A Case Ocular Tubereulosis Associated with Seleral Perftration

Tuberculosis, once thought to be the most common cause of uveal is now thought to be a relatively rare cause of ocular disease. This is because of a decreased incidence of tuberculosis as well as a lessened emphasis on its diagnosis. Tuberculosis of uveal tract has long been a controversial subject in ophthalmology. Several factors have been implicated including the marked pleomorphism of the lesions, owing to variations in the virulence of the invading organisms, host resistance, and the presence or absence of host immunity. Solitary choroidal tuberculoma is rare and characterized as gradually growing until it resembles a tumor projecting as a round white or yellowish globular mass into the cavity of the eye. It may progress continuously and so finally, in the absence of treatment, the sclera is involved and perforation results which is followed by phthisis bulbi or pyogenic infection and panophthalmitis. We have experienced a 19-year old female who had a solitary choroidal tumor like lesion, which about 17 months later resulted in scleral perforation, in the posterior pole of the left eye. We performed enucleation of the left eyeball under the clinical diagnosis of the maligant melanoma associated with scleral perforation and obtained the histopathological diagnosis of ocular tuberculosis.

Clinical Results of 121 Cases of Intraocular Lens Implantation

From Oct. 1985 to Mar. 1987, 141 cases of intraocuiar lenses were implanted, and 121 cases had been followed up for more than 2 months. The results were as follows: 1. Surgical technique is planned extracapsular cataract extraction(ECCE) in 81 eyes, Kelman phacoemulsification(KPE) in 21 eyes, Irrigation and Aspiration in 12 eyes, secondary implant in 4 eyes. 2. Post operative visual acuity of 0.5 or better was achieved in 112 eyes(92.5%) and or better in 75 eyes(61.9%). Average of visual acuity was 0.90 +/- 0.25 in toto, 0.88 +/- 0.24 in planned ECCE, 0.96 +/- 0.22 in KPE, 0.92 +/- 0.24 in others. There was not significant carrelation between planned EOCE and KPE(p<0.005). 3. The mean spherical equivalent of post operative corrective spectacle lens power was -0.59 +/- 1.13 in toto, -0.57 +/- 0.92 in planned ECCE. -0.85 +/- 1.13 in KPE. 4. Post operative repractive state was myopic in 98 eyes(80%), emetropic in 10 eyes(8%) and hyperopic in 9 eyes(7%).

A Case of Acute Posterior Multlfocal Placoid Pigment Epithellopathy

Acute posterior multifocal placoid pigment epitheliopathy(APMPPE), first described in 1968 by Gass, is chracterized by rapid loss of central vision secondary to multifocal, yellow-white placoid lesions at the level of the pigment epithelium and choroid and significant visual improvement after spontaneous resolution of the active lesions within several weeks or months. Fluorescein angiography shows chracteristically that the chtoidal fluorescence is not visible at the site of acute lesion in the early arterial and arteriovenous phases and become hyperfluorescent due to staining of the lesions in the late venous phases. We experienced a case of acute multifocal placoid pigment epitheliopathy in 26 years old female patient occurring in both eyes.
