Ocular manifestation of giant cell arteritis vs AL-amyloidosis: similar presentations but different approaches.

Light chain (AL) amyloidosis may present with the features of vasculitis, including giant cell arteritis (GCA). Similarities between GCA and AL-amyloidosis can potentially cause confusion in diagnosis, in which case, temporal artery biopsy (TAB) should be performed to make a definitive diagnosis. Herein we report a case of a bilateral anterior ischaemic optic neuropathy (AION), showing evidence of AL-amyloidosis on the temporal artery biopsy.

Recurrent Squamous Cell Carcinoma of the Eyelid Presenting as Trigeminal Neuralgia.

This paper describes two patients with squamous cell carcinoma (SCC) of the periocular and periorbital skin who presented with trigeminal neuralgia. Both patients had previous cutaneous SCC of the scalp treated successfully with surgical resection but later presented with neuro-ophthalmic findings suggesting perineural invasion (PNI) of SCC. PNI of SCC in the periocular skin or orbit can lead to devastating effects if malignant cells seed into the orbit and adjacent cranial nerves as our two patients developed an orbital apex syndrome.

Combined DSEK and Transconjunctival Pars Plana Vitrectomy.

We report here three patients who underwent combined Descemet's stripping with endothelial keratoplasty and transconjunctival pars plana vitrectomy for bullous keratopathy and posterior segment pathology. A surgical technique and case histories are described. Anatomic and visual outcomes of combined Descemet's stripping with endothelial keratoplasty and vitrectomy were excellent.

The safety and efficacy of photorefractive keratectomy after laser in situ keratomileusis.

Purpose: To determine the safety and efficacy of performing photorefractive keratectomy (PRK) in corneas previously treated with laser in situ keratomileusis (LASIK) surgery.

Methods: Fifteen eyes of 14 patients who had initially received LASIK for the treatment of myopia and compound myopic astigmatism were evaluated. Variables included existence of and/or type of flap complication associated with the original LASIK procedure, refractions before and after (3 and 6 months) PRK, uncorrected visual acuity (UCVA), best spectacle-corrected visual acuity (BSCVA), and the development of complications after PRK such as haze, scarring, double vision, or ghosting.

Ketorolac for the regression of myopic LASIK overcorrection.

Objective: To determine whether ketorolac (Acular) treatment and other factors influence regression after LASIK-induced consecutive hyperopia.

Methods: Seventy-two eyes of 51 patients who had undergone LASIK for myopia and compound myopic astigmatism and who experienced consecutive hyperopia of at least +0.50 diopters within the first postoperative week were analyzed.

Retinal evaluation of patients on chronic amiodarone therapy.

Purpose: To determine whether retinal electrophysiologic changes can be detected and correlated with funduscopic findings in patients with the long-term use of amiodarone.

Methods: Eleven patients ranging in age from 52 to 67 years were recruited from the Stanford University Medical Center Department of Cardiology for ophthalmologic examination. Patients had received amiodarone at various dosages ranging from 100 to 800 mg daily for at least 15 months.

Iatrogenic keratoconus as a complication of radial keratotomy.

A 47-year-old man with a family history of keratoconus had uneventful bilateral radial keratotomy (RK) with astigmatic keratotomy (AK) enhancements 12 years earlier. He noticed a gradual onset of blurry vision with progressively increasing myopic shift. Visual acuity remained poor even with spectacles or soft contact lenses.

Laser in situ keratomileusis for myopia and compound myopic astigmatism using the Technolas 217 scanning-spot laser.

Purpose: To evaluate the safety, efficacy, predictability, and visual results of laser in situ keratomileusis (LASIK) using the Bausch & Lomb Technolas(R) 217 scanning-spot laser for the treatment of myopia and compound myopic astigmatism.

Setting: Stanford Eye Laser Center, Stanford, California, USA.

Methods: In a prospective study, 110 eyes of 58 patients with a mean spherical equivalent (SE) of -4.

Progression to end-stage glaucoma after laser in situ keratomileusis.

We describe 2 patients, one a glaucoma suspect because of family history and the other with juvenile glaucoma. Both patients developed complications after laser in situ keratomileusis that required frequent topical steroids, leading to steroid-induced glaucoma. In both cases, corneal edema from the acute rise in intraocular pressure (IOP) caused inaccurate IOP measurement by standard methods.
