had implant exposure compared to 0 of 6 eyes with amniotic graft (P = .05). Pathological examination of the conjunctiva after intra-arterial chemotherapy showed goblet cell hypoplasia that hinders wound healing. CONCLUSIONS: Amniotic membrane augmentation improves wound integrity in patients with retinoblastoma, especially following intra-arterial chemotherapy.

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.

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.

BACKGROUND AND OBJECTIVE: Monitoring the response of retinoblastoma to globe-salvaging therapies is based on subjective assessments of changes determined by fundoscopy, ultrasound, and optical coherence tomography. Advances in organ-preserving therapies have increased the need for objective, quantitative estimates of tumor response to treatment. Primary tumor volume is a metric that can be objectively determined as a surrogate measure of treatment response. PATIENTS AND METHODS: We evaluated the correlation of objective, quantitative estimates of tumor volume made with two-dimensional (2D) and three-dimensional (3D) ultrasound with gold standard pathological tumor volumes derived by analysis of enucleation specimens. RESULTS: Twelve eyes in 12 patients undergoing primary enucleation were evaluated by 2D and 3D ultrasound during ophthalmic examination under anesthesia prior to enucleation. 2D- and 3D-ultra-sound measurements of tumor volume were both strongly correlated with pathological estimates of tumor volume (r = 0.69, P = 0.018; and r = 0.66, P = 0.027, respectively). CONCLUSIONS: 2D- and 3D-ultrasound measurements of retinoblastoma primary tumor volume are highly correlated with pathological estimates. 3D measurements are easy to perform with volumetric probes and consider the irregular morphology of the tumor. Further study should be undertaken to evaluate the performance of these metrics as surrogate markers of tumor response to treatment. [Ophthalmic Surg Lasers Imaging Retina 2024;55:136-140.].

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.

PURPOSE: To explore whether varying degrees of vitreous haemorrhage (VH) and calcification act as risk factors for enucleation in patients with advanced retinoblastoma (RB). METHODS: Advanced RB was defined by the international classification of RB (Philadelphia version). Basic information for retinoblastoma patients diagnosed as groups D and E in our hospital between January 2017 and June 2022 was reviewed by logistics regression models. Additionally, a correlation analysis was performed, excluding variables with a VIF (variance inflation factor) >10 from the multivariate analysis. RESULTS: A total of 223 eyes diagnosed with RB were included in assessing VH and calcification; of these, 101 (45.3%) eyes experienced VH, and 182 (76.2%) eyes were found to have calcification within the tumour through computed tomography (CT) or B-scan ultrasonography. Ninety-two eyes (41.3%) were enucleated, of which 67 (72.8%) had VH and 68 (73.9%) calcification, both of which were significantly relevant to enucleation (p < 0.001*). Other clinical risk factors, such as corneal edema, anterior chamber haemorrhage, high intraocular pressure during treatment and iris neovascularization, correlated significantly with enucleation (p < 0.001*). Multivariate analysis included IIRC (intraocular international retinoblastoma classification), VH, calcification and high intraocular pressure during treatment as independent risk factors for enucleation. CONCLUSIONS: Despite identifying different potential risk factors for RB, there remains significant controversy concerning which patients require enucleation, and the degree of VH varies. Such eyes need to be evaluated carefully, and management with appropriate adjuvant therapy may improve the outcome of these patients.

PURPOSE: To evaluate the complications of anophthalmic socket in retinoblastoma patients at a tertiary centre in Malaysia. DESIGN: Retrospective study. METHODS: Patients who underwent enucleation for retinoblastoma were reviewed from 2004-2020. Details were recorded, including demographics, diagnosis, surgical techniques, implant types, additional therapies, and complications. RESULTS: Of 250 patients with retinoblastoma managed over the period, the anophthalmic sockets of 160 eyes who underwent enucleation were analysed. The mean age at enucleation was 2.03 years (26 days to 9.18 years). The follow-up periods after enucleation range from 5 days to 16.83 years. Porous polyethylene (Medpor) implants were used in 135 patients (84.4%), as were Bioceramic in 9, glass balls in 7, acrylic in 7, dermis fat grafts in 1, and silicone implants (Aurosphere) in 1. The overall complications in our study were 28.8%. Complications seen in the study included implant exposure (12.5%), shallow inferior fornix (10.6%), granuloma formation (3.1%), discharge (2.5%), implant migration (1.9%), ptosis (0.6%), and orbital dystopia (0.6%). Implant exposure is solely found in Medpor, more common in those with donor sclera caps, and exposure times range from 28 days to 11.42 years. The suturing of the Tenon and conjunctiva in separate layers significantly reduced the rate of implant exposure. Six out of seven radiation patients had shallow inferior fornixes. CONCLUSIONS: Long-term post-enucleation complications were not uncommon. Luckily, most had good outcomes, with a few needing surgical intervention. Meticulous suturing technique on the Tenon and conjunctival layer is essential to prevent implant exposure.

