Non-penetrating deep sclerectomy in unilateral open-angle glaucoma secondary to idiopathic dilated episcleral veins.

PURPOSE: To investigate the efficacy of non-penetrating deep sclerectomy (NPDS) in a secondary open-angle glaucoma case due to dilated episcleral veins, on intraocular pressure and retrobulbar hemodynamics.

METHODS

NPDS was done on a 32-year-old male unilateral open-angle glaucoma secondary to idiopathic dilated episcleral veins.

RESULTS

Except for hyphema and shallow anterior chamber on the first post-operative day, no other complications were observed. Intraocular pressure was 18-20 mmHg during the first six months, without medication or visual loss. Retrobulbar color Doppler imaging showed normal mean and end-diastolic velocities and pulsatility indices of the posterior ciliary and central retinal arteries at end of the first post-operative year.

CONCLUSIONS

NPDS may be an alternative to trabeculectomy in open-angle glaucoma secondary to dilated episcleral veins.
