Abstract:
Purpose. To determine diagnostic accuracy of kinetic visual field assessment by Octopus 900 perimetry compared with Goldmann perimetry.Methods. Prospective cross section evaluation of 40 control subjects with full visual fields and 50 patients with known visual field loss. Comparison of test duration and area measurement of isopters for Octopus 3, 5, and 10°/sec stimulus speeds. Comparison of test duration and type of visual field classification for Octopus versus Goldmann perimetry. Results were independently graded for presence/absence of field defect and for type and location of defect. Statistical evaluation comprised of ANOVA and paired t test for evaluation of parametric data with Bonferroni adjustment. Bland Altman and Kappa tests were used for measurement of agreement between data.Results. Octopus 5°/sec perimetry had comparable test duration to Goldmann perimetry. Octopus perimetry reliably detected type and location of visual field loss with visual fields matched to Goldmann results in 88.8% of results(K=0.775).Conclusions. Kinetic perimetry requires individual tailoring to ensure accuracy. Octopus perimetry was reproducible for presence/absence of visual field defect. Our screening protocol when using Octopus perimetry is 5°/sec for determining boundaries of peripheral isopters and 3°/sec for blind spot mapping with further evaluation of area of field loss for defect depth and size.

Abstract:
Background Blepharoplasty has both aesthetic and functional benefits in patients with pseudoptosis; however, previous studies could not demonstrate its beneficial effects quantitatively and objectively. The authors objectively analyzed the visual field before and after surgery and investigated whether measurements of the visual field can be applied as a suitable predictor of surgical outcomes.Methods In total, 18 eyelids in nine patients with pseudoptosis who had undergone simple skin excision blepharoplasty were evaluated prospectively from February to May 2016. The visual fields were analyzed preoperatively and 3 months postoperatively using the Goldmann kinetic perimetry test. The visual field test area was assessed using Adobe Photoshop.Results Blepharoplasty had an average 4.99-fold beneficial effect on the superior visual field. In particular, more improvement was seen in the superior temporal quadrant than in the nasal quadrant. No correlation was found between the preoperative margin-to-reflex distance 1 (MRD1) and the surgical outcome (P=0.119). However, there was a strong correlation between the preoperative superior visual field and the surgical outcome (P=0.001).Conclusions Using the Goldmann kinetic perimetry test, we objectively and quantitatively proved the beneficial effect of blepharoplasty on patients with pseudoptosis. Furthermore, we demonstrated that the preoperative visual field is a better preoperative surgical outcome predictive factor than the preoperative MRD1.

Abstract:
A 78-year-old woman presented with an upper visual field defect in the left eye. On ophthalmic examination, her best-corrected visual acuity (BCVA) was 1.2 in both eyes. Fundoscopy revealed inferior optic disc swelling. Goldmann visual field test showed an upper visual field defect. The patient was diagnosed with nonarteritic anterior ischemic optic neuropathy (NAION) of the left eye and was followed up without treatment. One month after the initial visit, her BCVA decreased to 0.15 in the left eye. Fundoscopy revealed superior optic disc swelling. Goldmann visual field test showed an inferior visual field defect and central relative scotoma. Based on her clinical findings, she was diagnosed with recurrent NAION. Three months after the initial visit, her BCVA was 0.2 in the left eye, and the optic nerve developed atrophy. This case highlights the importance for clinicians to be aware of NAION recurred in the same eye within a short period of time.

Abstract:

 
 
 Introduction and Objective : To assess the relationship between the cup-disc ratio of the optic nerve head and peripapilarry RNFL thickness to the visual field loss in glaucoma patients.
 Methods : Visual field from Goldmann kinetic perimerty and Ocular Computed Tomography (OCT) records from Yap Eye Hospital, Yogyakarta are used to examine the figure of visual field loss in glaucoma patient.
 Result: Broad spectrum of glaucoma-related visual field defects were observed from 73 eyes. The most common visual field defects are arcuate defect (23.3%) and followed by general depression. Arcuate defects can already observable in some patients with cup-disk ratio of 0.5 (30%).Arcuate defect occurs in the average RNFL thickness of 69.90 ?m (46.93-118.77). It appears that the pinhole vision appeared on the average RNFL thickness of 44.23 ?m (25.33-63.13), and temporal RNFL thickness remnant occured at 48.64 ?m (46.22-51.06). RNFL thickness with normal visual field was on the thickness of 107.78 ?m (100.27-115.29).
 Conclusion: Visual field defect that may be observed in glaucoma with Goldmann kinetic perimetry are arcuate defect, and general visual field depression. RNFL thickness may be correlated longitudinally with the worsening of visual field defect.

