Abstract

Purpose: To evaluate the outcome of Nd: YAG laser iridotomy in patients with pigment dispersion. Methods: Fiftyfour eyes of 28 patients with pigment dispersion syndrome or pigmentary glaucoma were involved in that prospective study. Patients underwent visual acuity measure-ment, slit-lamp biomicroscopy, gonioscopic and fundoscopic examinations, intraocular pressure (IOP) measurement, A-scan ultrasonography and visual field examinations. Nd: YAG laser iridoctomy was performed on randomly chosen 16 eyes of 8 patient and they were f olio wed-up with a mean of 19.8 months (6-37 months). Results: IOP levels of the patients after laser iridotomy were at least 2 mmHg lower than before (mean 3.4, maximum 9.0 mmHg). When the baseline and the last IOP measurements we-re compared in cases with iridotomy the last IOP level was statistically significantly lower (p=0.038). Although, iris concavity was decreased, central anterior chamber depth did not changed after iridotomy. Conclusion: Following the laser iridotomy in cases with pigment dispersion, flattening of the iris causes a decrease in iris-lens contact and angle width, which results in less IOP increase. To understand the effect of laser iridotomy in such cases multicenter studies with large numbers may be needed.

Özet

Amaç: Pigment dispersiyon sendromlu ve pigmenter glokomlu olgularda Nd: YAG laser İridotominin etkisini incelemek. Hastalar ve Metod: Bu prospektif çalışmada 28 pigment dispersiyonlu olgunun 54 gözünün görme keskinliği ölçüldü, biyomikroskobik muayeneleri, gonioskopik ve fundoskopik incelemeleri, göziçi basınç (GİB) ölçümleri, A-Mod ultrasonografi ile ölçümleri ve görme alan muayeneleri yapıldı. 8 olgunun 16 gözüne Nd: YAG laser iridotomi uygulandı. Olgular ortalama 19.8 ay (6-37 ay) takip edildiler. Sonuçlar: YAG laser iridotomi uygulanan olgularda GİB değerleri iridotomi sonrasında en az 2 mmHg, ortalama 3.4 mmHg, en fazla 9.0 mmHg düşüş göstermiştir. Son ölçülen GİB değerleri karşılaştırıldığında istatistiki olarak anlamlı şekilde düşüş izlenmiştir (p= 0.038). İridoto-miden sonra iris konkavitesi azalmasına rağmen merkez ön kamara derinliği değişmemektedir. Yorum: Pigment dispersiyonunda laser iridotomiyi takiben irisdeki düzleşme iris-lens temasını ve açı genişliğini azaltmakta, GİB yükselmesinde azalmaya neden olmaktadır. Laser İridotominin etkilerini daha iyi değerlendirebilmek için çok merkezli çalışmalarla daha çok olgu üzerinde incelemelere ihtiyaç vardır.
