Aim: To investigate vascular changes in different stages of glaucoma and to evaluate the role of optical coherence tomography angiography (OCTA) in the early diagnosis of glaucoma.
Methods: Glaucoma patients and healthy controls (=29 eyes) were investigated in this cross-sectional comparative study. Glaucoma patients were grouped as ocular hypertension (=44 eyes), preperimetric glaucoma (PPG; =32 eyes), early glaucoma (EG; =35 eyes), moderate stage glaucoma (MG; =36 eyes), and advanced glaucoma (AG; =35 eyes).
Objectives: Our purpose was to investigate vascular alterations in the non-glaucomatous eyes of patients with unilateral primary open angle glaucoma using optical coherence tomography angiography and to evaluate the role of vascular damage in glaucoma pathogenesis.
Materials And Methods: This cross-sectional study included 60 eyes of 30 patients with unilateral glaucoma (63.4±8.
Incisional surgeries such as trabeculectomy reduce the resistance of the eye to trauma. Trabeculectomy is often performed together with mitomycin C, and late onset hypotony is already an expected complication in these eyes. This case report presents a patient who developed dehiscence of the scleral flap and hypotony maculopathy after Valsalva maneuver after 5.

Purpose: To assess the risk factors associated with the development of hypotony after Ahmed glaucoma valve (AGV) implantation.
Methods: One hundred and ninety-three eyes of 177 patients with various types of glaucoma that were treated with AGV implantation were retrospectively evaluated. Intraocular pressure lower than 6 mmHg related to the surgery is defined as postoperative hypotony.
Purpose: The purpose of this study is to evaluate the factors affecting the success of needling surgery for early filtering bleb failure after trabeculectomy.
Methods: Patients who underwent a single needling surgery within 3 months after trabeculectomy were retrospectively evaluated. Glaucoma type, intraocular pressure (IOP), and medical treatments before trabeculectomy; the presence of hypotony after trabeculectomy; bleb type; IOP before needling; lens status; complications; IOP after 1, 6, and 12 months; and medical treatments after needling were recorded.
Purpose: To evaluate the prevalence of uveitic glaucoma (UG) in the Turkish population and investigate the primary underlying diseases.
Methods: This multicenter, cross-sectional, prospective study included patients who presented to the glaucoma units of 10 tertiary ophthalmology departments in Ankara, Turkey from 15th March to 16th May 2015 and fulfilled the criteria of UG. Patients were inspected for age, sex, medical history, best corrected visual acuity, biomicroscopic findings, intraocular pressure values, and visual field results.
Purpose: To evaluate alterations in corneal biomechanical properties before and 6 months after conventional trabeculectomy (TRAB) and Ahmed glaucoma valve (AGV) implantation.
Methods: Thirty-nine eyes of 39 patients were evaluated retrospectively. Complete ophthalmological examinations including evaluation of corneal biomechanical properties using the Ocular Response Analyzer were performed before and after 6 months postoperatively.
Objectives: To report the results obtained from glaucoma drainage device (GDD) implantation in patients with aniridia-related glaucoma and to review the literature.
Materials And Methods: We retrospectively reviewed 6 patients who underwent GDD implantation for glaucoma secondary to congenital aniridia between April 2001 and February 2015. Data on age at surgery, gender, laterality, surgeries before GDD implantation, GDD model, concomitant ocular disorders, visual acuity, and intraocular pressure (IOP) values before and at 1 and 12 months after GDD implantation, medications, follow-up period, findings during last visit, complications, and course of disease were collected.
Purpose: To evaluate antioxidant effects of active vitamin D (calcitriol) against high-dose radioiodine (RAI) therapy-associated damage of lacrimal gland.
Materials And Methods: Wistar albino rats were used and divided into three groups randomly (n = 12/group). The first group was appointed as the negative control group and received no RAI or medication.
Purpose: To assess and compare the outcomes of trabeculectomy with and without antimetabolites (AMs) and glaucoma drainage devices (GDDs) in the management of elevated intraocular pressure (IOP) after penetrating keratoplasty (PK).
Methods: Data of 84 eyes of 81 patients who underwent trabeculectomy (12 eyes without an AM and 42 eyes with an AM) or GDD implantation (30 eyes) after PK were reviewed retrospectively. The main outcome measures were IOP control, corneal graft survival, and postoperative ocular complications.
