Object No definitive method of preventing visual field deficits after stereotactic radiosurgery for lesions near the optic radiation (OR) has been available so far. The authors report the results of integrating OR tractography based on diffusion tensor (DT) magnetic resonance imaging into simulated treatment planning for Gamma Knife surgery (GKS). Methods Data from imaging studies performed in 10 patients who underwent GKS for treatment of arteriovenous malformations (AVMs) located adjacent to the OR were used for the simulated treatment planning. Diffusion tensor images performed without the patient's head being secured by a stereotactic frame were used for DT tractography, and the OR was visualized by means of software developed by the authors. Data from stereotactic 3D imaging studies performed after frame fixation were coregistered with the data from DT tractography. The combined images were transferred to a GKS treatment-planning workstation. Delivered doses and distances between the treated lesions and the OR were analyzed and correlated with posttreatment neurological changes. Results In patients presenting with migraine with visual aura or occipital lobe epilepsy, the OR was located within 11 mm from AVMs. In a patient who developed new quadrantanopia after GKS, the OR had received 32 Gy. A maximum dose to the OR of less than 12 Gy did not cause new visual field deficits. A maximum dose to the OR of 8 Gy or more was significantly related to neurological change (p < 0.05), including visual field deficits and development or improvement of migraine. Conclusions Integration of OR tractography into GKS represents a promising tool for preventing GKS-induced visual disturbances and headaches. Single-session irradiation at a dose of 8 Gy or more was associated with neurological change.

The Relationship

The primary aim was to determine if somatosensory impairments alter the association between falls history and glaucoma severity. A secondary aim was to identify the activities of daily living that cause increased concern related to falling in glaucoma and their association with glaucoma severity. Established questionnaires about falls and fear of falling (FoF) were mailed to participants diagnosed with glaucoma. Ninety-eight participants responded. Self-reported feet numbness and tingling symptoms were used to determine the presence of somatosensory impairments. Self-reported falls in glaucoma are associated with visual field deficits in both eyes, particularly in the presence of somatosensory impairments. In addition, increased FoF levels are linked with worse visual field deficits in both eyes, especially when performing challenging walking tasks. Somatosensory impairments alter the relationship between falls risk and visual field deficits in glaucoma. This information may be helpful in identifying older workers at an increased risk of falling.

Visual Field Deficits

23 children who were attending a summer camp for children with learning disabilities and who demonstrated a reading disability at least one grade level below that expected on the basis of chronological age were selected for study. Peripheral visual-field limits were tested for both nasal and temporal fields in both eyes. Testing also took place for central visual field deficits. With very few exceptions the visual field limits were in the range of the accepted norm. 10 randomly selected Ss were retested and the results proved to be reliable as there were no significant differences on first and second testing. It was suggested that an additional study is required which should include a group of children with no reading disabilities.

The Right

In this report, we describe a particular condition of a 52-year-old man who showed advanced bilateral glaucomatous-like optic disc damage, even though the intraocular pressure resulted normal during all examinations performed. Visual field test, steady-state pattern electroretinogram, retinal nerve fiber layer and retinal tomographic evaluations were performed to evaluate the optic disc damage. Over a 4-year observational period, his visual acuity decreased to 12/20 in the right eye and counting fingers in the left eye. Visual fields were severely compromised, and intraocular pressure values were not superior to 14 mm Hg during routine examinations. An accurate anamnesis and the suspicion of this disease represent a crucial aspect to establish the correct diagnosis. In fact, our patient strongly rubbed his eyes for more than 10 h per day. Recurrent and continuous eye rubbing can induce progressive optic neuropathy, causing severe visual field damage similar to the pathology of advanced glaucoma.
