Internal lenticonus is a very rare morphologic abnormality of crystalline lens which has been reported in only several cases in the literature. We herein reported the clinical characteristics and surgical findings of the anterior internal lenticonus accompanied by congenital nuclear cataract. Cataract extraction accompanied with intraocular lens implantation was uneventfully performed, and a good visual outcome was achieved in this case. Viral infection during embryonal and fetal period might account for the formation of the anterior internal lenticonus and congenital nuclear cataract in our case.

PURPOSE: Several articles have been published on the successful elimination of iridolenticular synechiae after cataract extraction with a neodymium YAG laser (Nd:YAG laser) and surgical synechiolysis during cataract surgery, but the indications recommending which method is proper to use for specific kinds of adhesions have not yet been established. METHODS: We retrospectively reviewed the medical records of 106 patients who had undergone Nd:YAG laser or surgical synechiolysis between January 2002 and December 2007 in our clinic. Laser synechiolysis was performed in the synechiae not exceeding the extent of one clock hour and reaching only to the iris sphincter, whereas surgical synechiolysis was performed in other diffuse and/or thick synechiae. RESULTS: Surgical synechiolysis was performed in 93 eyes, and YAG laser synechiolysis was done in 21 eyes. Increases in best-corrected visual acuity (BCVA) were observed in 61 eyes (53.51%). Intraocular pressure spikes after the procedure were present in only 4 eyes, and all of them were transient except for 1 eye, which needed additional glaucoma eyedrops. CONCLUSIONS: With suitable indications, laser or surgical synechiolysis can be performed safely, and a small rise in visual acuity may also be expected.

This study evaluated the surgical outcome and complications of phacoemulsification and the implantation of an acryl foldable intraocular lens (IOL) with a squared edge in dogs with cataracts. Thirty-two eyes from 26 dogs were examined. The mean follow up period was 75.9 days ranging from 23 to 226 days. The complications after phacoemulsification were posterior capsular opacity (PCO) around the IOL (n = 11), ocular hypertension (n = 4), focal posterior synechia (n = 4), hyphema (n = 3) and corneal ulcer (n = 2). The complications associated with the IOL were decenteration of the optic (n = 2) and ventral haptic displacement (n = 1). Most cases of PCO were found only around the margin of the IOL, and all eyes had vision during the observation period. In conclusion, the implantation of an acryl-foldable lens with a squared edge at the time of phacoemulsification is an effective method for preserving the central visual field of dogs with cataract.

INTRODUCTIONTo report surgical outcomes of 25-gauge transconjunctival vitrectomy combined with cataract surgery for the management of a variety of vitreoretinal diseases.

MATERIALS AND METHODSA retrospective, interventional case study was conducted. Chart review of a consecutive series of 150 eyes of 144 patients who underwent 25-gauge vitrectomy combined with phacoemulsification and intraocular lens implantation for epiretinal membrane (n = 62), refractory macular oedema associated with retinal vascular disorders (n = 29), idiopathic macular hole (n = 21), non-clearing vitreous haemorrhage (n = 18), rhegmatogenous retinal detachment (n = 11), tractional retinal detachment associated with proliferative diabetic retinopathy (n = 7), and subretinal haemorrhage (n = 2). Main outcome measures included preand postoperative visual acuity, operating time, intraocular pressure, intra- and postoperative complications.

RESULTSThe mean follow-up period was 9.7 months (range, 6 to 26). The mean overall visual acuity improved from 20/100 preoperatively to 20/38 at final visit (P <0.001). Statistically significant improvement of visual acuity was also observed in each subgroup. Operative time was shortened in macular surgery. No intraoperative complications were noted attributable to small-gauge instruments and no cases required conversion to 20-gauge standard instrumentation. However, 12 eyes (8%) required suture placement to at least one sclerotomy site. Postoperative intraocular pressure remained stable in most cases except 18 eyes (13%) with transient hypotony during the first week after surgery. One case of retinal detachment but no case of endophthalmitis was observed throughout the follow-up period.

CONCLUSIONS25-gauge vitrectomy combined with cataract surgery is a safe and effective system for the management of a variety of vitreoretinal diseases, especially cases requiring minimal intraocular manipulation. Further study is recommended to evaluate potential postoperative complications.

