Changes in Eye Pressure in Glaucoma Patients Treated with Istent Inject W, Monitored by a Contact Lens Sensor

Inclusion Criteria5

• Adult Patients (over 18 years old) with an initial diagnosis of POAG requiring an indication from the patient chart of an untreated IOP of over 21 mm Hg. Diagnosis of NTG requiring an untreated mean diurnal IOP of over 21 mm Hg from diagnosis to enrollment, indicated by the patient chart. Ocular hypertension is defined as a condition in which the IOP was greater than 21 mm Hg in the absence of glaucomatous defects in visual field testing, the normal appearance of the optic disc and nerve fiber layer, anatomic normality, open angles in gonioscopy, and the absence of ocular conditions contributing to the elevation of pressure, such as narrow angles, neovascular conditions, and uveitis.
• Adult Patients (over 18 years old ) diagnosed with POAG and NTG are defined as those with open normal appearing angles, typical glaucomatous optic atrophy (i.e., neural rim thinning, notching, saucerization, or nerve fiber layer disc haemorrhage), and typical glaucomatous visual field damage (i.e., arcuate, paracentral scotoma, or nasal step).
• Adult Patients (age over 18 years old ):
• with unilateral or bilateral open-angle glaucoma (POAG) without previous eye surgery, treated with topical anti-glaucoma medications, who need glaucoma surgery with iStent inject W. The investigators will include patients with isolate iStent surgery and patients with combined cataract and iStent surgery. In cases of bilateral glaucoma, the two eyes of the same patient may be included consecutively.
• For the control group only: Patients with topical hypotensive glaucoma treatment requiring cataract surgery.
