    (2023) Suzan Doğruya; ozcan kayikcioglu; ismail diri; Muhammed Altinisik; Omer Can Kayikcioglu
    Amaç: Pars plana vitrektomi (PPV) için ameliyathaneye alınan ancak ameliyatı ertelenen hastaların ameliyatlarının ertelenme sebepleri ve bunlara yönelik alınabilecek önlemleri tespit etmek. Gereç ve Yön- temler: Ocak 2018-Haziran 2019 tarihleri arasında farklı retina hasta- lıkları nedeniyle ameliyat edilmesi planlanan ancak t ıbbi nedenlerle ameliyatları iptal edilen 25 hasta bu çalışmaya dahil edildi. Hastaların demografik bilgileri ve ameliyat olma endikasyonları ve ameliyatları- nın ertelenme sebepler i analiz edildi. Bulgular: Hasta grubunda 11’ i (%44) kadın ve 14’ü (%56) erkek ve 15’ inin (%60,2) sa ğ gözünde, 10’unun (%39,8) sol gözünde vitreoretinal cerrahi ihtiyacı vardı. Ame- liyat endikasyonu 8 (%32) hastada d iyabetik intravitreal hemoroji, 7 (%28) hastada retina dekolmanı, 5 (%20) hastada katarakt ve epiretinal membran, 4 (%16) hastada göz içi lens dislokasyonu ve 1 (%4) has- tada retina dekolmanlı prefitizik göz idi. Öz geçm işlerinde 16 (%64) hastada h ipertansiyon (HT), 11 (%44) hastada d iabetes mell itus, 7 (%28) hastada koroner kalp hastal ığı (KKH), 2 (%8) hastada obez ite, 2 (%8) hastada kron ik böbrek yeters izliği ve 1 (%4) hastada ep ilepsi vardı. En çok karşılaşılan ameliyat erteleme sebebi HT ve KKH (%64) idi. Sonuç: Ameliyat erteleme sebepler ini dikkatli şekilde değerlen- dirmek ve daha fazla önlem almak hem hasta hem de sağlık sisteminin zaman ve diğer kayıplarını azaltacaktır.

    Double neovascularization in the same eye with pachychoroid neovasculopathy: one exudative and the other non-exudative
    (2023) Muhammed Altinisik; SELİN DENİZ ORUÇ; Mustafa Erdogan
    Pachychoroid neovasculopathy (PNV) is a pachychoroid spectrum disease characterized by macular neovascularization (MNV), dilated outer choroidal vessels (pachyvessels), and/or increased choroidal thickness. In PNV cases, optical coherence tomography angiography (OCTA) can reveal MNV with high resolution. A 65-year-old male patient was admitted to our clinic with the complaint of decreased vision in the right eye. On dilated fundus examination, retinal pigment epithelium changes were present in the foveal and extrafoveal areas in both eyes. There was subretinal fluid in the fovea and irregular pigment epithelial detachment in the right eye. Subfoveal MNV was detected in 3 × 3 mm sections of OCTA. A non-exudative MNV was also detected in a larger 6 × 6 mm area imaged with OCTA. Simultaneous non-exudative quiescent MNV in the extrafo- veal region of the same eye can be observed. To avoid missing those cases, it is critical to perform OCTA imaging sections, including the extrafoveal areas.

    Pars Plana Vitrectomy for Central Retinal Artery Occlusion Without Emboli
    (2023) Muhammed Altinisik; Emin Kurt; Beyza Tekin Altinbay; ozcan kayikcioglu; Suzan Doğruya
    Purpose: The results of patients who had 23-G pars plana vitrectomy (PPV) unresponsive to medical therapy for central retinal artery occlusion without visible embolization are presented. Materials and Methods: We operated on eight patients who were treated for acute central retinal artery occlusion without visible emboli in our clinic. We started emergency medical treatment following diagnosis which was unsuccessfull. Afterwards, the patient had PPV in six cases and PPV- trabeculectomy in two cases. During the operation we applied intraoperative hypotonia for ten minutes and we tried to restore retinal circulation with fluid turbulance on optic nerve head. While visual acuity remained at the basal level in five patients (hand movement positive), slight increase was observed in three patients (preop P (-), 20 cmFC, 2 mFC, ; postop 30 cmFC, 30 cmFC, 0.1 respectively). Discussion and Conclusion: Primary pars plana vitrectomy and surgical hypotonia may be an early treatment option for central retinal artery occlusion without visible emboli, which should be evaluated in large scale studies.
