1/3. High-frequency ultrasound of anterior segment retinoblastoma.PURPOSE: To evaluate anterior segment retinoblastoma with high-frequency ultrasound. DESIGN: Interventional case report. methods: An 11-year-old boy with a total retinal detachment and multiple white anterior chamber nodules was examined with high-frequency ultrasound before enucleation of the globe. RESULTS: Multiple solid and cystic nodular tumors were found in the anterior chamber angle. With high-frequency ultrasound, tumor was discovered posterior to the iris, over the ciliary processes, and on the lens capsule. No calcifications were noted. Other findings included angle closure related to iris neovascularization and uveal thickening. CONCLUSION: High-frequency ultrasound can be used to evaluate retinoblastoma extension into the anterior segment. These images may be used for comparison in future cases of retinoblastoma with anterior chamber invasion.- - - - - - - - - - ranking = 1keywords = neovascularization (Clic here for more details about this article) |
2/3. retinal neovascularization associated with retinoblastoma.PURPOSE: To report retinal neovascularization associated with retinoblastoma in a 14-month-old infant. DESIGN: Observational case report. methods: review of clinical and pathologic findings. RESULTS: A large frond of retinal neovascularization was present posterior to the lens in the right eye, which also contained a retinoblastoma. CONCLUSIONS: retinal neovascularization is an unusual association with retinoblastoma.- - - - - - - - - - ranking = 7keywords = neovascularization (Clic here for more details about this article) |
3/3. glaucoma in retinoblastoma.The association between retinoblastoma and secondary glaucoma is well known. The most common cause of secondary glaucoma in retinoblastoma is iris neovascularization (NVI) followed by pupillary block and tumor seeding of the anterior chamber. Although glaucoma is a secondary clinical issue in retinoblastoma (RB) management and care, awareness of its presence, revealed by a thorough ocular exam of the anterior segment, can guide the clinician in assessing the overall condition of the affected eye.- - - - - - - - - - ranking = 1keywords = neovascularization (Clic here for more details about this article) |
