Brief summary

Optical coherence tomography (OCT) of the anterior segment of the eye is a technique that is gaining popularity, which allows you to visualize the anatomy of the anterior segment of the eye, which is formed by gonioscopic tomography in a real-time sample. Target. To study the parameters of the anterior segment of the eye in patients with neovascular glaucoma (NVG) for selection when choosing treatment tactics. Results. During the observation, it was revealed that there is a tendency to thinning of the iris detection and the presence of synechia, expanded manifestations of the trabecular meshwork, which may indicate the features that characterize NVG with closure by 360?. At the initial stages of NVG, a thin layer of capillaries grows on the surface of the iris in the region of the anterior chamber (AAC) and above the trabecular network, then fibrovascular tissue grows, which fuses with the iris and cornea, forming a false AAC. In some cases, endothelial corneas pass through a false angle and form a secondary Descemet's membrane on the anterior surface of the iris. Conclusion. These indicators are used to assess the stage of NVG, since NVG with 360? closure is one of the most refractory types of glaucoma and requires careful analysis to develop further treatment tactics.


Key words

Neovascular glaucoma, optical coherence tomography of the anterior segment of the eye, ophthalmohypertension.