Abstract:
A 50-year-old man presented with a nasal visual field defect in the left eye. His medical history was unremarkable. On ophthalmic examination, his best-corrected visual acuity (BCVA) was 1.2 in both eyes. Fundoscopy revealed no abnormalities in either eye. Goldmann visual field test showed a nasal visual field defect in the left eye. The patient was diagnosed with NPION of the left eye and was followed up without treatment. However, four days after the initial visit, his BCVA decreased to counting finger in the left eye. Goldmann visual field test showed a complete nasal visual field defect with central absolute scotoma. Following admission, the patient was treated for 3 days with intravenous methylprednisolone pulse therapy. Three months later, his BCVA was improved to 0.8 in the left eye, but central relative scotoma was remained. Six months later, his BCVA was maintained at 0.8, and central relative scotoma was disappeared. However, the optic disc looked diffusely pale in the left eye. This case highlights that steroid therapy is an option for severe cases with posterior ischemic optic neuropathy.

Abstract:
Standard automated perimetry is a standard method of measuring peripheral visual function. Automated static perimetry gained wide acceptance among clinicians due to the test’s high reproducibility and standardization and ability to store, exchange, and statistically analyze digital data. Advances in the computerized visual field assessment have contributed to our understanding of the role that field of vision plays in clinical evaluation and management of patients. The Humphrey Visual Field Analyzer/HFA II-i is the most commonly used automated perimeter in the United States, and the examples in this chapter have been obtained with this instrument. Aubert and Förster in the 1860s developed the arc perimeter, which led to the mapping of peripheral neurologic visual field abnormalities and advanced glaucomatous field defects. Analysis of the central visual field was not seen as clinically important by most clinicians until 1889, when Bjerrum described a detected arcuate paracentral scotoma. Later, Traquair further contributed to kinetic perimetry on the tangent screen. In 1893, Groenouw proposed the term “isopter” for lines with the same sensitivity on a perimetry chart. Rønne further developed kinetic isopter perimetry in 1909 and described the nasal step in glaucoma. Although the first bowl perimeter was introduced in 1872 by Scherk, due to problems with achieving even illumination on the screen, it did not become popular. The version of the bowl perimeter introduced by Goldmann in 1945 became widely accepted and is a significant contribution to clinical perimetry. The Goldmann perimeter incorporated a projected stimulus on an illuminated bowl, with standardization of background illumination as well as size and intensity of the stimulus, and allowed effective use of both static and kinetic techniques. For these reasons, the Goldmann instrument has remained the clinical standard throughout the world until widespread acceptance of automated perimetry. Harms and Aulhorn later designed the Tübingen perimeter with a bowl-type screen exclusively for the measurement of static threshold fields, using stationary test objects with variable light intensity. While excellent threshold measurements were possible with this instrument, the time and effort involved in such measurements prevented this perimeter from becoming widely used.

Abstract:
• Glaucoma results in progressive visual field deterioration, and detecting changes or recording stability in the visual field is important in the management of glaucoma. • Visual field testing is a highly subjective and operator-dependent test. • In patients with glaucoma, the visual field is tested in monocular fashion. •The boundaries of the visual field (in a well-lit environment with an easily visible target) are grossly 60 degrees superiorly, 75 degrees inferiorly, 100 degrees temporally, and 60 degrees nasally. • Basic concept in determination of visual field is “threshold” •Definition of “threshold”: weakest test stimulus that is just visible in a particular location (stimulus intensity at which the patient responds 50% of the time) •Types of visual field testing strategies •Confrontation •Spot testing •Kinetic spot testing •Static spot testing •An initial screening tool to look for large and dense visual field defects that may be present in very advanced glaucoma •Both hands should be used in the testing processed. The patient should occlude the untested eye with the palm of the hand. •If the visual acuity will allow the finger counting technique, all four quadrants may be tested at 3 to 4 feet from the patient at an approximate 45-degree angle holding up either one or two fingers, or a whole hand. • If the visual acuity is HM or LP, then test for light perception in the respective 4 quadrants. • It is important that the patient be able to tell you where the light is located in the field of vision, not simply the presence of light. • Factors that affect the visibility of the spot • Size Intensity • Background illumination Others: color, movement, duration of presentation, attentiveness of the patient, and refractive state of the eye • Kinetic • Usually Goldmann perimetry (though some of the automated machines such as the Octopus will perform kinetic perimetry) • The perimetrist may adjust the location, size, and intensity of the stimulus throughout the test. •Useful in the following cases: Those who need coaching and an altered pace of testing (e.g., elderly, wheelchair-bound, or limited concentration)

