Partial Cryoablation on Retionpathy of Prematurity

Although the reports of the use of crotherapy in the control of the proliferative phase of retinopathy of prematurity varied in their conclusions regarding the merits and limitations of this therapy, cryotherapy has been consedered to be an effective treatment for retinopathy stage 3. The accepted method of therapy includes ablation of the whole avascular retina from the ridge to the ora serrata. This is achieved by 2 to 3 rows of cryoapplications with use of cryotherapy probe for ROP. Nissenkorn et al presented their new method of cryotherapy in which only one row of cryoapplications was applied in the avascular retina anterior to the fibrovascular ridge. So, we performed cryotherapy using Nessenkorn's new method on 7 babies and the anatomical results are reviewed. Complete regression of active retinopathy was achieved in all of the eyes treated.

The Effect of Antibiotic and Steroid Drops Following Strabismus Surgery

Many opthalmologists prefer to treat the eyes operated on with drops containing corticosteroids and antibiotics for a few days of a few weeks after strabismus surgery. But no controlled studies are available to support the rationale for such therapy. Therefore, we conducted a prespective double-blind masked trial to evaluate the clinical effectiveness of the drops containing antibiotics and steroid on 40 patients. There are no singnificant difference between the drug and the placebo groups.

A Case of Acquired Brown's Syndrome Caused by Tenosynovitis

Brown's syndrome is characterized by inability to elevate the adducted eye and positive forced duction test. It is known as congenital disease but may occur as acquired disease Acquired Brown's syndrome may occur after superior oblique muscle tucking, frontal sinusitis, surgery of frontal sinus or orbit, scleral buckling, and inflammation in trochlear area. Brown's syndrome caused by inflammation of trochlear area is frequently combined with rheumatoid arthritis. The ocular motiliy is improved after systemic corticosteroid treatment or local injection of corticosteroid in trochlear area. An llyear old korean girl was found to have bilateral aquired Brown's syndrome caused by tenosynovitis. There were severe limitation of elevation in adduction and resistance in forced duction test in both eyes. The ocular motility was improved after local injection of dexamethasone in trochlear area.

Implantation of Posterior Chamber Intraocular Lens by Trans-Scleral Fixation

We performed trans scleral fixation techniques for implantation of posterior chamber lens in 25 eyes, in case of incomplete zonular or capsular support. This was done by securing both haptics of the posterior chamber lens to the sclera at the ciliary sulcus with 10-Onylon suture. Postoperative follow-up time ranged from 12 to 23 months, with all patients having at least one year of follow up. At the last follow up visit, 16 eyes (72%) had a vision of 20/50 or better, and 13 eyes (52%) had a vision of 20/30 or better. The transscleral fixation related complications included retinal detatchment, glaucoma and cystoid macular edema. During the relatively longterm follow up period, we did not find any serious complications due to the intraocular lens and there was no significant postoperative changes in the visual acuities.
