Iris coloboma is a cleft caused by defects in the closure of embryonic fissure, typically, it affects the tissue in the inferonasal quadrant of the eye. We report a case of a 15 years old patient with a typical aspect of “keyhole pupil” which corresponds to inferonasal deficit of the iris tissue.

The Aloha Cabled Observatory (ACO) is located on the seafloor about 100 km north of O‘ahu at 4800 m depth. Seismoacoustic T-waves generated by earthquakes in the South Pacific from Tonga-Kermadec to the Solomon Islands travel 40-70°Δ, passing through an acoustic keyhole—the Ka'ie'ie Waho channel—between O‘ahu and Kaua‘i before reaching ACO. In contrast

Neuroradiology
Keyhole aqueduct syndrome is a rare progressive neurodegenerative disorder describing a unique set of neuro-ophthalmologic, neuroimaging, and histopathological findings on autopsy. A midline mesencephalic cleft communicating with the cerebral aqueduct resembling syrinx is seen on imaging and histopathology. There are 9 cases published in the literature.

Diseases of the Colon & Rectum, 1985
The purpose of this paper is to show whether there is a keyhole deformity, its surgical significance, and how often it occurred following surgery for ulcer-in-ano. To do this, a retrospective study, over a 16-year period, of all patients admitted to the Ferguson Clinic with chief complaints of anal incontinence was undertaken. Of this group of patients,

The Supraorbital Keyhole Approach
Journal of Craniofacial Surgery, 2015Aim: The major aim of the present anatomical study was to demonstrate the anatomical structures that can be visualized using the supraorbital keyhole approach, both endoscopically and microscopically, from an eyebrow incision to intracranial structures. Furthermore, it defines an optimal craniotomy for surgery.

Keyhole cochlear implantation surgery
Cochlear Implants International, 2009A limited access 'keyhole' cochlear implantation (CI) surgical technique is presented. The surgery employs a 15-18 mm diameter C-incision on the rear of the auricle. The implant is retained in a snug pericranial pocket. A bony retention well is avoided. Minimal mastoid cell clearance is used.

Keyhole Deformity: A Case Series
Journal of Gastrointestinal Surgery, 2008Keyhole deformity is frequently encountered after posterior internal sphincterotomy but may be observed after lateral internal sphincterotomy or in patients without any history of previous anal surgery. The aim of the present study is to emphasize the surgical significance of this entity and discuss the possible strategies in the treatment of the ...

Keyhole and multi-keyhole MIMO channels: Modeling and simulation
2011 8th International Conference on Information, Communications & Signal Processing, 2011A simple and effective simulation model for keyhole multiple-input multiple-output (MIMO) channels is introduced. The keyhole is modeled as a pair of transmitting and receiving antennas relaying multipath signals from the transmitter region to the receiver region.
