Corneal Ectasias and Degenerations

White linear radial stromal haze caused by infiltration and inflammation of the corneal nerves by the amoeba.

The bee stinger seen in the cornea has remained stable for many years and not affected the vision or required removal.

Slit lamp photo post LASIK surgery 2 months prior showing patches of cellular material in the the cornea, worse inferiorly. The anterior segment OCT demonstrates the level of the ingrowth is in the interface of the flap.

The patient presented with corneal edema and descemet's folds. The patient noted that she was gardening, and the offending contact was likely euphorbia cyparissias plant sap.

Post penetrating keratoplasty for candida keratitis, this patient developed another foci of infection within the graft tissue. Stromal vascularization and edema can be seen indication failure of the graft.

Keratoprosthesis infiltrate and epithelial defect. There was progression with pain and and vitritis that led to removal of the prosthesis.

This patient underwent uneventful cataract surgery. On post-operative day 1 there was found to be a fragment of metal on the iris likely from the phacoemulsification probe.

Inferior peripheral corneal thinning due to systemic inflammatory disease. Surgery was with conjunctival recession and amniotic membrane placement.

Peripheral crescentic ulceration and thinning along limbus from 0600 to 1200 with superior neovascularization associated with pain. Treatment was initially with lubrication, antibiotic, systemic steroids, vitamin C, and doxycycline. Ultimately, the patient needed conjunctival recession with AMT pla…

Patient with history of multiple retinal detachments with a phthisis eye. The crystalline lens is noted to have migrated external to the sclera and subconjunctivally.

Iridocorneal Endothelial Syndrome (ICE) A 27-year-old woman presented for corneal evaluation with a history of secondary glaucoma. She was found to have iridocorneal endothelial syndrome (ICE). She underwent DSAEK, which failed after 13 months. Subsequent Type 1 Boston Keratoprosthesis was successf…
