“…It is also very important to evaluate closed-angle glaucoma secondary to anterior rotation of the ciliary body. Anterior-segment OCT also may be helpful to evaluate the length and position of glaucoma drainage device tubes and their relationship with the corneal endothelium [ 9 ] as well as to evaluate filtering bleb in eyes that have undergone filtration surgery [ 10 , 11 ].…”

Uveitic glaucoma (UG) typically is associated with very high intraocular pressure (IOP) and more intense optic nerve damage than other glaucoma types. This secondary glaucoma requires an early diagnosis and adequate management of both uveitis and glaucoma. It is mandatory to identify the mechanisms of IOP elevation that in many eyes have multiple combined mechanisms. Management of these patients commonly requires an interdisciplinary approach that includes a glaucoma specialist and rheumatologist to control the inflammation and IOP. Glaucoma surgery is required early in these patients due to the high IOP usually present and is less successful than in primary open-angle glaucoma. Recurrent uveitic episodes, multiple mechanism, and the complications associated with uveitis make surgical management of UG challenging. In this review, the management and treatment of UG are updated to clarify the pathogenesis and prevent optic nerve damage.

“…В результате работы было установлено, что трубка клапана в отдаленном послеоперационном периоде мигрирует, особенно в глазах с вторичной глаукомой, после сквозной кератопластики и хроническим увеите. Авторы на основании полученных результатов рекомендуют имплантировать клапан Ahmed с достаточным запасом длины трубки в таких глазах для предупреждения смещения трубки в слои склеры и обтурации его просвета [29,30].…”

Optical coherence tomography (OCT) is a noncontact method that provides two-dimensional (three-dimensional for some models) highresolution images of the anterior eye segment, with an axial resolution in the range from 3 to 20 µm. Two OCT diagnostics platforms are available: time-domain and spectral OCT. OCT provides a qualitative and quantitative assessment of the most important structures involved in the glaucoma pathogenesis: the state of the optic nerve head, the thickness of the nerve fiber layer, the anterior chamber angle and the trabecular apparatus. The OCT advantage is the ability to visualize surgically formed outflow tracts in the early postoperative period after antiglaucoma surgery. The OCT studies of the antiglaucomatous surgery zone are presented in detail in the literature, namely, the assessment of such biometric parameters of filtering bleb (FB) as wall thickness and reflectivity, radial length and height. According to the literature, the presence of a multi-layer filtration cushion 6 months after the operation indicates a favorable prognosis for the duration of the hypotensive effect of the operation. Such signs as low reflectivity of the filtration cushion wall and the presence of episcleral fluid are in most cases associated with a successful outcome of trabeculectomy. OCT studies of a filtration cushion after trabeculectomy make it much easier to choose an area for revision and nidling. In addition, OCT is used to assess anatomical features in the field of surgical intervention with drains and drainage devices. Currently OCT is widely implemented at the prehospital stage, however, engineers did not stop at the achieved level and carried out the integration of spectral OCT with an operating microscope. The possibilities of intraoperative imaging with cataract phacoemulsification (FEC) and trabeculectomy, implantation of the Ahmed valve, reconstruction of the anterior chamber angle, revision of the filtration bag and nidlinge are described in the literature. Conclusion. OCT is a very valuable method of intravital imaging of the antiglaucoma operation zone. It allows assessing the level of retention of intraocular fluid, determining the functional activity, the location of drains and drainage devices both in the early and late postoperative period.

“…If anterior bowing of the iris is prominent, short tube may be prone to be occluded by the iris. In addition, it has been reported that tube retraction can develop after glaucoma drainage implant surgery (Sarkisian 2009; Lopilly Park et al. 2012).…”

“…Patients with tube obstructions caused by membrane or pars plana insertion of the tube or who developed postoperative complications that required additional surgical intervention were excluded from the present study. All surgeries were performed using Model FP7 AGVs (New World Medical Inc., Rancho Cucamonga, CA, USA) as described previously (Lopilly Park et al. 2012).…”
