We report 2 cases of Cogan syndrome that developed after uneventful laser in situ keratomileusis. In the first case, an 8-month postoperative biomicroscopy revealed bilateral interface neovascularization, white intrastromal deposits, and anterior chamber cells and flare. In the second case, white cell infiltration and neovascularization were observed in the deep corneal stroma of the patient's right eye 18 months postoperatively.

ST2 gene products that are members of IL-1 receptor family are expressed in various cells such as growth-stimulated fibroblasts and Th2 helper T-cells, and recently, IL-33, which belongs to IL-1 family, was identified as the ligand for ST2L, the receptor type product of the ST2 gene. Subsequently, IL-33 and ST2L have been reported to be involved in Th2 immunity and inflammation, however, their functions on non-immunological cells are still obscure. Among non-immunological adhesive cells, vascular endothelial cells were reported to express both ST2 gene products and IL-33, therefore, we investigated the expression manner of the ST2 gene in vascular endothelial cells and the effect of IL-33 on endothelial cells.

Purpose: To review corneal wound healing with special reference to the function of the Bowman layer and Descemet membrane.

Methods: Corneal specimens were obtained from keratoplasties, including regrafted cases. Recipient corneal buttons were evaluated histopathologically with attention to 5 layers of corneal structure: 3 cellular layers consisting of epithelial cells, keratocytes, and endothelial cells and 2 acellular layers consisting of the Bowman layer and Descemet membrane.

Purpose: Diagnosis of Salzmann's nodular degeneration is based on clinical findings, as histopathologic findings in nodules are nonspecific on routine examination. This study demonstrates that presence of oxytalan fibers (ie, elastic system fibers) in lesions of Salzmann's nodular degeneration under light and electron microscopy allows definitive diagnosis.

Methods: A 55-year-old woman noticed white nodular lesions on both corneas.

Purpose: The gene expression profile of human corneal endothelium (CE) was established with the gene signature system. A novel gene, GS3582, was abundantly transcribed in the CE compared with other tissues according to a human gene expression database. This protein was designated corneal endothelium-specific protein (CESP)-1.

Purpose: To describe a technique for the prevention of spontaneous loss of lacrimal punctal plugs.

Design: Interventional case series.

Methods: Four consecutive patients (10 puncta in seven eyes) with severe dry eyes who experienced repeated spontaneous plug loss underwent punctal occlusion by suturing plugs with 10-0 polypropylene sutures.

Objective: To characterize diurnal intraocular pressure (IOP) changes in primary open-angle glaucoma by reproducing IOPs based on patient posture.

Methods: In 148 patients with untreated primary open-angle glaucoma who had IOPs recorded during clinic hours that were less than 21 mm Hg (average, 14.8 +/- 3.

Purpose: To examine the incidence of benign and malignant eyelid lesions and conjunctival tumors.

Subjects And Methods: One-hundred-and twenty-eight cases (131 eyes) which were treated during the period from January 1990 to February 2004 were histopathologically diagnosed for eyelid or conjunctival tumors (87 cases of eyelid tumors and 41 cases of conjunctival tumors) in retrospective evaluations. The incidence of benign or malignant lesions, the pathological classification, age, sex, and clinical diagnostic accuracy were all investigated.

Purpose: We report the first case of subconjunctival mucosa-associated lymphoid tissue (MALT) lymphoma arising in Tenon's capsule (fascia bulbi).

Methods: A 75-year-old woman presented with painless swelling of the superior bulbar conjunctiva in her left eye. During the biopsy of the bulbar lymphoid lesion, it was noticed that the conjunctiva was movable and that the lesion was located in the subconjunctiva.

Purpose: To confirm the predictive value of the results of a 4-week trial of latanoprost alone, timolol-gel alone, or a combination of the two in normal-tension glaucoma (NTG) patients, when compared with the hypotensive response after a 6-month trial using the same combination of eye drops for the same patients.

Methods: One eye each of 45 NTG patients was used in a prospective 4-week trial of latanoprost alone, timolol-gel alone, or a combination of the two. Patients continued using the eye drops for 6 months, according to the results of the trial.

Purpose: To determine damaged DNA-binding protein 2-gene expression levels in vitro and ex vivo, and the degree of DNA repair in damaged DNA-binding protein 2-overexpressing cultured human corneal endothelium after ultraviolet irradiation.

Methods: Constitutive damaged DNA-binding protein 2-gene expression levels in various human tissues were determined by semi-quantitative reverse transcription-polymerase chain reactions. The dynamics of nucleotide excision repair-related gene expression in cultured human corneal endothelium were investigated in a ribonuclease protection assay after ultraviolet-irradiation.

Damaged DNA-binding protein (DDB) is a heterodimer (DDB1 and DDB2), which is implicated in the repair of UV-irradiated DNA damage. Here we have identified four DDB2 variants from HeLa cells (D1-D4) that are generated by alternative splicing. Analysis of tissue distribution by RT-PCR indicates that D1 is the most highly expressed in human brain and heart.

Purpose: To further evaluate the role of draining cervical lymph nodes (CLN) in high-risk (HR) corneal allografts performed in vascularized beds. Recently, we have shown that CLN are critical for promotion of allograft rejection in normal-risk corneal allografts.

Methods: Fully mismatched HR orthotopic corneal transplantation was performed in BALB/c hosts that had their CLN excised before transplantation (CLN-).

Background: Immune deviation induced by an injection of antigens (Ags) in the anterior chamber of the eye has been termed anterior chamber-associated immune deviation (ACAID). Inoculated Ag induces the generation of T cells that down-regulate delayed-type hypersensitivity (DTH). The induction mechanism may well involve various cytokines.
