Laser photocoagulation for choroidal neovascular membrane associated with optic disc drusen.

Purpose: To report two cases of choroidal neovascular membrane associated with optic disc drusen which were successfully treated using argon laser photocoagulation.

Methods: Choroidal neovascular complications of optic disc drusen were diagnosed in two of our patients, a 36-year-old woman and a 14-year-old girl. In both cases visual acuity was 20/100 in the affected eye. Fundus examination and angiography revealed a choroidal neovascular membrane. Computer tomography identified bilateral calcified drusen of the optic discs. Photocoagulation of neovascular tissues was immediately performed.

Results: Visual acuity improved progressively, reaching 20/20 10 months after treatment in one case and 20/30 in the other. No recurrence was observed during follow-up.

Conclusion: Early diagnosis and immediate laser photocoagulation of vision-threatening choroidal neovascular membranes associated with optic disc drusen helps stop progression towards the macula and improves longterm visual acuity.
