The major complication reported is pupillary block (7.7%), which can be prevented and managed with the use of cycloplegics, prophylactic laser iridotomy, oral and topical antiglaucoma drugs, or a partial fill of AC with air or gas.
Group 2 included patients with high intraocular pressure (over 21 mmHg), narrow ACA detected by gonioscopy, glaucomatous optic nerve head changes (notching of optic disc rim, higher vertical cup-to-disc ratio, retinal nerve fiber layer hemorrhages), glaucomatous visual field defects (scotomas indicating loss of the nerve fiber layer), and no history of laser peripheral iridotomy. Inclusion criteria for group 3 were normal intraocular pressure (under 21 mmHg) and no abnormal findings in anterior segment, fundus, or visual field examinations.
It is commonly used to clear the visual axis by disruption of posterior capsule following cataract surgery or iridotomy in narrow angle glaucoma and to cut vitreous bands14.
In another study, an oral combination of forskolin and rutin reduced the rise in intraocular pressure that occurs after laser iridotomy, a procedure used in the treatment and prevention of closed angle glaucoma.
Iridotomy is not effective as the pathogenic mechanism is not pupillary block [3, 5].
Peripheral iridotomy was performed at the 6 o'clock position to prevent a postoperative pupillary block.
Another clinical study showed that oral treatment with an association of forskolin and rutin can blunt the IOP spikes and avoid the damage that may occur after Nd:YAG laser iridotomy for the prevention of primary closed-angle glaucoma [241].
Eight eyes exhibited iatrogenic bullous keratopathy; five had undergone prior argon laser iridotomy (ALI) and three prior cataract surgery and intraocular lens implantation.
The pigment may come from pigment deposition after laser peripheral iridotomy or intraocular surgery, pigment dispersion syndrome, or pigment associated with corneal guttatae.
Iridolenticular contact decreases following laser iridotomy for pigment dispersion syndrome.
