RETINOBLASTOMA is the most common malignant intraocular tumor in children; it is also one of the most highly curable pediatric solid tumors if detected early. The conventional treatment of retinoblastoma is primary enucleation. Recent research reported a trend toward decreasing frequency of enucleation in the management of retinoblastoma. The trend toward globe-sparing interventions has been largely attributed to earlier diagnosis and recent success with conservative globe-sparing treatment options. Currently, globe-sparing interventions include first-line chemotherapy or chemoreduction, subconjunctival chemotherapy, systemic chemotherapy for metastasis, transpupillary thermotherapy (TIT), chemothermotherapy (CTT), laser photocoagulation, cryotherapy, brachytherapy, and external beam radiotherapy (EBRT). Expanded clinical options currently available have markedly decreased the overall enucleation rate for retinoblastoma CLINICAL SCENARIO: A 10-month old boy is brought to an ophthalmologist because of cats eye reflex in the left eye. The patient had undergone enucleation of his right eye for glaucomatous stage retinoblastoma 6 months earlier. Examination revealed the presence of a solitary retinal mass of about 12 mm in diameter, located nasal to the disc. There was no evidence of vitreous seeding Realizing that this was the only eye of the patient, the ophthalmologist wants to do everything humanly possible to preserve it. He has heard about chemothermotherapy (CTT) but is not sure if this was the best alternative he can offer CLINICAL QUESTION: Among patients with retinoblastoma, is chemoreduction combined with adjuvant treatment effective in preserving the globe and vision?

Objectives: To evaluate the prevalence, etiologies, demographics, and clinical presentation of enucleated pseudoretinoblastoma. Methods: This retrospective study reviewed ocular pathology records of enucleated globes with clinically diagnosed or suspected retinoblastoma submitted to a public university ocular pathology laboratory from 2013 to 2018. Hematoxylin-eosin-stained sections of pseudoretinoblastoma cases were reevaluated, and additional clinical data were taken from hospital charts. Results: Of the 211 enucleated eyes with clinically diagnosed or suspected retinoblastoma, 202 (95.7%) had histologically confirmed retinoblastoma, while 9 (4.3%) had pseudoretinoblastoma. The most common ocular conditions mimicking retinoblastoma were retinal dysplasia (2 eyes) and persistent fetal vasculature (2 eyes). The pseudoretinoblastoma group consisted of 4 females and 5 males, and enucleated were 6 right eyes and 3 left eyes. The mean age at the time of enucleation was 3.65 years, and the mean symptom duration was 17.36 months. Leukocoria, which was noted in 4 patients, was the most frequent initial symptom. No significant difference between the pseudoretinoblastoma group and the retinoblastoma group were found in terms of sex, laterality of the enucleated eye, age at the time of enucleation, and symptom duration. Conclusion In this retrospective review, the prevalence of pseudoretinoblastoma in enucleated globes clinically suspected or diagnosed with retinoblastoma was 4.3%. Persistent fetal vasculature and retinal dysplasia were the most common pseudoretinoblastomas. Clinicians should perform a thorough clinical evaluation and judiciously utilize the available diagnostic means to differentiate retinoblastoma from pseudoretinoblastoma.

PURPOSE: Retinoblastoma (RB) is the most common primary malignant intraocular tumor in children. Although systemic chemotherapy has been the primary treatment, intra-arterial chemotherapy (IAC) represents a new treatment option. Here, we performed alternate systemic chemotherapy and IAC and retrospectively reviewed the efficacy and safety of this approach. METHODS: Patients diagnosed with intraocular RB between January 2000 and December 2011 at Severance Children's Hospital, Yonsei University, were reviewed. Before February 2010, the primary treatment for RB was chemotherapy (non-IAC/CTX). Since February 2010, the primary treatment for RB has been IAC (IAC/CTX). External beam radiotherapy or high-dose chemotherapy were used as "last resort" treatments just prior to enucleation at the time of progression or recurrence during primary treatment. Enucleation-free survival (EFS) and progression-free survival were assessed. RESULTS: We examined 19 patients (median age, 11.9 months; range, 1.4 to 75.6 months) with a sum of 25 eyes, of which, 60.0% were at advanced Reese Ellsworth (RE) stages. The enucleation rate was 33.3% at early RE stages and 81.8% at advanced RE stages (P=0.028). At 36 months, EFS was significantly higher in the IAC/CTX group than in the non-IAC/CTX group (100% vs. 40.0%, P=0.016). All 5 patients treated with IAC achieved eye preservation, although most patients were at advanced RE stages (IV-V). CONCLUSION: Despite the limitation of a small sample size, our work shows that an alternative combined approach using IAC and CTX may be safe and effective for eye preservation in advanced RB.

OBJECTIVETo evaluate the therapeutic effects and complications of hydroxyapatite (HA) orbital implantation on patients after trauma-related surgeries.

