Abstract

A 9-year-old otherwise healthy boy was examined due to a 4-day history of visual decline in his right eye. Ophthalmological examination revealed an area of active retinochoroiditis in the right macula. Indocyanine green angiography (ICGA) demonstrated multiple hypocyanescent dots surrounding the active lesion extending 360 degrees towards the equator. Optical coherence tomography angiography (OCTA) exhibited dark dots on the choriocapillaris slab over areas corresponding to the hypocyanescent dots detected with ICGA. Full systemic examination and laboratory investigations were carried out. Toxoplasma gondii serology was positive. The diagnosis of toxoplasmic chorioretinitis with white dot-like choroidal involvement was made. Trimethoprim/sulfamethoxazole, azithromycin, and oral prednisolone were administered orally. On repeated ICGA 2 weeks later, the scattered hypocyanescent dots were significantly fewer in number. A month later, right visual acuity was improved, the macular chorioretinitis focus had become inactive, an epiretinal membrane had formed, and the dark dots on the choriocapillaris slab of OCTA were markedly diminished. ICGA may be helpful to observe possible, subtle choroidal involvement in patients with toxoplasmic chorioretinitis.

Özet

Dokuz yaşında sağlıklı, erkek çocuğu sağ gözünde dört günlük görme azlığı yakınması ile muayene edildi. Sağ göz makülasında yerleşen aktif koryoretinit odağı saptandı. İndosiyanin yeşil anjiyografide (İSYA) lezyon etrafında ekvatora kadar 360 derece dağılım gösteren çok sayıda hiposiyanesan nokta görüldü. Optik koherens tomografi anjiyografinin (OKTA) koryokapillaris kesitinde ise İSYA’daki hiposiyanesan noktalarla uyumlu şekilde siyah nokta şeklinde defektler izlendi. Tüm sistemik muayene ve laboratuvar incelemeleri yapıldı. Toxoplasma gondii serolojisi pozitif bulundu. Hastaya beyaz nokta benzeri koroid tutulumunun eşlik ettiği sağ akut maküler koryoretinit tanısı konuldu. Olguya oral trimetoprim-sülfametoksazol, azitromisin ve steroid tedavisi başlandı. İki hafta sonra tekrarlanan İSYA’da hiposiyanesan noktaların sayıca belirgin şekilde azaldığı görüldü. Bir ay sonraki kontrolde ise görmenin arttığı, maküladaki ana lezyonun aktivitesini yitirdiği, epiretinal bir membran oluşumu olduğu ve OKTA’nın koryokapillaris kesitindeki siyah noktasal değişikliklerin önemli ölçüde azaldığı izlendi. Toksoplazma koryoretinitinde İSYA çekilerek, saptanması zor olan olası koroidal değişikliklerin gösterilmesi mümkün olabilir.
