Keratitis associated with multiple endocrine deficiency.

PURPOSE: To report an 8-year-old girl with bilateral progressive visual loss and photophobia secondary to stem cell deficiency as a result of multiple endocrine deficiency. METHODS: A case report and review of medical literature. RESULTS: The patient suffered from severe photophobia and decreased visual acuity since May 2000. Despite multiple outpatient visits, no definite cause was found, and conservative treatments failed. On slit-lamp examination severe meibomian gland dysfunction, loss of eyelashes, decreased tear meniscus, diffuse corneal vascularization, and delayed punctate fluorescein staining of corneal epithelium were detected. She had also episodes of hypotension, oral candidiasis, and seizures. Her systemic work up revealed multiple endocrine deficiency (Addison disease and hypoparathyroidism). Hormone replacement therapy with fludrocortisone and oral calcium accompanied by punctual occlusion led to significant clinical recovery. CONCLUSION: In a pediatric patient with diffuse corneal vascularization and no definite cause, systemic workup should be done to rule out multiple endocrine deficiencies. Treatment consists of hormone replacement therapy and management of the dry eye.

Outcomes of phacoemulsification and in-the-bag intraocular lens implantation in Fuchs' heterochromic iridocyclitis.

PURPOSE: To evaluate the visual outcomes and complications of phacoemulsification (PE) and posterior chamber intraocular lens implantation, (PC IOL) in patients with Fuchs heterochromic iridocyclitis (FHIC). SETTING: Private clinic and an academic hospital. METHODS: In this noncomparative interventional case series, existing data for 41 eyes of 40 consecutive patients clinically diagnosed with FHIC and cataract were studied retrospectively. Scleral tunnel PE and in-the-bag IOL implantation were performed in all cases. Preoperative and postoperative visual acuities and intraoperative and postoperative complications were evaluated. RESULTS: Twenty-four male and 16 female patients aged 12 years to 70 (SD) (mean 35 +/- 12 years) were operated on and followed for 17.8 +/- 8.7 months. Preoperatively, best corrected visual acuity (BCVA) was less than 20/40 in all patients, which improved to 20/40 or better after surgery. Twenty-two eyes (53.6%) achieved BCVA of 20/20. The major cause of postoperative visual acuity less than 20/20 was vitreous haze. There were no major intraoperative complications. Postoperatively, mild anterior chamber fibrin reaction occurred in 4 patients (9.7%), IOL deposits occurred in 11 eyes (26.8%), and decentration was observed in 1 eye. During follow-up, 6 eyes (14.6%) developed posterior capsule opacification requiring a neodymium:YAG (Nd:YAG) laser capsulotomy. There was 1 case of clinical cystoid macular edema that resolved with medication. There were no cases of posterior synechias, postoperative glaucoma, or retinal detachment. CONCLUSION: Phacoemulsification with PC IOL implantation is a safe procedure with good visual outcomes in patients with FHIC and cataract.

Chronic and delayed-onset mustard gas keratitis: report of 48 patients and review of literature.

PURPOSE: To report the clinical features of 93 eyes of 48 patients with chronic and delayed-onset mustard gas keratitis. Clinicopathologic correlation in 5 eyes and a review of related literature are presented. DESIGN: Retrospective, noncomparative case series. PARTICIPANTS: Forty-eight Iranian survivors of Iraqi chemical warfare with chronic or delayed-onset mustard gas keratitis. METHODS: We reviewed the symptoms, clinical findings, course, and treatment of our patients and reviewed the literature. In 5 patients, histopathologic features of corneal and conjunctival specimens were evaluated. MAIN OUTCOME MEASURES: Ocular findings, clinical course, treatment measures, and histopathologic studies. RESULTS: Of 48 patients, 31 (64.6%) had chronic symptomatology, whereas 17 (35.4%) experienced delayed-onset lesions. Visual acuity at referral ranged from hand motions to 20/20. Ocular surface changes included chronic blepharitis and decreased tear meniscus in all patients, limbal ischemia (81.3%), and conjunctival vascular abnormalities (50%). Corneal signs in order of frequency were: scar or opacity (87.5%), neovascularization (70.8%), thinning (58.3%), lipoid deposits (52.1%), amyloid deposits (43.8%), and epithelial defects and irregularity (31.3%). Many patients received conservative treatment; others underwent allograft stem cell transplantation (20 eyes of 17 patients), penetrating keratoplasty (12 eyes of 12 patients), and lamellar keratoplasty (4 eyes of 3 patients). Conjunctival specimens were evaluated by light microscopy. Decreased goblet cell density, attenuated or thickened epithelium, scarring in the substantia propria associated with plasmacytic and lymphocytic infiltration, and dilated lymphatic vessels were noted. Excised corneal buttons disclosed absence of epithelium and Bowman's layer, fibrovascular pannus, stromal scarring, and vascularization. CONCLUSIONS: Mustard gas causes chronic and delayed destructive lesions in the ocular surface and cornea, leading to progressive visual deterioration and ocular irritation. The pathophysiologic features of these changes are not clearly identified. Excised conjunctival and corneal specimens revealed a mixed inflammatory response without any specific features. Based on the clinical appearance of the lesions and the histopathologic findings, an immune-mediated component seems possible. This article contains additional online-only material available at.

Concomitant keratoconus and macular corneal dystrophy.

OBJECTIVE: To report the concomitant presentation of keratoconus and macular corneal dystrophy in two cases. METHODS: Two siblings with concomitant keratoconus and macular corneal dystrophy are presented. Complete ophthalmologic examination and computerized videokeratography were performed in both patients. Case 1 underwent penetrating keratoplasty in both eyes sequentially; histopathologic examination of excised corneal buttons with special stains was performed. Case 2 was observed. RESULTS: Both patients manifested typical signs and topographic evidence of keratoconus associated with macular dystrophy. Histopathologic studies in case 1 confirmed the same clinical diagnosis. CONCLUSION: To our knowledge, this is the first report of such a concurrence in the English literature and could lead to further studies on the possible pathophysiologic or genetic link between these 2 entities.
