Purpose: To investigate the effect of intravitreal injection of triamcinolone acetonide (4 mg) on refractory uveitis with cystoid macular edema (CME). Methods: A retrospective observation survey was conducted on 21 eyes of 15 patients with refractory uveitis that had no response to immunosuppresants or systemic steroid therapy. Seven eyes were injected with triamcinolone acetonide intravitreally only, and fourteen eyes were injected during pars plana vitrectomy. At 3 and 12 months after triamcinolone acetonide injection, best corrected visual acuity and thickness of macula were measured by OCT. Results: The average pre-treatment best corrected visual acuity was 0.18±0.08, and the average macular thickness was 534±132 ?m. At 3 months after injection, the results for the same parameters were 0.45±0.18, 345±125 ?m respectively. At 12 months after injection, they were 0.30±0.09, 498±133 ?m respectively. Thus, best corrected visual acuity had improved and macular thickness had decreased at 3 months post-injection for the groups with intravitreal injection of triamcinolone acetonide and intravitreal injection during pars plana vitrectomy. However, these changes in best corrected visual acuity and macular thickness were not observed 12 months after injection. Conclusions: Intravitreal injection of triamcinolone acetonide had a temporary effect on refractory uveitis with cystoid macular edema (CME). However, a study that includes more participants will be necessary for conclusive evaluation.

Purpose: To investigate the effects of Anti-TNF-α (infliximab, Remicade?, Shering-Plough) on refractory uveitis. Methods: A retrospective observational survey was conducted on 12 eyes of 10 patients with refractory uveitis. These patients had no response to immunosuppresants or systemic steroid therapy and were intolerable due to drug toxicity. After an intravenous injection of Anti-TNF-α, best corrected visulal acuity was measured. Improvement in inflammation was then observed at the first, third and last month of follow-up. Results: Patients were observed for a mean period of 15 months. They received anti-TNF-α intravenously, ranging from one to eleven infusions. After infusion with Anti-TNF-α, remission of intraocular inflammation was evident in all patients within 9.7 days. Best corrected visual acuity also improved at the first, third, and last month of follow-up. Two patients were infected by tuberculosis and mumps respectively. Conclusions: There was an effect on refractory uveitis with anti-TNF-α therapy. Many participants may also require further evaluation after treatment.

Purpose: To evaluate the effect of conjunctival shield on pain alleviation during cataract surgery in conjunctivochalasis patients for conjunctiva drawn into speculum suction holes during cataract surgery. Methods: Forty patients with conjunctivochalasis undergoing cataract surgery using un aspirating speculum were evaluated in the present study. A thin piece of surgical wipe (conjunctival shield) was inserted between the lid and bulbar conjunctiva to shield the conjunctiva from the suction hole and thereby prevent it from being sucked into the hole. Additionally, patients were asked to rank pain following speculum placement both before and after conjunctiva shield insertion by visual analogue scale. Results: The pain scores were 2.50 ± 0.78 points before conjunctival shield insertion, and 1.25 ± 0.66 points after conjunctival shield insertion, which was a significant decrease (p = 0.01). In addition, the results showed a 70% reduction in pain following shield insertion. Conclusions: Conjunctivochalasis causes pain during cataract surgery when using an aspirating speculum. The conjunctival shield insertion is a safe and simple method for pain-free cataract surgery in conjunctivochalasis patients.

