Pediatric keratoplasty.

Penetrating keratoplasty in children is a highly challenging and demanding procedure associated with a high risk of graft failure or failure of amblyopia therapy in clear grafts. Nonetheless, keratoplasty remains the surgery of choice for the management of pediatric corneal stromal opacities or edema. Allograft rejection, graft infection, corneal neovascularization, glaucoma, trauma to the anterior segment, vitreous pathology, and additional surgical interventions, especially those related to glaucoma management, are important risk factors.

Viscoexpression of large free floating Cysticercus cyst from the anterior chamber of the eye by double incision technique.

We describe a case of 16-year-old girl who reported with diminution of vision in left eye for past seven months with appearance of white reflex. Slit lamp biomicroscopy revealed the presence of a live grayish white cyst in the anterior chamber. The ultrabiomicroscopic evaluation revealed a large live Cysticercus cellulosae cyst in anterior chamber.

Polymerase chain reaction-guided diagnosis of mycotic keratitis: a prospective evaluation of its efficacy and limitations.

Purpose: To assess the utility of polymerase chain reaction (PCR) in diagnosing fungal keratitis and compare its sensitivity and specificity with those of the conventional microbiologic techniques used in the authors' laboratory.

Methods: A prospective nonrandomized investigation was undertaken at a tertiary-care ophthalmic facility to evaluate 40 eyes of 40 patients with presumed fungal keratitis, both fresh and treated. Besides routine bacterial culture and sensitivity, corneal scrapings were evaluated by fungal culture, potassium hydroxide (KOH) wet mount, Gram's stain, and PCR.

Anterior segment OCT-based diagnosis and management of retained Descemet's membrane following penetrating keratoplasty.

Purpose: To report a case of retained Descemet's membrane after penetrating keratoplasty for congenital hereditary endothelial dystrophy (CHED) documented by anterior segment optical coherence tomography and review of literature.

Methods: Case report and review of literature.

Results: A 14-year-old boy underwent penetrating keratoplasty for CHED.

Intracameral SF6 injection and anterior segment OCT-based documentation for acute hydrops management in pellucid marginal corneal degeneration.

Purpose: To report a case of acute hydrops in pellucid marginal corneal degeneration (PMCD) documented with anterior segment optical segment tomography and successfully treated with sulphur hexafluoride (SF6) intracameral injection.

Methods: A 47-year-old female patient presented with spontaneous onset of pain, redness and decreased vision in her left eye. Clinical evaluation revealed bilateral PMCD with evidence of acute hydrops in the left eye.
