Argon and diode laser treatment of benign eyelid lesions.

This study reports the experience of 14 patients (15 lesions) treated with the argon or diode laser for small, benign eyelid conditions. The technique is suitable for use by ophthalmic surgeons because the lesions are localised, the surgery can be performed precisely to maintain adequate lid function and cosmesis, and both the argon and diode laser viewing systems and delivery systems provide excellent control for the surgery. There were no complications from the laser surgery, and the surgical aims of lesion clearance, good cosmesis and function were fulfilled in all patients. The advantages in lid surgery of the diode and argon lasers over the carbon dioxide laser are highlighted.

The Valsalva DCR bubble test: a new method of assessing lacrimal patency after DCR surgery.

Objective confirmation of nasolacrimal patency following dacryocystorhinostomy is a desirable postoperative goal for both the surgeon and the patient. The authors describe a simple method to demonstrate dacryocystorhinostomy patency and present a study comparing the effectiveness of this novel test with Jones fluorescein testing in 32 cases seen consecutively at postoperative follow-up. The test consists of demonstrating reflux of air through the dacryocystorhinostomy as the patient performs the Valsalva maneuver. This reflux is most easily seen as bubbles rising through a drop of saline placed in the medial canthus. A high correlation was found between this test and Jones testing. The Valsalva dacryocystorhinostomy bubble test (VBT) appears to be a fast, safe, and accurate method of confirming dacryocystorhinostomy patency.

The corneal quilt: a protective device designed to reduce intraoperative retinal phototoxicity.

The corneal quilt is a simple, safe, inexpensive, and effective device designed to decrease the risk of intraoperative retinal phototoxicity from the operating microscope. Retinal injury is a well documented hazard, especially during prolonged procedures. The corneal quilt can be easily used as an adjunct to other methods designed to protect the retina from excessive incident light. In this study, we fashioned an approximately 6- x 5-millimeter semi-transparent corneal occluder from the nonadhesive portion of a 3M Steridrape. We determined spectrophotometrically that the corneal quilt reduced the transmission not only of visible light, but of ultraviolet and blue wavelengths as well, the wavelengths known to be the most phototoxic to the retina. However, no data were obtained actually demonstrating the degree to which light is scattered after transmission through the corneal quilt.

Prospective evaluation of one surgeon's first 100 cases of endocapsular phacoemulsification cataract surgery.

In this series of one surgeon's first 100 cases of endocapsular phacoemulsification cataract surgery (EPECS), believed to be the first truly prospective study of its kind, 86% of patients achieved corrected vision of 6/6 to 6/4; 96% achieved vision of 6/12 or better; and excluding those with pre-existing pathology, 99% achieved 6/12. Posterior capsular rupture occurred in 11 cases, with vitrectomy being required in eight cases. Detailed analysis of the 100 cases is provided.

The Koch endocapsular punch. A report on its use in 96 consecutive cases.

The technique of endocapsular cataract extraction and intraocular lens implantation surgery provides optimal surgical conditions and more reliable intraocular lens positioning in the capsular bag. Several capsulectomy techniques are in use to remove anterior capsule from the central zone. The Koch endocapsular punch provides a new technique for creating a continuous anterior capsulectomy. In this study the Koch punch was used in 96 eyes consecutively undergoing intended endocapsular cataract extraction and intraocular lens implantation. Ninety-five eyes had appropriate lens centration at six months. There were no cases of vitreous loss. Ninety-nine per cent of cases had visual acuity of 6/6 or better at six months. This data demonstrates the Koch endocapsular punch to be an effective and safe means for anterior capsulectomy.

Punctal dyeing: an adjunct to intraoperative lacrimal punctal identification.

During lid operations, identifying the lacrimal punctum is sometimes difficult. The difficulty may be increased following local anesthetic infiltration into the medial canthus and manipulation of the lid tissues. Punctal dyeing with a skin marking pen is a simple technique that improves visualization of the lacrimal punctum during surgery in this region. Preceded by punctal dilatation, it lasts for the duration of standard lid or lacrimal procedures.

Ocular cicatricial pemphigoid.

A series of 17 patients with ocular cicatricial pemphigoid (OCP) is described retrospectively. The importance of early recognition, especially of disease involving the medial canthus and caruncular region, diagnosis by biopsy, and adequate immunosuppressive and surgical therapy, are emphasised. A detailed grading scheme has been developed and this has enabled the authors to determine the success or failure of the therapy during the active treatment period. A combined ophthalmological and immunological approach to treatment can result in a successful visual outcome of this potentially blinding disease.

Ophthalmic manifestations of perineural spread of facial skin malignancy.

Facial skin malignancy, when complicated by perineural spread (PNS), can lead to devastating orbital, intracranial and paranasal sinus involvement, the management of which requires a multidisciplinary approach and which itself may be devastating. Adequate surgical excision with frozen section control, and specific inspection of histological specimens for perineural invasion, are essential to avoid this problem. This report presents four patients who manifested such involvement, and emphasises the importance of recognition of such ominous symptoms as facial pain, paraesthesiae and weakness. Thorough neuro-ophthalmic examination is mandatory to detect signs of nerve involvement which may indicate perineural spread both at the initial assessment of primary tumour and at suspected recurrence. In this series, the most common sensory and motor nerves affected were, respectively, single, small branches of the ophthalmic and facial nerves.
