ABSTRACT
OBJECTIVES: The objective of this study was to evaluate the relationship between the treatment of Helicobacter pylori gastric infection and changes in best-corrected visual acuity and macular detachment in patients with chronic central serous chorioretinopathy. METHODS: Seventeen patients diagnosed with central serous chorioretinopathy were examined for gastric infection with Helicobacter pylori using the urease test and gastric biopsy. Helicobacter pylory-positive patients were treated with the appropriate medication. The response to therapy was monitored by evaluating the best-corrected visual acuity and optical coherence tomography. The data were analyzed using Student's t-test before and after treatment. RESULTS: Fourteen patients (15 eyes) aged 30-56 years (mean 43.4 ± 8.3 years) were positive for Helicobacter pylori. Most of the positive patients had gastric symptoms (78.5%); one had bilateral central serous chorioretinopathy. The mean baseline best-corrected visual acuity was 20/98 (logMAR = 0.53 ± 0.28). Three months after starting treatment with antibiotics, the serous detachment had resolved in 14 of 15 eyes, but two cases required laser treatment. The follow-up period ranged from 6 to 27 months. The mean final best-corrected visual acuity differed significantly from baseline. CONCLUSION: Our findings suggest that Helicobacter pylori infection may be present in many chronic central serous chorioretinopathy patients and that treatment for the infection may have a favorable effect on the outcome of chronic central serous chorioretinopathy. Due to the possibility of the spontaneous regression of chronic central serous chorioretinopathy and the high prevalence of the infection in the general population, prospective and masked clinical trials are necessary to confirm that treatment for Helicobacter pylori infection may benefit patients with chronic central serous chorioretinopathy.

O objetivo desta série de casos foi demonstrar se a aplicação de bevacizumab e gás perfluoropropano (C3F8) intravítreos beneficiariam o deslocamento da hemorragia sub-retiniana dos pacientes com degeneração macular relacionada à idade. Foi realizada uma série retrospectiva de 5 olhos que tinham recebido injeção intravítrea simultânea de bevacizumab e C3F8. Os resultados foram medidos pelo grau de deslocamento de sangue sob a fóvea, pela acuidade visual final e pelas complicações intraoperatórias. Na apresentação inicial, a idade média dos pacientes foi de 72,6 ± 8,9 anos e a duração média dos sintomas foi de 13 ± 9,7 dias. Dos 5 pacientes do estudo, 3 (60 por cento) eram homens e 2 (40 por cento) mulheres. O sucesso do deslocamento da hemorragia submacular foi alcançado em 4 pacientes. A média de acuidade visual pré-operatória foi de 1,12 ± 0,34 logMAR e pós-operatório foi de 0,92 ± 0,4 logMAR. Não foram observados nenhum caso de descolamento da retina, endoftalmite, hemorragia vítrea, uveíte, catarata e hipertensão ocular. A injeção intravítrea bevacizumab e C3F8, juntamente com a posição pronada pode ser uma valiosa opção terapêutica nos olhos com degeneração macular relacionada à idade neovascular e hemorragia sub-retiniana a fim de deslocar o sangue para fora da área foveal.
The purpose of this case series is to describe if the intravitreal use of bevacizumab and perfluoropropane gas (C3F8) would be beneficial to the displacement of subretinal hemorrhage in patients with age-related macular degeneration (AMD). A retrospective study of 5 eyes that received concurrent intravitreal injection of bevacizumab and C3F8 was performed. The results were graded according to blood displacement under the fovea, best final visual acuity and intraoperative complications. At the initial presentation, mean age of patients was 72.6 ± 8.9 years-old and duration of symptoms was 13 ± 9.7 days. From the 5 patients, 3 (60 percent) were male and 2 (40 percent) female. The success of submacular hemorrhage full displacement was achieved in 4 patients. The mean preoperative visual acuity (VA) was 1.12 ± 0.34 logMAR and the mean postoperative VA was 0.92 ± 0.4 logMAR. No cases of retinal detachment, endophthalmitis, vitreous hemorrhage, uveitis, cataracts and increased intraocular pressure were noted during the follow-up period. Intravitreal bevacizumab and C3F8 injection, associated to prone position can be a valuable therapeutic option for eyes with neovascular age-related macular degeneration and subretinal hemorrhage to the blood displacement out of the foveal area.
