ABSTRACT We propose a novel surgical technique in cases of aggressive recurrent pterygium non-subsidiary of treatment with conjunctival autografts or antimetabolites. Two presented cases were treated with surgical excision and a sutured plasma rich in growth factors membrane (mPRGF) followed by rich in growth factors (PRGF) eye drops treatment. After surgery, dexamethasone, tobramycin and PRGF eye drops were prescribed for 6 weeks. After a 12-month and 3-year post-surgical follow-up respectively, treated eyes with mPRGF did not present relapse, and visual […]

The orbital pseudotumor is a benign idiopathic inflammatory disease. The authors present a case manifested in 12 years old boy, diagnosed by clinical, laboratory and radiological examination. There was a good response to treatment with corticosteroids proposed. The report is followed by brief literary resume on the subject.

Pterygia are usually benign lesions that do not require specific treatment. It is a fibrovascular growth onto the nasal side of the cornea. It`s cause has not been fully elucidated yet, but seems to be related to long -term ultraviolet ray exposure. When symptoms are not controlled with conservative treatment surgery is considered, but the recurrence rate is still high, and efforts have been made to avoid it. Mitomycin C (MMC) is a fibroblast proliferation inhibitor that can be used […]

Objetivo: Avaliar os resultados de uma abordagem cirúrgica alternativa na excisão de pterígio primário por meio da observação das taxas de recidiva e de complicações intraoperatórias e pós-operatórias Métodos: Estudo retrospectivo e transversal realizado a partir da revisão de prontuários de pacientes submetidos à cirurgia de pterígio com transplante autólogo de conjuntiva, cola de fibrina e aplicação intraoperatória de mitomicina C. Além disso, foi realizado através de sutura, o selamento da lacuna entre a conjuntiva e cápsula de Tenon. No […]

Objetive: To assess the results of an alternative surgical approach in the excision of primary pterygium by analyzing the rates of recurrence and of intraoperative and postoperative complications. Methods: Retrospective cross-sectional study based reviewing the clinical records of individuals subjected to surgery for pterygium, with conjunctival autograft transplantation, fibrin glue and intraoperative application of mitomycin C. In addition, sealing was performed by suturing the gap between the conjunctiva and Tenon’s capsule. A total of 36 eyes from 35 individuals were […]

Recurrent multifocal conjunctival melanoma originated from preexisting nevus is extremely rare: it occurs in one out of five million individuals. The investigation of this disease is extremely important due to its potential lethality. Thus, this study aims to describe a case of recurrent multifocal conjunctival melanoma originated from preexisting pigmented nevus, which occurred in the city of Patos de Minas, state of Minas Gerais. This is a case study and literature review. Histopathological diagnosis and early staging of the conjunctival […]

OBJECTIVE: This study aims at observing the inhibition of cell proliferation in primary pterygium by the use in vitro of mitomicyn C, cyclophosphamide, methotrexate. METHODS: Pterigyum was removed from seven pacients between 30 and 60 years and were submitted to culture of epithelial cells. Later the effect of drugs was tested on the cells: cyclophsphamide, methotrexate, mitomicyn. The cells were observed for five days under the microscope to assess cellular proliferation, and the experiments were repeated five times RESULTS: When […]

The aim of this article is to demonstrate the probable relationship between the recurrence of toxoplasmic retinochoroiditis and refractive surgery (LASIK). The case consists in a toxoplasmic retinochoroditis recurrence observed in a 33-year-old patient after a LASIK surgery. Fundoscopy revealed a retinochoroiditis focus in activity in the left eye seventeen days after the surgery, adjacent to an old scar of ocular toxoplasmosis. The authors present findings that reinforce possible causal links between LASIK and the recurrence of toxoplasmic retinochoroiditis.
