Indocyanine green-enhanced transpupillary thermotherapy for juxtapapillary retinal capillary hemangioblastoma.

PURPOSE: To study the clinical presentation and treatment outcomes of indocyanine green-enhanced transpupillary thermotherapy (ICG-TTT) for treatment-naïve juxtapapillary retinal capillary hemangioblastoma (JRCH). METHODS: A prospective interventional case series. The technique involved ICG dye infusion 45 seconds prior to application of TTT. The main study outcomes were local tumor control, resolution of subretinal fluid (SRF), and improvement in best-corrected visual acuity (BCVA). RESULTS: Eight eyes of seven patients (5 males and 2 females) were included. The mean age was 26 years (range: 5-56 years). Systemic evaluation revealed von-Hippel Lindau (VHL) disease in five patients. The most common location was the temporal aspect of the optic disc (5 eyes). The mean basal diameter was 2.9 mm (range: 1-8 mm), and tumor thickness was 1.4 mm (range: 1-4 mm). All eight eyes were treated with multiple sessions of ICG-TTT (mean: 3 sessions). Six eyes received adjuvant intravitreal injection of dexamethasone implant (4 eyes) and/or bevacizumab (4 eyes). Post treatment, six eyes (75%) had tumor regression with reduction of SRF. One eye had a partial response with persisting SRF, and one eye showed poor response to TTT for which external beam radiotherapy was performed. At the last follow-up (median: 11 months; range: 6-29 months), the BCVA remained stable in seven eyes and improved in one eye (hand motion to 20/40). CONCLUSION: Multiple ICG-TTT sessions can be considered as an alternative treatment option for JRCH with effective local tumor control and SRF resolution.

Retinoblastoma: present scenario and future challenges.

With an average incidence of 1 in every 18,000 live births, retinoblastoma is a rare type of intraocular tumour found to affect patients during their early childhood. It is curable if diagnosed at earlier stages but can become life-threateningly malignant if not treated timely. With no racial or gender predisposition, or even environmental factors known to have been involved in the incidence of the disease, retinoblastoma is often considered a clinical success story in pediatric oncology. The survival rate in highly developed countries is higher than 95% and they have achieved this because of the advancement in the development of diagnostics and treatment techniques. This includes developing the already existing techniques like chemotherapy and embarking on new strategies like enucleation, thermotherapy, cryotherapy, etc. Early diagnosis, studies on the etiopathogenesis and genetics of the disease are the need of the hour for improving the survival rates. According to the Knudson hypothesis, also known as the two hit hypothesis, two hits on the retinoblastoma susceptibility (RB) gene is often considered as the initiating event in the development of the disease. Studies on the molecular basis of the disease have also led to deciphering the downstream events and thus in the discovery of biomarkers and related targeted therapies. Furthermore, improvements in molecular biology techniques enhanced the development of efficient methods for early diagnosis, genetic counseling, and prevention of the disease. In this review, we discuss the genetic and molecular features of retinoblastoma with a special emphasis on the mutation leading to the dysregulation of key signaling pathways involved in cell proliferation, DNA repair, and cellular plasticity. Also, we describe the classification, clinical and epidemiological relevance of the disease, with an emphasis on both the traditional and innovative treatments to tackle retinoblastoma. Video Abstract.

Caring for a child with retinoblastoma: Experience of Ethiopian parents.

OBJECTIVE: This study explored the lived experience of parents of children with retinoblastoma. DESIGN AND METHOD: A phenomenological qualitative study design was used, and a purposive sampling technique to recruit parents of children with retinoblastoma. Semi-structured interviews were conducted to document the lived experience of participants, who were asked to narrate their experiences caring for a child with retinoblastoma, thinking back to the day they learned about their child's condition, as well as their thoughts about the future. The interviews were conducted in Amharic and Oromo language, and audio recordings were transcribed and translated to English. Data were analyzed using thematic analysis. RESULTS: Thirteen parents (seven mothers, six fathers) participated in the study. Collectively, the children of the participants represented all the stages of the retinoblastoma journey (i.e., diagnosis, treatment, remission, and recurrence). Five major themes emerged from the thematic data analysis: (a) reactions when learning the child's condition; (b) receiving health care; (c) costs of caregiving; (d) support; and (e) uncertainties. CONCLUSION: The lived experiences of parents of children with retinoblastoma revealed a significant mental health and psychosocial burden. The sources of mental distress were found to be complex and varied. Holistic care for retinoblastoma should include programs that address the biopsychosocial needs of caregivers.

