The Effect of Iridotomy on Iris Contour

American Journal of Ophthalmology, 1990
With a recently developed technique for quantifying the geometry of the anterior chamber in optical cross section (slit-lamp photography using the Scheimpflug principle and computer correction for the optical effects of the cornea), we studied the iris contour before and after iridotomy in six patients with narrow anterior chamber angles and angle ...

Alpha-gal syndrome (AGS) in a glaucoma suspect with narrow iridocorneal angles

American Journal of Ophthalmology Case Reports, 2023
Purpose: Alpha-gal syndrome (AGS) is an allergy to non-primate mammalian carbohydrate (galactose-alpha-1,3-galactose) which may cause anaphylaxis. Allergic patients must avoid ophthalmic drugs containing animal-derived ingredients.

Laser Iridotomy [PDF]

BMJ, 1970
A ruby laser has been used to produce a permeable lesion in the iris to establish a communication between the anterior and posterior chambers. In a preliminary study in nine patients the technique gave satisfactory results in the prophylactic treatment of four cases of incipient closed-angle glaucoma and of two cases of iris bombé following uveitis.

Increase in anterior chamber angle depth after topical pilocarpine measured by spectral domain optical coherence tomography: A possible additional indicator for laser peripheral iridotomy in primary angle-closure suspects in an opportunistic set-up

Indian Journal of Ophthalmology, 2022
Purpose: Indication of laser peripheral iridotomy (LPI) is often conjectural due to dependency on gonioscopy and strict dichotomous classification of occludability.
