[The Faden operation in strabismus surgery].

PURPOSE: Is to evaluate the indications of Faden operation and the postoperative results. MATERIAL AND METHOD: We studied a number of 32 patients with convergent strabismus operated in the Universitary Eye Hospital from Cluj, during 1998-2000 at whom we performed Faden operation with conventional surgery on the medial rectus. The anAestesia was with ketamine i.v. RESULTS: The majority of patients where females (62.50%) with ages between 0-14 years. We performed surgery in cases of convergent strabismus with spasm of fixation. The postoperative results were promising; in 23 cases we obtained ortHophory, in 8 cases a remaining deviation angle (5-10 D P), and in 1 case a deviation angle above 5-10 D P. CONCLUSIONS: 1. Faden operations is indicated to correct the spatical component of the deviation angle. 2. The postoperative good results are depending on the aSsociations of Faden operation with conventional surgery. 3. Under or above correction of the strabismus is linked with a deficiency of the conventional surgery associated.

[Correlations between ocular biometry and post-surgical refraction].

PURPOSE: To show the importance of ocular biometry in establishing the power of intraocular lens. MATERIAL AND METHOD: We studied 212 eyes operated in the University Eye Hospital from Cluj-Napoca by planned extracapsular extraction with intraocular lens implantation. Before operation there was performed ocular biometry, using SRK II formulas for calculation of intraocular lens. At 6 weeks after operation, we checked the ocular refraction by dioptronometry and we established the optical correction of the patients. RESULTS: The standard error was statistically significantly in all cases. In 84.19% of cases it was performed visual acuity with optimal correction over 0.7. CONCLUSION: The ocular biometry represents significant factor in obtaining a very good visual acuity after cataract operation.

[The explantation and implantation of artificial crystalline lenses].

UNLABELLED: THE PURPOSE of the study is to evaluate the causes of explantation and replacement of different types of intraocular lenses. MATERIAL AND METHOD: We performed a study of 1060 eyes operated for cataract in the University Eye Hospital between 1992-1996, following the number of explantation and replacement of intraocular lenses (IOL), the types of IOL and the causes of explantation. RESULTS: We performed 8 explantation of IOL (0.75 g) for pseudophakic bullous keratopathy (1 case), chronic uveitis (3 cases), secondary glaucoma (2 cases), suppurative uveitis (1 case), cystoid macular oedema (1 case). From the 8 explantation of IOL, 3 were anterior chamber intraocular lenses (AC-IOL) and 5 posterior chamber intraocular lenses (PC-IOL). We performed reposition in 4 cases of IOL. The most frequent cause of explantation was chronic uveitis and secondary glaucoma. CONCLUSION: Explantation is indicated in certain cases of IOL complications without response on medical treatment.

[Etiopathogenic consideration in the development of retinal detachment in aphakic and pseudoaphakic eye].

PURPOSE: Is to evaluate the risk factors implicated in the development of retinal detachment in aphakic and pseudophakic eyes. MATERIAL AND METHOD: We studied 46 cases operated for cataract by planned extracapsular cataract extraction with or without intraocular lens, wich developed after the operation retinal detachments. RESULTS: Retinal detachment appeared in 2.98% cases of EEC with AC-IOL and in 0.56% in EEC with PC-IOL. We performed Yag laser capsulotomy in 4 cases. Retinal detachment appeared in 12 cases between 6-12 months. The most frequent breaks causing retinal detachment where "horse shoe tears" in 23.4% of cases and tears in 14.89% cases. CONCLUSIONS: 1. High myopia and peripheral retinal degenerations are risk factors in the development of retinal detachment after the cataract operation. 2. Vitreous loss facilitates the appearing of vitreo-retinal tractions followed by retinal detachment. 3. PC-IOL reduces the frequency of retinal detachment by the stabilisation of the eye and limiting the ophthalmodonesis.

[Postoperative induced astigmatism].

PURPOSE: Is to evaluate the astigmatism induced by cataract surgery, ethiological factors and ways of prophilaxies and treatment. MATERIAL AND METHOD: We followed a number of 211 eyes operated for cataract by planned extracapsular extraction with intraocular lens implantation, in Ophthalmological Clinic from Cluj-Napoca. All the pacients had limbal incision and the suture was performed with 9.0 suture, after the operation the treatment consisted in local drops with steroids. REZULTS: The astigmatism induced by the surgery was direct in 53.08% of cases and indirect in 46.92%. The position of the axes was 0-900 in 72.51% and oblique in 27.48%. The optical correction of astigmatism was with combined spherocylinder glases in 57.34% and only with cilinder in 42.65% of cases. CONCLUSIONS: 1. The induced astigmatism by cataract surgery is in relation with the incision, suture and IOL. 2. Correction of astigmatism is possible with optical correction, repearing the suture or with refractive surgery. 3. The prevention of astigmatism over 1.5 D is by using Troutmann keratometer and to evidence the congenital astigmatism.

[YAG laser capsulotomy in secondary cataract].

