“…Second, the diagnosis of Charles Bonnet Syndrome is made across different disciplines including optometry, ophthalmology, geriatric medicine, psychiatry, and neurology. Third, many people are hesitant to report that they experience visual hallucinations for fear of being labeled as mentally unstable 1,7–9. As the geriatric population increases, the amount of acquired vision loss will also increase.…”

“…These patients will usually have some cognitive impairment due to the disease. According to Chen and colleagues, a woman with multiple sclerosis lost vision from optic neuritis and began experiencing complex and vivid visual hallucinations 9. In another case, a woman with multiple sclerosis noticed that her visual hallucinations disappeared once she regained vision 23.…”

“…Hallucinations in the form of Charles Bonnet syndrome (Formal, complex, persistent, stereotypical visual hallucinations) were described in a 56-year-old woman with multiple sclerosis, but without any cognitive impairment or any comorbid psychiatric symptoms. 37 Visual field defects particularly homonymous hemianopia, are common following stroke including our own data. Vision recovers in the hemianopic field in stages starting with perception of light and followed by motion, form, colour and stereognosis in that order.…”

Visual loss is a common presenting symptom in the Outpatient Departments of Neurology, Ophthalmology and General Medicine disciplines. The present prospective study aims at evaluating 48 patients with partial or total visual loss as the predominant or only presenting symptom and with no associated ocular problems like cataract, glaucoma or diabetic retinopathy. The neurological causes were identified, analysed and tabulated; 39% of patients were below 20 years of age and there was 3:2 ratio of female versus male prevalence. Nearly 66% had acute visual loss and 35% had chronic visual loss. Majority of patients (48%) had profound visual loss limited to finger counting; 6% had normal visual acuity associated with field defects. The visual evoked potentials were abnormal in all cases with acute and sub-acute presentation and in some patients with sudden or chronic presentation also. The VEP abnormalities consisted of prolonged P100 latencies, loss of amplitudes or poor wave morphology. Cranial CT scan was done in 36 patients and was abnormal in 83% patients. It showed intracranial tumours in 8% patients and infarcts in another 8% patients. Cranial MRI scan was done in 12 patients and was normal in 83% patients. The aetiological considerations and treatment protocols followed are discussed. The limitations of such study in the present setup are also highlighted.

“…While CBS is typically described in chronic visual disturbances, cases have been reported in acquired visual defects following neurosurgical procedures, 6,7 occipital lobe infarction, 8 enucleation, 9,10 temporal arteritis, 11,12 central nervous system tumors with and without optic nerve involvement, [13][14][15] acute anemia, 16 and multiple sclerosis. [17][18][19][20] In cases of acute visual deficits, CBS symptoms may develop immediately or with a latency of several days to months. 2 Symptoms most commonly occur on awakening and may display a consistent pattern in terms of frequency, timing, and duration.…”

An 87-year-old patient presented with a 6-week history of an isolated progressive destructive nodular eyelid mass, secondary nodular and ulcerative lesions, and regional painful lymphadenopathy. After 4 weeks, fungal cultures demonstrated Sporothrix schenckii. S. schenckii is a rare dimorphic fungus that can occasionally involve the periocular skin. The authors' case demonstrates typical clinical features, emphasizes the delay in diagnosis, and shows effective treatment with oral itraconazole.
