Publication Evaluation of intraocular pressure change and anterior segment parameters after intravitreal bevacizumab injection - cannula size matters(Wolters Kluwer Medknow Publications, 2020-10-01) Hamidi, Nagihan A.; Güneş, Irfan B.; Baykara, Mehmet; Baykara, Mehmet; BAYKARA, MEHMET; Bursa Uludağ Üniversitesi/Tıp Fakültesi/OftalmolojiAnabilim Dalı.; ABI-7051-2020PURPOSE: To determine the changes in intraocular pressure (IOP) and anterior chamber parameters following intravitreal bevacizumab injection with different sizes of cannulas. METHODS: This clinical trial was conducted with 70 eyes of 70 patients who received an intravitreal injection of bevacizumab with 26 G (Group 1) or 30 G (Group 2) needle. Preinjection and postinjection 30th-min IOP and pentacam measurements were obtained. Anterior chamber depth (ACD), anterior chamber volume (ACV), central corneal thickness (CCT), corneal volume (CV), and iridocorneal angle (ICA) measurements were evaluated in pentacam. RESULTS: Preinjection mean IOP values in Group 1 and 2 were 14.7 +/- 3.29 mm Hg and 15.1 +/- 2.87 mm Hg, respectively. Postinjection mean IOP in Group 1 was 16.8 +/- 6.24 mm Hg and in Group 2 was 20.3 +/- 3.66 mm Hg. Postinjection mean IOP values were significantly higher than preinjection values in both groups (Group 1 P < 0.005 and Group 2 P < 0.001). IOP change was significantly higher in Group 2 after injection (P < 0.05). In both groups, the change in IOP found to be more significant in phakic eyes than pseudophakic eyes (Group 1 P < 0.001, Group 2 P < 0.001). CCT and CV were significantly higher in both groups 30 min after the injection than preinjection (Group 1 and Group 2; P < 0.01). In Group 2 ACD, ACV and ICA values were significantly lower than preinjection values (P < 0.05). CONCLUSION: Needle bore size is an important parameter that influences anterior segment parameters and IOP change in the intravitreal injection. IOP rise and anterior segment changes are more prominent with a thinner cannula.Publication Acanthamoeba keratitis and acanthamoeba conjunctivitis: A case report(Iranian Scientific Society Medical Entomology, 2020-04-01) Alver, Oktay; Baykara, Mehmet; Yuruk, Merve; Ülkü Tüzemen, Nazmiye; ALVER, OKTAY; BAYKARA, MEHMET; TÜZEMEN, NAZMİYE ÜLKÜ; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Tıbbi Mikrobiyoloji Anabilim Dalı; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Göz Hastalıkları Anabilim Dalı; 0000-0002-5555-1649; AAA-5241-2021; ABI-7051-2020; CGE-2103-2022Acanthamoeba species are vision-threatening agents by causing cornea infections known as Acanthamoeba keratitis. A 5 year-old kid with the complaints of erythema, eyelid edema, inflammation, limitation of eye movements in the right eye, and having no history of wearing contact lenses or trauma, was diagnosed of Acanthamoeba conjunctivitis through laboratory examinations in the Ophthalmology clinic. The visual sharpness of the patient improved after the treatment. A 44 year-old female patient suffering from pain, stinging, irritation, and inability to see in the left eye with the history of wearing contact lenses or trauma was diagnosed of Acanthamoeba keratitis through laboratory examinations. The agent was isolated and identified as "A. castellam" in the Genotype "T2". Examination of the left eye on the 15th day of treatment indicated that all complaints disappeared except for the cataract originated visual loss. However, the first diagnosis of Acanthamoeba keratitis appeared in the literature on a case with no history of wearing contact lenses and trauma it is found to be attention grabbing. We think that Acanthamoeba should not be ignored among microbial agents that cause eye infection with or without trauma and contact lens usage history.Publication Evaluation of the cataract surgery 2018 survey in terms of achieving refractive cataract surgery targets(Turkish Ophthalmological, 2021-01-01) Can, Izzet; Takmaz, Tamer; Ozdamar, Akif; Kamis, Umit; Akova, Yonca Aydin; Arslan, Osman Sevki; Devranoglu, Kazim; Gunenc, Uzeyir; Mutlu, Fatih Mehmet; Ozcan, Altan Atakan; Tasindi, Emrullah; Baykara, Mehmet; BAYKARA, MEHMET; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Oftalmoloji Anabilim Dalı.; 0000-0001-9494-8756; 0000-0001-6359-4799; 0000-0002-5555-1649; 0000-0003-0504-0370; 0000-0002-7796-6511; AAT-6236-2020; F-1103-2018; ABI-7051-2020Objectives: The aim of this study was to show at what rate the technological equipment used in cataract surgery by Turkish ophthalmologists and their knowledge are reflected in practice and how up to date they are.Materials and Methods: A questionnaire conducted using SurveyMonkey was used to evaluate the answers to 17 questions from 823 members of the Turkish Ophthalmological Association. Results were evaluated in subgroups according to the participants' age, occupational status, institutions, and whether they conducted relevant academic activities, and the data were compared as inadequate, standard, and contemporary approaches according to the determined criteria.Results: Optical biometry devices were used at rates of 77.7% and 67.3% for intraocular lens (IOL) power calculations and keratometric measurements in preparation for cataract surgery, respectively. For IOL power calculation, third-generation formulas, especially the SRK-T, were used most commonly (46.2%), followed by second-generation formulas (21.9%), and fourth/fifth-generation formulas and multiple evaluations for different axial lengths (31.9%). The most common incision size was 2.8 mm (51.6%), while the percentage of 2.2 mm and shorter incisions considered to be neutral in terms of surgically induced astigmatism was 18.8%. When selecting incision location, approaches to reduce corneal astigmatism were reported by 28.9%, neutral approaches by 26.2%, and insensitive approaches by 44.9%. Additionally, 55.6% of participants never implanted toric IOLs and 50.7% did not use presbyopia-correcting IOLs. The proportion of surgeons who have experience with femtosecond laser-assisted cataract surgery was 10.3% and the rate of intracameral antibiotic injection at the end of the operation was 89.4%.Conclusion: It was seen that Turkish cataract surgeons were able to use high technology for surgical preparation and surgery at high rates, but this was not reflected in practice at same rate in terms of achieving contemporary standards of refractive cataract surgery.
