Eye Salvage with Combination of Intravitreal and Intracameral Melphalan Injection for Recurrent Retinoblastoma with Anterior Chamber Involvement: Report of a Case
Bibliographic record
Abstract
AIMS: Herein we report successful eye salvage following combined intravitreal and intracameral administration of melphalan for anterior chamber recurrence of retinoblastoma. METHODS: A 12-month-old boy was referred with a sporadic bilateral retinoblastoma staged as group D and V in the right eye and group E and V in the left eye. Treatment initially involved 6 cycles of 3 drugs followed by focal treatments. The left eye was enucleated. Three months after the end of systemic chemotherapy, multiple recurrent lesions were noted in the ciliary body and the anterior chamber. A series of intravitreal (IVT) and intracameral (IC) injections of melphalan combined with a 7th cycle of systemic chemotherapy was performed. The therapeutic schedule alternated: week A an IVT of melphalan (30 μg/0.1 mL) for a total of 4 versus week B IC injections of melphalan (15 μg/0.05 mL) 4 IC in total. Each injection was preceded by an anterior chamber. Cryotherapy to the injection punctures was systematically performed. RESULTS: Rapidly, iris and ciliary body nodules regressed completely based on clinical and ultrasound biomicroscopic examinations. After 3 years of follow-up, the patient has shown no evidence of recurrence. CONCLUSION: In our patient, combined IVT and IC administration of melphalan proved highly efficacious in eradicating the ciliary body and anterior chamber disease and salvage of his one remaining functional eye.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
