The existing shortage of local donor corneas in our institution (University Malaya) and Malaysia, in general, prompted us to attempt the use of one donor cornea for two transplantation procedures; Descemet Stripping Endothelial Keratoplasty (DSEK) in a case of a pseudophakic bullous keratopathy (PBK) with underlying Fuchs endothelial dystrophy (FED) and lamellar patch graft in a case of limbal dermoid. The donor cornea was divided into anterior and posterior lamellae manually. The anterior corneal button was used as a patch graft for anterior lamellar keratoplasty in a 6-year-old patient with limbal dermoid, and the posterior corneal button was used for a DSEK procedure in a 68-year-old patient with corneal decompensation. Both patients had a stable and good visual outcome throughout a 1-year postoperative period. This allows the use of one corneal tissue by more than one recipient to overcome the shortage in donor corneas.

We report a literature review and a case of ocular toxoplasmosis in a patient with multiple drug allergies, who was successfully treated with regular intravitreal clindamycin and subconjunctival dexamethasone. A Malay lady in her twenties presented to us with right eye blurring of vision of 2 weeks duration, which she described as a central scotoma. Visual acuity at presentation was hand movements. Examination revealed intense ocular inflammation. The right eye had anterior segment inflammation of 3+ cells with fine keratic precipitates, whilst the posterior segment revealed papillitis, vitritis, retinitis, choroiditis, vasculitis and hyperpigmented chorioretinal scar inferotemporal to fovea. Ocular coherence tomography showed intraretinal fluid and retinal thickening. Fluorescein angiography showed early hypofluorescence of the lesion with progressive hyperfluorescence and leakage from the optic disc. Immunoglobulin G serology of Toxoplasma gondii was raised and immunoglobulin M levels were normal. The patient developed an allergic reaction with classical antibiotic and antifolate therapy. She was successfully treated with regular two-weekly intravitreal clindamycin and subconjunctival dexamethasone and her best corrected visual acuity was 6/18 at the end of her treatment. Intravitreal injection of clindamycin and subconjunctival dexamethasone is a good option in patients of ocular toxoplasmosis who are allergic to oral medications.
