A 68 Age - year Age - old Age man Sex was referred Clinical_event by his Subject optometrist Subject to HES Nonbiological_location with suspected LTG Disease_disorder due to repeatedly Detailed_description irregular Detailed_description visual Diagnostic_procedure field Diagnostic_procedure test Diagnostic_procedure results Diagnostic_procedure , advanced Detailed_description optic Diagnostic_procedure disc Diagnostic_procedure cupping Diagnostic_procedure , normal Lab_value intraocular Diagnostic_procedure pressures Diagnostic_procedure ( IOPs Diagnostic_procedure ) and a family history of glaucoma Disease_disorder .
The patient subjectively felt that vision Sign_symptom in his ‘ good Detailed_description ’ left Biological_structure eye Biological_structure ( LE Biological_structure ), which normally had a visual Diagnostic_procedure acuity Diagnostic_procedure of 6/6 Lab_value N5 Lab_value , started to deteriorate Detailed_description 6 Date   months Date earlier Date ; at the point of referral it Coreference was best corrected to 6/7.5 Lab_value N6 Lab_value .
His right Biological_structure eye Biological_structure ( RE Biological_structure ) was known to be amblyopic Disease_disorder with a visual Diagnostic_procedure acuity Diagnostic_procedure of 6/18 Lab_value N12 Lab_value .
His medical history included considerable risk History factors History for systemic Detailed_description vasculopathy Disease_disorder , such as hypertension Disease_disorder , hypercholesterolaemia Disease_disorder , 50 Lab_value pack Lab_value - years Lab_value of smoking History and type Disease_disorder 2 Disease_disorder diabetes Disease_disorder with no diabetic Disease_disorder retinopathy Disease_disorder .
Despite detailed questioning, he denied any new Sign_symptom systemic Sign_symptom symptoms Sign_symptom apart from experiencing increased Lab_value lethargy Sign_symptom .
Clinical Diagnostic_procedure examination Diagnostic_procedure at HES Nonbiological_location revealed advanced Detailed_description bilateral Detailed_description cupped Diagnostic_procedure optic Diagnostic_procedure discs Diagnostic_procedure with a cup Diagnostic_procedure - to Diagnostic_procedure - disc Diagnostic_procedure ratio Diagnostic_procedure right Detailed_description 0.9 Lab_value ( 90% Lab_value ) and left Detailed_description 0.8 Lab_value ( 80% Lab_value ; figure 1).
Furthermore, the findings Diagnostic_procedure from the referring Detailed_description optometrist Subject of equal Diagnostic_procedure and Diagnostic_procedure reactive Diagnostic_procedure pupils Diagnostic_procedure , normal History eye Diagnostic_procedure movements Diagnostic_procedure and IOPs Diagnostic_procedure in mid Age - teens Age were confirmed.
Computerised Diagnostic_procedure perimetry Diagnostic_procedure showed constricted Detailed_description visual Diagnostic_procedure fields Diagnostic_procedure in both Lab_value eyes Biological_structure , albeit with considerably Lab_value raised Lab_value false Diagnostic_procedure - negative Diagnostic_procedure error Diagnostic_procedure rates Diagnostic_procedure in Lab_value excess Lab_value of Lab_value 30% Lab_value (figure 2A).
Since this Coreference can be a result of poor Severity concentration Sign_symptom and attention Sign_symptom span Sign_symptom with Detailed_description testing Detailed_description compounded Detailed_description , especially with an amblyopic Disease_disorder RE Biological_structure , the field Diagnostic_procedure test Diagnostic_procedure was repeated 4 Date   weeks Date later Date with Detailed_description similar Detailed_description results Detailed_description (figure 2B).
At this visit Clinical_event , the patient experienced further Lab_value deterioration Lab_value of his ‘ good Detailed_description ’ LE Biological_structure .
