RESUMO

PURPOSE: To evaluate the efficacy of intravitreal bevacizumab for prevention of macular edema after plaque radiotherapy of uveal melanoma. DESIGN: Retrospective, single-center, nonrandomized, interventional comparative study. PARTICIPANTS: Patients with uveal melanoma treated with plaque radiotherapy were divided into 2 groups: a bevacizumab group and a control group. INTERVENTION: The bevacizumab group received intravitreal bevacizumab injection at the time of plaque removal and every 4 months thereafter for 2 years (total, 7 injections). The control group had no intravitreal bevacizumab injection. Both groups had periodic follow-up with ophthalmoscopy and optical coherence tomography (OCT). MAIN OUTCOME MEASURES: Development of OCT-evident macular edema. RESULTS: There were 292 patients in the bevacizumab group and 126 in the control group. The median foveolar radiation dose was 4292 cGy (bevacizumab) and 4038 cGy (control; P = 0.327). The cumulative incidence of OCT-evident macular edema over 2 years (bevacizumab group vs. control group) was 26% versus 40% (P = 0.004), respectively; that for clinically evident radiation maculopathy was 16% versus 31% (P = 0.001), respectively; that for moderate vision loss was 33% versus 57% (P < 0.001), respectively; and that for poor visual acuity was 15% versus 28% (P = 0.004), respectively. There was no statistically significant difference in clinically evident radiation papillopathy (P = 0.422). Kaplan-Meier estimates at 2 years showed statistically significantly reduced rates of OCT-evident macular edema (P = 0.045) and clinically evident radiation maculopathy (P = 0.040) in the bevacizumab group compared with controls. CONCLUSIONS: Patients receiving intravitreal bevacizumab injection every 4 months after plaque radiotherapy for uveal melanoma demonstrated OCT-evident macular edema, clinically evident radiation maculopathy, moderate vision loss, and poor visual acuity less frequently over a period of 2 years than patients not receiving the injections.

RESUMO

PURPOSE: To describe a series of 20 patients with opaque media, referred with uveal melanoma, but subsequently found to have pseudomelanoma from oblique imaging of hypermature cataract on ultrasonography. DESIGN: Case series. PARTICIPANTS: Twenty patients. METHODS: Retrospective chart review. MAIN OUTCOME MEASURES: Ultrasound imaging. RESULTS: All eyes had opaque media from hypermature cataract with no view of the fundus. All were referred because of suspected uveal melanoma, based on ultrasonographic imaging. The echogenic mass appeared to be in the ciliary body (n = 17) or choroid (n = 3). The median patient age was 54 years (range, 17-86 years). Most patients were white (n = 13) or black (n = 4). There was a history of eye trauma (n = 3) and ocular surgery (n = 1). Visual acuity was light perception to hand movements (n = 18) and 20/50 to 20/100 (n = 2). The cataract was in an anatomic position (n = 18) or subluxated (n = 2). On B-scan ultrasonography, the mass was dome-shaped (n = 10) or elliptical (n = 10), displayed an acoustically hollow center with a dense rim (n = 20), and was located in the ciliary body (n = 17) or choroid (n = 3). The mean thickness was 7.2 mm and the mean base was 9.3 mm. Features suggestive of cataract rather than melanoma included a lack of contiguity with the uvea (n = 20) on videoimaging using standard ultrasonography and ultrasound biomicroscopy, a lack of a transillumination shadow, and a lack of a sentinel vessel. For those in the ciliary body region, an additional feature was the ultrasonographic presence of mass in all 4 quadrants (n = 17), representing oblique imaging of the lens equator. For those in the choroid region, the pseudomelanoma shifted when the patient was imaged in a reclined compared with an upright position. After cataract surgery, the lack of melanoma was confirmed. CONCLUSIONS: Dense cataract can preclude a fundus view, necessitating ultrasonography for imaging the posterior segment of the eye. Ultrasonographic confusion with a ciliary body and choroidal melanoma can occur because the dome-shaped cataract can simulate a dome-shaped melanoma.

