Ocular injuries associated with motor vehicle accidents: long term effects on quality of life.

PURPOSE: To describe the prevalence and outcome of motor vehicle accidents-associated ocular injuries. METHODS: A survey of patients who presented to the emergency room at a level 1 trauma center with motor vehicle accidents-associated ocular injuries. A patient questionnaire and review of clinical notes were conducted for all patients. RESULTS: Of 274 motor vehicle accident victims with ocular injuries who presented to the emergency room, 40 (15%) responded to the survey. Over half of them were driving a vehicle, and most reported wearing a seat belt or a helmet. Most ocular injuries were mild. The most common injuries were bone fractures, subconjunctival hemorrhage, eyelid involvement and corneal injury. Most respondents had no change in vision and perceived their ocular involvement as a minor part of their injury. Most respondents returned to work and to driving within a year. CONCLUSION: Our study sheds light on the details and extent of ocular involvement and the visual ability to perform daily activities following motor vehicle accidents.

Optical Coherence Tomography Angiography for the Differentiation of Glaucoma from Pituitary Macroadenoma Related Optic Disc Measurements.

OBJECTIVE: To determine the potential of optical coherence tomography (OCT) and OCT angiography (OCTA) to distinguish between glaucoma and pituitary macroadenoma by optic disc appearance. METHODS: This prospective case-control study comprised 31 patients: 23 with glaucoma (18 male, 5 female) and 8 with pituitary macroadenoma and chiasmatic compression (3 male, 5 female). The corresponding mean ages were 72.8 years (range 58-90) and 60.7 years (range 43-73). All participants underwent complete ophthalmological examination, spectral domain OCT and OCTA, and visual field testing. Clinical, imaging, and visual field results were compared between the groups. RESULTS: On OCT analysis, the glaucoma group had relatively lower peripapillary retinal nerve fiber layer (RNFL) thickness (65.79 ± 15.46, 86.0 ± 11.37, respectively, P = .002) and lower rim area (1.00 ± 0.22 mm2 and 1.2 ± 0.15 mm2, respectively, P = .005). On OCTA, peripapillary vessel density was significantly lower in all quadrants in the glaucoma group. The significance of these between-group differences was maintained when patients were stratified by visual field mean deviation. CONCLUSIONS: This is the first comparative analysis of optic disc morphology between glaucoma and pituitary macroadenoma using combined OCT and OCTA. The results yielded lower peripapillary RNFL thickness, lower rim area, and lower peripapillary vessel density in the glaucoma group. These parameters may aid in the initial differentiation between these two optic neuropathies.

Peripheral Exudative Hemorrhagic Chorioretinopathy with and without treatment-Clinical and multimodal imaging characteristics and prognosis.

PURPOSE: To describe clinical and imaging characteristics of patients with Peripheral Exudative Hemorrhagic Chorioretinopathy (PEHCR), prognosis and treatment response. METHODS: In this retrospective cohort study medical records of patients diagnosed with PEHCR in a tertiary medical center between 2008 and 2018 were reviewed. Collected data included demographics, medical history, ophthalmologic examination and multi-modal imaging including fundus autofluorescence, optical coherence tomography (OCT), ultrasound (US), fluorescein angiography and indocyanine green angiography when available. Bevacizumab treatment results were analyzed when applied. RESULTS: 35 eyes of 32 patients were included, with a female predominance (56.25%) and an average age of 79.0±9.87 years at presentation. Most common OCT and US findings were subretinal mass (68.75%), pigment epithelial detachment (30.00%) and atrophic changes (21.86%). Median follow-up period was 18.00 months (range 0-102). Visual acuity (VA) remained stable (39.29%) or improved (25.00%) in most cases available for follow-up. Treatment with intravitreal bevacizumab induced a statistically significant clinical resolution in 88.89% of eyes available for follow-up (8/9 eyes) (p = 0.02). CONCLUSIONS: PEHCR is presented with high clinical variability and generally good prognosis. This is the first publication demonstrating a statistically significant clinical resolution of disease following intravitreal bevacizumab injections.

Periodic Eye Examinations among Ophthalmologists: Attitudes, Performance, and Barriers for Compliance.

