Management of acute corneal hydrops with intracameral gas injection.

Purpose: To report two cases of severe acute corneal hydrops that were resolved by intracameral gas injection alone.

Observations: Case 1 is a 27-year-old woman with bilateral severe keratoconus who developed sequential acute corneal hydrops in the right eye followed by the left eye that were each successfully treated using intracameral 20% sulfur hexafluoride gas injection. Case 2 is a 62-year-old man that developed a large fluid cleft beneath a pre-existing LASIK flap, which resolved with intracameral 20% sulfur hexafluoride gas injection without the need for corneal transplantation.

Unusual presentation of presumed posterior polymorphous dystrophy associated with iris heterochromia, band keratopathy, and keratoconus.

Purpose: To report an unusual presentation of posterior polymorphous corneal dystrophy (PPCD) associated with band keratopathy, iridocorneal adhesions, heterochromia, keratoconus, and confocal microscopic findings suggestive of iridocorneal endothelial syndrome.

Methods: Confocal microscopy, corneal topography, electroretinography, and genetic analysis were performed in the proband and his siblings.

Results: A 23-year-old man presented with decreased vision in both eyes over 9 months.

Non-syndromic supernumerary caruncles causing ocular irritation after cataract surgery: a critical review of caruncular dysgeneses.

Purpose: To describe a patient with 2 ipsilateral supernumerary caruncles and to determine if they are predictive of associated abnormalities.

Design: Retrospective and interventional clinicopathologic study with a critical review of the literature over the past 100 years.

Methods: Assessment of clinical features and histopathologic findings in paraffin-embedded tissue sections stained with hematoxylin and eosin, Masson trichrome, periodic acid-Schiff (PAS) reaction with and without diastase, and Ziehl-Neelsen method.

Tear cytokine profiles in dysfunctional tear syndrome.

Purpose: To compare tear cytokine and chemokine concentrations in asymptomatic control and Dysfunctional Tear syndrome (DTS) patients and determine the correlations between tear inflammatory mediators and clinical severity.

Design: Prospective observational cohort study.

Methods: Concentrations of epidermal growth factor (EGF), interleukin (IL)-1 alpha (1alpha), 1 beta (1beta), 6, 10, 12, and 13, interferon gamma (IFN-gamma), tumor necrosis factor alpha (TNF-alpha), and chemokines: IL-8 (CXC); macrophage inflammatory protein-1 alpha (MIP-1alpha) (CCL3); and regulated upon activation, normal T-cell expressed and secreted (RANTES CCL5) were measured by a multiplex immunobead assay in an asymptomatic control group and DTS patients with and without meibomian gland disease (MGD).

Change in astigmatism after temporal clear corneal cataract extraction in the pediatric population.

Purpose: To evaluate the early postoperative change in astigmatism in pediatric patients having cataract extraction with intraocular lens implantation using sutured temporal clear corneal incision.

Methods: A retrospective chart review was performed on all pediatric patients who underwent clear corneal cataract surgery with intraocular lens implantation between 12/01/2005 and 11/30/2006.

Results: A total of 31 eyes of 22 patients who underwent temporal clear corneal cataract surgery and intraocular lens implantation were included.

Family members' preferences for nutrition interventions to improve nursing home residents' oral food and fluid intake.

Objectives: To measure family members' preferences for nutrition interventions to improve the oral food and fluid intake of their relatives in a nursing home.

Design: Cross-sectional descriptive.

Setting: Three skilled nursing facilities in Southern California.
