papillitis without vitritis. A case report in an immunocompetent Congolese patient.

Introduction: Unilateral papillitis and neuroretinitis are uncommon manifestations of ocular infection and pose particularly challenging diagnosis problems. Due to the limited accessibility of healthcare and poor socioeconomic status of a significant proportion of the population in Democratic Republic of the Congo, knowledge of seroprevalence rates for toxoplasmosis remains key to the health system. When papillitis or neuroretinitis is suspected, vitreous inflammatory reaction is usually present at various degrees on the initial examination as a diagnosis clue.

Comparison of the corneal biomechanical properties with the Ocular Response Analyzer® (ORA) in African and Caucasian normal subjects and patients with glaucoma.

Purpose: To compare corneal hysteresis (CH) and corneal resistance factor (CRF) measured with the Ocular Response Analyzer(®) tonometer (ORA) between (i) African normals and treated primary open-angle glaucoma (POAG) patients and (ii) between normals and treated POAG Caucasians. To analyse the correlation of CH and CRF with visual field (VF) defects in the two groups.

Methods: This comparative study included 59 African (29 (POAG), 30 normals) and 55 Caucasians (30 POAG and 25 normals) subjects.

Evaluation of corneal biomechanical properties with the Reichert Ocular Response Analyzer.

Purpose: To compare corneal hysteresis (CH) and corneal resistance factor (CRF) measured with the Ocular Response Analyzer (ORA) in patients with primary open-angle glaucoma (POAG), patients with ocular hypertension (OHT), and normal subjects (NL); and to assess correlations of CH and CRF with corneal-compensated intraocular pressure (IOPcc), Goldmann applanation tonometry (GAT), glaucoma type, central corneal thickness (CCT), previous filtering procedure, and antiglaucoma medications.

Methods: A total of 108 POAG, 22 OHT, and 24 NL were enrolled in this observational study. Goldmann applanation tonometry and ORA were performed in a randomized sequence followed by pachymetry.

Physiological diurnal variability and characteristics of the ocular pulse amplitude (OPA) with the dynamic contour tonometer (DCT-Pascal).

Purpose: The Pascal dynamic contour tonometer (DCT) allows measurement of intraocular pressure (IOP) independently of corneal properties. It records, simultaneously, haemodynamic IOP fluctuations and the difference between the systolic and the diastolic IOP corresponding to the ocular pulse amplitude (OPA). The OPA indirectly reflects choroidal perfusion and could be considered as an independent risk factor in glaucoma.

Anterior segment imaging using optical coherence tomography and ultrasound biomicroscopy in secondary pigmentary glaucoma associated with in-the-bag intraocular lens.

A 43-year-old man with high myopia developed unilateral pigmentary glaucoma with recurrent episodes of painless blurred vision in the left eye following uneventful phacoemulsification. Bilateral cataract surgery was performed with capsular bag implantation of a +4.00 diopter AcrySof MA60 intraocular lens (IOL) (Alcon Laboratories) followed by a neodymium:YAG laser capsulotomy.