BACKGROUND: Preventive eye care is a preferred practice that includes recommended regular eye examinations, which is not always followed. OBJECTIVE: This study examined attitudes of ophthalmologists toward routine eye examinations, analyzed compliance with their own eye examinations, and described reasons for non-compliance. METHODS: This was a cross-sectional study involving an online survey, sent to all members of the Israeli Ophthalmological Society (IOS) asking their personal opinions concerning routine eye care, self-performance of these tests, and reasons for non-compliance. RESULTS: A total of 243 responses were received (59% males, mean age 52 years) representing 40% of IOS members. 98% of respondents think that adults should be routinely screened for eye diseases, most commonly annually (52%) or every two years (36%); however, only 55% of ophthalmologists reported having themselves a routine eye check in the past 3 years, which is significantly lower than their spouse (68%, P = 0.003). Recommendations for routine eye examinations were always higher than their actual performance regardless of the responding ophthalmologists' gender, age or country of birth. Furthermore, female gender was found to be a negative predictor of having these examinations. Pupil dilation was performed in 38% of ophthalmologists' testing, even though 80% of them think it is necessary for a complete examination. 'Lack of time' (35%) and 'forgetfulness' (31%) were the main reasons provided by ophthalmologists as an explanation for not having regular eye testing. CONCLUSIONS: Ophthalmologists typically recognize the importance of preventive eye care, recommending periodic eye examinations for their patients; however, self-performance of these evaluations by the ophthalmologists themselves is much lower.

Incidence of non-glaucomatous ocular disease in patients with asymmetric optic disc cupping.

PURPOSE: To evaluate the incidence of non-glaucomatous ocular disease in patients with asymmetric optic disc cupping. METHODS: A retrospective case series, including consecutive patients with cup-to-disc ratio (CDR) asymmetry greater than 0.2. All patients underwent a complete neuro-ophthalmological examination, automated perimetry with the Humphrey 24-2 visual fields program. Retinal nerve fibre layer thickness was measured by optical coherence tomography (OCT). The results of neuroimaging, macular OCT and blood tests were recorded as well. Patients were assigned a diagnosis of glaucomatous optic neuropathy (GON) or non-glaucomatous disease (NGD). The main outcome measure was the rate of non-glaucomatous ocular disease. RESULTS: A total of 120 (67 males) patients with a mean age of 71.1 ± 12.5 years met the inclusion criteria and were included in this study. The mean asymmetry in CDR between the eyes was 0.3 ± 0.13 (range, 0.2-0.9). Twenty patients (16.6%) had a visual field defect not typical for glaucoma and positive relative afferent pupillary defect was found in 24 patients (20%). Six patients were found to have newly diagnosed non-glaucomatous ocular disease: maculopathy in three patients, retinopathy in one patient and traumatic optic neuropathy in two patients. Patients with NGD were significantly younger than the patients with GON (59.8 ± 23.3 vs. 71.3 ± 11.5 years, P = 0.001). Optic disc pallor was found in 4/93 patients with glaucoma compared to 3/6 with newly diagnosed non-glaucomatous disease (4.7% vs. 50.0%, P = 0.03). CONCLUSIONS: Asymmetric optic disc cupping can be associated with non-glaucomatous disease and may warrant neuro-ophthalmological evaluation, especially in younger patients or those with optic disc pallor.

Avoiding Diagnostic Lens Fogging During the COVID-19 Era.

Since the advent of COVID-19, the patient's use of a face mask hampers our visibility because there is a marked fogging in our view produced by the warm breath that escapes from the top of the patient's mask and lands on the cooler surface of the lens. This panorama is sometimes so frustrating that we have been forced to ask our patients to remove their facemasks while examined, increasing the risk of being infected. We consider it essential to share this small pearl technique that we can apply in order to avoid fogging during the examination; it is easy, and most importantly, without putting at risk the patient or doctor's health. In our opinion, this is the first material to propose this technique.

Short-term anterior chamber inflammation in phacoemulsification with and without Ex-Press glaucoma implant.

