PURPOSE To describe a pilot study that evaluates the efficacy and mechanism of action of a new glaucoma operation, trabeculectomy with internal tube shunt. METHODS Twenty-three patients underwent the new operation in one eye for open angle glaucoma. Under a scleral flap, a deep sclerectomy was performed, resulting in an intrascleral lake. Laterally, on both sides, a small silicone tube was pl...

An eight‐year‐old girl presented with a one‐week history of redness in the right eye. Best corrected visual acuity was 6/6 bilaterally. The right eye showed mild circumcorneal congestion and a worm in the central cornea [Figure 1], which showed a wiggling motility under high magnification of slit lamp. The rest of the ocular examination was normal. Considering the very central location of the w...

BACKGROUND We have developed a new surgical instrument, called the pulsed electron avalanche knife (PEAK; Carl Zeiss Meditec, Jena, Germany), for precise, "cold," and tractionless dissection of tissue in liquid media. OBJECTIVE To evaluate the 3-dimensional damage zone induced by the PEAK compared with 2 other standard intraocular surgical instruments, diathermy and retinal scissors. METHOD...

An argon laser iridectomy was performed on 18 eyes of 14 patients with closed-angle glaucoma. The intraocular pressure (IOP) was controlled in all but one eye within normal limits. Variable amounts of pigment were found on gonioscopy in all cases. The mydriasis test was positive in one eye (5.5%) after homatropine and in 5 eyes (28%) after tropicamide drops. 80% of the positive results occurred...

O cular hypotony is associated with significant visual dysfunction depending on its severity and duration. One etiology of hypotony is cyclodialysis cleft (CDC), a disinsertion of the longitudinal ciliary muscle fibers from the scleral spur. Originally described as a planned surgical treatment for intractable glaucoma, CDC may be observed following trauma or as an inadvertent surgical event fro...

UNLABELLED The study shows a promising next-generation surgical option for the correction of moderate to high ametropia. Hole implantable collamer lens (ICL), STAAR Surgical, is a posterior chamber phakic intraocular lens with a central artificial hole. As yet, however, no long-term comparison of the clinical results of the implantation of ICLs with and without such a hole has hitherto been con...

as the stage next to that of corneal section and iridectomy in the extraction of a hard cataract; and I believe that this rule is invariably followed by the ophthalmic surgeons of the present day. The modification I propose, and have adopted in all my late cases, is to tear the capsule of the lens as the first preliminary step in the operation for extraction of cataract. The advantages accruing...
