Probability model of the inaccuracy of residual stromal thickness prediction to reduce the risk of ectasia after LASIK part II: quantifying population risk

PURPOSE: To derive a statistical model to estimate the rate of excessive keratectomy depth below a selected cut-off residual stromal thickness (RST) given a minimum target RST and specific Clinical Protocol; apply the model to estimate the RST below which ectasia appears likely to occur and back-calculate the safe minimum target RST that should be used given a specific Clinical Protocol. METHODS: Myopia and corneal thickness distribution were modeled for a population of 5212 eyes that underwent LASIK. The probability distribution of predicted target RST error (Part I) was used to calculate the rate of excessive keratectomy depth for this series. All treatments were performed using the same Clinical Protocol; one surgeon, Moria LSK-One microkeratome, NIDEK EC-5000 excimer laser, Orbscan pachymetry, and a minimum target RST of 250 microm--the Vancouver Clinical Protocol. The model estimated the RST below which ectasia appears likely to occur and back-calculated the safe minimum target RST. These values were recalculated for a series of microkeratomes using published flap thickness statistics as well as for the Clinical Protocol of one of the authors-the London Clinical Protocol. RESULTS: In the series of 5212 eyes, 6 (0.12%) cases of ectasia occurred. The model predicted an RST of 191 microm for ectasia to occur and that a minimum target RST of 329 microm would have reduced the -rate of ectasia to 1: 1,000,000 for the Vancouver Clinical Protocol. The model predicted that the choice of microkeratome varied the rate of ectasia between 0.01 and 11,623 eyes per million and the safe minimum target RST between 220 and 361 microm. The model predicted the rate of ectasia would have been 0.000003: 1,000,000 had the London Clinical Protocol been used for the Vancouver case series. CONCLUSIONS: There appears to be no universally safe minimum target RST to assess suitability for LASIK largely due to the disparity in accuracy and reproducibility of microkeratome flap thickness. This model may be used as a tool to evaluate the risk of ectasia due to excessive keratectomy depth and help determine the minimum target RST given a particular Clinical Protocol.

Atopic optic neuritis

PURPOSE: To report a case of optic neuritis associated with atopic dermatitis, which may represent an optic nerve counterpart of atopic myelitis. METHODS: Clinical examination, MRI, blood investigations. RESULTS: A 34-year-old man with severe atopic dermatitis developed a steroid-responsive bilateral optic neuritis. Serum IgE was highly elevated, with high titers of mite-specific IgE. Clinical ophthalmological fluctuations paralleled those of atopic dermatitis. CONCLUSIONS: The clinical features and parallel fluctuations strongly suggest that the patient's optic neuritis was related to atopic dermatitis. This atopic optic neuritis may represent the optic nerve equivalent of atopic myelitis.

Ethambutol neuroretinopathy

OBJECTIVE: To describe the clinical features of ethambutol neuroretinopathy. DESIGN: Case report and meta-analysis of the literature. PARTICIPANTS: A patient with clinical and electrophysiological findings suggestive of ethambutol neuroretinopathy. TESTING: Electroretinogram, electro-oculogram and visual fields. MAIN OUTCOME MEASURE: Clinical and electrophysiological findings. RESULTS: 101 cases were reviewed, retinal findings include retinal pigment epithelial changes, macular edema, flame-shaped hemorrhages. Electroretinogram findings include decreased amplitude and abnormal wave pattern in full field ERG, multifocal or pattern ERG and electro-oculogram findings include abnormal Arden ratio. CONCLUSIONS: Clinical, electrophysiological and in vitro studies support the toxic effect of ethambutol on the retina. Therefore ethambutol ocular toxicity may be a neuroretinopathy.     

Giant cell arteritis with spontaneous remission

BACKGROUND: Clinical manifestations of giant cell arteritis (GCA) are variable. Whether signs and symptoms present in an explosive fashion or insidiously, once manifest the course is usually progressive unless treatment is initiated. METHODS: A retrospective review of patients with GCA seen in an outpatient neuro-ophthalmology clinic. RESULTS: We report four patients with biopsy-proven GCA who experienced spontaneous remission. Clinical manifestations consisted of headache and diplopia in two patients, constitutional symptoms in one patient and facial pain in another. CONCLUSIONS: Clinicians should be aware of this aspect of the disease in order to avoid a delay in diagnosis and treatment.