RESUMO

PURPOSE: Uveal melanoma (UM) was a fatal malignancy in 40% to 50% of cases. The aim of this study is to evaluate the independent contributions of chromosome 1, 3, 6, and 8 abnormalities for prognostication of metastasis, and to define multichromosome copy number aberration (CNA) signatures that can be used to evaluate risk. METHODS: A series of 320 UM were analyzed for chromosome 1, 3, 6, and 8 abnormalities using whole genome single-nucleotide polymorphism arrays. Results for changes in six chromosomal regions were analyzed using univariate and multivariate Cox proportional hazard modeling to identify significant predictors of metastasis and CNA signatures. RESULTS: Univariate Cox analysis indicated that losses of chromosome 3, 1p, 6q, and 8p and gain of 8q, as well as sex, source of tumor tissue (fine-needle aspiration biopsy [FNAB] compared with tumor from an enucleated eye), tumor basal diameter and height, and ciliary body involvement were all significant predictors of poor metastatic outcome. In the multivariate analysis, loss of chromosome 3 and 8p remained significant after adjusting for the effects of all other variables, as did sex, tissue source, and basal diameter. Multivariate analysis of the joint effects of changes in the six chromosomal regions showed that six signatures, including chromosome 3-loss, 1p-loss, 8p-loss, and/or 8q-gain had hazard ratios (HR) ranging from 7.90 to 37.25. CONCLUSIONS: In UM, tumor size and location, tissue source, and sex were all significantly associated with increased metastasis. In addition, chromosome 3-loss and 8p-loss were found to be independent predictors of poor metastatic outcome and CNA signatures were identified that can add a specific HR value for classification of risk categories.

RESUMO

PURPOSE: To evaluate the outcomes of iris melanoma managed with plaque radiotherapy on the basis of the initial presence or absence of glaucoma. DESIGN: Retrospective, comparative case series. PARTICIPANTS: A total of 144 patients. INTERVENTION: Custom-designed iodine-125 plaque radiotherapy delivering planned 8000 cGy to melanoma apex using transcorneal application. MAIN OUTCOME MEASURES: Tumor control and treatment-related complications. RESULTS: Of 144 patients with iris melanoma, glaucoma was present at the initial visit in 58 (40%). Causes of elevated intraocular pressure included angle infiltration by melanoma in 50 patients (86%), angle neovascularization in 4 patients (7%), and hyphema in 4 patients (7%). At presentation, the eyes displaying iris melanoma with glaucoma (vs. without glaucoma) were statistically more likely to display angle tumor (66% vs. 43%), with minimal thickness (1.9 vs. 2.9 mm), and melanoma seeding in iris stroma (7 vs. 3 clock hours) and angle (5 vs. 2 clock hours). Plaque radiotherapy was performed in all cases. Kaplan-Meier estimates at 7 years post-treatment revealed no statistical differences in outcomes of local recurrence (14% vs. 15%), enucleation (14% vs. 11%), or metastasis (2% vs. 0%) comparing eyes with and without glaucoma. Of the entire group, multivariate analysis for factors predictive of recurrence included partial (vs. complete) anterior segment irradiation and postradiotherapy glaucoma. Factors related to enucleation included diabetes mellitus, poor initial visual acuity, higher radiation dose to tumor apex, and tumor recurrence. There were no factors predictive of metastasis. CONCLUSIONS: Iodine-125 plaque radiotherapy provides adequate tumor control for iris melanoma with a low metastatic potential of 1% at 7 years. Iris melanoma with secondary glaucoma showed a statistically significant greater likelihood of flat tumor with iris and angle seeding and no difference in outcomes compared with eyes without glaucoma.

