RESUMO
Anterior segment optical coherence tomography (ASOCT) is an imaging modality that provides both quantitative and qualitative information on the cornea, anterior chamber angle, iris and crystalline lens. ASOCT shows excellent repeatability and reproducibility for the measurement of corneal thickness, anterior chamber angle and anterior chamber depth. With realtime video recording, ASOCT can also effectively capture the dynamic changes of the iris and lens in response to light and eye accommodation. With this additional information, physiological and pathological changes of the anterior segment structures are now better understood. This article aims to provide an overview of the current applications of ASOCT in glaucoma. HOW TO CITE THIS ARTICLE: Li H, Jhanji V, Dorairaj S, Liu A, Lam DSC, Leung CK.

RESUMO
A 34-year-old woman, with preceding flu-like febrile illness, developed acute macular neuroretinopathy in her left eye with typical reddish brown macular lesions and a dense paracentral scotoma. Her condition was evaluated with multifocal electroretinogram and optical coherence tomography in her acute and recovery phases. The findings assist ophthalmologists striving for better understanding and diagnosis of acute macular neuroretinopathy.

PURPOSE: To describe clinical outcomes after a novel type of corneal surgery, implantation of an artificial cornea, AlphaCor , and to evaluate outcomes in comparison with alternative keratoprostheses and high-risk grafts. METHODS: Case reports and data from a noncontrolled clinical trial and a literature review. RESULTS: The probability of AlphaCor retention to 1 year is 80%. Postoperative best corrected visual acuity ranges from Perception Light to 20/30. The most significant complications are stromal melts and optic depositions, for both of which the main risk factors have been identified. Complications can be managed without loss of the eye. CONCLUSION: Results from the clinical trial period have helped to determine the indications and risk factors for AlphaCor surgery and to refine surgical techniques. Continued monitoring of outcomes as the series increases will allow a more accurate determination of comparative outcomes. The series provides preliminary evidence that AlphaCor may have a lower incidence of complications than traditional keratoprostheses and may prove to be preferable to a donor graft in high-risk cases.
