[Practical assessment. Early-stage or advanced glaucoma].

In the case of early-stage or advanced glaucoma, the major problem is no longer diagnostic, but evaluating its response to treatment. Other than questioning the patient, assessment includes measuring visual acuity and intraocular pressure, examining the anterior segment and the optic disc, and finally an analysis of the visual field. This latter examination remains the least contestable, although subjective, in evaluating how a confirmed case of glaucoma is evolving. Examination of the optic disc using stereoscopy should include a drawing or, at best, a photograph. Finally, three recent analyzers are available and being evaluated: HRT II, GDx, OCT-3. Depending on the results (of intraocular pressure, the visual field and the optic disk), treatment can be modified and/or the assessment completed.
