“…The ACA in each quadrant was graded using the Scheie grading system, which is based on anatomical structures observed during gonioscopy (grade IFvisible ciliary body, grade IIFvisible scleral spur, grade IIIFvisible anterior trabecular meshwork, grade IVFangle structures not visible). 7 Anterior segment optical coherence tomography Anterior segment imaging was performed using the commercially available Visante-OCT (model 1000, software version 1.0, Carl-Zeiss Meditec) and SL-OCT devices (SL-OCT software version 1.1, Heildelberg Engineering). The details of AS-OCT imaging technology have been described previously.…”

“…These include the Scheie, Shaffer, and Spaeth systems, which describe several characteristics of the drainage angle, including the proximity of the peripheral iris and trabecular meshwork on the basis of visibility of anatomical landmarks, or estimation of the angle width in degrees. [45][46][47] These gonioscopic grades provide an index of the likelihood of closure. 16 A dichotomous classification of drainage angle width (and perceived risk of closure) is used in epidemiological research.…”

In contrast to the pattern of disease in Europeans, primary angle closure has a higher prevalence and tends to be asymptomatic in East Asians. The higher prevalence is attributed to differences in anterior chamber and angle anatomy. Several studies suggest that central anterior chamber depth is shallower in East Asians than in Europeans, although this is not universally accepted. It is debated whether pupil block is the predominant mechanism of angle closure in Asian people. Meaningful comparison between studies is currently hindered by differences in patient selection, examination technique, and case definition; however, the major scientific deficiency is the paucity of prospective followup data to give an insight into natural history of the disease. This review examines the data on prevalence, risk factors, and mechanism of angle closure. Special consideration is given to limitations of methodology in research to date, with the intention of developing more robust data in future studies.

“…For each patient we recorded the following characteristics: Age, ethnicity, sex, side treated (left/right), type of glaucoma, irido-corneal angle pigmentation (grade 0 to 4 according to the Scheie classification [10]) pachymetry and history of filtration surgery.…”

Purpose: The objective of this study was to observe the 1-year pressure gain in a consecutive series of glaucoma patients treated by selective laser trabeculoplasty, along with the clinical and technical characteristics that influence the evolution of intraocular pressure after treatment. Materials and methods:We carried out a retrospective study of all patients treated in the ophthalmology department of Nancy University Hospital between January 2015 and March 2016. Treatment was performed with a Q-Switched, frequency doubled Nd: YAG laser (Solutis -Quantel Medical, France), over 180° or 360° of the trabecular meshwork. The mean decreases in Intraocular pressure and the success rate (defined as a decrease in intraocular pressure of ≥ 20% at 1 year without increasing the medical treatment) were calculated. The impact of the different clinical and technical characteristics of each case on the decrease in pressure was also studied by bivariate analysis. Results:One hundred and nineteen eyes, in 78 patients, were included. The decrease in IOP at 1 year was in mean of 4.2 mmHg (Standard Deviation = 5.37), and of 19.6% from baseline. The success rate was 46.7%. Only two minor and reversible complications occurred during the follow-up period.Discussion: Selective trabeculoplasty is currently a therapeutic option called-upon at different stages in the progression of glaucoma. The duration of efficacy of this laser therapy, and the retreatment frequency are yet to be defined.