PURPOSE: The aim of this study was to investigate the incidence of clinically significant anterior chamber inflammation in a combined surgery, namely, phacoemulsification and Ex-Press miniature glaucoma device implantation, compared to phacoemulsification alone. METHODS: A retrospective comparative study of a consecutive series of 210 participants above 18 years of age diagnosed with significant cataract and who required glaucoma surgery, namely, Ex-Press miniature glaucoma device implantation or cataract alone in one or both eyes. All were operated on by a single experienced glaucoma surgeon in a single medical center. A total of 231 eyes were included in this study. All cases underwent an uneventful surgery and were examined the day following the surgery for visual acuity, intraocular pressure, and signs of excessive anterior chamber inflammation (Standardization of Uveitis Nomenclature grading ⩾ 3). RESULTS: The combined group included 55 eyes of 51 patients, of whom 15 (27.3%) demonstrated excessive anterior chamber inflammation. The phacoemulsification group included 176 eyes of 159 patients, of whom 12 (6.7%) demonstrated excessive anterior chamber inflammation. Visual acuity and intraocular pressure measurements showed no statistically significant difference between the two groups. CONCLUSION: The Ex-Press glaucoma device is efficient, safe, and known for its inert nature. However, combination of this procedure with phacoemulsification surgery might result in a condition encouraging excessive inflammation, which eventually could lead to excessive anterior chamber inflammations if not treated vigorously. Emphasizing and recognizing the risks, especially in glaucoma patients, is important.

Optical Coherence Tomography May Help Distinguish Glaucoma from Suprasellar Tumor-Associated Optic Disc.

PURPOSE: This study aimed to differentiate patients with bilateral disc cupping associated with suprasellar tumor from patients with open-angle glaucoma by analyzing differences in optical coherence tomography (OCT) of the optic nerve. METHODS: In this retrospective cross-sectional study, we collected data from the eyes of 25 patients with suprasellar craniopharyngioma or pituitary macroadenomas (group 1) and 35 patients with primary open-angle glaucoma (POAG) (group 2), seen between 2001 and 2015, all with a visual acuity of ≥20/40, for whom Stratus Time-Domain (TD) optic nerve OCT scans were available. The main outcome measures were the retinal nerve fiber layer (RNFL) thickness, disc area, cup volume, cup/disc ratio, and rim area. RESULTS: A total of 31 patients met the inclusion criteria and were included in the study: 16 with suprasellar tumors and 15 with POAG. Both groups were similar in terms of gender and age (P > 0.05). The glaucoma group had a borderline greater total RNFL thickness (74.2 µm versus 62.8 µm, P=0.07), disc area (2.70 mm2 versus 2.16 mm2, P=0.004), and cup volume (0.20 mm3 versus 0.08 mm3, P=0.02). In multivariate, glaucoma was associated with increased total RNFL thickness (OR = 1.116 per µm, P=0.008), increased disc area (OR = 2.402 per 100 µm2, P=0.002), and decreased rim area (OR = 0.272 per 100 µm2, P=0.011). Of these, the parameter with the greatest AUC was the disc area (AUC = 0.79). Using the Youden index, the optimal cut-off point identified for stratification was a disc area greater than 2.33 µm2. CONCLUSIONS: In patients with bilateral disc cupping, a decreased total RNFL thickness and smaller disc area seem to be associated with suprasellar tumors (when compared with open-angle glaucoma). These findings may aid in early diagnosis of cupping from suprasellar tumors, before compressive visual loss occurs.

The effect of reduced contrast sensitivity on colour vision testing.

OBJECTIVE: To assess the effect of reduced contrast sensitivity on three commonly used colour vision tests in order to establish key discrepancies that may be relevant for clinical practice. METHODS: A prospective non-interventional clinical study of colour vision testing using three commonly used devices: Ishihara and Hardy-Rand-Rittler (H-R-R) pseudoisocochromatic plate tests, and Farnsworth D-15 arrangement test performed under progressively reduced contrast sensitivity conditions achieved with a neutral density filter bar. RESULTS: The Pelli-Robson contrast sensitivity (PRCS) at which 5% of the population should first experience a 10% reduction in colour vision testing from baseline was calculated for each of the three colour vision devices: Farnsworth D-15 test: 1.81 log contrast sensitivity (CS), H-R-R test: 1.69 log CS, and Ishihara test: 1.34 log CS. Single factor repeated measures analyses, conducted separately at each contrast sensitivity level, revealed no difference between the colour vision testing devices at PRCS ≥1.80 log CS (P ≥ 0.367). However, in all PRCS ≤1.65 log CS, the differences were statistically significant (all P ≤ 0.004), demonstrating a significantly lower percentage of errors in the Ishihara test compared with both the Farnsworth D-15 (P < 0.023) and H-R-R (P < 0.035) tests. CONCLUSIONS: At high contrast sensitivities, all colour vision tests function almost equally; however, at decreased levels of contrast sensitivity, H-R-R and Farnsworth D-15 are more greatly affected.

