To emphasize and evaluate the benefits and usefullness of ophthalmic microendoscope ( OME ) as a diagnostic and surgical tool in eyes with uveitis.
Retrospective case series
Ten eyes of the 10 patients with a various etiologies of üveitis were studied. The reasons of uveitis were ankylosing spondylitis, Behçet’s Disease, Idiopathic, toxocariasis, sarcoidosis, acute traumatic endophthalmitis ( 2 eyes ), propionibacterium acnes chronic endophthalmitis ( 3 eyes ). They had various anterior segment and / or vitreoretinal pathologies secondary to uveitis. When standard operating microscopic viewing was limited or impossible due to visual axis obstruction (corneal opacity, cataract, small / fixed pupilla or pupillary membrane ) or we needed to evaluate the retroiridal space, to find the retinal breaks and to assess the condition of the fundus, fused – fiber type endoscopic system was used for both diagnostic and surgical purposes during the vitreoretinal surgery.
The reasons for endoscopic assistance during the vitreoretinal surgery were the need for retroiridal imaging ( 10 eyes ), endolaser application on peripheral retina (1 eye), visually obstructive light reflections occuring during air / fluid exchange ( 4 eyes ), corneal haze ( 8 eyes), small or fixed pupil ( 8 eyes), to detect the cyclitic membrane as a cause of hypotony ( 8 eyes), retinal incarceration ( 3 eyes) and retinal breaks( 2 eyes ). OME allowed a clear view and to continue the vitreoretinal surgery when anterior segment conditions precluded a posterior view. It also allows the surgeon to visualize the vitreous base changes and retroiridal space to detect the missed or hidden peripheral retinal tears, and easy endoscopic endolaser application around the peripheral retinal breaks. OME was also useful to detect the tissue or retina incarceration into the sclerotomy sites, and confirming correct pars plana infusion cannula placement when not visible microscopically. It was possible to do a rapid assessment of the condition of the macula, retina, and optic nerve, and the feasibility of a secondary procedure ( 4 eyes).
OME permitted observation of microscopically inaccessible areas as a diagnostic tool. It is also very useful complementary method for safely complete vitrectomy when operating microscope become insufficient.