PURPOSE: Combined with vitreoretinal surgery, silicone oil endotamponade has become a standard technique and improved the prognosis of complex retinal diseases. To improve success rate of silicone oil endotamponade, the authors analysed complications and associated with other variables. METHODS: The authors analysed 90 cases of silicone oil endotamponade (102 eyes), all operated by one surgeon from 1995 to 2000 and followed-up over 6 months. The series consisted of proliferative diabetic retinopathy (48 eyes), complex retinal detachment (33 eyes), proliferative vitreoretinpathy (11 eyes) and ocular trauma (10 eyes). Analysed variables were preoperative visual acuity, rubeosis iridis, nuber of operations, duration of tamponade, emulsification of silicone oil, lentile status, anterior proliferative vitreoretinpathy, keratopathy, change of ocular tension, redetachment, macular degeneration and electroretinogram. RESULTS: Anatomic success was achieved in 95 of 102 eyes (93.1%) and functional success was achieved in 66 eyes (64.7%). Change of ocular tension over 10mmHg, anterior proliferative vitreoretinpathy and anatomical failure were statistically significant prognostic factors. CONCLUSIONS: Silicone oil endotamponade is an effective measure for complex retinal diseases, but its complication has always been an issue. If these complications can well be kept under the control, silicone oil endotamponade will become more widely used surgical modality.

PURPOSE: Protein C deficiency is an autosomal recessive disorder, which predisposes the patient to potentially blinding and widespread lethal thromboembolic complications, especially in the homozygous type. We here report the first Korean case of ophthalmic involvement and its surgical treatment in homozygous protein C deficiency. METHODS: A 3.4kg, full term girl was born by normal delivery but showed bilateral leukocoria on day 2. Laboratory results disclosed a very low protein C activity level (10%) in the patient and moderately decreased levels in the other family members. Ophthalmic examination showed bilateral corneal opacity and shallow anterior chamber. B-scan ultrasonography which showed intravitreal mass lesions without microphthalmos and a funnel-shaped retinal detachment suggested bilateral retinal dysplasia. RESULTS: As the eyes were under progression of secondary glaucoma, bilateral lensectomies were performed at 2 months old and corneal opacity was regressed to some degree. However, at 14 months old, the left eye showed moderate corneal opacity with a band keratopathy. CONCLUSIONS: Although visual outcome was very poor after surgery, we could impede or slow down the progression of secondary glaucoma and save the eyeballs in the infant with homozygous protein C deficiency.

PURPOSE: To report the results of secondary posterior chamber intraocular lens (PC-IOL) implantation in pediatric cataract eyes with microcornea and/or microphthalmos. METHODS: Retrospective studies were conducted by reviewing the charts of 26 eyes of 15 patients with secondary PC-IOL implantations for microcornea and/or microphthalmos associated with cataract in children between 1999 and 2002. The corneal diameter was 9.5 mm or less at the time of secondary PC-IOL implantation. Preoperative examinations were conducted for bilaterality, corneal diameter, eye abnormalities and systemic abnormalities. Postoperative results were evaluated in terms of visual developments, refractive changes, axial length measurements and the occurrence of complications. The follow-up period was at least one year after secondary PC-IOL implantation. RESULTS: Age at the first diagnosis for cataract with microcornea and/or microphthalmos was 2.7 months on average. Among 15 patients, 8 (53.3%) had a family history. All patients received an initial irrigation and aspiration, posterior capsulectomy, and anterior vitrectomy at 0.8 years (0.1-3.3 years) of age and a secondary PC-IOL implantation surgery at 6.7 years (1.6-17.2 years) of age on average. The postoperative follow-up period was 2.1 years (1.1-4.3 years) on average. The average power of the implanted PC-IOL was +21.2D. Postoperative complications were secondary glaucoma in two eyes, secondary pupillary membrane formation in two eyes. Best corrected visual acuities in 20 eyes in children capable of the vision test at the last follow-up were 20/60 or better in 11 eyes, 20/80 to 20/150 in eight eyes, and 20/200 or worse in one eye. CONCLUSIONS: The secondary PC-IOL implantation in pediatric cataract with microcornea and/or microphthalmos is recommended as a means of improving vision, but must be conducted carefully to avoid possible complications.

PURPOSE: Ocular perforation during lid anesthesia is rarely reported. We describe here a case of inadvertent corneal perforation and traumatic cataract that occurred during lid anesthesia in a procedure for hordeolum removal. METHODS: A 33-year-old woman presented with a sudden visual loss of her left eye. She had undergone hordeolum removal the day before at a local clinic. On ophthalmologic examination, the cornea was perforated and the lens cortex was extruded into the anterior chamber. After cataract removal and IOL implantation, antibiotics were injected into the vitreous. RESULTS: Her final visual acuity of the left eye was 20/20. Postoperative specular microscopic examination revealed a normal-range endothelial cell count, coefficient of variation, and hexagonality despite the intracameral lidocaine injection. CONCLUSIONS: Anesthetic injection of an infected lid should be done with great caution. Although there are possibilities of corneal endothelial toxicity and endophthalmitis in case of intracameral lidocaine injection through the infected lid, yet proper management may save the patient's vision without complications.
