Clinical Outcome after Implantation of Intraocular Lens in Pediatric Cataract

Safety and effect of intraocular lens implantation in pediatric cataract patients were studied. And properness of intraocular lens along postoperative refractive changes was evaluated. In the department of ophthalmology, Yeung-Nam University college of medicine, twenty-eight patients were performed lens aspiration with intraocular lens implantation for pediatric cataract from May 1992 to October 1996. Preoperative and postoperative visual acuity, refractive power and postoperative complication along operative methods were evaluated, retrospectively. After follow up period of 6-30 months(mean 17.7 months), visual improvement more than 2 lines was noted 28 eyes(77.8%) by Hahns visual acuity chart. The trends of myopic shift had no significance in statistically, it is proper that we selected intraocular lens power adjust to emmetropia in over 3 years old patients. The difference between preoperative and postoperative refractive power measured within 0 and -2 Diopters in 30 eyes(83%). Aimed intraocular lens power was calculated by using SRK/T fomula for emmetropia and adjustment for refractive error of fellow eye. Best corrected vision was obtained after medical treatment of amblyopia.

Classification and Therapeutic Effect of Benign and Malignant Eyelid Tumors

The authors reviewed 73 cases of the eyelid tumors diagnosed histopathologically at Department of Ophthalmology, Yeungnam University Medical Center from March, 1984 to December, 1995. Twenty-three persons were men and fifty persons were women. The benign tumors were distributed evenly in all decades, but the malignant tumors were noted frequently in seventh and eighth decades. Histologically, benign tumors were 58 cases and malignant tumors were 15 cases. The frequency of benign eyelid tumors was noted in this order : nevus, cyst, squamous papilloma, hemangioma, seborrheic keratosis. Malignant eyelid tumors included 10 cases of basal cell carcinoma, 5 cases of meibomian gland carcinoma. The location of the benign tumors of the lids was noted in this order : the upper eyelid(30 cases), the lower eyelid(23 cases), the medial canthus(3 cases) and both eyelids(2 cases). In malignant tumors, the locations of basal cell carcinoma were the lower eyelid(6 cases), the medial canthus(3 cases) and the upper eyelid(1 case). Meibomian gland carcinoma was found in the upper eyelid(3 cases) and in the lower eyelid(2 cases). Excisional biopsy was performed in all of benign tumors(58 cases, 100%). For the treatment of the malignant tumors, simple excision(5 cases, 33%), excision and reconstruction(6 cases, 40%), excision and skin graf(3 cases, 20%) were performed. Exenteration and several courses of radiation therapy were carried out for a recurred meibomian gland carcinoma(1 case, 7%).

A Case of Unilateral Retinitis Pigmentosa

Retinitis pigmentosa has been recognized as a symmetrical, bilateral, hereditary, tapetoretinal degeneration with night blindness, visual field loss, and abnormal ERG. Unilateral retinitis pigmentosa is a rather rare disease. Pedraglia described first reported a case of suspected unilateral retinitis pigmentosa in 1865. Francois and Verriest proposed the following four criteria of the unilateral retinitis pigmentosa: the presence of functional changes ophthalmoscopically typical primary pigmentary degeneration in the affected eye, the absence of a tapetoretinal dystrophy in the fellow eye with normal ERG over five years and exclusion of the inflammatory cause in the affected eye. We report a case of unilateral retinitis pigmentosa in 29 year-old female who has been followed for over five years.