Ruptured retinoblastoma: management in a rare case scenario.

A preschool child presented with white reflex in left eye since 2 months. Examination under anaesthesia revealed left eye retinoblastoma group D as per international classification of retinoblastoma. In collaboration with medical oncologist, systemic chemotherapy was started. After two cycles of systemic chemotherapy, tumour ruptured into the vitreous cavity suspending the tumour cells in the vitreous jelly. After a combination of systemic and intravitreal chemotherapy with adjuvant transpupillary thermotherapy of the residual retinal tumour, retinoblastoma regressed completely with corresponding flat scar.

Efficacy and safety of current treatment options for peripheral retinal haemangioblastomas: a systematic review.

IMPORTANCE: Approximately twenty per cent of Von Hippel-Lindau patients with retinal haemangioblastomas (RH) suffer from visual impairment. Various treatment options are available for peripheral RH. However, management of peripheral RH is complex due to multifocality and bilaterality. OBJECTIVE: To summarize published evidence on efficacy and safety of different interventions for peripheral RH and to provide treatment recommendations for specialists. EVIDENCE REVIEW: Comprehensive searches were performed using Medline, Embase, Web of Science and Google Scholar database on 4 March 2020. English publications that described outcomes related to efficacy or complications in at least two patients with peripheral RH were included. Efficacy and safety were estimated by complete tumour eradication rate, pretherapeutic and treatment-related complication rate. Odds ratios (OR) with 95% confidence intervals (CI) were calculated to calculate the risk estimate of complications between treatment options. FINDINGS: Twenty-seven articles were included in this review describing nine different treatment options for peripheral RH: laser photocoagulation (n = 230), cryotherapy (n = 50), plaque radiotherapy (n = 27), vitreoretinal surgery (n = 88), photodynamic therapy (PDT; n = 14), transpupillary thermotherapy (TTT; n = 10), external beam radiotherapy (n = 3), systemic treatment (n = 7) and intravitreal anti-VEGF (n = 2). Complete tumour eradication was achieved in 86.7% (95% CI: 83.5-89.9%) of all eyes. For the different treatments, this was after laser photocoagulation 89.9% (86.1-93.7%), cryotherapy 70.2% (57.0-83.4%), plaque radiotherapy 96.3% (89.1-100.0%), vitreoretinal surgery (100.0%), PDT 64.3% (38.3-90.3%) and TTT 80.0% (53.8-100.0%). No complete tumour eradication was achieved after systemic therapy, external beam radiotherapy or intravitreal anti-VEGF. Photodynamic therapy and vitreoretinal surgery showed the highest complication rate after treatment compared to the other treatments (OR 10.5 [95% CI: 2.9-38.4]) and (OR 5.9 [95% CI: 3.4-9.9]), respectively. Cases that had pretherapeutic complications showed a higher treatment-related complication rate (OR 14.8 [95% CI: 7.3-30.0]) than cases without complications before treatment. CONCLUSIONS AND RELEVANCE: These findings suggest that laser photocoagulation is the safest and most effective treatment method for peripheral RH up to 1.5 mm in diameter. Vitreoretinal surgery has the highest success rate for complete tumour eradication and may be the most suitable treatment option in the presence of pretherapeutic complications and for larger tumours.

Selective Ophthalmic Artery Chemotherapy with Melphalan in the Management of Unilateral Retinoblastoma: A Prospective Study.

