1/22. Sensory deviations subsequent to senile cataract.

    PURPOSE: To evaluate the effect of extracapsular cataract extraction with posterior chamber intraocular lens (IOL) implantation in patients with sensory deviations subsequent to senile cataract. methods: Twenty patients with dense cataract and associated sensory deviations underwent follow-up between April 1996 and April 1998 after extracapsular cataract extraction with posterior chamber IOL implantation in the deviating eye. All patients underwent follow-up for a minimum period of 6 months. RESULTS: Preoperatively, all patients had a visual acuity of PL positive (perception of light present) and PR (projection of rays) accurate in the deviating eye. Two patients had an esodeviation, and 18 patients had an exodeviation. Postoperatively, all patients had a corrected visual acuity of 20/40 or better in the operated eye at 12 weeks. Nineteen patients had ocular alignment within /-8 prism diopters of orthophoria at 12 weeks. CONCLUSION: Sensory deviations subsequent to senile cataract usually resolve spontaneously after cataract surgery if visual gains are 20/40 or better. The prognosis for binocular vision is good.

2/22. Successful surgical rehabilitation of children with traumatic corneal laceration and cataract.

    OBJECTIVE: To evaluate the visual and refractive outcome of corneal transplant surgery, cataract extraction, and intraocular lens (IOL) implantation in children with traumatic corneal laceration and cataract. DESIGN: Retrospective, noncomparative case series. PARTICIPANTS: Five patients, 7 years of age or younger, who underwent penetrating keratoplasty, cataract extraction, and IOL implantation for traumatic corneal laceration and cataract were identified. MAIN OUTCOME MEASURES: Each case was analyzed retrospectively for the following factors: preoperative findings; surgical technique, including management of the posterior capsule; measurement of axial length and keratometry; calculation of IOL power, style, and type of IOL implanted; graft clarity; final visual acuity; and final refraction. RESULTS: The five children ranged from 3 to 7 years of age at the time of trauma. All had primary repair of their injury before referral. Each patient was observed for more than 2 years. Each had a posterior chamber IOL placed in the sulcus. After surgery, no severe complications were observed. The preoperative visual acuity ranged from 20/400 to light perception. After surgery, all five patients had clear grafts and an improved visual acuity ranging from 20/20 to 20/400. The final spherical refraction in each patient was within 3.75 diopters (D) of plano, with 1.50 to 3.25 D of cylinder. CONCLUSIONS: Successful surgical rehabilitation was accomplished in these patients. Despite their young age and the difficulty in determining IOL power, combining surgery and aggressive amblyopia therapy resulted in visual rehabilitation with refractions approaching emmetropia.

3/22. A case of angle-closure glaucoma, cataract, nanophthalmos and spherophakia in oculo-dento-digital syndrome.

    BACKGROUND: We report a new case of oculo-dento-digital syndrome. methods: Case report. RESULTS: We saw a 34-year-old women with oculo-dento-digital syndrome. visual acuity was no perception of light (RE) and 1/35 (LE). Biomicroscopy revealed a flat anterior chamber and an advanced cataract. The intraocular pressure (IOP) was 60 mmHg in both eyes. Ultrasonographic biomicroscopy demonstrated a closed chamber angle in both eyes. Measurements of the axial length and of the diameter of the lens were 18.7 mm/6.0 mm for the RE and 18.7 mm/5.8 mm for the LE respectively. In the time following we conducted a cyclodestructive procedure in the RE and a cataract extraction with implantation of an intraocular lens in the LE. This led to a considerable reduction of the IOP in the RE and combined with local therapy to IOP regulation in the LE. CONCLUSION: In this patient nanophthalmos, cataract and spherophakia led to angle-closure glaucoma in both eyes. We recommend early monitoring of IOP, axial length and lens diameter. This case demonstrates that an early cataract extraction might beneficially influence the natural course of the disease.

4/22. Calcified cataractous lens.

