[Clinical analysis of Terson syndrome in infants].

Objective

To observe the clinical features, intervention and outcomes of anatomic and visual functions of Terson syndrome in infants, and to explore the appropriate timing for surgery.

Methods

This retrospective study included 23 eyes of 14 infants diagnosed with vitreous hemorrhage related to Terson syndrome between May 2008 and March 2021 in Department of Ophthalmology, Peking University People's Hospital. There were 7 males (11 eyes) and 7 females (12 eyes). The age at the initial visit was (4.59±3.96) months. No obvious abnormality was observed in the anterior segment of both eyes of each patient. Data were collected, including demographics, causes of intracranial hemorrhage, characteristics of intraocular hemorrhage, intervention, outcomes of anatomic and visual functions.

Results

The causes were craniocerebral trauma in 3 patients, idiopathic cysts in 8 patients, ependymal cyst rupture in 1 patient and respiratory distress in 2 patients. The chief complaint was behavior change in 9 patients, and hemorrhage was found in 5 patients on fundus examination. The rate of complications related to intraocular bleeding was 12/16 when the duration was less than 3 months and 6/7 when the duration was more than 3 months. Twenty eyes (86.96%) were treated by vitrectomy. The follow-up ranged from 6 to 160 months. Three eyes were atrophied, anatomical success was recorded in 18 eyes, and retinal detachment developed in 2 eyes. The visual acuity was improved in 12 eyes (60%), unchanged in 5 eyes (25%), and deteriorated in 3 eyes (15%), except 3 eyes that did not comply with visual acuity examination. Ten eyes showed an obvious myopic shift.

Conclusions

The vitreous hemorrhage related to Terson syndrome can occlude the macula and cause severe structural and functional impairments in infants. Vitrectomy is an effective intervention technique, which can quickly remove blood accumulation and restore the anatomical structure, providing better conditions for the visual development of infants.
