Chemical injury can occur if cleaning solutions such as povidone-iodine (Betadine), chlorhexidine or alcohol are inadvertently spilt into the eye, for example when the face, neck or shoulder is being prepped for surgery. [4] [1] Therefore, the anaesthetist ensures that the eyes are fully closed and remain closed throughout the procedure.
The Hughes procedure is an oculoplastic procedure which is performed to reconstruct a lower eyelid defect. It is usually performed as a 2-stage procedure. [1] [2] The most common use for the Hughes procedure is reconstruction after the removal of a lower eyelid skin cancer. [3] The result aims to recreate the normal appearance and function of ...
Donor site 8 days after a skin graft. Skin grafting is a surgical procedure where a piece of healthy skin, also known as the donor site, is taken from one body part and transplanted to another, often to cover damaged or missing skin. [12] Before surgery, the location of the donor site would be determined, and patients would undergo anesthesia. [13]
Incision lines for blepharoplasty. The thorough pre-operative medical and surgical histories, and the physical examination of the patient's periorbital area (eyebrow-to-cheek-to-nose), determine if the patient can safely undergo a blepharoplasty procedure to feasibly resolve (correct or modify, or both) the functional and aesthetic indications presented by the patient.
The pupil is a hole through which the eye's interior can be viewed. For better viewing, the pupil can be opened wider (dilated; mydriasis) before ophthalmoscopy using medicated eye drops (dilated fundus examination). However, undilated examination is more convenient (albeit not as comprehensive), and is the most common type in primary care.
Dilated fundus examination (DFE) is a diagnostic procedure that uses mydriatic eye drops to dilate or enlarge the pupil in order to obtain a better view of the fundus of the eye. [1] Once the pupil is dilated, examiners use ophthalmoscopy to view the eye's interior, which makes it easier to assess the retina , optic nerve head , blood vessels ...
Normal fundus photographs of the left eye (left image) and right eye (right image), seen from front so that left in each image is to the person's right. Each fundus has no sign of disease or pathology. The gaze is into the camera, so in each picture the macula is in the center of the image, and the optic disk is located towards the nose. Both ...
Ocular surgery may be performed under topical, local or general anesthesia. Local anaesthesia is more preferred because it is economical, easy to perform and the risk involved is less. Local anaesthesia has a rapid onset of action and provides a dilated pupil with low intraocular pressure.
