“…These results compare well with earlier studies on treated POAG. [8][9][10] However, these studies 8,9 except the one by Jonas et al 10 have reported IOP fluctuation during office hours in patients with POAG whose visual fields deteriorated despite acceptable office IOP levels or cases when a suspicious optic disc is discovered with normal office IOP. These patient groups may not truly represent treated POAG glaucoma as a whole.…”

“…The treated POAG patients in previous studies on IOP fluctuation either do not truly represent treated POAG glaucoma as a whole or have issues in data collection. [8][9][10] Baskaran et al 6 enrolled study subjects after LPI but before commencement of any medical or surgical treatment. Current consensus recommends LPI in selected PACS eyes.…”

Purpose To evaluate intraocular pressure (IOP) fluctuation during office hours and its predictive factors in untreated primary angleclosure suspects (PACS); post-iridotomy primary angle closure (PAC) and primary angle-closure glaucoma (PACG) eyes with or without IOP-lowering medication(s) as appropriate and medically treated primary open-angle glaucoma (POAG) eyes. Methods One-hundred seventeen eyes (29 PACS, 30 PAC, 28 PACG, and 30 POAG) of 117 patients were included in this crosssectional study. The subjects underwent hourly IOP measurements with Goldmann tonometer from 0800 to 1700 hours. Subjects with PAC and PACG had laser peripheral iridotomy at least 2 weeks prior to the inclusion. SD of office-hour IOP readings was the main outcome measure. Results IOP fluctuation differed between the groups (P = 0.01; Kruskal-Wallis Test). Post hoc Mann-Whitney U-tests showed significantly less IOP fluctuation in PACS compared with PACG (Po0.01). Peak office-hour IOP was observed in the morning in untreated subjects and in the early afternoon in treated subjects. A stepwise linear regression model identified the presence of peripheral anterior synechiae (PAS), thickness of lens, large vertical cup-to-disc ratio (VCDR), and PAC category as significant predictive factors associated with office-hour IOP fluctuation. Conclusions Diurnal IOP fluctuation in asymptomatic PACSs was less than that in treated PACG subjects and was at least comparable to that in treated PAC and POAG subjects. The greater the amount of PAS, the thicker the lens, the larger the VCDR, the greater was the IOP fluctuation during office hours.

“…We did not control for diurnal variation in IOP, which has been reported to result in a mean range of 5.8 mmHg in patients with open-angle glaucoma. 24 Although our three IOP measurements taken at each baseline visit were from a 2 to 3 hour period of time, the time of day of these visits may have contributed to variation between visits.. A number of factors were associated with the mean IOP obtained in these newly diagnosed glaucoma patients prior to the onset of treatment. Older age was associated with lower IOP in our patients, which differs from that found in many population studies.…”

Methods-After randomization to initial surgery or medications, patients were followed at sixmonth intervals. IOP was measured by Goldmann applanation tonometry. Predictive factors for IOP at baseline and during follow-up were analyzed using linear mixed models. Main Outcome Measure-IOP at baseline and during follow-up.Results-The mean baseline IOP was 27.5 mmHg (standard deviation, 5.6 mmHg). Predictive factors for higher baseline IOP included younger age (0.7 mmHg per 10 years), male sex (2.4 mmHg higher than females), pseudoexfoliative glaucoma (5.4 mmHg higher than primary OAG), and pupillary defect (2.2 mmHg higher than those without a defect). During nine years of follow-up, both surgery and medications dramatically reduced IOP from baseline levels, but the extent of IOP reduction was consistently greater in the surgery group. Over follow-up years 2-9, mean IOP was

21 mmHg) da curva tensional diária e minicurva foram comparados, assim como o horário de ocorrência dos picos. RESULTADOS: A Po média foi maior no glaucoma primário de ângulo aberto do que nos suspeitos tanto na minicurva como na curva tensional diária Quando comparadas, a curva tensional diária apresentou médias de Po maiores que a minicurva. A medida das 6 horas foi maior quando feita com o paciente deitado. A minicurva não detectou 60,42% dos picos nos pacientes com glaucoma primário de ângulo aberto e 88,24% dos picos nos suspeitos. CONCLUSÃO: 1. A curva tensional diária detectou mais picos pressóricos do que a minicurva; 2. A média de Po das 6 horas foi maior com o paciente deitado; 3. A Po das 6 horas com o paciente deitado foi maior do que a Po média da curva tensional diária e da minicurva.]]>
