Long-term Results and Complications using Scleral-fixated Posterior Chamber Intraocular Lenses

The scleral fixation of a posterior chamber intraocular lens is known to be a technique for managing cataract, aphakia, lens dislocation, pseudophakic bullous keratopathy with incomplete zonular or capsular support. We performed a retrospective review of longterm results and complications of 86 patients(103 eyes) who had a minimum of 12 months follow-up after scleral fixation of a posterior chamber intraocular lenses. At the last examination, mean postoperative corrected visual acuity is 0.7 +/- 0.28 and 62 eyes(57.4%) had a vision of 0.8 or better. Especially in aphakia, postoperative corrected visual acuity was significantly improved. The complications related to scleral fixation were exposed scleral fixation suture, glaucoma, cystoid macular edema, subluxation of intraocular lenses, retinal detachment, herpetic keratitis, vitreous hemorrhage and vitreous opacity. The other factors influenced on visual acuity were age-related macular degeneration, optic atrophy, diabetic retinopathy and clinical significant macular edema, and corneal opacity. Though these longterm results suggest that overall prognosis for visual acuity is quite good, careful assessment preoperatively and proper management are important.

Conjunctival Bacterial Flora at Birth: Comparisons between Cesarean Section and Vaginal Delivery

Conjunctival bacterial cultures for 113 neonates who were delivered by cesarean section or vaginal delivery were performed within 30 minutes after birth. These neonates were in the condition of no eye drops applied. The 43 newborns were delivered by cesarean section(CS group) and the 70 newborns were delivered vaginally(VD group). The 10 newborns(P1) (14 eyes(P2)) in the CS group and the 29 newborns(41 eyes) in the VD group showed culture positivity. These differences between two groups were statistically significant(p1, p2<0.05). The CS group had significantly fewer species and colony forming units cultured per subject (0.395 +/- 0.821(p3), 5.116 +/- 27.095(p4) than the VD group(0.971 +/- 1.393, 25.843 +/- 62.285) (p3,p4<0.05). Coagulase negative staphylococci were predominantly isolated in the CS group and coagulase negative staphylococci, gram positive bacilli, E. coli, nonfermenting bacilli, and S. aureus in the VD group. Therefore it was found that the conjunctiva of the newborns delivered by cesarean section bore significantly fewer bacteria and need less prophylactic measures than that of newborns delivered vaginally.

A Case of Treatment of a Retinal Detachment Associated with Choroidal Coloboma

Congenital coloboma which is characterized by an absence of a part of normal ocular tissues involving iris, lens, ciliary body, choroid, and optic nerve. And choroidal coloboma is a rare disease in which there are defects of a part or all parts of choroid and retinal pigment epithelium. Retinal detachment has been reported in 23-42% of the patients with choroidal coloboma, and when retinal breaks are within the area of coloboma, conventional scleral buckling technique has resulted in low rates of anatomic success. We report a case of choroidal coloboma combined by retinal detachment which was treated by pars, plana vitrectomy, fluid-gas exchange, and laser photocoagulation.
