“…Similarly, we found lower MMSE scores in the glau coma patients than in the healthy C group. Hagerman et al found that 32% of patients with low vision had cognitive impairment as determined by the MMSE (21) . In contrast, Cumurcu et al showed no significant differences in the MMSE score among pseudoexfoliative glaucoma patients, POAG patients, and healthy controls (22) .…”

RESUMO Objetivos: Avaliar as diferenças de desempenho cognitivo entre pacientes com glau coma primário de ângulo aberto (POAG), glaucoma de pressão normal (NTG) e controle de indivíduos saudáveis (C).Métodos: Um total de 60 pessoas (20 POAG, 20 NTG e 20 85,2 ± 14,7, 76,8 ± 10,3 e 91,4 ± 7,7 µm nos grupos POAG, NTG e controles, respectivamente (p<0,001). As espessuras médias da GCIPL observadas foram 77.5 ± 9.7 μm no grupo POAG, 73,4 ± 7,8 ABSTRACTPurpose: To assess cognitive performance differences among primary open-angle glaucoma (POAG) patients, normal-tension glaucoma (NTG) patients, and healthy control (C) subjects. Methods: A total of 60 participants (20 POAG, 20 NTG, and 20 C subjects) were included in this study. A detailed ophthalmologic examination was performed on all participants. A spectral domain-optical coherence tomography (SD-OCT) system was used to measure the ganglion cell-inner plexiform layer (GC-IPL) and retinal nerve fiber layer (RNFL) thicknesses. To assess the cognitive performance of all participants, detailed neurological examinations, including the mini-mental state examination (MMSE), were performed by the same neurologist. Results: There were no significant differences among the groups in terms of age (p=0.348) or gender (p=0.935). The mean RNFL thicknesses were significantly diffe rent among the groups (85.2 ± 14.7, 76.8 ± 10.3, and 91.4 ± 7.7 µm in the POAG, NTG, and C subjects, respectively; p<0.001). The mean GC-IPL thicknesses were 77.5 ± 9.7 µm in the POAG group, 73.4 ± 7.8 µm in the NTG group, and 78.8 ± 3.8 µm in the C group. Differences among the groups were not statistically significant (p=0.085). MMSE scores were 26.1 ± 1.4, 25.7 ± 2.3, and 28.8 ± 0.9 in the POAG, NTG, and C groups, respectively. There were significant differences among the three groups (p<0.001). Specifically, there were significant differences between the NTG and C groups (p<0.001), and between the POAG and C groups (p=0.001). There was no significant difference between the POAG and NTG groups (p=0.595). Conclusions: There appear to be similar risk factors in glaucoma and neurodegenerative disorders that cause deterioration in cognitive performance. Comparing the low MMSE scores of the POAG and NTG patients with the scores of healthy C participants supports our hypothesis. Consequently, it is recommended that a neurologist should also examine glaucoma patients.

Purpose:To assess cognitive performance differences , if any,among primary open-angle glaucoma (POAG) patients, normal-tension glaucoma (NTG) patients, and healthy control (C) subjects.Methods:60 age and sex matched subjects (20 POAG, 20 NTG, and 20 C subjects) were included in this study. Following routine ophthalmological examination the cognitive performance of all participants, detailed neurological examinations, including the mini-mental state examination (MMSE), were done.Results:The mean RNFL thicknesses were significantly different among the groups in the POAG, NTG, and C subjects, respectively; p <0.001). MMSE scores were 24.1 ± 2.4, 25.2 ± 3.8 and 28.9 ± 0.9 in the POAG, NTG, and Controls groups, respectively. There were significant differences among the three groups (p <0.001). Moreover, there were significant differences between the NTG and Controls groups (p <0.001), and between the POAG and Controls groups (p<0.001).Conclusions:The overlapping pathogenesis in glaucoma and neurodegenerative disorders cause deterioration in cognitive performance. Decreased values of MMSE scores in POAG and NTG patients compared to the scores of healthy controls suggest a detailed neurological examination of glaucoma patients. Keywords: neurodegenerative disease, cognition, dementia, open angle glaucoma

“…Because cognitive ability could impact the ease and speed with which an older adult masters new techniques or devices, cognitive status may be an important component of success in LVR. Although one small previous study indicated that cognitively impaired LVR patients can experience improvement in visual acuity using low vision aides(13), the impact of cognitive status on task-related functional trajectories in LVR patients has not been described.…”

“…Nonetheless, high rates of cognitive deficits among older adults referred to outpatient LVR have been reported (13, 14). The objective of the current study was to determine whether cognitive status is predictive of task-related functional trajectories among older adults receiving LVR.…”

Comorbid cognitive impairment and functional trajectories in low vision rehabilitation for macular disease

Background and Aims Comorbid cognitive impairment is common among visually impaired older adults. This study investigated whether baseline cognitive status predicts functional trajectories among older adults in low vision rehabilitation (LVR) for macular disease. Methods The Telephone Interview for Cognitive Status – modified (TICS-m) was administered to macular disease patients aged ≥ 65 years receiving outpatient LVR. Mixed models assessed the rate of change in instrumental activities of daily living and visual function measures over a mean follow-up of 115 days. Results Of 91 participants, 17 (18.7%) had cognitive impairment (TICS-m score ≤ 27) and 23 (25.3%) had marginal impairment (TICS-m scores 28 to 30). Controlling for age and gender, baseline cognitive status did not predict most functional outcomes. However, participants with marginal cognitive impairment experienced worse functional trajectories in ability to prepare meals (p=0.03).and activities that require distance vision (p = 0.05). Conclusion Patients with mild to moderate cognitive impairment should not be excluded from LVR, but programs should be prepared to detect and accommodate a range of cognitive ability.
