Abstract

BACKGROUND AND OBJECTIVE: To evaluate the outcome of repeated excimer laser keratectomy after photorefractive keratectomy (PRK). PATIENTS AND METHODS: A retrospective study of 32 of 1000 consecutive patients who had a follow-up of at least 12 months and who underwent repeated PRK in the Assutah Laser Center. RESULTS: The mean spherical equivalent (SE) declined significantly as a result of the repeated treatment. As opposed to zero eyes before re-treatment, 19 of 29 eyes (66%) achieved SE of within +/-1 D 6 months after re-treatment. Before re-treatment, 20 of 32 eyes (62%) had medium or severe haze, whereas after re-treatment only 1 of 29 eyes (3%) had medium haze, and none of the eyes had severe haze. At 6 months after reoperation, visual acuity had improved to 20/36, a significant improvement to the mean log MAR equivalent of 20/40 before re-treatment, yet still significantly worse than the log MAR equivalent before initial ablation which was 20/30. CONCLUSION: Repeated excimer laser PRK has the potential for successful treatment of undercorrection, regression, and haze occurring after an initial PRK.

Multifocal lamellar keratitis following laser in situ keratomileusis.

Over a period of approximately 7 months, multiple subepithelial spots were noted in one or both corneas of some patients examined 2 to 6 months after laser in situ keratomileusis (LASIK). The lesions appeared identical to adenovirus keratitis. The eyes were quiet, had good vision, and no patient had a history of adenoviral keratoconjunctivitis. In all eyes, the lesions resolved spontaneously or with topical steroid eyedrops. All investigations were negative for adenovirus. Corneal laser scanning in vivo confocal microscopy revealed Langerhans cells in the epithelium, which disappeared after the lesions resolved.

Hypergammaglobulinemia and corneal opacities in patients with human T-cell lymphotrophic virus type-1.

PURPOSE: To investigate the relationship between serum immunoglobulin levels and corneal opacities in a cohort of patients with human T-cell lymphotrophic virus type-1 (HTLV-1). DESIGN: Retrospective case series. METHODS: Complete ophthalmologic examination was performed on 44 patients with HTLV-1 infection (25 patients with adult T-cell leukemia/lymphoma [ATL], 18 patients with HTLV-1 that was associated myelopathy/tropical spastic paraparesis [HAM/TSP], and one patient who was asymptomatic). Corneal opacities were described by shape, size, color, and location. Serum immunoglobulin (Ig) levels (IgG, IgM, and IgA) were measured by nephelometry. RESULTS: Corneal opacities were identified in 15 of 25 patients (60%) with ATL and five of 18 patients (28%) with HAM/TSP. The prevalence of corneal opacities was associated statistically with elevated IgG level (P = .023) in patients with ATL, but not in patients with HAM/TSP (P > .99). CONCLUSION: Although the mechanism remains unclear, hypergammaglobulinemia is associated with the development of the corneal opacities in patients of African descent with ATL.
