What characterises the obstructive form of meibomian gland dysfunction?
The commonest form involves hyperkeratinization and plugging of orifices, so meibum thickens, stagnates and becomes hard to express even with manual pressure.
Meibomian Gland Dysfunction: The Oil Problem Behind Most Dry Eye
When is imaging of the orbit and brain warranted in sensory strabismus?
If the ocular findings do not adequately account for the degree of vision loss, an intracranial or orbital process affecting the visual pathway must be excluded.
Sensory Strabismus: When Poor Vision Causes the Misalignment
What is the role of high-dose systemic corticosteroids in vasculitis-associated necrotizing scleritis?
High-dose systemic corticosteroids gain initial control of the inflammation but are not adequate as sole long-term therapy when systemic vasculitis underlies the disease.
Necrotizing Scleritis: Why Immunosuppression, Not Just Steroids, Is the Treatment
Which examination technique is essential to identify a retinal dialysis?
Careful scleral depression around the whole periphery, especially inferotemporally, reveals the characteristic crescent of bare, disinserted retinal edge at the ora serrata.
Retinal Dialysis: The Slow-Motion Detachment at the Ora Serrata
What is the inheritance pattern of gelatinous drop-like corneal dystrophy?
Inheritance is autosomal recessive, so a supportive family history and parental consanguinity in some populations are relevant diagnostic clues, and genetic counselling should be offered to at-risk relatives.
Gelatinous Drop-Like Corneal Dystrophy: An Amyloid Disease That Mimics Something Far More Common
Why must OCT nerve fibre layer values be read cautiously in peripapillary staphyloma?
OCT of the nerve and retinal nerve fibre layer is interpreted cautiously because normative databases are not designed for this anomalous disc architecture.
Peripapillary Staphyloma: A Deep Excavation That Is Not Glaucoma
On serial optic nerve imaging, peripapillary staphyloma shows which behaviour?
Staphyloma is present from birth and stable, so OCT and serial photography show a static appearance, in contrast to the progressive rim thinning of glaucoma.
Peripapillary Staphyloma: A Deep Excavation That Is Not Glaucoma
When map-dot-fingerprint dystrophy blurs vision, what mechanism is responsible?
When the changes involve the central visual axis densely enough to distort the corneal surface, patients report mild fluctuating blur caused by irregular astigmatism.
