Methods: In this prospective case series, patients with persistent, non-resolving, or progressive SCD after glaucoma surgery were enrolled. For those with non-resolving or progressive SCD despite of using systemic corticosteroids, topical atropine and topical steroids, one milliliter of TA (40mg/mL) was injected inferotemporally into the posterior subtenon space.
Background: To investigate the long-term effect of hypertensive phase (HP) on the clinical outcomes of Ahmed glaucoma valve (AGV) implantation.
Method: The records of patients with different etiologies of glaucoma who underwent AGV implantation with at least 3 years of follow-up were retrospectively reviewed. HP was defined as the IOP > 21 mm Hg during the first three months after surgery.
Purpose: To report a case of ciliary body melanoma with acute high intraocular pressure (IOP) due to pigment dispersion, treated by limited trans-scleral cyclophotocoagulation (TSCPC) and plaque radiotherapy.
Methods: A 33-year-old woman was referred to clinic with acute ocular pain and decreased visual acuity from 1 week before presentation. The IOP was 55 mmHg accompanied by red eye, perilimbal injection, mild corneal edema (stromal and epithelial), scattered pigment dust on central corneal endothelium, 4 anterior chamber pigments, and pigmented cells.
Purpose: To investigate the frequency of persistent postoperative ptosis (PP) following trabeculectomy or Ahmed glaucoma valve (AGV) implantation and to analyze the associated factors.
Methods: It is a prospective observational study on glaucoma patients who underwent trabeculectomy or AGV implantation from October 2015 to June 2017 in a tertiary center. Margin reflex distance 1 and 2 (MRD1 and 2) and levator function were measured before and at least 6 months, postoperatively.
Purpose: To investigate the effect of trabeculectomy on peripapillary and macular vessel density (VD) using optical coherence tomography angiography (OCT-A) in patients with primary open-angle glaucoma.
Methods: This is a prospective, interventional study on 32 glaucoma eyes (21 patients) who underwent trabeculectomy. Optic nerve head (ONH) and macular structural and OCT-A scans were performed before surgery and at one and six months postoperatively with the Avanti device (AngioVue System, Optovue Inc.
Background/aims: To evaluate the success of Mitomycin C (MMC) augmented trabeculectomy with or without intravitreal bevacizumab in patients with diabetes without neovascular glaucoma.
Methods: Fifty-six patients with diabetes who needed trabeculectomy were randomised to either combination of 2.5 mg intravitreal bevacizumab and subconjunctival MMC (group A, 28 eyes) or subconjunctival MMC alone (group B, 28 eyes).

Purpose: To compare the long-term outcomes obtained by residents and attending surgeons performing trabeculectomy.
Methods: After reviewing medical records of the patients, 41 residents performing trabeculectomy under supervision of attendings were compared to 41 attendings performing trabeculectomy. The primary outcome measure was the surgical success defined in terms of intraocular pressure (IOP) ≤ 21 mmHg (criterion A) and IOP ≤ 16 mmHg (criterion B), with at least 20% reduction in IOP, either with no medication (complete success) or with no more than 2 medications (qualified success).
Purpose: To determine whether photorefractive keratectomy (PRK) has a significant effect on optic nerve head (ONH) parameters and peripapillary retinal nerve fiber layer (RNFL) thickness measured by the Heidelberg Retina Tomograph 3 (Heidelberg Engineering GmbH, Heidelberg, Germany) in eyes with low to moderate myopia.
Methods: This prospective, interventional case series, includes 43 consecutive myopic eyes which were assessed on the day of PRK and 3 months postoperatively using the HRT3. Among the stereometric parameters, we compared disc area, linear cup disc ratio, cup shape measure, global rim area, global rim volume, RNFL height variation contour and mean RNFL thickness; out of the Glaucoma Probability Score (GPS) we assessed changes in global value, rim steepness temporal/superior, and temporal/inferior, as well as cup size and cup depth before and after PRK.
