Purpose: To evaluate anatomical and functional results of perforating pars plana sclerotomy in 2 patients with the idiopathic uveal effusion syndrome (IUES). Methods: In two patients with IUES the perforating pars plana sclerotomy was performed. During the surgery samples of the suprachoroidal fluid for bioche-mical analysis of protein fractions were taken. Results: During the follow-up period (average 4 years) the retina and the choro-id attached, and the centrál visual acuity (VA) improved as well in both patients. Conclusion: In IUES, the conservative treatment is not effective. Perforating pars plana sclerotomy is treatment of choice and it had positive anatomical and functional effect in both our patients with IUES.