Visual Diagnostic_procedure acuities Diagnostic_procedure measured 6/24 Lab_value ( loss Detailed_description of Detailed_description one Detailed_description Snellen Detailed_description line Detailed_description ) N36 Lab_value in his amblyopic Disease_disorder RE Biological_structure , and 6/18 Lab_value ( loss Detailed_description of Detailed_description two Detailed_description Snellen Detailed_description lines Detailed_description ) N36 Lab_value in his LE Biological_structure , which now also showed depressed Lab_value colour Diagnostic_procedure vision Diagnostic_procedure .
An urgent Detailed_description scan Diagnostic_procedure of the patient's head Biological_structure and orbit Biological_structure was requested to rule out a compressive Detailed_description lesion Disease_disorder and blood Diagnostic_procedure analysis Diagnostic_procedure was carried out to screen for other Diagnostic_procedure causes Diagnostic_procedure of Diagnostic_procedure optic Diagnostic_procedure neuropathy Diagnostic_procedure including vitamin Diagnostic_procedure B12 Diagnostic_procedure , folate Diagnostic_procedure levels Diagnostic_procedure and inflammatory Diagnostic_procedure markers Diagnostic_procedure .
MRI Diagnostic_procedure revealed a large Biological_attribute mass Disease_disorder centred at the pituitary Biological_structure fossa Biological_structure measuring approximately 4.5 Volume   cm×5.1 Volume   cm× Volume 4.8 Volume   cm Volume (figure 3A–C) extending into the suprasellar Biological_structure cistern Biological_structure and infrasellar Biological_structure sphenoid Biological_structure sinuses Biological_structure .
The optic Biological_structure chiasm Biological_structure and both Lab_value optic Biological_structure nerves Biological_structure were displaced Detailed_description superiorly Detailed_description and compressed Detailed_description on Detailed_description both Detailed_description sides Detailed_description .
The mass Disease_disorder showed heterogeneous Detailed_description T1 Diagnostic_procedure and T2 Diagnostic_procedure signals Diagnostic_procedure with multiple Lab_value fluid Diagnostic_procedure levels Diagnostic_procedure most likely due to previous haemorrhage Disease_disorder and low Diagnostic_procedure - signal Diagnostic_procedure components Diagnostic_procedure suggesting calcifications Disease_disorder .
The Coreference appearance Coreference was probably due to a craniopharyngioma Disease_disorder or haemorrhagic Detailed_description pituitary Disease_disorder adenoma Disease_disorder .
The patient was referred Clinical_event urgently to the neurosurgery Nonbiological_location unit Nonbiological_location and was found to have markedly Lab_value raised Lab_value prolactin Diagnostic_procedure levels Diagnostic_procedure of greater Lab_value than Lab_value 200 Lab_value   000 Lab_value   mIU/L Lab_value , confirming the diagnosis of a giant Severity prolactinoma Disease_disorder .
In cooperation with the local Nonbiological_location endocrinology Nonbiological_location service Nonbiological_location , he was started on cabergoline Medication 500 Dosage   µg Dosage and dexamethasone Medication 8 Dosage   mg Dosage .
Within Date a Date week Date this led to a dramatic Lab_value improvement Lab_value of the patient's visual Diagnostic_procedure fields Diagnostic_procedure and Diagnostic_procedure acuities Diagnostic_procedure to 6/18 Lab_value RE Biological_structure and to 6/9 Lab_value LE Biological_structure .
His prolactin Diagnostic_procedure levels Diagnostic_procedure showed a similar dramatic Lab_value response Lab_value with Lab_value levels Lab_value coming Lab_value down Lab_value to 336 Lab_value  mIU/L.
Three Date months Date later Date his visual Diagnostic_procedure acuity Diagnostic_procedure in his RE Biological_structure and LE Biological_structure were 6/18 Lab_value and 6/5 Lab_value , respectively, and visual Diagnostic_procedure field Diagnostic_procedure examination Diagnostic_procedure showed striking Detailed_description recovery Detailed_description with almost Detailed_description normal Detailed_description results Detailed_description (figure 2C).
