RESUMO
Introduction: We aim to report the anatomical and functional outcomes of ruthenium-106 brachytherapy in the management of circumscribed choroidal hemangiomas (CCH). Methods: This is a single-center, retrospective case series including patients with unilateral symptomatic CCH treated with ruthenium-106 brachytherapy at the Cairo University Ocular Oncology Service. Patient records were analyzed for patients' demographics, best corrected visual acuity (BCVA), tumor dimensions (thickness and largest base diameter), foveal subretinal fluid, radiation-related complications, and recurrence. Results: Seven patients were included in the study (including 6 males) with a mean age of 39.3 ± 15.4 years; ruthenium-106 plaque was used to deliver 50 Gray to the tumor apex. After a mean follow-up duration of 12.5 months, all patients had significant improvement in BCVA after treatment, mean tumor height decreased significantly from 4.76 ± 1.76 mm to 1.70 ± 1.2 mm (p value 0.01). The largest tumor base diameter also decreased significantly from 9.13 ± 2.68 mm to 4.65 ± 3.75 mm (p value 0.05). Subretinal fluid and exudative retinal detachment resolved in all patients, and no significant radiation-related complications were observed in any patient. None of the patients needed any further treatment or experienced recurrence within the follow-up period. Conclusion: Ruthenium-106 brachytherapy is an effective tool in the management of symptomatic CCH with a good visual prognosis and safety profile.
RESUMO
Introduction: We aim to explore the safety and efficacy of episcleral brachytherapy as a primary management option for eyes with retinal pigment epithelial (RPE) adenoma. Methods: Retrospective chart review of the demographic, clinical, ancillary, and postoperative outcome data of patients with RPE adenoma in 2 tertiary referral centers. Tumor regression, final visual acuity, and complications were assessed. Results: Five patients (3 females and 2 males) were included. Four of the 5 eyes had peripheral and mid-peripheral lesions, while one tumor was juxtapapillary. Three eyes were treated with ruthenium-106 (100 Gray), and 2 received iodine-125 episcleral plaques (85 Gray). All eyes showed clinical and imaging-based evidence of regression. Four eyes had stable or improved visual acuity, while 1 eye exhibited one line loss of visual acuity due to radiation retinopathy. Local recurrence was not observed in any eye over a median follow-up of 24 (range 6-112) months. Conclusions: Episcleral brachytherapy is an effective management option for select cases of RPE adenoma that is capable of achieving tumor regression while maintaining favorable visual acuity. The initial safety profile of brachytherapy is good without significant vision-compromising complications.
