Practice questions
- Which statement best reflects current understanding of scleral changes in myopia?
- A researcher wishes to monitor scleral biomechanical changes in a living adolescent with progressive myopia. Which statement best describes the present limitation?
- Why can an ex-vivo scleral biomechanical measurement method not, by itself, provide direct monitoring of a patient's living eye?
- Which research priority is specifically highlighted for future clinical application of scleral biomechanics assessment in myopia?
- Which set of indocyanine green angiography findings is described as characteristic of central serous chorioretinopathy?
- An eye with central serous chorioretinopathy has an increased choroidal thickness on OCT. Which explanation is reported in the reviewed literature?
- A review reports thicker sclera in eyes with CSC than in normal eyes and proposes that it may contribute to choroidal circulatory disturbance. How should this association be interpreted?
- Which emerging view of the sclera is described in a recent review of glaucoma therapy?
- A prostaglandin analogue is discussed as potentially facilitating uveoscleral outflow. Which scleral effect is described as a possible mechanism?
- Which combination best represents translational challenges that have limited widespread clinical adoption of transscleral strategies?
- Which group consists entirely of transscleral drug-delivery approaches highlighted as emerging in the review?
- In glaucoma, where does optic nerve damage principally begin according to the review of optic nerve head and scleral biomechanics?
- A dog model of open-angle glaucoma associated with an ADAMTS10 mutation is discussed in relation to disease progression. Which observation is reported?
- In Beagles with ADAMTS10-associated open-angle glaucoma, which posterior scleral findings were reported before glaucoma development?
- In a controlled Wood's lamp study of favipiravir exposure, what proportion of patients had scleral fluorescence?
- A patient reports a prior full course of favipiravir several months ago. Which statement about Wood's lamp fluorescence is consistent with the controlled study?
- Which statement best summarizes the controlled comparison of Wood's lamp fluorescence after favipiravir exposure?
- Which option correctly matches the three scleral IOL fixation approaches reviewed in the clinical literature?
- In a retrospective series comparing three scleral IOL fixation methods, which outcome was reported across the overall cohort?
- Which statement about the need for revision after scleral IOL fixation is supported by the reported clinical series?
- Which technologies have improved characterization of anterior-eye anatomy relevant to scleral lens practice?
- A clinician is planning scleral lens fitting in an eye with an irregular anterior ocular surface. Which approach is most consistent with the review's discussion of modern fitting practice?
- What is the purpose of modifying scleral lens design in response to fitting challenges, as described in the review?
- A structural comparison of human sclera and tendon identifies which shared features?
- Which interpretation best captures the sclera-tendon comparison in the review?
- Which statement best distinguishes the current therapeutic promise of scleral drug delivery from its present clinical status?
