PURPOSE: To evaluate anatomical and functional results of 25-gauge transconjunctival sutureless pars plana vitrectomy in patients with uveitis. METHODS: Vitrectomy was performed on 20 eyes with residual vitritis secondary to infectious and noninfectious uveitis. Patients were evaluated 1 week before surgery and after surgery at day 1, week 1, week 4 and week 12. Visual acuity (VA), intraocular pressure, anterior chamber cells and flare and vitreous haze were measured. RESULTS: Mean VA improved from 2.06 ± 0.94 logMAR before surgery to 0.58 ± 0.46 logMAR at week 12 (p<0.05). No case required conversion to standard 20-gauge instrumentation or suture placement, no intraoperative complications were noted. Transient postoperative hypotony was seen in three eyes. One patient with toxoplasmic retinochoroiditis had a relapse during follow-up. CONCLUSION: 25-gauge vitrectomy has proven its efficacy on cleansing vitreous opacities and improving visual acuity on patients with residual vitritis secondary to uveitis with minimal postoperative inflammation and complications.
OBJETIVO: Avaliar os resultados anatômicos e funcionais da vitrectomia via pars plana 25-gauge transconjuntival sem sutura em pacientes com uveítes. MÉTODOS: Realizou-se vitrectomia em 20 olhos com vitreíte residual secundária a uveíte infecciosa e não infecciosa. Os pacientes foram avaliados uma semana antes e após a cirurgia, no primeiro dia, 1ª, 4ª e 12ª semana. Acuidade visual (AV), pressão intraocular, células e "flare" na câmara anterior e "haze" vítreo foram medidos. RESULTADOS: A AV média melhorou de 2,06 ± 0,94 logMAR antes da cirurgia para 0,58 ± 0,46 logMAR na 12ª semana (p<0,05). Nenhum caso necessitou de conversão para instrumentos de 20-gauge ou realização de sutura e não foram observadas complicações intraoperatórias. Hipotonia transitória foi observada em três olhos. Um paciente com retinocoroidite por toxoplasmose teve recidiva durante o acompanhamento. CONCLUSÃO: Vitrectomia 25-gauge provou sua eficácia na remoção do vítreo opacificado e na melhora da AV em pacientes com vitreíte residual secundária a uveítes, com mínima inflamação pós-operatória e complicações.

Surgical resection of uveal melanomas is an alternative eye-salvaging approach to the more commonly used irradiation techniques. There are two surgical resection techniques: Transscleral resection or "Exoresection" via a partial lamellar sclerouvectomy and "Endoresection" via a pars plana vitrectomy. While exoresection is more applicable to anteriorly located tumors with ciliary body and/or iris involvement, endoresection is more suitable for posteriorly located tumor without ciliary body involvement. Both approaches are suitable for large tumors with >8 mm in thickness. In general, eyes containing these large tumors have a very dismal prognosis regarding long-term visual function, eye retention, and irradiation-induced side effects. By removing the tumor burden from the eye, histopathologic and cytogenetic information of the tumor is available and complications associated with the so-called toxic tumor syndrome are avoided. However, both types of surgical resection are challenging surgical procedures, bearing the risk of early and late postoperative complications
