Conjunctival biopsies from 11 patients with atopic keratoconjunctivitis (AKC) and from 13 age-matched healthy individuals undergoing cataract surgery were analyzed by light microscopy and immunohistochemical techniques. Histology of AKC specimens showed goblet cell proliferation, epithelial pseudotubular formation, eosinophil and mast cell invasion of the epithelium, and pronounced mononuclear cell infiltration of the substantia propria, often with frank granuloma formation. Epithelium of AKC conjunctiva showed significantly more T cells (CD3+, CD5+), T-helper cells (CD4+), macrophages (Mac-1+, CD14+), activated T cells, (CD25+), and dendritic cells (CD1+), and a higher helper/suppressor ratio than did control subjects. In the substantia propria, AKC specimens showed dramatically increased inflammatory cell infiltration with significantly more cells staining, in order of frequency, for T-cells (CD3+, CD5+), T-helper cells (CD4+), T-suppressor/cytotoxic cells (CD8+), macrophages (CD14+, Mac-1+) activated T cells (CD25+), B cells (CD22+), and dendritic cells (CD1+, HLA-DR+). Fifty-three percent of T cells in the substantia propria expressed the interleukin-2 receptor protein (CD25+). These findings indicate that the chronic conjunctivitis of AKC is complex, with activated T-cells and macrophages dramatically participating in the process. Successful long-term control of the potentially binding conjunctival inflammation of this disease is likely to require therapeutic strategies directed toward more than just the mast cell component of the process.

This survey comparing the primary causes of eye disease and visual impairment between rural and urban areas was conducted from the beginning of February through May of 1989. The outcome of that research on 686 residents (1372 eyes) of Buan-Kun, Chunbuk, and 997 residents (1994 eyes) of Dobong-Ku, Seoul, is as follows: 1. Of the basic ocular affections, pterygium was the most prevalent in Baun-Kun with 178 eyes (13.0%), while allergic and chronic conjunctivitis were in the majority in Dobong-Ku with 170 eyes (8.5%). 2. In causes of visual impairment, refractive error showed to be the main one in both Buan-Kun with 135 eyes (9.8%) and Dobong-Ku with 132 eyes (6.6%). 3. In rate of blindness, Buan-Kun had 7.0% monocular blindness and 3.2% of binocular blindness, while 4.1% of monocular blindness and 1.7% of binocular blindness were found in Dobong-Ku. 4. In causes of blindness, cataract (51.1%) was followed by macular degeneration (17.4%), corneal opacity (13.0%), and vascular retinopathy (9.8%) in Buan-Kun, while cataract (56.0%), macular degeneration (6.7%), corneal opacity (6.7%), and phthisis (6.7%) were recorded in that order in Dobong-Ku.

Recessive epidermolysis bullosa dystrophica (REBD), a bullous disorder of the skin and mucous membranes, is frequently associated with ocular complications. A 40-year-old woman presented with lid ulcerations, chronic conjunctivitis, diffuse subepithelial corneal scarring, corneal ulceration, and cataracts. Management with intensive lubricant therapy, soft-bandage contact lenses, and cataract extraction successfully restored her sight. Histologic examination via light and electron microscopy revealed blister formation and scarring beneath the epithelial basement membrane of both the skin and cornea, confirming the diagnosis of REBD. The ultrastructure of the skin and cornea and the ocular complications of the major forms of epidermolysis are described herein. To our knowledge, successful ocular management of a confirmed case of REBD with complete ocular histopathologic features has not been documented.

Aeromonas hydrophila was isolated from the eye swabs of four patients. Two were thought to have definite clinical infection; one had chronic conjunctivitis complicating the wearing of contact lenses, and the other had acute conjunctivitis associated with ectropion and lacrimal duct stenosis. Two patients had no clinical evidence of infection. Both of them had swabs taken at the time of surgery. One had a cataract extraction and the other had a lensectomy and vitrectomy for a penetrating injury. The outcome was satisfactory in the two patients in whom colonization occurred, and in the patient with acute conjunctivitis, all of whom received chloramphenicol with or without gentamicin. The fourth patient was not followed up.
