Purpose. The purpose of this case report is to present the findings of optical coherence tomography angiography (OCTA) of a patient with bilateral choroidal neovascularization (CNV) associated with optic disc drusen (ODD), who was treated with intravitreal aflibercept injection. Case presentation. A 14-year-old girl presented with a complaint of visual loss and metamorphopsia in her both eyes. Best-corrected visual acuity (BCVA) was 20/32 and 20/25, respectively, in the right and left eyes. Intraocular pressure and anterior segment examination were normal. Dilated fundus examination revealed elevated optic discs with blurred margins in both eyes. In addition, slightly elevated yellow lesion extending from optic nerve head to the macula was observed bilaterally. The patient underwent imaging with colour fundus photography, fundus autofluorescence (FAF), fundus fluorescein angiography (FFA), spectral-domain optic coherence tomography (SD-OCT), OCTA, orbital ultrasonography (USG), and computed tomography (CT). In particular, OCTA demonstrated clearly the large circular CNV complex in the right eye and the CNV structure in the left eye containing slightly activated main trunk and minimal vessel loops in the papillomacular region. CNV secondary to bilateral ODD was suspected. Intravitreal aflibercept injections were performed in 3 doses to the right eye and a single dose to the left eye. After the injections, BCVA reached its complete level in both eyes. SD-OCT revealed irregularity of RPE in the temporal region of the optic disc and complete regression of the subretinal fluid. Interestingly, the entire CNV complex including the main trunk completely disappeared in OCTA. CNV complex was not observed in OCTA during 1-year follow-up, and peripapillary and macular vascular density measurements did not show any significant change. BCVA was preserved, and no additional injections were needed. Conclusion. It is possible that OCTA can be used for detailed evaluation of CNV associated with ODD, response to anti-VEGF treatment, and peripapillary and macular vascular density. There is a need for further studies to confirm the changes such as disappearance of CNV in OCTA after injection as we observed in our patient.

Basidiomiçetlerden kapsüllü bir maya olan Cryptococcus neoformans çoğunlukla immünsistemi baskılanmış hastalarda (transplant alıcılarında, radyoterapi, kemoterapi ve immünsüpresif tedavi görenlerde, immün yetmezlik yaratan hastalığı olanlar gibi) primer infeksiyon etkenidir. Eucalyptus spp ağaçları sıklıkla kolonize olduğu fora elemanlarıdır. Bu çalışmada, Denizli’de turistik Karahayıt kasabasındaki Eucalyptus camaldulensis forasında insan patojeni C.neoformans varlığının aranması hedefenmiştir. Karahayıt kasabasında bulunan 37 E.camaldulensis ağacından eküvyonla örnekleme tekniği ile 117 örnek alındı. Kültür için Staib agar besiyeri kullanıldı. Sonuç olarak, yoğun örnekleme metodu uygulanmasına rağmen Karahayıt bölgesinde insan patojeni C.neoformans’ın kolonize olduğu E.camaldulensis ağacı bulunamamıştır. Yoğun nüfusa sahip ve turizmin önemli olduğu bölgelerde çevresel insan patojeni mayaların varlığının taranması koruyucu hekimlik açısından önemlidir.
