TL;DR: Patients who had other types of visual field loss or loss of visual acuity were more likely to have these signs resolve than were patients with constricted or spiral fields, and treatment did not substantially alter the course.
Abstract: • Forty-two patients with diagnosed functional visual loss were reexamined an average of four years after their initial visit. Twenty-three patients continued to have constricted or spiral visual fields at follow-up. Despite persistent evidence of functional visual defects, few patients were either socially or economically impaired by them. Patients who had other types of visual field loss or loss of visual acuity were more likely to have these signs resolve than were patients with constricted or spiral fields. Concurrent unrelated organic ocular disease was present in 11 patients. In 20 patients, it was not possible to identify psychiatric symptoms either related to the onset of functional eye signs or at follow-up. Treatment did not substantially alter the course.

TL;DR: A review of the literature describing patients with functional visual loss reveals that a significant proportion of them do not manifest psychiatric disease as defined by current nomenclature, and apparently these individuals are highly suggestible and do not necessarily have psychological pathology.

TL;DR: In this paper, the authors reported that despite continued signs of functional visual loss, few were socially or economically impaired, and 8 of these 23 patients had no evidence of any psychiatric disorder at follow-up.
Abstract: Forty-two patients with functional visual loss were followed for more than 4 years after presentation. Only 22 patients had a diagnosable psychiatric syndrome or personality disorder at follow-up. Twenty-three patients continued to have findings of functional visual loss at follow-up. Despite continued signs of functional visual loss, few were socially or economically impaired, and 8 of these 23 patients had no evidence of any psychiatric disorder. The implications of these findings are discussed.

TL;DR: The glucose response to a standard insulin tolerance test in the recovered phase depression in patients who had previously been subclassified according to familial and clinical characteristics suggests that it may be a useful tool in differentiating among the heterogeneous depressive disorders.
Abstract: • The glucose response to a standard insulin tolerance test (ITT) has been reported to be blunted in the acute phase of heterogenous depressive disorders and to be normal in the recovered phase. We studied the glucose response to ITT in the recovered phase of depression in patients who had previously been subclassified according to familial and clinical characteristics. All patients with depressive spectrum disease had an adequate glucose response to the ITT, whereas only 40% of patients with familial pure depressive disease and 56% of patients with bipolar illness had an adequate hypoglycemic response. There was also a trend toward a decrease in insulin sensitivity in patients who had been nonsuppressors to dexamethasone when depressed. These findings suggest that the glucose response to ITT may be a useful tool in differentiating among the heterogenous depressive disorders.

TL;DR: Patients with depressive spectrum disease showed a significantly different growth hormone response to insulin-induced hypoglycemia than patients with bipolar disorder, a finding which suggests differences in alpha-adrenergic receptor sensitivity between these groups.
Abstract: Twenty-eight patients (10 bipolar, 13 depressive spectrum disease, and 5 familial pure depressive), recovered from depression for an average of 1 year, underwent a series of basal and provocative endocrine tests. No significant differences were found among depressive subtypes in thyrotropin, cortisol, or growth hormone measurements either before or after provocative testing with the exception of growth hormone response to insulin-induced hypoglycemia. Patients with depressive spectrum disease showed a significantly different growth hormone response to insulin-induced hypoglycemia than patients with bipolar disorder, a finding which suggests differences in alpha-adrenergic receptor sensitivity between these groups.
