Öğe Anti-demodex effect of commercial eyelid hygiene products(Taylor and Francis Ltd., 2021) Bulut, Asker; Tanrıverdi, CaferPurpose To investigate in vitro effects of active ingredients in eye cleansing wipes and solutions on the life span of Demodex. Methods Demodex mites were extracted by eyelash epilation method from volunteers who were found to have chronic demodex blepharitis during an ophthalmological examination. Preparations with three or more motile, live adult Demodex parasites were included in the study. Two drops of the test solution were dropped on the samples: saline, 2% tea tree oil (TTO; Osto (R), AKD Medical products, Turkey), 7.5% TTO (Blefaritto (R), Jeomed, Turkey), and 0.5% terpinen-4-ol (T4O; Blefastop plus (R), NTC, Italy). Under light microscopy at 100x and 400x magnification, samples were examined and followed. The average killing time of Demodex was noted for each preparation. Results The study was analyzed on 120 patient samples. In the control group with saline, the average killing time of Demodex had an average of 323.5 +/- 21.1 min. In other groups, an average mean of 95.9 +/- 25.2 min in the 2% TTO group, 67.1 +/- 21.8 min in the 7.5% TTO group, and 27.3 +/- 6.0 min in the 0.5% T4O group was observed. It was found that the 0.5% T4O group was significantly more effective than the other groups. Conclusion Chronic Demodex blepharitis treatment is quite difficult in ophthalmology practice. It appears that, even at very low concentrations, T4O has an effective anti-Demodex effect.Öğe Comparison of phacoemulsification parameters using active fluidic pressure control system versus gravity-fluidic syste(Kare Publishing, 2021) Bulut, AskerObjectives: This study aimed to compare the mean surgical time, cumulative dissipated energy (CDE), aspiration timeand estimated aspiration fluid parameters in phacoemulsification surgery using an active-fluidic pressure control sys tem (AFPCS) in comparison with gravity-fluidic system (GFS). Methods: The study analysed 202 eyes of 202 patients diagnosed with senile nuclear cataract and admitted to ourclinic. Phacoemulsification surgery was performed by an experienced surgeon using the Centurion Vision System de vice and the Infiniti Vision System device. After each case, the mean surgical time, CDE, aspiration time and estimatedaspiration fluid parameters were recorded. Complicated cases were excluded from the study. Results: In the AFPCS group, the mean age of the patients was 64.15±3.83 years, with the following results: mean surgi cal time, 11.88±5.44 min; CDE, 11.63±9.37; aspiration time, 3.91±1.49 min; estimated aspiration fluid, 71.89±27.56 ml. Inthe GFS group, the mean age of the patients was 64.99±3.80 years, and the following results were obtained: mean sur gical time, 14.35±3.93 min; CDE, 13.60±7.61; aspiration time, 5.56±1.8 min; estimated aspiration fluid, 101.23±15.62 ml. Conclusion: AFPCS was found to be more successful than GFS, with low-energy consumption, shorter surgical timeand better postoperative outcomes.Öğe Edinilmiş nazolakrimal kanal tıkanıklığı tedavisinde transkanaliküler multidiod lazer dakriyosistorinostomi sonuçları(2019) Bulut, Asker; Öner, VeysiAmaç: Edinilmiş primer nazolakrimal kanal tıkanıklığı tedavisinde transkanaliküler multidiod lazer dakriyosistorinostomi ameliyat sonuçlarının değerlendirilmesi.Gereç ve Yöntem: Bu retrospektif çalışmaya, epifora şikayeti ile başvuran ve muayenede ortak kanalikülün distalinde tıkanıklık tespit edilerek transkanaliküler multidiod lazer dakriyosistorinostomi cerrahisi ve bikanaliküler silikon tüp yerleştirilmesi ameliyatı uygulanan hastalar dahil edildi. Postoperatif dönemde yapılan kontrollerde pasajın açık olup olmadığı nazolakrimal kanal lavajı ile kontrol edilip semptom ve bulgulardaki değişiklikler sorgulandı. Tüplerin çıkarılma süreleri ayrıca kaydedildi.Bulgular: Transkanaliküler multidiod lazer dakriyosistorinostomi uygulanan toplam 49 hastanın 35’i kadın 14’ü erkekti. 