Efficacy of immunomodulatory therapy with interferon-ß or glatiramer acetate on multiple sclerosis-associated uveitis. / Eficacia del tratamiento inmunomodulador con interferón-ß o acetato de glatirámero en las uveítis asociadas a esclerosis múltiple.

AIM: To analyse the role of interferon-ß or glatiramer acetate in reducing the inflammatory episodes of intra-ocular inflammation in multiple sclerosis-associated uveitis. METHOD: A study was conducted on a non-randomised, retrospective case series of 13 patients with proven multiple sclerosis and uveitis (minimum follow-up, 12 months). All patients were given immunomodulatory treatment (interferon-ß or glatiramer acetate) to control the course of the multiple sclerosis. Patients were compared to themselves before initiating the treatment, in order to assess the difference in uveitis episodes. The main outcome measurements were the number of uveitis episodes with/without immunomodulatory treatment. RESULTS: Uveitis was bilateral in 10 (77%) out of 13 patients. Intermediate uveitis was observed in 11 patients, retinal vasculitis in 3 patients, and one patient was classified as a posterior uveitis. The patients had a mean of 4.15±3.1 episodes of uveitis (range 1-10) during the follow-up period (148.6±84.3 months). When compared to their pre-treatment status, patients on treatment with interferon-ß or glatiramer acetate showed a significant decrease of 0.36 episodes of ocular inflammation per year (P=.02). Mild side effects related to immunomodulatory treatment were observed in 6 (46%) patients, 3 (23%) patients with a flu-like syndrome, and 3 (23%) patients with a skin rash. CONCLUSIONS: Interferon ß or glatiramer acetate could be effective in reducing the uveitis episodes in patients with multiple sclerosis-associated uveitis, and was well tolerated in most patients.

[Intravitreal bevacizumab for choroidal neovascularization associated with Best's disease]. / Bevacizumab intravítreo en neovascularización coroidea asociada a enfermedad de Best.

CASE REPORT: A 27-year old woman presented with loss of vision in the right eye (20/200). Ophthalmoscopic examination showed intrarretinal hemorrhage in the macular region with neurosensory detachment in the right eye, and viteliform deposit on the left eye. Fluorescein angiography and the electrooculogram confirmed the diagnosis of choroidal neovascularization associated with Best's disease. Four weeks after a single bevacizumab intravitreal injection, visual acuity was restored (20/25) and remained stable after a 12 month follow-up. DISCUSSION: Intravitreal bevacizumab appears to be an effective treatment for choroidal neovascularization associated to Best's disease.