METHODSRetrospective analysis was made from 211 cases (211 eyes) who underwent HA orbital implant placement after trauma-related enucleation or evisceration, including 68 cases of evisceration and primary HA implant placement, 77 cases of enucleation and HA implant placement wrapped with multi-windowed sclera, 66 cases of enucleation and HA implant placement free of wrapping. All the cases were followed up for 1-5 years to observe the therapeutic effects and major complications.

RESULTSFive of 211 cases had wound dehiscence. Ten cases had HA implants exposure, including 1 case suffering severe orbital infection and requiring HA implant removal. The implants exposure incidences by the three surgical methods were from 1.30% to 10.06% and averaged 4.74%. Significant difference was found in late exposure incidence and total incidence from the three methods (chi(2)=13.372, P < 0.01 and chi(2)=7.540, P < 0.05). Two cases had shrinkage of the lower fornix. Enophthalmos occurred in 1 case treated by method 1 and was corrected by implanting porous polyethylene (Medpor) plate into the bottom of orbit. In 210 cases, the artificial eye moved well and the cosmetic results were satisfactory.

CONCLUSIONSDifferent surgical methods have their own merit and disadvantage. Enucleation and placement of HA implant wrapped with multi-windowed sclera has corroborated fewer complications than others.

OBJECTIVETo evaluate the clinical value of stereotactic radiosurgery (SRS) for uveal melanoma.

METHODSFrom Jan, 1996 to March, 2004, 16 patients with uveal melanoma were treated with SRS, two by one session (35 Gy, 25 Gy) and fourteen by fractionated SRS (30-55 Gy/2-4F/4-16D). The follow-up period ranged from 3 to 100 months (median: 66 months).

RESULTSAll 16 patients were still alive though all were blind in the diseased eye during recent follow-up. Local control rate was 93.4%, 5-year survival rate of 13 patients who have been followed for more than 5 years, was 100% (13/13). However, 7 patients received eyeball enucleation due to corneal ulcer (n = 2), suspicion for uncontrolled tumor (n = 2) and secondary glaucoma (n = 3). One patient developed distant metastasis, though still alive.

CONCLUSIONFractionated radiosurgery is safe and effective for uveal melanoma. It is indicated for lesions of limited size (longest diameter < 20 mm, depth < 15 mm) located in the posterior pole or behind the equator at the back of the eyeball.

BACKGROUNDLocal resection is an effective method for treating the uveal melanoma. The aim of this study is to evaluate the survival and clinical outcomes of patients with uveal melanoma treated by local resection or enucleation.

METHODSTotally, 167 consecutive patients with uveal melanoma were recruited for the study, of whom 57 patients were treated with local resection and 110 patients were treated with enucleation. The main outcome was measured by the visual acuity, local recurrence, eye retention, metastases, and melanoma-related mortality.

RESULTSThere were statistically significant differences in the largest basal diameter of the tumor (t = -3.441), the tumor thickness (t = -4.140), the ciliary body infiltration (χ(2) = 8.391), and the duration of follow-up (Z = 3.995) between the two groups (P < 0.05). The univariate survival analysis showed that the method of treatment was not significantly associated with metastases. The Cox proportion hazard analysis showed that the risk factors for metastasis involved the age at the time of diagnosis (RR = 1.752, 95% CI 1.066-2.880, P = 0.027), the largest basal diameter of the tumor (RR = 3.508, 95% CI 1.934-6.336, P = 0.000), and the histological type (RR = 2.444, 95% CI 1.106-5.877, P = 0.046). The 5-year metastases rate was 18.60% for the group with local resection and 27.81% for enucleation (χ(2) = 1.214, P > 0.05); the 5-year melanoma-related mortality was 16.27% for the group with local resection and 25.33% for enucleation (χ(2) = 1.304, P > 0.05). The 5-year local tumor recurrence rate was 29.50% and the 5-year accumulated eye retention rate was 69.00% after local resection. The visual acuity which light perception or better of 60 months after local resection was observed in 25 (92.60%) among persons retaining eye.

CONCLUSIONSThe survival outcomes of the patients with local resection were not worse than that of the patients with enucleation, and local resection could make the patient retain eye and partial visual functions. Hence, local resection may be an effective method for patients with uveal melanoma eligible for operation.

Schwannomas rarely present as intraocular tumors and are often misdiagnosed as malignant melanoma. We describe a choroidal schwannoma confirmed by sclerouvectomy. A 30-year-old woman presented with a large nonpigmented intraocular mass of the choroid in the right eye and underwent surgical excision by sclerouvectomy. Histologically, the tumor was composed of a mixture of cellular solid components (Antoni A) and loose myxoid components (Antoni B). The tumor was eventually diagnosed as a schwannoma. Currently available ancillary studies are still of little value in definitively differentiating schwannomas from other choroidal tumors. In the case of atypical findings for a malignant melanoma, a benign neoplasm should be included in the differential diagnosis. This patient avoided enucleation by first having the mass excised. We are unaware of previous reports in which a choroidal schwannoma was diagnosed by surgical excision.