RESUMO

PURPOSE: To document minimal dose and minimal exposure of chemotherapy for unilateral retinoblastoma. METHODS: A 4-month-old infant developed leukocoria in the right eye and was found to have unilateral sporadic retinoblastoma. RESULTS: The right eye was classified as Group D retinoblastoma, with a single large tumor, moderate subretinal seeding, and total retinal detachment. The retinoblastoma measured 20 mm in basal dimension and 13 mm in ultrasonographic thickness. Options of enucleation, intravenous chemotherapy, and intraarterial chemotherapy were offered, but the latter was chosen because of anticipated, rapid, and more complete response with intraarterial rather than intravenous chemotherapy. After using low dose (3 mg) of single-agent melphalan delivered over 30 minutes into the ostium of the ophthalmic artery of the 4-month-old infant, a complete response with Type 1 regression (complete calcification) of the mass and resolution of all subretinal fluid was found. A second similar dose was delivered to ensure remission of all seeds and tumor with stable findings. Further chemotherapy was stopped. On 6 months of follow-up, the child displayed complete tumor control with 2 cycles of lowest dose (3 mg) intraarterial melphalan. There were no complications. CONCLUSION: In infants younger than 6 months, low dose of only 3-mg single-agent melphalan could be sufficient to control retinoblastoma with minimal exposure.

RESUMO

OBJECTIVE: To determine the long-term safety of pars plana vitrectomy (PPV) in eyes with plaque-irradiated posterior uveal melanoma. METHODS: In this retrospective case series, patients with plaque-irradiated posterior uveal melanoma subsequently underwent PPV for vitreous hemorrhage. The main outcome measures are the rates of intraocular melanoma dissemination, extrascleral extension of melanoma, local melanoma recurrence, and systemic melanoma metastasis after PPV. RESULTS: Forty-seven eyes of 47 patients underwent PPV for vitreous hemorrhage after iodine 125-labeled plaque radiotherapy for choroidal melanoma. The mean interval between the onset of vitreous hemorrhage and PPV was 13 (median, 10; range, 0-52) months. The mean time from PPV to last follow-up was 5 (range, 0.5-16) years. There were no cases of intraocular melanoma dissemination or extrascleral extension of melanoma. One patient (2%) developed local choroidal melanoma recurrence (2 years after PPV and 5 years after initial plaque radiotherapy) and was successfully managed with transpupillary thermotherapy. Systemic melanoma metastasis occurred in 4 patients (9%) during a mean interval of 5 years after plaque radiotherapy. During follow-up, 43 patients (91%) were alive without systemic metastasis and 4 patients (9%) were alive with metastasis. CONCLUSION: Management of vitreous hemorrhage by PPV in eyes with previously irradiated uveal melanoma appears to be safe and without increased risk for intraocular, local, orbital, or systemic dissemination of the tumor.

RESUMO

BACKGROUND AND OBJECTIVE: To evaluate clinical features, course, and outcome of patients with acute exudative paraneoplastic polymorphous vitelliform maculopathy (AEPPVM). PATIENTS AND METHODS: Retrospective case series of 5 patients. RESULTS: There were 3 males and 2 females, with a median age of 74 years. The primary neoplasms were cutaneous melanoma (n = 2), choroidal melanoma (n = 1), lung adenocarcinoma (n = 1), and lung plus breast adenocarcinoma (n = 1). The mean interval between the diagnosis of the primary neoplasm and the diagnosis of AEPPVM was 42 months. The presenting symptom was blurred vision in all cases. Ophthalmoscopy disclosed multifocal localized shallow serous detachments of the post-equatorial neurosensory retina with yellow-white subretinal debris confirmed by optical coherence tomography (OCT). There was a mean of 21 individual sites of detachment per eye, each measuring a mean of approximately 0.8 millimeter in diameter. Fundus autofluorescence depicted hyperautofluorescence corresponding to the detachments. After mean follow-up of 5 months, three patients had died of metastases. Of the two survivors, one showed resolution of lesions and the other was unchanged. CONCLUSION: AEPPVM is a paraneoplastic retinopathy found in patients with metastatic melanoma or carcinoma. The most salient feature is reduced visual acuity from multifocal shallow retinal detachments less than 1-mm diameter, best depicted on OCT.

