Cataract Extraction + Canaloplasty in Setting of Long Anterior Zonules (Malik Y. Kahook, MD)
This is a case of long anterior zonules with pigment dispersion glaucoma and a visually significant cataract. It was decided that the patient required cataract extraction and we decided to perform concomitant STREAMLINE® SURGICAL SYSTEM Canaloplasty to decrease intraocular pressure. In the setting of long anterior zonules, the capsulorhexis should be smaller to avoid the anteriorly positioned zonules which can redirect the leading edge of the rhexis. This video shows the proper technique for both cataract surgery as well as STREAMLINE® canaloplasty.

zhlédnutí 416Před rokem
Long Anterior Zonules (LAZ) are characterized by zonular fibers that extend more central than usual onto the anterior lens capsule (normal insertion is about 1.5-2 mm anterior to equator). LAZ was postulated by Vogt to be remnants of tunica vasculosa lentis due the presence of persistent pupillary membranes in some LAZ eyes. Patients with LAZ should be examined and monitored for glaucoma and re...

Plateau Iris Syndrome is a form of angle closure more common in younger female patients. The pathology is thought to be due to anteriorly positioned ciliary processes pushing the peripheral iris forward leading to angle closure. A double hump sign is seen on indentation gonioscopy. During indentation, the peripheral iris drapes over the anteriorly displaced ciliary processes and creates a sign ...

    The cupping theory was mistakenly introduced into the ophthalmology establishment the 1850s. At the time, ophthalmologists found the optic discs of subjects with painless blind eyes as being ‘cupped’ when seen for the first time with the newly invented ophthalmoscope. However, the cupping theory has been unable to explain the orderly, peripheral-to-central loss of nerve fibers occurring in primary open-angle glaucoma - a salient feature of this disease.

      eyewiki.aao.org/Examination_of_the_Optic_Nerve_at_the_Slit-Lamp_Biomicroscope_with_a_Handheld_Lens The dimensions of the disc should be measured along its long axis making sure to account for the magnification factor of the lens being used - x1.00, x1.08, and x1.32 for the Volk Super 66, 78, and 90 diopter lenses, respectively. Other methods for determining disc size includes using the 5 degree aperture on the direct ophthalmoscope that closely approximates the size of a normal disc. Also, confocal scanning laser ophthalmoscopes can provide detailed measurements during examination. Care should be taken not to include the zones around the disc in the measurement such as the scleral lip or the zones of alpha and beta atrophy (see Step 7).

    Very useful tips. Some doctors here stopped using ECP because of severe inflammation with cyclitic membranes, etc. Do you use or advocate the use of intracameral triamcinolone (neat or diluted) at the end of the procedure?

    • @malikkahook9368
      @malikkahook9368 Před rokem

      Inflammation post ECP is of course expected, but a high degree of inflammation is usually due to over-treatment with popping of the tissue that should be avoided. I find painting the ciliary processes and stopping the treatment before the tissue pops leads to less inflammation. While I don't routinely use steroids, I have in the past used 0.1 ml of 4 mg/ml dexamethasone in the AC at the end of surgery and others do as well. More darkly pigmented eye can experience more inflammation and this might be the right population to use dex in if desired.

    • @malikkahook9368
      @malikkahook9368 Před rokem

      There are a couple of things that can be done depending on how bothersome it is...this ranges from the surgical (closing the holes and making a new one elsewhere) to doing something like a corneal tattoo which blocks light entering the hole. Often times, the symptoms go away on their own after a few months, but a year is a long time and you should discuss options with your surgeon if the symptoms are really bothering you.

      I am in the same situation and appreciate you bringing up the possibility of replacing the hole. My current issue is with holes positioned superiorly, causing significant dysphotopsia with multiple white lines. I plan to wait a year to assess my tolerance. At the moment it has already started to impact my daily routine, particularly when working on the computer. I am thinking about to ask my eye doctors to close my holes and put it to a more favorable position. (3 and 9 temporal, as far much away from my eye lids) I have wide angle glaucoma and the blockage only happened with fully dilated pupil. In normal condition the IOP fluctuates in a normal range. A gonioscope examination revealed that the angles are open, but some parts appear closed. (since i diagnosed with glaucoma and examed with gonioscope mayn times, everybody said it was opened) I am wondering if another viable option could involve closing the hole and using Pilocarpine during the nights. Your insights on this matter would be greatly appreciated.@@malikkahook9368

      Treatments to lower pressure target stabilization rather than improvement of vision. Depending on the subtleties of your situation, it is worth the time to discuss with your treating physician what your visual symptoms are and what can be done to make things better. A rise in eye pressure does not typically alter central vision until the later stages of disease and your vision might be influenced by other processes (like dry eye) that can be treated and lead to vision improvement. Please discuss with your doctor.

Think about the time and effort required to train a senior consultant (from birth to the point that they become an expert) and compare it with the effort needed to train an AI model. The gap will increase knowing that to teach another human expert, we still need decades, but we can transfer knowledge between AI models in seconds.