PURPOSE: To determine prospectively the efficacy and to assess potential side effects of melphalan selective ophthalmic artery chemotherapy (SOAC) as first-line treatment for unilateral retinoblastoma. DESIGN: Phase 2 nonrandomized, prospective study. PARTICIPANTS: Patients with unilateral retinoblastoma group B, C, or D of the International Classification for Intraocular Retinoblastoma (IRC). Group D eyes with massive vitreous seeding were not eligible. METHODS: Melphalan SOAC associated with diode laser thermotherapy, cryotherapy, or both at 4-week intervals (3-6 cycles). For persistent vitreous seeding, intravitreal melphalan chemotherapy also was used. MAIN OUTCOME MEASURES: The primary outcome was globe preservation rate. Secondary outcomes were tumor relapse rate, occurrence of ocular or systemic adverse events, and measurement of the dose area product (DAP). RESULTS: Between 2012 and 2017, 39 patients (39 eyes) with unilateral retinoblastoma were included prospectively. Three included patients did not receive SOAC (2 catheterization failures and 1 case of viral syndrome) and were considered failures. At diagnosis, IRC groups for the 36 treated patients were: B, n = 4 (11%); C, n = 13 (36%); and D, n = 19 (53%); median age was 21.5 months (range, 3.2-61.6 months). Median number of SOAC cycles was 3.9 (range, 1-6 cycles), and median melphalan dose was 4.9 mg/procedure. The median DAP was 1.24 Gy.cm2/procedure. Median follow-up was 63 months (range, 34-93 months). SOAC was associated with local treatments for 31 patients (86%): diode laser thermotherapy for all of them and cryotherapy or intravitreal chemotherapy for 10 (32%) and 9 patients (25%), respectively. SOAC treatment was interrupted in 5 patients because of severe ophthalmic (ptosis, n = 2; retinal ischemia, n = 2) or systemic (hypotension, n = 1) adverse events. At the cutoff date analysis, all patients were alive without metastasis. The 18-month eye preservation rate was 80% (range, 68.6%-94.6%). After a follow-up of at least 30 months, the ocular preservation rate was 69% (n = 24 preservations). CONCLUSIONS: This first prospective trial demonstrated that SOAC with melphalan alone as first-line treatment for retinoblastoma is efficient and well tolerated with no metastatic events, although ocular ischemic complications were observed.

Delayed metastasis in patients with intraocular retinoblastoma: A review of three cases.

PURPOSE: To discuss the clinical presentation, management, and outcome of delayed metastasis in retinoblastoma (RB). METHODS: Retrospective case series of three patients. RESULTS: Mean age at diagnosis of RB was 29 months (median, 28 months; range, 11-48 months). All were males with non-familial bilateral intraocular RB. Primary treatment for RB included intravenous chemotherapy in all three cases. Secondary treatment included transpupillary thermotherapy/cryotherapy (n = 6 eyes), periocular chemotherapy (n = 2 eyes), intravitreal chemotherapy (n = 1 eye), intra-arterial chemotherapy (n = 1 eye), external beam radiotherapy (EBRT; n = 2 eyes), and enucleation (n = 2 eyes). Primary tumor regression was achieved in all cases and remained status quo at the time of diagnosis of distant metastasis. Two patients developed bone metastasis (ulna; tibia) and one developed soft tissue metastasis (temporal fossa) over a mean follow-up period of 6 years (median, 7 years; range, 5-8 years) from diagnosis of RB. Mean age of detection of metastatic disease was 8 years (median, 8 years; range, 7-9 years). All the lesions were solitary and the diagnosis of metastatic retinoblastoma was confirmed by tissue biopsy. Metastatic disease was treated with surgical excision (n = 1), chemotherapy (n = 2), and EBRT (n = 2). All patients are alive, with two patients free of disease over a mean follow-up period of 23 months (median, 23 months; range, 12-33 months); and 1 in remission 7 months after completion of EBRT. CONCLUSION: Long-term follow-up of RB cases is mandatory. In spite of intraocular tumor regression, metastasis can still occur many years after treatment of RB.

Modern treatment of retinoblastoma: A 2020 review.

