Retinal Imaging and Optical Coherence Tomography of Choroidal Haemangioma Mimicking Central Serous Chorioretinopathy.

Intraocular tumours, such as choroidal haemangioma, can cause exudative retinal detachments, which mimic central serous chorioretinopathy. Key symptoms of a choroidal haemangioma include reduced visual acuity, visual field defects, and metamorphopsia. More rarely, it can cause photopsia, myodesopsia, and pain.

Multicolor Scanning Laser Imaging in Diabetic Retinopathy.

Significance: Diabetic retinopathy is a common cause of blindness in individuals younger than 60 years. Screening for retinopathy is undertaken using conventional color fundus photography and relies on the identification of hemorrhages, vascular abnormalities, exudates, and cotton-wool spots. These can sometimes be difficult to identify.

To stop or not? Tamoxifen therapy for secondary prevention of breast cancer in a patient with ocular toxicity.

We report a case of a patient with treated breast cancer whose dilated fundus examination showed crystalline deposits in the central region of the macula. She was taking tamoxifen for secondary prevention. Optical coherence tomography revealed individual refractile deposits associated with intraretinal cysts in both eyes.

Angiographic evidence of peripheral ischemia in diabetic retinopathy and the risk of impending neovascularisation.

The appearance of biomicroscopic evidence of neovascularisation is the main indication for scatter laser treatment in patients with known diabetic eye disease. We describe a patient with an unusually aggressive variant of proliferative disease and a distinct angiographic signature. In an interventional case report with angiographic findings, we found that angiographic evidence of extensive capillary dropout in patients with known diabetic retinopathy should translate into a low threshold for panretinal photocoagulation treatment based on a high risk for progression to sight-threatening proliferative disease.

Presumed non-accidental injury with retinal haemorrhages--findings from a tertiary referral centre in the United Kingdom.

Aim: To describe the clinical and demographic features of patients with retinal haemorrhages from presumed non-accidental injury (NAI) at a tertiary referral centre in Leeds over a 2-year period.

Methods: All patients with retinal haemorrhages from presumed NAI between 1 January 2007 and 31 December 2008 were retrospectively identified from the hospital RetCam® (Clarity Medical System, Pleasanton, CA, USA) database. Case-notes, fundus photographs and radiological studies were retrieved for all patients and examined.

Monovision: a refractive consideration in cataract surgery after vitrectomy?

Cataract is the most common complication of vitrectomising surgery in the phakic eye. Progressive nuclear sclerosis (NS) causes a myopic shift. This change in refractive status can predispose to the development of monovision in presbyopic individuals.

Multiple parallel-line endotheliitis--a form of herpes simplex keratitis?

Purpose: To report a case of multiple parallel-line endotheliitis with a possible link to herpes simplex virus.

Case Report: An 89-year-old woman presented with new onset reduced vision in her left eye. Her visual acuity with pinhole was 20/120 with the affected eye and 20/30 in the right.

First-year experience of chemotherapy for advanced retinoblastoma in Tanzania: disease profile, outcomes, and challenges in 2008.

Purpose: To examine the profile of retinoblastoma in a national tertiary referral center in Tanzania and to report first-year outcomes of its treatment using chemotherapy.

Methods: All patients with retinoblastoma referred in 2008 were included. Disease was classified on clinical grounds as ocular, orbital, or metastatic.

Diaton tonometry: an assessment of validity and preference against Goldmann tonometry.

Background: To assess agreement between the Diaton, a new transpalpebral tonometer, and Goldmann applanation tonometry, the accepted gold standard.

Design: Comparative study of two devices in a hospital setting.

Participants: Two hundred and fifty-one patients attending the eye casualty and general ophthalmology clinics at St James' University Hospital, Leeds between February and December 2009.

Drusen and the misleading optic disc.

Optic disc drusen are acellular calcified deposits occurring in small optic discs. They have a prevalence of up to approximately 2% and are bilateral in 75% of cases. Their size and fundosc pic visibility increase with age, and they are commonly responsible for the misdiagnosis of papilloedema by the unwary.

Goldmann tonometry versus the Tono-Pen XL for intraocular pressure measurement: an evaluation of the potential impact on clinical decision making in glaucoma.

Aim: To assess the validity of the Tono-Pen XL as an alternative to the Goldmann applanation tonometer (GAT) for the measurement of intraocular pressure (IOP) in patients with ocular hypertension (OHT) and glaucoma.

Methods: Over a 3 month period, patients with OHT or glaucoma attending a general clinic had IOP measurements taken using the Tono-Pen XL and the GAT. Tono-Pen measurements were taken by suitably trained nursing staff, while Goldmann tonometry was performed by the examining ophthalmologist.

The efficacy of 5% povidone-iodine for 3 minutes prior to cataract surgery.

Purpose: To evaluate the efficacy of 3 minutes of 5% povidone-iodine for skin and conjunctival antisepsis prior to cataract surgery as recommended by the European Society of Cataract and Refractive Surgeons.

Methods: A prospective controlled study of 54 patients undergoing unilateral cataract surgery by phacoemulsification was undertaken. The eye undergoing surgery was prepared with 5% povidone-iodine for 3 minutes.

Anatomical correlate of a persistent paracentral scotoma after an airbag injury.

Ocular injuries caused by deploying airbags are well-described in the literature and can be either mechanical or chemical in nature. To the authors' knowledge, this is the first report describing an isolated paracentral scotoma noted immediately after an airbag injury. The use of optical coherence tomography revealed an anatomical correlate of the scotoma.

A simplified technique for incision and curettage of chalazia.

The surgical treatment of chalazia is one of the most common minor operations performed in ophthalmology. The conventional approach involves injection of local anesthetic, clamping, incision of the palpebral conjunctiva with a scalpel blade, and curettage of the contents. We describe a simplified approach, which in addition to reducing costs, may also minimize scarring of the palpebral conjunctiva.
