Threshold versus intensity functions in two-colour automated perimetry.

Purpose: Two-colour computerised perimetry is a technique developed for assessing cone- and rod-function at fixed background luminances in retinal disease. However, the state of adaptation during testing is unknown but crucial in the interpretation of results. We therefore aimed to determine the adaptational state of rod- and cone-mechanisms in two-colour perimetry.

Retinal detachments in southern New Zealand: do poorer patients have poorer outcomes?

Aims: To investigate associations between socioeconomic status, retinal detachment type and post-operative visual outcomes in southern New Zealand. 

Methods: A retrospective review of all cases of rhegmatogenous retinal detachments in Dunedin Hospital over two years was performed. Patient demographics and macula involvement at presentation were the primary outcome measures.

Progression of diabetic maculopathy in patients on the Wellington Diabetic Screening Programme initially graded M3.

Aim: To determine the likelihood of progression from M3 grade maculopathy, and therefore the safety of these patients remaining under the care of a primary screener.

Methods: Patients graded M3 at diabetic screening were selected from the Wellington screening database. Photographs for this visit and the subsequent visit were obtained, and graded by a consultant ophthalmologist.

Repeatability of primary selective laser trabeculoplasty in patients with primary open-angle glaucoma.

To determine if primary selective laser trabeculoplasty (SLT) can be repeated with clinical benefit in patients with primary open-angle glaucoma (POAG). Forty-two eyes of 42 patients with POAG were studied. All patients underwent primary SLT treatment of 40-50 shots to the trabecular meshwork over 360°.

The 'Dr Google' phenomenon--missed appendicitis.

Self-diagnosis has been around for many years. In today's society with free access to information, particularly through the Internet, it is more prominent than ever. With new information sources available to patients, doctors may have their diagnostic process influenced.