Retinoblastoma management remains complex, requiring individualized treatment based on International Classification of Retinoblastoma (ICRB) staging, germline mutation status, family psychosocial factors and cultural beliefs, and available institutional resources. For this 2020 retinoblastoma review, PubMed was searched for articles dated as early as 1931, with an emphasis on articles from 1990 to the present day, using keywords of retinoblastoma, chemotherapy, intravenous chemotherapy, chemoreduction, intra-arterial chemotherapy, ophthalmic artery chemosurgery, intravitreal chemotherapy, intracameral chemotherapy, cryotherapy, transpupillary thermotherapy, laser, radiation, external beam radiotherapy, plaque radiotherapy, brachytherapy, and enucleation. We discuss current treatment modalities as used in the year 2020, including intravenous chemotherapy (IVC), intra-arterial chemotherapy (IAC), intravitreal chemotherapy (IvitC), intracameral chemotherapy (IcamC), consolidation therapies (cryotherapy and transpupillary thermotherapy [TTT]), radiation-based therapies (external beam radiotherapy [EBRT] and plaque radiotherapy), and enucleation. Additionally, we present a consensus treatment algorithm based on the agreement of three North American retinoblastoma treatment centers, and encourage further collaboration amongst the world's most expert retinoblastoma treatment centers in order to develop consensus management plans and continue advancement in the identification and treatment of this childhood cancer.

A 20-year audit of retinoblastoma treatment outcomes.

OBJECTIVES: To evaluate the long-term treatment outcomes in intraocular retinoblastoma (RB) including the associated factors for eventual treatment with external beam radiotherapy (EBRT) and enucleation as well as to analyse the risk factors for metastasis and death in extraocular RB. METHODS: Retrospective analysis of 390 eyes from 256 (89.8%) intraocular RB and 29 (10.2%) extraocular RB cases diagnosed and treated between October 1998 and May 2018 at one of the largest tertiary care centers in Turkey. RESULTS: Of 351 intraocular RB eyes, 53.3% had group D/E disease at presentation. 75 (21.4%) of 351 eyes underwent primary enucleation. Of the remaining 276 eyes undergoing eye-conserving treatments, 201 (72.8%) were salvaged. Most of these eyes were treated using intravenous chemotherapy and/or focal treatments [transpupillary thermotherapy (TTT) and cryotherapy] initially. EBRT was eventually required in 48 (17.4%) eyes and secondary enucleation in 75 (27.2%) eyes. At mean follow-ups of 76.7 and 39.7 months for intraocular and extraocular RB cohorts, respectively, 180 (46.2%) eyes underwent primary/secondary enucleation and exenteration. Overall, 13 cases developed metastasis and 9 died. Two patients with trilateral RB also expired. Multivariable risk factors for enucleation were the presence of vitreous seeds (p < 0.001), absence of EBRT administration (p = 0.033), 5-9 TTT applications compared with no TTT (p = 0.031), and each 1 mm increase in tumour base diameter (p < 0.001). Univariate factors predictive of metastasis were the presence of extraocular RB detected by imaging methods (p < 0.001) and extrascleral/optic nerve cut end involvement at histopathological examination (p < 0.001). CONCLUSIONS: In our series, 72.8% of the intraocular RB eyes undergoing eye-conserving treatments were saved. The globe salvage rate for all intraocular and extraocular RB eyes was 53.8% and the overall survival rate was 96.1%.

Selective nano-thermal therapy of human retinoblastoma in retinal laser surgery.

In this research, an experimental validated predictive finite element model of a cancerous human eye is developed to investigate how the tumor cells in retinoblastoma can be selectively damaged in the course of laser irradiation. In the computational modeling, the tumor is assumed to be in the initial growth stages and located in the macular zone. The statistical calculations testify that an 8.5% improvement in our estimation of the experimental temperature inside the normal human eye compared to those provided by the previous model has been achieved. Under the surgical conditions, the at-risk regions are determined, and the thermal responses of the tissue to various intrinsic and operating factors are obtained and discussed. Our findings indicate that, in the same amount of exposure time, introducing biodegradable nanoparticles in a concentration of 0.2 into the tumor tissue can increase the lethal zone area by 51 percent, and could plays an effective role in surviving of corneal injury.

