conferenceObject OPTIC COHERENCE TOMOGRAPHY FEATURES OF SUBRETINAL VITREOUS SUBSTITUTES(2017) ZACHARIAS, Leandro C.; CARVALHO, Jose Ronaldo Lima; SILVA, Epitacio Dias da; TANAKA, Tatiana; PRETI, Rony C.; TAKAHASHI, Walter; CUNHA, Leonardo Provetti; MONTEIRO, Mario R.- Case report: pneumatic retinopexy for the treatment of progressive retinal detachment in senile retinoschisis(2015) SUZUKI, Ana Claudia de F.; ZACHARIAS, Leandro Cabral; TANAKA, Tatiana; ROCHA, Diego Neves; TAKAHASHI, Walter Y.Retinoschisis is an abnormal separation of the retinal layers and is asymptomatic in most cases. Enlargement of the area of retinoschisis and retinal tear and detachment are possible complications of the disease, and the treatment of retinoschisis is controversial. In this case report, we present a case of retinal detachment associated with senile retinoschisis in which pneumatic retinopexy was chosen as the treatment of choice and was performed successfully in one of the eyes. After a literature review on retinoschisis and pneumatic retinopexy for the treatment of associated retinal detachment, we found only one case that was successfully treated without drainage of subretinal fluid, using air as the filler. However, no previous reports have been found in the literature on the effectiveness of pneumatic retinopexy using C3F8 as the sole treatment for progressive retinal detachment in senile retinoschisis.
- Optic coherence tomography features of subretinal vitreous substitutes(2020) ZACHARIAS, Leandro Cabral; SILVA NETO, Epitacio Dias da; RODRIGUES NETO, Taurino dos Santos; CARVALHO JUNIOR, Jose Ronaldo Lima de; PRETI, Rony Carlos; CUNHA, Leonardo Provetti; TANAKA, Tatiana; MONTEIRO, Mario Luiz RibeiroBackgroundTo draw comparisons between spectral domain optic coherence tomography (SD-OCT) features of subretinal silicon oil (SO), perfluoro-n-octane (PFO) or C3F8 gas.MethodsCases diagnosed with retained subretinal vitreous substitutes (VS) were retrospectively selected. Demographic data were collected and OCT features were analyzed.ResultsIn the 13 cases with subretinal PFO, hyper-reflectivity under the bubble was noted in 8 eyes (61.5%); choroidal shadow at the borders of the bubble in 11 eyes (84.6%); hyper-reflective halo around the bubble in 5 eyes (38.4%) and a hyper-reflective apical dot in 8 eyes (61.5%).The two cases with multiple PFO bubbles had complete septum dividing the bubbles. The one case with subretinal SO had hyper reflectivity under the bubble; no choroidal shadow at the edge of the bubble; hyper-reflective halo was noted around the bubble and the apical hyper-reflective dot was present; there was no complete septum dividing multiple bubbles. The single case with subretinal C3F8 had some bubbles with totally round base, incomplete septum, hyper reflectivity under the bubble, choroidal shadow at the edge of the bubble, a hyper-reflective halo and an apical dot.ConclusionDifferent subretinal VS share similar SD-OCT characteristics. Round base bubbles are only observed with subretinal C3F8 gas, while incomplete septum are related to retained subretinal SO or gas.
- Socioeconomic Barriers to Rhegmatogenous Detachment Surgery in Brazil(2014) CARRICONDO, Pedro Carlos; TANAKA, Tatiana; SHIBATA, Suellen Tiemi; ZACHARIAS, Leandro Cabral; LEITE, Thiago Aragao; ABALEM, Maria Fernanda; TAKAHASHI, Walter Y.Purpose. To verify access barriers patients with retinal detachment face to arrive at a reference center and to evaluate patients' knowledge about the disease. Methods. Transversal study that applied a questioner to 65 patients of the Clinical Hospital of the University of Sao Paulo with retinal detachment between February and August of 2010. Results. Reasons for not performing the surgery in other services were as follows: 47% were referred because there was not vitreoretinal surgeon at original service; 27% could not afford the surgery, had no health insurance, or had no coverage at health insurance plan for the procedure. Time between the first symptom and the arrival at our service was as follows: 18 patients arrived in up to 7 days; 35 between 8 and 30 days; 8 between 31 and 90 days; 5 in more than 90 days. Reasons for delay were as follows: 70% did not know how serious the pathology was; 56% thought that it had spontaneous cure; 16% did not have money to pay for ophthalmic evaluation, 10% did not know where to go and 24% for other reasons. Conclusion. Educational programs about disease and measures to optimize the referral to specialized services are needed to accelerate the treatment of patients with rhegmatogenous retinal detachment.