    We report a calcified cataractous lens in a 24-year-old man who had retinal degeneration in the right eye since childhood. The visual acuity had dropped to light perception. Clear corneal phacoemulsification was performed, and the shell of a 5.4 mm x 4.0 mm x 2.0 mm calcified substance was removed with a forceps using the can-opener technique. The specimen was analyzed using radiological study, histopathological examination, chemical element analysis, and transmission electron microscopy. Four years postoperatively, the patient's visual acuity was 20/200.

5/22. neodymium:YAG laser iridotomy in the initial management of phacomorphic glaucoma.

    Acute angle-closure glaucoma can be triggered by a mature or intumescent cataract, and occurs in eyes with open angles, as well as in those with narrow, occludable angles. This is encountered more in developing countries, where patients present late. They tend to wait until the cataract becomes mature, because it is common belief among these patients that cataracts should not be operated on until vision drops to the level of hand movements or light perception. The authors reviewed the charts of 10 patients who were treated for phacomorphic glaucoma, by first undergoing neodymium:YAG (Nd:YAG) laser iridotomy. In all patients, the acute angle-closure glaucoma attack could be reversed or prevented by the iridotomy, before subsequent cataract extraction. The value of Nd:YAG laser iridotomy in the initial management of phacomorphic glaucoma is discussed.

6/22. Management of corneal ectasia and cataract following photorefractive keratectomy.

    A 42-year-old man was referred to our clinic 18 months after bilateral photorefractive keratectomy (PRK). He had been on topical prednisolone acetate for 12 months because of post-PRK grade 4 haze. On his first visit, visual acuity was limited to light perception in both eyes because of moderate haze, significant corneal ectasia, and a white cataract. A 2-step surgical approach was elected in both eyes. First, a deep anterior lamellar keratoplasty was performed. Six weeks later, phacoemulsification with intraocular lens implantation was performed. Compared with a triple procedure combining penetrating keratoplasty and cataract surgery in 1 stage, the 2-step approach may lower the risk for corneal graft rejection and reduce ametropia.

7/22. Traumatic aniridia after small incision cataract extraction.

    INTRODUCTION: phacoemulsification and falls are both common in the elderly population. We present a case of acquired total aniridia and vitreous haemorrhage occurring as a result of trauma in a pseudophakic eye. methods: Interventional case report with history, clinical photograph and discussion with literature review. RESULTS: A previously healthy 74-year-old Caucasian female was referred with a painful left eye and poor vision following a fall and trauma to the left side of her face. Initial examination confirmed visual acuity of perception of light with total hyphaema and vitreous haemorrhage. Subsequent examination revealed complete aniridia with an intact capsular bag and well-centred posterior chamber intraocular lens and attached retina. Final visual acuity after treatment was 6/9. CONCLUSIONS: Blunt trauma may cause total iris disinsertion in and expulsion from pseudophakic eyes. This relatively novel injury may present increasingly commonly to casualty departments and ophthalmologists.

8/22. Poikiloderma congenitale: case report and review of the literature.

    Since birth an 8-year-old girl had a rash on both cheeks, consistent clinically and histologically with poikiloderma. She also had visual impairment to the extent of light perception only, due to microthalmia and dense scleralization of the corneas. These features were considered consistent with a diagnosis of rothmund-thomson syndrome.

9/22. Bilateral blinding uveitis in a child after secondary intraocular lens implantation for unilateral congenital cataract.

    A 3-year-old boy underwent secondary implantation of an iris supported intraocular lens following extraction of a unilateral congenital cataract. Eight months later, he developed a bilateral plastic uveitis which, in spite of intensive medical treatment, resulted in NPL (no perception of light) in the implanted eye and 2/60 vision in the fellow eye. Sympathetic ophthalmia possibly played a role in the pathogenesis of the uveitis.

10/22. Ocular trauma caused by exploding glass bottles containing dry ice and water.

    We treated three patients with severe ocular injuries caused by exploding glass bottles containing a mixture of dry ice chips and water. One patient had a corneal laceration and traumatic cataract with several retained intraocular glass fragments. The second had a scleral laceration without corneal or lenticular involvement. The third suffered a corneal-scleral laceration, with a total retinal detachment. Following surgery, two patients recovered 20/20 vision; the third patient regained only light perception.
