[Bullous form of X-linked congenital retinoschisis in infants]
Insights
Bullous X-linked congenital retinoschisis in infants typically resolves favorably. Giant retinal cysts often collapse, with most patients experiencing good visual acuity, suggesting conservative management is preferred.
Area of Science:
- Ophthalmology
- Genetics
- Pediatrics
Background:
- X-linked congenital retinoschisis is a genetic disorder affecting vision.
- Bullous retinoschisis presents with retinal cysts in infants.
- Understanding the clinical course is crucial for management decisions.
Purpose of the Study:
- To describe the clinical manifestations and long-term course of bullous X-linked congenital retinoschisis.
- To evaluate visual function and outcomes in affected infants.
- To inform treatment recommendations for this condition.
Main Methods:
- Prospective study of 10 infants (6-18 months) with bullous X-linked congenital retinoschisis.
- Assessment of visual function using electroretinogram and visual evoked potentials.
- Longitudinal follow-up for an average of 7.65 years.
Main Results:
- Giant retinal cysts were present in 40% of patients under 3 years old.
- Retinal cyst collapse occurred in 85% of children, with 20% experiencing hemophthalmia.
- Visual acuity at 6-12 years was 0.36 +/- 0.23, indicating a generally favorable prognosis.
Conclusions:
- Bullous X-linked congenital retinoschisis has a favorable prognosis.
- Conservative management is recommended for infants unless negative changes occur.
- Surgical intervention or laser coagulation is generally not advised in infants.
Abstract:
Clinical manifestations and course of bullous X-linked congenital retinoschisis were studied in 10 infants aged 6-18 months. Visual function was evaluated by registration of electroretinogram and visual evoked potentials. The patients were followed up for 7.65 +/- 2.51 years. Giant retinal cysts were observed in 40% patients with X-linked retinoschisis aged under 3 years. Collapse (spontaneous or after laser coagulation of the retina) of retinal cysts with formation of demarcation pigmented lines was observed in 85% children. Twenty percent patients developed hemophthalmia which was completely resorbed within 4-12 months. At the age of 6-12 years visual acuity was 0.36 +/- 0.23. The prognosis of the condition is favorable, and therefore surgical treatment or laser coagulation are not recommended in infants with bullous retinoschisis, on condition that no negative changes in the disease course are observed.