RESUMO

Retinoblastoma is a deadly eye cancer in children, leading to death in 50%-70% of children in undeveloped nations who are diagnosed with it. This malignancy is the most common intraocular tumor in childhood worldwide. The good prognosis in developed nations is related to early detection and advanced treatments. With the advent of intraarterial chemotherapy, neurosurgeons have taken a central role in the treatment of this pediatric condition. Intraarterial chemotherapy is a novel treatment for retinoblastoma whereby chemotherapeutic agents are precisely delivered into the ophthalmic artery, minimizing systemic toxicity. This procedure has shown impressive results and has allowed a dramatic decrease in the rate of enucleation (eye removal) in advanced and refractory retinoblastoma. Recent reports have raised some concerns about the risk of ocular vasculopathy, radiation-related toxicity, and the potential for metastatic disease after intraarterial chemotherapy. In the authors' experience of more than 3 years, tumor control is excellent with globe salvage at 67% and vascular events less than 5%, mostly related to improvement in technique. The role of this novel approach in the management of retinoblastoma has yet to be defined. As more centers are adopting the technique, the topic will decidedly become the focus of intensive future research. In this paper, the authors review and discuss current data regarding intraarterial chemotherapy for retinoblastoma.

RESUMO

OBJECTIVE: To assess the long-term results of chemotherapy for cavitary retinoblastoma. METHODS: Retrospective, nonrandomized, interventional case series of 26 cavitary retinoblastomas in 25 eyes of 24 patients. Retinoblastomas were treated with intravenous chemoreduction and/or intra-arterial chemotherapy. Main outcome measures included tumor control, globe salvage, and metastasis. RESULTS: Of 24 patients with cavitary retinoblastoma, the mean age at diagnosis was 16 months. The mean number of cavitary tumors per eye was 1 (median, 1; range, 1-2), with a mean tumor basal diameter of 13 (median, 13; range, 7-24) mm and mean tumor thickness of 7 (median, 6; range, 3-17) mm. The mean number of cavities per tumor was 2 (median, 2; range, 1-5), with a mean cavity diameter of 3 (median, 2; range, 1-10) mm. Related features included vitreous seeds in 7 tumors (27%), subretinal seeds in 6 (23%), and subretinal fluid in 13 (50%). Intravenous chemoreduction was used in 23 tumors (88%); intra-arterial chemotherapy, in 2 (8%); and both, in 1 (4%). After treatment, the mean reduction in tumor base was 22% and mean reduction in tumor thickness was 29%. Despite minimal reduction, tumor recurrence was noted in only 1 eye (4%), globe salvage was achieved in 22 (88%), and there were no cases of metastasis or death during 49 (range, 6-189) months of follow-up. CONCLUSION: Despite minimal visible tumor response to chemotherapy, cavitary retinoblastoma displays relatively stable long-term results.

RESUMO

OBJECTIVE: To investigate the role of sector laser photocoagulation for prevention of macular edema after plaque radiotherapy for uveal melanoma. METHODS: Noncomparative, pilot interventional case series. The main outcome measure was optical coherence tomography-evident macular edema. RESULTS: A total of 29 patients had sector laser photocoagulation (sector panretinal photocoagulation) and sub-Tenon triamcinolone injection. The median tumor thickness and base was 3.3 mm and 10.0 mm. The median radiation dose and rate to the macula was 2,944 cGy and 31.0 cGy/hour. At the 12-month and 24-months follow-up, cystoid macular edema was found in 17% and 24% of the sector panretinal photocoagulation group. There were no major side effects registered. CONCLUSION: Sector panretinal photocoagulation in combination with sub-Tenon triamcinolone appears to show potential as a safe and beneficial intervention for the prevention of macular edema after plaque radiotherapy for uveal melanoma in this series.

RESUMO

An otherwise healthy 15-month-old boy presented with benign branchial cleft cysts and combined hamartoma of the retina and retinal pigment epithelium. This association was previously only reported in a patient with branchio-oculo-facial syndrome. Although uncommon, this could represent multifocal sites of fetus craniofacial malformation.

