Limbal-Conjunctival Autograft Transplantation for the Treatment of Primary Pterygium

Pterygium is a common surgical ocular disease which recurs frequently. Various different techniques have been developed for the successful surgical treatment of pterygium and among them, autograft transplantation is known as the best successful surgical method. For the prevention of recurrence, the corneal epithelium must heal before the fibrovascular tissue grows and reaches to limbus. For this, we have believed that limbal transplanta- tion is more suitable than conjunctival transplantation. We had performed limbal-conjunctival autograft trasplata- tion for 52 patients with primary pterygia whose age was under 40 years old,or whose pterygia had involved above 5mm beyond limbus and had shown diffuse subconjunctival fibrovascular tissue. The recurrence rate was 1.9%and therewere no complications and no surgical problems. Therefore,we recommend this surgical technique as a safe and effective method of treating primary pterygia with the risk factors of recurrence.

Comparison of Ocular Pain during Cataract Surgery Using a Scleral Pocket Incision under Pinpoint versus Intracameral Anesthesia

We compared the pain produced during different phases of phacoemulsification cataract surgery using a scleral pocket incision under pinpoint anesthesia with that under intracameral anesthesia. This prospective study comprised each 100 cataract patients who had no complications influencing the degree of pain during surgery. Patients were asked about pain immediately after each phase and pain occurring during each phase was measured using 4 step verbal scale(from 0 to 4). In both anesthesia,conjunctival reposition was the most painful.Pinpoint injection was statistically significantly more painful than induction of intracameral anesthesia.The pain score during conjunctival reposition and at 1hr after surgery were significantly higher under intracameral anesthesia than under pinpoint, but during most of phases under both anesthesia,the pain score was relatively low. Intracameral anesthesia is easy,safety and dose not require additional ocular damage during induction of anesthesia,so if combined with topical anesthesia,it is very effective during cataract surgery using scleral pocket incision.

Moyamoya Disease with Characteristic Funds Findings of Retinal Vascular Insufficiency

Moyamoya disease is characterized by progressive stenosis of internal carotid artery and shows unique angioraphic findings. Its etiology is still unknown, and theories of immunophysiologic and inflammatory mechanisms remain unproven. These patients show various neurologic symptons by cerebral ischemia, infarction and gemorrhage. and they also show various ophthalmologic symptoms. We experienced that a 21-year-old female who was diagnosed to have moyamoya disease presented with a suddenly developed occipital headache and neurologic deficit. The etiology of her characteristic fundus findings was thought to be retinal vascular insufficiency.