Chairs of United States Academic Ophthalmology Departments: A Descriptive Analysis and Trends.

PURPOSE: To characterize and analyze the profile of United States (US) academic ophthalmology department chairs. DESIGN: Cross-sectional study. METHODS: Setting: Web search of publicly accessible sources. STUDY POPULATION: One hundred and eleven US ophthalmology chairs. MAIN OUTCOME MEASURES: Demographic and academic data. RESULTS: Of the 111 chairs reviewed, 90% are male. Mean age of chairs is 59 years, and mean age at time of appointment is 47 years. Ninety-two percent of chairs graduated from an American medical school. Twenty-eight percent of chairs also have additional graduate degrees: 8% a Doctor of Philosophy (PhD) degree, 15% a master's degree, and 5% both. Ninety-five percent of chairs completed a clinical fellowship, most frequently in cornea (25%), vitreoretinal surgery (23%), and glaucoma (21%). The 3 programs that trained the largest number of chairs are Massachusetts Eye and Ear Infirmary, Wilmer Eye Institute, and Bascom Palmer Eye Institute. Thirty-two percent of chairs were previously trained in the program they currently head, more commonly as a resident (28%) than as a fellow (5%). The estimated mean number of publications per chair is 108 (range, 0-850) and the mean h-index is 24. Twenty-seven programs exchanged chairs from 2014 to 2017. The characteristics of appointed chairs are no different than those of recently retired chairs. CONCLUSIONS: Ophthalmology chairs remain predominately male, most often specializing in cornea, vitreoretinal surgery, or glaucoma. Most chairs tend to be prolific authors whose careers have placed an emphasis on research; however, a lack of demonstrated research experience does not preclude chairmanship in certain US programs.

Retinal Penetration of Intravitreally Injected Tissue Plasminogen Activator: A Rat Model Study.

PURPOSE: To determine whether intravitreal unconjugated tissue plasminogen activator (tPA) (alteplase) can penetrate the intact neural retina and reach the subretinal space in an experimental model. METHODS: This study was performed in 24 Sprague-Dawley rats aged 12 weeks. Under general anesthesia, the right eye was injected with either 0.75 µg of 3 µL tPA (14 rats; study group) or saline (10 rats, control group) into the vitreous. Animals were euthanized at 3, 24, and 48 h. The eyes were enucleated, and cryosections were prepared for immunofluorescence staining. Goat anti-tPA antibody was used to detect tPA. RESULTS: In the study group, staining for tPA was detected in the deep retinal layers in all eyes. The staining was deeper and more intense at 3 and 24 h than at 48 h. There was no tPA staining in the retina of eyes injected with saline. CONCLUSIONS: This experimental study shows that unconjugated tPA administered into the vitreous is capable of penetrating the deep retinal layers and the subretinal space. These findings suggest that further clinical research is warranted on the benefits of intravitreal tPA in the treatment of submacular hemorrhage.

Mobile Laser Indirect Ophthalmoscope: For the Induction of Choroidal Neovascularization in a Mouse Model.

PURPOSE: This study aims to evaluate and standardize the reliability of a mobile laser indirect ophthalmoscope in the induction of choroidal neovascularization (CNV) in a mouse model. MATERIALS & METHODS: A diode laser indirect ophthalmoscope was used to induce CNV in pigmented male C57BL/6J mice. Standardization of spot size and laser intensity was determined using different aspheric lenses with increasing laser intensities applied around the optic disc. Development of CNV was evaluated 1, 5, and 14 days post laser application using fluorescein angiography (FA), histology, and choroidal flat mounts stained for the endothelial marker CD31 and FITC-dextran. Correlation between the number of laser hits to the number and size of developed CNV lesions was determined using flat mount choroid staining. The ability of intravitreally injected anti-human and anti-mouse VEGF antibodies to inhibit CNV induced by the mobile laser was evaluated. RESULTS: Laser parameters were standardized on 350 mW for 100 msec, using the 90 diopter lens to accomplish the highest incidence of Bruch's membrane rupture. CNV lesions' formation was validated on days 5 and 14 post laser injury, though FA showed leakage on as early as day 1. The number of laser hits was significantly correlated with the CNV area. CNV growth was successfully inhibited by both anti-human and mouse VEGF antibodies. CONCLUSION: The mobile laser indirect ophthalmoscope can serve as a feasible and a reliable alternative method for the CNV induction in a mouse model.

