Purpose. To evaluate Fourier-domain optical coherence tomography (FD-OCT) as an adjunct to traditional slit lamp examination of donor corneas with suspected Anterior Stromal Opacities.Methods. Seven corneas suspected of having anterior stromal opacities by slit lamp examination were evaluated with FD-OCT. Each cornea was evaluated to confirm the presence of opacity and, if present, the depth of opacity was measured.Results. The opacity depth ranged from 82 μm to 624 μm. The initial slit lamp impressions of five of the seven corneas were confirmed by OCT. In two corneas, the OCT findings were different from the initial slit lamp impressions. Slit lamp examination of the first cornea gave the impression of anterior stromal scarring, but OCT showed that the opacity was limited to the epithelium. Slit lamp examination of the second cornea suggested opacity limited to the epithelium, but OCT identified significant sub-Bowman's scarring. In all cases, the Eye Bank Technicians reported that the location and depth of corneal opacity were more sharply defined by OCT than by slit lamp.Conclusion. The high resolution of OCT makes it easier to determine the location of corneal opacities compared to slit lamp examinations. This enhanced visualization can improve decisions regarding transplant suitability of donor corneas.

An atypical case of acute posterior multifocal placoid pigment epitheliopathy with a clear reappearance of the ellipsoid layer of the retina after Ozurdex® intravitreal implantation is presented. A 51-year-old woman reported a 3-week history of left eye photopsia. On slit-lamp examination, yellowish placoid lesions were found on her left eye fundus. Ancillary tests were performed. The patient was diagnosed as a left eye acute posterior multifocal placoid pigment epitheliopathy, and observational approach was decided. Later, the condition started to progress in an ampiginous manner and a decrease of visual acuity caused by an increase in number and size of the lesions was observed. As the disease was progressing with the conservative, observational approach, and the macula was menaced, an intravitreal dexamethasone implant was injected in the left eye with a consequent improvement of the visual acuity and lesion stabilization. The ellipsoid layer, unidentifiable inside the placoid lesions in previous optical coherence tomography tests, reappeared after the treatment. Intravitreal dexamethasone implants can be used to stabilize acute posterior multifocal placoid pigment epitheliopathy lesions and help resolve the condition. Spectral domain optical coherence tomography can also be useful for monitoring these lesions, as the ellipsoid layer may reappear upon resolution.
