Cutting-edge issues in sympathetic ophthalmia approach and six case reports: a T cell-mediated autoimmune response.

Sympathetic ophthalmia is a rare and potentially devastating bilateral diffuse granulomatous panuveitis. It is caused by surgical or non-surgical eye injuries and is an uncommon and serious complication of trauma. It is diagnosed clinically and supported by imaging examinations such as ocular ultrasonography and optical coherence tomography. Its treatment consists of immunosuppressive therapy with steroids and sometimes steroid-sparing drugs, such as cyclosporine, azathioprine, cyclophosphamide, and mycophenolate mofetil. Fast and effective management with systemic immunosuppressive agents allows for disease control and achievement of good visual acuity in the sympathizing eye. By contrast, enucleation should be considered only in situations where the injured eye has no light perception or in the presence of severe trauma. In addition to a bibliographic review of this topic, we report six cases involving different immunosuppressive and surgical treatment modalities.

Optical coherence tomography findings in fungal uveitis.

PURPOSE: The purpose of the study was to describe the vitreal, retinal, and choroidal features of eyes affected by endogenous endophthalmitis (EE) and evaluate the effects of systemic antifungal drug treatment and pars plana vitrectomy by using spectral domain optical coherence tomography (SD-OCT). METHODS: Medical records and SD-OCT images of eyes diagnosed with EE at a single uveitis tertiary referral center in Brazil were acquired at the time of diagnosis, after 7 days of high-dose antifungal drug treatment, and at follow-up assessments performed 30 days after resolution. RESULTS: Thirteen eyes were enrolled in the study. All patients showed hyperreflective round-shaped lesions on SD-OCT and pre-retinal aggregates. Five eyes responded to antifungal systemic oral drugs despite showing vitreous opacity. The response to treatment was observable on optical coherence tomography (OCT) images. CONCLUSION: Fungal endophthalmitis showed typical features on SD-OCT, facilitating early diagnosis and treatment despite the absence of vitreous culture or biopsy. This study suggests that OCT images can be used to support diagnosis by physicians who do not have access to vitreoretinal surgery.