Corneal cut closure using temperature-controlled CO2 laser soldering system.

We aimed to evaluate the effectiveness of temperature-controlled laser soldering for repair of large perforated corneas in a porcine model. Eight Yorkshire pigs aged 6 months underwent 6-mm-deep 180° crescent-shaped trephination of the central corneas. Right corneal injuries were repaired by placement of 47 % bovine albumin along the cut followed by CO2 laser soldering (power density 16 W/cm(2)) to a target temperature of 65(°). Left corneal injuries were repaired with 10/0 nylon sutures. The groups were compared for operative time, leakage, and histopathological findings. Mean tissue temperature was 63 ± 4 °C. Mean operative time was 31.57 ± 2.8 min in laser-soldered eyes and 41.38 ± 2.3 min in controls (p < 0.0001, unpaired Student's t test). Compared to controls, the soldered corneas had less neovascularization, complete re-epithelization, and mild stromal inflammation. There was no leakage in either group. Combined CO2 laser and radiometer is effective for the in vivo repair of corneal cuts. These results have important implications for modern corneal surgery. Further studies are needed in the clinical setting.

Mutations in TAX1BP3 cause dilated cardiomyopathy with septo-optic dysplasia.

We describe a Bedouin family with a novel autosomal recessive syndrome characterized by dilated cardiomyopathy and septo-optic dysplasia. Genetic analysis revealed a homozygous missense mutation in TAX1BP3, which encodes a small PDZ domain containing protein implicated in regulation of the Wnt/ß-catenin signaling pathway, as the causative mutation. The mutation affects a conserved residue located at the core of TAX1BP3 binding pocket and is predicted to impair the nature of a crucial hydrophobic patch, thereby interrupting the structure and stability of the protein, and its ability to interact with other proteins. TAX1BP3 is highly expressed in heart and brain and consistent with the clinical findings observed in our patients; a knockdown of TAX1BP3 causes elongation defects, enlarged pericard, and enlarged head structures in zebrafish embryos. Thus, we describe a new genetic disorder that expands the monogenic cardiomyopathy disease spectrum and suggests that TAX1BP3 is essential for heart and brain development.

CO2 laser welding of corneal cuts with albumin solder using radiometric temperature control.

PURPOSE: To examine the efficacy and reproducibility of CO2 laser soldering of corneal cuts using real-time infrared fiber-optic radiometric control of tissue temperature in bovine eyes (in vitro) and to evaluate the duration of this procedure in rabbit eyes (in vivo). METHODS: In vitro experiment: a 6-mm central perforating cut was induced in 40 fresh bovine eyes and sealed with a CO2 laser, with or without albumin soldering, following placement of a single approximating nylon suture. A fiber-optic radiometric temperature control system for the CO2 laser was used. Leaking pressure and histological findings were analyzed and compared between groups. In vivo experiment: following creation of a central perforation, 6 rabbit eyes were treated with a CO2 laser with albumin solder and 6 rabbit eyes were treated with 10-0 nylon sutures. The amount of time needed for completion of the procedures was compared. RESULTS: In vitro experiment: effective sealing was achieved by CO2 laser soldering. Mean (± SD) leaking pressure was 109 ± 30 mm Hg in the bovine corneas treated by the laser with albumin solder compared to 51 ± 7 mm Hg in the sutured control eyes (n = 10 each; p < 0.001). Mean leaking pressures were much lower in the corneal cuts sealed only with the laser without albumin solder (48 ± 12 mm Hg) and in the cuts sealed only with albumin without laser welding (6.3 ± 4 mm Hg) than in the cuts treated with laser welding and albumin solder. In vivo experiment: mean surgical time was 140 ± 17 s in the laser-treated rabbits compared to 330 ± 30 s in the sutured controls (n = 6; p < 0.001). A histopathological study of the rabbit corneas 1 day after laser soldering revealed sealed corneal edges with a small gap bridged by coagulated albumin. The inflammatory reaction was minimal in contrast to the sutured controls. No thermal damage was detected at the wound edges. CONCLUSIONS: CO2 laser soldering combined with the fiber-optic radiometer is an effective, reliable, and rapid tool for the closure of corneal wounds, and holds advantages over conventional suturing in terms of leaking pressure and surgical time.

Digital versus film stereo-photography for assessment of the optic nerve head in glaucoma and glaucoma suspect patients.

