Treatment of Extrapapillary Retinal Hemangioblastoma Up to 1.5 mm (One Disc Diameter)
Clinical Scenario
This protocol applies to extrapapillary retinal hemangioblastoma with a maximum diameter of 1.5 mm (one disc diameter). Tumors of this size and location are amenable to a laser-based ablative approach as a first-line intervention.
Treatment Approach
The established intervention for lesions of this size involves thermal laser photocoagulation directed at the tumor, which may be performed across one or more sessions. The specific technique parameters, session planning, and retreatment criteria are detailed in the full protocol.
Complete regimen — including technique details and retreatment schedule — available via the link below.
Treatment Goals
Successful ablation is indicated by the formation of a chorioretinal scar at the lesion site, with no re-growth or recurrent exudation on long-term follow-up. Reassessment for potential retreatment is recommended within 3 to 6 months after laser application.

- Extrapapillary RH up to 1.5 mm (one disc diameter) in diameter can reliably be ablated using thermal laser photocoagulation across one or more treatment sessions.
- The treatment technique for small tumors involves a longer burn duration (usually 0.2 to 0.4 seconds) than would be typical for panretinal photocoagulation or laser retinopexy, with power sufficient to create prominent whitening, and with application of burns sufficient to blanch the entire tumor surface.
- The only definitive measure for success is documentation of no re-growth or recurrent exudation over long-term follow up.
- Assessment for re-treatment is advisable within 3 to 6 months after laser application, and the technique for re-treatment is the same.
