Congenital aniridia is a rare bilateral ocular malformation characterized by the partial or complete absence of the iris and is frequently associated with various anomalies, including keratopathy, cataract, glaucoma, and foveal and optic nerve hypoplasia. Additionally, nearly 50% of individuals with congenital aniridia experience symptoms of ocular dryness. Traditional treatment encompasses artificial tears and autologous serum. This study aimed to assess the effectiveness and safety of using platelet rich in growth factors (PRGF) plasma in patients with congenital aniridia and ocular dryness symptoms.
The included patients underwent two cycles of a 3-month PRGF treatment. At 6 months, symptomatology was evaluated using the OSDI and SANDE questionnaires, and ocular surface parameters were analyzed.
The OSDI and SANDE values for frequency and severity demonstrated statistically significant improvements ( < 0.05). Ocular redness, corneal damage (corneal staining), and tear volume (Schirmer test) also exhibited statistically significant improvements ( < 0.05). No significant changes were observed in visual acuity or in the grade of meibomian gland loss.
The use of PRGF in patients with congenital aniridia and ocular dryness symptoms led to significant improvements in symptomatology, ocular redness, and ocular damage. No adverse effects were observed during the use of PRGF.
先天性无虹膜是一种罕见的双侧眼部畸形,其特征为虹膜部分或完全缺失,常伴有多种异常,包括角膜病变、白内障、青光眼以及黄斑和视神经发育不全。此外,近50%的先天性无虹膜患者会出现眼干症状。传统治疗方法包括使用人工泪液和自体血清。本研究旨在评估富含生长因子(PRGF)的血浆对先天性无虹膜且有眼干症状患者的有效性和安全性。
纳入的患者接受了两个为期3个月的PRGF治疗周期。在6个月时,使用眼表疾病指数(OSDI)和SANDE问卷评估症状,并分析眼表参数。
OSDI和SANDE问卷中关于频率和严重程度的值显示出统计学上的显著改善(P<0.05)。眼红、角膜损伤(角膜染色)和泪液量(泪液分泌试验)也有统计学上的显著改善(P<0.05)。视力或睑板腺缺失程度未观察到显著变化。
对先天性无虹膜且有眼干症状的患者使用PRGF可显著改善症状、眼红和眼部损伤。使用PRGF期间未观察到不良反应。
