OBJECTIVE Scleral perforation is a rare complication occurring after pterygium excision often leading to scleral ulceration and loss of vision. Our purpose is to evaluate the long-term effectiveness and safety of tenonplasty and amniotic membrane transplantation in the management of scleral perforation after pterygium excision. PATIENTS AND METHODS We performed a retrospective study on patients with scleral perforation after pterygium excision that underwent tenonplasty and amniotic membrane transplantation at Chang Gung Memorial Hospital from 1997 to 1999 and followed up for at least 12 months postoperatively. RESULTS There were 6 patients, 1 male and 5 females ranging in ages from 46 to 71 years (mean, 63.3). The interval between pterygium excisions to scleral perforation ranged from 3 to 20 years. There were no recurrences during the follow-up period of 12 to 24 months (average, 18.3 months). CONCLUSIONS Tenonplasty and amniotic membrane transplantation appears to be a relatively simple, safe, and effective method for treating scleral perforation after pterygium excision.

The implantable miniaturized telescope (IMT) is the first intraocular magnifying system proposed for optical correction in patients with age-related macular degeneration (ARMD). The optical component is embedded in a carrying device designed as an intraocular lens that is implanted after cataract surgery. In this study, we report findings on an IMT that was explanted because of aqueous infiltration into its optic and describe the configuration of this device and the surgical technique required for its implantation. The patient, a 75-year-old male with bilateral cataract and nonexudative ARMD, underwent phacoemulsification with implantation of an IMT in the right eye. The rigid device, weighing 46.1 mg in aqueous, has an overall diameter of 13.5 mm and requires implantation through a large limbal incision. It is fixated at the 6 to 12 o'clock meridian. Follow-up examination revealed the presence of numerous droplets inside the IMT optic. The device was explanted and sent to our center for evaluation. A large fissure was found on the carrying device. However, it was unlikely the site for aqueous infiltration. Microdefects at the level of the sealing of the optical cylinder appeared to provide the opening for the inflow of aqueous that formed droplets. Based on the findings of this report the manufacturer has modified the sealing technique to avoid this complication. Current clinical trials are now ongoing to assess the efficacy of this device in providing visual rehabilitation for ARMD patients.

A case of intraosseous orbital hemangioma is reported to alert surgeons to possible intraoperative hemorrhage during excision of such a lesion. A slowly enlarging mass was excised from the orbital rim of a 49-year-old woman. The clinical diagnosis was not suspected. In retrospect, roentgenographic findings included a focal honeycombed pattern of the zygomatic bone. Surgery was complicated by persistent low-volume bleeding. Histology showed endothelial-lined blood-filled channels within the bone. Intraosseous orbital hemangioma is a rare, benign neoplasm that can often be diagnosed clinically by characteristic roentgenographic findings. Observation should be considered as a therapeutic alternative when the radiographic diagnosis is established and when ocular function is not compromised.

BACKGROUND AND OBJECTIVE To identify the causes of congenital nasolacrimal duct obstruction using intranasal endoscopy. PATIENTS AND METHODS Eleven children with symptoms of epiphora since birth were selected for treatment. A silicone tube was inserted after identifying the causes of prior probing failures by observing the probing tip directly with intranasal endoscopy. RESULTS As confirmed through intranasal endoscopic examination, tearing was caused by mucosal obstruction, submucosal passing of the probe, pus collection, and inferior turbinate impaction. The probe passed into the submucosal space in 5 patients and, by performing probing medially instead in the usual posterolateral direction, probing succeeded in 4 patients. One case was accompanied by a bone abnormality; we bent the probe tip into the nasal cavity to form the lacrimal pathway. CONCLUSION By using intranasal endoscopy, a silicone tube can be inserted under direct visualization and any causative abnormalities can be identified. This can also minimize the intranasal trauma sometimes caused by blind probing.

Posner-Schlossman syndrome (glaucomatocyclitic crisis) is a condition of unknown etiology. Patients present with blurred vision, show minimal anterior chamber activity, and raised intraocular pressure (IOP). Corneal edema may cause colored halos. The condition tends to be recurrent, usually responding to a topical steroid and ocular hypotensives. The eyes appear normal between attacks. We present a patient who had bilateral Posner-Schlossman syndrome and underwent filtering surgery to control raised intraocular pressure in both eyes. During the follow up of more than 4 years, the control of IOP was good and he had no further attacks.

