In this series, cataract surgery could be safely performed with no major intra- or postoperative complications. While the surgical intervention itself was not associated with acute exacerbations of inflammation, progression of disease was noted in some cases over time. In spite of ongoing disease, cataract surgery in OCP was associated with stable visual outcomes.
An 11-year-old girl presented to our tertiary eye care centre with a 9-month-old history of lime injury in the left eye in 1999 with vision of counting fingers close to the face. She initially underwent superficial keratectomy with amniotic membrane graft in 1999. Subsequently, cultivated limbal epithelial transplantation was performed in 2001 which improved her vision to 20/400. Following development of pannus and symblepharon in the left eye, she underwent pannus resection and conjunctival limbal autograft in 2002 and, a month later, optical penetrating keratoplasty (PK) following which her vision improved to 20/125. She was under regular follow-up, underwent exotropia correction and subsequent levator palpebrae superioris resection for ptosis and was maintaining good vision. On her last follow-up 14 years after PK in 2016, her vision in the left eye was 20/40 with lipid keratopathy and her right eye showed no signs of focal limbal stem cell deficiency.
Ectatic corneal diseases are a group of
eye disorders characterized
by progressive thinning and outward bulging of the cornea, resulting
in vision impairment. A few attempts have been made to use cornea-derived
extracellular matrix hydrogels for corneal tissue engineering; however,
no studies have investigated its application in corneal ectasia. In
this study, we have first developed an animal surgical model that
mimics a few specific phenotypes of ectatic cornea. Later, we investigated
the potential of decellularized cornea matrix hydrogels (dCMH) from
both human and bovine sources in increasing the thickness of the cornea
in the developed surgical model. Our data advocate that surgical stromal
depletion can be followed to establish ectatic models and can also
provide information on the biocompatibility of materials, its integration
with native stroma, degradation over time, and tissue remodeling.
We observed that dCMH from both sources could integrate with ectatic
thin corneal stroma and helps in regaining the thickness by regenerating
a reasonably functional and transparent stroma; however, no significant
difference was spotted between the dCMH made from human and bovine
corneal tissue sources. Hence, this study is a promising step toward
developing a non-invasive technique for the treatment of corneal ectasia
by using dCMH.
Parasitic infections of the eye are rare. However, being more commonly seen in developing nations, they require active measures for screening, diagnosis, and therapy. Parasites of importance causing external ocular disease are protozoan parasites, such as Leishmania; metazoans, such as nematodes (roundworms), cestodes (tapeworms), and trematodes (flatworms); or ectoparasites, such as Phthirus pubis and Demodex.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