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.

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.

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.

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.

PURPOSE: To determine the direct medical costs and cost-effectiveness of globe salvage compared with primary enucleation in patients with advanced retinoblastoma. METHODS: Patients with International Classification of Retinoblastoma groups C-E retinoblastoma at a single institution from 2001 to 2021 were categorized into two groups: primary enucleation and globe salvage. Hospital visits and treatments were compared to determine differences in care utilization. Costs per encounter were derived from billing data and multiplied by number of encounters to determine total costs in the first year of treatment. Groups were stratified by unilateral or bilateral retinoblastoma, and visual acuity-based utility values were used to compare quality-adjusted life years to determine cost-effectiveness. RESULTS: Of 74 group C-E eyes of 70 patients, 55 eyes underwent primary enucleation and 19 eyes underwent globe salvage, 12 of which ultimately underwent secondary enucleation. Patients who underwent globe salvage had higher usage of systemic chemotherapy (P = 0.001), more examinations under anesthesia (P < 0.001), fewer outpatient visits (P = 0.03), and a higher total cost of care (301,151 vs 104,764 USD [P < 0.001]) in the first year of treatment compared with the primary enucleation group. At an average life expectancy of 76 years, the incremental cost-effectiveness ratio was 118,347 USD per QALY in unilateral retinoblastoma and 32,987 USD per QALY in bilateral retinoblastoma, meeting the <150,000 USD/QALY threshold of cost-effectiveness. CONCLUSIONS: Incurring additional costs may save the eye in advanced retinoblastoma, but the possibility of secondary enucleation should be disclosed for informed decision making. Despite this risk, globe salvage was cost-effective in unilateral and bilateral retinoblastoma.

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.

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.

PURPOSE: To evaluate the correlation between clinical presentations, radiological findings and high risk histopathological features of primary enucleated eyes in patients with advanced retinoblastoma at a tertiary child hospital in Thailand. MATERIALS AND METHODS: We retrospectively reviewed the medical records of patients who were treated with primary enucleation of tumor eyes between 2015-2020. Demographic data, radiological assessment, and histopathological findings were collected. The association between clinical presentations and high-risk histopathological features in the primary enucleated eyes were evaluated. The radiological findings, which showed characteristic of high risk features, were compared with the histopathological findings. RESULTS: Thirty-three enucleated eyes were enrolled in this study. The mean age at diagnosis was 23.12 months. Most patients had unilateral group E retinoblastoma, with no difference in sex and laterality of the eye. Leukocoria was the most common presentation, followed by proptosis and uveitis. Older age at presentation were statistically associated with post laminar cribrosa optic nerve invasion (P-value 0.0027) and high-risk histopathological features in enucleated eyes (P-value 0.0032). Clinical presentations with proptosis were statistically associated with post laminar cribrosa optic nerve invasion, while leukocoria and uveitis were statistically associated with anterior segment invasion. Unifocal intraocular mass with necrosis was the most common histopathological finding. High-risk features were found in 45% of primary enucleated eye. The sensitivity and specificity of magnetic resonance imaging (MRI) for detected optic nerve invasion in retinoblastoma patients were 75% and 54%, respectively. CONCLUSION: Patients with unilateral retinoblastoma who presented with older age related to high-risk features after enucleation. Ophthalmic examination with slitlamp is the best way for detection of anterior segment invasion. Choroidal invasion was unable to predict with clinical presentation. MRI was the better imaging for detection of post laminar cribrosa optic nerve invasion.

Background: Retinoblastoma is a rare form of pediatric eye cancer for which enucleation is a common treatment modality. There is an increasing focus upon the impact of enucleation on children and families. This study aimed to explore the experiences of children and their families following enucleation to consider the barriers that may be encountered when adjusting to living with an artificial eye and identifying the support services and strategies used to address these barriers. Methods: Using a descriptive qualitative approach, interviews were conducted with 12 parents and seven children and thematic analysis was used to identify four themes representing the perspective of parents and children. Results: Parent themes identified were (a) entry into the world of retinoblastoma; (b) the importance of specialist support; (c) a family learning to cope; and (d) navigating school. The perspectives of children were (a) the importance of preparation and play; (b) positive reinforcement and hospital support; (c) support and openness at home; and (d) the importance of good school planning. Two overarching themes related to parent and child adaptation were also identified. Discussion: The study findings reveal that the process of adapting to living with an artificial eye extended to influencing decisions around parenting, learning to advocate for their child, and supporting children through school and peer relationships. For children, the importance of ongoing support and information was vital to enhance understanding, adaptation, and development of independence. Overall, the study suggests that children and families undergoing enucleation need continuing, individualized, and specialist support.
