Ocular Shape of Cataract with Retinitis Pigmentosa: A Case-Control Study
Purpose:
To investigate the anterior segment morphology in cataracts with Retinitis Pigmentosa (RP).
Setting:
XXXX (anonymized for review) University Hospital.
Design:
A retrospective
Methods:
The analysis included 28 eyes of 28 patients with cataracts and RP and 28 eyes of 28 patients with cataracts but without RP, matched for age and sex. Lens thickness, anterior lens curvature (Front R), posterior lens curvature, anterior chamber depth (ACD), anterior chamber width, central corneal thickness (CCT), white-to-white distance (WTW), corneal curvature, and axial length (AL) were compared between the groups. Data were obtained from preoperative evaluations conducted before cataract surgery. The same set of comparisons was also conducted for 18 eyes of 18 patients with cataracts and RP and 18 eyes of 18 patients with cataracts but without RP, matched for age, sex, and AL. Cases including missing data, categorized as Emery–Little classification grade 4 or above, or those with a history of acute angle closure were excluded.
Results:
In the age-
Conclusions:
Cataracts with RP demonstrated centripetal swelling of the lens, centrifugal corneal thinning, and AL shortening. A decrease in tension between the lens and eyeball wall due to zonular weakness in the RP may lead to swelling of the lens and horizontal flattening of the eyeball.
