Conjunctival Impression Cytology and Bulbar Surface Epithelium Changes in Patients with Psoriasis

In this study, we evaluated bulbar surface epithelium changes with conjunctival impression cytology (IC) in patients with psoriasis. Our study group consisted of 32 psoriatic patients (64 eyes), who were followed up at Dermatology Department of Dicle University Hospital. Control group comprised 32 healthy volunteers (64 eyes) who had no abnormality on routine ophthalmological examination and were in the same age and sex distribution. Specimens for conjunctival IC were obtained with a cellulose acetate filter paper from the upper bulbar conjunctiva and fixed with 70 % ethyl alcohol, 37 % formaldehyde and 20:1:1 glicial asetic acid solution. Specimens were stained with periodic acid Schiff’s and Hematoxylin-eosin. The grades of Nelson system were evaluated with light microscopy. Of the patients with psoriasis, 39 % had grade 0, 36 % grade I, and 25 % grade II conjunctival IC differentiation compared with 78, 22, and 0 %, respectively in the control group (p< 0.001). Snake-like appearance of nuclear chromatin in conjunctival epithelial cells was demonstrated in 3 % of eyes in group I but in no eyes in group II. In conclusion, we showed that there could be early conjunctival changes and squamose metaplasia as well as increased goblet cell density in patients with psoriasis when compared with control group

Surgical Success Rates for Horizontal Concomitant Deviations According to the Type and Degree of Deviation

We evaluated the correlation with success rates and deviation type and degree inhorizontal concomitant deviations. 104 horizontal concomitan strabismus cases whowere operated in our clinic between January 1994 – December 2000 were included in thestudy. 56 cases undergone recession-resection procedure in the same eye 19 cases twomuscle recession and one muscle resection, 20 cases two muscle recession, 9 cases onlyone muscle recession. 10 ± prism diopter deviation in postoperative sixth monthexamination was accepted as surgical success.Surgical success rate was 90% and 89.3% in the cases with deviation angle of 15-30and 31-50 prism diopter respectively. Success rate was 78.9% if the angle was more than50 prism diopter. According to strabismus type when surgical success rate examined; inalternan esotropia 88.33%, in alternan exotropia 84.6%, in monocular esotropia 88%and in monocular exotropia 83.3% success was fixed. Statistically significant differencewas not found between strabismus type and surgical success rate. The binocular visiongaining rate was found as 51.8% after the treatment of cases.In strabismus surgery, preoperative deviation angle was found to be an effectivefactor on the success rate

Anterior Approach in Levator Resection in Congenital Ptosis

Results of levator resection with anterior approach in cases withcongenital ptosis with levator function 4 mm or better were evaluated.12 eyelids of 12 cases with congenital ptosis who had undergone levatorresection between March 2001-March 2003 were included in this study.Visual acuity, levator function and grade of ptosis were examinedpreoperatively. Levator resection with anterior approach was performed inall cases. Full correction or ≤ 1 mm of residual ptosis with a good lidcontour is considered successful. Levator function ranged 4 to 10 mm andthe amount of ptozis ranged 3 to 7 mm. Nine of the eyelids (75%) werecorrected successfully, but 3 eyelids (25 %) were undercorrected. Theobserved complications were exposure keratopathy in 1 case and abnormallid crease in 1 case. Mean postoperative follow-up was 12.83 ± 7. 44 monhts(range 3 to 24).Due to better visualization of the anatomical structures, levatorresection technique with anterior approach can be preferred in congenitalptosis surgery