Abstract:
Visual fields in the pediatric population are an essential part of the eye exam that remain challenging to even the most experienced clinicians. Becoming educated in the multiple ways a child's visual field can be tested regardless of age and cognitive and physical abilities will allow the clinician to gain better insight into the child's function and in some cases, allow the clinician to identify pathological or neurological anomalies in the visual pathway. Gross visual field or functional visual field extent can be estimated by tests such as confrontation visual field testing, finger counting field testing, and white sphere kinetic perimetry. For threshold measurements of a child's visual fields, the Goldmann perimeter, or the more advanced computerized tests such as the Humphrey perimeter, Octopus perimeter, or frequency doubling technology perimeter can be used. Modifications can be made to certain tests to better suit the child's cognitive and physical abilities. The chapter covers different methods of visual field testing specific for the pediatric population.

Abstract:
Like a painter, the practitioner of perimetry must learn his or her profession from experience. Just as a painting does not spring from the paint and brushes alone, the perimetrist does get his or her diagnosis from just a printout of the field test. Rather, the perimetrist’s experience in interpreting field test results, his clinical skill in examining the validity of the patient’s performance, and his selection of the needed field technique chosen under the appropriate clinical circumstances combine to produce a suitable test and interpretation of results. In this age of computerization, we tend to accept the infallibility of perimetry. It is true that new developments have corrected some of the errors in technique that have been troubling in earlier methods such as the tangent screen and Goldmann perimeter. However, in our rush to embrace these new techniques, we might forget that there is still a place for these older techniques in selected cases. Among other things, these older techniques may allow for a human element to be introduced when the patient is overwhelmed by technology—that is, a well-performed tangent screen is more valuable on a given occasion than a poorly performed computerized field examination. Such circumstances occur almost always with neuro-ophthalmology patients, who are usually ill in other ways than just visually and need more help in performing the test. Most other patients, particularly those with glaucoma, are much more reliable in their responses in using the newer techniques. They frequently start testing at a younger age and do their testing frequently so they become skilled at performing the test. Many neuro-ophthalmologic patients do not have that experience. Interpreting the blind spot remains a standard part of any field examination. Interpreting the blind spot size requires experience. The blind spot may be enlarged because the patient is a slow responder or because a large myopic crescent is present. An important use of measuring the blind spot is to show the patient what a scotoma is and to test his validity of fixation by putting the target in the blind spot from time to time.

Full text
Abstract:
The introduction of automated perimeters has enabled quantitative and standardized testing of the visual fields of patients. But the static perimetry employed in these instruments is too lengthy for young children. Kinetic perimetry is more successful: kinetic fields have been reported in children as young as 2 1/2 years using the Goldmann perimeter (1) and in infants using other kinetic methods (eg 2, 3). Recently, a modification became available for the Humphrey Visual Field Analyzer (Allergan-Humphrey) that enables kinetic perimetry. Potential advantages of the Humphrey kinetic program for pediatric populations are similar to those for adult patients, including minimal examiner skills, standardized kinetic scan parameters, and the possibility of combining kinetic and static testing.

Abstract:
Perimetry techniques are well developed for use in the adult population and provide valuable information about extent and changes in the visual field in ocular and neurologic disease. Kinetic techniques, in which a target of variable size and intensity are moved into the visual field were standardized by Goldmann in 1946 (1). However, most techniques are not approriate for use in young children and infants due to the complex nature of the responses required, but the information provided by perimetry is potentially as vital for pediatric patients as for adults.

Full text
Abstract:
One of the classical symptoms of Retinitis Pigmentosa is the gradual loss of vision in the periphery, first detected as a ring- or horseshoe-shaped scotoma in the mid-periphery. Using a Goldmann perimeter, such a scotoma can first be documented with small targets, e.g. II/4e. Subsequently it slowly increases in density and extent: a V/4e target may reveal the scotoma as much as ten years later than the II/4e target.
