Location of Initial Visual Field Defects in Glaucoma and Their Modes of Deterioration.

Purpose: To describe the location of initial visual field defects (VFD) in glaucoma, their modes of deterioration, and those factors associated with different modes of deterioration.

Methods: Patients with POAG were categorized into four groups based on three consecutive initial VFD: (1) superior paracentral defects (PD), (2) inferior PD, (3) superior nasal defects (ND), and (4) inferior ND. According to the worsening of the VF, four further subgroups were identified: (1) superior central worsening (CW), (2) inferior CW, (3) superior peripheral or nasal worsening (NW), and (4) inferior NW.

Trabeculectomy Can Improve Long-Term Visual Function in Glaucoma.

Purpose: To measure the magnitude and direction of visual field (VF) rates of change in glaucoma patients after intraocular pressure (IOP) reduction with trabeculectomy.

Design: Retrospective, comparative, longitudinal cohort study.

Participants: Patients with open-angle glaucoma.

Nylon Hang Back Sutures in the Repair of Secondary Ptosis Following Overcorrected Dysthyroid Upper Eyelid Retraction.

Purpose: Repair of blepharoptosis secondary to surgical overcorrection of thyroid related primary upper eyelid retraction (secondary ptosis) can be unpredictable. This study describes the long-term results of "hang-back" nylon sutures, for an anterior approach surgical repair of secondary ptosis.

Methods: This was a retrospective consecutive case note review of patients referred with secondary ptosis (after prior upper eyelid lowering for thyroid eye disease), under the care of a single surgeon at Moorfields Eye Hospital & subsequently at Barking Havering Redbridge University Hospitals NHS Trust (SSD).

Technique of combined glaucoma tube shunt and keratoprosthesis implantation.

Objective: To describe the surgical technique and outcomes of implantation of a glaucoma drainage device (GDD) at the time of Boston type I keratoprosthesis (KPro) procedure.

Methods: Consecutive cases of combined GDD and KPro surgery performed between January 2005 and January 2011 with at least 6 months of follow-up were reviewed. Outcome measures included visual acuity, number of glaucoma medications, and complications.

Disc haemorrhage is associated with the fast component, but not the slow component, of visual field decay rate in glaucoma.

Background/aims: To investigate the association of disc haemorrhage (DH) with regional visual field (VF) decay in glaucoma.

Methods: Retrospective longitudinal study was performed. Patients from the University of California, Los Angeles, glaucoma database were assigned to two groups based on the presence or absence of a DH.

Measurement of the optic disc vertical tilt angle with spectral-domain optical coherence tomography and influencing factors.

Purpose: To report a novel method for measuring the vertical tilt angle of the optic nerve (ON) head and to investigate the associated factors.

Design: Cross-sectional diagnostic study.

Methods: One hundred and twelve normal, glaucomatous, and glaucoma suspect eyes (99 patients) were enrolled in this study.

Validation of point-wise exponential regression to measure the decay rates of glaucomatous visual fields.

Purpose: This study was conducted to validate a recently described technique for measuring the rates of visual field (VF) decay in glaucoma.

Methods: A pointwise exponential regression (PER) model was used to calculate average rates of faster and slower deteriorating VF components, and that of the entire VF. Rapid progressors had a faster component rate of >25%/year.

Arthroscopic excision of a painful bipartite patella fragment.

Bipartite patella, although usually asymptomatic, can become a source of persistent pain following injury. When nonoperative treatments such as physiotherapy and rest fail to produce any resolution in the symptoms, surgery is usually performed. This may include excision of the painful fragment, lateral retinacular release, or detachment of the vastus lateralis insertion, generally performed as open surgical procedures.
