Visual field examination using a video projector: comparison with Humphrey perimeter

Introduction and Objective: Glaucoma is the leading cause of global irreversible blindness, signed by glaucomatous optic neuropathy related to visual field defect. The purpose of the study is comparing visual field defect examination using HVFA to Amsler Grid in glaucoma patient at dr. Kariadi Hospital. Methods: This is a cross-sectional study. Amsler Grid were performed to the patients who have reliable HVFA at last 6 months and presented as descriptive analytic results. Result: There were 40 eyes involved in this study from 27 patients (15 men, 12 women), 26-68 years old and visual acuity 1/60-6/6. Seventeen eyes showed visual field defect in HVFA and Amsler Grid had average MD - 24.97 dB, CDR 0.89 and RNFL thickness 51.74. We found that 11 eyes didn’t showed in both of examination had average MD -8.06, CDR 0.63 and RNFL thickness 103.23 and those parameters are significantly different to the 17 eyes before (p<0.05). Data from 12 eyes that showed visual field defect only one of examination (9 only in HVFA and 3 in Amsler Grid) didn’t show difference statistically each other. Conclusion: HFVA and Amsler Grid seemed to be comparable in detecting visual field defect in advanced glaucoma.

Necrosis Factor

Purpose: Demyelinizing neurological disease is a rare complication after treatment with tumor necrosis factor (TNF)α antagonists. We report on a case of multiple sclerosis after TNFα antagonist treatment and discuss its differential diagnosis. Methods: This is an observational case study. Results: A 48-year-old male was referred to Ophthalmology in January 2015 for an absolute scotoma in the superior quadrant of the visual field in his right eye. Visual acuity was 20/50 in the right eye and 20/20 in the left. Fundus examination was unremarkable bilaterally. Spectral domain optical coherence tomography revealed a normal macular retina structure. Visual field examination revealed a superior hemianopsia in the right eye. Head magnetic resonance imaging showed findings compatible with optic neuritis. The visual evoked potentials confirmed the presence of optic neuritis. The patient had been under therapy with adalimumab since January 2014, for Crohn’s disease. Suspension of adalimumab was recommended, and it was substituted with tapered deltacortene, from 1 mg/kg/day. After 1 month, the scotoma was resolved completely. Conclusions: TNFα antagonists can provide benefit to patients with inflammatory autoimmune diseases. However, they can also be associated with severe adverse effects. Therefore, adequate attention should be paid to neurological abnormalities in patients treated with TNFα antagonists.

Aim: The aim of this study is to assess Scheimpflug topographic elevation maps in patients with POAG and correlate the results with their perimetric changes. Methods: This was an analytical observational cross-sectional study. The study included 130 eyes of 70 subjects which were divided into 78 eyes of 44 patients diagnosed with POAG and 52 eyes of 26 control subjects. Measurement of IOP, visual field examination in patients with POAG using Humphrey Field Analyzer (2003 Carl Zeiss Meditec), Germany were done. Subjects were scanned using TMS-5 topographer (Topographic Modeling System, version 5. Tomey Corp. Nagoya, Japan) to measure central corneal thickness, mean anterior keratometry, maximum anterior and posterior topographic elevation maps in the central 3, 5, and 7 mm. Results: 78 patients with POAG classified according to visual field deterioration using Hodapp-Anderson-Parrish grading scale into mild glaucoma 33 eyes, moderate glaucoma 19 eyes, severe glaucoma 26 eyes, and 52 eyes control were included in the study. The mean age of the patients with POAG was 57.82 ± 7.78 years; 22 eyes (50%) were male and 22 eyes (50%) were female. The average age of control subjects was 56.62 ± 8.48 years; 12 eyes (46.2%) were male and 14 eyes (53.8%) were female, average CCT was 530.3 ± 23.58 µm, average mean anterior keratometry (MAK) was 42.97 ± 1.42 D, average maximum anterior elevation (MAE) in 3,5 and 7mm zone was 5.31 ± 2.28, 12.10 ± 6.94 and 44.04 ± 21.99 µm respectively and average maximum posterior elevation (MPE) in 3,5 and 7mm zone was 8.46 ± 2.10, 19.90 ± 9.39 and 62.72 ± 28.82 µm respectively in patients with POAG, whereas average CCT was 543.0 ± 31.02µm, average MAK was 43.11 ± 1.73 D, average MAE in 3,5 and 7mm zone was 4.52 ± 1.97, 5.90 ± 2.71 and 27.19 ± 8.55 µm respectively. Conclusion: Evaluation of corneal elevation topography by scheimpflug imaging showed forward shifting of the anterior and posterior corneal surfaces in POAG.