49 hastanın 50 gözüne transkanaliküler multidiod lazer dakriyosistorinostomi cerrahisi ve bilateral silikon tüp entübasyonu yapıldı. Hastaların yaş ortalaması 50.00±14.299 yıl idi. Ortalama takip süresi 14.08±7.042 ay idi. Slikon tüplerin çıkarılma süreleri ortalama 3.42±0.906 ay idi.Takip sonrası 49 hastada başarı oranı %56 (28/50) olarak saptandı.Sonuç: Transkanaliküler multidiod lazer dakriyosistorinostomi ameliyatı estetikliği, kolaylığı, hızlı ve tekrarlanabilirliği yönü ile cazip görünse de cerrahi başarı oranı istenilen düzeyde çıkmamıştır.Öğe Static and dynamic pupillometry changes after uneventful phacoemulsification surgery(Gazi Eye Foundation, 2022) Bulut, Asker; Bayat, Alper HalilPurpose: To compare postoperative changes in static and dynamic pupil size after uneventful phacoemulsification surgery. Materials and Methods: 70 eyes of seventy patients (34 women and 36 men), who underwent phacoemulcification surgery were included in the study. Static and dynamic pupillometry measurements were examined and recorded in patients who were diagnosed with cataract and planned for surgery in the preoperative period without using mydriatic drops. Follow up controls were examined on the 1st day, 1st week and 1st month after cataract surgery. Pupillometry measurements were examined again in the examination at the 1st month control. The Aladdin® (Topcon, Tokyo, Japan) system was used for the measurement of pupillometry. Preop and postop first month pupillometry measurements were recorded and compared. Results: The minimum value of dynamic PD was 3.29±0.94 mm before cataract surgery, which decreased to 3±0.86 mm after cataract surgery (p = 0.016). The maximum value of dynamic PD was 4.12±0.84 mm before cataract surgery, which decreased to 3.88±0.73 mm after cataract surgery (p = 0.01). Mesopic PD was 3.75±0.83 mm before cataract surgery, and it decreased to 3.41±0.59 mm after cataract surgery (p < 0.001). Photopic PD was 3.22±0.73 mm before cataract surgery, and it decreased to 2.82±0.63 mm after cataract surgery (p < 0.001). Conclusion: Phacoemulsification surgery changes the static and dynamic PD due to possible changes in ACD, postoperative anterior chamber reaction and topical drops used.Öğe Transcanalicular multidiode laser versus external dacryocystorhinostomy in the treatment of acquired nasolacrimal duct obstruction(2021) Bulut, Asker; Aslan, Mehmet Gökhan; Öner, VeysiObjectives: This study was a comparison of the outcomes of transcanalicular multidiode laser dacryocystorhinostomy (TCLDCR) and external dacryocystorhinostomy (EXDCR) treatment for patients with acquired nasolacrimal duct obstruction. Methods: Thirty-one consecutive patients who underwent TCLDCR (TCLDCR group) and 68 consecutive patients who underwent EXDCR (EXDCR group) due to acquired nasolacrimal duct obstruction were enrolled in the study. Follow-up visits were performed on the first day, and at the first week, first month, third month, sixth month, and every six months thereafter. Surgical success was defined as achievement of a patent osteotomy and a successful bicanalicular silicone intubation during the procedure. Anatomical success was defined by observation of a patent osteotomy on lacrimal irrigation, regardless of epiphora. The surgery time and intra- and postoperative complications were noted for each patient. Results: The TCLDCR group had a significantly shorter mean surgery time (27.9±5.5 minutes) compared with the EXDCR group (58.5±12.0 minutes) (p<0.001). However, the mean anatomical and functional rates of TCLDCR (58.0% and 54.8%, respectively) were significantly lower than those of the EXDCR group (94.1% and 91.1%, respectively) (both p<0.001). Two patients had "cheese wiring" damage of the lower canaliculus and 1 patient in the TCLDCR group had a full-thickness skin defect in the medial canthal region. No serious intra- or postoperative complication occurred in the EXDCR group. Conclusion: Although a TCLDCR procedure decreased the surgical time, it had a significantly lower success rate in the treatment of acquired nasolacrimal duct obstruction compared to EXDCR. The decision of the type of surgery should be made based on the cosmetic and success expectations of the patients and the presence of systemic problems.
