[Rhegmatogenous retinal detachment in children and youth--chosen epidemiological features].

PURPOSE: To assess chosen epidemiological features (risk factors) of rhegmatogenous retinal detachment in young patients. MATERIAL AND METHODS: Retrospective evaluation of patients aged up to 18 years with rhegmatogenous retinal: detachment hospitalized in the Department of Ophthalmology, University of Medical Sciences of Bydgoszcz--in the period between 1993-2003. Studied group comprised 37 patients aged from 2 to 18 years. Excluded were the patients with retinopathy of prematurity. RESULTS: Mean age in the group studied was 12.6 (SD=3.6) years, over 80% were male. In 88.9% at least one risk factor was found--the most common of which was history of trauma (52.7%). Myopia was diagnosed in 27.7% of cases, in 8.3% patients cataract surgery had been performed prior to retinal detachment. In 8.3% of patients in group studied revealed congenital structural abnormalities. One patient (2.8%) had toxocariasis. Bilateral retinal detachment occurred also in one patient. The macula was detached in 75% and total retinal detachment was present in 38.8% of cases. CONCLUSIONS: The most common risk factor in the group studied was history of nonsurgical trauma. Prevalence of macular detachment was noted.

[Astigmatism after cataract surgery].

PURPOSE: To evaluate postoperative astigmatism after cataract surgery. MATERIAL AND METHODS: The studied group consist of 135 patients subjected to cataract surgery; 75 patients (75 eyes) had extracapsular cataract extraction with 12 mm corneoscleral incision (group I); 30 patients (30 eyes) had phacoemulsification with 3.5 mm corneal incision (group II); 30 patients (30 eyes) had phacoemulsification with 3.5 mm tunnel incision (group III). Astigmatism was measured on the 6th day and 2 years after surgery. RESULTS: Mean astigmatism on the 6th postoperative day was 4, 19 D (SD = 1.20) for group I, 2.50 D (SD = 0.47) for group II and 1.79 D (SD = 0.61) for group III. The differences between all the groups were statistically significant. The astigmatism assessed 2 years after surgery returned to preoperative values and there was statistic difference only between group I and III. CONCLUSION: Two years after cataract surgery astigmatism is comparable with the preoperative values irrespective of the operation technique.

[Senile and presenile cataract: comparison of patients operated in the year 1990-2000].

PURPOSE: To compare some epidemiological features (e.g. mean age) of patients operated for senile and presenile cataract in the year 1990 and 2000. MATERIAL AND METHOD: Data of 106 consecutive patients with senile or presenile cataract operated in May 1990 and 110 patients operated in April and May 2000, were compared. Some cataract risk factors were analysed: cataract in family, diabetes, steroid therapy, refractive error, rural residency, outdoor occupation, smoking., visual acuity and age of patients. RESULTS: There was significantly higher age (69 vs. 60 years) and lower number of patients with very low visual acuity (less than 0.1) in group undergoing cataract surgery in 2000. We did not noted significant differences regarding sex, cataract in family, presence of diabetes, steroid therapy, myopia, rural residency, outdoor occupation, smoking. CONCLUSIONS: In 10 years period increase of age and decrease in number of patients with very low visual acuity in group operated for senile and presenile cataract could be observed.

[Late results of endothelial cell loss after cataract surgery].

PURPOSE: To evaluate endothelial cell loss rate after cataract surgery in 5 years-long period. MATERIAL AND METHOD: The studied group comprised 115 patients (66 females and 49 males) who had undergone senile and presenile cataract surgery. Mean age was 60 years (SD = 90). In 60 patients extracapsular cataract extraction and in 55 phacoemulsification have been performed. Mean central corneal thickness was measured before and 2 days after cataract surgery. Mean central endothelial cell density was assessed preoperatively, as well as 1, 3, 6 months and 2, 5 years after operation. RESULTS: Mean endothelial cell loss was: 76% 1 month after surgery, and 97% 3 months, 110% 6 months, 124% 2 years, 140% 5 years postoperatively. CONCLUSIONS: Enhanced endothelial cell loss could be observed even 2 years after surgery. 5 years postoperatively physiological loss rate is attained. Initial postoperative increase in central corneal thickness is an important marker of subsequent endothelial cell loss.

Axial length measurements after cataract surgery in adults.

UNLABELLED: The purpose of the study was to check the difference in eye axial length before and after cataract surgery and to find out the possible correlation with refraction changes. The axial length was measured by ultrasound before and after cataract extraction with intraocular lens implantation. Keratometry measurements were also performed. The study comprised 32 eyes. The mean difference in axial length was 0.53 mm. The mean difference in keratometry was 0.37 D. There was no correlation between these values. CONCLUSION: The changes in axial length are not due to corneal curve changes. Perhaps in pseudophakic eyes different ultrasound velocity should be used.
