Clinical case with iCare COMPASS perimeter

In January 2017 a 63 years old male was referred for suspected normal tension glaucoma in the right eye. The treatment was Ganfort ou.

• The anterior segment of both eyes is normal
• Retinal nevus in the right eye
• Excavated optic nerve head ou
• Stop glaucoma medication, patient stayed stable

OCT looks normal but the traditional visual field shows “nasal step”. One year later an iCare COMPASS test is performed:

• Nevus with exudation looking like a nasal step defect. The exudate leads to retinal detachment and a detachment causes loss of sensitivity;
• Myelinization of the ganglion axons: congenital anomaly on the temporal retina which causes a reduction of sensitivity because myelinization blocks light from passing through.

Thanks to the iCare COMPASS perimeter, the areas of depressed sensitivity, nevus and atrophic retina are clearly seen. After a COMPASS exam it was decided to stop treatment with IOP lowering medications. Patient was stable in the last follow-up.
