Patient Care

As the name suggests these are diagnostic procedures where the results obtained from the tests should be correlated with the clinical findings. Various references from other Hospitals are also studied here.

Electro-Retinogram (ERG) - objective testing done for retinal function

Electro-Oculogram (EOG) - objective testing done for RPE (retinal pigment epithelium) function

Visual Evoked Potential (VEP) - objective measurement of the visual stimulation which is monitored by visual status

Patients who have congenital defects in retinal components like rods, cones etc. are usually referred. However for VEP, malingering cases and cases in which the visual pathway is affected (e.g. Lesions in the visual pathway) are referred. Based on the results obtained on the tests individually or, in some cases, with two tests the results are analyzed and are correlated with the clinical presentation of the patient. Based on these findings the Optometrist diagnoses the case.