BACKGROUND AND OBJECTIVE To evaluate the efficacy of topical anesthesia as an alternative to peribulbar or retrobulbar anesthesia in phacoemulsification and intraocular lens implantation combined with our modified 2-port pars plana vitrectomy technique (phacovitrectomy). PATIENTS AND METHODS Phacovitrectomy using topical anesthesia (4% lidocaine drops) was prospectively performed in 105 eyes with cataract and varied vitreoretinal pathology. In 75 eyes (71.4%), phacovitrectomy was combined with argon laser photocoagulation (endolaser). Preoperative and intraoperative sedation of varying degrees was necessary. Subjective pain and discomfort were graded from 1 (no pain or discomfort) to 4 (severe pain and discomfort). RESULTS All patients had grade 1 pain and discomfort during most of the procedure. All patients had grade 2 (mild) pain and discomfort during pars plana sclerotomies, external bipolar cautery, and conjunctival closure. No patient required additional retrobulbar, peribulbar, or sub-Tenon's anesthesia. CONCLUSION This technique avoids the risk of globe perforation, retrobulbar hemorrhage, and prolonged postoperative akinesia of the eye. With appropriate case selection, topical anesthesia is a safe and effective alternative to peribulbar or retrobulbar anesthesia in phacovitrectomy.

BACKGROUND AND OBJECTIVE To evaluate the incidence of postoperative opacification of hydrophilic acrylic intraocular lenses (IOLs) and discuss the surgical management. PATIENTS AND METHODS Seventy-two eyes of 72 consecutive patients who received the same type of hydrophilic acrylic IOL (Intraocular Optical International, I.O.I., California, USA) after uneventful phacoemulsification were evaluated retrospectively. Systemic status, follow-up time, recognition time of IOL opacification, time lapse between implantation and explantation, and surgical technique during explantation were reported. RESULTS IOL opacification was noted in 3 patients (4.1%). Time lapse between implantation and first recognition of opacification was 6.3+/-1.5 months (range: 5-8 months). Two of the patients had insulin-dependent diabetes mellitus and both were on renal dialysis for diabetic nephropathy, whereas one had no systemic disease. Opacified hydrophilic acrylic IOLs were exchanged with Acrysof IOL, and no further opacification occurred after lens exchange. CONCLUSION Use caution on implantation of hydrophilic IOLs because late opacification is a serious complication requiring further surgery.

BACKGROUND AND OBJECTIVES To compare the safety and efficacy of conjunctival rotation autograft to conjunctival autograft in primary pterygium surgery. PATIENTS AND METHODS A prospective randomized study was performed of 39 eyes in 31 patients who had undergone pterygium surgery. Nineteen eyes were treated by conjunctival rotation autograft (Group A). Twenty eyes were treated by conjunctival autograft (Group B). Follow up ranged from 8 to 12 months (mean 11 months). Recurrence was defined as postoperative regrowth of 2 mm fibrovascular tissue onto clear cornea in the area of previous pterygium excision. Four eyes were excluded from the study. Delayed wound healing occurred in 11.76% of eyes, and 5.88% of eyes had persistent congestion in Group A. A loose graft was present in 5.55% of eyes, and 5.55% of eyes had dellen formation in Group B. CONCLUSION We conclude that conjunctival rotation autograft and conjunctival autograft are both equally effective methods to reduce the recurrence rate after pterygium surgery. Conjunctival rotation autograft can be tried as an alternative attractive procedure for pterygium surgery to reduce the chances of recurrence. However, a larger, randomized, prospective double masked study with more patients and a longer follow up will eventually demonstrate the superiority of one procedure over the other.

The injection of cell suspensions or drugs into the subretinal space is a new promising option of vitreoretinal surgery for the treatment of degenerative retinal disorders. We used a manual oil-hydraulic microinjection pump to subretinally inject suspensions of retinal pigment epithelial cells in Royal College of Surgeons rats and in patients suffering from age-related macular degeneration with geographic atrophy. The histological examination of the treated rat eyes showed that cell suspensions could be placed precisely in the subretinal space. Intra- and postoperative outcome of the patients in the clinical trial revealed no retinal complications during 6 months of follow up. We suggest the oil-hydraulic microinjection pump to be a valuable instrument for controlled and precisely dosed atraumatic infusion or aspiration of small volumes of cell suspensions, fluids or drugs in vitreoretinal surgery.

BACKGROUND AND OBJECTIVE To describe our excisional technique for lower eyelid epiblepharon to reduce a medial undercorrection and to provide a guide for the excision amount using a classification system of epiblepharon according to the skin fold height. PATIENTS AND METHODS After classification, an elliptical excision of skin and orbicularis muscle, including that below the lower canaliculus after tarsal suturing of the upper edge of the incised skin, was consecutively performed for 111 eyelids of 58 patients. The widest width of the excisional ellipse was measured. RESULTS The results were successful in 108 eyelids. The mean widest width of the excisional ellipse was 1.1, 1.7, 2.5, and 3.0 mm in Class I, II, III, and IV epiblepharons, respectively. CONCLUSION This surgical technique is effective for the correction of epiblepharon, and it is easy to determine the amount of excision. Using this technique, a 1 mm to 3 mm width of excision is sufficient.
