Clinical and pathological study of juvenile conjunctival naevi. Methods: 16 patients younger than 20 years old were included in the study. Clinical examination were done for all cases preoperatively and for 6 months Postoperatively. Surgical excision of naevi were done followed by closure of the wound by vicryl 6-0 suture. Histopathological examination were done for All speciments. Results: The clinical and histopthological examination of all cases were recorded. The majority of cases were inflamed juvenile conjunctival naevi and the rest were Simple compound naevi. Conclusion: Compound naevi and inflammatory juvenil naevi are very common amoung The first and second decade of life. •

A naevus is a congenital hamartomatous tumor, a flat or elevated usually well circumscribed lesion that may not become pigmented untile puberty or early adulthood in. Acquired nevi are typically located near the limbus and may drap over the peripheral cornea C.21. Pigmented conjunctival naevi may obscure cysts under slit lamp examination CI'. Pigmented naevi may show inflammation and enlarge in size. The triggering factor may be the increase of ocular nerve growth factor, cosinophils and mast cells. This suggest a possible association between inflamed naevi and allergy °I. Aim of the work
Our aim in this work istestudy the clinical and histological character of these naevi specially when they enlarge in size to exclude the possible cause.
Methods
16 .patients under the age of 20 years were included in this study in Benha university and medical insurace hospitals in the period between march 2003 and march 2004. History taken and ocular clinical examination were done including visual acuity, intra ocular pressure measurement,slit lamp ,fundus and gonioscopic examination. All cases were prepared for surgery under general anasethesia. Eye lid speculem was used. Conjunctival incision with scissor was done, undermining of the conjunctival pigmented naevi with salty margin all around and remove' it. The wound was closed with

vicryl 6-0 sutures and subconjunctival ingestion of steroid and antibiotic was done. The specimens were taken, put in preservative and send to be examined histopathologically. The follow up period was 6 months.
Results
16 patients were included in this study, 12 were females and 4 were males all under the age of 20 years. Median age of patients were 13.4 (SD 5.04) years. 6 specimens (37.5%) were histologically defined as simple compound conjunctival naevi, while 10 cases (62.5%) were defined as inflamed juvenil conjuctival naevi. All lesions were near the limbus and were pigmented. 10 patients came because of a history of slight growth or congestion of the lesions and 6 patients came because of cosmetic problems. 8 patients were using antiinflammatory drops because of history of vernal conjunctivitis. When patients with inflamed :lacy' were examined, obvious papillary reactions were noted, indicated allergic conjunctivitis. But other patients with simple naevi, no allergic manifestation were observed. No postoperative complications as recurrence were observed during the follow up period. Only hematoma was observed in 4 cases postoperatively and cleared by the end of third week postoperatively. Histopathological examinations of the specimens revealed lymphocylic cells infilteration in all cases. Plasma cells were found in 4 cases and eosinophils in 10 cases. Cystic epithelial islands were found in 6 cases (fig. 1c).Nodular proliferation

Abstract Purpose: To study the changes In anterior segment configuration after phacoemulsification and intraocular lens implantation by means of ultra-sound biomicroscopy (UBM). Patients and methods : Fifteen eyes of 15 patients with senile on pre sntle cataract and no other illness were participate in this work. All pa-tients were examined with UBM before and one month after surgery. At each UBM examination, central anterior chamber depth (ACD1). depth from the cornea to the papillary plane (ACD2), angle opening distance at 500 micron from sclera, spur (AOD500) and trabecular iris angle (TIA) were recorded. Results : Central anterior chamber depth Increased after surgery as well angle opening distance and trabecular Iris angle at 500u from scler-al spur. Conclusion: After phacoemuLsification, UBM revealed that deepening of the anterior chamber and widening of its angle occurred. This finding may be of clinical importance in patients with closed angle glaucoma.
Introduction The visualization of living tis-sue at microscopic resolution is attracting attention. The majority of application appears to be devel-
oping in the 40-60MHz frequency rang where resolution on the or-der of 50 u can be achieved (Fos-ter et al.. 2000). LIBM presents us with a new method of imaging the
