Background/aim: To evaluate the clinical outcomes of penetrating canaloplasty in traumatic angle recession glaucoma at 1 year.

Methods: Patients with angle recession glaucoma underwent penetrating canaloplasty, a new Schlemm's canal-based internal drainage procedure, which creates a direct canal for flow of aqueous humour from the anterior chamber to the ostia of Schlemm's canal via a window created at the corneal scleral bed without use of antimetabolites. Postoperative intraocular pressure (IOP), number of glaucoma medications, and procedure-related complications were evaluated. Read More

Department of Ophthalmology, Glaucoma Institute of Belo Horizonte, Brazil.

Purpose: To report a successful ab-interno trabeculotomy with Kahook Dual Blade (KDB) in secondary traumatic angle recession glaucoma in a child and discuss the possible mechanisms of action.

Observations: A 7 years-old boy presented, after a blunt trauma in the left eye, with angular recess surroundings 110° and concomitant intra-ocular pressure (IOP) elevation around 35 mmHg, despite the maximum topical and systemic ocular hypotensive therapy. As there was no glaucomatous neuropathy yet, a KDB ab-interno trabeculotomy was performed. Read More

Choroidal rupture is a posterior segment affliction following a traumatic event that results in a break in the retinal pigment epithelium, Bruch membrane, and the underlying choriocapillaris. The visual prognosis may be extremely poor when involving the macular area or in cases with major comorbidities. On funduscopic examination the rupture appears as a whitish/yellowish curvilinear or crescent-shaped lesion with forked or tapered endings. Read More

J Curr Glaucoma Pract 2020 Jan-Apr;14(1):25-29

Department of Statistics, National Institute of Nutrition, Hyderabad, Telangana, India.

Synopsis: Angle recession, trabecular meshwork injury, increased trabecular pigmentation, and reduced Schlemm's canal dimensions can cause reduced aqueous outflow and unilateral glaucoma in an eye, following blunt trauma. Also, these patients are possibly at a risk to develop raised intraocular pressure (IOP) in the normal fellow eye due to reduced Schlemm's canal area.

Aim: To identify and quantitatively evaluate Schlemm's canal (SC) parameters by anterior segment optical coherence tomography (AS-OCT) in the patients with unilateral 360° angle recession glaucoma (ARG) and compare with the fellow normal eyes and age-related normal control. Read More

Department of Ophthalmology, National University Hospital, National University Health System, Singapore.

Purpose: The aim of this study was to report the use of micropulse trans-scleral cyclophotocoagulation as an adjunct therapy for two cases of medically uncontrolled intraocular pressure spikes due to anterior segment inflammation. Case 1 had previous cataract surgery and exhibited an intraocular pressure spike due to phacoantigenic uveitis (right eye intraocular pressure = 52 mmHg). Despite medical treatment, the right eye intraocular pressure remained high (43 mmHg), thus micropulse trans-scleral cyclophotocoagulation was carried out as a rescue therapy. Read More

Ocular trauma is a significant cause of blindness worldwide, particularly if associated with glaucoma. Direct damage from blunt or penetrating trauma, bleeding, inflammation, lens-related problems, orbital and brain vascular pathologies related to trauma, and chemical injuries may increase intraocular pressure and lead to traumatic glaucoma. Treatment may be as simple as eliminating the underlying cause in some conditions or management can be challenging, depending on the mechanism of damage. Read More

Purpose: To study intraocular pressure (IOP) outcomes after surgery for rhegmatogenous retinal detachment in Schwartz syndrome.

Methods: We reviewed records of 32 eyes of 32 patients with Schwartz syndrome (patients with rhegmatogenous retinal detachment, IOP above 21 mmHg, and open angles without angle recession, chronic steroid use or other secondary causes of increased IOP) who had undergone surgical treatment consisting of scleral buckling or vitrectomy. Intraocular pressure, number of medication, best-corrected visual acuity were compared at baseline and postsurgery visits and also studied association of various factors on long-term IOP. Read More

During blunt ocular trauma, the anteroposterior compressive forces confronted lead to consequent equatorial expansion of the globe. This may result in ciliary body trauma, typically manifesting as angle recession or cyclodialysis. The authors hypothesize that a likely asymmetric contraction between the longitudinal and circular ciliary fibers, and an intrinsic weak "oblique buffer zone" creates a plane of separation between the 2, resulting in angle recession.

The purpose of the present study was to assess the ocular surface health status in primary open angle glaucoma (POAG) patients switching from topical application of preserved latanoprost (LT) to preservative-free tafluprost (PFT) by tear proteomic monitoring. Tear fluid of POAG patients showing dry eye symptoms, using LT and switching to PFT as well as tear fluid of healthy controls has been examined. Tear proteome dynamics was monitored over 24 weeks in a first mass spectrometric explorative analysis in a small POAG patient cohort ( = 3). Read More
