Purpose:To conduct an in vitro experimental study comparing the effectiveness of conventional silicone oil and heavy silicone oil against endophthalmitis-causing agents.Materials and Methods:The antimicrobial activity of conventional silicone oil (RS OIL 5000) and heavy silicone oil (heavySil 1500) was tested. The antimicrobial effects of both silicone oils were determined by the growing capability of the microorganism.Results:The number of Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli, Pseudomonas aeruginosa, and Candida albicans decreased to zero levels at the second day of inoculation in heavy silicone oil. In conventional silicone oil, the microorganisms survived longer than in heavy silicone oil.Conclusion:Heavy silicone oil seems to be more effective than conventional silicone oil against endophthalmitis-causing agents.

Purpose To investigate the rate of neodymium-doped yttrium aluminum garnet (Nd:YAG) laser capsulotomy in the hydroimplantation intraocular lens (IOL) technique. Methods This retrospective study was comprised of 6,192 eyes in 3,790 patients who underwent surgery from January 2013 to September 2017 and then were followed up for at least 1 year. The eyes of these patients were divided into two groups: either viscoimplantation or hydroimplantation. The follow-up examinations were carried out on the 1st day, 4th day, 1st month, and 3 months to 1 year postoperatively. The Nd:YAG capsulotomy rates were evaluated by the different IOL implantation techniques and IOL materials. Results The mean follow-up duration of the patients was in the viscoimplantation group 14.85 ± 2.43 and 15.05 ± 1.93 months in the hydroimplantation group. The Nd:YAG capsulotomy rate was significantly lower in the hydroimplantation group compared with the viscoimplantation group for the entire hydrophilic IOL model ( p < 0.001). In addition, the Nd:YAG rate was lower in the hydroimplantation group that used a hydrophilic IOL than it was in the viscoimplantation group, which used a hydrophobic IOL. Conclusions The hydroimplantation technique reduced the Nd:YAG capsulotomy rate.

The aim of this study was to evaluate plasma adropin levels in patients with pseudoexfoliation (PEX). This retrospective case-control study included 35 patients with PEX and 35 individuals without PEX who served as controls. Plasma adropin levels with triglycerides, total cholesterol, low-density lipoprotein (LDL), high-density lipoprotein (HDL), and haemoglobin A1c (HGBA1C) concentrations were measured in both groups. The mean serum adropin levels were 3.24 ± 0.95 ng/mL (range, 1.90-7.88 ng/mL) in patients with PEX syndrome and 5.78 ± 2.85 ng/mL (range, 2.08-5.41 ng/mL) in PEX glaucoma patients. There was no statistically significant difference in mean adropin levels between PEX syndrome and PEX glaucoma patients. However, similar adropin levels were found in the PEX glaucoma patients and the control group (P > 0.05). The mean serum adropin levels were 3.34 ± 0.89 ng/mL (range, 1.90-5.39 ng/mL) in the PEX group and 5.78 ± 2.85 ng/mL (range, 3.08-11.06 ng/mL) in the control group. The mean serum adropin level of the PEX group was significantly lower than that of the control group (P < 0.001). There were no significant differences between the two groups in terms of serum glucose, total cholesterol, LDL, HDL, HGBA1C, triglycerides levels, or body mass index (all P > 0.05). Adropin level is lower in patients with PEX.

The aim of this stuty is to describe a case of endophthalmitis after tooth extraction in a patient with previous perforating eye injury. 50 years old male patient attempted to our clinic with complaints of sudden severe pain, reduced vision, light sensitivity and redness in the right eye. The patient stated that severe pain in his eye began approximately 12 hours following tooth extraction. The patient's ocular examination revealed a visual acuity of hand motion in the right eye. Anterior segment examination of the right eye showed intense conjunctival hyperemia, chemosis, a fine keraticprespitat and corneal edema. Dental procedures of the patients who had recently underwent ocular surgery or trauma should be done in a more controlled manner under anti -infective therapy or should be postponed in elective procedures.

Amaç: Topikal antiglokomatöz ilaç kullanan glokom hastalarında oküler yüzey hastalığını (OYH) değerlendirmek. Hastalar ve Yöntem: Çalışmaya farklı formlarda glokom tanısı alan ve en az 6 aydır glokom ilacı kullanan 18 yaş üstü 83 hasta dahil edildi. Oküler yüzey hastalık endeks(OSDI) anketi hastalara tek tek sorularak dolduruldu. Sonrasında hastalarda oküler yüzeyi klinik olarak değerlendirmek için schirmer testi (anestezili), gözyaşı kırılma zamanı(GKZ) ve korneal boyanmaya bakıldı. Bulgular: Çalışmaya 51 erkek 32 kadın toplam 83 hastanın 159 gözü dahil edildi. Erkeklerin yaş ortalaması 64,51±9,07 bayanların yaş ortalaması 54,32±11,44 idi. Hastaların ortalama ilaç kullanım süreleri 6,35±5,63 yıldı. Hastaların %36,5'i tek ilaç ,%32,1'i iki ilaç, %13,8'i üç ilaç ve %17,6'sı dört ilaç kullanmaktaydı. OSDI anketi kullanılarak kuru göz semptomları değerlendirilen hastaların %3,8'i normal, % 15,7'si hafif, %22,6'sı orta ve %57,9 şiddetli kuru göz hastası olarak değerlendirildi. Tüm hastaların ortalama OSDI skoru 46,80±19,44'tü. Schirmer testi gözlerin %34,1'inde 5 mm'nin altında saptandı. GKZ gözlerin % 52,3'de hafif,%29,5'de orta, %8,5,de şiddetli olarak değerlendirildi. Korneal boyanma açısından değerlendirildiğinde ise gözlerin %13,2'da normal boyanma, %39,6'de hafif boyanma, %23,3'de orta derecede boyanma ve %23,9'da ise şiddetli boyanma mevcuttu. Sonuç: OYH'nın teşhis edilmesinde, OSDI anketinin yanı sıra gözyaşı kalitesini ve stabilitesini gösteren testleri de içeren bir değerlendirmenin yapılması daha sağlıklı olacaktır.
