Abstract

Purpose: To investigate the effectiveness of laser photocoagulation of juxtafoveal choroidal neovascularization(CNV) secondary to different etiologies. Materials and Methods: Nine eyes of 9 patients with CNV were reviewed. Seven eyes with juxtafoveal CNV secondary to age-related macular degeneration and 2 eyes with idiopathic juxtafoveal CNV were treated with argon green laser photocoagulation. Results: The patients were followed-up between 3-24 months (median 12 months). Pretreatment visual acuities (VA) were ranging between counting finger at 4 meter and 0.9. VA's were 0.1 at 3 months, counting finger at 5 meter at 6- month, counting finger at 4 meter at 12- month and counting finger at 3 meter at 24-month. Persistant CNV occured in 4 eyes (44.4%) and these eyes received multipl laser treament. Recurrence was observed in 5 eyes (55.5%). Complete destruction of CNV with one session laser treatment could be achieved in 3 eyes(33,3%). Conclusion: Laser photocogulation of juxtafoveal CNV can prevent loss of visual acuity. However , high persistant and recurrent CNV rate occur due to localization of CNV's in this group.

Özet

Amaç: Bu çalışmada amaç değişik etiyolojilere sekonder olarak gelişen jukstafoveal yerleşimli koroidal neovaskülarizasyonlarda (KNV) lazer fotokoagülasyon tedavisinin etkinliğini araştırmaktır. Gereç ve Yöntem: Dokuz hastanın 9 gözü çalışma kapsamına alınmıştır. Gözlerin 7'sinde yaşa bağlı makula dejenerasyonuna sekonder olarak gelişmiş ve 2 gözde de idiyopatik jukstafoveal KNV mevcuttu. Tüm olgulara argon yeşil lazer fotokoagülasyon uygulandı. Bulgular: Hastalar 3 ile 24 ay (median 12 ay) takip edildi. Görme keskinlikleri snellen eşeli ile tedavi öncesi 4 metreden parmak sayma ile 0.9 arasında değişmekteydi. Tedaviden sonra ortalama görme keskinlikleri 3. ayda 0.1, 6. ayda 5 mps, 12. ayda 4 mps ve 24. aylarda ise 3 mps düzeyinde idi. Dokuz gözün 4'ünde (%44.4) persistan KNV izlendi. Bu gözlere birden fazla seansta laser tedavisi uygulandı. Takipler sırasında 5(%55.5) gözde ise rekürrens gözlendi. 3(%33.3) gözde tek seans laser tedavisi ile KNV'nin komplet destrüksiyonu sağlandı. Sonuç: Jukstafoveal KNV'ların lazer fotokoagülasyon ile tedavisi görme keskinliğindeki azalmayı önleyebilir. Fakat bu grup KNV'lerde lokalizasyonları nedeni ile persistan ve rekürren KNV görülme olasılığı fazladır.