Outcomes of neonatal retinoblastoma in pre-chemotherapy and chemotherapy eras.

Purpose: To quantify outcomes for neonatal retinoblastoma patients treated during the pre-chemotherapy (1980-1994) and chemotherapy (1995-2018) eras. Methods: Retrospective review of retinoblastoma patients diagnosed within the first 28 days of life between 1/1/1980 and 11/30/2018. Student's t-test, Chi-square, and Fisher's exact test were performed to compare treatments and outcomes by era. Results: There were 68 patients with neonatal retinoblastoma (12% unilateral and 88% bilateral). According to era (pre-chemotherapy vs. chemotherapy), the number of treated patients was 26 (38%) vs. 42 (62%). Primary treatment was external beam radiotherapy (50% vs. 1%,P < 0.001), plaque radiotherapy (17% vs. 0%,P < 0.001), focal treatment (transpupillary thermotherapy or cryotherapy) only (21% vs. 14%,P= 0.33), intravenous chemotherapy (0% vs. 81%,P < 0.001), enucleation (10% vs. 4%,P= 0.26), or exenteration (2% vs. 0%,P= 0.37). Outcomes included tumor control (79% vs. 94%,P= 0.02), globe salvage (75% vs. 91%,P= 0.02), final gross visual acuity for salvaged eyes 20/200 or better (66% vs. 89%,P < 0.01), and death (19% vs. 0%,P < 0.01). Conclusion: Chemotherapy advancements for neonatal retinoblastoma have improved tumor control, globe salvage, visual acuity, and patient survival.

Conservative treatment of diffuse infiltrating retinoblastoma: optical coherence tomography-assisted diagnosis and follow-up in three consecutive cases.

BACKGROUND/AIMS: To report conservative therapy in diffuse infiltrating retinoblastoma (DIR) and describe specific optic coherence tomography (OCT) features of the tumour. METHODS: Retrospective review of all DIR cases treated conservatively between 1998 and 2012. RESULTS: Three patients (three eyes) were included, cases 1 and 3 with previous enucleation of the contralateral eye and case 2 with unilateral retinoblastoma referred after prior pars plana vitrectomy with silicone oil. Mean age at diagnosis was 7 years (range 14 months-14 years). Globe and vision preservation (Snellen visual acuity of 12.5/10) was achieved in case 3 with a recurrence-free follow-up of 33 months after first-line thermotherapy followed by salvage intra-arterial chemotherapy (IAC) plus focal treatments. Cases 1 and 2 were enucleated for progressive disease, case 1 after first-line intravenous chemotherapy (IVC) consolidated by focal therapies and salvage treatments given over 8 years of partial remission and case 2 after IAC, brachytherapy and intracameral chemotherapy. Neither showed any high-risk histopathological features, and no adjuvant chemotherapy was necessary. Both patients are alive without metastasis (mean follow-up of >10 years). Pathognomonic features of the tumour were revealed by OCT in all cases, showing infiltration of the ganglion cell layer and horizontal growth over the inner plexiform layer. Complete restoration of the retinal microanatomy was documented after retraction of the tumour following IVC in case 2 and IAC in case 3. CONCLUSION: This is the first report of successful conservative management in DIR. OCT enabled diagnosis, delimitation of the tumour margins and monitoring of the treatment response in this context.

Hand-held Optical Coherence Tomography Monitoring of Submillimeter Retinoblastoma Treated with Indocyanine Green-enhanced Transpupillary Therapy.

Over recent years, hand-held optical coherence tomography (HH-OCT) has become critical for retinoblastoma diagnosis and management. We report precise HH-OCT findings in a case of sub-millimeter retinoblastoma treated with foveal-sparing indocyanine green-enhanced transpupillary thermotherapy (ICG-TTT). A 2-month-old Caucasian female with bilateral Group B retinoblastoma showed two recurrent macular tumors in the right eye, demonstrating 88 µm and 37 µm of growth to 344 µm and 413 µm in thickness, respectively, on HH-OCT. Each was treated with additional intravenous chemotherapy and foveal-sparing ICG-TTT. Tumor regression to 154 µm and 224 µm was documented on HH-OCT and maintained on follow-up. HH-OCT is vital in confirming clinical findings and influencing management decisions in retinoblastoma. In this case, HH-OCT precisely documented submillimeter retinoblastoma recurrence and treatment response.

