Astigmatism and diagnostic procedures.

Astigmatism represents an inability of the cornea and lens to provide a sharp image onto the retina. Correcting astigmatic errors, whether congenital, contact lens induced or surgically induced, is now an integral part of modern cataract and refractive procedures. Development of modern technology has enabled accurate diagnosis and perfect opportunities for correction; however, while cataract and keratorefractive surgery have come a long way in the last decade, the treatment and diagnosis of astigmatism continue to challenge ophthalmologists.

Macular thickness and volume parameters measured using optical coherence tomography (OCT) for evaluation of glaucoma patients.

The aim of this study was to evaluate macular thickness parameters in glaucoma patients and to compare them to normal subjects using Optical Coherence Tomography (OCT). This prospective, observational study included 20 primary open angle glaucoma patients (POAG) and 20 healthy subjects in control group. Exclusion criteria were diabetes and other macular pathology, like age-related macular degeneration, macular oedema, central serous retinopathy and high myopia >4.

Differential diagnosis of the scalp hair folliculitis.

Safety and efficacy of monotherapy change to fixed combination (travoprost 0.004%/timolol 0.5%) in 6 months follow up period.

Purpose: To assess the safety and efficacy of changing antiglaucoma therapy to the travoprost 0.004%/timolol 0.5% (TTFC) fixed combination from previous monotherapies.

Perifolliculitis capitis abscedens et suffodiens in a caucasian: diagnostic and therapeutic challenge.

Perifolliculitis capitis abscedens et suffodiens or dissecting cellulitis of the scalp is a rare, chronic destructive folliculitis of the scalp, characterized by painful nodules, purulent drainage, sinus tracts, keloid formation and cicatricial alopecia. The cause of the disease is unknown, but it is similar in many features to hidradenitis suppurativa and acne conglobata.
