PURPOSE To describe the incidence, features, management, and risk factors of post-intravitreal anti-VEGF endophthalmitis (PIAE) in patients undergoing treatment for exudative age-related macular degeneration in the United Kingdom. METHODS Prospective observational case control study. Forty-seven cases of PIAE were identified through the British(More)
Fuchs heterochromic uveitis (FHU) in its classic presentation is a unilateral, chronic, low grade, often asymptomatic anterior uveitis. It is characterized by a classic triad of iris heterochromia, cataract and keratic precipitates. Neovascularization of the iris and the anterior chamber (AC) angle (radial and circumferential) occurs in 6-22% of cases. This(More)
PURPOSE To characterize corneal, internal, and total ocular monochromatic higher-order aberration (MHOA) changes that occur in the aging eye. METHODS Prospective observational case series including 300 eyes of 167 patients (mean age = 63.8 years) attending the ophthalmology service at University Hospital Ayr, Scotland. Corneal, internal, and total ocular(More)
OBJECTIVE To determine the prevalence of corneal astigmatism, changes in astigmatism, and biometry measurements with age and to correlate fellow eye measurements of patients undergoing cataract surgery. DESIGN Prospective, observational study. PARTICIPANTS 3498 eyes of 1814 patients undergoing cataract surgery. METHODS Setting was a single center(More)
A 7-year-old Caucasian girl presented with a pigmented lesion on the left bulbar conjunctiva that increased in size from 1 mm to 4 mm over a 12-month period. She underwent excision biopsy and reconstruction of the ocular surface with amniotic membrane graft. Histopathology showed the naevus was composed of somewhat swollen naevus cells with clear cytoplasm(More)
AIMS To report long term visual outcomes, complications and graft survival of patients undergoing deep anterior lamellar keratoplasty (DALK) to treat corneal scarring secondary to herpes simplex virus (HSV) keratitis. METHODS Retrospective, non-comparative case series. 18 patients who underwent DALK for HSV keratitis related corneal scarring between(More)
Conjunctival lymphangiectasia is an uncommon clinical condition in which there is dilatation of lymphatic channels in the bulbar conjunctiva. Conjunctival lymphangiectasia is a rarely appreciated ocular surface disorder that typically occurs as a secondary phenomenon in response to local lymphatic scarring or distal obstruction. Conjunctival(More)
BACKGROUND The risks of orbital biopsy depend on the lesion's location and relationship with surrounding structures. Complications include reduced vision, although visual outcomes following orbital biopsy are not widely reported. AIMS To determine visual outcomes following orbital biopsy in Gartnavel General Hospital's Oculoplastic and Oncology Service.(More)
INTRODUCTION Endogenous endophthalmitis is a sight-threatening condition caused by microorganisms crossing the blood-ocular barrier and inducing profound intraocular inflammation.