UNLABELLED: The purpose of the study is to evaluate the modern possibilities of performed by laser YAG in secondary cataract. MATERIAL AND METHOD: We performed a study on 200 eyes with secondary cataract operated in the University Eye Hospital from Cluj-Napoca during 1991-1997. RESULTS: We had 95 male and 105 female, with age between 30-90 years old. The capsular fibrosis was present in 86% of the cases. Secondary cataract was present in 13.33% of the cases with PC-IOL. Functional results showed a visual acuity between 0.7-1 in cases from the 50 cases review after 1 week after YAG Laser. CONCLUSIONS: 1. Secondary cataract is the most frequent complications of PC-IOL which influence the visual acuity. 2. YAG laser capsulotomy is a modem, efficient and non-invasive method to solve the secondary cataract.

[The posterior chamber artificial crystalline lens implant in the diabetic patient].

UNLABELLED: The purpose of this study is to display the influence of diabetes on the course of the operation, postoperative complications and functional results in operated primary cataract. MATERIAL AND METHODS: We performed a study on 72 eyes with cataract and diabetes operated in the University Eye Hospital from Cluj-Napoca during 1992-1997. RESULTS: From the 72 cases, 58 had diabetes noninsuline dependent. Background diabetic retinopathy was present in only 18 cases. In 71 cases it was performed EEC + IOL-CP and 1 case with open angle glaucoma we made the triple procedure (EEC + CP-IOL + trabeculectomy). In 43 cases it was striate keratitis, in 30 eyes pigmentary migration and in 4 cases uveitis. As late postoperative complication we had 10 secondary cataract and i retinal detachment. Functional results were in majority cases between 0.1-0.3. CONCLUSIONS: Diabetes do not influence the course of planned extracapsular extraction with PC-IOL, which is the best choice for the patients with cataract and diabetes. Functional results depends on the presence of diabetic retinopathy.

[Surgical treatment in strabismus with a vertical component].

In the paper we studied 87 patients with vertical or combined deviations treated in Eye Clinic from Cluj-Napoca between 1994-1998. The most patients show vertical deviation due to inferior muscle overaction (70 patients). 17 patients had a vertical deviation due to another causes (superior oblique paresis, III-nerve paresis and dissociated vertical deviations). We treated vertical deviation due to superior oblique muscle overaction only when was an important deviation in the primary position of gate. In superior muscle paresis we did a superior oblique muscle resection or weaken of inferior oblique muscle secondary overacting. In III-nerve paresis with contralateral superior rectus muscle overaction we did recession of this muscle. The results are favourable: the deviation disappear in the primary position of the gaze and decrease or disappear in the lateral gaze.

[The therapeutic aspects in intermittent divergent strabismus].

PURPOSE: Is to evaluate the possibilities of treatment in intermittent divergent squint at children and young adults. MATERIALS AND METHOD: We studied an group of 66 patients treated in the University Clinic of Ophthalmology from Cluj-Napoca. RESULTS: The most frequent type of intermiTtent divergent squint (IDS) is the type of excess of divergency (25.76%). In 46.9% the onset was between 2-6 years. In 69.7% visual acuities were equal and stereopsis was present in 74.24%. Hyperopia +/- astigmatism was present in 69.7%. The treatment of intermittent exodeviation was conservative in 51.5% and surgical for first intention in 39.3%. CONCLUSIONS: 1. The most frequent type of intermittent exodeviation is by excess of divergency. 2. The treatment of exodeviation is an optical, orthoptic and surgical treatment. 3. The surgical technique depends on the type of intermittent exodeviation.

[The functional results in primary surgical cataract associated with diabetes mellitus].

UNLABELLED: The purpose of this study is to display the influence of diabetes on the course of the operation, postoperative complications and functional results in operated primary cataract. MATERIAL AND METHODS: We performed a study on 42 eyes with cataract and diabetes operated in the University Eye Hospital from Cluj-Napoca during 1992-1996. RESULTS: From the 42 cases, 32 had diabetes non-insulin-dependent. Background diabetic retinopathy was present in only 16 cases (38%). In 33 cases it was performed EEC + PC - IOL. Postoperative, in 38 cases it was striate keratitis, in 21 eyes pigmentary migration and in 3 cases uveitis. As late postoperative complications we had 5 secondary cataract and 1 retinal detachment. Functional results were in majority cases between 0.1-0.3. CONCLUSIONS: Diabetes do not influence the course of planned extracapsular extraction with PC-IOL, which is the best choice for the patients with cataract and diabetes. Functional results depends on the presence of diabetic retinopathy.

[The results and complications of artificial lens implantation in the anterior chamber].

UNLABELLED: The purpose of the study is to make a comparison in the evolution of AC-IOL per primam and per secundam. MATERIAL AND METHOD: We reviewed 50 cases operated in the University Clinic of Ophthalmology from Cluj-Napoca since 1995-1996, 35 managed with primary and 15 with secondary AC-IOLs. RESULTS: Early and late postoperative complications are frequently present at the primary AC-IOLs. Explanation was performed in 2 cases. The functional results were superior at secondary AC-IOLs. CONCLUSIONS: AC-IOL is the solution to be chosen in case of intraoperative complication (loss of vitreous). Secondary AC-IOL is to be preferred because the postoperative complications are fewer and the functional results are better.