RESUMO

PURPOSE OF REVIEW: To review the recent literature on two methods of chemotherapy for retinoblastoma using intravenous versus intra-arterial route. RECENT FINDINGS: In 1996, the era of intravenous chemotherapy (chemoreduction) for retinoblastoma was introduced with major centers providing published information on impressive tumor control, without the need for external beam radiotherapy or enucleation. Later reports heralded continued impressive long-term control, minimal systemic toxicities, likely prevention of pinealoblastoma (trilateral retinoblastoma), and reduction in numbers of germline mutation second cancers. There is no reported ophthalmic toxicity and no evidence of reduction in fertility with chemoreduction. In 2011, the era of intra-arterial chemotherapy was announced with several studies and three conflicting editorials in the literature. This technique requires a catheterization through the arterial tree from the femoral artery into the ophthalmic artery. Outstanding tumor control is achieved with only three cycles, but more-than-expected ocular ischemic events have been noted. Further improvements in this technique could minimize complications. SUMMARY: Both intravenous and intra-arterial chemotherapy are powerful methods for retinoblastoma control. In addition to tumor control, intravenous chemotherapy protects from systemic metastasis and pinealoblastoma, minimizes long-term second cancers, and has few systemic and no ocular toxicities. Intra-arterial chemotherapy provides excellent tumor control for slightly more advanced eyes with retinoblastoma and, in addition, can be used to treat eyes that fail other methods. However, local ocular toxicities can be vision-threatening and long-term systemic toxicities are not yet understood.

RESUMO

PURPOSE: The purpose of this article is to determine the incidence, etiology, management, and outcome of vitreous hemorrhage (VH) after plaque radiotherapy for uveal melanoma. METHODS: Retrospective review of medical records. RESULTS: Of 3,707 eyes treated with plaque radiotherapy for uveal melanoma, VH developed in 4.1% at 1 year, 15.1% at 5 years, and 18.6% at 10 years by Kaplan-Meier analysis. Presumed causes of VH included tumor necrosis (29%), proliferative radiation retinopathy (24%), posterior vitreous detachment (16%), vascular occlusion (5%), and unknown (19%). Tumor necrosis was the most common cause of VH early in the follow-up period (3% at 1 year), while proliferative radiation retinopathy was the most common source of VH later (6.2% at 15 years). The most common initial management was conservative observation for resolution in 48%, laser photocoagulation in 24%, and vitrectomy in 18%. After a mean follow-up period of 5 years, the VH was completely resolved in 41%, partially resolved in 19%, unresolved in 20%, worsened in 5%, and enucleation was necessary in 15%. By multivariable analysis, risk factors for development of VH were the presence of diabetic retinopathy at first visit (relative risk, 6.64), shorter tumor distance to the optic disc (relative risk, 1.07), greater initial tumor thickness (relative risk, 1.1), and break in the Bruch membrane (relative risk, 2.93). The rates of local tumor recurrence, extraocular extension, and distant metastasis in 74 patients who underwent vitrectomy for VH removal after tumor regression were similar to those in patients who did not have vitrectomy for VH. CONCLUSION: Vitreous hemorrhage occurs after plaque radiotherapy for uveal melanoma in 15.1% of the patients by 5 years. The main factors predictive of VH included underlying diabetic retinopathy, closer tumor proximity to the disc, greater tumor thickness, and break in the Bruch membrane. After tumor regression, vitrectomy for blood removal appears to be safe.

RESUMO

PURPOSE: To describe the clinical, imaging, and pathology features of oncocytic lesions in the ocular adnexa. METHODS: Retrospective, noncomparative, interventional case series. RESULTS: Fifteen oncocytic neoplasms (n = 15 patients) were classified as oncocytoma in 14 (93%) and oncocytic hyperplasia in 1 (7%). The mean patient age was 66 years (median = 66, range = 44-82), and 9 (60%) were male. The tumor involved the caruncle (n = 13, 86%), bulbar conjunctiva (n = 1, 7%), and plica semilunaris (n = 1, 7%). All cases were unifocal and most often presented as a painless mass (n = 12, 80%), evolving over a median 6 months (mean = 12, range = 1-48 months). The mean tumor base was 4.1 mm (median = 4.0, range = 1-10), and the tumor was well-circumscribed (n = 14), dark blue (n = 7), and cystic (n = 10). Ultrasound biomicroscopy and anterior segment optical coherence tomography disclosed mixed solid and cystic components. Complete surgical excision was curative without recurrence after a mean follow up of 39 months. Histopathology disclosed columnar cells with copious quantities of intensely eosinophilic cytoplasm in the lining epithelium (oncocytic hyperplasia) and in some cases with cystadenomatous proliferation (oncocytoma). CONCLUSION: Oncocytic lesions of the ocular adnexae are typically well-circumscribed, cystic lesions that most often involve the caruncle. Surgical excision can be curative.

