          Abstract

          OBJECTIVE: To observe the effectiveness of intravenous sodium fluorescein visibility in the vitreous during vitrectomy surgery in patients with diabetic retinopathy. METHODS: Fourteen consecutive cases of vitreoretinal surgery for vitreous hemorrhage and tractional retinal detachment secondary to diabetic retinopathy underwent intravenous injection of sodium fluorescein to 20% 1 hour before the surgery. The images of the steps of the surgeries were recorded. RESULTS: The sodium fluorescein stained green from the vitreous peripheral, vitreous base, posterior hyaloid, further improving visibility to a complete and more secure vitrectomy. The sodium fluorescein also stained fibrous points (sites of neovascularization) with high intensity making it easier its visibility. No complications associated with the dye injection were observed in all cases. CONCLUSION: Intravenous sodium fluorescein can be used safely for facilitating the observation of the vitreous, vitreous base, posterior hyaloid and sites of neovascularization. This technique can facilitate the process of vitrectomy in patients with diabetic retinopathy.

          OBJETIVO: Observar a eficácia da fluoresceína sódica intravenosa, na visibilidade do vítreo, durante a cirurgia de vitrectomia nos pacientes com retinopatia diabética. MÉTODOS: Quatorze casos consecutivos de cirurgia vitreorretiniana para hemorragia vítrea e descolamento tracional da retina secundário à retinopatia diabética, foram submetidos à injeção de fluoresceína intravenosa a 20%, 1 hora antes da cirurgia.As imagens de todos os passos das cirurgias foram gravadas. RESULTADOS: A fluoresceína corou de verde o vítreo periférico, base vítrea, hialóide posterior melhorando a visibilidade para uma vitrectomia completa e mais segura. A fluoresceína também corou pontos fibrosos (sítios de neovascularização) com alta intensidade tornando mais fácil sua observação. Nenhuma complicação associada com a injeção do contraste foi observada. CONCLUSÃO: Fluoresceína sódica intravenosa pode ser usada de forma segura para facilitar a observação do vítreo, base vítrea, hialóide posterior e sítios de neovascularização. Esta técnica pode facilitar o procedimento de vitrectomia em pacientes com retinopatia diabética.

          Vital dyes for chromovitrectomy.

          The aim of this article is to present the current state-of-the-art in regard to the application of vital dyes during vitreoretinal surgery, 'chromovitrectomy', as well as to overview the current literature regarding the properties of dyes, techniques of application, indications, and complications in chromovitrectomy. A large body of published research has recently addressed the toxicity profile of indocyanine green for chromovitrectomy. Experimental data demonstrate dose-dependent toxicity of indocyanine green to various retinal cells. Newer generation vital dyes for chromovitrectomy include trypan blue, patent blue, triamcinolone acetonide, infracyanine green, sodium fluorescein, bromophenol blue, fluorometholone acetate and brilliant blue. Novel instruments may enable a selective painting of preretinal tissues during chromovitrectomy. This review suggests that the field of chromovitrectomy represents an expanding area of research. The first line agents for internal limiting membrane staining in chromovitrectomy are indocyanine green, infracyanine green, and brilliant blue. Patent blue, bromophenol blue and trypan blue arose as outstanding biostains for visualization of epiretinal membranes. Novel dyes available for chromovitrectomy deserve further investigation.

            Morphologic and clinical effects of subretinal injection of indocyanine green and infracyanine green in rabbits.

            The aim of this study was to determine the effects of subretinal injection of indocyanine green (ICG), infracyanine (IfCG), and balanced salt solution (BSS) in rabbits. Ten (10) animals were subjected to a subretinal injection of 0.05% ICG (279 mOsm), 0.5% IfCG (276 mOsm), and BSS (300 mOsm) used as a control. Animals were examined at 6, 12, and 24 h and 14 days following the surgical procedure by indirect binocular ophthalmoscopy, fluorescein angiography (FA), and light and transmission electron microscopy. The subretinal injection of ICG caused damage to all retinal layers and retinal pigment epithelium (RPE) during the entire follow-up. Subretinal injection of IfCG resulted in abnormalities of the photoreceptor outer segments (POSs) during the entire follow-up; however, abnormalities of the photoreceptor inner segments (PISs) and outer nuclear layer (ONL) were observed only 24 h and 14 days after surgery; no RPE damage was observed. FA showed that window defects were more prominent in the subretinal ICG bleb position than the IfCG-related area. BSS caused only abnormalities of the POS layer and no RPE alterations. Subretinal injection of 0.05% ICG results in more significant retinal damage than 0.5% IfCG. In this model, iodine-free IfCG demonstrates a safer profile than a tenfold lower concentration of ICG, which contains iodine in its composition.

              Effect of pars plana vitrectomy for proliferative diabetic vitreoretinopathy on preexisting diabetic maculopathy.

              Vitrectomy is the treatment of choice for proliferative diabetic vitreoretinopathy with tractions and persistent vitreous hemorrhage. Since vitrectomy has recently been discussed as a possible therapy for diabetic maculopathy as well, we were especially interested in studying the change in diabetic maculopathy following surgery. For that purpose a grading system developed at our clinic was used.