Strabismus in retinoblastoma survivors with long-term follow-up.

PURPOSE: To report the long-term strabismus rate in salvaged retinoblastoma (Rb) patients and investigate possible risk factors leading to strabismus. METHODS: The medical records of patients with Rb presenting at a single institution over a 9-year period were reviewed retrospectively with regard to ocular alignment outcomes after long-term follow-up. RESULTS: A total of 64 eyes of 42 patients (22 bilateral cases [52%]) were included, presenting with International Intraocular Retinoblastoma Classification (IIRC) in the worse eye as follows: group A (n = 1), B (n = 16), C (n = 12), D (n = 11), no Rb (n = 2). Fifteen patients (36%) were initially referred because of family history of Rb. Mean age at presentation was 8.2 months (range, 0.3-58.3 months). Overall treatments included intravenous chemotherapy (62 eyes), intraophthalmic artery chemotherapy (10 eyes), brachytherapy (11 eyes), transpupillary thermotherapy (22 eyes), cryotherapy (47 eyes), and external beam radiotherapy (4 eyes). At final follow-up (mean, 93.7 months), 69% of patients had strabismus, with exotropia being the most common type (n = 18), followed by esotropia (n = 8), and alternate exotropia/esotropia (n = 3). On univariate analysis, the worse eye group IIRC and cTNMH, sporadic cases, strabismus, and foveal tumor at presentation were found to be significantly associated with strabismus at final follow-up (P ≤ 0.043). On multivariate analysis, only foveal involvement was found to be significant (P < 0.001). CONCLUSIONS: Strabismus, exotropia in particular, is a common adverse sequela following successful conservative treatment for Rb, with 69% of the present cohort having some type of deviation after long-term follow-up, for which foveal tumor at presentation was found to be a significant risk factor.

CASE REPORT: Here we report a 19-year-old female patient who presented a vasoproliferative tumour. It caused complications, such as epiretinal membrane, macular oedema, vitreous haemorrhage, and exudative retinal detachment. The patient was treated with 3 injections of intravitreal bevacizumab, an intravitreal dexamethasone implant, tocilizumab, and double freeze-thaw cryotherapy. DISCUSSION: Therapeutic options are: observation, if it is small, if it is a peripheral lesion, and if there seems to be no threat to vision. If it requires treatment, laser photocoagulation, intravitreal bevacizumab, trans-conjunctival cryotherapy, transpupillary thermotherapy, photodynamic therapy, brachytherapy plaques and surgery are the different options available. Recently, tocilizumab and intravitreal dexamethasone implants have been reported to be beneficial

[ADVANCES IN THE TREATMENT OF RETINOBLASTOMA AT HADASSAH IN THE LAST THREE DECADES].

INTRODUCTION: Retinoblastoma (RB) is a malignant tumor presenting in the eyes of infants and children, which endangers life, the eye and vision. The treatment of RB has undergone marked changes in recent years, and great progress has been made in our ability to preserve eyes. Over the last three decades most Israeli patients with RB have been treated in the National Specialty Ocular Oncology Service at the Hadassah-Hebrew University Medical Center in Jerusalem. AIMS: To describe advances in the primary treatment of RB with an emphasis on eye-preserving treatments. METHODS: The study included a retrospective cohort of patients who were diagnosed and treated at our center over the last three decades. Review of patients' records was approved by the Hadassah IRB. RESULTS: From 1988 to 2014 we diagnosed 290 children (138 girls - 47.6%). The mean age at diagnosis (±SE) was 18.1±1.2 months, median 12.5 months. RB was unilateral in 55.6% of the cases, bilateral in 41.3% and unilateral multifocal in 3.1%. There was an even distribution of disease severity (IRB grouping). Since the advent of IV chemotherapy (IVC) there has been a decrease in the rate of eye enucleation from ~90% to ~30% of the children until the year 2000 with a stable rate thereafter. In the years 1990-2000 there was an increase followed by a decrease in the use of primary external beam radiotherapy (EBRT), and a parallel small increase in the use of brachytherapy from the mid '90s until today. The recently introduced novel treatments - intravitreal (IVitC) and intra-arterial chemotherapy (IAC) - were used as a complimentary treatment to IVC, and not yet as a single primary modality until 2014. CONCLUSIONS: IVC replaced the need to enucleate in most of the cases, but 30% of children still require a primary enucleation. DISCUSSION: IVC usually requires additive treatments (thermal-cryotherapy, trans-pupillary thermotherapy - TTT, brachytherapy and/or local chemotherapy - IVitC and IAC) and with the use of multi-modal therapy many eyes can be preserved. In the period reported in the current manuscript, the use of IAC as a primary treatment approach was only used in isolated cases. In Summary, There have been significant advances in our ability to save eyes, and the field continues to progress.

