[Analysis of 100 cases of retinal detachment treated with conventional surgery in the years 1997-1998].

PURPOSE: The observed increasing number of severe cases of retinal detachment was the ground of the attempt to state the causes of this phenomenon. MATERIAL AND METHODS: Retrospective evaluation of 100 consecutive cases of retinal detachment operated on with conventional methods between September 1997 and October 1998 was performed. The following data were analysed: sex and age of patients, period between the first symptoms and time of diagnosis and surgery. The clinical characteristics of retinal surgery comprise: extent of detachment, macular involving, type and number of breaks, degenerations and PVR. RESULTS: In the majority of cases very severe retinal detachments were observed, including 3-4 quadrants, with large tears or multiple breaks, with PVR B or C. Duration of the detachment ranged from several days in very few cases to several months, on average lasting several weeks. Attachment of the retina was achieved in 80 cases, improvement of the visual acuity in 47. CONCLUSION: Our data indicate the necessity to improve the early diagnosis of retinal detachment and changes predisposing to its development.

[Use of cryotherapy in retinopathy of prematurity].

PURPOSE: To present our experiences in cryotherapy for ROP. MATERIAL AND METHODS: From October 1991 to August 1995, transscleral cryotherapy was applied in 128 eyes of 70 babies with ROP. There were 34 girls and 36 boys with birth weight between 650 g and 1990 g and gestational age from 24 to 36 weeks. In above 90% of cases, ROP reached zone II and stage 3 with "plus" disease. In 84% of the eyes the extent of ROP was greater than 5 clock hours. Prethreshold severity was diagnosed in 7 and threshold in 110 eyes. In 11 eyes these categories could not be seventy determined. The chronologic age of infants at cryotherapy ranged from 8 to 22 weeks, mean 12 weeks. In all cases, cryotherapy was carried out under general anesthesia using a technique described in CRYO-ROP study. No serious complications during or after cryotherapy were observed. RESULTS: Favorable structural outcome was found in 119 eyes of 70 treated infants. In 82 eyes of 46 infants, with at least 12-month follow-up examination, also functional outcome was evaluated, basing on the examination with the Teller Acuity Card Procedure; the results were favorable in 57% of the eyes. Structural and functional outcomes were in agreement in 47 of the 82 eyes and discordant in 33. CONCLUSIONS: Our experience confirms the benefit of cryotherapy in the treatment of active ROP. In most cases cryotherapy should be applied in threshold ROP but in some cases especially in those with very rapid progression it should be done earlier. Because of the unpredictability of the natural course of ROP it is essential to use the scheme of ophthalmological examinations proposed by CRYO-ROP Study.

[Conventional methods in retinal detachment surgery].

PURPOSE: To evaluate the usefulness of conventional methods in retinal detachment (RD) surgery basing on the relationship between factors characterizing clinical picture of the RD, the type and course of surgical procedures and the retinal reattachment. MATERIALS AND METHODS: 252 patients (252 eyes), operated on in the last 5 years in our clinic were enrolled in the studies. There were 120 men and 132 women, aged 9 to 83, mean 53. In all cases scleral buckling procedures with silicone band or sponge and cryocoagulation of the breaks were used. The relationship between retinal reattachment and the following parameters were examined: visual acuity, retinal degenerations, myopia, extent of the detachment, number and kinds of breaks, macular involvement, state of vitreous, PVR, intraocular pressure, extent of scleral buckling, subretinal fluid drainage and intra- or post-operative complications. RESULTS: Retinal reattachment was achieved in 82% of the eyes with one operation and additionally in 7% after reoperation. The significant relationship was found between: visual acuity, intraocular pressure, extent of the detachment, number of breaks, PVR, extent of scleral buckling and retinal reattachment. CONCLUSION: PVR is a significant cause of failure in RD surgery with conventional methods and PVR grade C is the threshold beyond which the percentage of reattachments decreases to about 50%. Value of other risk factors, determining severity of RD is not certain for prognosis. Cerclage with silicone band is a method of choice in the majority of RD with PVR grade B and C. Our observations do not confirm the reports of severe complications caused by cerclage, which might be connected with excessive tightening of the band.

[Use of cryopexy in treatment of retinoblastoma].

UNLABELLED: The aim of this work is to present our own experience in the treatment of retinoblastoma with cryopexy. MATERIAL AND METHODS: 24 children were observed, among whom 23 had bilateral and 1 unilateral retinoblastoma. We applied transconjunctival cryopexy to small neoplasmatic foci in retina located anterior to the equator. In 21 eyes this treatment was supplementary to brachytherapy and photocoagulation. We used probes of temperature -65C. Each freezing lasted about 20 seconds. The treatment was repeated every 6-8 weeks. In some cases different degree of post-surgical hemorrhages occurred. RESULTS: In 1/4 of cases already after a single freezing the tumour was destroyed and cicatrized. Only in 2 out of 24 treated eyes the desired effect was not reached. CONCLUSION: Cryopexy is an effective method of treatment of small foci of retinoblastoma located in the periphery of the eye fundus. This method is usually supplementary to brachytherapy.
