Observation of long-term efficacy of corneal limbal conjunctival autografts in microscopy treatments of pterygium.

Purpose: To compare the long-term efficacy of a corneal limbal conjunctival autograft combined with pterygium excision in the treatment of primary pterygium.

Methods: This random control study included 63 patients (63 eyes) with primary pterygium. These were randomly divided into a group with corneal limbal conjunctival autograft combined with pterygium excision (group A) and a group with pterygium excision with exposed sclera (group B) and subjected to long-term follow up.

Long-term outcomes of domestic hunan aqueous drainage implantation in refractory glaucoma.

Purpose: To evaluate the long-term outcomes of a non-valved, Chinese-made Hunan aqueous drainage device (HAD) in patients with refractory glaucoma, compared to trabeculectomy.

Methods: This was a retrospective observational case series, including 27 patients with refractory glaucoma who either underwent HAD implantation (n=11) or trabeculectomy (n=16). The mean follow-up was 27.
