A Modified Surgical Technique for 2 Cases of Conjunctivochalasis Near the Lower Punctum

Conjunctivochalasis is an isolated bilateral condition in which redundant conjunctival tissue overlies the lower eyelid margin or covers the lower pmctum. It produces tearing by mechanical obstruction of the lower punctum and/or mechanical disruption of normal outflow of the lacrimal film. A modified surgical technique, simple local excision of redundant conjuctiva in the crescent shape along the plica semilunaris and the lower bulbar conjunctiva between limbus and lower fornix, relieved epiphora in two male patients with redundant conjunctiva near the lower punctum. Surgery was done under the local anesthesia without postoperattve complications. Authers emphasize the importance of careful examination of conjunctivochalasis during ocular examination of patient complaining tearing.

A Case of Solitary Choroidal Tuberculoma

Solitary choroidal tubercle is rare disease nowadays although it was frequently reported in the old literatures. It is characterized by indefinite yellowish-white round nodule in the posterior pole of the eyeball in young adults with inactive disease. It is sometimes protruded toward vitreous cavity with retinal necrosis, vitreous opacity and cyclitis. Authors experienced a case of solitary choroidal tubercle which had been misdiagnosed as a malignant melanoma. We confirmed it by pathologic findings.

The Exerimental Study on Possibility of Development of Lenticular Opacity after Argon Laser Retinal Photocoagulation

Lenticular bum can occur as complication after laser iridotomy or retinal photocoagulation. Some authors have, indeed, reported the cases in which focal lenticular opacity developed after laser iridotomy or retinal photocoagulation. Fortunately, it was not progressive in short-term follow up study. When argon laser beam penetrates ocular media, a portion of it is absorbed by lens. So visible lenticular opacity is not developed after argon retinal photocoagulation if lens is clear. But it is not known whether subclinical lenticular opacity can occur after argon laser retinal photocoagulation. We focused argon laser beam onto anterior lens capsule in 35 black and brown rabbit and evaluated development of subclinical lenticular opacity with densitometer 1 and 8 weeks later. We also analyzed lens protein 1 week later. Argon laser energy used was below 20 Joules. The following results were obatined. 1. Lenticular opacity was detected by densitometer in all cases, but it was not detected by slit-lamp. 2. Amount of lenticular opacity was in direct proportion to argon laser energy(p<0.001). 3. Lenticular opacity detected on the 1st week by densitomer was not detectable on the 8th week. 4. The lens protein changes of senile cataract were not found in the lenticular opacity detected on the 1st week.
