Featured Photo: What is the diagnosis?
Hypotony: Late hypotony from trabeculectomy and Ahmed seton with resulting hypotony maculopathy: 36-year old female presented with poor vision secondary to a low intraocular pressure (IOP) in her right eye.
Appropriate Scleral Lens Sagittal Depth: Scleral contact lenses rest on the sclera, vaulting over the entire cornea and limbus to avoid irritating or scarring those tissues.
Intradermal Nevus, combined type with mild atypia: Abnormal puncta was noted on annual eye exam. Patient had not noticed it nor had her prior eye care provider mentioned it to her.
Laser Pointer Maculopathy: 16-year-old male who suffered a laser pointer injury to his right eye and subsequently found that he had a small central area of "blackness" that made it difficult to read.
Scleral Lens Touch: A major benefit of scleral RGP contact lenses over corneal RGP contact lenses is that scleral lenses completely vault the cornea. This is beneficial in dry eyes because it places the cornea under water, in keratoconus because a contact lens that rubs induces scarring, and in fitting highly irregular shapes that would not allow for centration with a corneal lens.
Tadpole Pupil: A tadpole pupil occurs with segmental spasm of the iris dilator muscle producing episodic pupillary distortion, often in the shape of a tadpole.
New Patient Tutorial:
Vision Rehabilitation Technlogy: Low vision technology is now changing at a rapid pace. With this in mind, the information in this document will be updated as often as possible.