Purpose: To evaluate the effect of strabismus surgery on proptosis in thyroid-related orbitopathy Methods: The medical records of 22 consecutive patients (38 eyes) undergoing strabismus surgery were reviewed. Data pertaining to number of muscles operated, the length of muscle recession, prior orbital decompression, and exophthalmometry (by either Hertel or Naugle devices) were evaluated. Results: Thirty-eight eyes in 22 patients with thyroid-related orbitopathy were studied before and after the muscle surgery. The mean change in exophthalmometry for all eyes was an increase of 0.6 mm (p<0.01). Eyes with prior decompression averaged a 0.9 mm increase following strabismus surgery (p<0.01); those without decompression averaged a 0.2 mm decrease, although not statistically significant. For eyes with multiple muscles operated on a given eye averaged 1.2 mm increase; in those with one muscle operated the average increase was 0.2 mm. In cases where the inferior rectus muscle was operated on, the average increase was 0.9 mm. When the total length of muscle recession was less than or equal to 5 mm, the mean exophthalmometric change was a increase of 0.3 mm. If more than 5 mm, the mean was an increase of 0.8 mm. Conclusions: Strabismus surgery on patients with thyroid-related orbitopathy can worsen proptosis, especially those with prior decompression. When planning for orbital decompression, the surgeon should consider this effect. Patients should be made aware of possible changes to their appearance.

`Purpose: To describe femtosecond laser-assisted corneal biopsy and its use in assessing the causative organism in a case of fungal keratitis that occurred 8 months after penetrating keratoplasty. Case summary: A 27-year-old man who had undergone penetrating keratoplasty 8 months prior showed atypical diffuse corneal haze and erosion. Diagnostic corneal biopsy using a femtosecond laser was performed because of repeated negative test results for an infectious organism and a lack of improvement, despite steroid and empirical antibiotic therapy. A corneal flap 200 μm in depth and 3 mm in diameter was obtained. The biopsy showed pseudohyphae, which led to a diagnosis of Candidal keratitis. No complications occurred during the procedure. Conclusions: Femtosecond laser-assisted corneal biopsy enabled identification of the infectious pathogen. This technique is easy, safe, and rapid, and it yields a biopsy specimen with a uniform depth and precise size. Femtosecond laser-assisted corneal biopsy can be used as an accurate diagnostic method in uncertain cases of corneal ulcers.`

Purpose: To compare surgically induced astigmatism (SIA) and some corneal higher order aberrations in patients who underwent microcoaxial cataract surgery (MCCS) or conventional cataract surgery. Methods: A prospective randomized study included 60 eyes of 55 patients. Thirty eyes received MCCS using a 2.2mm clear corneal incision (group 1), and 30 eyes received conventional cataract surgery using a 2.8 mm clear corneal incision (group 2). SIA and corneal higher order aberrations were measured with a Keratometer (Humphrey, Zeiss) and i-Trace (Tracey Technologies) preoperatively, and at 1 and 3 months after cataract surgery. SIA was analyzed vectorially using the Alpins method. Results: There was no significant difference in preoperative UCVA or BCVA between the two groups. At 1 month and 3 months after surgery, SIA in group 1 was less than that in group 2, but this difference was not significant. There was no statistically significant difference in postoperative change of corneal higher order aberrations in each group at 1 month or 3 months after surgery, and there was no statistically significant difference in corneal higher order aberrations between the two groups preoperatively, at 1 month, or 3 months after surgery. Conclusions: There was no significant difference in SIA and corneal higher order aberrations between the two groups. J Korean Ophthalmol Soc 2008;49(10):1597-1602

Purpose: To report three cases of Urrets-Zavalia syndrome after deep lamellar keratoplasty. Case summary: A retrospective chart analysis of two men who underwent deep lamellar keraplasty after corneal chemical burns and one woman who was treated with deep lamellar keratoplasty due to lattice dystrophy was performed. To maintain the anterior chamber depth and prevent formation of a double anterior chamber after deep lamellar keratoplasty, air or gas (C3F8) was injected into the anterior chamber for all three cases. After injections of air or gas (C3F8) into the anterior chamber, pupillary blocks occurred and intraocular pressures increased. Afterwards, intraocular pressures were well-controlled, but the pupil remained irreversibly fixed and dilated despite the use of miotics. Conclusions: Urrets-Zavalia syndrome, a postoperative complication, was first reported in a patient who underwent penetrating keratoplasty for keratoconus. This syndrome can also occur after deep lamellar keratoplasty on rare occasions. J Korean Ophthalmol Soc 2008;49(11):1857-1861
