“…Because lesions that damage the body of the optic chiasm characteristically produce bitemporal hemianopia [15], bitemporal field changes were the most common field defects on presentation in pituitary adenoma. However, according to tumor size and optic chiasmal position, a variety of field defects from monocular superior temporal defects to bilaterally constricted fields can be produced [6]. In our study, there were 29 patients (74%) with VF defects and bitemporal hemianopsia was also the most common type.…”

“…In addition, there were seven monocular VF defects respecting the vertical meridian and three homonymous hemianopsia. Hershenfeld and Sharpe [16] reported that the cause of 64% of monocular hemianopsia was pituitary adenoma and several authors reported that it can cause homonymous hemianopsia [6,17]. Therefore brain imaging should be considered if patients showed not only binocular but also monocular VF defects respecting the vertical meridian.…”

“…Rivoal et al [6] demonstrated that patients with VF abnormality had larger tumors and only the size of the adenoma was a significant factor for VF defects. Thomas et al [13] demonstrated that the severity of field defects and visual loss were related to tumor size.…”

“…Because of its anatomical relationship with the optic chiasm, pituitary adenoma typically results in bitemporal hemianopia. However, according to tumor size and optic chiasmal position, a variety of field defects can be produced by pituitary adenoma and the tumor size is a significant factor for the severity of VF defects [5,6]. …”

PurposeWe used the Swedish interactive threshold algorithms (SITA) standard strategy of Humphrey perimetry, to analyze the pattern of visual field (VF) defects and evaluate the quantitative correlation between the tumor volume and severity of VF defects in patients with pituitary macroadenoma.MethodsWe reviewed 50 patients with pituitary macroadenoma who received VF test and 11 patients were excluded. VF analysis was performed with Humphrey perimeter using the SITA standard strategy. The tumor volume was assessed radiologically via brain magnetic resonance images and was calculated using Cavalieri's principle. We used the mean deviation (MD) and pattern standard deviation (PSD) of the Humphrey parameter to measure VF defect severity, and then analyzed the correlation of tumor volume with VF defects.ResultsTwenty nine patients (74%) showed abnormal VF and bitemporal field changes, which were the most common field defects on presentation. Seven patients (18%) had unilateral VF defects, 22 patients (56%) had bilateral VF defects. The tumor volume of the patients with VF defects was significantly larger than that of patients with normal VF (p = 0.006). The tumor volume exhibited significant negative correlation with MD (r = -0.693; p < 0.001) and significant positive correlation with PSD (r = 0.589; p < 0.001).ConclusionsIn patients with pituitary macroadenoma, there was a variety of VF defects and a high correlation between the tumor volume and the severity of VF defects. SITA standard strategy can be a fast and quantitative method for evaluating central VF defects.

“…Some studies have identified improvement as long as 5 years following surgical resection. [52] Poor prognostic signs for improvement of visual fields include dense and extensive preoperative visual field deficit,[52] pituitary tumor volume greater than 5 cc[53] and the postoperative development of a surgically “empty sella”[54] (which is associated with inflammatory scarring and descent of the chiasm into the empty sella).…”

Visual field assessment is important in the evaluation of lesions involving the visual pathways and should be performed at baseline and periodically in the follow-up. Standard automated perimetry has been shown to be adequate in neuro-ophthalmic practise and is now the technique of choice for a majority of practitioners. Goldman kinetic visual fields are useful for patients with severe visual and neurologic deficits and patients with peripheral visual field defects. Visual fields are useful in monitoring progression or recurrence of disease and guide treatment for conditions such as idiopathic intracranial hypertension (IIH), optic neuropathy from multiple sclerosis, pituitary adenomas, and other sellar lesions. They are used as screening tools for toxic optic neuropathy from medications such as ethambutol and vigabatrin. Visual field defects can adversely affect activities of daily living such as personal hygiene, reading, and driving and should be taken into consideration when planning rehabilitation strategies. Visual field testing must be performed in all patients with lesions of the visual pathway.
