Correlation between average retinal nerve fiber layer thickness and rim area of the spectral-domain OCT with the Humphrey visual field index in eyes with glaucoma

@#<p style="text-align: justify;"><strong>OBJECTIVE:</strong> To determine the correlation between the average retinal nerve fiber layer (RNFL) thickness and optic nerve head rim area (RA) measured with a spectral-domain optical coherence tomography (OCT) with the visual field index (VFI) using the Humphrey Visual Field Analyzer in glaucoma patients.<br /><strong>METHODS:</strong> Eighty-five consecutive patients diagnosed with glaucoma underwent spectral-domain OCT of the optic disc and Humphrey perimetry. A glaucoma specialist confirmed the presence of glaucomatous optic neuropathy based on findings in the optic nerve head photographs, OCT measurements of the RNFL and optic disc, and standard automated perimetry. The correlation of the average RNFL thickness and rim area with the VFI was determined using the Spearman's correlation coefficient analysis.<br /><strong>RESULTS:</strong> A total of 121 glaucomatous eyes of 85 patients were included in the study. There were 47 males and 38 females, ages ranging from 12 to 94 years. The average RNFL thickness, RA, and VFI were 67.9 ± 12.3 ?m, 0.65 ± 0.3 mm2, and 56 ± 32%, respectively. The average RNFL thickness (r = 0.35) showed a stronger positive correlation with VFI than RA (r = 0.15), but the difference was not statistically significant.<br /><strong>CONCLUSION:</strong> The average RNFL thickness and rim area of the spectral-domain OCT demonstrated a positive correlation with the VFI of the Humphrey Visual Field Analyzer. The OCT parameters, exemplified by average RNFL and RA, were not good indicators for VFI.</p>

Patient-related barriers to morphine therapy among adult Filipino cancer patients

General Objectives: To determine the biopsychosocial factors among adult Filipino cancer patients the affect their non-compliance to morphine therapy. Specific Objectives: 1) To determine the patient beliefs and misconceptions regarding morphine. 2) To determine the patients' perceived side effects of morphine. 3) To determine the patients' views regarding the accessibility of morphine. 4) To determine the patients' views regarding addiction and fear of tolerance in relation to morphine intake. 5) To determine the patients' concepts on pain relief. 6) To develop a questionnaire that can be used in assessing the patients' attitudes toward morphine treatment.
