Which angle closure eyes benefit from lens removal/cataract surgery? | Augusto Azuara-Blanco[06:22]
This video describes current evidence regarding the role of lens extraction in patients with angle closure. In brief, patients with co-existing angle closure and cataract will benefit from early lens extraction. For those patients with clear lens and significant angle closure disease there is evidence that phacoemulsification is more effective than peripheral laser iridotomy. Combining … Continue reading
How do I treat a bleb-related inflammation? | Vijaya Lingam[06:05]
Bleb associated infection (BAI), found most commonly in thin cystic blebs, is a vision threatening complication after Trabeculectomy. There are three stages of BAI: stage I – blebitis with inflammation confined to bleb, stage II – blebitis with associated anterior chamber reaction but no vitritis, and stage III – blebitis complicated with vitritis. In order … Continue reading
How can I tell if an OCT is reliable? | Donald Hood[05:21]
There are four reasons given as to why the OCT may not accurately reflect a particular patient’s level of damage. Each is only partially true. First, it is believed that arcuate-like artifacts on OCT maps from healthy eyes can be confused with arcuate defects due to glaucoma. In fact, arcuate-like artifacts can be distinguished from … Continue reading
Is glaucoma an asymptomatic disease, or are there visual symptoms? | Pradeep Ramulu[05:36]
While there are many methods too ascertain the severity of glaucoma with various forms of testing (clinical exam, visual fields, OCT imaging), direct patient communication can also help understand the extent to which a patient with suspected or known glaucoma is affected by their disease. In this video and its summary, we discuss at what … Continue reading
Surgical management of nanophthalmos with angle-closure glaucoma | Sharmila Rajendrababu[10:21]
Nanophthalmos is a rare disease with crowded anterior segment and increased scleral thickness. Surgery in Nanophthalmos is often prone for Vision threating complications like Uveal effusions and retinal detachment. Careful pre-operative planning and intraoperative Prophylactic Selerostomy may minimize the risk of complications. This presentation is meant to provide an overview and practical tips for safe … Continue reading
Classification of Angle Closure | Tin Aung[04:49]
Primary angle closure occurs when there is an anatomical obstruction of the aqueous humor outflow by the iris without a secondary pathological cause. We can identify several stages of the disease defined by the presence of certain structural and functional characteristics that define each stage. The stages have been termed as follows: Primary Angle Closure … Continue reading
How do I perform a non-penetrating glaucoma surgery? | Alain Bron[09:44]
In this presentation, you will find all the details on how to perform deep sclerectomy, one of the procedures for non-penetrating glaucoma surgery. This surgery is designed for open angle glaucomas and offers a much safer profile than trabeculectomy. However, the IOP-lowering effect is a bit less than trabeculectomy. The procedure does not require any … Continue reading
How do I teach a patient about how to put in eye drops? | Kessara Pathanapitoon[04:13]
One of the factors that is negatively correlated with adherence to topical glaucoma therapies is difficulty in applying drops. Only a small number of patients can correctly administer exactly one drop without touching the eye. Patients with more years of experience or given better education were likely to instill a single drop and have the … Continue reading
How should I treat glaucoma in pregnant and lactating patients? | Yvonne Buys[05:34]
There are multiple challenges and uncertainties related to the management of glaucoma management in women planning a pregnancy, during pregnancy, and during the breastfeeding period.

Tips for intraoperative gonioscopy and how to perform goniosynechiolysis | Kazuhiko Mori[08:46]
Increasingly, glaucoma specialists require expertise in surgical gonioscopy, as lots of MIGS procedures with ab interno approaches utilize a surgical goniolens. Goniosynechialysis (GSL), which physically separates peripheral anterior synechiae from trabecular meshwork, also utilizes surgical goniolens. There are two types of surgical goniolens; direct type and double mirror type. Direct gonioprisms which have been widely … Continue reading
What visual field testing strategy should I use? (SITA Standard/Fast/Faster 30-2/24-2/24-2C) | Anders Heijl[05:56]
This video will discuss choosing SITA tests for glaucoma management. Original SITA Standard and SITA Fast strategies represented a change of paradigms: time-saving, very computer-intensive with maximum likelihood estimations in real time. SITA Faster is a further development of SITA Fast. Definitively detecting perimetric progression and measuring rate of progression usually requireat least 5 tests. … Continue reading
How is Suturolysis best performed? | Eytan Blumenthal[07:15]
Suturelysis (SL) is a powerful and relatively simple procedure enabling the opening of scleral flap (sub-Tenon) sutures utilizing an Argon-like (green) laser. It increases flow across the trabeculectomy fistula thus lowering intraocular pressure. During trabeculectomy, a scleral flap is created, which, if left unsutured, would flatten the anterior chamber and collapse the eye. Well-placed sutures … Continue reading
What is the best way to examine the optic nerve for early detection of glaucoma? | Remo Susanna[06:18]
The optic nerve examination is the most important component of the evaluation of a glaucoma patient. The appearance of the optic nerve can assist with diagnosing glaucoma and detecting its progression. It is irreplaceable in detecting nonglaucomatous causes of ONH cupping and visual field defects similar to those in glaucoma. A systematic process of disc … Continue reading
