Sclera

open access: yes, 2018
‘Sclera’ provides the reader with a practical approach to the assessment and management of scleral disease. After outlining the relevant anatomy and physiology of this structure, the chapter addresses the key clinical presentations arising from scleral disease, notably episcleritis, anterior scleritis and posterior scleritis.

Sclera-Net: Accurate Sclera Segmentation in Various Sensor Images Based on Residual Encoder and Decoder Network

open access: yesIEEE Access, 2019
Sclera segmentation is revealed to be of noteworthy importance for ocular biometrics. The paramount step for biometric recognition methods is the segmentation of the area of interest, i.e., the sclera in our case.

Modified balanced two-string technique of internal scleral fixation of posteriorly dislocated intraocular lens

open access: yesIndian Journal of Ophthalmology, 2021
Posterior dislocation of the intraocular lens (IOL) is a rare but potentially dangerous complication encountered by a cataract surgeon. We describe a modified balanced two-string technique of internally fixing a posteriorly dislocated rigid IOL using the

Form-deprivation myopia induces decreased expression of bone morphogenetic protein-2, 5 in guinea pig sclera

open access: yesInternational Journal of Ophthalmology, 2015
AIM: To identify the presence of various bone morphogenetic proteins (BMPs) and their receptors in normal sclera of human, rat and guinea pigs, and to determine whether their expression changed with form-deprivation myopia (FDM) in guinea pig sclera ...
