Partial-Thickness Intrastromal Lamellar Keratoplasty for Corneal Pellucid Marginal Degeneration.

PURPOSE: Pellucid marginal degeneration (PMD) is a bilateral corneal ectatic disorder, characterized by thinning of the inferior cornea. Numerous surgical procedures have been described in the literature, and there is a lack of consensus regarding the best available surgical management. Recently, full-thickness intrastromal lamellar keratoplasty (ILK) was described as an option for treating PMD and emerged as a promising technique. However, ILK results in an irregular surface, leading to a significant residual against-therule (ATR) astigmatism. METHODS: This study describes a variation of the ILK technique, using a partial-thickness graft to treat 2 cases of PMD. RESULTS: At the final follow-up, both patients improved visual acuity and had their mean simulated keratometry flattened, although a residual ATR astigmatism remained. CONCLUSIONS: The ILK technique modification might lead to a more regular thickness pattern, although it did not seem efficient in reducing the ATR astigmatism.

An unusual case of nine cilia embedded in the retina after a perforating ocular injury.

PURPOSE: To report an extremely rare case involving a 41-year-old man with nine intraocular cilia embedded in the retina after a perforating ocular injury caused by a metal wire. This case is particularly rare because of the number and location of the cilia. OBSERVATIONS: The patient underwent an uneventful corneal suturing and extracapsular extraction of the damaged lens of his right eye. Intraocular foreign bodies were discovered following surgery and were removed at a later date. Following lens extraction and ocular repair, the patient's best-corrected visual acuity (BCVA) was counting fingers. Fundus examination during follow-up revealed several eyelashes embedded in the retina. Thirty-two days after the injury, the patient showed signs of ocular inflammation. Therefore, the patient underwent vitrectomy and intraocular foreign body removal. Nine cilia were embedded in the retina at the posterior perforation site. At the final follow-up visit, his BCVA was 20/25. CONCLUSION AND IMPORTANCE: This report describes an unusual case where intraocular cilia were embedded in the retina after a perforating ocular injury. The eyelashes caused an intraocular inflammatory reaction that subsided after their removal.
