Correlation between optical coherence tomography results and the Scoring Tool for Assessing Risk (STAR) score in patients with ocular hypertension.

Purpose: To correlate retinal nerve fiber layer thickness (RNFL) and optic nerve head (ONH) parameters measured with optical coherence tomography (OCT) with the Scoring Tool for Assessing Risk (STAR) threshold in patients with ocular hypertension (OH).

Methods: The study included 92 patients with OH. They were divided into low-risk (n=32), moderate-risk (n=36), and high-risk (n=24) groups according to STAR criteria.

Quantitative assessment of anterior chamber parameters in pigmentary glaucoma using slit-lamp optical coherence tomography.

Purpose: To quantitatively assess the parameters of anterior chamber and angle dimensions by slit-lamp optical coherence tomography (SL-OCT) in eyes with pigmentary glaucoma (PG).

Methods: A total of 18 eyes of 11 patients with PG and 18 eyes of 11 healthy volunteers were included in the study. Anterior chamber depth (ACD), anterior chamber volume (ACV), spur distance (internal horizontal anterior chamber diameter), central corneal thickness (CCT), angle opening distance at 500 microm from the scleral spur (AOD 500), and trabecular iris space area at 500 microm from the scleral spur (TISA 500) parameters were detected by SL-OCT.

Incidence and prognosis of ocular hypertension secondary to viral uveitis.

This retrospective study was designed to estimate the cumulative incidence of glaucoma in viral uveitis. Seventy-six consecutive patients with viral stromal keratouveitis were divided into two groups according to the etiologic agents herpes simplex virus (HSV) keratouveitis (n = 58) and herpes zoster virus (HZV) keratouveitis (n = 18). The groups were evaluated for the incidence and prognosis of ocular hypertension.

A comparative study between diode laser cyclophotocoagulation and the Ahmed glaucoma valve implant in neovascular glaucoma: a long-term follow-up.

Background: To compare the efficacy, safety, and long-term results of intraocular pressure (IOP) reduction by diode laser contact cyclophotocoagulation (DCPC) and Ahmed glaucoma valve (AGV) implant in cases of neovascular glaucoma.

Methods: A total of 66 eyes of 66 patients with neovascular glaucoma were prospectively assigned to either DCPC or AGV implantation. All patients underwent a baseline complete ophthalmologic examination and IOP measurement by Goldmann applanation tonometry before and after 1,3, 6, 12, and 24 months follow-up.

The correlation between visual field defects and focal nerve fiber layer thickness measured with optical coherence tomography in the evaluation of glaucoma.

Purpose: To study the correlation between known visual field defects and retinal nerve fiber layer (RNFL) thickness detected by optical coherence tomography (OCT) in glaucomatous eyes.

Materials And Methods: Visual field parameters and OCT RNFL measurements of 28 eyes of 28 glaucoma patients with various stages of glaucoma were compared with 38 eyes of 38 normal age-matched controls. A perimetric nerve fiber bundle map was built by dividing the visual field area into 21 zones.

Incidence and risk factors in secondary glaucomas after blunt and penetrating ocular trauma.

Purpose: This retrospective study was designed to evaluate the risk factors for the development of posttraumatic glaucoma after ocular trauma.

Methods: Data were obtained from the records of 102 patients (105 eyes) that experienced blunt or penetrating ocular trauma and presented to our center between January 1987 and April 2006. Logistic regression was used to evaluate the association between the baseline structural and functional ocular characteristics and posttraumatic glaucoma.

Trabeculectomy with mitomycin-C in uveitic glaucoma associated with Behçet disease.

Purpose: To determine the effect of intraoperative application of Mitomycin-C (MMC) with trabeculectomy in uveitic glaucoma associated with Behçet disease.

Materials And Methods: Twenty-six eyes of 26 patients with uveitic glaucoma associated with Behçet disease who underwent trabeculectomy with MMC between 1996 and 2001 were reviewed in this retrospective, noncomparative study. Trabeculectomy + MMC in concentration of 0.

Primary viscocanalostomy versus trabeculectomy for primary open-angle glaucoma: three-year prospective randomized clinical trial.

Purpose: To compare the efficacy and safety of viscocanalostomy and trabeculectomy in patients with primary open-angle glaucoma (POAG).

Setting: Department of Ophthalmology, Ankara Education and Research Hospital, Ankara, Turkey.

Methods: In this prospective randomized trial, 50 eyes of 50 patients with medically uncontrolled POAG were randomized to have a trabeculectomy (25 eyes) or a viscocanalostomy (25 eyes).

Decompression retinopathy after Ahmed glaucoma valve implantation in a patient with congenital aniridia and pseudophakia.

We present the case of a 16-year-old adolescent boy with congenital aniridia and pseudophakia who developed decompression retinopathy in a glaucomatous eye after Ahmed glaucoma valve implantation combined with anterior vitrectomy. On the first postoperative day, dot and blot-shaped hemorrhages scattered in the posterior pole were observed. The hemorrhages resolved over 6 months, and the visual acuity returned to the preoperative level.

Hemorrhagic Descemet's membrane detachment after viscocanalostomy.

We report a case of hemorrhagic detachment of Descemet's membrane after viscocanalostomy. A 60-year-old man with pseudoexfoliative glaucoma had an uneventful viscocanalostomy in the right eye. On the first postoperative day, a 5.

Penetration of topically applied ciprofloxacin and ofloxacin into the aqueous humor and vitreous.

Purpose: To determine the intraocular penetration of topical drops of 2 antibiotics, ciprofloxacin 0.3% and ofloxacin 0.3%, into the aqueous humor and vitreous and to relate these levels to the miminum inhibitory concentration (MIC(90)) for organisms associated with ocular bacterial infections.

Determination of betaxolol in human aqueous humour by high-performance liquid chromatography with fluorescence detection.

A reversed-phase high-performance liquid chromatographic method is described for the determination of betaxolol in human aqueous humour. Betaxolol and the internal standard metoprolol were extracted with cyclohexane and separated on a reversed-phase column (Luna C(18), 250 x 4.6 mm, 5 microm) with a mobile phase containing acetonitrile-phosphate buffer (40:60, v/v) at a flow-rate of 0.