RESUMO

PURPOSE: To assess the efficacy of less than 3 cycles of intra-arterial chemotherapy (IAC) for retinoblastoma. DESIGN: Retrospective, nonrandomized, interventional case series. PARTICIPANTS: Eight patients. INTERVENTION: Intra-arterial chemotherapy. MAIN OUTCOME MEASURES: Tumor control and globe salvage. RESULTS: Eight patients received fewer than 3 cycles of IAC for retinoblastoma because there was complete tumor control with no residual viable tumor (n = 7) or poor response (n = 1) with little hope that further therapy would benefit the patient. In 3 cases, additional vascular compromise precluded further IAC. The treatment was primary in 6 cases and secondary after failure of other treatment in 2 cases. The 8 eyes were classified (International Classification of Retinoblastoma) as group C (n = 2), group D (n = 3), group E (n = 1), and secondary treatment (n = 2). At initial examination, the main tumor showed a mean basal diameter of 16 mm, a thickness of 8.6 mm, vitreous seeds (n = 2), subretinal seeds (n = 6), and iris neovascularization (n = 1). Three patients were treated with a single cycle of IAC, and 5 patients were treated with 2 cycles of IAC. After IAC, complete tumor response was found in 7 eyes (88%) and partial response was found in 1 eye (13%). Over a mean of 13 months follow-up, there was intraretinal tumor recurrence (n = 1), subretinal seed recurrence (n = 1), and no case of vitreous seed recurrence. Globe salvage was achieved in 2 of 2 group C eyes (100%), 3 of 3 group D eyes (100%), 0 of 1 group E eye (0%), and 1 of 2 secondary treatment eyes (50%). Globe salvage was achieved in 6 of 8 eyes (75%), and 2 of 8 eyes (25%) required enucleation. CONCLUSIONS: One or 2 cycles of IAC can be sufficient for selected eyes with group C or D retinoblastoma, with remarkable tumor control.

RESUMO

PURPOSE: To evaluate plaque radiotherapy for management of residual or recurrent iris melanoma after surgical resection. DESIGN: Retrospective, nonrandomized interventional case series. PARTICIPANTS: We included 32 patients with residual or recurrent iris melanoma after surgical resection. INTERVENTION: Custom designed iodine-125 plaque radiotherapy. MAIN OUTCOME MEASURES: Tumor control, recurrence, poor visual acuity, enucleation, metastasis, and radiation complications. RESULTS: There were 32 eyes with residual (n = 12) or recurrent (n = 20) iris melanoma after surgical resection that were treated with iodine-125 plaque radiotherapy. The residual melanoma was evident clinically in 3 cases and histopathologically in 9; plaque radiotherapy was delivered at a mean interval of 2 months after resection. For the recurrent cases, the mean interval from initial tumor resection to detection of recurrence was 58 months, at which time plaque radiotherapy was applied. For all cases, the mean tumor basal diameter was 6 mm (range, 1-13) and thickness was 2 mm (range, 0.8-4.0) at the time of radiotherapy. Anterior chamber seeding was present in 26 (81%) eyes and glaucoma in 11 (34%) eyes. Visual acuity at presentation was good (20/20-20/50) in 27 (84%), intermediate (20/60-20/150) in 3 (9%), and poor (≤20/200) in 2 eyes (6%). At 6 years after plaque radiotherapy, outcomes included complete tumor control in 87%, poor visual acuity in 9%, enucleation in 13% (for reasons of tumor recurrence [n = 3] and severe glaucoma [n = 1]), and metastasis in 3%. At 6 years, radiation complications included corneal epitheliopathy in 6%, scleral necrosis in 3%, cataract in 53%, elevated intraocular pressure (from tumor or radiotherapy) in 19%, and macular edema in 6%. CONCLUSIONS: Iodine-125 plaque radiotherapy is effective in the management of residual or recurrent iris melanoma after surgical resection, providing tumor control in 87% of patients at 6 years and avoiding enucleation in most cases.

