“…Several studies have reported learning effect both in glaucoma (10,(15)(16)28) and healthy individuals (7,9,(13)(14)(28)(29) . Therefore, a change in the threshold sensitivity can be expected between the first two SAP performed by an inexperienced individual.…”

“…It is generally assumed that the individual experience influences the results of automated perimetry (7) . Several studies showed that healthy and glaucomatous individuals can exhibit a learning effect with repeated standard automated perimetry testing (8)(9)(10)(11)(12)(13)(14)(15)(16) . This effect was also demonstrated in short wavelength automated perimetry (17)(18) , flicker perimetry (19) , and frequency doubling perimetry (20)(21)(22)(23)(24)(25) .…”

“…However, studies that evaluate the influence of educational level on learning effect of automated perimetry have not been reported, and few studies analyzed the learning effect using Swedish interactive threshold algorithm (SITA) strategy (9)(10) . The learning effect in perimetry could be influenced by possible associated factors including educational level.…”

Purpose: To evaluate the learning effect in standard automated perimetry using SITA strategy, central 24-2 program, possible associated factors and spatial distribution in individuals with no perimetry experience. Methods: A total of 55 healthy subjects were submitted to Humphrey perimetry in two different sessions in one day. Reliability and global indices, and threshold sensitivity at each point were compared between the two examinations. The influence of potential factors (age, gender, and educational level) and the spatial distribution were evaluated regarding alterations between these two examinations. Results: The duration of the test was longer in the first session (median, 5.7 min; interquartile range [IQR], 1.7 min) than in the second (median, 5.3; IQR, 1.1 min) (p=0.002). The median (IQR) of false negative errors was 2% (6%) in the first examination and 0% (6%) in the second (p=0.04). The mean (standard deviation) in the mean deviation (MD) global index was -2.31 (1.86) dB in the first examination and -1.73 (1.69) dB in the second (p=0.07). No association was observed between the change in MD and age (p=0.29), gender (p=0.69) and educational level (p=0.27). The changes in threshold sensitivity were greater at the peripheral points than at the central points (p<0.001). Conclusion: The threshold sensitivity increased in the second examination compared to the first. No factors were associated with this change. The changes in threshold sensitivity were more evident at the peripheral points. ABSTRACT INTRODUCTION

“…A perimetria de ondas curtas (azul-amarelo), capaz de identificar alterações funcionais três a cinco anos antes da perimetria convencional (7) , tem sido útil para detecção precoce de diversas entidades nosológicas, inclusive algumas desordens neuro-oftalmológicas (8) , mas em diversos trabalhos foram usadas amostras de usuários de tabaco-álcool em processo de reabilitação.…”

“…The inclusion criteria for cataract patients were as follows: patients with cataracts and those over 18 years of age with IOP of <21 mmHg, without perioperative complications, subjected to phacoemulsification by the same surgeon, and absence of ophthalmologic surgeries and/or other ocular previous diseases. In the individuals with glaucoma and cataract, inclusion criteria were cataract present and over 18 years, IOP greater or less than 21 mmHg, using at least two classes of antiglaucomatous medication, excavations larger than 0.7 with loss of neuroretinal rim, 24 open angle with confirmation via gonioscopy, loss of visual field using the Anderson criteria 25 with minimal reproducibility of at least two visual fields, and/or progression. 24 – 26 The exclusion criteria were as follows: patients under 18 years of age, incomplete data in electronic medical records, patients with perioperative or postoperative complications, contact lens users, and/or those with previous ophthalmologic surgeries.…”

ObjectiveEvaluate the pattern of intraocular pressure (IOP) variations through the pneumatic tonometer, between two specific surgical techniques, and the possible variables that may influence the behavior of this pressure.MethodsRetrospective cross-sectional study carried out through the review of electronic medical records of a private ophthalmological reference hospital in the city of Goiânia, Goiás, Brazil, from 2012 to 2016, comprising of a sample of 550 eyes. The analyzed variables were, age, gender, IOP, axis, pachymetry, anterior chamber depth, and axial length.ResultsIn the end, the study consisted of 231 eyes, represented by 179 patients. Of these, 182 eyes were operated on by isolated cataract surgery, with a mean age of 72.0±9.5 years. The combined surgery represented a total of 49 eyes, 34 patients with a mean age of 71.9±8.14 years. There was statistical significance (P<0.05) in correlating the pre- and postoperative IOP values in the 24-hour, 7-, 15-day, and 12-month postoperative periods.ConclusionA standard of variation of IOP was found through the pneumatic tonometer in both surgical techniques, but a more significant reduction was observed in combined surgery than in isolated cataract surgery, and further studies with a greater epidemiological impact are required for confirmation of this conclusion.
