Intravitreal bevacizumab therapy for choroidal neovascular membrane secondary to presumed ocular histoplasmosis syndrome

Oküler histoplazmozis genç erişkinlerde ağır görme kaybına yol açabilen bir hastalıktır. Çok sayıda koryoretinal lezyonlar, peripapiller atrofi ve koroidal neovasküler membrana (KNVM) bağlı makülopatisi olan genç hastalarda olası oküler histoplazmozis sendromu (OOHS) akılda tutulmalıdır. Bu yazıda OOHS'a bağlı nüks KNVM gelişen bir hastanın tek doz intravitreal bevacizumab ile tedavisi sunulmuştur.Ocular histoplasmosis is a disease that can lead to severe visual loss in young adults. Presumed ocular histoplasmosis syndrome (POHS) should be kept in mind in younger patients with multiple chorioretinal lesions, peripapillary atrophy and maculopathy caused by choroidal neovascular membrane (CNVM). Here a treatment of recurrent CNVM secondary to POHS with a single dose of intravitreal bevacizumab is presented

The Injection of Air/Oxygen Bubble into the Anterior Chamber of Rabbits as a Treatment for Hyphema in Patients with Sickle Cell Disease

Purpose. To investigate the changes of partial oxygen pressure (PaO2) in aqueous humour after injecting air or oxygen bubble into the anterior chamber in sickle cell hyphema. Methods. Blood samples were taken from the same patient with sickle cell disease. Thirty-two rabbits were divided into 4 groups. In group 1 (n=8), there was no injection. Only blood injection constituted group 2 (n=8), both blood and air bubble injection constituted group 3 (n=8), and both blood and oxygen bubble injection constituted group 4 (n=8). Results. The PaO2 in the aqueous humour after 10 hours from the injections was 78.45 ± 9.9 mmHg (Mean ± SD) for group 1, 73.97 ± 8.86 mmHg for group 2, 123.35 ± 13.6 mmHg for group 3, and 306.47 ± 16.5 mmHg for group 4. There was statistically significant difference between group 1 and group 2, when compared with group 3 and group 4. Conclusions. PaO2 in aqueous humour was increased after injecting air or oxygen bubble into the anterior chamber. We offer to leave an air bubble in the anterior chamber of patients with sickle cell hemoglobinopathies and hyphema undergoing an anterior chamber washout

Investigation of the association between glaucoma and Helicobacter pylori infection using the 14C-urea breath test

ABSTRACTPurpose:To investigate the association between glaucoma and Helicobacter pylori infection by evaluating for the presence of H. pylori infection in patients with glaucoma using the 14C-urea breath test (14C-UBT).Methods:Using 14C-UBT, H. pylori infection positivity was compared between a group of patients with primary open-angle glaucoma and a control group with normal intraocular pressure and a normal optic disc or normal perimetry.Results:The 14C-UBT was positive in 18 (51.42%) out of 35 patients in the glaucoma group and in 15 (42.85%) out of 35 patients in the control group. H. pylori infection positivity rates were similar between the glaucoma and control groups (p>0.05).Conclusion:According to the 14C-UBT, there is no association between primary open-angle glaucoma and H. pylori infection
