Unilaterally swollen eyes were histopathologically characterized in four MG-W gerbils. The primary lesions resided in the anterior segment of the eye where neural crest cells play a critical role in embryonic development. They included indistinct filtration angle, unformed canal of Schlemm, hypoplastic iris, and ciliary body. The findings noted in the retina, optic nerve, optic tract, and lateral geniculate nucleus were consistent with the lesions induced following the persistent elevation of intraocular pressure as a result of insufficient drainage of aqueous humor. Thus, the present cases observed in the eyes of MG-W gerbils exemplified the anterior segment dysmorphogenesis associated with inadequate neural crest migration or differentiation, leading to subsequent glaucoma.

Background: Refractory corneal edema is the foremost reason for endothelial corneal transplantation (EK) in the world. Descemet membrane endothelial keratoplasty (DMEK) and Descemet stripping automated endothelial keratoplasty (DSAEK) offer good clinical outcomes. However, human donor tissue is limited in availability and has a complex logistical chain.

Purpose: Atovaquone is an alternative drug that is used for the prevention and treatment of pneumonia when the first-line drug, sulfamethoxazole-trimethoprim (ST combination), cannot be used due to side effects. However, atovaquone is known to cause ocular side effects including oculomucocutaneous syndrome and vortex keratopathy. In this report, we describe a patient who developed bilateral white granular diffuse corneal opacity that extended from the corneal sub-epithelium to the stroma after continuous oral atovaquone administration for 14 months.

Vertical maxillary excess (VME) is a facial condition characterized by an increased height in the lower third of the face, leading to a longer overall facial appearance. This condition is linked to a significant proportion of malocclusions and is often associated with greater dissatisfaction among patients concerning their appearance. The amalgamation of orthodontics with surgery is a desirable protocol to address VME.
