Abstract
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.
