Abstract:
Introduction: Intrastromal corneal cyst (ISCC) is very rare corneal pathology. There
are only 16-17 cases described in the literature. ISCC may be primary (congenital) or
secondary (acquired) as a result of injury, inflammatory process etc. The diagnostics
& treatment rather difficult due to rarity observations. The item of this work was to
work out the diagnostic criteria & treatment possibilities of ISCC.
Material and methods: Child H., 8y.o. with intermittent corneal opacification was
carried out a full ophthalmological examination & surgical treatment.
Results: Complaints: the reduction of visual acuity of the right eye, intermittent
corneal clouding with a tendency to increase.
Objectively: blepharospasm, photophobia, mixed injection, 2 cystic formation of the
limbus at 6 o`clock ongoing intrastromal pseudohypopion. Visual acuity – 0.06
uncorrected, IOP – 15.0mm. US-scan revealed intrastromal corneal cystic cavity.
Treatment: I stage – conservative antibiotic & inflammatory therapy – without
success.
II stage – surgical intervention revision of the scleral cyst drainage & BSS sodium
solution irrigation the ISCC with closed cryodestruction of corneal & scleral cysts.
After operation – residual corneal clouding. Visual acuity rised to 0.2.
Conclusion
1. The migration of epithelial cells into the corneal stroma with its subsequent
proliferation plays a key role in ISCC formation.
2. The drainage of ISCC with BSS solution irrigation & closed cryodestruction – the
safest method of treatment in pediatrics.
