Back in 1990, an Israeli team found that breathing through the right nostril (the left was packed with cotton), for 20 minutes decreased IOP an average of 27% in the right eyes and 22.5% in the left in 46 patients with open and closed angle glaucoma, bringing the pressure to normal range.
Prof Dr Yaseen Durrani, a senior ophthalmologist, told Dawn that there are two kinds of glaucoma: open angle and closed angle. Most eye drops available in the market are for one of the two kinds of glaucoma, he said, but pilocarpine drops are effective for both.
Measurement of ACD is of particular value in categorization of glaucoma into open angle and closed angle glaucoma.
The sulcus angle (SA) is the closed angle defined by the intersection of the lines parallel to the articular cartilage of the medial and lateral femoral facets.
For small hyperopic eyes this can lead to acute closed angle glaucoma (CAG) attacks, but in fact 50% of patients have CAG present for years with limited symptoms such as brow pain at twilight.
Clinically, we observed that some patients who were diagnosed with typical PSS with a wide, open angle and suffered from recurrent attacks also had a narrow or closed angle due to aging.
Regarding secondary causes for glaucoma such as uveitis, IOP raise usually complicates the clinical course of these inflammatory processes, creating good premises to compromise the trabecular drainage either with open or closed angle. Closed angle results through pupillary block (posterior synechiae) or forward rotation of the cilliary body without pupillary block [2].
