ABSTRACT
Ligneous conjunctivitis (LC) is a rare form of pseudomembranous conjunctivitis seen in children, perhaps due to plasminogen deficiency, which manifest as a chronic refractory pseudomembranous conjunctivitis. LC cases are incapable in maintaining their fibrinolytic activity due to plasminogen deficiency; consequently, transudates of plasma assume as a thick, gelatinous, woody membranes over the mucosal surfaces. This is a short case report on a child with a LC, who presented with recurrent pseudomembranous conjunctivitis in conjunction with progressive congenital hydrocephalus due to aqueductal stenosis (Dandy–Walker syndrome). This rare association was clinically confirmed and prompt corrective surgical measures were instituted.
ABSTRACT
Macular corneal dystrophy is autosomal recessive dystrophy characterized by deposits of abnormal glycosaminoglycans in stromal lamellae and within endothelial cells. Deep anterior lamellar keratoplasty is successful in the management of this dystrophy. We herein describe three cases of primary graft failure after uneventful big bubble deep anterior lamellar keratoplasty for macular corneal dystrophy.
ABSTRACT
A 33-year-old male underwent an optical keratoplasty elsewhere in the right eye following which he developed endophthalmitis and subsequently underwent a pars plana vitrectomy and lensectomy. At presentation, he had a deep stromal crystalline infiltration along the graft–host junction. A large therapeutic keratoplasty was performed, and the excised corneal button was evaluated. Histopathology revealed gram-positive round-to-oval budding structures and microbiology identified the organism as Candida glabrata. He was treated with antifungals in the postoperative period. At 4 months after therapeutic keratoplasty, the patient developed recurrent endophthalmitis, following stoppage of antifungals. The treatment was reinstituted for another year, and the patient did well with a clear graft at 18-month-follow-up period after the recurrence episode. Management of infectious crystalline keratopathy with endophthalmitis is a challenging situation and requires long-term treatment.
ABSTRACT
Purpose: The purpose of this study is to evaluate the outcomes of keratoplasty for lattice corneal dystrophy (LCD) performed at a tertiary eye care center. Methods: A retrospective review of medical records of those patients who were clinically diagnosed to have LCD (72 eyes of 57 patients) and underwent either penetrating keratoplasty (PK, 58 eyes of 46 patients) or deep anterior lamellar keratoplasty (DALK, 14 eyes of 13 patients) between the years 1987 and 2014 was performed. The main outcome measures included demographics, clinical features, and outcomes of keratoplasty. Results: The median follow-up after keratoplasty was 3.1 years (interquartile range [IQR], 9 months to 9 years). The median best-corrected visual acuity (BCVA) was 0.18 (IQR, 0.10�48) (Snellen equivalent 20/30 [IQR, 20/25�/60]) at 4 years postoperatively and 0.65 (IQR, 0.18-0.95) (Snellen equivalent 20/89 [IQR, 20/30�/178]) at 10 years following surgery. DALK eyes had a significantly better BCVA than PK eyes at 2 years following keratoplasty. The median overall survival of grafts was 15.8 years. Late complications included recurrence of LCD (14 eyes), graft infiltrate (23 eyes), graft rejection (15 eyes), graft failure (16 eyes), and glaucoma (14 eyes). Conclusion: The outcomes of graft are similar following PK and deep anterior lamellar keratoplasty; however, the latter appears to provide slightly better visual outcome. Recurrence of dystrophy in the graft and graft infiltrates limit the overall graft survival in both the groups.
ABSTRACT
Amniotic membrane transplantation is a useful in the management of corneal melts and descemetocele. We describe high-resolution anterior segment optical coherence tomography (OCT) (Optovue) in a patient with descemetocele who was managed surgically with amniotic membrane transplantation. A 60-year-old female presented with a corneal melt in the right eye. She was a case of rheumatoid arthritis and was on systemic treatment with immunomodulators. Slit lamp examination revealed a severe thinning paracentrally. High-resolution OCT was performed at the site of descemetocele. She underwent amniotic membrane transplantation using fibrin glue and bandage contact lens application. At 6 weeks postoperative, the bandage contact lens was removed. The area of thinning healed with scarring. OCT at the healed site revealed stable surface and an increase in stromal thickness to 281 ? this case describes the utility of amniotic membrane in the healing of sterile corneal melts by providing tectonic support and its integration in the stroma. The stromal healing and increased thickness at the site of descemetocele could be delineated on high-resolution OCT imaging.
ABSTRACT
We describe a case of 55-year-old male farmer presented with recurrent corneal abrasions with a spastic entropion in the left eye. Superior cornea showed typical nummular opacities suggestive resolved herpetic eye diseases. On further enquiry, he had similar episodes in the past. Contralateral eye was essentially normal. Following the botulinum toxin injection for the management of spastic entropion, subject developed reactivation of herpetic necrotizing stromal keratitis. Diagnostic corneal scrapings were negative for herpes simplex virus-1 antigen by immunofluorescence assay and for DNA by molecular techniques. The case was successfully managed with topical steroids and antiviral medications.