PURPOSE: One of the leading methods for optic nerve head assessment in glaucoma remains stereoscopic photography. This study compared conventional film and digital stereoscopy in the quantitative and qualitative assessment of the optic nerve head in glaucoma and glaucoma suspect patients. METHODS: Fifty patients with glaucoma or suspected glaucoma underwent stereoscopic photography of the optic nerve head with a 35-mm color slide film and a digital camera. Photographs/images were presented in random order to 3 glaucoma specialists for independent analysis using a standardized assessment form. Findings for the following parameters were compared among assessors and between techniques: cup/disc (C/D) ratio, state of the optic rim, presence of peripapillary atrophy and appearance of the retinal nerve fiber layer, blood vessels, and lamina cribrosa. The film-based and image-based diagnoses (glaucoma yes/no) were compared as well. RESULTS: Despite high level of agreement across graders using the same method for the horizontal and vertical C/D ratio, (intraclass correlations 0.80 to 0.83), the agreement across graders was much lower for the other parameters using the same method. Similarly the agreement between the findings of the same grader using either method was high for horizontal and vertical C/D ratio, but low for the other parameters. The latter differences were reflected in the disagreement regarding the final diagnosis: The diagnoses differed by technique for each grader in 18% to 46% of eyes, resulting in 38.5% of eyes diagnosed with glaucoma by film photography that "lost" their diagnosis on the digital images, whereas 18.7% of eyes diagnosed as nonglaucomatous by film photography were considered to have glaucoma on the digital images. CONCLUSIONS: Although there is consistency between 35-mm film stereoscopy and digital stereoscopy in determining the cup/disc (C/D) ratio, in all other parameters large differences exist, leading to differences in diagnosis. Differences in capturing images between digital and film photography may lead to loss of information and misdiagnosis. Further studies are needed to determine the reliability of the new digital techniques.

The prevalence of polycystic ovary syndrome in women with idiopathic intracranial hypertension.

Purpose. The purpose of this study is to re-evaluate whether the prevalence of polycystic ovary syndrome (PCOS) amongst women with idiopathic intracranial hypertension (IIH) is higher than in the general population using the NIH criteria. Methods. We included all consecutive women with IIH of child-bearing age seen at a hospital-based neuro-ophthalmology clinic between the years 2000-2005. All consenting women included in this study filled-out a screening questionnaire aimed at identifying women at risk for PCOS. The endocrinologist examined each patient suspect of PCOS as well as their biochemical results and diagnosed PCOS according to NIH criteria. The prevalence of PCOS in these women with IIH was compared with the reported prevalence of PCOS in the general population. Results. Out of 58 women with IIH who completed the study, definite PCOS was diagnosed in nine women (9/58; 15.5%). We found a significantly higher prevalence of PCOS using the NIH criteria among the IHH study group (15.5%, P = 0.001) compared to the general population (8.7%). Conclusions. The prevalence of PCOS is higher among patients with IHH, compared to the general population. We suggest a novel screening questionnaire to aid in the identification of women with IIH at risk for PCOS.

Large-scale survey of unselected automated visual fields in a major reading center: patterns and data analysis.

A prospective, randomized study was conducted to survey a large number of automated perimetry examinations in a central reading institute, obtaining practical information on unselected referred patients and their clinician "consumers". Visual field records of 1041 patients were obtained, each evaluated by one of three glaucoma specialists. Statistical analysis was applied on demographics, physician characteristics, test reliability and visual field scores. Reliability was scored on a scale of 1 (excellent) to 5 (uninterpretable). Data from earlier examinations of these patients was also analyzed. The large majority of patients (70.4%) were referred due to glaucoma, ocular hypertension or suspected glaucoma. Most of the patients had threshold strategies: FastPac 24-2 or 30-2 (88.9%), Full Threshold (0.7%), and 10-2 (0.5%). In only 7 patients was short-wavelength automated perimetry (SWAP) performed. The Swedish Interactive Testing Algorithm (SITA) was applied in 1.0% of cases. More than half (56.8%) of the population had a reliability score of 1, and 22.7% had a score of 2, indicating a valid result for 79.4% of patients, providing clinically useful information. Linear regression analyses indicated that the Mean Defect was a better predictor of the visual field score than the Corrected Pattern Standard Deviation (CPSD), for the entire group and for each visual field score subgroup.
