Purpose: To describe the petal-shaped corneal pattern in a patient with posterior amorphous corneal dystrophy.
Observation: A 19-year-old male affected by Graves' disease presented corneal grey sheet-like opacities and high hyperopia. Corneal topography showed reduced k-values compatible with cornea plana and reduced corneal pachymetry. The anterior segment optical coherence tomography showed a hyperreflective band at the posterior stroma-Descemet-Endothelium layers in both eyes. Slit lamp examination with cobalt blue filter showed a corneal pattern resembling a petal in right eye; the pattern was similar but incomplete in left eye.
Conclusion & Importance: After an exhaustive literature review conducted from October 1st to 30th, 2023, utilizing online databases like PubMed and Google Scholar, and employing keywords such as "Corneal Dystrophy," "Slit Lamp," "Cornea," and "Posterior Amorphous Corneal Dystrophy," we found no previous reports detailing the whole corneal pattern using a blue cobalt filter on the slit lamp in cases of posterior amorphous corneal dystrophy. Cobalt blue filter was an effective method for capturing the full photographic corneal pattern of the patient posterior amorphous corneal dystrophy.

Corneal ulcer is one of the most important ophthalmic emergencies. A portable, recordable, and smartphone-attachable slit-lamp device called the "Smart Eye Camera" (SEC) is introduced to compare evaluating corneal ulcers between the SEC and the conventional slit-lamp. A total of 110 participants were included in the study, consisting of 55 patients with corneal ulcers and 55 age- and gender-matched healthy volunteers as controls.

Background: Scientific evidence to guide clinicians on the use of different antiseizure drugs in combination therapy is either very limited or lacking. In this study, the impact of lacosamide and perampanel alone and in combination was tested in corneal kindling model in mice, which is a cost-effective mechanism for screening of antiseizure drugs.
Methods: The impact of lacosamide (5 mg/kg) and perampanel (0.
