Delayed postoperative interface keratitis due to Enterococcus faecalis after Descemet membrane endothelial keratoplasty.

To report the clinical course and management of interface keratitis due to Enterococcus faecalis after Descemet membrane endothelial keratoplasty (DMEK). A 64-year-old man underwent DMEK, with unevenful immediate postoperative course, with a visual recovery of 20/30 at 2 weeks. At 3 months of clinical visit, interface keratitis was noted. DMEK graft removal with stromal bed scrapings was performed. A diagnosis of E. faecalis interface keratitis was made. The patient responded favourably to antibiotic susceptibility-guided intensive treatment with vancomycin 5% with complete resolution of infection. After 2 months of graft removal, Descemet stripping endothelial keratoplasty (DSEK) was performed. The corneal clarity was restored and the best corrected visual acuity was 20/40 at last follow-up of 1 year. E. faecalis should be kept as a differential in delayed onset interface keratitis after DMEK. After microbiological cure with antibiotic therapy, visual rehabilitation with DSEK restores corneal clarity and results in favourable visual outcome.

Oral mucous membrane grafts for total symblepharon and lid margin keratinisation post Stevens-Johnson syndrome.

A female patient in her late 40s presented with severe visual impairment and a history of oral ulcers, necrolysis of skin and hospitalisation after using gabapentin for neck pain 10 months ago. She was a diagnosed case of Stevens-Johnson syndrome (SJS) with chronic ocular sequelae-with total symblepharon and keratinised lid margins in the left eye and limbal stem cell deficiency and severe dryness in the right eye. Her visual acuity was perception of light in both eyes. She underwent left eye symblepharon release with autologous labial mucous membrane grafts (MMGs) for surface reconstruction and subsequent lid margin MMG for lid margin keratinisation. Best-corrected visual acuity improved to 20/25 with scleral lens in the left eye, which was sustained over 1 year of follow-up. Labial mucosa acts as a useful and easily accessible alternative to conjunctiva in eyes with bilateral severe ocular surface damage and total symblepharon secondary to SJS.

Idiopathic myelofibrosis causing inflammatory central retinal vein occlusion mimicking frosted branch angiitis.

Primary idiopathic myelofibrosis is a clonal disorder arising from the neoplastic transformation of early haematopoietic stem cells leading to abnormal fibrous tissue within bone marrow. We present a 51-year-old man complaining of sudden loss of vision in the right eye along with multiple superficial retinal haemorrhages and perivascular infiltration. Fundus fluorescein angiography and optical coherence tomography confirmed the diagnosis of inflammatory central retinal vein occlusion with macular oedema which mimicked frosted branch angiitis. Laboratory tests and bone marrow biopsy confirmed underlying systemic disease to be Janus kinase 2 mutation positive primary idiopathic myelofibrosis. He received one intravitreal injection of antivascular endothelial growth factor along with dexamethasone for his ocular condition. In view of his systemic disease, he was started on systemic chemotherapy and oral corticosteroid which helped in stabilising the eye condition.
