ABSTRACT
AIM:
To investigate the postoperative ocular surface changes in acute attack
eye and contralateral
eye with primary
angle-closure glaucoma(PACG)and
cataract.
METHODS:
A total of 40
patients with monocular acute PACG combined with
cataract who admitted to Zhengzhou Central
Hospital Affiliated to Zhengzhou
University from January 2021 to January 2022 were selected.
Trabeculectomy combined with
phacoemulsification and
intraocular lens implantation was carried out in the acute attack
eyes, and
phacoemulsification and
intraocular lens implantation were carried out in the contralateral
eyes. The ocular surface
disease index(OSDI)
questionnaire, noninvasive first
tear film break-up
time(NifBUT), noninvasive average
tear film break-up
time(NiaBUT)and
tear meniscus height(TMH)were assessed preoperatively and 1, 3 and 6mo postoperatively.
RESULTS:
The OSDI scores of the included
patients at 1 and 3mo postoperatively(14.72±3.07, 11.39±2.24)were significantly higher than those preoperatively(9.68±1.98; all P<0.0083), and there was no significant difference between 6mo postoperatively(10.18±1.84)and preoperatively. NifBUT of the acute attack
eyes at 1 and 3mo postoperatively was significantly lower than that preoperatively, and NiaBUT of the acute attack
eyes at 1, 3 and 6mo postoperatively was significantly lower than that preoperatively(all P<0.0083). The NifBUT and NiaBUT of the contralateral
eyes at 1mo postoperatively were significantly lower than those preoperatively(all P<0.0083), and there was no significant difference between 3 and 6mo postoperatively and preoperatively. There was no significant difference in TMH of the attack
eyes and the contralateral
eyes postoperatively and preoperatively(P>0.05).
CONCLUSION:
The stability of
tear film after
surgery of PACG and
cataract is decreased. The acute attack
eye needs 6mo or even longer to recover, while the contralateral
eye needs roughly 3mo.