Retinoblastoma.

Retinoblastoma represents 3% of all childhood cancers, and is the most common intraocular malignancy of childhood. It is fatal, if untreated. White eye reflex, also known as leukocoria, is the commonest sign, followed by strabismus. The pediatricians have a very important role to play in the diagnosis of this relatively rare, but easily detectable tumor. Early diagnosis yields better results. The management of retinoblastoma has gradually evolved over the past few decades, with an aim to not only preserve life and eye, but also optimize residual vision. The treatment of retinoblastoma is multimodal, with chemotherapy, focal treatment including trans-pupillary thermotherapy, cryotherapy and laser photocoagulation, radiation therapy and surgery, all playing a vital role. Intravenous chemotherapy has been the mainstay of treatment for the past two decades, and still continues to be the most extensively used eye-saving modality of treatment. Periocular and intravitreal chemotherapy have specific indications in the management of retinoblastoma. Intra-arterial chemotherapy has emerged as a promising alternative for advanced and refractory retinoblastoma, both as a primary and secondary therapy. Recent advances in genetics of retinoblastoma have also helped in improving the overall clinical management of this malignancy.

Long-term Visual Acuity, Strabismus, and Nystagmus Outcomes Following Multimodality Treatment in Group D Retinoblastoma Eyes.

PURPOSE: To analyze the long-term visual acuity, strabismus, and nystagmus outcomes in Group D retinoblastoma following multimodality treatments in a national retinoblastoma referral center. DESIGN: Retrospective interventional case series. METHODS: A 13-year retrospective chart review of Group D eyes treated initially with intravenous chemotherapy (IVC) and followed up for at least 1 year from last treatment. Risk factors for final visual acuity (VA) were analyzed, and rate of strabismus and nystagmus at last follow-up visit were calculated. RESULTS: One hundred and four Group D eyes (92 patients) presented to our center during the study period, of which 32 (27 patients) met the inclusion criteria. Following IVC (vincristine, etoposide, and carboplatin), adjuvant treatments included intraophthalmic artery chemotherapy in 5 (16%) eyes, plaque brachytherapy in 5 (16%), transpupillary thermotherapy (TTT) in 18 (56%), and cryotherapy in 24 (75%) eyes. On last examination, 64.41 ± 6.76 months from presentation, mean final VA was 20/283 (logMAR equivalent of 1.15 ± 0.15). On univariate analysis, presentation age, foveal retinoblastoma (at initial examination), use of TTT, and tumor-foveola distance (at last visit) were found to be significant risk factors for worse VA (P < .026). On multivariate analysis, however, only TTT was found to be significant (P = .010). At last visit, 6 of 27 (22%) patients had nystagmus and 12 of 20 (60%) bilaterally salvaged patients had strabismus (n = 10 exotropia and n = 2 esotropia). CONCLUSIONS: After multimodality treatments initiated with IVC, 50% of salvaged Group D retinoblastoma eyes had <20/200 vision, with TTT being a risk factor for worse vision; 60% had strabismus; and 22% had nystagmus.
