Wednesday, November 23, 2016: It is at this point in our day's activities that we introduce the project's ophthalmologist/musician (or is it the other way round? I can never remember), Dr. Suman ji. Our research participants meet Dr. Suman ji for their first time during the non-mydriatic slit-lamp examination. Here, Dr. Suman ji (1) checks for any diseases of/injury to the eye lids and corneas, (2) assesses the pupillary reflex (a marker for possible neurological disease), (3) looks for any changes in the iris such as atrophy, (4) measures intraocular pressure (IOP), a known risk factor for primary open angle glaucoma, using Goldmann Applanation Tonometry, and (5) performs gonioscopy to assess the angle of the anterior chamber. For individuals with glaucoma the angle of the anterior chamber helps distinguish those with open angle or angle closure glaucoma. Furthermore, for individuals with a narrow anterior chamber angle it is imperative that mydriatic drops are not administered as an acute attack of angle closure glaucoma may be brought on due to the periphery of the contracted iris (the iris contracts due to a dilated pupil) blocking the normal flow of aqueous humour through the trabecular meshwork.
