Retroillumination photography is difficult. The reflections on the cornea and the lens are constant and prevent from obtaining a complete and clear image. Study team have modified a slit lamp intended to photograph the anterior segment of the eye in retroillumination by using a light source in the near infrared (780 nm), and a process which eliminates the reflections.

Inclusion Criteria:

• Patient with corneal pathology, crystalline pathology, or pigmentary glaucoma with transilluminable iris. In case of bilateral disease, both eyes will be photographed
• Patient having received an instillation of eye drops to dilate the pupil of the eye to be photographed (or of both eyes).

Exclusion Criteria:

• Major blepharospasm
• Poor or no pupillary dilation: patient with allergy or intolerance to eye drops used for pupillary dilation, refusal of pupillary dilation
• Pregnant or breastfeeding patient
• Person under legal protection
