ABSTRACT
In this retrospective case series, the authors reviewed cases of patients with macular disorders whose eyes had been imaged using spectral domain optical coherence tomography (SD-OCT) (Cirrus HD-OCT; Carl Zeiss Meditec, Inc., Dublin, CA). SD-OCT images were obtained from patients with a variety of ocular conditions attending a tertiary retinal clinic in Singapore from August 2007 to December 2007, according to standardized protocols. Images of 428 eyes from 301 patients were reviewed. Ocular diagnoses included diabetic macular edema, exudative age-related macular degeneration, central serous chorioretinopathy, cystoid macular edema, retinal vein and artery occlusions, infective chorioretinitis, and others. The authors present four cases of particular interest to illustrate how SD-OCT was useful in complementing the clinician's assessment of macular disease.

We report 13 cases of ophthalmic complications resulting from dengue infection in Singapore. We performed a retrospective analysis of a series of 13 patients with dengue fever who had visual impairment. Investigations included Humphrey automated visual field analyzer, Amsler charting, fundus fluorescein angiography, and optical coherence tomography. Twenty-two eyes of 13 patients were affected. The mean age of patients was 31.7 years. Visual acuity varied from 20/25 to counting fingers only. Twelve patients (92.3%) noted central vision impairment. Onset of visual impairment coincided with the nadir of serum thrombocytopenia. Ophthalmologic findings include macular edema and blot hemorrhages (10), cotton wool spots (1), retinal vasculitis (4), exudative retinal detachment (2), and anterior uveitis (1). All patients recovered visual acuity to 20/30 or better with residual central scotoma by 12 weeks. These new complications suggest a widening spectrum of ophthalmic complications in dengue infection.

We present the first reported case of late recurrence of postoperative Enterococcus faecalis endophthalmitis after cataract surgery in a 45-year-old diabetic man. Culture-positive E faecalis endophthalmitis was diagnosed 2 days after uneventful phacoemulsification. Early vitrectomy with intravitreal and subconjunctival vancomycin and amikacin and topical vancomycin resulted in apparently complete clinical resolution after 4 months and a best corrected visual acuity of 20/25. Recurrent endophthalmitis with hypopyon occurred 7 months postoperatively and resolved with intravitreal vancomycin and topical prednisolone acetate 1%. However, the patient had a similar relapse at 9 months that resulted in deterioration of visual acuity to no light perception despite a repeat vitrectomy, intraocular lens explantation, capsular bag removal, and intravitreal antibiotics. The late recurrences could have been the result of persistent sequestration of the organism in the capsular bag.