RESUMO

PURPOSE: To study the effect of intraarterial chemotherapy (IAC) on retinoblastoma-induced retinal detachment. METHODS: Retrospective, noncomparative, interventional case series including 15 patients, with intraarterial (ophthalmic artery) chemotherapy as the intervention. Resolution of retinal detachment was the main outcome measure. RESULTS: Of 15 patients with retinoblastoma-induced retinal detachment managed with IAC, 7 (47%) presented with total retinal detachment and 8 (53%) with partial detachment. The eyes were classified as International Classification of Retinoblastoma group C (n = 2, 13%), group D (n = 4, 27%), and group E (n = 5, 33%). There were 4 eyes (27%) that received IAC as secondary treatment after the failure of other treatment methods. After IAC, all tumors showed regression. Of the 7 eyes with initial total retinal detachment, complete resolution of fluid was found in 3 (43%) and partial resolution in 4 (57%). Of the 8 eyes with initial partial retinal detachment, complete resolution of subretinal fluid was found in all 8 (100%), but 1 eye later developed recurrent subretinal fluid. The mean interval to complete resolution of subretinal fluid was 2 months. Globe salvage was achieved in 5 of 7 eyes (71%) with total retinal detachment and 6 of 8 eyes (75%) with partial retinal detachment. CONCLUSION: Eyes with retinoblastoma-induced total or partial retinal detachment showed complete resolution of detachment after IAC in 43% and 100%, respectively.

RESUMO

PURPOSE: To report 10 cases of occult choroidal neovascularization (CNV) associated with choroidal nevus managed with intravitreal bevacizumab. METHODS: Interventional case series. Each nevus was examined and imaged with fluorescein angiography, B-scan ultrasonography, and optical coherence tomography. Data were retrospectively analyzed to evaluate outcomes of treatment response and visual acuity. RESULTS: Nine patients presented with CNV overlying a chronic choroidal nevus with a posterior margin within 1.5 mm of the foveola. In the 10th patient, the posterior margin of the nevus was located 10 mm from the foveola with extension of subretinal fluid into the macula. The CNV was subfoveolar in four cases, juxtafoveolar in two cases, and extrafoveolar in four cases. Initial visual acuity was 20/20 to 20/50 in 5, 20/60 to 20/100 in 2, and 20/200 or worse in 3 cases. Clinical features included subfoveolar fluid in nine, exudation in five, and hemorrhage in four cases. Intravitreal bevacizumab (1.25 mg/0.05 cc) was injected with regression of CNV in all 10 cases using 2 to 14 injections (median 3 injections). In 2 eyes, after therapeutic response to bevacizumab later consolidation with photodynamic therapy (juxtafoveolar CNV) (n = 1) or conventional laser (extrafoveolar CNV) (n = 1) was provided. In the remaining 8 eyes, after discontinuation of bevacizumab, there was no recurrence of CNV over mean 10.1 months. At overall mean follow-up of 22.5 months, final visual acuity decreased by 1 line in 4 cases and improved by mean of 3 lines (range, 1-8 lines) in 6 cases. There were no adverse effects from bevacizumab injections. All 10 choroidal nevi remained stable. CONCLUSION: Intravitreal bevacizumab appears to be an effective treatment option for CNV secondary to choroidal nevus. In some cases, depending on the proximity of the CNV to the foveola, photodynamic therapy or conventional laser may be useful adjunctive therapy.
